I have this file structure:
> APPLICATION 1
>> CONTROLLER (@JuniorProgrammers)
>> MODELS (symlink to SHARED/MODELS)
>> VIEWS (@Designers)
> APPLICATION 2
>> CONTROLLER (@JuniorProgrammers)
>> MODELS (symlink to SHARED/MODELS)
>> VIEWS (@Designers)
> SHARED
>> MODELS (@SeniorProgrammers)
I need php to be able to read Folder 1.1 contents, but programmers who FTP into Folder 1 won't be able to read the symlink (they CAN see the symlink, but not FOLLOW it including all reads, and writes).
The @ is the groups of users that have read/write access of each layer.
|
Symlinks themselves have 777 because in Unix, file security is judged on a file/inode basis. If it's the same data they're operating on, it should have the same security conditions, regardless of the name you gave the system to open it.

[root@hypervisor test]# ls -l
total 0
lrwxrwxrwx. 1 root root 10 Jun 8 16:01 symTest -> /etc/fstab
[root@hypervisor test]# :-(
Since permissions are set on the inode, it won't work with hard links even:

A symlink isn't an inode (which actually stores the data you're wanting to secure) ergo in the Unix model it complicates things by having two different sets of permissions for protecting the same data.
It sounds like this is an attempt to give different groups of people different levels of access rights to the same file. If that's the case you're actually supposed to use POSIX ACL's (via setfacl and getfacl) to give the files appropriate permissions on the target of the symlink.
EDIT:
To elaborate on the direction you're probably wanting to go in, it's something like:
# setfacl -m u:apache:r-- "Folder 2.1"
# setfacl -m g:groupOfProgrammers:--- "Folder 2.1"
# setfacl -m g:groupOfProgrammers:r-x "Folder 1"
The above gives the apache user (substitute with whatever user your apache/nginx/whatever is running as) read-only access to the target of the symlink, and gives groupOfProgrammers read access to the directory the symlink is in (so that groupOfProgrammers can get a complete directory listing there), but turns all permission bits off for the same target of the symlink.

I need to transfer a large number of files from an FTP server to a new server. There could be thousands of files so I would like to limit it to files that were uploaded in the last three months - is that possible and if so how?
Also is it possible to find out how big the download is likely to be before you start the actually download?
Thanks

You can use lftp for that, utilizing its mirror command. Here's a snip from the manpage:
mirror [OPTS] [source [target]]
Mirror specified source directory to local target directory. If target
directory ends with a slash, the source base name is appended to
target directory name. Source and/or target can be URLs pointing to
directories.
[cut...]
-N, --newer-than=SPEC download only files newer than specified time
--on-change=CMD execute the command if anything has been changed
--older-than=SPEC download only files older than specified time
[...]
Definitely have a look at the manual, as there are really many useful options to mirror - like --allow-chown, --allow-suid or --parallel[=N] for example. Lftp also works with other access protocols, like sftp, fish or http(s).

I've created a user called "ftp-acc" and limited it to a single directory using VSFTPD. When I login to the account in Filezilla using FTP, it is successfully restricted to a single directory.
However, when logging in with the same credentials using SFTP, the user can access other directories as well.
How can I disable SFTP for the user "ftp-acc"?
|
First point , FTP and SFTP both are different. FTP normal file transfer protocol but SFTP is secure file transfer protocol and this service is from SSH not a stand alone service.
If you want to disable SFTP for one user then open sshd_config file in server(machine you are trying to access) and
DenyUsers ftp-acc
and then restart sshd service with
service sshd restart

I want to download multiple files from a FTP server (Android app). I used FTP client and mget command (Ubuntu Terminal). But it prompts me to enter y or n for every file that I want to download.

What's the difference between anonymous and guest logins in vsftpd?
Both can be enabled/disabled:

Both are mapped to a different username:

This quote describes it:
guest_enable
If enabled, all non-anonymous logins are classed as "guest" logins. A guest login is remapped to the user specified in the
guest_username setting.
Anonymous access is intended mainly for providing access to public files to everybody.
Guests need a login/password. Guest feature limits the access only to a group of people (e.g. company employees, or registered customers).

I need to transfer files from my ftp to another, is there any tool to put two access and I transfer from one to another without downloading the files to my machine?
|
You can use a client that supports the FXP protocol, as described in one of the answers from this webmaster.stackexchange.com Q&A: How can I transfer files from one server to another server using FTP
The following is from the SmartFTP Knowledge base:
excerpt
What Is FXP?
FXP stands for File eXchange Protocol. It lets you copy files from one
FTP-server to another using an FXP-client. Normally you transfer files
using the FTP protocol between your machine and a FTP-server, and the
maximum transfer speed depends on the speed of your Internet
connection (e.g. 56k, cable or T1). When transferring files between
two remote servers using an FXP client, the maximum transfer speed
does not depend on your connection but only on the connection between
the two servers, which is usually much faster than your own
connection. Because it is a direct connection you will not be able to
see the progress or the transfer speed of the files.
2 such clients that support this are SmartFTP and CuteFTP.
excerpt
Restrictions
Both FTP servers must support FXP and have it enabled. Please consult with the server administrator since most FTP servers do not
support FXP, or have FXP disabled due to potential security risks.
One server has to support PASV mode and the other server must allow PORT commands from a foreign address. The client logs in to both
servers and then it arranges for a file transfer by telling one server
that it will be a passive transfer and the other that it will be an
active transfer, see example.
excerpt
Example
The FTP client tells the destination FTP server to listen for a
connection by sending a "PASV" command. The source FTP server connects
to the data port reported by the destination server (after a
successful PASV command). The client then passes the address/port in a
"PORT" command to the destination server. Thus all the data goes
directly from the source to the destination FTP server. Both servers
only report status messages on fail/success to the FTP client. You can
transfer files from one remote server to another using SmartFTP by
opening a remote server in each window and then dragging and dropping.

I'd been seeing that * isn't interpreted on ftp or lftp. Suppose I want to change a directory from current to say ./japan
In ftp> of lftp>, if I give:
$ cd jap*
it would show this error:
No such file or directory
So, I'm forced to give the complete name:
$ cd japan
EDIT #1
@thomas, @gold: Thank you for your valuable information. As * isn't interpreted with all commands (like cd), is there any way so that I can get away from typing every time the complete file name.

If you're using lftp you can use the Tab key to do path completion similar to the same method used when in a shell such as Bash or Zsh.
If you continue to hit Tab as you type it will complete as much of what matches. You can continue to type additional characters from the results of what's left that matches what you're typed thus far.
Example
Initially after connecting to an SFTP server.
lftp me@sftpserver:~> pwd
sftp://me@sftpserver/home/me
It I type cd u and then hit Tab one time it will complete this:
lftp me@sftpserver:~> cd upload/
If I hit it a 2nd time:
lftp me@sftpserver:~> cd upload/
2011-07-12/ a/
If I type a 2 and hit Tab another time it will complete like this:
lftp me@sftpserver:~> cd upload/2011-07-12/
At which point if you hit Enter it will run the above cd command.

I have this folder full of files.
Once per day, I want the newest of the files to be FTPed automatically to a file server.
|
Make a short script, get the filename via this line:
newestfilename=`ls -t $dir| head -1`
(assuming $dir is the directory you're interested in), then feed $filename to your FTP command, and of course, cron this script to run once a day.
If you have ncftp, you can use the following command to ftp the file:
ncftpput -Uftpuser -Pftppasswd ftphost /remote/path $dir/$newestfilename
Without ncftp, this may work:
ftp -u ftp://username:[email protected]/path/to/remote_file $dir/$newestfilename

You can use curlftpfs and rsync to accomplish what you want.
curlftpfs is a FUSE filesystem that will let you mount a remote ftp location as a normal filesystem. Once it's mounted, you can use rsync to sync the mount with a local copy.

I'm on CentOS v6.4 and using its native FTP Server, which i suppose is sftp. (Am i right?) Now i can use FTP well. But i need to log the actions taken by Users.
Logs for the actions, such us, who logged in, who modified which files, who deleted which files .. etc the basically important actions, you know.
So my simple questions would be:
Where & how can i access/check the FTP Logs from Server, please?
Can it even be done with default SFTP? (Do i need vsftpd?)
In short words, what is the best & simplest way to get the FTP Logging, please?

You can log sftp, try this:
In /etc/ssh/sshd_config file, change this line:
Subsystem sftp /usr/libexec/openssh/sftp-server
to:
Subsystem sftp /usr/libexec/openssh/sftp-server -l INFO -f AUTH
Then config syslog log facility AUTH to your file. In Centos 6. edit /etc/rsyslog.conf, add this line:
auth.* /var/log/sftp.log
After making these changes reload (kill -HUP) or restart sshd and restart rsyslog for them to take effect.

First of all: Why I'm trying this? Because we need to download some files AND rename to shorten ones with date "stamps". The remote files have really huge filenames and it's not an option to change(isn't our ftp).
I'm trying to make a bulk download and rename of some files in a remote ftp server, without having to open one ftp connection to each file I have to download. So far, i could achieve renaming and download on-the-fly with nmap ftp command, renaming every file that starts with "N" and ends with ".TXT" to "N_date_time_stamp.TXT"
ftp -niv $url << FTP_COMMAND
user $user $password
cd $remotedir
nmap N*.TXT N_`date "+%H%M%N"`.TXT
mget N*
bye
FTP_COMMAND
The problem is: nmap keeps the same %N value to all files passed to mget, and it should change on every download to the current nanosecond value:

Is there a way to update the nmap on each download?

Well, i did some sort of mixed implementation, based on the answers of Stephane and slm. I couldn't use zsh because is a production server and installing a new shell is not an option, so, i used lftp that was installed:
Explanation: On the first here_docs(FTPLISTGET) connect on the ftp server and list the files(nlist). If the listing was successfull( if [ $? -eq 0 ] ) download, one file by one renaming with the current date on the format year,month,day,hour,minute,nanosecond). Some ftps are blazing fast, and saving the second could overwrite the files.
exec_ftp(){
# LIST
LIST_FTP=`lftp $protocol://$url << FTPLISTGET
user $user $pass
nlist
bye
FTPLISTGET`
# Check if list is not empty, proceed...
if [ $? -eq 0 ]; then
echo "$LIST_FTP" | while read file
do
DEST="N_$(date +%Y%m%d%H%M%N).TXT"
lftp $protocol://$url <<-DOWNLOAD
user $user $pass
cd $remotedir
get $file -o /home/user/$DEST
rm $file
bye
DOWNLOAD
echo "Done in $(date +%d/%m/%Y-%T)" >> /var/log/transfer_ftp.log
done
# If listing is not possible,
else
echo "FTP: $url user: $user - Cant reach host, or wrong credentials" >> /var/log/transfer_ftp_error.log
fi
}
Edit 1: Changed backticks to $(...) as suggested by slm, and added the variable $protocol. Why? Because lftp can download and automate sftp and ftps, and this will be pretty good to us :)

I just installed vsftpd according to these directions.
I am trying to get ftp working on my Ubuntu box that is using Amazon AWS. When I first tried this directions, it did not work. I was trying to connect via FileZilla and Winscp from my windows machine to my Ubuntu server.
When it failed, I tried adding these options to my /etc/vsftpd.conf file. Specifically:
pasv_enable=YES
pasv_min_port=64000
pasv_max_port=64321
port_enable=YES
pasv_address=<your-publicly-resolvable-host-name>
pasv_addr_resolve=YES <or> NO
This did not help. Finally, what did work was switching winSCP into "Active Mode". My question is: What do those different parameters mean? I am assuming that in is to enable passive mode, and to help guide the ports used for passive mode, but I am not sure what port_enable pasv_address and pasv_addr_resolve do.
Also, now that I am using active mode, do I need to have any of those entries? Thank you
|
There is (obviously) manual page for vsftpd.conf, which is always a good place to start.
TLDR version: They should be needed only for passive mode of FTP.
pasv_enable
Set to NO if you want to disallow the PASV method of obtaining a data connection.
Default: YES
pasv_address
Use this option to override the IP address that vsftpd will advertise in response to the PASV command. Provide a numeric IP address, unless pasv_addr_resolve is enabled, in which case you can provide a hostname which will be DNS resolved for you at startup.
Default: (none - the address is taken from the incoming connected socket)
pasv_addr_resolve
Set to YES if you want to use a hostname (as opposed to IP address) in the pasv_address option.
Default: NO

|
Adding --disable-epsv switch fixed the problem.
A little explanation:
I just went through many hours of trying to figure out wierd FTP
problems. The way that the problem presented was that after login,
when the FTP client attempted a directory listing (or any other
command), it would just hang. EPSV is "extended passive mode", and is
a newer extension to FTP's historical passive mode (PASV) ... most
recent FTP clients attempt EPSV first, and then only use the
traditional PASV if it fails. ... if the firewall is blocking EPSV,
the client will think that the command is successful [and keep waiting for response].

I have some folder, need anybodies php scripts can create sub folder/files and unlink files.
I do sudo chown -R apache:apache /var/www/public_html/a
But after that, my ftp user cannot upload files in that folder.
And I do sudo chown -R yulichika:users /var/www/public_html/a
that ftp can access the folder, but anybodies php scripts with a wrong permisson.
I do not want set the whole folder with 0777, so how to chown 2 users with the permission to operate the same folder? thanks.
|
You can use access control lists commands.
First set owner apache to the directory
sudo chown -R apache:apache /var/www/public_html/a
Now set acl so that ftp user can upload folders.
FOR USER
sudo setfacl -R -m u:yulichika:rwx /var/www/public_html/a
FOR GROUP
sudo setfacl -R -m g:users:rwx /var/www/public_html/a
Hope this will solve your problem.

There are three main possibilities attached to that error code. You either don't have permission to upload to that directory, the disk on the server is full, or uploading the file would exceed your user's disk quota.
Ftp 4xx error codes are "Transient Negative Completion reply" codes. In other words, these error codes are returned when the server fails to do something. Specifically, error code 451 indicates that the server could not write to a file.
If it is true that you are able to create files of zero size in the remote directory, then the possibility of a permission error is most likely ruled out.
If you can contact the server's administrator, you should be able to determine the exact problem.

We have 2 linux RH servers, that were configured the same way. Same OS version, same ftp client, etc.
The ftp client that we had installed is located in this website.
http://rpm.pbone.net/index.php3/stat/4/idpl/20810117/dir/scientific_linux_6/com/ftp-0.17-53.el6.x86_64.rpm.html
The permissions were already set up equally at a firewall level, for both servers. Both are on the same vlan 10.240.194.x/23
We have server A and B.
Server A connects to the ftp server withouth issues, we just have to set it up in active connection.
Server B does connect as well and we set it up in active mode. But when we try to list files/directories, find current dir location, or upload/download files we can't. So far the only thing we are able to do, is change to another directory.
Everytime we try, to do at least a simple ls,pwd we get this msg
200 PORT command successful.
150 Opening ASCII mode data connection. #It gets stuck here for a while.
500 Command not understood.
As far as I understand, that ftp client, which is installed in both servers, doesn't have anything to be changed or configured.
Does anyone has an idea of what could be check/change to make the other server work. Sadly the FTP server, is not owned by our company. I tried to do some search, but haven't been lucky.
Any help is appreciated.

You have to do FTP in passive mode and not active mode.
If using a text client, you have to use the command:
PASV
If using another piece of software, you will have to find the menu for PASSIVE mode transmission.

if I connect to my ftp server using ftp command i'll have only a prompt waiting for me to enter one of the available commands listed using help, I am not newbie that much to believe those commands are wrappers of more sub-layered protocol ftp instructions such as 'MKD', 'SMNT', 'NLST', (and more).
I would like to know if it's possible to use native ftp commands using the ftp originally installed bash tool; And if not, is there some powerful tools to achieve that ?

Can I use ProFTPd without using a chroot jail (thereby preventing access to anything outside of the FTP root)? I have a requirement to have symlinks in my FTP source that point to locations outside of the directory where I root my FTP service.
All of the docs and discussion I've read on ProFTPd talk about how to use the chroot functionality (even within StackExchange), but I'm wondering if I can bypass using that and use a different method to serve my FTP root. Since the symlinks must remain as symlinks, mounting the directories as a way of bypassing the chroot restriction (the clever "solution" to the problem) does not work.
|
ProFTPD has the mod_vroot module for this purpose. You can compile this module into ProFTPD yourself or install it if your repositories have it (apt-get install proftpd-mod-vroot for certain Debian repositories).
mod_vroot allows a user to configure a "virtual chroot", setting the DefaultRoot directive (the initial/root directory for a session; ProFTPD would chroot to this directory without mod_vroot), but allowing symbolic links to point outside of the DefaultRoot path. mod_vroot also supports the VRootServerRoot directive, to which ProFTPD will perform a real chroot, meaning that symlinks can point outside of the DefaultRoot, but must target locations within the VRootServerRoot path.
Example config:
<IfModule mod_vroot.c>
VRootEngine on
VRootServerRoot /usr/share/ # Symlinks can only point to location within /usr/share/
VRootOptions allowSymlinks
DefaultRoot /usr/share/ftproot/
</IfModule>

A macdef directive, like the others (login, password, etc.), only applies to the machine-headed stanza that it's in. As far as I know, putting a macdef directive before the first machine stanza has no effect, and there's no way to have a macro available before the open command is executed.
Your macro will work if you open a connection to the site first:
$ ftp ftp.nyxdata.com
ftp> $download_nyse_index
To script a full FTP session, pass input to the ftp command.
ftp ftp.nyxdata.com <<EOF
cd /OpenBook/SymbolMapping
bin
get SymbolMap.xml /tmp/SymbolMap.xml
quit
EOF
If you're doing something this simple, use wget or curl. If you don't want the password to be on the command line, you can put in in ~/.netrc; wget reads it by default, and curl reads it if you pass the -n option.
wget -O /tmp/SymbolMap.xml ftp://ftp.nyxdata.com/OpenBook/SymbolMapping/SymbolMap.xml

Currently running CentOS 6.5 with vsftpd.
I would like to explain my process and then have the proper process explained back to me from scratch which I believe will solve my issue.
I am currently able to log into my server via FTP from my "root" user account, but I understand that is bad practice. So what I need to do is create another local user/virtual user (I really do not know) to be able to access via FTP the "/var/www" directory.
(I'm simply needing to get to the point were I can begin uploading web files, as I'm a web programmer, not a system administrator -- but I was so pleasantly surprise with a dedicated server to work with.)
Initially I created a Local User, but was only able to FTP the "home" user directory. So I next tries unjailing that user via CHROOT (vsftpd.conf). That worked sort of; the parent directories were visible, but upon navigating up to them via FTP everything disappeared (possibly an issue with permissions, I don't know). Next I tried rejailing the Local User and then modifying its "home" directory from "/home/" to "/var/www". After doing attempting that, I FTP'd in and then could not see anything, so another fail. I've since returned the user's "home" directory back to "/home/" and crawl over to SOF confused as hell.

First of all I'd create a symlink between /var/www/ and my home
what this does is, when you land into /home/usr you can go to /home/usr/www and it will redirect you to /var/www
for instance.
cd /home/usr
sudo ln -s /var/www www
perform a ls -lrt on /var/www
ls -lrt /var/www/
now make sure your usr is part of group that owns www.
this tells you who owns that directory, if it's root:root, it's a bad practice, depending on your distro, it could be www-data or apache etc..
cat /etc/group | grep -e apache -e http -e ftp -e www
apache:x:48:
if usr is at the end of the result your usr is part of that group
if you don't have a group that owns www and it's root:root
create one
groupadd www-data
assuming that group is www-data
sudo adduser usr www-data
now make your user the boss of www
sudo chown usr:www-data -R /var/www
set the right permissions of www
sudo chmod 0755 -R /var/www
sudo chmod g+s -R /var/www

My question is twofold. I need to somehow re-enable telnet and/or ssh in a device where I currently only have root ftp access. Also, if I am going about this wrong, please let me know. Details to follow...
Background
I have a special development board running Arm Linux with the 2.6 kernel. (The device is the 9G45, but that is not really relevant to my question.) I was happily monkeying around with settings and such, I somehow caused sshd to stop working.
Upon restart, ssh connections were refused.
Troubleshooting
I have found that Lighttpd is working and serving up pages. This confirms that both network and some of the initialization works.
I have found that vsftpd is functioning and I do have root access here.
I can connect to telnet, but the documented default user named "guest" is not working. Neither is root.
Using ftp, I determined that the sshd pid file is not present, so I assume it is not running.
Unfortunately, connectiong via serial did not seem to work, but I have a support ticket out with the manufaturer, so maybe they will answer me.
Possible solutions (needs refining)
I figure that I may be able to get in through the root ftp access, monkey with an init script or something else, then possibly gain telnet access (or maybe set sshd to run later in the boot process).
I am not really sure where to go from here. If someone could build on my possible solution or propose a new one it would be greatly appreciated.
|
Fixing files
When you're limited to ftp access only on a system your only real option is to get/put files onto the device. But this turns out to often be all you need to "break" into a system. The approach you're going to want to take is to pull a file down to your local system, edit this file, and then put it back.
/etc/passwd & /etc/shadow
The files you'll want to start with are the /etc/passwd and /etc/shadow files. If you grab these you can then make sure that the user/name passwords are all set in there.
A big hint is that since you know root's password, you can copy the password string for this user from /etc/shadow to any other corresponding user so that you now know that user's password as well (it'll be the same one that root uses).
ssh access
Going beyond the accounts the same approach can be used to get sshd working as well. The config file for sshd is typically in this directory, /etc/ssh/sshd_config. You'll want to make sure that this file is in a usable state so that sshd,the daemon, can come up and allow you to login. NOTE: It's often the case that user root is not allowed to ssh into systems, so you might need to temporarily allow this, just to gain ssh access to the system. You can turn it off afterwards.
sshd service
You'll also need to make sure that sshd the service starts up when the system boots. This one is a little trickier. Given you're using Linux 2.6 I'm going to assume that your system is using /etc/init.d for the various services that are suppose to run on your system. You can create links to the files in /etc/init.d under /etc/rc3.d such that the sshd service starts up when the system reboots. Something like this:
$ ls -l /etc/rc3.d/ |grep ssh
lrwxrwxrwx 1 root root 14 Aug 10 2011 S55sshd -> ../init.d/sshd
starting the service
Getting this service to start is a little trickier, you'll either have to reboot (risky since you might lose ftp access) or if the system has cron or at services running you could add a task to either of these that would start the service at a specific point in time, say 1 minute from now.
Everything else
Once you have sshd access restored you can fix telnet and anything else from that shell, so I won't go any further and discuss these since they are beyond the score of restoring access with ssh working.

So I have an AIX 6 server. How can I check if FXP is enabled on the FTPD or not?
|
According to IBM's AIX documentation for ftpd, there is a -ff flag which:
Disables checking for both a privileged port and an IP address that matches the one used for the control connection when the client requests the server to connect back to a specific client port. Using this flag enables the client to request that the server send data to an alternate host or interface. By default, ftpd does not allow this action as a security precaution.
This seems as though it would allow FXP, especially since according to Wikipedia:
Although FXP is often considered a distinct protocol, it is in fact merely an extension of the FTP protocol and is specified in RFC 959
If that is the case, FXP is disabled by default since the option is not specified in inetd.conf. You can confirm by adding the flag and trying to initiate an FXP transfer. The transfer should only be allowed when the flag is in place.

I am setting up SFTP access to one of my machines running Linux with the Dropbear SSH server. When I SFTP onto the machine remotely, I can see the entire filesystem on it, even if I might not have write access.
How to I control what directories a user can see when connecting to my machine via SFTP? For example, what if I only want to make one directory, e.g. /ftp/, visible and accessible?
Thanks.
|
I believe you'll need to run your dropbear ssh server inside a chroot'd jail if you want to restrict it to certain directories.
If you were using a recent OpenSSH, I'd suggest using the ChrootDirectory setting in your sshd_config. It doesn't appear as though dropbear has a similar parameter, so you'll have to do it manually.

done < $CREDENTIALS_FILE
The script hangs in some cases like when the password updated in the CREDENTIALS_FILE is not matching (because of password change in the source server from where file is being fetched). In such case, the password entry gets two responses (yes and $pass1) and then hangs for third password prompt since first two are wrong. Here, it hangs for a very long time (in some cases it doesn't which is another confusion i have why it doesn't happen in those cases).
Anyways, whatever the case maybe i want to make the SFTP session timeout quickly if any of such scenario happens. How do i make the session to get a timeout quickly if the passwords do not match at all? I am already using a timeout. For a normal session, my script takes a max of 30-35 seconds to connect to the servers and FTP the files to the local machine.
Could anyone please provide some pointers regarding how to fix this issue?

You can add to the sftp command the option
-o NumberOfPasswordPrompts=1
to stop it asking twice for passwords. You might usefully also try
-o ConnectTimeout=20
-o ConnectionAttempts=1

I have a .netrc with the following format in a directory using a bash terminal on OSX:
machine m...
login l...
password p...
I have chowned and cmoded the file like this, as suggested in this help file
$ chown myusername .netrc
$ chmod +600 .netrc
When I am in the directory, I issue the following command:
$ftp m...
Based on this tutorial (see section "useage of the .netrc") it seems like unix should automatically detect that there is a .netrc file in the directory when I type ftp m.., see that the .netrc gives credentials for machine . and pass them along to ftp.
This is not happening. Instead, I see this output
Connected to server.domain.com
220 Microsoft FTP Service
Name (file.server.domain.com:My_OSX_Username): #I would expect it would pull my username off the .netrc file
Am I using the .netrc file incorrectly?
|
Yes, in general the .netrc file should just work as you've described. It might be getting blocked by your FTP client not supporting it (perhaps it was explicitly built without this feature enabled). This would likely be done since this method of storing usernames/passwords is inherently insecure and should likely not be used.
Checking with strace
You can always confirm what an application is doing by tracing it using the command line tool, strace.
$ strace -s 2000 -o ftp.log ftp m
After doing this you can analyze the log file, ftp.log to see if your ftp client is attempting to read the file .netrc. If it's working correctly you'll see this type of output in the log.
setsockopt(3, SOL_SOCKET, SO_OOBINLINE, [1], 4) = 0
open("/home/saml/.netrc", O_RDONLY) = 4
uname({sys="Linux", node="greeneggs.bubba.net", ...}) = 0
fstat(4, {st_mode=S_IFREG|0600, st_size=47, ...}) = 0
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f4898b85000
read(4, "machine ftp.somedom.org\n\tlogin sam\n\tpassword blah\n", 4096) = 47
fstat(4, {st_mode=S_IFREG|0600, st_size=47, ...}) = 0
read(4, "", 4096) = 0
close(4) = 0
NOTE: In the above I'm connecting to ftp.somedom.org as user "sam" using password "blah". You can see that it read from my .netrc file.
ftp man page
If you take a look at the ftp man page there is this switch that's mentioned in my version:
-n Restrains ftp from attempting “auto-login” upon initial connection.
If auto-login is enabled, ftp will check the .netrc (see netrc(5))
file in the user's home directory for an entry describing an account
on the remote machine. If no entry exists, ftp will prompt for the
remote machine login name (default is the user identity on the local
machine), and, if necessary, prompt for a password and an account
with which to login.
open host [port]
Establish a connection to the specified host FTP server. An optional
port number may be supplied, in which case, ftp will attempt to
contact an FTP server at that port. If the auto-login option is on
(default), ftp will also attempt to automatically log the user in to
the FTP server (see below).

I have recently installed DD-WRT on my D-Link DIR-615 router (rev. D3). Everything seems fine but I cannot connect to some (most) FTP servers anymore. Any ideas what can cause this issue?

Passive/active doesn't make a difference.
I've discovered something interesting. I've set up a port range forwarding 1024-65535 | Both | 192.168.1.131 for the testing purposes. After that I have enabled or disabled (it doesn't really matters it seems) the UPnP service and it let me connect to FTP but just for a few seconds.

This is an old topic, but someone might still find my solution useful: update your firmare. DD-WRT provides updated versions and the last one I could find here http://dd-wrt.com/site/support/other-downloads?path=others%2Feko%2FBrainSlayer-V24-preSP2%2F works. I can finally use FTP.

I have some automated scripts which perform FTP uploads among other things. I'm wondering what level of error checking I should conduct once these uploads have finished executing.
Could anything go wrong uploading a file when it reports "226 Transfer complete" which would warrant extra tests, besides checking for this string in the log, to check if a file was successfully uploaded?
|
No, it does not. 226 can also occur on various conditions where this would not be true (ABORT for one). See RFC 959.

I can do tcpdumps with this command:
tcpdump -w `date +%F-%Hh-%Mm-%Ss-%N`.pcap src 10.10.10.10 or dst 10.10.10.10
Q: I have an FTP server with username: FTPUSER and password FTPPASSWORD. How can I upload the tcpdump in "real time" I mean I don't have a too big storage to store the dumps, so I need to upload it to a place what I can only reach via FTP. Can I "pipe" somehow the output of the tcpdump to an ftp client that uploads it? [I need to preserve the filenames too: "date +%F-%Hh-%Mm-%Ss-%N.pcap"]
so I'm searching for a solution that doesn't store any tcpdumps locally, rather it uploads the dumps in "real-time".
The OS is OpenWrt 10.03 - the router where the tcpdump runs. [4MB flash on the router, that's why I can't store them locally.]
UPDATE2: there is no SSH connection to the FTP server, just FTP [and FTPES, but that doesn't matter now I think]
|
install curlftpfs
opkg update; opkg install curlftpfs
then create a script that will run after every boot of the router
vi /etc/rc.d/S99tcpdump
the content of S99tcpdump
#!/bin/ash
mkdir -p /dev/shm/something
curlftpfs FTPUSERNAMEHERE:[email protected] /dev/shm/something/
tcpdump -i wlan0 -s 0 dst 192.168.1.200 or src 192.168.1.200 -w "/dev/shm/something/tcpdump-`date +%F-%Hh-%Mm-%Ss`.pcap" &
make it executable
chmod +x /etc/rc.d/S99tcpdump
reboot router, enjoy.
p.s.: looks like "-s 0" is needed because there could be messages like: "packet size limited when capturing, etc." - when loading the .pcap files in wireshark
p.s.2: make sure the time is correct because if not, the output filename could be wrong..

Ok, let's say I am responsible for old application that I don't really know the details of, I am trying to secure my server, and someone suggested to forbid the 21 port that used for FTP.
But I am not sure which programs are running and use FTP on a day to day basis.
Say I don't have the solution to install the tools I want on the server or on the Network. What are my solutions?
Should I cut the 21 port and see what transfers are blocked by the firewall?
Is there a place on the AIX server where I should go and look to see the list of accessed and accessing servers via this port? If I have the IP of the server(s) and the file names, I will be able to track the program doing it. So is there a log file for FTP?
Edit:
a) inetd is active and ftp is in it (thanks @JeffSchaller)
b) I am trying to know incoming and outgoing traffic on this port - with the commands that were performed (if possible). In other words, my goal is to know
What commands have been performed on the local FTP server
What commands have been performed by the local FTP client to other servers
Any suggestion welcome.
|
What commands have been performed on the local FTP server?
To enable FTP logging on an AIX system, you need to reconfigure FTP (being called by inetd in your case) to send debug logs to syslog and to configure syslog to save those logs to a file.
Edit /etc/inetd.conf and add -d to the end of the ftpd line:
ftp stream tcp6 nowait root /usr/sbin/ftpd ftpd -d
Refresh inetd: refresh -s inetd
Edit /etc/syslog.conf and add a line for daemon.debug to save the logs somewhere:
daemon.debug /var/log/ftp.log
Create a file for syslog to write to: touch /var/log/ftp.log
Refresh syslogd: refresh -s syslogd
Syslog will send any daemon's logs to this file, so you'll want to filter it down with grep, perhaps: grep 'daemon:debug ftpd' /var/log/ftp.log.
Commands that were sent via FTP will be logged with the string command:; here's a sample:
May 18 10:13:35 ftpserver daemon:debug ftpd[3932700]: command: USER username-here^M
May 18 10:13:35 ftpserver daemon:debug ftpd[3932700]: <--- 331
May 18 10:13:35 ftpserver daemon:debug ftpd[3932700]: Password required for username-here.

May 18 10:13:42 ftpserver daemon:debug ftpd[3932700]: Last login: Fri May 18 10:13:02 EDT 2018 on ftp from ftpclient.example.com
May 18 10:13:43 ftpserver daemon:debug ftpd[3932700]: <--- 230
May 18 10:13:43 ftpserver daemon:debug ftpd[3932700]: User username-here logged in.
May 18 10:13:43 ftpserver daemon:debug ftpd[3932700]: command: PORT 10,1,1,1,229,54^M
May 18 10:13:43 ftpserver daemon:debug ftpd[3932700]: <--- 200
May 18 10:13:43 ftpserver daemon:debug ftpd[3932700]: PORT command successful.
May 18 10:13:43 ftpserver daemon:debug ftpd[3932700]: command: LIST^M
May 18 10:13:43 ftpserver daemon:debug ftpd[3932700]: <--- 150
May 18 10:13:43 ftpserver daemon:debug ftpd[3932700]: Opening data connection for /bin/ls.
May 18 10:13:43 ftpserver daemon:debug ftpd[3932700]: <--- 226
May 18 10:13:43 ftpserver daemon:debug ftpd[3932700]: Transfer complete.
Yes, those Control-M's appear as such in the logs!
What commands have been performed by the local FTP client to other servers?
Since applications could perform their own FTP actions, it'd be difficult to wrap every possible client program (such as /usr/bin/ftp) to catch this. The best bet is to configure the remote FTP server to log the commands, just as we did above. Second-best would be to configure the AIX firewall to allow-and-log traffic destined for port 21.
Ensure you have the ipsec fileset installed:
lslpp -L bos.net.ipsec.rte; echo $?
It should show a fileset listed with a return code of 0, and not:
lslpp: 0504-132 Fileset bos.net.ipsec.rte not installed.
Ensure the ipsec devices are enabled:
lsdev -l ipsec_v4
You should get one line back saying "Available", not "Defined" or no lines back at all.
If there was no output or the device was "Defined":
run smitty ipsec4
choose Start/Stop IP Security,
choose Start IP Security,
leave the defaults at Now and After Reboot and Deny All Non_Secure = no
hit Enter.
The ipsec device_v4 should now show as "Available".
Create a logging file with: touch /var/log/ipsec.log.
Update syslog:
echo "local4.debug /var/log/ipsec.log rotate size 100k files 4" >> /etc/syslog.conf
refresh -s syslogd
Add a rule to allow and log traffic destined for port 21:
# -v 4 == IPv4
# -n 2 == add this after the first rule
# -a P == permit
# -O eq == destination port *equals* 21
# -P 21 == destination port 21
# -w O == outbound connections; change this to “B” to log in both directions
# -c tcp == TCP protocol
# -s, -m, -d, -M = source/dest IP & mask (any)
# -l Y = Log it
# -r L = applies only to packets destined or originated from the local host
genfilt -v 4 -n 2 -a P -O eq -P 21 -w O -c tcp -s 0.0.0.0 -m 0.0.0.0 -d 0.0.0.0 -M 0.0.0.0 -l Y -r L -D “allow and log port 21 traffic”
Start logging:
mkfilt -g start
Activate the ruleset:
mkfilt -u
Wait for outbound FTP connections to occur, then:
grep ipsec_logd /var/log/ipsec.log | grep DP:21
You'll see source and destination IPs for outbound FTP connections along with the timestamps, such as:
May 18 11:29:40 localhost local4:info ipsec_logd: #:0 R:p O:10.1.1.1 S:10.1.1.1 D:10.2.2.2 P:tcp SP:55091 DP:21 R:l I:en0 F:n T:0 L:0
It doesn't log the content (commands) of the FTP session, but you'll have timestamps and destinations. Note that every packet of each FTP connection is logged!

I want to be able to store the login details all of my remote FTP accounts in one place, securely. Then I'd like clients like autofs/curlftpfs, Filezilla, etc to use this one store of passwords. I'm not interested in GUI-dependent solutions. Is this possible somehow?
|
Ideally those would be SFTP accounts, using SSH public key authentication rather than passwords. You'd gain both security and convenience. But let's assume you don't have a choice of not using FTP with passwords.
You could store the passwords (the .netrc file) on an encrypted filesystem and mount that filesystem only when you want to access it. A simple way to create an encrypted directory tree is encfs. Setup:
# install encfs, e.g. apt-get install encfs
mkdir ~/.passwords.d
encfs ~/.passwords.encfs ~/.passwords.d
mv ~/.netrc ~/.passwords.d
ln -s .passwords.d/.netrc ~
fusermount -u ~/.passwords.d
Daily use:
encfs ~/.passwords.encfs ~/.passwords.d
ftp …
fusermount -u ~/.passwords.d

When downloading /var/log/apache2/other_vhosts_access.log (100 MB) from a distant server to my local computer via SFTP, I noticed that the network transfer was not compressed.
Indeed similar compressed files are ~ 10 MB and it would have taken 1/10th of the downloading time I observed.
Is there an option in SSH/SFTP settings to auto-compress file transfer to reduce bandwidth and uploading/downloading time?
(The server has Ubuntu and the local computer is using Win + WinSCP).
|
On WinSCP, transport compression can be enabled in the SSH page on the Advanced Site Settings dialog:
For an OpenSSH command line client, the -C option to sftp (passed through as the -C option to ssh) provides transport compression for the session.

I'm using a shell script which executes lftp mirror --reverse to upload files and directories to a remote server. Just before that it removes everything using glob -a rm -r -f *. The problem is, it is not so fast. Whole operation takes couple of minutes, especially the recursive removal. I'm uploading few megabytes of data in a couple of hundred files, but most of them do not change. I'm connecting through FTPS protocol.
Question
How to improve the performance of my script?
I was thinking about uploading only files that are new or were changed locally and at the same time removing the ones from the remote server that are not present on my local machine. Sadly, I don't know if it is possible or how to achieve it.
Whole script:
lftp $host << EOF
user $username $password
cd $destination_directory
glob -a rm -r -f *
mirror --reverse $local_directory .
exit
EOF
|
The solution was at hand. While digging through LFTP manual I found that mirror command has a --delete option which perfectly suits my needs.
--delete
delete files not present at the source ~ LFTP Manual
I changed
glob -a rm -r -f *
mirror --reverse $local_directory .
to
mirror --reverse --delete $local_directory .

<log prefix="ftp fw limit 2/m " level="warning">
<limit value="2/m"/>
</log>
<accept>

I’m using the ftp command line tool and want combine scripted input with user input. With only user input the prompt looks like this:

But when I try to insert some input with a script, like

How can I force ftp (or any cli) to still use the interactive mode?
I would prefer a solution based on standard shell tools.
|
There is a program to interact with interactive command line tools exactly like the ftp example: expect. It is a specialized script shell, extending the on the scripting language tcl.
It is very powerful, but you may get away without learning everything about it. A very useful tool is autoexpect, which can record an interactive session as an expect script. The recorded script is certainly helpful to understand the basics.
A expect script can interact with an interactive program like ftp.
This can be combined with interaction of the user and the interactive program. Using the command interact in an expect script, the control can be given to the user temporarily.
While the user has control, the script still listens for events to take back the control, so practically, both the user and the script are interacting simultaneously with the program.

I have a script that is running on my computer. The script is written in PHP under my XAMP server. It actually is reading some files from a remote FTP server and after processing them writes them back to the same Server. The total estimated time for finishing the process seems to be around 48 hours.
I really need to know if I lock my screen and leave my desk for around two days (a couple hours after the estimated finish time of the process), does the system stall the processes or turn it idle or etc!?!

How do I set/change the default ftp root folder for a specific user? I want to be able to create a developer account that homes to different sites on a development box depending on what is currently being worked on.
EDIT: The server is running Ubuntu and vsftpd.
|
If you specify the user_config_dir in vsftpd.conf, you can set any config option on a per-user basis.
From man vsftpd.conf:
This powerful option allows the override of any config option specified in the manual page, on a per-user basis. Usage is simple, and is best illustrated with an example. If you set user_config_dir to be /etc/vsftpd_user_conf and then log on as the user "chris", then vsftpd will apply the settings in the file /etc/vsftpd_user_conf/chris for the duration of the session.
So, setting local_root in this way to the desired directory changes the FTP root for just that user.

I'm trying to connect to a FTP server behind a firewall that allows incoming connections in the range 6100-6200 only. I have successfully connected to this server using curl like this:
curl --ftp-port :6100-6200 --list-only ftp.server
But I'd like to reproduce the behaviour of this curl command with other clients that are more friendly to use from Python. In principle Linux's ftp, but I'm open to other options if someone suggest a good one. I tried ftplib but it seems that this library does not allow you to select ports; I've tried it unsuccessfully.
Currently I can not make it work with ftp:
230 Login successful.
Remote system type is UNIX.
Using binary mode to transfer files.
ftp> passive
Passive mode on.
ftp> ls
227 Entering Passive Mode (XXX,XXX,XXX,XXX,202,251).
ftp: connect: Connection refused
The same set of commands work from my laptop, therefore it seems clear that the problem is the firewall.
How can I force ftp to negociate a data connection in a port in the range 6100-6200, so emulating the behaviour of curl?
|
When you use FTP in passive mode, the server tells the client which (server-side) data port to use. The well-known FTP protocol includes no way for the client to express requests on which port range to use at the server end. There could be some extensions that could change that, but those are not necessarily widely supported.
In your example, the message
227 Entering Passive Mode (XXX,XXX,XXX,XXX,202,251).
comes directly from the FTP server, as it's telling the client: "I'm listening for a data connection from you at IP address XXX.XXX.XXX.XXX, port 51683" (= 202*256 + 251).
Each TCP connection has two port numbers: a local port number and a remote port number. Usually, an outgoing connection just picks the first free local port in the OS-specified range of ports to be used for outgoing connections, and the remote port is specified according to the service that's being used. In case of passive FTP, the server will pick the remote port according to its configuration and will tell it to the client in the form of a FTP 227 response.
There are generally two ways to handle passive FTP in firewalls:
a) The firewall and the FTP server need both be configured in cooperation to accept/use a specific range of ports for passive FTP data connections, so the server won't even try to select a port the firewall is not going to let through,
or b) the firewall needs to listen in on the FTP command channel traffic, determine the port numbers used for each data connection and dynamically allow passive FTP data connections between the FTP client and server using the port numbers declared on the command channel.
If you are using Linux iptables/netfilter firewall, this is exactly what the protocol-specific conntrack extension module for FTP does. You'll just need to tell it what control connections it's allowed to listen to, since the previous policy of listening on all FTP control connections passing through the firewall system turned out to be exploitable by bad guys, and now such extensions will no longer be used automatically. For details, see this page or this question here on U&L SE.
curl actually uses FTP in passive mode by default, but when you use the --ftp-port option it switches to active mode. From the man page (highlight mine):
-P, --ftp-port
(FTP) Reverses the default initiator/listener roles when connecting with FTP. This option makes curl use active mode. curl then tells the server to connect back to the client's specified address and port, while passive mode asks the server to setup an IP address and port for it to connect to.
Regarding Python and ftplib, note that the question you referred to is more than 10 years old, and there's now a new answer added by Marcus Müller:
Since Python 3.3, ftplib functions that establish connections take a source_addr argument that allows you to do exactly this.

I just finished installing a test web server with Debian Wheezy, apache and phpPgAdmin. I don't know if the default installation includes the ftp server.
How can I check if one is installed?
What do I need to do to start it?
|
There are several different FTP servers packaged within Debian, which you can see via:
apt-cache search ftp-server
One of the most popular servers around is proftpd, and that can be installed upon Debian systems with:
apt-get install proftpd
Once downloaded debconf will ask if you wish to run the server via inetd, or in a standalone fashion. In general you want the latter option.
After the installation the server will be running, and will grant access to all user accounts upon the host.
If you wish to stop the server prior to more configuration you can do so with:
/etc/init.d/proftpd stop
The configuration of proftpd is conducted via the configuration file of /etc/proftpd.conf

I have an ftp server running, and it irregularly generates the latest file. The file is store as:
Home->T22:30:10->new.txt, and the latest one would be (a new folder)
Home->T23:10:25->new.txt (note that this is a new folder with latest time)
I need to implement something (it could be anything, C code, Bash script, etc.) in a Linux machine that pulls the latest file over.
I have looked into two options:
Use libcurl, pass the directory listing, and select the latest file. This is really annoying ass and time-consuming, and I still can't find a easy way to do this.
Use lftp, at initiazation, remove all the files in the server, so that each time when I call lftp to download something, it would be the latest one. (This method is only conceptual and I haven't tried it in real life).
Is there any easier option?
|
An approach that's often convenient is to mount the files, and then access them like you would access ordinary local files. For a server that you access through FTP, you can use CurlFtpFS.
mkdir theserver
curlftpfs theserver.example.com theserver
You'll need to pass the username and password to curlftpfs, either on the command line (which is unsafe as other users on your machine would be able to see them) or in the file ~/.netrc (strongly recommended). Here's a sample netrc line:
machine theserver.example.com login remoteusername password swordfish
Now that you've mounted the FTP server as a directory on your machine, you can use the usual commands such as ls, cp, etc. For example, to copy the file from the directory that comes last in lexicographic order (should be ok if your file names actually contain the date before the time):
set -- theserver/remote/path/T*
eval "last=\${$#}"
cp -p -- "$last/new.txt" "/some/where/local/${last##*/}.txt"
Or to copy the latest file, assuming that the filenames involved don't contain unprintable characters or newlines:
cd theserver/remote/path
last=$(ls -t -- T*/new.txt | head -n 1)
cp -p -- "$last" "/some/where/local/${last%/*}.txt"

Does anyone know which character encoding is used in .netrc? As a German user, I sometimes put umlauts in passwords.
So my question is, are these treated as latin1 or may I assume that I am doing fine encoding the file in UTF-8?
|
There's no applicable standard for .netrc, which started off in the 1980s as a BSD feature. That of course predates UTF-8. However, since there are no standards, you may be using someone's "improvement" which assumes (a) locale-based encoding or (b) UTF-8. Don't count on it.
The password used for ftp is covered by an RFC (again, predating UTF-8), and says the content is ASCII. In section 5.3.2, the relevant part of the BNF is
<password> ::= <string>
<string> ::= <char> | <char><string>
<char> ::= any of the 128 ASCII characters except <CR> and
<LF>
The later RFCs build on RFC 959, but don't change the rules. However, implementers stretch things, so you're able to use Latin1.

I'm trying to access my ftp server through the browser but I am facing an issue.
If I access it using Filezilla, I can see the directories fine. However using a browser I get no directory listing.
I have added this entry to iptables hoping to solve the problem but it didn't change:
-A INPUT -m state --state NEW -m tcp -p tcp --dport 21 -j ACCEPT
|
The simple solution is to switch Filezilla to use passive mode when connecting to that FTP server.
When you connect to FTP you use port 21 which is known as the control channel. This is the connection used to send commands and receive notifications on the results of the commands issued. Note that for file listings (the output to LIST), file transfer (fetching files RETR and putting files STOR) and other operations that actually requires transmission of data, a separate channel known as the the data channel is created. FTP can operate this data channel in either of two modes, active or passive. Both of these refer to how the data channel is established.
You issue a LIST (in active mode)
CLIENT FIREWALL FTP SERVER
_ (port 21) _
__ _ (port 21) |=| ---------- LIST command ---------> |=|
[__]|=| ----- LIST command issued -- > |=| |=|
/::/|_| . |_| <----- FTP server attempts to ---- |_|
`\___ now listening on arbitrary connect and gets denied
port for data channel say 8000 by firewall
In active mode the client advertises an arbitrary listening port it creates and the FTP Server connects to this advertised address and port on the client machine. This is normally where firewalls block the traffic because it is to a random (often changing) high order port number on the client host advertising the FTP data channel. Filezilla defaults to using a port in between 6000 and 7000. If the firewall does not block this connection the output of the LIST command is then transferred over this separate channel.
You issue a LIST (in passive mode)
CLIENT FIREWALL FTP SERVER
_ (port 21) _
__ _ (port 21) |=| ---------- LIST command ---------> |=|
[__]|=| --- LIST command issued -- > |=| |=|
/::/|_| |_| <--- FTP server advertises the --- |_|
listening data port over \___ server with
the control channel listening data
channel
CLIENT FIREWALL FTP SERVER
_ (port 21) _
__ _ <--- open control channel ---> |=| ---- open control channel ----> |=|
[__]|=| |=| |=|
/::/|_| --- client establishes a ----> |_| ---- passive data channel ----> |_|
connection to the connection allowed
advertised data channel by firewall
In passive mode, the roles are reversed, the FTP client issues a PASV command before the LIST command. The FTP Server then creates a listening TCP port and advertises this for the client to connect to to establish the data channel. This is usually allowed by most firewalls (as clients can make connections outbound to any port).
Note that if there is a firewall in between your FTP server and the internet, this firewall ALSO has to be configured to have these ports opened to allow the passive connections. Most FTP servers provide the ability to set the range in which these ports will be advertised and these can be opened to allow those connections.
If you are restricted and have a client that cannot do passive, Filezilla offers the ability (uned Edit -> Settings... -> Connection/FTP/Active Mode to set which ports to use), and you can then add these to your firewall.

As we know we can add folder to user using useradd user -p user_passwd -d /home/ftp/user_dir/ -s /bin/false but how to add folder to existing user, for example /home/ftp/root for root ?
|
Basically you don't add, you change home directory.
usermod -d /home/ftp/root root
if you want to move existing files, use this:
usermod -d /home/ftp/root -m root
Allowing root to access via FTP it not good practice, it's security hole.
Even if this, I would rather recommend to create symlink to target folder from existing directory.

OpenSSH sftp indicates its results using an exit code (what you are going already).
If it returns 0, everything went fine. If it returns 1, there was a problem.
No need to parse the output for an arbitrary message.
Just execute it in a batch mode, so that it aborts on any error. Use -b - switch for that (the - indicates that you still want to provide the commands using stdin, not via a file, which would normally follow the -b).

I have been asked by the data owner to copy a specific folder (and its large amount of subfolders and files) via FTPS to our cloud storage provider. I am using LFTP for that, and the upload worked well until I hit a snag.
There are several folders with multiple files that have the same filename except for case. For example, folder data has the following files:
testfile1.txt, TestFile1.TXT
When I try to upload those via LFTP, I get an error that the file already exists. So for my purposes, I need the files to be case-insensitive before uploading. To address this issue, I would like to use a script that searches the current directory recursively, and moves any case-insensitive duplicates to a subfolder. In my example above, I would want the script to create a subfolder called Duplicates and then move TestFile1.TXT into it. I suppose it's possible that I could have multiple duplicated filenames, so the script should create a Duplicates2 folder for the second duplicated filename, and so on.
Also, I should note that for the few "duplicated" files that I checked, they had differing filesizes. I am not going to make any assumptions about the files being actual duplicates, which is why I want to move them rather than delete them.
|
The bash script below loops through the files in the current directory, looking for duplicate filenames case insensitively. If a match is found, it looks to create a "Duplicates" folder that doesn't exist already, then moves the duplicate file into that directory.
The outer loop is there in order to re-compute the file globs (*) for the loops, in case a file gets moved. The outer loop runs until no files are moved.
#!/bin/bash
changes=1
while [ $changes -gt 0 ]
do
changes=0
for one in *
do
for two in *
do
shopt -u nocasematch
# if it's the exact same filename, skip
[[ "$one" == "$two" ]] && continue
shopt -s nocasematch
# if the file name matches case-insensitively, then mv it
if [[ "$one" == "$two" ]]
then
suffix=
while [ -d Duplicates"${suffix}" ]
do
suffix=$((suffix + 1))
done
mkdir Duplicates"${suffix}"
mv "$two" Duplicates"${suffix}"
changes=1
break
fi
done
done
done
With these sample files:
afile.txt
TestFile1.TXT
TESTfile1.txT
testfile1.txt
A sample run of the script creates:

I can connect to the FTP Server and cd to directories. I cannot run an ls/put/get on there though. When I try on passive mode, I get:

I don't believe this to be an issue particularly with the FTP servers only because I can connect to it via the proxy. Even when I connect to the FTP servers directly, I can run commands on active and passive mode. My questions are:
What else can I look into that can further troubleshoot this?
Is there any further logging configurations I can do that would enhance logging for any kind of TCP requests other than what I currently have?
Is there something configuration wise I am missing in HaProxy (I know that natively HaProxy is an HTTP load balancer but I looked up enough examples where I can configure it to be used as a proxy for FTP servers and I cannot reconfigure the FTP servers to be ran as SFTP)?
|
After much research and some investigation with my colleague on this, this is what was happening:
HaProxy could have been a viable solution. But, the FTP server is configured to force passive mode. HaProxy can be used to proxy FTP connections but there is no real way to configure it to react accordingly to Passive connections. As a result, I was unable to run the ls/get/put (and probably even more) commands!
My Solution was to go to ftp-proxy and configure it. Once I configured ftp-proxy to route traffic to the FTP server (while configuring it to listen to passive connnections), VIOLA! It worked!!

I've created a user 'www' and added it to the 'www-data' group. I've set the home directory of 'www' to /var/www/ also. I would like to use 'www' to transfer files in and out of my web server by FTP
The problem is when I run the command:

However when I run:
sudo chown -R www:www /var/www
..I have full FTP access but get a 'Forbidden' message in my browser.
Any advice on how to get full FTP access including all subfolders would be really appreciated.
|
That means that you already have a www-data user which Apache uses that should have the necessary permissions in /var/www.
The simplest solution would be to use that same user, but you could also assign the www-data group to your new user and make sure the /var/www directory structure allows the group to write to it:
chown -R www-data:www-data /var/www
chmod -R ug+rw /var/www

so I've opened ports 20, 21 as well as 2120-2180 in my NAT (TCP+UDP) and configured proftpd to use this ports for passive communications.
However, trying to connect using FileZilla leads to the following log: (in french, but quite clear actually)
Statut : Résolution de l'adresse de heardrones.com
Statut : Connexion à 93.30.208.56:21...

It times out before even being capable of sending the "PASV" answer !
What could cause this ? The answer to PASV command uses the same port as all other commands (PWD, TYPE ...), so where could it come from ?
Here is the network design :
Server
Proftpd, no iptables, fix IP 192.168.0.13
-> (Wifi)
ISP Box - French ISP (SFR)
port transfer 20,21,22,2120-2180 to 192.168.0.13
-> (optic fiber !)
Internet
I can give Box settings screenshots and proftpd config files if needed. Connecting from LAN/Localhost works perfectly.

FTP is a horrible protocol. It uses two ports -- one for commands, one for data. This makes it notoriously difficult to NAT, since a router would need to parse the command channel and figure out that a second connection is expected for this FTP conversation. Doing so is ugly, but also the only way to make NAT work with FTP.
FTPS encrypts the command channel, thereby making it impossible for any router to inspect the packets and figure out where the data channel is going to be. Obviously that means it won't be able to account for that then; so when your data channel is initiated by the client (as required by PASV) your NATting router won't know what to do with it. It is not possible to fix this, due to the way FTP works.
Just say no to FTP, and use SFTP or something of the sort instead (which transfers files over an SSH tunnel and therefore requires only one TCP connection). Most graphical FTP clients have support for SFTP too, these days.

I need a FTP software that I can use in Debian as well as be able to distribute it when I remaster Debian into my own distro. I need it to be able to do both text and graphical but the text based part needs to be optional for the user.
|
Suggestion:
gFTP
It has both text and graphical interface. See the license, it can be redistributed.

I'm having an issue where when I transfer a Python file to my VPS via FTP and try to run it using ./foo.py I am returned with the error: : No such file or directory.
The error seems to indicate that the file I am trying to execute does not exist. But I can run the program with no problems using python foo.py which leads me to believe that the error actually probably means something else.
At first I thought it could be an issue with the shebang line, so I copied all of the content of the file and pasted it into a new file on the VPS that had not been transferred via FTP. The two files had exactly the same content but when I ran the new file using ./bar.py it ran as expected.
So I've come to the conclusion that this could be an issue with the way that it is transferred. I have switched between ASCII and binary but both of these transfer methods give the same error.
Is it possible to stop this from happening?

This happens when a file contains \r\n as a line terminator instead of \n, since \r is a C0 control code meaning "go to the beginning of the current line".
To fix, run dos2unix foo.py.
Example session:
ben@joyplim /tmp/cr % echo '#!/usr/bin/env python' > foo.py
ben@joyplim /tmp/cr % chmod +x foo.py
ben@joyplim /tmp/cr % ./foo.py
ben@joyplim /tmp/cr % unix2dos foo.py

A vendor has provided these FTP connection params so I can upload some data for them...
Host: host.com
Port: 46800
Protocol: FTP – File Transfer Protocol
Encryption: Require implicit FTP over TLS
Logon Type: Normal
User: [ username ]
Password: [ password ]
It isn't working for me...
$ ftp -p host.com 46800
Connected to host.com
421 Service not available, user interrupt. Connection closed.
ftp>
I suspect the "Require implicit FTP over TLS" param might be the issue? (Maybe?)
TLS isn't mentioned in the FTP man page.
What would be a command that would allow me to connect and upload?
|
The ftp program is for the insecure ftp protocol. Your vendor has specified that you use Implicit FTP over TLS which is a way to encrypt the connection and keep your credentials and data private over the Internet.
Fortunately, there is a program called lftp which understands this protocol.
lftp
open -u [username] ftps://host.com:46800
Password: [enter your password]
ls
[your remote files should be listed]
lftp supports many protocols. This webpage lists them in an easy to read table.

Sure you can use lsof to see what activity is currently taking place on the server. Here's what the output would look like for an idle connection to an SFTP server.

The line that shows me copying the file which witch is wich-dDSr2oxZeAM.mp3 is at the bottom of the output.
When I use SFTP to put a file it shows up like this:
sftp-serv 30268 sam 5r REG 0,19 1933312 9257073 /home/sam/bob.mp3 (mulder:/export/raid1/home/sam)
See a difference?
Me neither, so this method can only tell you whether a file is currently being accessed via a put or get but it cannot distinguish between the two. However this will tell you if the connection is "active" in the sense if there's a file being read/written from/to the SFTP server.
Watching the daemon
I typically use this method when I want to watch the SFTP server.
$ sudo watch "/usr/sbin/lsof -p $(pgrep sftp)"
This will run the lsof command every 2 seconds, "polling" it for any activity.
Multiple connections
If you have more than 1 user connecting at a time, you may need to modify the $(pgrep sftp) and pick a specific PID, if there are multiple sftp-server instances. Also you'll have to identify which user is accessing the files via SFTP. For that though, you can look at the "USER" column in the lsof output.

I know how can I change the umask settings for all the users using ftpd, but how can I change the umask for a given user using FTPD?
AIX/6100-05-02-1034

|
The AIX ftpd doesn't provide per-user umask settings. You can set a global umask value with the -u switch, but neither the command line nor the configuration file allow you to set this on a per-user basis.
Note that you can set the umask, and run chmod, from the client side with SITE commands:

I have a user account rootftp which two people use every once in awhile to ftp into a machine, I believe it is using Solaris and running as a Xerox freeflow print server. The physical machine is a Xerox N-Series, Reg Model D01D, Reg Type D01D001. The two users are running windows 10 if that affects anything. Say we have the two following paths:
Path 1 = /var/somewhere/somewheredeeper
Path 2 = /var/somewhere
When either of the two users use ftp to get to this machine, they start out in the location of path 1. Where/How can I make a change so they start out in Path 2 when they connect through ftp? They need access to Path 2 but if they start out in Path 1 they cannot go up a level higher into Path 1.
I know next to nothing about linux, but I am very slightly familiar with bash and using a terminal. I wasn't able to find this particular information from searching. Thanks for any assistance!
|
Very likely you just need to
update the user's home directory, you could vi /etc/passwd and change /var/somewhere/somewheredeeper to /var/somewhere but you'll then need to
update the permissions on /var/somewhere to have ownership and permissions that allow the rootftp user to ftp to that dir

I'm trying to run tnftpd on OS X, which is NetBSD's FTP server and used to be OS X's FTP server. I built and installed it from Apple's sources. Unfortunately, it seems that I cannot run the server without root privileges. These have been my approaches so far to get the server to work without root privileges:
I've tried changing the port number via the -P option, to ensure
that it uses no privileged ports.
I've tried fiddling with config files, such as ftpd.conf and
ftpusers.
I've also tried the -r option (which disallows root privileges once a
user logs in).
All of these attempts have been to no avail.
Some examples to illustrate my attempts:
$ ftpd -lnD # exit code is 0, but `ps' shows no server running
$ ftpd -lnDr # supposed to drop root privileges, but same as above
$ # let's try running on a different port...
$ ftpd -lnDr -P 50001 # exit code still 0, but no dice
However, if I try something like this (this is a scenario where I have no custom configurations in place):
$ sudo ftpd -lnD
Password:
$ ps aux | grep -i ftpd
root 21998 0.0 0.0 4298888 720 ?? Ss 10:41PM 0:00.00 ftpd -lnD
I have no problems.
How can I run the tnftpd server without root privileges? Is it even possible?
|
According to the man page tnftpd(8)
... The server
uses the TCP protocol and listens at the port specified in the ``ftp''
service specification; see services(5).
and a scan through ftpd.conf(5) shows no obvious means to fiddle with the listen port (as opposed to the data port, which is different) so let's see if we can modify the services file, which is probably a bad idea.
$ sudo perl -i.oops -pe 's/^(ftp\s+21)/${1}21/' /etc/services
$ grep 2121 /etc/services
ftp 2121/udp # File Transfer [Control]
ftp 2121/tcp # File Transfer [Control]
scientia-ssdb 2121/udp # SCIENTIA-SSDB
scientia-ssdb 2121/tcp # SCIENTIA-SSDB
nupaper-ss 12121/tcp # NuPaper Session Service
nupaper-ss 12121/udp # NuPaper Session Service
$
And with this horrible, horrible kluge effected we now start ftpd... (this is on a 10.11.6 system which has ftpd installed by default under /usr/libexec)
$ /usr/libexec/ftpd -lnDr -P 50001
$
And it is running as not-root at the not-21 port:
$ pgrep -lf ftpd
35258 /usr/libexec/ftpd -lnDr -P 50001
$ lsof -P -p 35258 | grep 2121
ftpd 35258 jhqdoe 4u IPv4 0x817b7cd1effd8d7f 0t0 TCP *:2121 (LISTEN)
ftpd 35258 jhqdoe 5u IPv6 0x817b7cd1effa3107 0t0 TCP *:2121 (LISTEN)
$
Whether this works or not I dunno; do you really need FTP?
To undo this change, sudo mv /etc/services.oops /etc/services

I am trying to deploy a WordPress website from a test server to a production server. wget seems to be an efficient solution for transferring lots of files between 2 servers via FTP.
I connect to the target server, go to the /var/www folder, and I type :
wget -r ftp://fred:[email protected]/mywebsite/
I runs 2 minutes and then states that 2312 files have been transferred. Well, but Filezilla would find over 5000 files !
At first, I notice that the .htaccess file was ignored.
How does it come not all files have been handled by wget?
How can I specify that I need all the files to be transferred?
|
The default recursion depth limit in wget is 5. This is primarily meant for the web where a large recursion is often a mistake, but the default also applies to FTP. Large recursion could also be a problem with FTP if the server has upward-pointing symbolic links.
To make a complete mirror, pass -l -1 to make the recursion unlimited, or better, pass the --mirror option.

The resolution to this problem was so, so not obvious. When I knew the proper search terms, obvious now, but not for the past couple of days, and understanding things better, the pieces started coming into place. Many posts on "VSFTPD directory content not listed" talked endlessly on passive vs. active, ports, permissions, use of hide_file, local_root, and others.
The real epiphany that I had came, when I asked myself there must be a way to get detailed logging or "vsftpd verbose logging" was my key term. That one thought and its implementation hit the mother load, so to speak. I got to know the existence of SELinux. That partially caused my misery.
This article, Installation and configuration of VSFTPD in CentOS with FTPS support and SELinux, did much to solve my problem.
The instructions created a couple of files, mypol.*, which I deleted. That gave me access to smurfs.txt, but I still had a problem with sub1.
I resolved that issue by noticing (why did it take me so long?) that the owner for sub1 was root, not datamover. When I fixed ownership (okay, permissions), then I had access to that folder as well.
I just tried downloading both files and success.
I still cannot upload to /home/ftp-docs/ and must maintain root as the owner for that folder as well as 755 permissions. Any deviation causes FTP to stop working. I can, however, upload to sub1. So the solution (workaround?) is to simply upload to a sub-folder.
In order to get things to work, I had to do the following at the end, where /mnt/raid1 is the home directory for the FTP client in this particular case. (I used to use /home/ftp-docs/.)
# /sbin/restorecon -v /mnt/raid1
# setsebool -P ftpd_full_access 1

-I is followed by a comma separated list of the directories you want to include.
However, note that this will just include the full name listed in -I, I believe, not part of the name, it sounds like you may want to be including directories based on a partial pattern. If anyone knows how to do regex type excludes/includes with wget, I'd like to learn that, I've looked for that for years.

I would like a simple (ideally one-liner, without separate script file) command to connect to an ftp server via anonymous login using my email address as the password.
My attempt is based on the syntax as shown here of basically ftp username:password@hostname; however this does not work for me when the password itself, being an email address, has an @ sign..
I also tried to provide a netrc file as a heredoc, as so: ftp hostname -N <<< 'login anonymous password [email protected]' but this still prompts me for a password during the ftp login..

I succeeded in transferring all files from a folder via ftp from a remote server to a raspberry, but I would like to transfer only new ones. Below is the working script i have.
#!/bin/bash -vx
ftp -in IP_SERVER<<END_SCRIPT
quote USER rem_user
quote PASS rem_pass
bin
prompt:off
cd /path_to_server_files
lcd /path_to_local_files
mget *.mp3
bye
END_SCRIPT
I have a company that provides background music to other companies. My method was leaving a computer in each one playing 24/7 or with other specific cron jobs, depending on the client. And the raspberry is a great way to do that instead a computer. The method i have right know that is working is a cron job per folder. Each folder has a type of music. So i will be putting different music from time to time in the server and the cron job will transfer those files once a week. It is set to transfer every mp3 file in that folder to the RPi. The thing is, it will transfer all the files there including the ones that were already there. If i put there, for example, 150 music files, it will take a long time transferring those, not to mention if it is done with all the folders since the RPi ARM is not that powerful. The solution would be not overwriting the files already there, just the new ones. Then after some time another cron job will delete all the files that have more than * days old.
I searched but it seems ftp doesn't have an option like this yet. So I found the wget command which allows to transfer without overwriting but i couldn't make it transfer multiple files. I have been trying to convert the script above with the wget command without success. Can someone with experience in this matter help out? It could be a problem with http also. Thanks in advance.
I have tried with wget command:
* * * * * wget -r -l1 -N -A.mp3 'ftp://serverUser:Password@serverIP/path_to_server_files' /var/www/rd/musica/teste/ftp11.log 2>&1

SOLUTION - I got this script to work. thank you for all the support you gave, If i have enough time to be working on this i'll keep trying the other options and make them work as well.
#!/usr/bin/python
import os
from ftplib import FTP
local_path='/path_to_local_files/'
os.chdir(local_path)
ftp = FTP(host='server_name_or_IP',user='username', passwd='password')
ftp.cwd('/path_to_local_files/')
f_list = ftp.nlst()
for f in f_list:
if not f.endswith("mp3"):
continue
new_f_name = local_path + f
if os.path.exists(new_f_name):
continue
print("Copying remote file <{0}>to local file <{1}>".format(f,new_f_name))
ftp.retrbinary('RETR '+ f, open(new_f_name,'wb').write)

Usually, when I drag a link to the terminal, the link target is pasted in the terminal. However, when I just dragged a FTP link from Chromium to my Terminal (first result on Google for "ftp pdf", ftp://ftp.ipswitch.com/ipswitch/manuals/ftpserv.pdf), a file download was immediately initiated (I knew because a desktop notification appeared).
I tried to locate the downloaded file using find ~ -iname '*.pdf' (also in /tmp), but I didn't find any traces. When I tried to reproduce the problem by dragging the ftp-URL again, the download completed much faster than before, from which I infer that the file is still cached, somewhere.
So, my question are:
Why is the ftp resource being downloaded after I drag the link to my Terminal?
(instead of being pasted as text, like http-URLs)
Where can I find the downloaded file? (I want to delete it)
|
Why is the ftp resource being downloaded after I drag the link to my Terminal? (instead of being pasted as text, like http-URLs)
The resource is not being "downloaded", but queried for its path and type. When dropping a file or URL on Konsole, it will try to convert it to a URL or path. Try for instance dropping a file:///tmp/ URL from Firefox to Konsole, it will instead show up as /tmp/. Another reason why this status call is needed is to check whether it is a directory or not (so you can drop a directory and select Change Directory To.
For this status discovery, Konsole depends on various protocols to provide a KIO interface. Now usually you should get a menu with Copy Here, Move Here, Link Here and Paste Location options. However for some reason (presumably a race condition bug?), the menu is not always offered and a download is immediately started (relevant code is in TerminalDisplay::dropEvent).
This was observed in Konsole 15.08.0 (Qt 5) on Arch Linux by the way.
Where can I find the downloaded file? (I want to delete it)
There is a good chance that the file was not actually saved and so you do not need to delete it. If you think it is still somewhere, look in /proc/$pid/fd/ for file descriptors of your process (or invoke lsof). (Have you also tried /var/tmp/ besides /tmp and ~?)
In the next 15.xx version, a new option is available to disable this Drag 'n' Drop functionality and simply paste everything as text (bug 304290). You can find this by opening your Profile settings, tab Mouse, option Disable drag and drop menu for URLs and files.

It was a wonder for me to see why the file owner changes when I log in the remote machine with different usernames.
Please see: 1st I logged in a remote machine using username : peacenews.
I entered a directory (pwd outputs / as the directory)
When I run ls to see the files there, I get the below:
(I am only showing the last few lines of the output)
-rwx rwxrwx 1 peacenew 504 198311940 Oct 4 02:21 Rotary club ORC, Delhi .m2p

226-Options: -l
226 18 matches total
Then I logged out and reconnected as anonymous user. This time also I logged in the same directory (having the same filenames)
See the output of ls please (last few lines only):
-rwxrwxrwx 1 504 504 198311940 Oct 4 02:21 Rotary club ORC, Delhi .m2p

Have a note at the 3rd column and compare with the previous one. Group owner for the files are the same but file owner changes. How come? It's a wonder!!!
|
I have resolved the matter on my own. I did my research by doing ftp to my own server.
The thing is that the file owner isn't changing. The 1st output shows the username and the 2nd shows the user ID for the same user. So simple but for confirming this I had to experiment with my own server.

I'm using vsftpd. By default, when I create a user, they are jailed in their directory which is /home/user.
I have enabled chroot_local_user=YES.
On the other hand, I also wanted to create a shared directory for all the FTP users. so in a nutshell, they have their own directory and they have a shared group folder
/
+/home
+user1
+shared_folder
How can I give the users access to the shared directory over FTP?
|
Try to "mount --bind" the shared directory into the user's directory.
mount --bind /home/actual_share/ /home/someguy/shared/
I assume you'll need to add group write to the "actual_share".
Got the idea from this forum post.

Folks over at SO couldn't answer this, so I am posting over here.
I need to do an FTP over SSL to a FileZilla Server running on a Windows server from an AIX Unix clien. I have the Host name of the destination server, the user id and password, and an SSL certificate. I am not sure how to install that certificate in AIX. When I do an ftp command (using the below code) from Unix it does connect successfully to the Filezilla server and I am able to do get and or mget. But, I am not sure if that is happening over SSL since I haven't installed the SSL Certificate yet. Do I need to install the Certificate in the Unix box (AIX)? if yes, then how? (specific steps and commands) and how to utilize the installed SSL certificate to do FTP after the installation?

The standard AIX ftp client does not support SSL or TLS. I'd be very interested if you find a way to get this going without 3rd party tools.
You can grab lftp from several sources ... we have used that in production successfully for a few years now on AIX 5.3. I've used the rpm available here lftp rpm for AIX, as well as compiling from source lftp download, although the latter can take a bit of extra work for things like GNUtls.
Newer versions of AIX 6.1+ include a secure option for the FTP client to use TLS.

I recently installed a CentOS machine for a couple of game servers.
I followed some tutorials on the web for that.
But. I want to sftp to store data on the server but it is very slow, I read that ftp is much faster. So my question is:
Can I change my SFTP to a FTP server and if so, how.
|
First you have to analyze why SFTP is "slow".
Does the CPU-usage on the server or client raise to a very high level during transfer?
Are there any lost packets on the network layer?
Do your duplex settings on the network adapters match those of the network devices (switches, routers, whatever) match each other?
Apart from that FTP uses a very different protocol, with no encryption and that can be difficult to get through firewalls, while SFTP operates over SSH and generally Just Works.

I'm using mget in an ftp script and would like mget to skip getting files that already exist in my local directory. Is there such a way? If so, is there also a way for mget to proceed if the local and remote files are different?
EDIT: Both are excellent answers, I went with the 2nd because it provided an example which I modified to:
lftp $HOST -u $USER,$PASSWD -e 'mirror --verbose=3 --only-newer --include "my-extended-regex-expression-of-include-file-patterns" / transfer/'
|
There are many different ftp implementations. I don't know of any ftp program that has an mget command that checks local files before downloading.
There are many programs that can download files over FTP and that do have what you want.
lftp
lftp ftp.example.com <<EOF
mirror --only-missing --file=/path/to/*.ext .
EOF
Replace --only-missing by --only-newer to download only newer files.
wget
wget -nc 'ftp://ftp.example.com/path/to/*.ext'
Add the option -N to download only newer files.
Alternatively, and this is the best solution to do complex things, mount the remote filesystem and then use normal file manipulation tools. You can mount an FTP directory with CurlFtpFS.
mkdir mnt
curlftpfs ftp://ftp.example.com/ mnt
rsync -a --ignore-existing mnt/*.ext . # replace --ignore-existing by -u to download only newer files
fusermount -u mnt

Question
When I start SSH server, my Debian automatically start the SFTP server as well - why is it design in such way?
Environment:
Linux 5.10.0-14-amd64 Debian 5.10.113-1 (2022-04-29) x86_64 GNU/Linux
ssh.service - OpenBSD Secure Shell server
Background
Today I realized:
when I want to handle http requests, I start a web server - Apache(2), Node.js, etc.
when I want to handle SSH, I start an SSH server
when I want to handle SFTP... Debian already started SFTP server for me
So I researched, and according to this post 378313/default-sftp-server-in-debian-9-stretch, I found out SFTP is started as "part of (Open)SSH" which makes perfect sense but also feels strange for reasons such as separation of concerns.
Unlike Windows, I have never felt Debian doing something unexpected or extra on my behalf. But today I felt it - after all I said systemctl restart ssh, not systemctl restart ssh-and-also-ftp (the latter command is made-up).
As I am new to Unix/Linux and its philosophy, I would appreciate if there are any good explanations for this situation.
|
Although SFTP is not part of the extensible core SSH protocol, it is built-in to at least one of the the common SSH implementations (OpenSSH) and therefore can be considered to be a standard component.
You can disable the functionality on the server if it's not required by changing /etc/ssh/sshd_config so that you remove the Subsystem line corresponding to the sftp-server.
For example, this line defines an external sftp-server utility to handle the SFTP service:
Subsystem sftp-server
This line defines an internal implementation of the SFTP service:
Subsystem internal-sftp
Removing or commenting out the Subsystem line will disable the SFTP service entirely.
# Subsystem …
Remember that tools such as rsync (if it's installed) and versions of scp will still function, though, so disabling SFTP will not of itself prevent users from transferring files between client and server. (Older versions of scp will work independently of SFTP. Newer versions use SFTP but can be forced to use the older protocol with the -O flag.) There are also "trivial" solutions such as ssh remoteHost cat somefile > local_copy_of_somefile to consider.

I'm accessing my localhost ftp server by Iceweasel or by the terminal (with the command ftp) while listening on the ftp port with
sudo tcpdump -vv -A 'port 20'
or
sudo tcpdump -vv -A port ftp
but nothing is printed although the connection is well established.
What am I doing wrong?
|
You indicated you are connecting via localhost. You will probably need to specify the interface with -i lo (or lo0 on a Mac), so use:
sudo tcpdump -i lo -vv -A port ftp
or on a Mac:
sudo tcpdump -i lo0 -vv -A port ftp
The you should see the traffic. The reason:
-i Listen on interface. If unspecified, tcpdump searches the system interface list for the lowest numbered, configured up interface (excluding loopback), which may turn out to be, for example, "eth0".

Tried to install curlftpfs in debian 12 says that the package is missing.
While I understand that the package is still not active developed I use often curlftpfs inside some virtual machines transfer to transfer between various fs eg. windows/linux VMs that pass files through filezilla server and so on.
So to me would be still useful use it even in a non secure FTPS fashion of the protocol.
Is there a way to install that package o a replacing package like that without break my debian 12 installation?

curlftpfs ships a single, simple binary package; you can safely install the Debian 11 version in Debian 12. Assuming you’re using amd64:

An article at this URI https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/6/html/security_guide/sect-security_guide-firewalls-iptables_and_connection_tracking
RELATED — A packet that is requesting a new connection but is part of an existing connection. For example, FTP uses port 21 to establish a connection, but data is transferred on a different port (typically port 20).
states that netfilter connection tracking mechanism is able to tag the ftp's out-of-band data-connection traffic to be in RELATED state with the ftp's control-connection. I have the following questions.
1) Can it do a similar tracking operation when data-connection is setup with non-default ports ?
2) If yes, Does it go through the FTP messages to find out the data-connection tuple (dst_ip, dst_prt, src_ip, src_prt) ? I know that is way too impractical to implement. So how does netfliter really achieves this ?
|
Does it go through the FTP messages to find out the data-connection tuple (dst_ip, dst_prt, src_ip, src_prt) ? I know that is way too impractical to implement.
Yes, that is exactly what it does. Why do you think it's too impractical?
You can look at the code yourself here:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/net/netfilter/nf_conntrack_ftp.c
Edit: OK, after your later comments I think I now understand what you meant.
The kernel would only need to analyze the beginning of the first few data packets of every TCP connection to see if it looks like a FTP control connection or not, and only mark the actual FTP control connections for further analysis. Only the connections that look like FTP would be monitored for data-connection tuples.
But a few years ago, it turned out that such fully-automatic tracking could be abused for malicious purposes. So with modern kernels, you now need to explicitly set up iptables connection tracking helper rules for protocols that need them, and that means if you use a non-default destination port for the FTP connection, you'll need a custom rule for that. But now you can fully control which interfaces, ports and connection destinations/directions will get the tracking helpers and which will not.
The connection tracking helper rule for FTP in regular should look like this:
iptables -t raw -A PREROUTING -p tcp --dport 21 -j CT --helper ftp
If you have a firewall that only accepts connections to specific inbound ports, you might also need a rule like this in your INPUT and/or FORWARD chain to accept the inbound active FTP connections:
iptables -A FORWARD -m conntrack --ctstate RELATED -m helper --helper ftp -p tcp --dport 1024: -j ACCEPT
For data connections of control connections using a non-default port, you'll need a slightly modified rule, e.g. to accept data connections belonging to a control connection in port 2121:
iptables -A FORWARD -m conntrack --ctstate RELATED -m helper --helper ftp-2121 -p tcp --dport 1024: -j ACCEPT
By the way, there are several connection tracking helper modules available:
ftp for FTP protocol, obviously.
irc for the Internet Relay Chat protocol. Port numbers will vary.
netbios-ns which you should not need for anything any more, since the WannaCry worm proved the SMB 1.0 protocol (that was used with the old NetBIOS style Windows filesharing) has a fatal flaw. Standard port for this would be 137/UDP.
snmp for the Simple Network Management Protocol, standard port 161/UDP.
RAS and Q.931 for h.323 video-conferencing sub-protocols (the old Microsoft NetMeeting etc). Ports 1719/UDP and 1720/TCP respectively.
sip for the SIP internet telephony protocol. Standard port 5060, both TCP and UDP supported.
sane for the network protocol of the SANE scanner software, standard port 6566/TCP.
pptp for the RFC2637 Point-to-Point Tunneling Protocol, a form of VPN.
tftp if you need to pass TFTP connections across a NAT.
amanda for the network protocol of Amanda backup software.

|
A similar question on stackoverflow (which involved java instead of wget, but really the underlying problem is with the URL syntax which is hopefully language-independent) was resolved by adding another slash and URL-encoding it, like this:
wget -m ftp://user:[email protected]/%2Ffoo/bar/
It works for me even without encoding, just with an extra slash:
wget -m ftp://user:[email protected]//foo/bar/
The first slash is thrown away (serving only as a separator between host and path), and the second slash actually counts as part of the path.

Found the answer in this link. Here an extract of my '/etc/vsftpd.conf':
# This powerful option allows the override of any config option specified
# in the manual page, on a per-user basis. Usage is simple, and is best
# illustrated with an example. If you set user_config_dir to be /etc/vsftpd_user_conf
# and then log on as the user "chris", then vsftpd will apply the settings
# in the file /etc/vsftpd_user_conf/chris for the duration of the session.
# Default: (none)
user_config_dir=/etc/vsftpd/vsftpd-user-conf
Each time a new ftp virtual user need a personal ftp directory, under the dir '/etc/vsftpd/vsftpd-user-conf' I create a file named as the username where I define the personal ftp directory and the auth on it (RO or RW).
Example for user 'test' (file '/etc/vsftpd/vsftpd-user-conf/test'):
# vsftpd per-user basis config file (override of any config option specified
# in the vsftpd server config file)
#
# TEMPLATE
#
# User test - Description for user test
#
# Set local root
local_root=/srv/vsftpd/test
# Disable any form of FTP write command.
# Allowed values: YES/NO

I send a Windows file using FTP to a Unix system and got appended ^M wherever a new line was intended, and I just want to remove them.
One method which I can opt is to run dos2unix command.
Can anyone suggest another method like sed command to remove such patterns?
|
Windows line endings consist of the two-character sequence CR, LF. CR is the carriage return character, sometimes represented as \r, \015, ^M, etc. A Unix line ending is just the LF character.
A way to convert Windows line endings to Unix line endings using only standard utilities present on all Unix variants is to use the tr utility.
tr -d '\r' <thefile >thefile.new && mv thefile.new thefile
If the file already has Unix line endings, its content won't be changed.
If you have many files to transform in the current directory, you can use a loop. Assuming that you don't have any files whose name ends with .new:
for x in *; do
tr -d '\r' <"$x" >"$x.new" && mv "$x.new" "$x"
done
Under Linux (excluding some embedded Linux systems) or Cygwin, you can use sed. The -i option to edit a file in place is specific to these systems. The notation \r for a CR character is more widespread but not universal.
sed -i -e 's/\r//g' thefile

I am using: SCO_SV scosysv 3.2 5.0.7 i386, and I am trying to download ssh and install it. But the only way I can do it, is by using FTP.
I have tried the following:
# ftp
ftp> ftp2.sco.com
?Invalid command
ftp>
What am I supposed to do?
I have never used FTP before in any Linux machine. I have Googled it, and I looked at every entry on the first page, and that is all talking about downloading packages from FTP sites—no use.

A very simple use of the ftp client would be to specify the server's hostname on the command line: ftp hostname. Then use ftp commands ls and cd [directory] to navigate in the server's directory structure and use get [file] to fetch the desired file.
Notes:
FTP servers usually allow login for anyone, provided you use the anonymous username.
To connect to ftp2.sco.com specifically, you'll have to activate passive mode using -p option: ftp -p ftp2.sco.com.

I've tried following numerous tutorials found on the net. The setup always starts out simple like
sudo apt-get intstall vsftpd
and then goes into edditing the /etc/vsftp.conf file. This is where the tutorials fail me becasue most of them either leave the setup for the users home directory, or starts getting in the chroot setup which appears more complicated than I need. Some tutorials attempt to explain how to set the defualt path by simply saying "add local_root=/var/www in your config file" which I added to the end of the file. This causes the prompt to get stuck after entering the username.
The problem here is that I don't know if the config directives have specific ordering. And if there is, the tutorials don't go into where it needs to be placed. I just need a single signon that points to the my /var/www
Thanks!

This is actually quite simple - all you need to do is change the home directory definition of that user's entry within /etc/passwd.

An FTP server behind a port forwarder can’t serve in the passive mode unless the software used has a special design to pass FTP data connections through. Cases are:
The NAT software able to sniff for 227 Entering Passive Mode in FTP control connection, to do port forwarding accordingly and some mangling of FTP control data.
The FTP server sending passive mode with visible (NAT) IP address and the NAT forwarding given range of ports.
Thanks to @derobert for pointing out a flaw in my original reasoning.
Linux kernel NAT is supplied with an (optional) FTP support. But if Linux is the guest, then its NAT has nothing to with the problem. The host system’s NAT must do NAT for the guest, indeed. Has the Windows’ NAT software in question such capability? Dunno, and it’s not a Linux question anyway. Recommended solution: replace NAT with bridging for the virtual machine.

I've managed to run vsftpd with unencrypted FTP, Implicit SSL, and Explicit SSL. What I'm looking for is a way to run it with Explicit SSL, but have a separate port for SSL.
For example: port 15000 for unencrypted, and port 15001 for SSL.
This is because I want to enable LAN users to connect unencrypted but WAN users to connect only encrypted.
I would use SSL on LAN too, but I'll be going Gigabit soon (laggard) and having a couple of users transfer files at speeds 70-100MB/sec is going to bring my server's CPU to its knees.
What has worked so far is to run two instances of vsftpd with different configs. I was hoping for a more tidy solution.
|
The answers to this question at Server Fault suggest the only way to do this is to run two separate instances of vsftpd, each with one of the configurations you want.

Right now we have a script that uses the FTP mget command to download all the files in a specific location. After after verifying the files have successfully downloaded we run a ftp delete command to delete each file that was downloaded. We noticed that each ftp delete is creating a new connection and I was wondering if it is possible to delete each file in one connection? I have a .txt file with all the file names that need to be deleted, but the file type varies a great deal so it would be nice to be able to target each file individually.
|
You might use lftp instead of the regular ftp client. With lftp you can use mget -E /path/to/files which will delete the source files after succesful transfer.
See http://lftp.yar.ru/lftp-man.html for the manual.

I'm using GNU's Inetutils FTP and have gotten it all set up except it does not automatically start when I turn on my system. In order to get it to work I have to start the standalone using "ftpd -D". I've figured out that I have xinetd running and I believe I need to use that to automatically start the daemon.
In the /etc/xinetd.d/ directory I've added a file named 'ftp'. Inside its contents are:
service ftpd
{
socket_type = stream
protocol = tcp
wait = no
user = root
server = /usr/bin/ftpd
instances = 20
}
*Doing a whereis shows that ftpd resides in /usr/bin/ftpd*
After adding it I reloaded the configuration and restarted the server.
/etc/init.d/xinetd reload
/etc/init.d/xinetd restart
My xinetd.conf file is as followed:
# Simple configuration file for xinetd
#
# Some defaults, and include /etc/xinetd.d/
defaults
{
instances = 60
log_type = SYSLOG authpriv
log_on_success = HOST PID
log_on_failure = HOST
cps = 25 30
}
includedir /etc/xinetd.d
There was also an inetd.config file in my system so I added the following for good measure though it doesn't seem inetd is running.
ftp stream tcp nowait root /usr/bin/ftpd in.ftpd -l -a
When I try to connected to my ftp server I get the error "ECONNREFUSED - Connection refused by server". Does anyone have any idea why this isn't getting started automatically by xinetd?
I got my information from this website:
http://www.cyberciti.biz/faq/linux-how-do-i-configure-xinetd-service/
|
I figured it out. Incase anyone else has this problem in the future, I forgot to specify a port to use for the service, changed the service name to ftp and set disable to no. Here is my final service file:
service ftp
{
port = 21
disable = no
socket_type = stream
protocol = tcp
wait = no
user = root
server = /usr/bin/ftpd
instances = 20
}
To get the logging working I used the following command:
/usr/sbin/xinetd -filelog /var/log/xinetd -f /etc/xinetd.conf

I had vsftpd set up such that I was able to upload files to a VPS I set up. The only problem is that I could not create directories. I set up vsftpd to disallow anonymous users, but allow virtual users to connect with their local credentials. At this point, the error message when I tried to create a folder changed from '550: Create directory failed' (I'm paraphrasing) to '550: Permission denied'. root owns the /var/www folder, and user with which I was authenticating had read and execute permissions but not write, so it makes sense that I wouldn't be able to create folders or files.
At this point I tried using chown and chmod to recursively change the group ownership to a group that my user was in and give my user write permission. This seemed to work at first - in the SSH session, I was able to cd to /var/www and create a new directory. However, when I tried to log in with my ftp client, I was now denied access.
What's even weirder is when I checked /var/log/vsftpd.log, I see the following lines:
Mon Jan 5 00:03:25 2015 [pid 801] CONNECT: Client "73.53.82.111"
Mon Jan 5 00:03:25 2015 [pid 800] [gradinafrica] OK LOGIN: Client "73.53.82.111"
...even though the login doesn't seem to work. What's going on?
EDIT (more info):
OS: Ubuntu 14.04
Architecture: Virtual private server (?)
When I set up the server, I disallowed logging in as root (as recommended by multiple sources) and set up a different user - 'gradinafrica' - which I added to the sudo group. I'm attempting to use this account for ftp. I haven't worked with sftp at all.

I would like to make shortcuts for gvfs mounts (I prefer to mount from the shell). For this, it is quite necessary/convenient not to have to enter the password for the ftp:// and sftp:// connections . Currently the only way I know is:
echo 12345 | gvfs-mount sftp://[email protected]/
Even though I can make the file's rights 700 (or even 100), I'm not sure if it's reasonably safe. Is it worse than .netrc items? I know about ssh-copy-id, but I can't access shell on most of my sftp servers.
Is there a better (standard) alternative to my approach? What do nautilus/caja do when they store the passwords?
|
You could use something like expect to provide the credentials each time you want to connect. It's not super secure but gives you what you want.
#!/usr/local/bin/expect --
set timeout -1
spawn gvfs-mount {args}
expect "User"
send "joe\n"
expect "Password:"
send "xxxxx\n"

Every 5 minutes some new files are downloaded via lftp to a local directory. I need to upload to another ftp only the non existing files. My script so far is:
#! /bin/bash
today=$(date +%Y%m%d)
today_files="rec."$today"_"
programa_dir="/home/user/local-dir"
# Download files, that do not exist in the local directory
lftp <<EOF
open -u user,pass ftp1
mget "$today_files*" -O $programa_dir
bye
EOF
# Upload the files
lftp <<EOF
open -u user,pass ftp2
lcd $programa_dir
mirror -R
bye
EOF
The mirror -R command doesn't recognize that only few files do not exist on the remote directory of the second ftp.
Is there a way to fix that? I need only to check the filename's , not the creation or the modification time of the files.
For the second ftp I tried
lftp <<EOF
open -u user,pass ftp2
mput $programa_dir/* -O /
bye
EOF
The result was the same - lftp upload all the files, no only the non existing.
|
I don't have access to LFTP at the moment, but I suspect you're looking for the --only-missing param, which is only usable with mirror.
Try this:

Anonymous / FTP users are allowed to access the FTP. Suppose if there is a user named as JOE then how can I allow him to access the FTP?
|
Not sure why you chose vsftpd, as the documentation is notoriously lacking/distributed. However, to answer your question - the simplest method of allowing registered user access is through enabling local users:
# Uncomment this to allow local users to log in.
local_enable=YES
There are other options, dependent on your needs, such as storing users in a database engine like MySQL. For more pertinent information, please check the following pages:
vsftpd configuration - online man page
viki (vsftpd community wiki) - local user configuration
viki (vsftpd community wiki) - virtual user configuration (db)
Assuming you meant you compiled vsftpd when you said "I made my own", then this information should apply. Let us know if this is an incorrect assumption or if the info provided doesn't assist.

I have installed ftp and sftp on my linux mint system, for wordpress file transfer
I had to create new user account for ftp and sftp on my system during the installation process.
Is it possible to run ftp and sftp from home user account, if yes, how to configure it.
And if single user account access is possible- what is advisable to have - multiple/seperate user accounts for ftp/sftp OR a single account merged with home user should be used
Tried searching for solutions on various forums, but did not get any clarity
Adding for more clarity:
For wordpress, i referred this link wordpress installation
To upload wordpress files to github, i required to convert it to static site, so for using 'simply static' wordpress plugin, i required ftp to upload files from my local wordpress installation.
Below are the links i used for ftp and sftp installation-
I used these 2 links for ftp installation
ftp install link 1 & its user creation snap
ftp install link 2 & its user creation snap
and for sftp
sftp install link & its user creation snap
in both ftp and sftp , had to create new users for using them on filezilla/ftp client
So i want to clarify , if I can use my default system user for ftp/sftp access and how to configure it. And what is advisable to create new seperate users and the reason for it.
I searched how and why for cant I use the system user for all these server process, but did not get any clarity from internet

The SFTP article you quoted is misleading at best, and inaccurate for the remainder. SFTP has nothing to do with vsftpd.
You can use sftp with your own user account already: sftp you@yourhost
If you have SFTP you almost certainly do not need to install vsftpd. At least, not unless you have a legacy file transfer application you need to support.
In direct response,
Is it possible to run ftp and sftp from home user account, if yes, how to configure it
Yes. Undo everything in the SFTP document, including the creation of a user account. It was already installed and configured for that.

Apologies if this isn't the right forum but I need the advice of an FTP familiar engineer. For security reasons, FTP services are being shut down on our company's Solaris 5 server. The reason is that man in the middle attacks are easier under the old FTP protocol. We run perl scripts that FTP OUT to other services, pull information in which we then sanitize and parse. What we don't want to do is function as an FTP host because we have no information that is relevant to put out. The software is old, there is no dev/test environment and wholesale "shutting down FTP services" ( where we can't even FTP out ) would break our production environment.
I'd prefer to keep running FTP out to other servers in the interim until we can convert all the scripts to SFTP but is this even possible? To be a client but not a host? I know this question is vague for this SE forum normal so feel free to close.
|
FTP service inbound is managed by an FTP server. FTP connections outbound are performed by a client. The two parts are independent of each other.
I'm not running Solaris so I can't give you the specifics process names, but this Oracle documentation link explains how to enable and disable the FTP server:
svcadm disable network/ftp # Stop and disable the FTP server
You can verify that the service is no longer running by attempting to connect to it with the FTP client (and you can also confirm that you can still make connections outbound):

find -type f -exec chmod 644 {} \;
and then:

This solved the problem and I was able to upgrade!

The permission to create a particular directory is not tied to the user account as tightly as you seem to think it is. That is, it's not part of the account's entry in /etc/passwd.
A user can create (or delete) a directory in another directory if that other directory is writable by the user or by a group that the user belongs to. This would also permit the user to create/delete files in that directory.
Example:
$ ls -ld .
drwxr-xr-x 2 myself staff 512 May 4 16:29 .
Here, only the user myself can create and delete files and directories while everyone is able to access the directory and list the directory content (the x and r permissions).
$ ls -ld .
drwxrwxr-x 2 myself staff 512 May 4 16:29 .
In this case, the myself user as well as all users in the group staff can create and delete files and directories in the current directory.

I'm using proftpd on my server (ubuntu 16.04 x86_64).
Default proftpd use standart 21 port. I can connect from my home notebook to ftp with active mode without problem.
Now I stop proftpd, change port from 21 to 10021, start service again. And now I can not connect with active mode, only with passive mode.
What's changed?
Also I can not understand, why works active mode? I have internet access by router. I do not forwand any ports to my notebook at router. As I now, on connect, my notebook (ftp client) create connection from some port > 1023 to server port 21. My notebook send to server also second (data) port to server and server connect from own port 20 to me with this data port. But how second connection can established, if my ports are closed from wan?

Your firewall (router) has a connection tracking helper for FTP. When it sees an FTP control connection (which it recognizes by TCP destination port == 21), it watches the commands. When it sees your client send the PORT command, it rewrites it (to your external IP address, and maybe a different port) and keeps track of the expected connection from the FTP server. When that connection arrives, it's allowed through.
When you changed the port, none of that happened, because 10021 isn't recognized as an FTP control connection.
On Linux, at least, that feature is the nf_conntrack_ftp module, and you can set the ports option to include 10021 if desired.
PS: A similar thing can be done with a firewall in front of the server, though in reverse: it's done on passive-mode transfers, instead of active-mode.

I am looking to install ftp (client) on my RHEL server. I can't access the internet directly, so I need to d/l the package.
I have downloaded ftp-0.17-17.2.x86_64 from redhat, and it is telling me:
libreadline.so.4()(64bit) is needed by ftp-0.17-17.2.x86_64
when I try and install readline-devel 4, it tells me a newer version is alreadyt installed; and readline 4 tells me it can't install because of conflicts with readline-devel.
find / -name libreadline* -print
/lib64/libreadline.so.6.0
/lib64/libreadline.so.6
/usr/lib64/libreadline.so
Can anyone help me to know what the next step is?

Try to download a more recent version of ftp, for instance ftp-0.17-54.el6.x86_64.rpm
See link http://mirror.centos.org/centos/6/os/x86_64/Packages/ or http://mirror.centos.org/centos/6/os/x86_64/Packages/ftp-0.17-54.el6.x86_64.rpm directly.
From the ldd output you can see that it is linked to libreadline.so.6:
ldd /usr/bin/ftp
linux-vdso.so.1 => (0x00007fffa67be000)
libreadline.so.6 => /lib64/libreadline.so.6 (0x00007fe48362c000)
libncurses.so.5 => /lib64/libncurses.so.5 (0x00007fe48340a000)
libc.so.6 => /lib64/libc.so.6 (0x00007fe483075000)
libtinfo.so.5 => /lib64/libtinfo.so.5 (0x00007fe482e54000)
libdl.so.2 => /lib64/libdl.so.2 (0x00007fe482c50000)
/lib64/ld-linux-x86-64.so.2 (0x00007fe48388b000)

I'm trying to compile php 5.2.x in debian gnu/linux:
./configure --with-ldap --enable-ftp --with-apxs2 --with-mcrypt

make
works perfect, but i need curl:
./configure --with-ldap --enable-ftp --with-apxs2 --with-mcrypt

make

UPDATE: the error is about FTP with openssl support:
./configure --with-openssl --enable-ftp
make

The problem was openssl, well, I installed openssl 0.9.8 from source:
Move to /usr/src compile it, and install it without man pages due to an error:
./config --prefix=/usr/local/openssl --openssldir=/usr/local/openssl
no-asm -fPIC
make
make install_sw
Then i compile php with this options:
./configure --with-openssl=/usr/local/openssl
--with-openssl-dir=/usr/local/openssl --with-curl --enable-ftp --with-ldap --with-apxs2 --enable-bcmath --with-bz2 --enable-calendar --enable-exif --enable-mbstring --with-mhash --enable-shmop --enable-soap --enable-sockets --enable-sysvmsg --enable-zip --with-zlib
make
UPDATE: works for 5.6.28 too
