# OpenSSH/Overview

become the most widely used implementation of the SSH protocol. During
the first ten years of its existence, ssh has largely replaced older

Encryption has been a hot topic in computing for a long time. It became

# OpenSSH/SSH Protocols
OpenSSH uses the SSH protocol which connects over TCP. Normally, one SSH
session per TCP connection is made, but multiple sessions can be
multiplexed over a single TCP connection if planned that way. The
current set of Secure Shell protocols is SSH2. It is a rewrite of the
old, deprecated SSH1 ... |
# OpenSSH/Other SSH Implementations
## Dropbear

POSIX platforms. Dropbear is partially a derivative of OpenSSH and it is
often used in embedded systems because very small binaries can be
produced. Functions that are not neede... |
# OpenSSH/Client Applications
On the client side, ssh(1),
scp(1), and
sftp(1) provide a wide range of
capabilities. Interactive logins and file transfers are just the tip of
the iceberg.

client program.
: sftp(1) - FTP-like program that
works using the SSH protocol.

# OpenSSH/Client Configuration Files
Client configuration files can be per user or system wide, with the
former taking precedence over the latter and run-time arguments in the
shell overriding both. In these configuration files, one parameter per
line is allowed. The syntax is the parameter name followed by its value

# OpenSSH/Server
The OpenSSH Server, sshd(8), listens
for connections from clients and starts a new process or two for each
new incoming connection to handle key exchange, encryption,
authentication, program execution, and data exchange. In the case of
multiplexing, some processes are reused. It can run standalone and... |
# OpenSSH/Pattern Matching in OpenSSH Configuration
A pattern consists of zero or more non-whitespace characters. An
asterisk (**\***) matches zero or more characters in a row, and a
question mark (**?**) matches exactly one character. For example, to

: ssh-agent(1) - An
authentication agent that can store private keys.
: ssh-add(1) - A tool which adds
or removes keys to or from the above agent.

# Non-Programmer's Tutorial for Python 3/Boolean Expressions
Here is a little example of boolean expressions (you don\'t have to type
it in):
``` python
a = 6
b = 7
c = 42
print(1, a == 6)
print(2, a == 7)
print(3, a == 6 and b == 7)
print(4, a == 7 and b == 7)

# Non-Programmer's Tutorial for Python 3/Recursion
## Recursion
In Python, a recursive function is a function which calls itself.
### Introduction to recursion
So far, in Python, we have seen functions which call other functions.
However, it is possible for a function to call itself. Let\'s look at a
