module: bigip_snmp_trap
short_description: Manipulate SNMP trap information on a BIG-IP.
description:
- Manipulate SNMP trap information on a BIG-IP.
version_added: 2.4
options:
name:
description:
- Name of the SNMP configuration endpoint.
required: True
snmp_version:
description:
- Specifies to which Simple Network Management Protocol (SNMP) version
the trap destination applies.
choices:
- 1
- 2c
community:
description:
- Specifies the community name for the trap destination.
destination:
description:
- Specifies the address for the trap destination. This can be either an
IP address or a hostname.
port:
description:
- Specifies the port for the trap destination.
network:
description:
- Specifies the name of the trap network. This option is not supported in
versions of BIG-IP < 12.1.0. If used on versions < 12.1.0, it will simply
be ignored.
choices:
- other
- management
- default
state:
description:
- When C(present), ensures that the cloud connector exists. When
C(absent), ensures that the cloud connector does not exist.
default: present
choices:
- present
- absent
notes:
- Requires the f5-sdk Python package on the host. This is as easy as pip
install f5-sdk.
- This module only supports version v1 and v2c of SNMP.
- The C(network) option is not supported on versions of BIG-IP < 12.1.0 because
the platform did not support that option until 12.1.0. If used on versions
< 12.1.0, it will simply be ignored.
extends_documentation_fragment: f5
requirements:
- f5-sdk >= 2.2.0

Django comes with a standard `model level` permission system. You can
check whether users are logged-in and have privileges to act on things
model wise (can a user add a project? can a user view projects?).
Django-guardian adds a `row level` permission system. Now not only can you
decide whether a user can add a project or view projects, you can specify exactly
which projects a user has or has not access to.
This brings up the reason the following function: tasks are part of a project,
and it would add a tremendous headache (and redundancy) to specify row level permissions
for each task. Instead, we check the row level permissions of the project
to which a task belongs to.
Perhaps this could be added as a django-rest filter?

- files
- validate
short_description: Replace all instances of a particular string in a
file using a back-referenced regular expression.
description:
- This module will replace all instances of a pattern within a file.
- It is up to the user to maintain idempotence by ensuring that the
same pattern would never match any replacements made.
version_added: "1.6"
options:
dest:
required: true
aliases: [ name, destfile ]
description:
- The file to modify.
regexp:
required: true
description:
- The regular expression to look for in the contents of the file.
Uses Python regular expressions; see
U(http://docs.python.org/2/library/re.html).
Uses multiline mode, which means C(^) and C($) match the beginning
and end respectively of I(each line) of the file.
replace:
required: false
description:
- The string to replace regexp matches. May contain backreferences
that will get expanded with the regexp capture groups if the regexp
matches. If not set, matches are removed entirely.
backup:
required: false
default: "no"
choices: [ "yes", "no" ]
description:
- Create a backup file including the timestamp information so you can
get the original file back if you somehow clobbered it incorrectly.
others:
description:
- All arguments accepted by the M(file) module also work here.
required: false
follow:
required: false
default: "no"
choices: [ "yes", "no" ]
version_added: "1.9"
description:
- 'This flag indicates that filesystem links, if they exist, should be followed.'

description:
- "Adds or removes SSH authorized keys for particular user accounts"
version_added: "0.5"
options:
user:
description:
- The username on the remote host whose authorized_keys file will be modified
required: true
key:
description:
- The SSH public key(s), as a string or (since 1.9) url (https://github.com/username.keys)
required: true
path:
description:
- Alternate path to the authorized_keys file
required: false
default: "(homedir)+/.ssh/authorized_keys"
version_added: "1.2"
manage_dir:
description:
- Whether this module should manage the directory of the authorized key file. If
set, the module will create the directory, as well as set the owner and permissions
of an existing directory. Be sure to
set C(manage_dir=no) if you are using an alternate directory for
authorized_keys, as set with C(path), since you could lock yourself out of
SSH access. See the example below.
required: false
choices: [ "yes", "no" ]
default: "yes"
version_added: "1.2"
state:
description:
- Whether the given key (with the given key_options) should or should not be in the file
required: false
choices: [ "present", "absent" ]
default: "present"
key_options:
description:
- A string of ssh key options to be prepended to the key in the authorized_keys file
required: false
default: null
version_added: "1.4"
exclusive:
description:
- Whether to remove all other non-specified keys from the authorized_keys file. Multiple keys
can be specified in a single C(key) string value by separating them by newlines.
- This option is not loop aware, so if you use C(with_) , it will be exclusive per iteration
of the loop, if you want multiple keys in the file you need to pass them all to C(key) in a
single batch as mentioned above.
required: false
choices: [ "yes", "no" ]
default: "no"
version_added: "1.9"
validate_certs:
description:
- This only applies if using a https url as the source of the keys. If set to C(no), the SSL certificates will not be validated.
- This should only set to C(no) used on personally controlled sites using self-signed certificates as it avoids verifying the source site.
- Prior to 2.1 the code worked as if this was set to C(yes).

This module customises the behaviour of the
OpenGL.raw.GL.MESA.resize_buffers to provide a more
Python-friendly API
Overview (from the spec)
Mesa is often used as a client library with no integration with
the computer's window system (an X server, for example). And since
Mesa does not have an event loop nor window system callbacks, it
cannot properly respond to window system events. In particular,
Mesa cannot automatically detect when a window has been resized.
Mesa's glViewport command queries the current window size and updates
its internal data structors accordingly. This normally works fine
since most applications call glViewport in responce to window size
changes.
In some situations, however, the application may not call glViewport
when a window size changes but would still like Mesa to adjust to
the new window size. This extension exports a new function to solve
this problem.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/MESA/resize_buffers.txt

class RequestValidator(object):
"""A validator/datastore interaction base class for OAuth 1 providers.
OAuth providers should inherit from RequestValidator and implement the
methods and properties outlined below. Further details are provided in the
documentation for each method and property.
Methods used to check the format of input parameters. Common tests include
length, character set, membership, range or pattern. These tests are
referred to as `whitelisting or blacklisting`_. Whitelisting is better
but blacklisting can be usefull to spot malicious activity.
The following have methods a default implementation:
- check_client_key
- check_request_token
- check_access_token
- check_nonce
- check_verifier
- check_realms
The methods above default to whitelist input parameters, checking that they
are alphanumerical and between a minimum and maximum length. Rather than
overloading the methods a few properties can be used to configure these
methods.
* @safe_characters -> (character set)
* @client_key_length -> (min, max)
* @request_token_length -> (min, max)
* @access_token_length -> (min, max)
* @nonce_length -> (min, max)
* @verifier_length -> (min, max)
* @realms -> [list, of, realms]
Methods used to validate/invalidate input parameters. These checks usually
hit either persistent or temporary storage such as databases or the
filesystem. See each methods documentation for detailed usage.
The following methods must be implemented:
- validate_client_key
- validate_request_token
- validate_access_token
- validate_timestamp_and_nonce
- validate_redirect_uri
- validate_requested_realms
- validate_realms
- validate_verifier
- invalidate_request_token
Methods used to retrieve sensitive information from storage.
The following methods must be implemented:
- get_client_secret
- get_request_token_secret
- get_access_token_secret
- get_rsa_key
- get_realms
- get_default_realms
- get_redirect_uri
Methods used to save credentials.
The following methods must be implemented:
- save_request_token
- save_verifier
- save_access_token
Methods used to verify input parameters. This methods are used during
authorizing request token by user (AuthorizationEndpoint), to check if
parameters are valid. During token authorization request is not signed,
thus 'validation' methods can not be used. The following methods must be
implemented:
- verify_realms
- verify_request_token
To prevent timing attacks it is necessary to not exit early even if the
client key or resource owner key is invalid. Instead dummy values should
be used during the remaining verification process. It is very important
that the dummy client and token are valid input parameters to the methods
get_client_secret, get_rsa_key and get_(access/request)_token_secret and
that the running time of those methods when given a dummy value remain
equivalent to the running time when given a valid client/resource owner.
The following properties must be implemented:
* @dummy_client
* @dummy_request_token
* @dummy_access_token
Example implementations have been provided, note that the database used is
a simple dictionary and serves only an illustrative purpose. Use whichever
database suits your project and how to access it is entirely up to you.
The methods are introduced in an order which should make understanding
their use more straightforward and as such it could be worth reading what
follows in chronological order.

straightforward for the provider to verify whether the supplied

specification but it is commonly used to restrict access to a subset
of protected resources such as "photos".
realms is a convenience parameter which can be used to provide
a per view method pre-defined list of allowed realms.
Can be as simple as::
from your_datastore import RequestToken
request_token = RequestToken.get(token, None)
if not request_token:
return False
return set(request_token.realms).issuperset(set(realms))
This method is used by
* ResourceEndpoint
"""
raise self._subclass_must_implement("validate_realms")
def validate_verifier(self, client_key, token, verifier, request):
"""Validates a verification code.
:param client_key: The client/consumer key.
:param token: A request token string.
:param verifier: The authorization verifier string.
:param request: OAuthlib request.
:type request: oauthlib.common.Request
:returns: True or False
OAuth providers issue a verification code to clients after the
resource owner authorizes access. This code is used by the client to
obtain token credentials and the provider must verify that the
verifier is valid and associated with the client as well as the
resource owner.
Verifier validation should be done in near constant time
(to avoid verifier enumeration). To achieve this we need a
constant time string comparison which is provided by OAuthLib
in ``oauthlib.common.safe_string_equals``::
from your_datastore import Verifier
correct_verifier = Verifier.get(client_key, request_token)
from oauthlib.common import safe_string_equals
return safe_string_equals(verifier, correct_verifier)

"""Verify that the given OAuth1 request token is valid.
:param token: A request token string.
:param request: OAuthlib request.
:type request: oauthlib.common.Request
:returns: True or False
This method is used only in AuthorizationEndpoint to check whether the
oauth_token given in the authorization URL is valid or not.
This request is not signed and thus similar ``validate_request_token``

:param token: An access token string.
:param realms: A list of realms the client attempts to access.
:param request: OAuthlib request.
:type request: oauthlib.common.Request
:returns: True or False
This prevents the list of authorized realms sent by the client during
the authorization step to be altered to include realms outside what
was bound with the request token.

return all((r in valid_realms for r in realms))

one primary secret (a master key or a pass phrase).
This is typically done to insulate the secondary keys from each other,
to avoid that leakage of a secondary key compromises the security of the
master key, or to thwart attacks on pass phrases (e.g. via rainbow tables).

An 8 byte string to use for better protection from dictionary attacks.
This value does not need to be kept secret, but it should be randomly
chosen for each derivation.

# Level Goal
#
# Your goal is to connect to port 5842 on vortex.labs.overthewire.org and read
# in 4 unsigned integers in host byte order. Add these integers together and
# send back the results to get a username and password for vortex1.
#
# This information can be used to log in using SSH.
#
# Note: vortex is on an 32bit x86 machine (meaning, a little endian architecture)
io = remote('vortex.labs.overthewire.org', 5842)
# You can receive data manually. We want exactly four bytes.
data = io.recvn(4)
# Now let's unpack them as a 32-bit little-endian integer
value = unpack(data, bits=32, endian='little')
# By default, pwntools sets everything to i386, which is 32-bit little endian.
# Because of this, there is no need to specify the extra arguments.
#
# The above line could instead just read:
value = unpack(data)
# There's also a helper available directly on the tube itself
# Let's read the other integers
value += io.unpack()
value += io.unpack()
value += io.unpack()
# Now let's send it back
io.pack(value)

version_added: "2.2"
short_description: Manages VXLAN Network Virtualization Endpoint (NVE).
description:
- Manages VXLAN Network Virtualization Endpoint (NVE) overlay interface
that terminates VXLAN tunnels.
author: Gabriele Gerbino (@GGabriele)
notes:
- Tested against NXOSv 7.3.(0)D1(1) on VIRL
- The module is used to manage NVE properties, not to create NVE
interfaces. Use M(nxos_interface) if you wish to do so.
- C(state=absent) removes the interface.
- Default, where supported, restores params default value.
options:
interface:
description:
- Interface name for the VXLAN Network Virtualization Endpoint.
required: true
description:
description:
- Description of the NVE interface.
host_reachability:
description:
- Specify mechanism for host reachability advertisement.
type: bool
shutdown:
description:
- Administratively shutdown the NVE interface.
type: bool
source_interface:

- Specify the loopback interface whose IP address should be
used for the NVE interface.
source_interface_hold_down_time:
description:
- Suppresses advertisement of the NVE loopback address until
the overlay has converged.
state:
description:
- Determines whether the config should be present or not
on the device.

'''SMTP/ESMTP client class.
This should follow RFC 821 (SMTP), RFC 1869 (ESMTP), RFC 2554 (SMTP
Authentication) and RFC 2487 (Secure SMTP over TLS).
Notes:
Please remember, when doing ESMTP, that the names of the SMTP service
extensions are NOT the same thing as the option keywords for the RCPT
and MAIL commands!
Example:
>>> import smtplib
>>> s=smtplib.SMTP("localhost")
>>> print(s.help())
This is Sendmail version 8.8.4
Topics:
HELO EHLO MAIL RCPT DATA
RSET NOOP QUIT HELP VRFY
EXPN VERB ETRN DSN
For more info use "HELP <topic>".
To report bugs in the implementation send email to
sendmail-bugs@sendmail.org.
For local information send email to Postmaster at your site.
End of HELP info
>>> s.putcmd("vrfy","someone@here")
>>> s.getreply()
(250, "Somebody OverHere <somebody@here.my.org>")

Create `image_2d` as a two-dimensional NumPy array by stacking a
sequence of 1-dimensional arrays (rows).

# array with data type ``numpy.uint16``. This is a feature of NumPy,
# discussed further in
# http://docs.scipy.org/doc/numpy/user/basics.types.html .
# You can use avoid the explicit conversion with
# ``numpy.vstack(pngdata)``, but then NumPy will pick the array's data
# type; in practice it seems to pick ``numpy.int32``, which is large enough
# to hold any pixel value for any PNG image but uses 4 bytes per value when
# 1 or 2 would be enough.

# (`pngdata` is often an iterator) it will attempt to create a size 1

If the data is three-dimensional, as it is above, the best thing
to do is reshape it into a two-dimensional array with a shape of
