Raw packet socket for Linux

raw sockets made easy
=====================

Only in linux, sorry.


Rationale
---------

If you need raw sockets in your python script, you have to run it as root
or make it SUID root. Alternatively, you can use file capabilities to grant
extended priviliges to a binary. Unfortunately, this only works on binaries
and not on scripts, which means you have to set the capability on the
python binary.


How does it work?
-----------------

As mentioned above, you can only set capabilties on a binary. Therefore,
this module has a helper binary, which will get the RAW_NET capability.
This binary is spawned by the rawsocket python module every time you create
a new raw socket. The helper uses its capability to create the socket and
then passes the file descriptor back to the calling program.

In linux you can pass file descriptors through unix domain sockets by using
the ``sendmsg()`` system call and ``SCM_RIGHTS``. See also `fd passing`_.


Installation
------------

Use PIP::

  pip install rawsocket

Or use the standard method::

  python setup.py install

This will install the extension module and the helper binary. But it will
*not* set the file capability on the helper binary. You have two choices:

1. Grant every user access to the helper (simple, *not recommended*)::

     setcap cap_net_raw+ep rawsocket-helper

2. Grant access only to users which are member of a specific group
   (recommended)::

     chmod 750 rawsocket-helper
     chown root:yourgroup rawsocket-helper
     setcap cap_net_raw+ep rawsocket-helper


Example
-------

.. code:: python

  import socket, rawsocket
  fd = rawsocket.rawsocket_fd()
  s = socket.fromfd(fd, socket.AF_PACKET, socket.SOCK_RAW)

You see easy as pie ;)
