  Moreover, "Python's" socket library is really just a thin wrapper around the platform socket library.  Restrictions such as "Raw sockets can only be created by root" are imposed by the platform, not by Python.  Similarly, if the platform socket library does not support raw sockets, Python will not support raw sockets.

  Since you seem to have the SOCK_RAW name in the socket module, I'm guessing that Itamar's guess of privileges being the problem is correct, rather than support being completely missing.
