pyrad is an implementation of a RADIUS client as described in RFC2865. It takes care of all the details like building RADIUS packets, sending them and decoding responses.

Here is an example of doing a authentication request:

import pyrad.packet
from pyrad.client import Client
from pyrad.dictionary import Dictionary

srv=Client(server="radius.my.domain", secret="s3cr3t",
  dict=Dictionary("dicts/dictionary", "dictionary.acc"))

req=srv.CreateAuthPacket(code=pyrad.packet.AccessRequest,
      User_Name="wichert", NAS_Identifier="localhost")
req["User-Password"]=req.PwCrypt("password")

reply=srv.SendPacket(req)
if reply.code==pyrad.packet.AccessAccept:
    print "access accepted"
else:
    print "access denied"

print "Attributes returned by server:"
for i in reply.keys():
    print "%s: %s" % (i, reply[i])

pyrad requires Python 2.6 or later, or Python 3.2 or later

Installing is simple; pyrad uses the standard distutils system for installing Python modules:

python setup.py install
