pyrad is an implementation of a RADIUS client and server as described in RFC2865, 2866, and others. It takes care of all the details like building RADIUS packets, sending and receiving them, and en-/decoding responses. (RADIUS is a common protocol used for authentication, authorisation and accounting for remote access (and similar) services).

Changes since previous release ------------------------------

* Fix time-handling in the client packet sending code: it would loop forever since the now time was updated at the wrong moment. Fix from Michael Mitchell. * Fix passing of dict parameter when creating reply packets

Example -------

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])

And an example for a trivial RADIUS server:

from pyrad import dictionary, packet, server

class FakeServer(server.Server): def _HandleAuthPacket(self, fd, pkt): server.Server._HandleAuthPacket(self, fd, pkt)

reply=self.CreateReplyPacket(pkt) reply.code=packet.AccessAccept self.SendReplyPacket(fd, reply)

srv=FakeServer(dict=dictionary.Dictionary("dictionary")) srv.hosts["127.0.0.1"]=server.RemoteHost("127.0.0.1", "s3cr3t", "localhost") srv.BindToAddress("") srv.Run()

Requirements ------------

pyrad requires Python 2.2 or later.
