Thanks for the fast reply.
See http://deployingradius.com It has a detailed guide for EAP / PEAP.
I'm actually following that one, it's very helpful, however I keep running into problems that aren't covered.
You're running it as a normal user, and the file is owned by root (or another user).
I'm sorry I should have included more information the first time round. root@hd:~# sudo freeradius -X FreeRADIUS Version 2.1.10, for host i686-pc-linux-gnu, built on Sep 24 2012 at 17:53:32 Copyright (C) 1999-2009 The FreeRADIUS server project and contributors.

I thought I was running it as root (root@hd), and I also used sudo just to be sure (not too confident on Ubuntu's root system). Let me know if that's not the case. Also another thing I forgot to mention is this time the basic radtest fails. root@hd:~# radtest testing password 127.0.0.1 0 testing123 Sending Access-Request of id 137 to 127.0.0.1 port 1812 User-Name = "testing" User-Password = "password" NAS-IP-Address = 127.0.1.1 NAS-Port = 0 Sending Access-Request of id 137 to 127.0.0.1 port 1812 User-Name = "testing" User-Password = "password" NAS-IP-Address = 127.0.1.1 NAS-Port = 0 Sending Access-Request of id 137 to 127.0.0.1 port 1812 User-Name = "testing" User-Password = "password" NAS-IP-Address = 127.0.1.1 NAS-Port = 0 radclient: no response from server for ID 137 socket 3 I had it working before but I have no idea why it won't work anymore, hopefully this is related and will help in some way.
