Hi,
Presumably this involves PEAP/MSCHAPv2 I can't work out how to do it without using a Windows client and a wireless infrastructure we don't have yet. (or even if it is doable)
you dont need wireless to do such testing - there are plenty of ethernet switches out there that do 802.1x and can throw the EAP authentication to your RADIUS box... ...with this in mind, you could use wpa_supplicant on linux - yes it does wired 802.1x nicely... eg have this in the config eap=PEAP identity="domain\username" password="secret_password" ca_cert="/etc/cert/ca.pem" phase1="peaplabel=0" phase2="auth=MSCHAPV2" or..since you're playing with wpa_supplicant..use its handy tool eapol_test - very useful. of course, with wired 802.1x you can also play with the windows client and get used to its quirks and foibles. alan
