Hi. On Cisco Aironet 350 you can set wep key rotation on, setting a time in the vlan setup (or in the general wep setup, if you don't use VLAN).
It should negotiate a new wep key.
I never tried because it seems Xsupplicant for Linux does not support dynamic key negotiation.
You have to configure autoMPPEkeys (or similar, I don't have the config files on sight) too.

Hi all

I'm using Radiator in WLAN to autenticate 802.1X PEAP clients (Windows XP) to radius flat user-file database. System works fine, but for extra security I would like to change WEP-keys if WLAN user is connected for long time. Does anybody know should it be possible to rekey WEP-keys with Radiator if a wlan-connection is on for example over 10 minutes ?

Idea is that WEP-key that is used to crypt traffic would be changed so often that it would not be practical to try to crack it. I remember reading from somewhere that this should be supported with LEAP, PEAP and TTLS ?
Wlan AP is Cisco Aironet 350 and client card are Cisco Aironet 350 Pcmcia cards and Nokia D211 cards.


Thanks for all replys in advance
