Dear List, I hope you are all doing fine. I know that the following question might be 'out of scope' of the user's list but still, I would like to ask some user's experience. I successfully implemented '802.1x or MAC-Auth' as described on the how-to: the 802.1x is PEAP based (server's certificate deployed on all client) with Computer authentication (instead of user authentication) + Mac verification (in a specific table in radius db), and for all non-capable 802.1x end-points (such as pointers) just a mac verification. However, I m still confused about the following issues: - since the above are just only deployed in my testing environment, and I m supposed to deploy the same for 1k users, how much memory (RAM,HD,Processor) should I allocate to radius server! The DB is also on the same server as Freeradius. - what kind of extra-layer could I add to the authentication layer (PC authentication PEAP + MSCHAP v2, against AD 2008, + MAC Verification) to make it even 'more secure'? Thank you, Regards, KEN
