Re: [WIRELESS-LAN] Macintosh- Ongoing Connectivity Issues
Hi We have a mixed network with a mixture of Cisco fat AP's and Aruba thin AP's and we have found that some Apple Macs are having problems connecting to the Aruba setup. It seems that the authentication periodically fails and I see error messages like these from RADIUS :- Auth fail logs from FreeRADIUS :- Thu Jan 22 16:59:44 2009 : Error: TLS Alert write:fatal:bad record mac Thu Jan 22 16:59:44 2009 : Error: rlm_eap: SSL error error:1408F119:SSL routines:SSL3_GET_RECORD:decryption failed or bad record mac Thu Jan 22 16:59:44 2009 : Error: SSL: SSL_read failed in a system call (-1), TLS session fails. Auth fail reason from IAS :- Reason-Code = 260 Reason = The message or signature supplied for verification has been altered Has anyone else seen anything similar to this?

Re: [WIRELESS-LAN] 802.1x- Who's doing it and how far along

Why? Yes, we do 802.1x with PEAP or TTLS. RADIUS server is FreeRADIUS and AP's are Cisco or Foundry. We also participate in eduroam.

Re: [WIRELESS-LAN] Multiple VLANs configuration

However after disconnecting from the network and trying to get back on, Windows XP does not ask for the user credentials and uses a cached entry to connect again. Where would you set the host to ask for credentials every time a connection is initiated? Hi If your RADIUS server supports it could you configure EAP-TTLS and install the SecureW2 client on your XP boxes? http://www.securew2.com/uk/index.htm The SecureW2 client is more configurable and I think you can tell it to ask you for the password every time as one or the options.

It is expensive but it does the job - reliably. We use it for all aspects of our wireless network - from surveys to wireless troubleshooting and packet captures. Almost everything you could possibly get for troubleshooting a wired network.

We are looking into some type of very sensitive wireless analyzer equipment that will be used to go out to the dorms, walk the halls, and pinpoint the rooms the ad-hoc, etc. signals are coming from. Anyone have suggestions on tools you are successfully using for this purpose? Hi I use a YellowJacket B/G from Berkeley Varitronics Systems :- http://www.bvsystems.com/Products/WLAN/YJ802.11bg/YJ802.11bg.htm This device is really useful for locating rogue devices as it has an optional directional antenna and a signal strength meter with a constant beeping sound which gets more high pitched the closer you get to the source. It can also track down movement detectors and video senders and anything else you can think of using the spectrum analyser display.
