Hi all, Not directly related to FreeRADIUS but I gather people here have some experience with Cisco WiSMs and 802.1x. I'm trying to use radclient to craft a Disconnect-Request packet to disconnect a user on an 802.1x network. I've checked the RFCs for the Disconnect-Request packets and I believe I am providing all the necessary attributes to disconnect a user, however the WiSM always responds: rad_recv: Disconnect-NAK packet from host 172.17.107.211 port 3799, id=219, length=26 Error-Cause = Missing-Attribute I am sending packets like these: Sending Disconnect-Request of id 219 to 172.17.107.211 port 3799 User-Name = "jg4461" Calling-Station-Id = "00:1b:63:08:b4:eb" Framed-IP-Address = 172.21.107.197 Called-Station-Id = "00:21:55:ac:5b:60:ResNet-Wireless" NAS-Port-Id = "29" NAS-Port-Type = Async Acct-Session-Id = "jg44614ddcd9e6/00:1b:63:08:b4:eb/222935" NAS-IP-Address = 172.17.107.211 NAS-Port = 29 NAS-Identifier = "wism11" So, does anyone know which attributes I must send to disconnect a user in this way? Is there an easier way of doing it? Many thanks, Jonathan
