Dear all, I would like my user to get a session time-out of 20 minutes. While looking at the debug, I noticed that my users matched the default entry [12] attrs.accounting.response and get authenticate every 10 minutes (in fact, this even take over the session time-out attribute that I could attribute to a specific user) So, basically, I don't know how to control it. DEFAULT Vendor-Specific =* ANY, Message-Authenticator =* ANY, Proxy-State =* ANY I thank that was the file that I could configure to get all my users re-authenticate after 20 minutes. Then, I had a look to the attrs file I noticed that the Idle-time out was of 10 minutes..So, I decided to put the Idle time of 1200 instead of the regular 600 who was written in this file. DEFAULT Service-Type == Framed-User, Service-Type == Login-User, Login-Service == Telnet, Login-Service == Rlogin, Login-Service == TCP-Clear, Login-TCP-Port <= 65536, Framed-IP-Address == 255.255.255.254, Framed-IP-Netmask == 255.255.255.255, Framed-Protocol == PPP, Framed-Protocol == SLIP, Framed-Compression == Van-Jacobson-TCP-IP, Framed-MTU >= 576, Framed-Filter-ID =* ANY, Reply-Message =* ANY, Proxy-State =* ANY, EAP-Message =* ANY, Message-Authenticator =* ANY, MS-MPPE-Recv-Key =* ANY, MS-MPPE-Send-Key =* ANY, MS-CHAP-MPPE-Keys =* ANY, State =* ANY, Session-Timeout <= 28800, Idle-Timeout <= 1200, Port-Limit <= 2 Unfortunately, that did not work and now, I am still stuck to figure out how could I do that. To sum up this issue, I got Alvarion NAS, from my users, I can see accounting start and accounting stop packet, every 10 minutes, I got an accounting packet stop from my users with everytime the same termination cause = lost-carrier. Thanks in advance for you help. Let me know if you need more details. Regards Sylvain
