So we are experiencing some issues that we cannot figure out. Numerous students are calling stating they are getting kicked off after 5 minutes of use and cannot get back on until they reboot. What we have learned so far is the following.
1. Computer has a valid IP 2. Continuous ping works 3. Successful login to CCA 4. After approx 5 minutes pinging replies stop 5. Agent shows NO disconnect or logout message, but login option is grayed out 6. IP still valid 7. Unable to ping, browse web or login to CCA 8. Release/renew, or reboot, seems to enables network traffic again We are running 4.1.3 on the servers and 4.1.3.1 on the Agent. So far it is limited to Windows (all flavors). We have not received calls from Mac users yet. This sounds like the ARP issue experienced at the beginning of the semester. We are running In-band Real-IP Gateway. We have 2 pairs of HA servers and are looking into whether it is 1 server pair or both. We turned off our heartbeat timers and also increased them to a much higher value than 5 minutes in case this was the issue, and neither solved it. We also disabled any certified device timers we had and that didn't help. The default lease time is 7200 seconds so that doesn't appear to be the issue either. If anyone can suggest anything for us to look at we are open to any suggestions. Thanks in advance. Brian Beausoleil Network Administrator Southern CT State University
