I still have the same problem as well (on Debian); mucked with the net.ipv4.tcp_* parameters, still no joy in keeping either the WiFi or hard Ethernet ports alive more than a few hours. This is not just SSH - the ports become unresponsive to ping as well. Given my application requires availability, this is a problem.
The connections *seemed* to say alive longer when I set up a process to ping the router every 5 minutes or so, but still died eventually. Does anyone have suggestions as to how we might monitor the ports to determine the cause of death? I've been netstat'ing, logging and ps'ing every way I could imagine, with no clue as to what is causing the problem. Guess I could set up a cron job to kill the board every few hours, but that seems inelegant ;-) On Sunday, March 16, 2014 2:05:04 PM UTC-6, Chris Shiplet wrote: > > Unfortunately I was never able to resolve this, although I didn't try > rebuilding the kernel or anything.
