Good Day,

We have installed two Ubuntu Linux servers (One is a web server, the other a tftp server) both are running Ubuntu Server 11.10

We have been troubleshooting the issue of the servers not allowing traffic if there has not been any activity between 3 - 5 minutes. This causes users not to be able to access the web site or for the IT staff to use the tftp sever.

we are unable to SSH in so we will have to log into the servers locally and ping a host on the network, then traffic will start flowing again.

We have setup a cron job to ping an internal network address every 60 seconds on the web server which seems to be a work around until we can find a permanent solution for the issue. We have not done this on the tftp server due that we want to leave it as is so we can test possible solutions in it. It is only used for our switches and routers.

A solution to this issue will be greatly appreciated.

Thanks,
