TCP Timeout

[jbanker]

I am using a 2851 Router at one of my branch offices and I am getting a disconnection notice on a TCP session after 1 hour. I have disabled all security features for testing purposes and I am still getting disconnected. Any ideas on what default value I need to change or what may be causing this?

what are the endpoints involved in the tcp session? is the router one of the endpoints or is it just part of the transmission media for the tcp session?

see if you can use a sniffer from http://ethereal.com to monitor the tcp session and see how/why/who is initiating the tcp disconnect. (hopefully with a tcp FIN; this would narrow your search down a bit; even if not a FIN, the sniffer should provide you an excellent view of the entire session)

The router is one of the endpoints. I will try using ethereal on the host that is getting its session dropped. Thanks for the help, J-
