Description torbin 1999-08-11 15:16:56 EDT
Recently upgraded a server from Redhat 5.2 to Redhat 6.0. The server is in front of the local firewall machine and when telnetting from behind the firewall will be disconnected from the server after a maximum of 30 minutes of being idle. If accessed from an outside source telnet is not disconnected even after hours of being idle, also a Redhat 5.2 machine that has not been upgraded does not disconnect the telnet sessions from behind the firewall.

are you using tcsh or bash as your shell?
Comment 2 torbin 1999-09-05 02:38:59 EDT
we use bash as the default shell

This is almost certainly a problem in your firewall. For example, Linux Firewalls disconnect idle TCP connections after certain period of time unless keepalive messages are sent. If the firewall in question is Linux, you might want to check out 'ipchains -M'. Also, you could try to downgrade your 6.0 -system's telnet RPM to one from 5.2, to see if you can isolate the problem.
