ssh/sshd question

[Richard L. Hamilton]

While there are a couple of server (/etc/sshd_config) parameters for keepalives, I doubt they would force an idle timeout (notwithstanding a lot of people claiming that they will).  There is a client (/etc/ssh_config) side parameter ConnectTimeout, but I think that's to keep from having to wait a full two minutes on a connection to an unresponsive host, not an inactivity timeout.

In bash or I think ksh, the TMOUT environment variable can cause the shell to exit after the specified number of seconds of inactivity.
