making ssh connections persistent

[Kamaraju S Kusumanchi <raju.mailinglists@gmail.com>]

I often use ssh to access other computers at school. However, I can't make
these connections persistent. If there is no activity (say in 20 minutes),
the ssh connection just freezes up. As a result, I have to kill all the
gvim, xterm windows opened from that terminal. This is very annoying if I
am coding something.

Is it possible to make ssh connections which do not freeze even if there is
no activity for a while?

thanks
