[PLUG] ssh connection hangs after idling

[Vincent Yau]

Hi:

I notice this behavior on my Ubuntu box.  If I ssh into it, steps away for a
while and comes back, the ssh session
would hang.  I added

    ServerAliveInterval 155

to /etc/ssh/ssh_config but it does not see to solve the problem.

Is there another ssh config I can put in so my ssh connections won't hang
after idling for a period of time?

Thanks
