Keep ssh sessions from timing out
The Ubuntu Blog has a nice lil' article about keeping SSH sessions alive.
It basically boils down to editing your /etc/ssh/ssh_config file and adding the following:
/etc/ssh/ssh_config
ServerAliveInterval 5
The number is the number of seconds to send the small keep alive which keeps the connection open. Ubuntu Blog suggests changing it from 5 to 240 or 300 (4 or 5 minutes).
