Maybe 'KeepAlive yes' in your ~/.ssh/config. However, if you have a shell
that disconnects you during inactivity or some firewall/NAT freeing up
inactive ports, that could be a problem. One broadband gateway in
particular that closes inactive ssh sessions is Dlink DI-604 (although, it
was never a problem for my DI-704).

I sometimes forget to disconnect from my Solaris ISP overnight, and it
still works in the morning, unless my dynamic adsl has reconnected with a
different IP.
