Many consumer routers/DSL modems do not handle long running SSH
connections well. They sometimes tend to kill the connection
prematurely. You can experiment with the SSH options TCPKeepAlive,
and ServerAlive in the client to see if you can avoid it. However
more often than not the problem is caused by the router itself.
