Im using OpenSSH 3.8.1 and the directive TCPKeepAlive of ssh for the same
purpose as u noted.Hope this helps.
TCPKeepAlive : Specifies whether the system should send TCP keepalive
messages to the other side. If they are sent, death of the connection or
crash of one of the machines will be properly noticed.
However,this means that connections will die if the route is down
temporarily, and some
people find it annoying.The default is ``yes'' (to send TCP
keepalive messages), and the client will notice if the network goes down or
host dies. This is important in scripts, and many users want it
too.To disable TCP keepalive messages, the value should be set to ``no''.
