| That depends on which ssh implementation you're using. If it's
| openssh:
|
| $ man sshd_config
| [snip]
| ClientAliveInterval
| Sets a timeout interval in seconds after which if no data has
| been received from the client, sshd will send a message through
| the encrypted channel to request a response from the client. The
| default is 0, indicating that these messages will not be sent to
| the client. This option applies to protocol version 2 only.
|
| PuTTY can do this on the client side (Connection->Seconds between
| keepalives)

This did not help. Anyway, I got a round about way of handling this. I
am now using port forwarding (port 22) while establishing the first
ssh connection. Subsequest ssh connections are made o my localhost. At
the same time I keep a script running on the first ssh connection that
prints something on the screen every 10 minutes to keep the connections
alive.

I no longer have to worry about idle connections timing out as there is
only one connection and the script keeps it alive.

I know that it is a crude solution however, it might just help others
with the same problem
