Hi Vaibhav,

   1. Make sure you have "TCPKeepAlive yes" in your sshd_config file.
   2. If TCPKeepAlive is already yes, then add "ClientAliveInterval" in
      your sshd_config.

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.
