# Paramiko by default sets the socket timeout to 0.1 seconds,
# ignoring what we set through the sshclient. This doesn't help for
# keeping long lived connections. Hence we have to bypass it, by
# overriding it after the transport is initialized. We are setting
# the sockettimeout to None and setting a keepalive packet so that,
# the server will keep the connection open. All that does is send
# a keepalive packet every ssh_conn_timeout seconds.
