The keepalive options do not keep connections up. In fact, they do the
exact opposite. They will tear down the connection if the keepalive
time is met. This is meant to keep connections from getting hung if
the remote system crashes, or if the network is down for any length of
time. Check out the manpage for ssh_config for more information.
