it should, but i havent played with it. i found this tho:

For ssh2, you can choose the time in sshd_config by setting the
ClientAlive* options.  For ssh1, you need to tweak the system timers
on either the server or client system; this is of course system-dependent.

ClientAlive* are ssh protocol keepalives: the server and the client
exchange encrypted messages to test and maintain the connection. This
is more useful than tcp keepalives in some applications.

Checkout "man 5 sshd_config" and look for "ClientAliveInterval" and  
"ClientAliveCountMax".

might be worth playing with.
