[This is also partially an attempt to verify I can actually send to the 
NCLUG email lists due to the MIME type my emailer uses, hence the 
slightly out of date reply:-)]

I use these on my Linux-from-scratch server (openssh 3.7.1p2) and on 
Fedora Core 3 (openssh-3.9p1-7):

KeepAlive yes
ClientAliveInterval 30

This way it applies to all connections. I'd guess Client... tells the 
server to send the keep-alives, and Server... tells the client, thus 
only affecting outbound connections from whatever box the config option 
is set on?
