ssh client timeout

When I remotely login to other Unix servers with ssh, the connection closes after some period of inactivity. I've seen this problem on other OS and have had to adjust the keep-alilve time. Is there some way to do this on OS X? Thanks!

Add the following lines to ~/.ssh/config

TCPKeepAlive yes
ServerAliveInterval 45

The first ensures that your ssh client is, in fact, doing TCP keep alives, which it should by default. The second is a relatively sane value, in seconds, of the period of inactivity between client and server after which the keepalive will be sent.

Not sure if there is a setting on the client side - the ssh host that I access has a timeout set on the server side - which, from the server perspective is not a problem but a feature.

a crude way of addressing this would be to creating a small shel script that does something along the lines of send the output of an ls command to /dev/null every 10 minutes or so.

Add the following lines to ~/.ssh/config

ServerAliveInterval 45

Thas sounds like a better plan.
