I'm trying to get gnu screen -X cmd line option to work with paste, to keep a ssh session alive. doesnt work!

anybody know howto get screen to send a command to the shell its displaying regularily... to keep the ssh session alive..

The idea was, get screen to send date cmd to my remote ssh sessions regularily... but cant figure out howto automate that...
If I get date into the buffer, paste command works, but have to do it my self defeating the goal.

maybe another terminal multiplexor can do that?

who uses screen? or is it old technology...

You can set an option in your SSH config (usually /etc/ssh/ssh_config) to do this - see the ServerAliveInterval in man ssh_config.
