So I have a mac at work which I like to ssh into my linux box with something like this:
$ ssh -Xt user@mylinux
I can login and start any X11 apps on my linux box no problem. But after 15 minutes or so, I come back to a session (ssh is still running and connected) and I get:
$ xterm xterm Xt error: Can't open display: localhost:12.0
I've tried using
-o "TCPKeepAlive yes" or
-o "ServerAliveInterval 30", but still get the same behavior.
Is there something in ssh or on the Mac or my linux sshd conf that kills X-forwarding after a period of inactivity?
