SSH tunnel broken

textomat · 09-15-2004, 12:20 PM

I've set up ssh tunnels to the mysql server from one machine to the other. It works fine but after a few days the connection breaks and I have to reissue the command. How can I set up a ssh tunnel to last for ever.

Here's my command which I run as root. sshtun is the user I open the tunnel as..

su - sshtun -c 'ssh -N -L 6306:localhost:3306 xx.xx.xx.xx &'

Try adding keepalive options to your sshd_config file. The options you use are partially dependant on your version of ssh. see that sshd_config file man page for more details.

You may also want to consider running the tunnel a service using daemontools so that it is automatically restarted if the connection does drop for any reason.
