How can i reestablish a Tunnel if my localhost goes down?

i have 2 machines, Remotehost and localhost, on my localhost im running autossh to keep the tunnel alive in case of network problems.

autossh -M 20000 -L 3300: -R 3000: disp@ -p 80

but what if i need to reboot the localhost? how do i auto reconnect the tunnel then?

Put the command to establish the tunnel in some script which is executed on boot. You could use /etc/rc.local, you could write your own init script in /etc/init or /etc/init.d, or more elegantly, you could write a script in /etc/network/if-up.d. The last option executes the script after the network interface comes up.

Another simple option is to add @reboot autossh ... & to /etc/cron.d/autossh

This will look as: @reboot autossh -f -nNT -R 3269:host-providing:3269 firewalled-host & – nicoX Oct 7 '13 at 9:03
no need to add "&" at the end, -f already place the command in background – Pierre Maoui Apr 7 at 13:04
