How to automatically reconnect to lost SSH connections using autossh
My website has moved to a new address: hund.tty1.se
I’m a heavy user of SSH and one thing that used to bother me was the fact that when I suspended my computer I would (logically) loose the connection to all things connected via SSH. Manually reconnecting the same things several times a day gets old fairly quickly.
With the help of autossh you can automatically reconnect to lost connections. This is the basics and also how I use it:
$ autossh -M 0 -o "ServerAliveInterval 45" -o "ServerAliveCountMax 2" <user>@<host> -t "<command>"
ServerAliveCountMax will make the SSH client exit if it finds itself no longer connected to the server. And don’t forget to check out
man autossh for a lot more information.
