The screen program, among other useful things, lets you keep an SSH session running even after you disconnect from SSH. Here’s how to use it.

SSH in.

ssh user@hostname.com

Once on the remote machine, set up a named screen:

screen -S myscreen

In another terminal, open another SSH connnection and start another screen:

screen -S mysecondscreen

You can see they are there by using, in either of the terminals,

screen -ls

This does NOT start screen, just lists the different screens.

You can now disconnect the SSH connections. When you reconnect, you can use

screen -r myscreen

or

screen -r mysecondscreen

to reconnect to the one you want.
