I sometimes find myself doing web app development on another machine via an SSH
connection. If I have the server running on port 3000, then I like to use
SSH’s port forwarding feature so that I can access
localhost:3000 on my
$ ssh firstname.lastname@example.org -L 3000:localhost:3000
What if I have two different servers running? I’d like to port forward both of them — that way I can access both.
SSH allows you to forward as many ports as you need. The trick is to specify
-L for each.
$ ssh email@example.com -L 3000:localhost:3000 -L 9009:localhost:9009
