SSH Tunneling (SSH port forwarding)

tunnel.md

Opening SSH tunnel in a shell

    ssh -L 3000:localhost:3000 -N remotehost

-N - for "run no command". To create a local port forwarding, pass the -L option to the ssh client

    ssh -L 3000:localhost:3000 -N remotehost &

& - for send that SSH process to the background

MongoDB port forwarding as example:

$ ssh -N -L 27017:127.0.0.1:27017 remotehost &

Close: find process with ps command then kill

    kill $!

or

    kill %1
