How can I close SSH tunnel gracefully?

  • 772

I have open tunnel with

ssh -2 -N -L 5001:localhost:1019 [email protected]

The tunnel is working good, but I have to Ctrl+C or Ctrl+D to force quit the tunnel. How can I close the tunnel gracefully?

ssh ssh-tunnel

  1. SSH has a escape sequence to reset the connection, it will probably work for what you want. Press enter, then ~., yes it's enter tilde-dot.

    It also works when you have a hanged SSH connection (like a connection that timed out but didn't close), just press enter (I have an habit to press it more than once) and the tilde-dot sequence to close it.

    Some useful ones:

    • ~? will show you all the escape sequences available
    • ~^Z that's control+Z will suspend your SSH session (you can get it back with fg)

  2. Close whatever is connected with the other side through the ssh connection first.
