Overview

OpenSSH can be used to tunnel traffic from the local host to a remote host you have an account on.

Setting a Tunnel from a Local Port to a Port on a Remote Host

ssh -f -N [-p <remote-host-ssh-port> -i <identity-file>] \
  [remote-host-ssh-user]@<remote-host-address-on-which-ssh-is-exposed> -L <local-port>:<remote-host-interface-to-forward-to>:<port-on-remote-host> 

The "-f" option tells ssh to go to background.

The "-N" option tells ssh to NOT execute any command on the remote system. If "-N" is omitted, the ssh tunnel will establish AND login.

The meaning of other arguments is the following:

  • -p <remote-host-ssh-port> may be used to specify a non-standard SSH port, if the SSH daemon on the remote host was configured to listen on a port other than 22.
  • -i <identity-file> may be used to specify a non-standard identity file, or the identity file for the remote user the connection is made for, if different from the local UNIX user that executes the command.
