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.
- remote-host-ssh-user the user on the remote system the SSH connection is made on behalf of. IF missing, the UNIX user executing the command is implied.
