SSH Tunneling on Centos
I want to setup a centos box dedicated to ssh tunneling.
I need to restrict the users so they can't do anything else but tunneling (running shell commands, browsing through the file system, seeing other users).
I see tutorials for ssh restricted to sftp and scp, but nothing for restricting users to tunneling only. Even the rssh does not have any mention of this. If I am misunderstanding how this is working, maybe someone can clarify.
If anyone has done this or has any ideas as to how to do this, please offer some advise or a guide that I can follow.
