Centos - Restrict sshd to only tunneling
I'm new to the whole tunneling thing...
I am putting together a centos box that I want to allow users to tunnel through to surf the Internet. I want to disable everything else (shell access, ability to view other users and the file system etc...).
I searched on google and found a few suggestions of using a jail and using rssh.
My question is that what is the simplest way to set this up? I have no experience in chrooting a service to a restricted directory. Maybe someone knows a way to set sshd up so that it deny the ability to use the shell, and just creates a tunnel.
If someone can point me into the right direction or some how-to's, I would greatly appreciate.
