If some of webserver clients are more of a developer kind and love to use SSH even though Im having second thoughts about allowing SSH access at all. If I would allow SSH Jailed Shell to all my webserver clients. What can actually happen? How to monitor them and are there any possible way to limit commands they use? eg. I dont want them to run gameservers on webserver. Or start Ventrilo or Teamspeak server just because they have Shell access. So how would it be safe to allow it?
