comment How to forbid user to bind a socket on other than a certain address?
Tried in local, remote, changing ports... This time it works! Thanks! I'm curious, why 41 and 42 as marks?

comment How to forbid user to bind a socket on other than a certain address?
Cool, I took a time to understand it and it seems to make sense (it would not restrict the user to bind the port, but would cut all undesired connections). Bad part is I tried it in a VM and it does not seem to work. I did set up the filter (for a user x, allowing only port 1234), set up a server with the user x on the different port 1245 but nevertheless I am able to connect to that process from the outside. I made a screencast showing it... lasaña.rufian.eu/CPZS (link valid for a week)

Too overkill. All that user needs is a reverse SSH tunnel for his service to be available on the machine.

That would force me to restrict all users to create servers, but I want to limit only that user.

iptables owner module does not work for INPUT table (man iptables-extensions). I don't see how you could use this to forbid a user to bind a server. If you know, please write an example rule.
