disallow normal users from bind()-ing to ports

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



hi,

i want to regulate local users on our non-firewalled machines:

+ normal, non-system users (uid >= 500) shall not be able to bind to any port (so that they cannot run file-sharing applications, bypass company proxies/mailservers and what not);

+ there are certain IP aliases (say: 12.34.56.78 and 12.34.56.79) and of course 0.0.0.0 that should be able to be bind()-ed by normal users at all.

seeing that iptables now has --*-owner options, is it possible to achieve this goal with iptables? or do i still have to trap the bind() (or accept(), or listen()) syscall somehow?
