IRC sockets

Hello php-general, I got a little problem, if you can help me or point me to good links about it, thanks! problem is that, i have server, and i don't allow shell accounts on it. Now one guy came up with some PHP script that launches bot into IRC with my hostname and everything, and stays like a bot, listens for all commands. well i deleted the account but i don't want any other people doing that. Now how i can protect fsock open for 6667 port or other irc ports? I don't want to disable fsock, because some other people might need to use it for other reasons. or if there is no other way, do i just modify php.ini to be without fsock. or what do i do? thanks for help. P.S people started getting smarter and learning new ways getting shell access to irc without shell :( -- Best regards, Mantas mailto:Mantuks@attbi.com
