*** This is the complain from the people that host our server:

We have received a complaint that your server is currently running an
IRC bot, which in itself is not a problem. But this Bot is either
attacking, or trying to gain illegal access to other servers on the
net. It might also be possible that this Bot is acting like a Worm or
Trojan Virus.

Skills required:
Apache, Linux, Plesk, System Admin, Web Security
