server terror

[mijnwebservice]

My only server with DA running on it.
Something happened last night wich made the server shut out everybody.

you cannot login to anything exept ssh.
rebooting is not possible (unless I press the famous reset button)
accessing the server trough any domainname isn't possible but by IP is.

if i look into the log files, it looks like the system was updating itself of something and gave the next error:

error: "kern.ostype" is an unknown key
after that, it denies permission for everything.

and what does this mean?

I suspect the worst ...

Run this from root:

netstat -a -v -p -t

You're looking for a connection to an ircd (irc daemon)

Chances are, you've been totally compromised and a reformat is in your immediate future.

I agree - sounds like it has been hacked. Hope you have made backups of your sites.
