Is this a hack Attempt?

[Rushster]

We have been having all sorts of problems with hackers recently and the boards have been a prime target and they have succesfully changed stuff in Vbulletin. I started getting these reports from VB last week and I want to know if this is a hack attempt...

Database error in vBulletin :

mysql_connect() [<a href='function.mysql-connect'>function.mysql-connect</a>]: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
/var/home/sitename/public_html/includes/class_core.php on line 273

This error means either MySQL crashed, it's not running or it can't find the socket. You need to contact your host about this. Here is more info on this error:

MySQL 5.1:

MySQL 5.0:

MySQL 3.23, 4.0, 4.1:

These all seem to refer to Windows issues. The server is Gentoo so not sure if any of those notes apply below?

This is a server issue as I posted.
