Ok first just take a breath, you are getting nothing done by worrying. This guide is meant to try and help mitigate the effects of an attack that is in progresss. I have compiled a lot of the things that I do but it is very possible I have forgotten something. Please feel free to add suggestions at the bottom if you would do it a different way or if this works good for you.
This guide is not meant to take the place of a professional looking at your server but it should give you a very good idea of what is going wrong and point you in the right direction to solving the problem.

Eaccelerator is a PHP accelerator/encoder/caching utility that is based off of the old mmcache (which is no longer being maintained).
What Eaccelerator does is: it caches your PHP scripts so that the database is no longer being queried everytime someone needs a script. This is particularly useful for large forums, but pretty much anyone can benefit from it. Since these scripts are cached, you’ll notice a decrease in memory use and server load.

2. Type: pico -w /etc/xinetd.d/telnet
3. Change the disable = no line to disable = yes.
4. CTRL+X then Y then enter to save the file.
5. Restart xinted. Type: /etc/rc.d/init.d/xinetd restart
>Server security is as important as network security because servers
often hold a great deal of an organization’s vital information. If a
