backdoor
 

my buddie decieded to backdoor my server...what do i do find it or w/e and kill it

Start by checking if there's any rootkits installed.

Go to http://www.chkrootkit.org/ and grab the latest version - install it and run it on your box.

:)

Also it might be a good idea to disconnect from the world too until you find this backdoor. And I wouldn't call him your buddy from now on. :)
