Do any of you have a sort of checklist that you go over or reference guide (self made or available somewhere) that you use when you are going to put an Ubuntu Server live to the evil Internet?
I am looking for something more specific than "close the ports that you are not using" or "uninstall the stuff you don't need". "Maybe something like sendmail is on by default. Take it out" or "chmod this file and that file for x reason." "Use so and so package to monitor for weird activities and so on and so forth" My Ubuntu system is working perfectly now (it has all the stuff I need)... I just need to make sure that a portscanner and some brute force crap will not take it out within 5 minutes of putting it live :) Recommendations? - Ragi
