My mate dropped around today with a little gift from a company that closed down.. a big mofo Dell server. Haven't had a chance to google it's specs properly yet but from a quick glance it's got 8 hot-swappable SCSI drives, 2 quick-remove power sources, and I think he said 2 x PIII-500 processors (yeh, not so crash hot) and 2gb ram. I don't plan to run anything big on this, obviously, due to how old it is.. but I would REALLY like to use it to practice/learn setting up webservers from scratch, so eventually I can build my own dedicated. I have no problems installing Linux, and putting apache/php/mysql on it.. what i'm more looking for help with, is any guides as to security-setup etc. What do I need to do on a virgin install of say Ubuntu, to make it safe to put this thing live online with some small play-around sites? Or to use it as an online testing ground for my development? Also how does one point a domain name at your own static IP? What do you use for nameservers etc?
