Firewall, etc, box

Posted by & filed under Some Links.

After salvaging a fairly new mobo, ram and hdd from a mini-tower I found abandoned next to a recycling bin a couple of weeks ago, I’m looking to put together a firewall/gateway/misc server box for kicks and educational purposes.

After a Wikipedia/Google trawl, the options I’ve come up with for a suitable set-up are Endian, eBox Platform , SME Server and pfSense.

I’m wondering if anyone has comments on these or alternative suggestions? Thanks!

“The term ?warwalking? isn?t used very often, but the Ekahau HeatMapper adds a new tool to the pod bound hacker?s arsenal. The tool maps out wireless access points as well as their signal strength within a facility. A test of the HeatMapper on a map made with AutoDesk Dragonfly accurately determined the location of a router within 3 feet and helped tune the angle it needed to be at for maximum range.” link
