It would be nice to see some sort of Perfect Server setup with the very bare minimum install of an os (deb or ubuntu server) with and IDS setup (snort with the addition of Snorby frontend, barnyard2, suricata and pulled pork) as well as a configurable firewall (IPCop, etc) and webfilter (squid) rolled into one install. The detailed tutorials on the web are somewhat outdated.
Hopefully someone out there can shed some light.
