I’ve updated temper-mon and my Cacti templates to better work with the TEMPerNTC device, which has an external temperature sensor in addition to the internal one.
I graph the temperature of my server cabinet (at home) and colocation room (at work) in Cacti, using TEMPer USB thermometers. I wrote a handy guide to doing this last year.

Most of my really popular blog posts are how-to guides on complicated-but-useful procedures for the technical Linux user. Those users are the same ones who may read the date in the URL and say “Ewww, this was written three years ago, it must be totally outdated now!” I’ve decided to update the most popular posts to bring them up to date. This post is “Using host networking and NAT with VirtualBox“, version 2.0.
