At work, I have a pretty beefy workstation (a Dell OptiPlex 990 with a 3.4GHz Intel Core i7-2600 and 8GB RAM running Fedora 16) that I usually run a few VMs on as my test/development environment. I usually reboot my machine every other week or so, and start …

Since I have most of my public-facing stuff hosted with Linode, and I have a monthly bandwidth cap (albeit one that I’ll probably never come close to), I decided that it would be a good idea to add my monthly bandwidth usage to my monitoring system. Luckily, Linode offers …

Lately I’ve been playing around with the VMWare vSphere SDK for Perl, since the new job uses a bunch of VMWare stuff (and I’ve been starting my foray into Perl as a new language, and am amazed by the massive number of modules out there). As much as …

As you may know from former posts, this blog (WordPress-powered) and a few MediaWiki sites that I have use the excellent PHP-based GeSHi syntax highlighter. Today I was writing a post that includes some Icinga (Nagios) configuration snippets. After a quick search, I found a Nagios language file …

I’ve been doing some work on icinga (a Nagios fork) and wanted to implement notification via AOL Instant Messenger (AIM), since I’m almost always signed on when I’m at a computer. Unfortunately, most of the scripts that I could find use Net::AIM::TOC which implements a …

I recently discovered the petit program for log analysis. It’s a simple tool to pull out useful information from syslog logs in a variety of ways. I’ve only used it a few times so far, mainly on logs from problems I’ve already solved but didn’t know …

Since I always seem to forget this wonderful feature of GNU screen (probably one of the pieces of software I use the most every day)…

• To split the current region horizontally into two equal regions: C-a S
• To switch between those regions: C-a Tab
• To close all regions but the …

Both my last and current jobs use MediaWiki for internal documentation. As always happens, some of this documentation will inevitably get out-of-date, or totally deprecated. As is also the case, many times when we’re looking for docs in the middle of an incident, we don’t have the time …

I’m in the process of moving all of my public-facing services, currently hosted on a single Linode, to a new virtual machine (still with Linode, of course, just a new CentOS 6 VM). Of course, I’ve got a lot (about 60) of DNS records, spread across 8 domains …
