I recently set up a CentOS Linux OpenVPN server for a small office, and this is a complete howto writeup of the process. These instructions contain everything you need for configuring the server (including firewall rules!). Also included are complete instructions for setting up both mac and windows client machines.

I was recently stumped by an odd incoming network connection hang problem on a linux server. This is a writeup of how I troubleshot the issue and eventually fixed it.

I recently had to deal with a dovecot imap server bug which results in invalid X-UID headers in mbox mail spool files. The fix is somewhat annoying because you have to both upgrade dovecot and delete the invalid headers from mail spool files. This page is a writeup of the process I used, including a shell script to help automate it.

I finally got around to upgrading my Linksys WRT54GL home wireless router to an open-source firmware, dd-wrt. This was more confusing than it should have been, mainly due to the large number of options available for wireless router firmwares. However, once I got that all sorted out the actual install was surprisingly easy and satisfying. This howto contains my notes on that process.

An excellent tutorial on how to configure secure remote backups using rsnapshot and root ssh. Includes details on all the steps necessary to secure your root ssh keys and limit access.

I recently had to migrate a CentOS 5 system from a single hard drive to a mirrored RAID configuration. Since I had set up the system with LVM originally I was able to do this (mostly) seamlessly while the machine was in production. This howto details the steps I took and the commands necessary to migrate the system.
