A simplified way to securely move all the bits.

A while back, I wrote a post about setting up an L2TP/IPSec VPN on my home firewall/router. It required two daemons and a bunch of configuration that had hard coded IP addresses. While this solution used firmly-established practices (L2TP/IPSec), it felt too brittle. What happens when my dynamic IP address changes? Now I need to update config files, … Continue reading A simplified way to securely move all the bits.

LACP, VLANs, always stay connected.

I was bored last weekend, so I configured a two-port LACP bonded trunk from my FreeBSD-running NAS connected to my HP Procurve switch. Why? I could?

This scenario happens to me every time OpenBSD releases a new … Continue reading From 0 to an OpenBSD install, with no hands and a custom disk layout

Third time’s a charm? Gitolite, Git, Nagios, and a bunch of hooks

I was hoping with my past posts on this topic, I would have enough examples to just copy-and-paste along to configure my Gitolite+Nagios monitoring setup. Not so true. It looked like there were semi-colon's missing in my past examples. After looking at the huge number of changes in Gitolite, I had to re-do everything. Not to … Continue reading Third time’s a charm?
