Adventures in IPv6 land

I’ve spent the last week experimenting with IPv6; it now means that my whole home network and this website run over IPv6 as well as IPv4. As I’ve spent a while playing with this technology, I thought I’d write my notes up here in the hopes that it will help someone else.

SGI Irix packages

I have finally got a working build environment for my SGI IRIX systems (an R14k Fuel and a dual R12k Ocatane2) and have packaged some open-source software for the fantastic Nekoware project.

Solaris 11 Review

Xenserver snapshot and template based backup script

We have recently started using Citrix Xenserver in production at work (fantastic product, see my review for more information) and needed a simple backup solution. Our VMs run from an iSCSI SAN and are backed up daily through various methods - e.g. Bacula for the Unix/Linux systems. However, we wanted the ability to quickly roll back to a previous VM snapshot, and get up and running quickly if our SAN failed for whatever reason. Our solution was to create a large shared NFS...
