I was four or five years old when Brisbane encountered its last major flood disaster in 1974. I have vague memories -- so vague I don't know for sure if they are real or imagined -- of looking out the front window of the house we lived in at the time and seeing the water … Continue reading Floods in Brisbane

I've been using Nagios for ages to monitor the Crossed Wires campus network, but it's fallen into a little disrepair. Nothing worse than your monitoring needing monitoring... so I set about tidying it up. Network topology changes, removal of old kit, and some fixes to service checks no longer working correctly. One of the problems … Continue reading Nagios service check for IAX
I posted on my developerWorks blog about an experience I had sharing an OSA port in Layer 2 mode. Thrilling stuff. What's more thrilling is the context of where I had my OSA-port-sharing experience: my large-scale Linux on System z cloning experiment. One of these days I'll get around to writing that up.
It's been ages since I did an update on the main network machine here, and I bit the bullet over the weekend. 250+ packages emerged with surprisingly little trouble, and all I was left to do was build the updated kernel and reboot. I usually end up with something that doesn't restart after the reboot, … Continue reading Asterisk and a Patton SmartNode
I recently spent a week in Amsterdam, attending the Novell BrainShare conference there. This visit to Amsterdam was unlike any I've made before: certainly unlike the last one, where I barely made it halfway from the airport to the city and was there for less than 40 hours. Firstly my arrival was disrupted by the … Continue reading Amsterdam trip report
With Apple's abandonment of PPC as of Snow Leopard, I began wondering what to do with the old PowerMac. It's annoying that so (comparatively) recent a piece of equipment should be given up by its manufacturer, but that's a rant for another day. Yes, we can still run Leopard until it goes out of support, … Continue reading ppc Linux on the PowerMac G5
I've been doing a lot of mucking around with KVM with libvirt (I keep promising an update here, don't I). In my desktop virtualisation requirements I had a need for presenting VLAN traffic to guests: simple enough, and I've done it before. You can do what I usually do, and configure all your VLANs against … Continue reading Network virtualisation
For a long time I've been managing virtual e-mail addresses (the ones you create when you sign up to a web service, so that you know where your spam is originating) using Postfix's LDAP alias capability. At the time I was still putting every bit of configuration I could into LDAP--particularly if it was user-id … Continue reading LDAP groups in Postfix
Since I've been back home now for almost a month, it seems silly to call these posts "travel updates". 🙂 With the experience of visiting le Viaduc de Millau still buzzing in my head, I pointed my trusty Peugeot back toward Montpellier for the journey to Germany. The run down the mountain back toward the … Continue reading Travel report: Driving to Sindelfingen
Seems like ages ago I watched that episode of Top Gear where they took a Ford GT, a Pagani Zonda and a Ferrari F430 from Paris to the Millau Viaduct. At the time, I didn't figure that I'd have any opportunity to see the bridge in the near future, but nonetheless subliminally noted it as … Continue reading Travel update: le Viaduc de Millau
