I made a somewhat cryptic tweet a little while ago about how I spent a crazy-long period of time researching what was, I believed, the next-big-thing in DNS resolution for IPv6 (or so my 2002 edition of "IPv6 Essentials" told me). I could not work out why I saw nothing about A6 records in any … Continue reading Another IPv6 instalment (subtitled: Watch Your Tech Library Currency!)
A little while back I did an "emerge system" on my VPS and didn't think much more about it. First time back to the box today to emerge something else, and was greeted with this: >>> Unpacking source... >>> Unpacking traceroute-2.0.15.tar.gz to /var/tmp/portage/net-analyzer/traceroute-2.0.15/work touch: setting times of `/var/tmp/portage/net-analyzer/traceroute-2.0.15/.unpacked': No such file or directory ...and the … Continue reading Another round of Gentoo fun
Two of the four keynotes at LCA 2011 referenced the depletion of the IPv4 address space (and I reckon if I looked back through the other two I could find some reference in them as well). I think there's a good chance Geoff Huston was lobbying his APNIC colleagues to lodge the "final request" (for … Continue reading IPv6: SSDM?
For some time I've been feeling moody and generally unhappy. My ability to become frustrated with things that go wrong is ever-increasing, and my tolerance fuse seems to be ever-shortening. Co-incident with those feelings was the real physical manifestation of almost constant weariness -- waking up tired, never-ending back and shoulder pain, and so on. … Continue reading Burnt out
On Saturday (a couple of days ago as I type this) I volunteered to assist the cleanup in Brisbane's suburbs -- the city council organised volunteering locations where you could sign up and be transported to places that needed help. The process was well organised, except at the location I went to where the buses … Continue reading My flood volunteering day
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
