My Linux-based Large-Scale Cloning Grid experiment, which I've implemented four times now (don't ask, unless you are ready for a few looooooong stories), has three main components to it. The first, which provides the magic by which the experiment can even exist, is the z Systems hypervisor z/VM. The second is the grist on the … Continue reading Programming decisions

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?
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
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
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 had a failure of my Cacti system over the weekend, entirely caused by bad Gentoo emerges. Two different problems, both caused by bad upgrades of packages brought in from ~amd64 or ~x86, made Cacti colourfully dysfunctional for a couple of days.The first was an update to the spine resource poller, part of the Cacti … Continue reading Sometimes, Gentoo bites
I know I'm going to cop a beating on the Planet for this post, but here goes... For a long time I ran a desktop system built on Gentoo Linux. A while back I tried Ubuntu, and I've been running that as my desktop ever since. Every now and then, though, I feel an inclination … Continue reading Thinking of a Gentoo desktop
I've been running jabberd2 from ~x86 for ages. Tonight I went to make some config changes, and stopped and started jabberd using the init script like usual. Things were different though, as the init script didn't shut down all the Jabber tasks and I had to stop them manually. When I went to restart it, … Continue reading Gentoo + jabberd = aargh
I had some system problems yesterday. My VMware guests just stopped. Middle of the day and they just died. I tried to run the management console or even the command line programs, but they all failed with the infamous "VMware is installed but is not configured for this system..." message and the prompt to run vmware-config.pl. I re-emerged vmware-server … Continue reading Gentoo “hardened” multilib?
