Posts discussing Linux and related technology.
A DIY task leads to reflections on the tools we use.
It's been a long time since I wrote here. The earlier content you see here actually came from my previous blogs at veejoe-dot-com-dot-au and later viccross-dot-com, both of which for various reasons are... no longer available. So why relaunch? Well, mostly because I still have things to say! I have not decided exactly what yet, … Continue reading Relaunching… again
Ever since work issued me a Lenovo T61 and I installed Fedora on it, I have lamented the loss of something that X afficionados referred to as "Zaphod mode". By gluing together a few different software and hardware components I managed to get close to the old Zaphod mode days -- but first some background... … Continue reading DisplayLink and x2x brings back Zaphod mode
Earlier this year (30 March, to be precise) Oracle announced that Oracle Database 11gR2 was available as a fully-supported product for Linux on IBM System z. A while before that they had announced E-Business Suite as available for Linux on System z, but at the time the database behind it had to be 10g. Shortly after 30 … Continue reading Oracle Database 11gR2 on Linux on System z
The next phase in tidying up my user authentication environment in the lab was to enable SSL/TLS on the z/VM LDAP server I use for my Linux authentication (I'll discuss the process on the DeveloperWorks blog, and put a link here). Apart from being the right way to do things, LDAP authentication appears to require SSL or TLS in … Continue reading What a difference a working resolver makes
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
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
