Sometimes I need to recompile software packages on Ubuntu, for instance because of a special feature. I use the resulting packages on a number of servers, but manually using dpkg to install muickly becomes a pain if the number of machines becomes significant. Therefore I have created a custom software repository that can be used… Continue reading Custom Ubuntu software repository

Music with Ubuntu
Play it on remote HiFi speakers After several Linux trials and errors over the last couple of years, I finally switched to Ubuntu Gutsy as my main OS on my laptop. The user experience of current Linux distro’s is good enough, and Linux does not (yet) suffer from the massive amount of malware and virusses… Continue reading Music with Ubuntu
Multiple full VM backups using VCB, rsync, OpenSSH and VSS
The problem Our shiny new VI3 setup works really well, but the backup chapter still needs work. I P2V-ed all our Linux boxes to VM’s, so the existing rsnapshot file level backups still run. So far so good. But, in addition to file level backups, I also want full VM backups, each day, both on-site… Continue reading Multiple full VM backups using VCB, rsync, OpenSSH and VSS
Google Mini rack rails
Recently we decided to ditch the Mnogosearch search-engine and go for a Google Mini. We haven’t configured it so I have no idea if or how it works. What I do know, is that you don’t get any rails to put it into a 19 inch rack. Since Google does not sell separate rails, you’re… Continue reading Google Mini rack rails
mount: special device /var/run does not exist
While P2V-ing an Ubuntu 6.06 server with my warm-cloning P2V method, I ran into a strange problem when booting: The exact text of the error is: mount: special device /var/run does not exist mount: special device /var/lock does not exist mount: wrong fs type, bad option, bad superblock on /dev/shm/var.run, missing codepage or other error… Continue reading mount: special device /var/run does not exist
Manual P2V of Debian Sarge
Now that we at TERENA have a new and shiny setup of VMware VI3, I had to migrate several of our Debian 3.1 Sarge servers. Some of them had custom kernels, because of specific hardware. This virtualisation process (P2V, or Physical to Virtual) is properly supported for the Windows platform using the VMware Converter software.… Continue reading Manual P2V of Debian Sarge
Configuring a static IPv6 address in Windows 2003 with netsh
For each network interface, Windows 2003 Server offers a GUI to configure IPv4 parameters (Internet Protocol (TCP/IP)). After installing IPv6 there is a new item Microsoft TCP/IP Version 6. When selecting that, the “Properties” box becomes grey-out. This means that there is no GUI to configure IPv6 parameters. You will have to use the netsh… Continue reading Configuring a static IPv6 address in Windows 2003 with netsh
Upgrade PostgreSQL after upgrade to Ubuntu-7.0.4
Ubuntu-6.10 (Edgy) has PostgreSQL-8.1.6 installed. When upgrading to Feisty, PostgreSQL 8.1 is not supported anymore. When booting into Feisty, 8.1.6 still works, but you should manually upgrade to 8.2.3. After a few upgrades, this seems to be the right way (at least for most of us, that just run 1 cluster): apt-get install postgresql-8.2 pg_dropcluster… Continue reading Upgrade PostgreSQL after upgrade to Ubuntu-7.0.4
Array sorting but without articles
Sometimes you want to sort an array in PHP, but exclude certain words. I once needed this to sort a list of artists and bands. It is very common for bandnames to have articles in front of them. When sorting those, it feels more natural to leave those words out, so that “The Doors” would… Continue reading Array sorting but without articles
Workaround for “empty-contact-list” problem in Nokia PC Suite
I recently lost my good-old Nokia 6100 mobile phone. Luckily, my provider KPN gave me a new one for free, a Nokia 5500 Sport. After a few weeks I found my old phone and was very happy that I had my 150+ contacts back 🙂 The Nokia PC Suite software made it look like I… Continue reading Workaround for “empty-contact-list” problem in Nokia PC Suite
