If you have a UPS, it’s probably worth paying attention to the temperature reading if it reports such a thing. My APC Smart-UPS 1000VA suffered a failed battery which wasn’t totally unexpected given I had last replaced it about two years ago. While I was awaiting the replacement RBC6 battery, I had a poke about [...]
I’ve been quite keen on getting IPv6 connectivity to my hosts, although I’m currently lacking either a home internet package or hosted server where there is native connectivity. Thankfully there are enough free tunnel providers available which work fine as a workaround. I’m using SixXS for two tunnels; one to my home network and another [...]
I hit a weird issue today, I have Apache configured as a reverse proxy using mod_proxy_balancer which is a welcome addition in Apache 2.2.x. This is forwarding selected requests to more Apache instances running mod_perl, although this could be any sort of application layer, pretty standard stuff. With ProxyStatus enabled and pushing a reasonable amount [...]
I had a need to create some CentOS 5 hosts on Amazons EC2 platform, and while there’s nothing stopping you from reusing a pre-built AMI, it’s always handy to know how these things are built from scratch. I had a few basic requirements: I’ll be creating various sizes of EC2 instances, so both i386 and [...]
I wanted to install a Fedora 13 machine as a paravirtual domu guest on our CentOS 5.5, xen 3.4.2 host. I also wanted to provision it using koan/cobbler. I ran into a few problems along the way, but I got there in the end! Firstly, createrepo in CentOS 5.5 does not work with either the [...]

It’s a typical situation, the developers develop on their own boxen, they only start to integrate their code on on the production platform 3 hours before the deadline. And then the problems start, the typical “But it works on my system” , “its you…
Recently I downloaded RedHat 6 Enteprise beta (RHEL6). I wanted to install it as a Xen guest (DomU) on top of an existing Centos 5 Xen host. Unfortunately it did not work out of the box. I ran virt-install –prompt on the Xen host which let me install RHEL6 however when the install rebooted I [...]
It seems that several people have been having problems getting Dell OMSA 6.2 to work correctly on CentOS 5.4 x86_64. Specifically, the software does not detect any storage controllers, and therefore also doesn't find any disks. eg. [root@b034 ~]# omreport storage pdisk controller=0 Invalid controller value.
