A while back I wrote about the worst cabinet ever. Maybe this one isn’t as spectacular to behold, but there is a Cisco switch under all that spaghetti. There are also two PoE power injectors for wireless access points. All this is in a wooden cupboard and it was roasting hot. You can see thatContinue reading “New worst cabinet ever”

Samba fixed!
For those who have been following the issues around Samba suddenly breaking upon upgrade, I’ve now got to the bottom of it. I’ve updated the original post with details, so if you wish to leave comments, please leave them on that post.
Upgrading to Windows 7
I don’t use Windows much, except on my home media centre. For a while I’ve been running Vista and I’ve generally been impressed with the Media Center application. I read about Windows 7 and was pleased to hear about the Ultimate Steal protomotion for students (and those with .ac.uk email addresses). The high prices ofContinue reading “Upgrading to Windows 7”
Various Nagios plugins
I’ve now written several Nagios plugins and submitted them all to MonitoringExchange. Here’s a quick summary: check_temper for monitoring the temperature with a TEMPer USB thermometer check_kernel for checking that the currently running kernel on an RPM-based system is the most recent installed kernel (not necessarily the latest available kernel in the repository) check_aql_balance forContinue reading “Various Nagios plugins”
Nagios plugin for TEMPer USB thermometer
As I said in a previous post, I finally got my TEMPer USB thermometer to work on Fedora, thanks to a patch by Tollef Fog Heen that has now been incorporated into the Fedora kernel. I’m not familiar with C so I only made minor tweaks to Tollef Fog Heen’s code, which returns a temperatureContinue reading “Nagios plugin for TEMPer USB thermometer”
TEMPer USB thermometer on Linux
Some time ago I bought a cheap USB thermometer called TEMPer. I was disappointed to find that it didn’t work on Fedora. It would only work on Windows using a poor piece of proprietary software. I eventually found the blog of Tollef Fog Heen, who had managed to get his TEMPer to work. Unfortunately hisContinue reading “TEMPer USB thermometer on Linux”
Readership demographics
I’ve been using awstats to collect statistics on visitors to my blog since July 2009. I’m a sucker for pretty graphs, so I’ve made a few 🙂 Operating systems First and foremost, which operating systems are visitors running? Good to see a disproportionately large number of Linux users! It’s probably a self-selecting audience to aContinue reading “Readership demographics”
Guide listings in Vista MCE for ITV channels
When I get my Vista-based Media Center to scan for FreeView channels, it finds them all correctly. When I go to add listings, I choose my region and it fetches them. But ITV1 and ITV2 both lack listings – despite the fact that the listings in question appear to be available. There’s a tweak youContinue reading “Guide listings in Vista MCE for ITV channels”
Escaping usernames during RADIUS accounting
Today I encountered a problem in my FreeRADIUS setup. Usernames can be sent to my RADIUS servers as a simple username (e.g. jonathan) or with a realm prepended (e.g. DOMAINjonathan). When a username with a realm gets sent to a RADIUS authentication server that is doing MSCHAP, the domain is automatically stripped and you neverContinue reading “Escaping usernames during RADIUS accounting”
Upgrading samba breaks it
I have a samba fileserver which has been happily running for a couple of years with identical config but on different versions of samba, and on Fedora and CentOS. The latest incarnation was running samba 3.2.11. But the other day, my samba package was upgraded to 3.4.1 Samba shares on the server immediately stopped workingContinue reading “Upgrading samba breaks it”
