I’ve just written a module for Nagios that will determine if the currently running kernel is the latest kernel available on the system. It will not tell you if there is a newer kernel in a yum repository or similar. The main gotcha is that you need an RPM-based system for my script to work,Continue reading “Checking for the latest kernel with Nagios”

Changing the verbosity of wpa_supplicant on Ubuntu
Sometimes you need to change the log verbosity of wpa_supplicant for debugging purposes. First check which log verbosity you are currently running with. ps -ef | grep wpa_supplicant | grep -v grep -d represents verbose -dd represents extra verbose To change the log verbosity, edit /usr/share/dbus-1/system-services/fi.epitest.hostap.WPASupplicant.service and add -d or -dd as appropriate. Example: [D-BUSContinue reading “Changing the verbosity of wpa_supplicant on Ubuntu”
An error I don’t want to see
Is it just me, or is this not the kind of error message you want from a company that handles your bank and debit card details?
DV editing on Fedora
Recently, a friend asked me if I could copy her home videos from a miniDV tape onto a DVD. I said sure, OK, and if she lent me her camcorder I’d be able to get it done. I’ve never actually used miniDV before, and I’ve only ever tried to process video on Linux a handfulContinue reading “DV editing on Fedora”
Web statistics with AWstats
A few months ago I set up a website, Memories of Korea, to showcase some slides I inherited. Naturally I was keen to find out how many visitors I’d had, so I set about finding something that could draw pretty graphs. Based on my experiences setting up website statistics with AWstats, I’ve now prepared aContinue reading “Web statistics with AWstats”
Monitoring AQL SMS credit with Nagios
Further to yesterday’s post about setting up SMS alerts from Nagios, I decided I wanted to monitor how many SMS credits I have left in my account. AQL provide a way of finding out via an HTTP request, so I set about writing a perl module to check and return the result to Nagios. N.B.Continue reading “Monitoring AQL SMS credit with Nagios”
SMS alerts with Nagios
In a previous post I mentioned how easy it is to increase functionality in Nagios. Today I was asked to set up SMS alerts in Nagios, as well as the existing email alerts. I am by no means the first person to write about this, but this post is intended to be a start-to-finish guide,Continue reading “SMS alerts with Nagios”
On Nagios
The things I’m about to say will almost certainly be common knowledge to anyone who has used Nagios before, but I’ll say them anyway. In short, Nagios is a network/server monitoring tool. It’s web based and can monitor almost any network device. It comes with dozens of modules included, to monitor things with something asContinue reading “On Nagios”
An ugly fix
My home server seems to have developed a problem where its internal-facing network card “jams up”. It still keeps its IP address and everything looks normal, but in actual fact no traffic passes through it, cutting all my LAN hosts off from the Internet. Restarting iptables, network services or anything else doesn’t help. The onlyContinue reading “An ugly fix”
My crazy partition setup
My requirements When I built this computer back in January, I had carefully considered the RAID storage configuration. My requirements were basically: Must dual boot Fedora and some flavour of Windows (unfortunately) Fedora must have a redundant /home partition, as it holds my most important data Windows must have a fast Media (aka /home) partitionContinue reading “My crazy partition setup”
