Getting High With Lenny
Author: randall •
Tags: debian, high-availability •
Comments: 0 Getting High With Lenny The aim here is to set up some high available services on Debian Lenny (at the time of writing still due to be released). Most of the documentation available for such a setup I found on the net are based on Xen but I prefer to use Vserver for the "virtualisation" because of its configurability, shared memory and cpu resources and basically the raw speed. DRBD8 and Heartbeat should take care of the availability magic in case a machine shuts down unexpectedly.

Simple Bash Script To Monitor Your Webserver Remotely On Different Ports
Author: marchost • Tags: linux, monitoring, programming • Comments: 2Simple Bash Script To Monitor Your Webserver Remotely On Different Ports Simple bash script to monitor a webserver on different ports (here smtp, dns, http & https but it can be customized); I'm sure there are over 100 available programs doing this but I wanted something with small memory usage. Also, I only wanted to be notified once, notifications are received by SMS on my cell. With the software I was using before, I was getting notified every minute until I could reach a computer and fix the problem or stop monitoring which was quite annoying.

Desktop Search In Ubuntu Intrepid (And Debian) In KDE 4.2
Author: Stephan Jau •
Tags: debian, desktop, ubuntu •
Comments: 1 Desktop Search In Ubuntu Intrepid (And Debian) In KDE 4.2 Ubuntu Intrepid 8.10 features an inbuilt desktop search. Unfortunately I never managed to get it to work right and I tried a lot of things. So I finally went on irc.freenode.org into the #strigi channel and asked for help. Lucky me Phreedom in there gave me a helping hand. Why Nepomuk doesn't work by default is still a mystery. I think this is related to Redland instead of Soprano. Unfortunately, as Phreedom told me, the Ubuntu and Debian maintainers don't supply Soprano with the current builds. Also his recommendation is to use KDE 4.2 (Kubuntu 8.10 comes with KDE 4.1).
