OK, so I might have been a bit hasty to dismiss Centos in my last post – a couple of people have contacted me and told me about additional repos that I can use for rubygems etc – so as a brief interlude, here’s the instructions for getting MCollective and ActiveMQ up and running on Centos 5:
A few weeks ago I was at UKUUG and met an intriguing project (and it’s owner) called mcollective.
MCollective is a system that enables you to run queries across multiple servers in real time and have the responses come back to you in a speed you would only expect if you were physically at the console. In other words:- it’s f**king quick!
This post sets out to show you how to install it on Ubuntu Server (the instructions should apply to both 9.10 and 10.04 RC), the next set in the series will help you get it up and running across multiple machines!
There are a few dependencies that need to be installed before cucumber-nagios will work correctly:
And that’s about it…
OK, so I’m not the first to blog about this, however I’m using cobbler and puppet to automate the creation of VMs on my laptop for testing/staging purposes so I thought I’d blog about it here.
The aim is to use Cobbler to setup the base operating system and install puppet, then let Puppet take over and install and configure the rest of the system.
Twitter has the latest updates on safe-proxy servers for those inside IRAN wishing to get out and publish about the current events.
Current list is as follows (19:48 on Monday 15th June 2009):
218.128.112.18:8080
218.206.94.132:808
218.253.65.99:808
219.50.16.70:8080
WHOIS reveals that these IP addresses are NOT inside IRAN and therefore are unlikely to be shut down as part of the signal jamming referred to in a bbc post found @ http://bit.ly/11YBNo

There are calls for a DDOS on the Iranian Gov’t Servers. I think this is a bad idea as it is using fire to fight fire IMHO.

Just a quick post…
In the last two parts of this series I stated I’d be using Ethernet over Powerline (aka HomePlug) as the backbone for my media system.
I currently own two 14Mbps units and tests have rapidly shown that this is nowhere near good enough. Looks like I’ll have to upgrade to the 200Mbps units once I get paid and hope that it makes a difference. If it doesn’t, I think I’m going to have to go down the route of Wireless-AP’s flashed with OpenWRT and acting as bridge devices to get the DHCP/TFTP working for the media directors.
Hmmm, PXE over a flakey wireless CX – not good… :o(
In part one of this series, I outlined LinuxMCE and how amazing it was providing Home Cinema, VoIP Telephony, CCTV and home automation in one system for the price of a download and a few hours work. This article will help those who, like me, live in rented accomodation or cannot ask their local electrician to come and channel cabling ducts into the walls for some other reason, yet need to have a solid network cable running throughout the house.
I’ve been playing around with Home Automation and trying to get my audio/video around the house without honey-combing the walls for the last few years with varying degrees of luck and in this time I’ve looked at a number of solutions including proprietary hardware (too expensive!!), Microsoft Windows Media Centre Edition (expensive and it runs on Windows…) and MythTV/Music Player Daemon (free, but not always the easiest to get it working!
Two years ago, I found Pluto Home – a commercial solution that had an open-source base and ran on Debian. I played with it for a bit as the feature set was amazing (TV, Video, Audio and CCTV anywhere in the house as well as integrated VoIP telephony and some really cool stuff) but I ran out of spare time to explore it further. I’ve started to look into Home Automation and Media again and this time, instead of using Pluto Home, I’ve decided to settle for LinuxMCE. It’s based on pluto home and Ubuntu and there’s been a lot of development since I was using Pluto…
“The French national police force, the Gendarmerie Nationale, has spoken about their migration away from the Windows platform to Linux. Estimated to have already saved the force 50 Million Euros, the migration is due to be completed on all 90,000 workstations by 2015. Of the move, Lt. Col. Guimard had this comment: ‘”Moving from Microsoft XP to Vista would not have brought us many advantages and Microsoft said it would require training of users,” said Lt. Col. Guimard. “Moving from XP to Ubuntu, however, proved very easy. The two biggest differences are the icons and the games. Games are not our priority.”‘”
LOL @ “Moving from XP to Ubuntu, however, proved very easy. The two biggest differences are the icons and the games. Games are not our priority.”‘”
OK, so I tried to run the upgrade last night and I’ve ended up with a few issues. This could be my fault, however I did follow the instructions found on the debian website and had to resolve multiple dependencies.

Wasn’t that fun? :oP
