WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! Those who regularly build and rebuild machines or virtual machines on a dhcp network will probably be faced with this quite often, this is due to the known fingerprint for the previous host being different to a new one which has aquired the same IP address. @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!

The recent release of the Raspberry Pi 2 uses a newer version of the ARM architecture spec, the ARM Cortex-A7 uses ARMv7 whereas the previous model ARM11 uses ARMv6. The great thing about this is the majority of Linux distros already provide an Image for this architecture. More importantly, Fedora already have images. There is a slight caveat to the above statement however, that being they won’t just work with the Pi 2.

Monit is an application I’ve been meaning to setup for a while, I was first made aware of it from a chap I had the pleasure of talking to at OggCamp this year, he seemed to use it to the n’th degree to monitor files and services within docker containers to ensure a development environment was as it should be. This was far more than I really needed, but the monitoring of services definitely caught my attention so I set about installing and configuring.

I’ve been meaning to write this post for some time, but things have been a little hectic recently. That said I really wanted to write something, even if it is a little short, about Barcamp Manchester. The event took place over the weekend of 18th & 19th October and was just a fantastic weekend. After a fairly decent break from the Barcamp scene, Manchester really came back and did it justice.

I thought I’d finish off the year with a bit of reflection, overall it’s been a pretty good year in both camps of my life - the geek/tech and the family side. Obvious highs of the year include: Birth of my second child, Alfie. OggCamp 13 LinuxCon Europe Barcamp Blackpool RossLUGs 3rd year - some fantastic meetings this year. It certainly has been a full on year. It’s been a really tech filled year, as since moving house last September I’ve had my own space for all my tech which is a real bonus.

Whoa I’m getting a bit slow here! After the full on weekend of OggCamp my marathon continued up in Edinburgh for LinuxCon Europe 2013. Unfortunately my plan of heading up straight from OggCamp was scuppered, but I set off first thing on Monday morning. I decided to stick with driving after toying with the idea of getting the train. Glad I did, the Edinburgh park and ride system is brilliant! Parked up at Sheriffhall which allowed me to stay up to 7 days, perfect.

Although it’s been over a week since I returned from both these events I thought I better put a little something up about them and the experiences I had there. Unfortunately Oggcamp and LinuxCon followed each other directly this year, so it meant a lot of heaving about over the course of about a week. Here’s part 1 where I will detail my time at OggCamp. The event I look forward to all year, took a little longer to arrive this year due to it being moved to October (Oggtober?

I wouldn’t normally write about this kind of move, but I’m in a position where I feel I have to. A little over a year ago I made a decision to move from Fedora to Ubuntu, it wasn’t a decision that was easy after all I have been using Fedora since its first release, and Red Hat since around version 5. Needless to say I was (and still am at heart) a die hard Red Hat fan.

Here’s a (very) quick howto showing how to get GlusterFS up and running on Fedora. Its probably better situated on a distro like CentOS/RHEL, Ubuntu Server LTS or Debian stable but where’s the fun in knowing it won’t break? Most of these commands are transferrable to other distros though, its Fedora centric due to the use of yum, selinux and systemd (systemctl). Pre-requisites: 2x (or more) servers running Fedora, I used 18 in this example but i’m sure it shouldn’t change a great deal for newer releases.
