The cmdlet itself is written in C# and utilises a centralised LAMP backend as a repository and director.
Upon install psFetch will [...]

This post has no real merit its just that the Error message caused me to actually laugh out loud:

Last H.O.P.E and Tackling the Debian OpenSSL Issue

July 30th, 2008 by Gareth Llewellyn

Well I’m back from my trip to New York and I’ve brought back a couple of things.
With the most tracks HOPE has ever had I was truly spoilt for choice but I spent most of my time [when I wasn't showing our US friends how drinking should be done] visiting talks that had potential datacenter [...]

Windows Server 2008 With Exchange 2007 - In Production

May 29th, 2008 by Gareth Llewellyn

Considering how bleeding edge the majority of my projects are I’m a little behind the curve on this one but I’ve finally managed to move all my Windows Servers across to Windows Server 2008. This includes the Domain Controllers, Web Servers and most critically the Exchange servers.
This post is going to be cut into the [...]

Benefits of Virtualisation For Training

February 24th, 2008 by Gareth Llewellyn

Working in a Data Center brings with it various challenges that you wouldn’t normally find in most other jobs; we come across demanding solutions, ingenious ‘hacks‘, impressive software and outright weird errors.
Once we’ve crossed a particular hurdle then we need to go about disseminating this new found information to the other SysAdmins.
So far [...]

Leveraging Virtualisation To Fight Spam

December 23rd, 2007 by Gareth Llewellyn

A few weeks ago I ‘inherited’ a frontend anti-spam solution that was getting crushed under the weight of the Christmas run-up. Emails were taking up to a week to arrive at the back-end system and a lot of spam was getting through too.

VMWare Virtual Center Errors

September 4th, 2007 by Gareth Llewellyn

Yesterday I had a nasty case of Y-splitter failure (in future I’m just going to upgrade the PSU rather than go though this again) which caused all four of the 320Gb disks of a RAID5 array to suddenly disappear.
Windows didn’t like that and hung, VMware Virtual Center disliked it even more. Once I recovered the [...]

Monitoring WMI From Linux via a C# Daemon and PHP

July 1st, 2007 by Gareth Llewellyn

WARNING: I am not a programmer, I don’t claim to be so it is quite likely that the code you will find here will horrify you!
As part of my drive to monitor as much as possible of my systems I realised that creating an intermediate daemon for WMI would allow me to access some of [...]

Additional Logwatch Scripting for Postfix and Amavis

June 20th, 2007 by Gareth Llewellyn

First thing in the morning I like to have a quick browse through the Logwatch output for all my servers (or at the very least the ones I know are critical / the ones that have been giving me trouble) and for the most part the data is always quite concise and extremely useful. However [...]
