When I heard the news that McColo had been pulled I wondered if we’d actually see a drop in Hostile traffic and Spam.
Turns out that there has been a massive drop in Spam levels coming through some of the filters I have dotted around the place.

With the initial tests over it was time to actually move over to ‘real’ IPv6 addresses.
After applying for a tunnel from SixXS it was time to set it up. Unfortunately none of my JUNOS or Cisco IOS images have IPv6 support so rather than buying another 2600XM I decided to use the Windows Server 2008 [...]

We already know that disabling IPv6 on a 2008 & Exchange 2007 server breaks things but what if we go IPv6 only?
IPv6 Only Domain Controllers:
The installation didn’t cause any trouble but after initially logging on and running a DCDiag we see this:
It turns out that the install of the DNS Server had set the NIC’s [...]

IPv6 is coming and I’m trying to stay ahead of the curve on this one so I’m moving the NAMOS LAN over to an IPv6 network [public services such as DNS, Web and mail are already running on IPv6] which means in the meantime I’m going to have to go through some of the transitional [...]

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

Just as I’ve finished consolidating all my Physical machines to HyperV guests Microsoft have announced Windows HyperV Server which is a free download.
With the release of the HyperV Linux Componants I’m going to start moving some workloads away from my old ESX 2.5 servers and see if HyperV Synthetic devices work as well as [...]

Recently I encountered a situation where a vanilla install of Postfix had been targeted by what appeared to be a Spam Botnet. Bizarrely this server was what you could call an ‘Edge Server’ but it didn’t have any AntiVirus or AntiSpam to be honest it was pretty useless.
There were three issues to clear up. First [...]

In the previous post on this subject I mentioned that I’ve been working on a little project regarding the EdgeTransport.exe.config file. With the advent of PowerShell I decided to look into writing my own Cmdlets and the EdgeTransport file seemed like a good place to start.
To get started you’ll need to download the Cmdlet from [...]

Whilst there are a lot of features in Exchange 2007 that can be configured and tweaked using the GUI and Powershell I have on several occasions (bare in mind I work in Managed hosting so these occasions are not all for the same installation) needed to ‘play’ with the settings in EdgeTransport.exe.config file [which should [...]
