NAMOS LAN Native IPv6 - Complete

November 3rd, 2008 by Gareth Llewellyn

With the initial tests over it was time to actually move over to ‘real’ IPv6 addresses.

October 15th, 2008 by Gareth Llewellyn

We already know that disabling IPv6 on a 2008 & Exchange 2007 server breaks things but what if we go IPv6 only?

October 11th, 2008 by Gareth Llewellyn

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 [...]

May 18th, 2007 by Gareth Llewellyn

This months updates have meant that a lot of my servers now have outdated packages. Bandwidth isn’t really too much of problem when it comes to my RHEL servers as they sit on 100mbit connections in Telehouse and Texas, however all my home and office based CentOS servers sit on a mixture of 2Mbit [...]

Free WiFi and What People Do With It

May 10th, 2007 by Gareth Llewellyn

Anyone travelling through Reading may have at some point seen the unsecured wireless network called NAMOS. Well thats me.
The Network isn’t totally insecure, the Access Points sit behind a Juniper NS5GT and all web / IM / mail is piped through a BlueCoat Security Appliance. I noticed that the client stats were increasing and I [...]
