Setting up Lync SRV Records with Claranet – Office 365

Office 365 is (in a nutshell) a bunch of Microsoft services and software that are (mainly) cloud based.
Some of the important features to trial in Office 365 before we conclude whether it is something we want to go ahead and adopt are the Exchange Online, Sharepoint, Lync and Office Web Apps.

Whilst attempting to trial Microsoft Lync, I came across a few problems trying to add the SRV records to our domain host, Claranet.
A SRV record has many parts to it which I thought were not adequately labelled in Claranet’s control panel. Even after following online examples (Wikipedia has a good one), I was still not able to get it working.

Getting GTranslate to Work with WordPress and HTTPS

I installed GTranslate on my blog (the one you’re reading!) not long ago and noticed a strange problem I was having with settings not being saved and the plug-in not showing up as a widget on the home page when it was activated.
If you have the same problem, you will notice the “Configure it from WP-Admin -> Settings -> GTranslate to see it in action” showing up in your widget bar.

How to Boost your Wireless Strength with DD-WRT

If you have a DD-WRT powered router then you already know how powerful and feature-full it is, compared to a standard out-of-the-box ISP provided router.

This article will be about making use of the features that DD-WRT provides out of the box, as well as some other ‘hacks’ we can use to boost the wireless signal in your home or office.
The ones I will talk about today are as follows (in order of usefulness and ease):

  1. Wireless channel selection
  2. Update firmware and/or drivers!
  3. Transmit (Tx) Power
  4. Beacon Interval

Force DD-WRT to use OpenDNS Servers for DNS Queries

In one of my recent articles, I explained how I set-up a guest wireless network for our work place (after getting it to work with the right wireless channel :))

After configuring the guest access point, I set up the DNS servers to point to OpenDNS in order to provide a safer and faster DNS service (compared to the default DNS servers our ISP provides) as well as choosing what web-sites should be allowed on the network.
For example, bandwidth hogging (Media/Video Sharing) and other web-sites which could potentially be used for illicit purposes (P2P/File Sharing) are forbidden on the network.

However, without any firewall rules on the router itself, it would still be possible for a guest on the network to change their DNS settings on their wireless adapter to point to any other DNS server; effectively bypassing all OpenDNS filters on the network for that specific client.

Using DD-WRT and DNS-O-Matic to Automatically Update DynDNS, OpenDNS and Other Services

DNS-O-Matic is a free service provided by OpenDNS. With DNS-O-Matic, you can propagate IP address changes across multiple services such as DynDNS, OpenDNS and many others.

With DD-WRT, you can set-up DNS-O-Matic so that your services stay updated with your IP changes as soon as they happen.

This article will very quickly go through the process of setting DNS-O-Matic on your DD-WRT powered router.
