Got a Question? Contact Me!

December 9, 2012

I have added a contact form to the website to make it easier for people to get in contact with me about things on my blog.

This is to try and stave off the increasing labyrinth of comments that appear to be increasing across my site with questions about the scripts, that are not necessarily related to the blog post itself. Because of this new feature, I will no longer publish comments that are:

a) Not directly related to the post
b) comments to posts older than 2 months.

However, if the questions/comments received are non-trival, I will now include regular Q&A Blog posts to cover the question :)

Thanks for reading :)

Going Mobile with HP

August 11, 2014

Well, I am back in HP space for a little bit – configuring up a couple of HP c7000 chassis with some Gen8 blades. Being Gen8 they come equipped with an iLO4 interface and it has given me the opportunity to use the HP iLO mobile app. For the purposes of this article, this app was being used on an iPad Air with a bluetooth keyboard.

Having got my basic configuration into the blades I started adding them to the app, which was a little tedius having to re-enter the same credentials all the time. Dear HP, I would love a setting to be able to have a default or global credential store.

This can be worked around however, particularly if you are familiar with QR Codes. Making some assumptions that your server room is secure, you can print out QR codes for your devices with a string of hostname;username;password to put on servers, and then adding servers becomes a scan of the QR code using the app (or a paper based booklet of ‘codes’). The big problem here is that if you do not keep these QR codes secure, anyone with a QR code reading app can obtain login credentials.

As seen in the first image, I have a list of iLO interfaces. There are a couple of servers there with detailed information, and that is collected once you connect to the device for the first time. There is very limited organisation of the devices, with the ability to have a favourites list and thats about it. Dear HP, I would really like to see the ability to see folder organisation in future releases of this app. This will become unweildy with lots of devices.

Are Some of your GTalk Contacts Offline since using Hangouts? This Might be Why.

July 15, 2014

This article is slightly different from my usual articles, as it’s more about the use of a chat client. However this issue has been one that has been causing me great pain and frustration, and having found the root cause of the issue has been quite a relief. I figured I would share in case others were experiencing.

Over the last 3 months, a group of friends and I have been using Google Hangouts as the primary medium for messaging. Due to the use of an XMPP Bridge, we are able to use chat clients like Digsby, Adium and Pidgin. This worked great, until one day I noticed one of my friends did not appear online any more, though I would receive messages from him. Attempts to remove and re-add the contact, as well as completely & mutually removing our Google Plus and Gmail Contact info from each other did not resolve the issue.

After 3 months, the issue and resolution was finally found on the Google Product Forums. It would appear that when you disable sound notifications in google hangouts for messages, unexpected behaviour can occur including that you will appear invisible to other chat clients. My friend verified this by un-muting notifications, and *boom* he appeared online in a variety of clients we were testing.

So there you have it, if you are having trouble with friends who use Hangouts appearing offline in your chat clients, see if they have muted/disabled message notifications.

Microsoft Release TMG 2010 SP2 Rollup 5

Upgrading VMware ESXi with NetApp NFS Storage May Cause VMs to Stop Responding

April 2, 2014

It was supposed to be a routine ESXi upgrade. Having discovered that one of the NetApp's OnTap software had a memory leak which was causing a controller to slow down and eventually fail over every 3-6 months, a pre-requisite of updating the OnTap software was to upgrade the ESXi hosts to at least version 5.

Having been doing a number of these upgrades recently, my confidence was high as I submitted the change requests, notified stakeholders and completed the upgrade.

And then the phone calls started.

IPv6 Roadshow Wrap

March 11, 2014

Last week I attended the SAGE-AU IPv6 Roadshow that was sponsored by Megaport.

I attended the Hobart event and for someone who has has little to do with IPv6, this event was an excellent introduction. Some of the things I found worthwhile form the event included:

  • How an IPv6 Address is put together and notation rules.
  • Reserved address spaces for IPv6
  • Subnetting a prefix
  • Changes made in the Packet Header compared to IPv4
  • Auto-configuration and Discovery Protocols

There was a lot of in depth information available for those who attended. I think everyone who attended was pleased with the outcomes of the event and hope that SAGE-AU continues to hold more training events like this in the future.

SAGE-AU IPv6 Roadshow

February 18, 2014

IPv6 Roadshow Logo

Have you heard about SAGE-AU‘s National IPv6 Roadshow coming up in March?

SAGE-AU is running a 1 day event around capital cities in Australia to provide IT Professionals an introduction to the new address scheme of the internet and how you would go about implementing IPv6 in your home/business/organisation.

I think many people believe that IPv6 is still a fair way off, and with google reporting some 3% of traffic to it’s site as IPv6, perhaps it is. The problem for those people though is that take-up is accelerating as more networking devices become IPv6 compatible and I think in the next 2-3 years, people will suddenly need to know about IPv6.

To me, it makes perfect sense to get a fundamental knowledge of IPv6 now and be ahead of the game when the protocol hits critical mass.

The IPv6 Roadshow is coming up soon, so if you are thinking about coming, you should register now!

Also, as an IT Professional, you should probably join SAGE-AU and make use of their great benefits.
