You might have noticed that I’ve not updated this for a while – that’s because I’ve moved, and not just my blog!

There might be the occaisional update here, but most will be over at the new blog.

On the move

This is a test post using the Wordpress client for my iPod Touch. It’ll take a bit of getting used to before I can do links and formating!

Belkin OmniView Soho Series KVM Review.

Saturday, August 18th, 2007

I have used a Belkin OmniView KVM for years to switch between my three main computers – a Centos server, a Fedora workstation, and a Windows Vista workstation. My old KVM used PS/2 connectors for the keyboard and mouse, and only supported a single monitor shared between the computers. When I upgraded the hardware that is my Fedora workstation I got a USB keyboard and mouse, in addition both of my workstations now have dual head graphics cards, so I decided to look about for a new KVM.

My requirements were:

  • Support a USB keyboard and mouse
  • Support dual heads (two monitors)
  • Support at least 1280 by 1024 resolution on each monitor
  • Support at least four computers

After a bit of research I settled on the Belkin Omniview Soho Series 4-Port Dual Head KVM Switch. I ordered the switch from Amazon UK and sat back to await its arrival. The KVM arrived and I realised my first mistake – I had naively expected that it would use generic USB and VGA cables, but no you needed to purchase the special Belkin Cables. Back on to Amazons website and I had ordered three cables, unfortunately due to a Postal strike the delivery was delayed for almost a week.

Once the cables had arrived I powered down my machines, removed the old KVM and cables, and then installed the new system. Once the cabling was complete I powered everything back on and hit a problem. When I logged into my Centos server I noticed a problem with the IMAP service starting so I tried to run some commands to debug the issue, this involved typing the | character, but I couldn’t type this character on my new USB keyboard. My first reaction was that this was a Centos problem, possibly it was failing to properly recognise and configure my USB keyboard, so I logged into Windows Vista to see if that exhibited the same problem. It did.

Looking at Belkins support website I discovered that there was a firmware update available for the KVM which claimed to fix the problems with the missing key support (\ and # being the main ones). I downloaded the firmware and the installer application. From reading the release notes I noticed that it didn’t support Linux (no surprise) nor Vista, so I copied the firmware and installer my laptop running Windows XP. I installed the installer, rebooted, and then tried to update the firmware. Problem number two, the update always failed. Ah, I had seen this mentioned in the release note, the solution was to power off the KVM, unplug the cables, and the reconnect them. So I did this and it failed. So I did it again, and it failed again. Five of six times I repeated these steps, even rebooting my laptop a couple of times as well, still it failed.

Next step, call Belkins UK Customer Support number, it’s an 0845 number, 10 pence per minute cost to me, profits shared between Belkin and the Telco! The engineer I spoke with immediately acknowledged the problem, and even admitted that the only reliable way to get the upgrade to work was to use a Windows 98 or Windows ME system. Given that these systems are years old and no longer supported by Microsoft where was I going to get such a system. The Belkin Engineer had obviously come across this before and suggested that I send the KVM to him and he would flash it using one of the Windows 98 systems they kept specially for this purpose!

So I boxed the KVM up and sent it off. A week later it returned and again I powered down all my computers and reinstalled all the cabling. Powering the computers up I could login and use the previously missing keys.

So would I recommend the Belkin Omniview Soho Series 4-Port Dual Head KVM Switch, probably not. There are two issues that hold this device back: firstly it doesn’t have great support for USB keyboards, having to update the firmware to get the | and # keys working wasn’t good, and even after this the multimedia keys still don’t work. Secondly the fact the the KVM is sold as having firmware that you can upgrade, but the reallity is that unless you run a computer museum with Windows 98 or ME you won’t be able to upgrade. the only reason to buy this KVM is if you are desperate for the dual head functionality, otherwise look around for a KVM with better multimedia keyboard support.

Nearing completion

Today I installed and configured a version control system – Subversion. The neatest thing I discovered was the ability to apply XSL and CSS stylesheets to the page output when accessing the repository through a web browser. You can check out the effect in the test repository. I also finished uploading the best of my collection of hill walking photos:

Plans for the next few days include:

  • Enable server side includes to make maintaining the navigation side bar simpler.
  • Create a page to manage the different subversion repositories.
  • Tinker with my previous backup script so that we are more comprehensive in our backups.
  • And finally the big one – create a theme for the Wiki to integrate it into the site properly.

Oh, and I have some day job and real life things to be getting on with as well…

Is a photograph better than being there?

I meant to go hill walking today but I when the alarm went off at 6:00am I decided I just couldn’t face it. I’ve not been sleeping to well due to back ache and I think that put me off. Instead I’ve been working on the photo gallery part of the site. Gallery2 is now installed and configured and I have created a custom theme to match the rest of the site. The theme still needs some work get captions, titles, etc, working just as I would like them.

I’ve upload four albums to start with, mostly of different hill walks. I’ll add more albums over the coming weeks.

More progress on the site

I liked the default WordPress theme so I’ve been trying to use it on all the pages and applications that make up this site.  The only drawback was that the default width was to narrow for things like galleries of photographs.  By modifying the CSS and the three images that are used in the theme I’ve increased the page width slightly (100 pixels).  I’ve applied the same changes to the other places I’m using the theme.

The other update today is the addition of feed aggregator using the Planet software.  I am aggregating the various blogs and news feeds that I read on a daily, mainly for convenience.  You’ll notice that this new service is using the modified WordPress theme.

Instant Messaging Using XMPP

Tuesday, July 3rd, 2007

I’m still enthused, so you get another entry!

Progress today involved installing and configuring an XMPP server.  I chose the Openfire XMPP server which is written in Java and released under the GPL licence.  Installation was simple, I downloaded the RPM and installed it, configuration was almost as simple – I pointed a web browser at the management console and followed the instructions.

All this means that you can contact me using XMPP at kms@passback.org.uk.

And so it begins, I get sucked into the world of Web 2.0, user created content, and mash-ups.

I am not a great diarist, so updates will be few and far between, especially once the novelty value wears off. I plan on using this blog to publish updates about changes to the Passback website.
