When you build a KVM guest, if you want to install the guest over the network, you should attach the video console of your guest to a VNC display.
How can I put this..? This is quite a novel way of doing it. I think there’s a reason that more virtualisation systems don’t work in this […]

In between browsing Facebook and Youtube, the UK economy generates $1,930,000,000 of output a year. Thats $550,000 every two and a half hours. Well if today had been a work day, there’d have been one two and a half hour period where that was much higher. That’s because in a pique of […]

Like most original internet standards, the DNS was designed to initially suit the needs of any section of the world that could communicate using 7-bit ASCII and Latin character sets. Then the internet became really popular. Everywhere. The DNS had to evolve to cope with naming schemes that came from alphabets all […]

I presented a talk on recent European Internet exchange news [download] with Mike Hughes from the LINX last week at UKNOF. Many of the attendees run networks that do not peer publicly, so it was a pleasure to explain the impact that European IXPs have on member traffic. We also then gave a […]

Ever since John Gage of Sun first offered the phrase “The Network Is The Computer” to the world, people have been using it as inspiration. Sun use it to explain that they mean Social Networking without actually using the phrase (they prefer the old fashioned “community”).
I think web 2.0 developers are offering a new […]

I come from an IP engineering background, and now work in a telecoms role with Localphone.com. Huge amounts of crossover exist between the two disciplines, especially now that inter-company telecommunications interconnections are now regularly made over IP, but much of what someone will learn about peering in the voice world will not be mellifluous […]

“Ma Bell is a system I want to explore. It’s a beautiful system, you know, but Ma Bell screwed up. It’s terrible because Ma Bell is such a beautiful system, but she screwed up. I learned how she screwed up from a couple of blind kids who wanted me to build a device. A certain […]

I’ve been allowing the webcast of RIPE55 to mutter away in my ears all week and have let myself get distracted from time to time when the topics turned relevant to networks I operate or the chatter got interesting. A bit like the end of today’s ipv6-wg session.

I have been fairly consistently telling people a lie for the last ten years - and that is that Round Robin DNS can not be used for high availability. Its a view I have held pretty strongly, but two people have shown me techniques in the last week that have made me change my […]

For months, ISPs in Europe have been campaigning to preserve their ‘mere conduit’ status, or in English they have been fighting to prove that they should be able to treat all packets, between customers and the resources that they want to access equally. This means, no content blocking, monitoring, and fundamentally no commercial favouritism - […]
