Speaker for the Dead – Telnet
The idea of this article series is for me to play the part of a ‘Speaker for the Dead’ for technology that has or is becoming ‘end of life’ or legacy and/or irrelevant (or which should be). In this article, I’ll cover Telnet; the good, the bad, the ugly, the full (but brief) and honest […]

Speaker for the Dead – Spanning Tree Protocol
A friend of mine* text me early last week asking if I wanted to go to the cinema and watch the film After Earth. I couldn’t/wouldn’t go as I’m still up to my neck in book writing, but I thought I’d distract myself for a minute or two and read a few reviews of the […]

Networking Learning Paths – Route/Switch or Speciality Knowledge?
I spent the first ten years of my career in mobile telecoms. I learned a ton of lessons and I really enjoyed it, but I’ve always been drawn to networking. However I wasn’t getting hands-on exposure to data networks in my telco job so I had to teach myself. In 2002 I began the transition […]

How do I Justify this?

How can I tell the whole truth, cover all the bases, explain all the alternatives, while making certain I make the case that the technology I’ve made, or would like to make, is the right one?” In case you’ve ever wondered what it’s […]

Have Respect For The Work You Do
The other day I was called in to assist with issue that had been open for a few days.

Are Forensics Tools the New IDS?
For the past few years, many people have been suggesting that the days of IDS (intrusion detection system) are numbered. When IDS was first launched, it was seen as an answer to a lot of network security problems: deep packet inspection with constant monitoring and alerts. However, one of the biggest problems with IDS is […]

Monitoring VRFs on IOS-XR
Lately I have been investigating how to monitor BGP peering session via SNMP instead of traps/syslog messages and I found out that this feature is not documented properly for IOS XR. Finally I managed to get it working, so I thought that it would be worth sharing with the community. In our example, we have […]

Consider an International Relocation
Over three years ago I saw an opportunity to take an assignment to my company HQ in Seattle. After debating this for some time with my wife we took the plunge and moved to the US. The question is, “was it worth it?”. For me the answer is an overwhelming ‘yes’. I’m moving back to […]

Thinking About SDN Packet Processing: You’re the One Talking to a Fish
Barbie films (yes, I really am talking about Barbie in a network blog post) are a big hit with my kids, and surprisingly with me too. I’ll possibly regret telling the world that, but anyway, there’s an exchange in one film* that always make me laugh. It goes like this. Human (Australian accent): “You’re bonkers!” […]

The Attributes of a Great CLI
So, there I was, innocently browsing the OpenDaylight wiki after listening to Show 148 – Talking With OpenDaylight Leadership when I came across the OpenDaylight Command Line Interface page. I’ve not gone through the entire 118 pages (if I were to print it) worth of content, but I’ve scanned through a fair chunk and read the CLI Concepts section in […]

Fun With Unmanaged Switches + Port Security
I’ve just passed a year of my job working at a smallish non-profit, and one part that I really am enjoying is passing on knowledge to the front-line staff. This week, there was an interesting case, and I had to explain to my colleagues what was happening and why. So, I did a little demo, and […]
