Build a Career with Relationships
Your job hunt traditionally starts with websites like monster.com or dice.com. However, some surveys suggest that between 70 to 80 percent of jobs are found through personal contacts and relationships. So why not spend your efforts building your relationships instead of surfing jobs sites? I can sense some of you getting uncomfortable already. Dont worry, […]

Review: ScienceLogic – One Network Management Tool To Rule Them All?
ScienceLogic has been getting the right kind of press recently – e.g. they were a winner of Best of Interop 2013 – Management & Monitoring, and Infoworld had some rather nice things to say. They’ve got some high-profile customers too, such as Fasthosts and Equinix. But what exactly is their product all about, and is it any […]

Mrs. Y’s Rules for Security Bloggers
Recently Greg Ferro published an e-book for bloggers, “Arse First Method of Technical Blogging.” It has some great suggestions (although I’m not sure what an arse is), but after reading it, I realized it really doesn’t apply to security blogging. Without further ado, here are some of my tips for good infosec blog posts. 1. […]

SDN: Savior or Grifter?
Grift’s like anything else, Roy. You don’t stand still. You either go up or down. Usually down, sooner or later. Lilly Dillon from “The Grifters” At Interop this month, every vendor had product sheets that claimed, “Now with SDN!” It’s the latest industry buzzword and I started to recall some previous one-hit wonders from the past. Remember […]

Programming 101 for Network Engineers – Basic Language Elements & Concepts 1
Welcome to the third part of the Programming 101 for Network Engineers series. This is likely to be the most ‘straight up’ piece so far; all fact and almost no fun (but learning is right?). Sorry, but for now the comment and opinion need to be put aside as we get into some nitty-gritty. The following […]

Two Hours, Two Days…
It’s either two hours, two days, two weeks… or too long. Two things these last two weeks have brought this old saying to mind in full force. First, there is this interesting article about the woes of the Medicaid Management System in Tennessee. Here we have a program that has overrun it’s budget for multiple […]

The Important Question for a Technology Fresher
After spending a considerable amount of time on forums like the Cisco Learning Network, it is apparent that there are many challenges for those entering the field of technology. Freshers, as they are known in the industry, have many challenges. Some of these challenges stem from the gap between the education process and the real […]

Shopping at the SDN App Store: What Enterprises Really Want?
I contributed 2 pieces to a Network World “digital spotlight” on software defined networking (SDN). SDN’s all the rage with marketing teams & the industry media. I’ve been contracted to write or contribute to a total of 3 large SDN pieces, including this one, over the next few months. And of course at Interop, you couldn’t walk […]

Cisco OTV Implementation & Troubleshooting (Legacy Multicast mode)
For the details on what Overlay Transport Virtualization (OTV) is and how it works on a high-level, see my previous blog entry about OTV 101. OTV troubleshooting requires a basic understanding of Multicast, as well as ISIS. In-depth troubleshooting on these subjects are not part of the scope of this document. This document will only […]

Show 147 – Avaya Fabric Connect Makes Multicast Simple (Really) – Sponsored
For many network engineers, IP multicast routing is evil. Difficult to design, complicated to implement, painful to troubleshoot and challenging to scale, multicast routing is rarely implemented on a given network unless it’s absolutely required. Most engineers would just rather not bother until the issue is forced upon them. Blame PIM. Blame RPF checks. Blame […]

Cisco OTV 101 (Legacy Multicast Mode): MAC Learning Process Walk
What is OTV? Overlay Transport Virtualization (OTV) is a Cisco-proprietary protocol suite that allows us to extend Layer 2 between datacenters with Layer 3 boundaries in between. It works by encapsulating the L2 packets into L3 multicast packets and sending them out to all other OTV AED’s (Authoritative Edge Devices, used for loop prevention). The […]

Interop: Firewalls, Booth Babes and Unicorn Poop
Now that I’ve returned from the whirlwind that was Interop Las Vegas, I thought I’d share some thoughts about my experience as a speaker and attendee. First the good: The UBM staff was awesome and I appreciated the chance to pontificate on one of my favorite subjects, firewalls. Thanks to some quick thinking by the […]

Identifying Introverted Tendencies
It’s no secret that our industry is full of those with interesting eccentricities. These characteristics are found in varying degrees with those we come into contact with daily. The extremes of these often manifest themselves as a general perception of those in technology. This even happens as technical characters are portrayed television. One example of this […]

Book Review: A Primer of Multicast Routing
I was recently in need of a refresher on multicast routing, so I picked up Eric Rosenberg’s A Primer of Multicast Routing (Springer Briefs in Computer Science). The overall plan of the book is excellent, starting with a basic overview of what multicast is (and does), including why multicast is more efficient than unicast for […]

How to Turn Your IOS Router Into a Pr0n Server (Pr0n Not Included)
No, really! Did you know that your IOS-based router is capable as acting as a static webserver? Below you will find the steps necessary to turn a GNS/Dynamips box (or any ‘testlab’ machine) into something that can serve basic HTTP/HTTPS content. Due to the security implications of the steps below, it’s not recommended to do […]

Getting the Most Out of SPAN or Mirror Ports
In my previous blog post I looked at the benefits and limitations of SPAN ports. SPAN or mirror ports are a convenient way of getting access to network packets without having to be inline like a firewall. Once you have got your network packet source in place, the next question is, what applications are available […]

Are You a Fuddy Duddy?
This recent article from IEEE Spectrum discusses our impression that as we age, we lose the ability to learn quickly — fluid intelligence, as it’s called. An accompanying chart shows this in some degree through the skill of chess players across a range of ages. There’s something suspicious about this chart, though, and it’s pairing […]

Machine Fragile: More Thoughts
I just ran across a pointer to this research on Bruce Schneier’s blog: Networking system components that are well-behaved in separation may create counter-intuitive emergent system behaviors, which are not well-behaved at all. For example, cooperative behavior might unexpectedly break down as the connectivity of interaction partners grows. “Applying this to the global network of […]
