Companies are Systems for Making Money We’ve all heard corporate leadership speak about ‘human resources’ and that ‘people are our most important asset’. This is true but the words ‘resource’ and ‘asset’ were carefully chosen. A resource is something to be mined for value. Please don’t be fooled into thinking that your company cares […]

The Packet Pushers are joined by Brent Salisbury of networkstatic.net for a chat with some of the top brass on the OpenDaylight project’s Technical Steering Committee, Dave Meyer and Inder Gopal. “What’s OpenDaylight?” you ask. Why, it’s a consortium of vendors working together under the Linux Foundation umbrella to make an open source reference framework […]

At work, we’ve been getting ready to deploy a few different cluster technologies. One is a set of KVM hosts to offer VMaaS functionality to end users. Another is a CEPH cluster (http://ceph.com/) which is smart distributed storage. The third is a Hadoop cluster. Each of these initiatives popped up around the same time and […]

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, […]

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 […]

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. […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

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.

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 […]

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 […]

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 […]
