Finding a New Path (Part 1)
In my last installment on the topic of fast convergence, I said I’d be discussing the calculation stage of fast convergence next. Orhan tried to scoop me in the comments, but that’s okay –I’m working at this through the process switched path, rather than interrupt context. In parallel with flooding information about the topology change […]

Professional Loneliness
Lately I’ve been bouncing some generic DMVPN questions off the twittersphere. I’ve used DMVPN sporadically in tiny single-use cases before, but now I am planning to roll out a somewhat larger implementation with a dual cloud and dual hub, complicated by the fact that I don’t control the perimeter router at our DC and I […]

The Priorities Bill of Rights – 10 practical steps to managing group priorities
Managers everywhere are abusing their employees by using priorities to convey to-do lists. It is not because of anything insidious in their objectives, but the average manager (both low- and high-level, by the way) simply doesn’t think enough about priorities to really do anything meaningful with them. For teams I lead, our entire existence revolves […]

Forum Going Away – But New Things Are Coming
Roughly a year ago, we built forum.packetpushers.net. This was a forum site built on vBulletin. The idea was to give the community another place to exchange ideas, share information, and help each other with challenges. After considering the matter for a couple of months, Greg and I are going to shut the site down. For […]

IT’s Not Just About Technology
There’s a lot of great blogs and resources that get really deep into specific areas of tech. While it may sound really strange, this site is decidedly not one of them. The focus of The Tech Interview is quite different. Instead of focusing on the bits and bytes of technology, we look at the un-tech […]

Automation : Not Just Marketing Fluff
Regardless of where you stand on the future of data networks and SDN and the prevailing idea that dust made from ground up rainbows will be powering our pipes – there is something that I believe is being overlooked and should definitely be addressed.

More Snowden Media Douchebaggery
I previously wrote a post in response to an article that equated Snowden’s CEH certification to James Bond’s “license to kill.” Well, it looks like some technically-challenged media types are at it again. They’ve called Snowden “brilliant” for his ability to “impersonate” users on various systems in order to obtain certain documents and I felt […]

Turning BIND DNS Management Into A Walk In The Park
DNS needs no introduction in today’s inter-networked, connected world.

Why ‘your’ project was outsourced
It’s easy to get upset when that cool new project you wanted is outsourced to an external VAR. The conversation usually goes something like, “You know the existing network and services really well so we’re going keep focused there.

Balancing Complexity and Simplicity
I’ve been in tech for several years. Over time, I’ve configured things that I’m proud of and I’ve built things that I’m not so proud of. Most of the things that I’m less proud of involve unnecessary or unwarranted complexity that has created operational challenges. In some cases this was a result of a small […]
