Forward Networks has stepped out of the shadows to announce their Network Assurance platform, and I was fortunate enough to be a delegate for Networking Field Day 13 to see their first public briefing. We were all excited to set foot onto the Andressen Horowitz campus that day, but none of us were quite sure […]
Intel Atom SoC bricking more than Cisco products
Looks like the culprit in the recent Cisco debacle is the Intel Atom “System on Chip” (SoC) that Cisco used in it’s gear. My sources within Cisco won’t give up the goods, but many seem to be pointing to Cisco, although a single source at Cisco seemed to indicate there was another player included in […]
Cisco goes public with Clock Signal Component Issue
A couple months ago many engineers started hearing rumors regarding an ISR 4331 recall, and problems surrounding the device. Until this week, none of us had very good information, but it seems that today Cisco has officially released some information regarding the problem. Many of us have received phone calls at this time from our […]
Networking Field Day 13 – Sneak Preview
This is going to be a busy week for the Tech Field Day family. They have delegates en-route to Tech Field Day 12 this morning, and Wednesday the crew for Network Field day 13 arrive. I can’t express how excited I am about going to Networking Field Day 13 this week. I haven’t been to […]
5 important reasons you should learn scripting
Today’s IT landscape if full of software defined marketecture, and lore of a dystopian future full of network engineers that do nothing but write code. But in reality, there are plenty of actual reasons you should be learning programming, or at least some basic scripting. For many network engineers programming is not new, we have […]
The complexity required for robustness, often goes against robustness
In the past few months we have seen major outages from United Airlines, the NYSE, and the Wall Street Journal. With almost 5,000 flights grounded, and NYSE halting trading the cost of failure is high. When bad things happen IT personal everywhere look at increasing fault tolerance by adding redundancy mechanisms or protocols to increase […]
Site Upgrades for September 2015
First, I want to apologize for not doing my job. Over the past couple years I’ve let this site become slightly stagnant. I won’t attempt to make excuses, but I will say that I’m in a much better place now. Hopefully inspiration will continue to strike, and I will continue to put pen to paper… […]
RouterJockey is launching a clothing line?!?!???
Ok maybe that title is a bit grandiose… But due to the great response I received Friday morning from the launch of the original PCAP shirt, and the IPv6 follow-up, I decided to create a few new designs and put everything into a store front. If the demand continues I will continue to publish new […]
PCAP or it didn’t happen…. The t-shirt!
Some days I don’t know why I do things… But last night I was playing around with creating a PCAP meme when my friend Josh Kittle said he’d be interested in a t-shirt like that. I got to thinking about it and realized some network engineers out there also might enjoy something like this, so […]
ASA v9.4 Elliptic Curve Cryptography with TLS1.2
With ASA version 9.4 Cisco has added support for Elliptic curve cryptography (ECC), which is one of the most powerful types of encryption in use today. While ECC has been in use since 2004, only it’s recently use has skyrocketed. Part of this reason is power consumption… In my limited understanding, experts have concluded that […]
