My Network Toolkit
A while back, Chris Marget of Fragmentation Needed posted a run-down of his comprehensive and extremely clever network toolkit. Because I'm something of a weight weenie, mine is a lot more slimmed down. I thought I'd post it here:
The contents:
- Two random USB drives (in case I need to leave one with somebody).
- Single-mode and multi-mode LC fiber loopback plugs.
- Rack PDU plug adapter.
- Awesome PicQuic compact screwdriver (thanks to Chris's post).
- T1 loopback plug (red) (because we still have T1s out here in the boonies).
- Cat-6 pass-through plug (white).
- Crossover adapter (orange).
- Sharpie.
- Console setup:
- USB-to-DB9 adapter.
- DB9-to-RJ45 adapter.
- Flat Cat-6 cable.
- Rollover adapter.
- Velcro tie
- Flat Cat-6 cable with velcro tie.
The Fenix AA light and Leatherman Skeletool CX almost always live in a pocket rather than the kit and go with me everywhere. The kit all fits into a small zippered case that used to hold a Dell laptop power supply.
My main goal here was to have all the hard-to-find professional stuff in Continue reading

Friday News Analysis: “Size Matters” Tech Podcast for SMB’s Launching
I noticed a tweet about a new tech podcast that will be starting soon focused on the SMB space. I used to consult for SMBs, and I know the needs to be unique. SMBs often have many of the same technical needs of large organizations, but lack the scale requirements. Technology purchases are expensive, and business […]Using the Junos Space REST API
Automation is going to be fundamental in all networking products. I’ve been working a lot on integrating Juniper products in existing and standard software. There are many different ways to automate something on a network running Junos. Using REST (or RESTful) APIs is one way of doing this. The reason I’m using REST is that it’s fairly easy to understand, but the best thing is that a large amount of existing products supports REST to integrate with it.
The goal of this blog is to explain how Junos products support REST, compatibility with older versions and how it scales.
What is REST?
REST (REpresentational State Transfer) is a simple stateless architecture that generally runs over HTTP. There are 4 commonly supported commands. When you issue a command your input data consists of a URL, HTTP headers and a body holding the data.
HTTP Headers are used for things like Authentication and a Content Type to let the application know what data format the body will contain.
The URL specifies which data you want to receive from the application or you want to change.
The body is empty in a request for data, when you want to change some data this Continue reading
Networking FAQ 1: Breaking into the Field
This post is the first in a series I plan to publish over the next few months regarding frequently asked questions in networking. Each post will cover a different subject, roughly following the outline I shared last summer. I hope people find this useful!
- What kind of networking jobs are there?
- What are the different networking specialties?
- How do I get into networking?
- Do I need a college degree to be a networker?
- Do I need certifications?
- Do I need to know a programming language?
- What should I list on my resume?
- How much do networkers make?
- How do I find a job?
- Do you have any interview tips?
- What are the negative aspects of networking?
The Most Important Skill to learn for 2015
Original content from Roger's CCIE Blog Tracking the journey towards getting the ultimate Cisco Certification. The Routing & Switching Lab Exam
In this ever advancing world of technology there has never been a better time to be able to get things done anywhere, but there has also never been so many distractions stopping you getting things done. With the constant connectivity to the internet, facebook, twitter, etc etc we are now absorbing more information every hour... [Read More]

A Bright And Happy 2015 Ahead
Welcome to a new year finally divisible by five! This is a year devoid of extra February days, Olympics, or anything else. It’s a chance for us to take a look at technology and make things better and easier for users and IT staff. It’s also probably going to be called the year of VDI, NFV, and SDN. Again.
Rather than writing a wrap up post for the end of 2014 like so many other sites, I like to look at what I said I was going to do 365 days ago and see if I followed through on them. It’s a way to keep myself honest and also to see how the year transformed around me and my goals.
Looking at 2014
Thankfully, my goals for 2014 were modest. I wanted to get more involved with the people in the IT industry. And I did that in a big way. I went to a ton of conferences and events through the year. Cisco Live, VMworld, and HP Discover Barcelona were all on my list this year, as well as all of the Tech Field Day events I took part in as an organizer. It was a grand Continue reading
Docker Networking – Part2
This blog is part of my Docker series. This is a continuation from my previous blog on Docker Networking. In this blog, I will cover current Docker networking limitations, Pipework overview and a sample Docker application where I have linked containers in 2 different hosts. There are 4 networking options that Docker provides when creating … Continue reading Docker Networking – Part2
Using IPv6 to Defeat Multi-tenancy Separation
I’ve always advised my clients to carefully plan the implementation of IPv6. The protocol opens new attack vectors on which ne’er-do-wells can assault your infrastructure. There are countless examples I’ve seen such as service providers locking down access to routers using IPv4 transport but leaving IPv6 transport completely open. About a year ago, I stumbled […]

Community Show – The Rash Came Back After 19 Hours

CloudFlare in 2014: Bigger, Faster, Securer
At the end of 2013 we posted a blog article titled 2013: Rebuild the Engine; 2014: Step on the Gas which explained how in 2013 we had been rebuilding the engine that powers CloudFlare and how we expected 2014 to be when we stepped on the gas.
In that blog post, we said that we'd be expanding our network to betters serve customers in China and Latin America (as well as continuing other global expansions), and that we'd be making a big announcement around SSL.

Looking back at 2014, we did a whole lot more and many of those changes had a meaningful impact well beyond CloudFlare. Now when we make a change, the needles on the Internet's dials move: when we roll out support for new protocols, sites tracking those protocols see a sudden jump in usage.
Here's a month by month review of CloudFlare's 2014:
January 8: keeping our promise to Latin America, we opened our first data center there in Chile.
January 27: we published our first transparency report covering National Security Orders on the first day it became legal to discuss them.
February 13: we Continue reading
Junos PyEZ Installation & Initial Testing on Mac OS X
I am educating myself about network automation. As I spend a lot of time in the Juniper world, a natural place to work on automation skills is by leveraging PyEZ. What is PyEZ? Juniper describes it this way in their techwiki. Junos PyEZ is a microframework for Python that enables you to remotely […]My Review of 2014. Who Cares ?
I started to think about what happened in 2014 and decide which events changed networking.

Whoa… What’s with this Ad in the software (hint: it’s not an ad)
Those who are trying out the new gns3 software may see something that is not like the old software. Do you see it? Its not ASA -2014 Recap and 2015 Goals
When I started this post, the following mental image popped into my head, and I found it an apt description of 2014:

Oh well…..let’s give this a try anyways.
2014 Recap
I’ll list off the goals I set in my post one year ago, and reflect upon how they were pursued in 2014:
Write Code – I knew when I made this goal that it was going to be hard to quantify; I just knew that writing code was something I had been passionate about. Though I have always maintained this skillset in some form or another, I knew I wanted more, and a year ago, I made the goal of increasing my involvement with software development.
In 2014 I made two more contributions to OpenDaylight, specifically pertaining to the Unit Testing and Integration Testing efforts of the OVSDB project (much thanks to Madhu Venugopal and Dave Tucker for their unrelenting patience while I stumbled through Junit fundamentals). I also did a lot of work on various projects, like Ansible and Schprokits extensions, as well as standalone projects, all of which are Continue reading
