Show 250 – How To Document A Network
A favorite topic among network engineers, documentation is a source of both wonder and horror. Network documentation is difficult to get right. How much detail is enough? How old is that diagram, really? Can't this be automated? Wait, the automated generator spit out *that*? In this show, the Packet Pushers along with former guest Dominik discuss their documentation experiences, good and bad. What have we gotten right? What have we gotten wrong? What's been worth the trouble? What was a waste of time? What did we wish we'd documented before we really needed it?

The six pillars of Next Generation Endpoint Protection
This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach.
Advancements in attack evasion techniques are making new threats extremely difficult to detect. The recent Duqu 2.0 malware, which was used to hack the Iranian nuclear pact discussions, Kaspersky Lab, and an ICS/SCADA hardware vendor, is a prime example. To keep up, a new security model that uses a different approach to the traditional “evidence of compromise” process is needed.

Engineering Lessons, IPv6 Edition
Yes, we really are going to reach a point where the RIRs will run out of IPv4 addresses. As this chart from Geoff’s blog shows —
Why am I thinking about this? Because I ran across a really good article by Geoff Huston over at potaroo about the state of the IPv4 address pool at APNIC. The article is a must read, so stop right here, right click on this link, open it in a new tab, read it, and then come back. I promise this blog isn’t going anyplace while you’re over on Geoff’s site. But my point isn’t to ring the alarm bells on the IPv4 situation. Rather, I’m more interested in how we got here in the first place. Specifically, why has it taken so long for the networking industry to adopt IPv6?
Inertia is a tempting answer, but I’m not certain I buy this as the sole reason for lack of deployment. IPv6 was developed some fifteen years ago; since then we’ve deployed tons of new protocols, tons of new networking gear, and lots of other things. Remember what a cell phone looked like fifteen years ago? In fact, if we’d have started fifteen years ago Continue reading
Worth Reading: Vagrant and Cumulus
Matt has a greater starter up on running Cumulus IX on a Vagrant installation — since Vagrant is available on a few widely deployed machines, this is a great tool for learning the environment. As soon as I can get one of my Ubuntu machines local, or figure out how to get enough drive space on one of my laptops to install this, I’ll be getting Vagrant set up to use on a few different things.

Video: What Is Cumulus Linux All About?
In May 2015 I invited Dinesh Dutt to talk about Cumulus Linux and its typical use cases on an update session of the Data Center Fabrics Architecture webinar.
As expected, he started with the big picture: what is Cumulus Networks and Cumulus Linux all about?
Atom editor – high CPU usage
Just downloaded Atom – a ‘hackable’ editor that has a really slick user interface on the Mac. It’s really nice application, but weighs in at 200MB!
I was doing some work on a few router config files – about 2MB each file – when I noticed the fan spin up on the computer. Looking at the process list, ‘Atom Helper’ and Apple’s spell-check processes were both running very high. There’s not much point in having spell-check on a router config I guess, so I disabled it – problem fixed…
