This episode of Network Break looks at ONIE security risks, a sensible car hack lawsuit, missing millions at Ubiquiti, EMC and VMware going all the way, a potential Apple win at IBM, and other tech news.

It’s that time of year again—time for VMworld! And along with VMworld comes another highly-anticipated event: Spousetivities! That’s right, Spousetivities is back again this year for another set of outstanding activities organized for spouses traveling with conference attendees. If your spouse is traveling with you to San Francisco for VMworld, this is a great opportunity for him (or her) to meet up with other spouses and attend some exclusive activities.
So what’s on tap for Spousetivities this year? Here’s a quick look at some of what’s planned:
Hey, it's HighScalability time:

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
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.

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?
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…

About 6 months ago, I wrote a post titled Programmatic Access to CLI Devices with TextFSM that talked about what was possible with TextFSM and even some things that could be possible with Ansible.
The overall feedback about the Ansible module (aka netget) shown in that post was great — it was ultimately taking input parameters such as the template file along with the CLI command to execute on the devices in order to return structured JSON data back using Ansible. In other words, the module used Ansible and TextFSM to create a pseudo-API for accessing data in traditional (no API support) devices.
Since then, we have been using TextFSM for a few customer projects and found out there was another capability within TextFSM to create what’s called an “index” or a mapping between CLI commands, vendors, and TextFSM templates. By integrating this functionality, instead of users needing to know what template to call, they can simply just send in the show command, while the index maps the command to the proper template! Pretty sweet!
Needless to say, the Ansible module is officially online and is now called ntc_show_command.
With the right amount of community support, it shouldn’t be Continue reading
Last year, a group of believers gathered for a brief time of prayer while at VMworld 2014. This year, I’d like to again offer believers attending VMworld 2015 the same opportunity to gather together for a time of prayer before starting the day. If you’re interested in attending, here are the details.
What: A brief time of prayer
Where: Yerba Buena Gardens, behind Moscone North (by the waterfall)
When: Monday 8/31 through Wednesday 9/2 at 7:45am (this should give everyone enough time to grab breakfast before the keynotes start at 9am)
Who: All courteous attendees are welcome, but please note that this will be a distinctly Christian-focused and Christ-centric activity. (I encourage believers of other faiths/religions to organize equivalent activities.)
Why: To spend a few minutes in prayer over the day, the conference, and the attendees
Like last year, there’s no need to RSVP or let me know that you’ll be there, although you’re welcome to do so if you’d like. There’s also no need to bring anything except an open heart and a willingness to display your faith in front of others. This is a very casual gathering of believers—we’ll gather together, share some prayer requests and needs, Continue reading
The gold standard for corporate networks today is MPLS, but carrier pricing issues and MPLS’s failure to play well with new, cost-efficient forms of network access are causing problems for the legion of enterprise customers that rely on it.
Consider:
It’s not clear how fast MPLS will go the way of Frame Relay and ATM, but changing apps and bandwidth needs, coupled with Continue reading
