As we enter the year, many, if not most, organizations have already been engaging in 2019 planning and strategizing. With that in mind, we thought what better way to wrap up our first season of Kernel of Truth than with an episode dedicated to trends and predictions straight from the brains of some of Cumulus’ brightest — CTO and Co-founder, JR Rivers, TME manager Pete Lumbis, and consultant David Marshall.

Join as we as discuss EVPN, virtualization, keeping up with the demands of digital transformation and more. This will be our last episode of the season, with our next season kicking off later this month.

Asterisk on Raspberry Pi

RaspPBX is a project which brings the free and open source Asterisk and FreePBX into Raspberry Pi board. RaspPBX turns Pi into a communications server which can be used by small businesses with up to 12 extensions. FreePBX is a web-based open source GUI  that controls and manages Asterisk. Our goal is to show installation of the latest RaspPBX into Raspberry Pi 3 Model B Rev 1.2.

The latest image available for download includes Asterisk 13.20.0 and FreePBX 14.0.2.10.

1. Download, Extract and Copy RaspPBX Image to SD Card

$ wget http://download.raspberry-asterisk.org/raspbx-04-04-2018.zip
$ sudo dd bs=4M if=raspbx-04-04-2018.img of=/dev/mmcblk0 status=progress conv=fsync
$ unzip raspbx-04-04-2018.zip

BGP Implicit and Explicit Withdraw

BGP Implicit and Explicit Withdraw are important BGP messages. Understanding these two mechanisms not only help for understanding BGP convergence but also helps for BGP path diversity.    While I was explaining BGP Add-Path in my Instructor Led CCDE course, I used the term ‘BGP Implicit Withdraw’ Then someone asked what is ‘ BGP Explicit …

Whither Network Engineering? (Part 1)

An article on successful writers who end up driving delivery trucks. My current reading in epistemology for an upcoming PhD seminar. An article on the bifurcation of network engineering skills. Several conversations on various slacks I participate in. What do these things have in common? Just this:

What is to become of network engineering?

While it seems obvious network engineering is changing, it is not so easy to say how it is changing, and how network engineers can survive those changes. To better understand these things, it is good to back up and take in a larger view. A good place to start is to think about how networks are built today.

Networks today are built using an appliance and circuit model. To build a network, an “engineer” (we can argue over the meaning of that word) tries to gauge how much traffic needs to be moved between different points in the business’ geographical space, and then tries to understand the shape of that traffic. Is it layer 2, or layer 3? Which application needs priority over some other application?

Once this set of requirements is drawn up, a long discussion over the right appliances and circuits to purchase to Continue reading

Response: Modchips, Hardware Implants and Bloomberg falsehoods

This video was presented at the 35C3 conference in Germany last week. The presenter is highly credible on the topic. Hardware implants and supply chain attacks have been in the news recently, but how feasible are they and what can we do about them? In this talk we’ll examine the design of a proof of […]

IDG Contributor Network: Did IoT cyberattacks cause NY power transformers to explode?

Officials blamed a power surge for the blackout on Dec. 28th that left LaGuardia airport in the dark for about 45 minutes, grounding flights. A look at the trend of power outages at American airports shows a disturbing pattern and possibly sinister cause.Background Attacking an adversary’s infrastructure is asymmetrical warfare. It causes a lot of damage for a very small cost. Cyberattacks are an ideal weapon as they disguise who might be behind them, making retaliation much harder.  Attacks on the power grid for airports are especially devastating as they ground flights, stranding passengers and disrupting business nationwide. Just take a look at recent power outages:To read this article in full, please click here

How blockchain will transform the IoT

Two giant industrials, Bosch and Volkswagen, are among companies that are taking seriously the idea that the Internet of Things (IoT) and decentralized data marketplaces should co-exist. That means a type of "blockchain meets IoT" is likely in our future.Both German organizations have recently teamed up with fellow-country, decentralized transactional platform IOTA on various development projects. IOTA’s Tangle is a transactional data transfer and settlement system for connected devices.[Also see our corporate guide to addressing IoT security. ] Bosch announced in November that it intends to use a combination of its XDK (Cross Domain development Kit) product (an IoT prototyping and programmable sensor module used as a come-on to get organizations to work with Bosch on custom mass production and series engineering), and morph XDK with IOTA marketplace along a masked communications channel.To read this article in full, please click here

The Week in Internet News: India Pushes for Sites to Remove ‘Unlawful’ Content, Break Encryption

Not this again: India’s government wants websites and social media platforms to remove content regulators determine as “unlawful” within 24 hours and to create automated tools to identify this material, BuzzFeed reports. The government also wants the tech companies to trace the source of the content, requiring platforms like WhatsApp to break encryption. This follows passage of an Australian law that forces online services to provide the government there with encryption workarounds.

The Wire of India defends the proposal, however, saying it’s aimed at holding websites and social media platform more responsible for the content they distribute.

More blocking: The government of Sudan has shut down most Internet access in the country and blocked access to social media platforms, Rogue Media Labs says. The government blamed the shutdown on massive protests over income inequality and other issues.

Missed assignments: In a related story, some college students in the Indian region of Kashmir have missed deadlines for submitting online application forms of their bachelors of education examination because of frequent and lengthy Internet shutdowns there, reports Kashmir Reader. Students are asking the University of Kashmir to extend its deadline.

2019 Is The King of Content

2018 was a year full of excitement and fun. And for me, it was a year full of writing quite a bit. Not only did keep up my writing here for my audience but I also wrote quite a few posts for GestaltIT.com. You can find a list of all the stuff I wrote right here. I took a lot of briefings from up-and-coming companies as well as talking to some other great companies and writing a couple of series about SD-WAN.

It was also a big year for the Gestalt IT Rundown. My co-host with most Rich Stroffolino (@MrAnthropology) and I had a lot of fun looking at news from enterprise IT and some other fun chipset and cryptocurrency news. And I’ve probably burned my last few bridges with Larry Ellison and Mark Zuckerberg to boot. I look forward to recording these episodes every Wednesday and I hope that some of you will join us on the Gestalt IT Facebook page at 12:30 EST as well.

So, what does that leave in store for 2019? Well, since I hate predictions on an industry scale, that means taking a look at what I Continue reading
