The Linux Migration: Final Linux Distro Selection

In my Linux migration initial progress report, I provided an early assessment of the Linux distribution that I thought I would use moving forward. At that time, I had selected Ubuntu. Since that time, though, I’ve pivoted a bit and selected a different Linux distribution as the operating system (OS) for my primary laptop moving forward. In this post, I’d like to describe why I selected Fedora.

My original reasons for selecting Ubuntu 16.04 were as follows:

  • Hardware support
  • Performance
  • Leading but not bleeding edge
  • User interface

These are all valid reasons, but as I continued to compare Ubuntu against Fedora 25 I realized that some of these factors weren’t as critical as I’d originally thought:

  • Hardware support: I initially targeted Ubuntu because it runs really well on Apple hardware. Fedora, on the other hand, doesn’t run quite as well on Apple hardware. Since I’m coming from the OS X world, I initially placed some emphasis on support for Apple hardware. The reality is, though, that I need a Linux distribution that does a great job of supporting my new work laptop, not one of my leftover Mac laptops. My experience with Fedora 25 on the Dell E7370 Continue reading

How to make PC security alerts better? Make them twirl, jiggle

Have you ever ignored a security alert on your PC? You’re not the only one.The warnings are designed to save us from malware infections and hacking risks, but often times we’ll neglect them. It could be because we’re too busy or we’ve seen them too many times, and we've become conditioned to dismiss them -- even the most serious ones, according to Anthony Vance, a professor at Brigham Young University.Vance has been studying the problem and he’s found that introducing certain small, but noticeable changes, can make the alerts more useful and harder to ignore.  "Our security UI (user interface) needs to be designed to be compatible with the way our brains work," he said at the USENIX Enigma 2017 conference on Tuesday. "Not against it."To read this article in full or to leave a comment, please click here

Anuta Networks NCX: Overcoming Skepticism

Anuta Networks demonstrated their NCX network/service orchestration product at Network Field Day 14.

Anuta Networks page at TechFieldDay.com with videos of their presentations

Anuta's promise with NCX is to provide a vendor and platform agnostic network provisioning tool with a slick user interface and powerful management / provisioning features.

I was skeptical, especially after seeing the impossibly long list of supported platforms.

Impossible!
Network device configurations are complicated! They've got endless features, each of which is tied to others the others in unpredictable ways. Sure, seasoned network ops folks have no problem hopping around a text configuration to discover the ways in which ACLs, prefix lists, route maps, class maps, service policies, interfaces, and whatnot relate to one another... But capturing these complicated relationships in a GUI? In a vendor independent way?

I left the presentation with an entirely different perspective, and a desire to try it out on a network I manage. Seriously, I have a use case for this thing. Here's why I was wrong:

Not a general purpose UI
Okay, so it's a provisioning system, not a general purpose UI. Setup is likely nontrivial because it requires you to consider the types of services Continue reading

5 Common tech hiring mistakes to avoid

This contributed piece has been edited and approved by Network World editors

Finding the right hire for IT can be a chore, and if you get it wrong, the consequences can be substantial. According to the U.S. Department of Labor, a bad hire costs at least 30% of the initial annual salary, but that number is believed to be much higher. It’s a mistake that companies simply can’t afford to make in today’s increasingly competitive marketplace.

Trump stresses cybersecurity but postpones executive order

U.S. President Donald Trump called on government agencies to better protect their networks, but he delayed signing an executive order to kick-start a government-wide review of cybersecurity policy.A draft copy of the order, leaked earlier, would give the Department of Defense and the Department of Homeland Security 60 days to submit a list of recommendations to protect U.S. government and private networks. Trump had been scheduled to sign the executive order Tuesday but canceled shortly before it was due to happen.To read this article in full or to leave a comment, please click here

Worth Reading: BGP in 2016

Figure 2 illustrates an important principle in BGP, that there is no single authoritative view of the routing table – all views are in fact relative to the perspective of the BGP speaker. It also illustrates that at times the cause of changes in routing is not necessarily a change at the point of origination of the route which would be visible to all BGP speakers across the entire Internet, but it may well be a change in transit arrangements within the interior of the network that may expose, or hide, collections of routes. And thirdly, this illustrates the prevalent use of more specifics to affect traffic engineering. It is often the case that these more specifics are advertised with a limited scope, and if the changes to the transit arrangements move a BGP speaker in or out of this scope, then one can expect changes in the set of visible routes as a consequence. —Potaroo

The $475 S key

I have a Macbook Air, purchased from the Apple Refurb store about two years ago. It now has a dead key. It’s the S key. After cleaning it with compressed air, it worked badly for a while and is now dead. A query to the local Apple repair shop indicates it’s fixable for about $380. One look at the iFixit repair PDF, and it’s easy to see that it’s very labor intensive. For. One. Key. I obtained an appointment at the area Apple Store Genius Bar. After about 40 minutes, it was determined that Apple could repair my MacBook Air. The price would be $475, but that would include other refurbishments as determined at the time, perhaps including a new battery or whatever else was found “wrong” with the machine. To read this article in full or to leave a comment, please click here

Application monitoring becomes table stakes in the digital age

Bill Hineline had two requirements as he was searching last year for a new tool to keep tabs on the hundreds of interconnected applications that keep United Airline's planes flying. It had to ensure critical flight operations software was working and it had to meet customers' demands for accessing information from smartphones and tablets. The airline's director of application performance management also wanted a cloud application rather than another on-premises tool to manage internally.

Illumio extends its segmentation to the network and cloud

Data centers have become increasingly dynamic and distributed, which is why there has been a rise in technologies such as virtual machines, containers and hyperconverged systems.Security has been slow to evolve to meet the needs of the new world, but thanks to innovative start-ups such as Illumio, security is starting to change and is able to meet the demands of digital organizations. One of the big advancements in data center security has been the rise of segmentation tools. In actuality, coarse-grained segmentation has been around for decades in the form of firewalls, VLANs and ACLs, but companies like Illumio and VMware have extended the paradigm to applications, workloads and users. To read this article in full or to leave a comment, please click here
