BrandPost: The Smart Business Case for Open-Network Automation

Lines of business demand agility, and IT teams that utilize legacy infrastructure and operations face hard limits on how agile they can be. Automating and integrating networking tasks streamlines operations and makes the network much easier to manage, minimizing downtime caused by human error while increasing organizational agility and efficiency. But implementing network-wide automation that also integrates with cross-domain technologies presents three primary challenges.Challenge 1: Vendor Lock-in. Vendor-specific network automation solutions may not completely address your organization’s unique automation needs and they lock you into the vendor's strategy and goals rather than your own. The result is often a flawed approach that doesn’t align and support your organization’s business and technical objectives.To read this article in full or to leave a comment, please click here

IDG Contributor Network: 6 reasons why Slack is the next Netscape

Netscape provides an excellent illustration as to how tech darlings come and go.Netscape created and sold Navigator, the browser that essentially invented the World Wide Web. Prior to Netscape, the internet was mostly benefiting geeks and nerds. Netscape changed the world by transforming the internet into the mass-market, browser-powered online world we know and love today.Netscape’s original business model was to sell licenses for its Navigator browser. It was just over a year old when it had its IPO on Aug. 9, 1995. And in its first day of trading, the stock went from $28 to as high as $74.75, giving the company a value in the billions.To read this article in full or to leave a comment, please click here

Hyperconverged storage: Are your network and team up to the task?

There is reality in the hype that moving to a converged storage environment can produce major cost savings while paving the path to advanced virtualization technologies. Part of the appeal comes from the ability to use commodity servers and storage to build a shared storage pool vs. relying on a dedicated appliance that typically comes at a pretty substantial premium. Increased flexibility is another reason for moving in this direction. IT teams gain greater options in how they configure server and storage nodes to meet workload and application demands. Adjusting configurations is straightforward, so adding more disks to nodes is a pretty easy task. To read this article in full or to leave a comment, please click here

UK official wants police access to WhatsApp messages

A senior U.K. official is asking that law enforcement should be given access to encrypted messages on WhatsApp and similar services, a demand that is likely to fuel an ongoing debate over whether companies should create backdoors into their encryption technologies for investigators.Khalid Masood, the terrorist who killed four people outside Parliament on Wednesday, had sent a message on WhatsApp a little before the attack, according to reports.“We need to make sure that organizations like WhatsApp, and there are plenty of others like that, don't provide a secret place for terrorists to communicate with each other,” Home Secretary Amber Rudd said on BBC One's Andrew Marr Show on Sunday.To read this article in full or to leave a comment, please click here

Configuring Microsoft NPS for Aerohive 802.1X Authentication

This post is a starting point for anyone who wants to use 802.1X authentication with Aerohive APs and Microsoft NPS. I will provide configuration screen shots for both of Aerohive’s management platforms and for NPS running on Microsoft Windows 2008 Server. It is not intended to be an exhaustive guide, but should be a decent starting point. Every implementation will be different in some respect, and some of these steps may not be the exact manner in which you configure Microsoft NPS. The steps for Aerohive may also be different depending on what you are trying to accomplish. I’ll make sure to note my particular scenario when appropriate.

Versions Used:

HiveManager Classic/HM6/HMOL – 6.8r7a

HiveManager NG – 11.19.99.0 (March 2017)

Microsoft Windows 2008 Server

Assumptions:

  1. Basic understanding of navigation within the HiveManager Classic and/or NG interface.
  2. No RADIUS objects or user profiles for 802.1X authentication have been configured within HiveManager Classic or NG. If you have already configured some of them, just skip the steps that cover the creation of those objects.
  3. Microsoft NPS is installed and a server certificate for the NPS machine has been issued and installed.

Scenario

Company XYZ wants to authenticate Continue reading

Learn Programming or Perish(?)

I was honored to return to Packet Pushers for a discussion on programming skillsets in the networking industry. I verbalized some thoughts there, but even 60 minutes isn’t enough for a conversation like this.

To be clear, this post is written primarily to my followers in the networking industry, since that’s largely where this conversation is taking place.

Scripting is NOT Programming

I want to put something to rest right now, and that is the conflation of scripting and software development. You may be hesitant to pick up any skills in this area because you feel like you have to boil the ocean in order to be effective, which is not true.

As I briefly mention in the podcast, I spent the first 4 years or so of my career making networking my day job. Because of that, I picked up a lot of useful knowledge in this area. However, as I started to explore software, I realized that networking wasn’t something I wanted to do as a day job anymore, but I still greatly value the networking skillset I retain from this experience.

Making this leap over 2 years ago revealed a multitude of subskills, fundamental knowledge, and daily Continue reading

iPhone 8 release date still anticipated for September

As is par for the course in the build-up to any new iPhone release, we've been seeing a lot of conflicting information surrounding Apple's highly anticipated iPhone 8. Over the past few weeks, we've seen quite a few reports claim that the iPhone 8 release date might be pushed all the way back to November due to a more complex manufacturing process.Most recently, a report surfaced just a few weeks ago claiming that iPhone 8 production might be delayed due to the time needed for STMicroelectronics (one of Apple's manufacturing partners) to produce enough 3D camera modules to meet what will unquestionably be remarkably high, if not unprecedented demand.To read this article in full or to leave a comment, please click here

Microsoft axed Docs.com search option after private files were shared publicly

Docs.com, Microsoft’s site which is described as “showcase and discover Microsoft Word, Excel, PowerPoint, OneNote, Sway and PDF document for free,” came under fire over the weekend as Twitter users started complaining that users of the site had inadvertently shared private and sensitive information with the world.The site had a search functionality which would allow anyone to search through millions of files.

Yet after people started tweeting screenshots of sensitive information, Microsoft quietly removed the search functionality on Saturday.To read this article in full or to leave a comment, please click here

Update: Virtual Switches in vSphere Environment
