Cloonix network simulator updated to version 26

The Cloonix development team released an update to Cloonix version 26 in May 2015. An important addition in version 26 is a greatly expanded and improved Cloonix user guide.

The new version also changes the user interface, adds a new LAN type, and eliminates the t2t device. It also includes updated guest virtual machines.

User interface changes

In Cloonix Version 26, the user interface eliminates the tool bar and makes all graph objects available via a right-click drop-down menu.

Installing Cloonix v26

The only change to the install procedure is a some new prerequisite software packages that must be installed to support compilation.

You can install pre-compiled binaries or compile Cloonix from source code. I prefer to compile it. The source code and the precompiled binaries are on the Cloonix Software page.

To compile the source code on Xubuntu 14.04, I followed the procedure documented in the Cloonix install documentation.

We will install Cloonix v26 in our Home directory. Download and unpack the source code.

How to Enable Dot1x – more complex setup for wired network

How does Internet work - We know what is networking

This one is long. Do not be afraid though, I made it just to give you the fastest way to deploy functional dot1x to your company HQ without reading even more documentation and searching for those little timer default settings. I the article prior to this I showed you how to setup your environment with simple dot1x and make it as simple as possible. I will not repeat again the part about setting up Radius Clients on server side, everything else is here once again just more complex. Now is time for a more complex example that will make your implementation

Brocade Certified vRouter Engineer

If you’ve visited the Brocade website recently, you’ve probably seen the “Free NFV Certification” banner. I signed up for this several months ago, but had put off completing the course. I had a little downtime recently prior to starting work at Brocade, so I completed this course & exam. Here’s my impressions.

What’s the Course/Exam About?

From the official documentation:

As a Brocade Certified vRouter Engineer, you must be able to demonstrate the ability to install, configure and troubleshoot features of Brocade Vyatta Network OS.

i.e. it’s primarily about the basics of Vyatta.

What’s Included?

Here’s what you get when you sign up:

1. A download link to the Brocade Vyatta 5400 vRouter image.
2. Access to the “Brocade Certified vRouter Engineer Course.”
3. Links to certification materials and communities.
4. Promo code for the BCVRE exam.

Note that you can run the Vyatta image on a local hypervisor, or if you prefer you can select it from the AWS marketplace. Personally I ran it on VMware Fusion on my laptop. It’s light on resource, so you can easily spin up several Continue reading

HTC Fail: Company posts photos of 24-karat gold M9 that were taken with an iPhone

 HTC on Friday took to Twitter to announce a new limited edition 24-karat gold M9 that it's releasing to celebrate Saturday's Champions League final. That's all well and good, but in one of the three photos HTC posted online, it's clear that they were taken with (gasp!) an iPhone.Here's the offending photo.Nothing terribly shocking at first glance, but if we zoom in a little bit on the lower right hand corner on the right-hand device, well, that's an iPhone 6 we see taking the shot.To read this article in full or to leave a comment, please click here

Managed power supplies and how to automate your branch network

One of the worst parts of the day has to be calling AT&T or Comcast to request a dispatch to a branch office or to check up on a problem internet circuit.  Yelling out “Technical Support” to try and get past the prompts.  The first question I get asked every time, “Did you reboot the modem?”. […]

Soviet Mi-24V Hind E, 1/72 scale

For best article visual quality, open Soviet Mi-24V Hind E, 1/72 scale directly at NetworkGeekStuff.

The Mil Mi-24 (Russian: Миль Ми-24; NATO reporting name: Hind) is a large helicopter gunship and attack helicopter and low-capacity troop transport with room for eight passengers. It is produced by Mil Moscow Helicopter Plant and has been operated since 1972 by the Soviet Air Force and its successors, along with more than 30 other nations.

In NATO circles, the export versions, Mi-25 and Mi-35, are denoted with a letter suffix as “Hind D” and “Hind E” respectively. Soviet pilots called the Mi-24 the “flying tank”, or летающий танк (letayushchiy tank). More common unofficial nicknames were “Crocodile” (Крокодил or Krokodil) due to the helicopter’s camouflage scheme and “Drinking Glass” (Стакан or Stakan) because of the flat glass plates which surround the cockpit of the Mi-24.

In my small interpretation, I have used the Revell kid that was released in 2014 targeting the Czech Air Force variant, but it also has the option of doing Soviet markings, so I decided to go with this much more generally known view as I have a certain nostalgia on this thing appearing in the old Operation Flashpoint (2001) by Continue reading

How to Enable Dot1x authentication for wired clients

How does Internet work - We know what is networking

If your LAN is extending to some places where unauthorised people can just plug in and gain access to your protected network, it’s time to implement some security on your access switch. The best thing to do is to implement IEEE 802.1X port-based authentication which will enable users/machine authentication and prevent unauthorized devices from getting access switch port running when connected. IEEE 802.1X port-based authentication is mostly called simply as dot1x. In this article I will show you how to configure some basic dot1x stuff on switch side. I will also include Windows machine side of configuration as this is something most people presume

For its next feat, Google will try to make you eat your vegetables

If your image of the Google cafeteria is a bunch of portly coders tucking into steak and lobster every night, think again: Silicon Valley’s cream of the crop is going on a diet.To the list of perks you’re missing out on at the famous workers’ paradise, you can now add healthier food. But don’t worry, the planet wins, too. For the last year and a half, Google’s food department has been on a mission to cut down on meat.“A more balanced, plant-centric diet is good for the environment and is good for your health,” said Michiel Bakker, director of the Global Food Program at Google. “So if we can move more people to eat less meat and to enjoy more vegetables, the rest will follow.”To read this article in full or to leave a comment, please click here

Apple may reduce its cut of app store revenue for some developers

Apple will begin taking a smaller cut of application revenue from some developers on its App Store, according to a report Friday from the Financial Times.Since the App Store opened in 2008, one of the costs of being an iOS developer has been handing over to Apple 30 percent of an app’s revenue. But the company is now working with media companies including Spotify, Netflix and Time Inc. to give them a larger cut of the sales from their apps, the FT said, citing unnamed sources.It’s unclear what the new revenue split will be, or which companies will be eligible for it, but it marks a departure from the plan Steve Jobs announced when the store first launched.To read this article in full or to leave a comment, please click here

PayPal users may get break on unsolicited robocalls, texts

After a backlash from critics, PayPal seems to be reconsidering a plan to give itself unilateral permission to ping its users with robocalls and text messages.The controversy started when PayPal recently indicated in proposed amendments to its user agreement and privacy policy its intention to engage in this type of communication with its customers. There, it also stated that the only opt-out recourse for those in disagreement with its plan would be to close their accounts.The plan drew attention from critics who, in blogs and on social media, questioned the prudence and legality of the new policy, which is slated to go into effect July 1. If the changes are adopted, PayPal would be able to make autodialed and prerecorded calls, and send text messages using any telephone number account holders have provided to PayPal or that the company has “otherwise obtained.”To read this article in full or to leave a comment, please click here

As PC interest wanes, Computex loses its luster

Taiwan held its 35th annual Computex trade show this week, and the event hasn’t aged well. There was little news to get excited about, the crowds were thinner, and there were no products on the show floor that generated the buzz seen in years past.To be sure, Computex has never had the glitz and glamor of CES, but for the PC industry it’s the big event of the year. Taiwanese companies make most of the world’s PCs—including those sold under more famous brands—and Computex has been a place where Intel and AMD launch new processors, and where competing memory and interface technologies battle for dominance.To read this article in full or to leave a comment, please click here
