NetBeez Review

NetBeez presented at Network Field Day 9, where they showed us their solution for distributed network performance monitoring. They gave the delegates a NetBeez agent to take home and test. I’ve run it for the last two months, and I’ve been happy with how it has performed.

Physical Install

The unit was supplied with a US power plug. I was contemplating using an adapter, but I didn’t have any spare power points near where I wanted to install it. Hmmm. Then I realised that the power connection is just a USB port anyway. The Ethernet cable needed to go into my SRX-110, so I wonder if…

Yup! Powers from the USB port on the SRX. Perfect.

Monitoring Setup

The device powered on, and it soon showed up on the NetBeez web dashboard. This is where you can configure your agents, define what tests you want them to run, and see the results.

I added a few simple monitors:

• HTTP monitoring to this website
• HTTP monitoring to www.netopscommunity.net
• PING monitoring to www.netopscommunity.net

All very straightforward to add the monitors, and pick which agents to run them from. Running the same tests from multiple agents gives you a distributed status Continue reading

Yet another blog about Segment Routing-Part 1

In this blog post we will be taking a deeper look at Node/Prefix SID and SR/LDP Interworking. If you work or have an interest in the Routing area, then by this time you may have already heard about Segment Routing (SR) and I am assuming that you already have some awareness with the basic concepts of […]

Video: How waterproof is the Apple Watch?

Ever since the Apple Watch was unveiled back in September, there's been a lot of discussion surrounding how the device might withstand water. In the months leading up to the actual Apple Watch release, there were a few reports indicating that the device was not waterproof, but rather water-resistant. Which is to say, getting a few splashes of water on the device won't ruin it, but it's not something you'd want to go swimming with.Now that the Apple Watch is on store shelves, or available for pre-order to be more exact, the inevitable wave of amateur Apple Watch durability testing has begun. And, as luck would have it, Apple Watch users will be glad to know that their new wearable is much more water-friendly than most initially assumed.To read this article in full or to leave a comment, please click here

What is a non-blocking switch?

How does Internet work - We know what is networking

It is fairly common to hear about switch being non-blocking. It’s because almost all switches today are non-blocking. But what that means? When I asked people around me on what exactly non-blocking switch means, they were unable to get to the same conclusion. I was going through a lot of different internet places and vendor documents before I wrote this here, but, do not hesitate to add something in comments if you have different view on the subject. Line-rate switch means the same as if you would said wire-speed switch. It basically means that this switch has the forwarding capacity that supports concurrently

New Magento WAF Rule – RCE Vulnerability Protection

Today the Magento Security Team created a new ModSecurity rule and added it to our WAF rules to mitigate an important RCE (remote code execution) vulnerability in the Magento web e-commerce platform. Any customer using the WAF needs to click the ON button next to the “CloudFlare Magento” Group in the WAF Settings to enable protection immediately.

Both Magento version 1.9.1.0 CE and 1.14.1.0 EE are compromised by this vulnerability. CloudFlare WAF protection can help mitigate vulnerabilities like this, but it is vital that Magento users patch Magento immediately. Select and download the patch for SUPEE-5344.

Running vSphere on AWS or GCE

By now you’ve probably seen or heard the news about Ravello Systems launching Inception—the ability to run nested VMware ESXi on AWS or GCE, including the ability to run VMs on these nested ESXi instances. (Here’s Ravello’s press release.)

In my opinion, this is pretty cool, and it opens the door to a lot of different possibilities: upgrade testing, automation testing, new feature testing, hosted home labs (aka “Lab as a Service”). Lots of folks are interested in using this new Ravello functionality for “Lab as a Service.” Here’s Andrea Mauro’s take on this topic.

As part of the pre-launch activities, a number of bloggers and community advocates were able to work with Ravello on some very interesting projects:

• William Lam built both a 32-node VSAN cluster (running vSphere 5.5) as well as a 64-node VSAN cluster (running vSphere 6.0). He posted details here, along with a great walkthrough of setting up vSphere on Ravello.
• Mike Preston built out an environment that allowed him to perform a vMotion from AWS to GCE.

I was also engaged with Ravello on a project: building a (reasonably) large-scale vSphere environment on Ravello. The original goal was to Continue reading
