First steps with Python and Junos

I’m just spending the day trying to get my head around some very basic automation, so I thought I would install Python 2.7 and work through some of the tutorials on the Techwiki to see how I get on.

The tutorial I’m following is called Python for Non-Programmers and offers an easy way in for people like me.  Of course as with a lot of open-source stuff, you don’t just download Python and get started – there are various dependencies, and dependencies with dependencies that you need to install first.  If at the end of all that you’ve not forgotten what your name is or why you were doing all this shenanigans in the first place you can count yourself as winning.

Installation on a Windows machine is documented nicely here, but there are a few things which are out of date.

One part where it tells you run an executable to install ‘lxml’ but there isn’t one when you click the link provided.  So instead you need to install it with a program called pip, which can be found in C:Python27scripts by default.  pip is not in the PATH envirronment variable by default Continue reading

On SDN Controllers, Interconnectedness and Failure Domains

A long long time ago Colin Dixon wrote the following tweet in response to my Controller Cluster Is a Single Failure Domain blog post:

He’s obviously right, but I wasn’t talking about interconnected domains, but failure domains (yeah, I know, you could argue they are the same, but do read on).

The cloned cards were distributed to members of the group who used them to withdraw money from ATMs in different countries, DIICOT said Sunday.To read this article in full or to leave a comment, please click here

The Upload: Your tech news briefing for Monday, April 27

After the earthquake: Tech is a fragile lifeline in NepalIn the first day after a devastating earthquake in Nepal on Saturday, Internet connectivity looked to be an important conduit for bypassing an overloaded telephone network. But by Monday it was clear that large-scale power outages and last-mile Internet connectivity problems were making communications very difficult. The death toll from the quake and numerous aftershocks stands at more than 3,400 people with thousands more injured. Among those killed was a high-ranking Google engineer who was one of a number of expeditioners on Mount Everest who lost their lives in an avalanche triggered by the earthquake.To read this article in full or to leave a comment, please click here

Alibaba looks to rural China to popularize its mobile OS

E-commerce giant Alibaba Group hasn’t given up on its mobile OS, and is taking the software to China’s rural markets through a series of low-cost phones.The company has partnered with mobile carrier China Telecom to sell the YunOS handsets. The eight phones will be built by lesser-known Chinese brands, and will range from 299 yuan (US$49) to 699 yuan.Although Alibaba has its own Android apps that connect to its popular e-commerce stores, the Linux-based YunOS comes with a whole suite of company-developed services.The software, however, hasn’t gained much share in the market. In 2012, Google claimed it was a variant of its Android OS, sparking a clash that threatened to derail Alibaba’s effort to popularize the mobile OS.To read this article in full or to leave a comment, please click here

A year later, Microsoft’s Nokia deal isn’t a clear winner

It was a marriage of convenience for two industry giants whose past successes weren’t helping them win in the red-hot smartphone market. One year later, it’s hard to say that Microsoft’s acquisition of Nokia’s device business has produced the results its backers envisioned.In the wake of the US$7.2 billion acquisition, Lumia smartphones and the Windows Phone OS are still running into many of the same market roadblocks.But Microsoft isn’t throwing in the towel, and has high hopes that its phone business will get a major boost from Windows 10, which is meant to create an environment where users can move easily between desktops, tablets and their smartphones.To read this article in full or to leave a comment, please click here

Review: MacBook Air killer from ASUS

ZenbookAt first glance, you might mistake the ASUS ZenBook UX305 as a dark-gray edition of the 13-inch MacBook Air. It shares nearly the same design cues and size, but is thinner than the Apple notebook is at its thickest point, and weighs less. It also beats many of the current 13-inch MacBook Air’s hardware specs. And it costs less -- a whole lot less – at $699, compared to $999 for the MacBook Air.To read this article in full or to leave a comment, please click here

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
