SSH is a BAD API

Okay, so its not meant to be an API. I get that. I’ve been watching a rather good video about executing interactive commands with Parimiko and two thoughts came to my mind.

• Very powerful/flexible way to do tasks across many devices
• This could be a LOT easier if we simply had the RESTful API’s we want everywhere

In any case, I think the video below is a worthwhile watch if you’re struggle to leverage Python and SSH to make a modification across a large number of devices.

The LeEco Le Pro 3 Ecophone; an Android smartphone definitely worth considering

It takes a brave company to attempt to gain a serious foothold in the U.S. smartphone market given that the dominant players are so massive and entrenched but that apparently wasn't a concern of LeEco when the company launched its products at the end of 2016. And rather than just selling smartphones, LeEco’s market approach is to become a lifestyle brand and claims that: LeEco seamlessly blends devices, content, applications and distribution in a first-of-its kind ecosystem. This innovative approach puts extraordinary experiences in the hands of millions of people all over the world. Pretty ambitious stuff but perhaps not surprising as LeEco is notable for being aggressively innovative and their product lines include televisions (the company acquired U.S. television manufacturer Vizio last year), headphones, speakers, chargers, phone covers, and there’s the LeEco Super Bike (with built-in fingerprint sensor ID and a waterproof touchscreen Android display). But wait! There’s more! They’ve even showcased a high-tech, self-driving concept car. To read this article in full or to leave a comment, please click here

Automation: Build or Consume?

The question of “home grown vs. off the shelf” comes up a lot. It comes up both in a professional capacity and social.

Home grown, usually born out of frustration to solve an immediate problem, often is a path that leads to consuming something off the shelf either Open Source or commercial. Home grown can deliver rapid results for simple things but has an exponential learning growth curve to do something more complex.

Why learn the oddities and nuances of a full programming language to write a multi-threaded application that automates concurrently, when you can write simple instructions that makes something else takes care of all of that mucking about in parallelism, logging and worrying about covering every use case. If you like hacking and building things, is it not better to apply that yearning solving rapidly rewarded challenges or to work on building something that starts off fragile and like all babies, has to learn to crawl, walk and be weened off milk?

Good tools deal with things like input, decision making and invoking output. It’s always better to control the pipeline and write linkages than to build the whole thing. After all, the problem with software is, you Continue reading

Starting SDN Learning Journey- Through Open vSwitch

Introduction

Software Defined networking (SDN) is no more a new topic but still many Network/ System engineers feel it painful how to start learning SDN. Many SDN solution exists in market and each has its pros and cons. Objective of this blog is to give an idea about SDN basics to the engineers who want to start their SDN learning curve.

Reference topology

• 2 x Ubuntu host (14.04 LTS) each with multiple NICs
• Open vSwitch installed in each host and 1 instance created.
• Virtual Box installed in each host, vBox will be used to host guest virtual machines (VM-A & VM-B)

Topology Description

Open vSwitch (e.g br0) in each host will have following interfaces:-

• A tap interface which will be used to bind guest VM to Open vSwitch
• Eth1 of each host will be added to Open vSwitch
• IP address / sub netmask for Eth1 of each host will be configured on Open vSwitch itself (br0)
• Guest VM eth1 will be configured with IP/sub net mask different that host IP/ sub net mask
• VXLAN / GRE will be configured on each host (by using host IP addresses)

Step by Step setting up Lab

It is assumed Ubuntu 14. Continue reading

TIP: How To Do MD5 and SHA1 File Checksum Validation

It’s always a good idea to calculate an MD5 or SHA1 file checksum to validate file integrity after download or transfer, especially when dealing with firmware binaries. While most modern systems are smart enough to validate images before attempting an installation, not all are so wise, and I’m sure I’m not the only one to have seen a device bricked (or stuck in ROMMON or a similar bootloader or equivalent) after a bad image was uploaded.

Here’s a quick reference guide to creating file checksums on Macos (OSX), Windows and Linux.

File Checksum Validation

There are various ways to check md5/sha1 checksums depending on your preferred platform. Vendors tend to publish the MD5 or SHA1 checksums (or both) for downloadable files, so it’s silly not to do checksum validation and confirm that the file has downloaded completely and uncorrupted. I try to validate after each time I transfer a file so that I don’t waste time sending a corrupted file on to the next hop. For example:

• Download image file from Cisco’s website
• — View the checksum and compare
• SCP the file to a target jump server
• — View the checksum and compare
• SCP the file to the end device

Data, Analytics, Probabilities and the Super Bowl

Data is quickly becoming the coin of the realm in most aspects of the business world, and analytics the best way for organizations to cash in on it. It’s easy to be taken in by the systems and devices – much of the discussion around the Internet of Things tends to be around the things themselves, whether small sensors, mobile devices, self-driving cars or huge manufacturing systems. But the real value is in the data generated by these machines, and the ability to extract that data, analyze it and make decisions based on it in as close to real-time as …

Mozilla zaps residue of Firefox OS as it shutters IoT group

Mozilla confirmed that it is shuttering a group tasked with creating an operating system for connected devices, the category pegged as the "Internet of things," or IoT.It was the second defeat in 14 months for Mozilla projects aimed at producing commercial hardware products."We have shifted our internal approach to the IoT opportunity to step back from a focus on launching and scaling commercial products to one focused on research and advanced development," a Mozilla spokesman said in an email reply to questions. The open-source developer will dissolve its connected devices project, and will instead "incorporate our IoT explorations into an increased focus on emerging technologies."To read this article in full or to leave a comment, please click here

Lawsuit claims Apple broke FaceTime to force iOS 6 users to upgrade

Did Apple purposefully break iOS 6, rendering old iPhones unusable before their time? That’s the question at the heart of a new class-action lawsuit against the Cupertino company, which claims that Apple killed FaceTime in iOS 6 to avoid paying hefty licensing fees.The basis of the lawsuit, first reported by AppleInsider, comes from details that emerged last year in VirnetX’s patent infringement suit against the company. VirnetX licenses patents to technology companies, and one of those patents covers peer-to-peer audio and video transfer; Apple used peer-to-peer transfer to power FaceTime. When VirnetX, which has been described as a “patent troll,” came after Apple, the company switched to another relay method for FaceTime, using the third-party server Akami. That’s where things get tricky. Apple had to pay Akamai for that server usage to the tune of millions and millions of dollars. Faced with VirnetX’s patent infringement court win and mounting Akamai bills, Apple created a new peer-to-peer protocol for FaceTime in iOS 7.To read this article in full or to leave a comment, please click here

AT&T will prove 5G using open-source SDN technology

The blazing fast speed and low latency of 5G could suffer from the same obstacle that Gig-internet access does: a scarcity of apps that demonstrate its capabilities. Case in point: The Chattanooga municipal power company EPB slashed the price of Gig-internet to $69.95 per month because many customers opted for slower 100MB service at $59.95 because typical mobile and PC apps do not showcase the benefits of the top speed offering.It is a chicken and egg problem, or more aptly the chicken and the app problem. Without high-speed infrastructure, apps cannot be built that demonstrate the capabilities of 5G. And without apps, infrastructure will not reach cost effectiveness and be deployed at scale. 5G will not scale without distributing the cloud platforms into the network infrastructure running on software-defined networking (SDN) commodity hardware.To read this article in full or to leave a comment, please click here

UK defense secretary urges NATO to fend off Russian cyberattacks

The U.K.’s defense secretary is accusing Russia of using cyber attacks to “disable” democratic processes across the West, and he's demanding that NATO fight back.“NATO must defend itself as effectively in the cyber sphere as it does in the air, on land, and at sea,” Defense Secretary Michael Fallon said. “So adversaries know there is a price to pay if they use cyber weapons.”Fallon made the comments in a Thursday speech about the threat of “Russia’s military resurgence.”He pointed to the Kremlin’s suspected role in influencing last year’s presidential election in the U.S., as part of growing number of alleged cyber attacks that have targeted Western governments.   To read this article in full or to leave a comment, please click here

IDG Contributor Network: A guide to hybrid cloud transformation

Enterprises have made it clear that when it comes to cloud computing, one size does not fit all.  What we’re hearing from the market is the need for consistency with choice, otherwise known as a balanced cloud platform. Unique business needs, along with security, geography and regulatory considerations, dictate a mixing and matching of both public and private cloud solutions—thus the rise of hybrid.Case in point, Forrester surveyed 1,000-plus North American and European enterprise decision makers and found that in the next 12 months 38 percent are building private clouds, 32 percent are building public clouds, and 59 percent are adopting a hybrid model.To read this article in full or to leave a comment, please click here
