Install Netmiko on Windows

Netmiko develop by kirk Byers is open source python library  based on Paramiko which simplifies SSH management to network devices .

Netmiko library  makes task to automate . Its very tedious to find out the procedure to install Netmiko in Windows enviornment.Let’s make out task simple :-

Steps:

• Install Anaconda ( https://www.anaconda.com/download/)
• From the Anaconda shell, run “conda install paramiko”.
• From the Anaconda shell, run “pip install scp”.
• Install git for windows (https://www.git-scm.com/downloads)
• Clone Netmiko from Git Bash Window (https://github.com/ktbyers/netmiko).
• Change directory to netmiko.
• Run  python setup.py install from Git Bash Window
• Check on Python console to confirm the availabilty of paramiko and netmiko library

Its done.. Enjoy automating tasks !!!!

ForkBase: an efficient storage engine for blockchain and forkable applications

ForkBase: an efficient storage engine for blockchain and forkable applications Wang et al., arXiv’18

ForkBase is a data storage system designed to support applications that need a combination of data versioning, forking, and tamper proofing. The prime example being blockchain systems, but this could also include collaborative applications such as GoogleDocs. Today for example Ethereum and HyperLedger build their data structures directly on top of a key-value store. ForkBase seeks to push these properties down into the storage layer instead:

One direct benefit is that it reduces development efforts for applications requiring any combination of these features. Another benefit is that it helps applications generalize better by providing additional features, such as efficient historical queries, at no extra cost. Finally, the storage engine can exploit performance optimization that is hard to achieve at the application layer.

Essentially what we end up with is a key-value store with native support for versioning, forking, and tamper evidence, built on top of an underlying object storage system. At the core of ForkBase is a novel index structure called a POS-Tree (pattern-oriented-split tree).

The ForkBase stack

From the bottom-up, ForkBase comprises a chunk storage layer that performs chunking and deduplication, a Continue reading

AMD’s EPYC server encryption is the latest security system to fall

It’s a good thing AMD had the sense not to rub Intel’s nose in the Meltdown/Spectre vulnerability, because it would be getting it right back for this one: Researchers from the Fraunhofer Institute for Applied and Integrated Safety in Germany have published a paper detailing how to compromise a virtual machine encrypted by AMD's Secure Encrypted Virtualization (SEV).The news is a bit of a downer for AMD, since it just added Cisco to its list of customers for the EPYC processor. Cisco announced today plans to use EPYC in its density-optimized Cisco UCS C4200 Series Rack Server Chassis and the Cisco UCS C125 M5 Rack Server Node.To read this article in full, please click here

Is open source software a network security risk?

Networks are changing. More and more we’re hearing terms like whitebox, britebox, disaggregation, NOS, commodity hardware and open source when we talk about the future of networking. Since you’re reading this on the Cumulus Networks blog, I’ll assume you get that and spare you a description of these terms here. If you do want a crash course on network disaggregation and how it relates to orchestration/SDN, check out my previous post on the Packet Pushers blog.

With that bit of housekeeping out of the way, let’s dig right into today’s topic: open source software security.

First, why does security matter? If you’re like most network engineers, your primary goal typically is to get bits of data from one place to another. Anything that interferes with the free flow of packets and frames is a potential problem. So the goals of security can at first appear contrary to those of the network. Raise your hand if you’ve ever been frustrated by a firewall rule or some seemingly arcane security policy!

Unfortunately, we no longer have the luxury of ignoring security. Today’s network is one of the most crucial pieces of IT infrastructure for any organization and for the economies we operate in. Continue reading

Viewer’s Guide: Virtual Cloud Network Online Event

Start Building the Virtual Cloud Network Today, join the online event June 5 at 11am PDT

---

You might not know it yet, but your network is holding you back. Unconnected clouds and data silos prevent your enterprise from securing and mining valuable data. VMware creates connections from your data center to the cloud to the edge – providing a secure, consistent foundation that drives business forward, rather than holding it back.

VMware recently announced our vision for the next era of networking – the Virtual Cloud Network. Join us for an exclusive online event to learn about how your organization can start building the network of the future. To prepare for this event, I not only spent time with the customers, technical leads and executives you hear from, but also behind the scenes, I have been part of many more conversations that I was not able to share.  Pulling from those conversations, I’ve created your viewer’s guide for each segment of the event.

 

An overview of the Virtual Cloud Network by Rajiv Ramaswami, Chief Operating Officer, Products and Cloud Services

Rajiv and Pat share their executive views on the Virtual Cloud Network at the beginning of the event. To Continue reading

The First Lady’s bad cyber advice

First Lady Melania Trump announced a guide to help children go online safely. It has problems.

Melania's guide is full of outdated, impractical, inappropriate, and redundant information. But that's allowed, because it relies upon moral authority: to be moral is to be secure, to be moral is to do what the government tells you. It matters less whether the advice is technically accurate, and more that you are supposed to do what authority tells you.

That's a problem, not just with her guide, but most cybersecurity advice in general. Our community gives out advice without putting much thought into it, because it doesn't need thought. You should do what we tell you, because being secure is your moral duty.

This post picks apart Melania's document. The purpose isn't to fine-tune her guide and make it better. Instead, the purpose is to demonstrate the idea of resting on moral authority instead of technical authority.

Strong Passwords

"Strong passwords" is the quintessential cybersecurity cliché that insecurity is due to some "weakness" (laziness, ignorance, greed, etc.) and the remedy is to be "strong".

The first flaw is that this advice is outdated. Ten years ago, important websites would frequently get hacked and Continue reading

Worth Reading: The perfect blog post

How long should a blog be? The infinite Internet has done away with strict word counts and in theory, every online article can be as long as the author feels necessary to get their point across. Unfortunately, many bloggers forget the second part of the old joke relating to dresses and speeches: they should also be short enough to be interesting! —Dominic Jeff @Web Designer Depot

Connect Ansible Tower and Jenkins in under 5 minutes

We often hear from customers that they are using Jenkins in some capacity or another. And since I'm a consultant, I'm lucky to hear first hand what our customers are using and how they need to integrate Ansible Tower. There has always been a way to integrate the Ansible Tower and Jenkins using tower-cli, but I thought there could be a neater, closer to native, way of doing it.

So here we go. I've recorded this short screencast to show you just how easy it is:

Below you will find a few links from the video and a link to how to try Ansible Tower.
