Network Break 183: VMware Embraces Cloud Networking; Cisco Acquires Accompany
Take a Network Break! VMware announces its Virtual Cloud Network vision and outlines the product portfolio to bring that vision to life. Dell Technology World showcases new servers and storage and cements Dell’s one-stop-shop strategy. Cisco spends $270 million to buy relationship intelligence purveyor Accompany.
Cisco also shed its service provider video business, Anuta Networks makes its orchestration platform available as SaaS, and the Lojack laptop recovery software suffers a serious vulnerability.
Meanwhile, a Webex vulnerability enables remote code execution, Arista shares dip despite a strong quarter, and Juniper shares rise slightly despite a poor one.

PQ 148: How To Monitor Cryptojacking With Paessler PRTG (Sponsored)
Today on Priority Queue, the Packet Pushers peer into the darker corners of network monitoring.
Monitoring gets you visibility. But when you can see what’s happening, you might not like what you find. That s the topic of today s sponsored show with Paessler AG, maker of PRTG network monitoring software.
Our guests are Greg Ross, Presales Systems Engineer at Paessler; and Troy Mursch, a security researcher who blogs at Bad Packets Report.
Troy discovered that cryptojacking malware called Coinhive had infected a popular Website. We’ll talk about how he used Paessler sensors to monitor the malware on the site, and to track down other infected systems.
We talk with Troy and Greg about how to use Paessler to monitor key metrics that could indicate malware. We also dig into Paessler’s capabilities for more typical network monitoring use cases.
And here’s a special offer for Packet Pushers listeners: Paessler is offering a free network security eBook. You can get it at go.paessler.com/packetpushers.
You can also get a free trail of PRTG here.

Datanauts 132: Unit Testing For Fun And Profit
While performing a routine sensor sweep of the Gargleblaster nebula, the crew of the Datanauts starship noticed that many of the tasks are manual in nature and could, with a little effort, be automated with some scripting.
However, every time we moved on from one part of the nebula to another, a different error would crop up with the script s code. Isn t there some way that we can automatically test our code to make sure that more time is spent drinking a frothy ale instead of all this debugging?
On today’s episode with talk with Adam Bertram, a Microsoft MVP and author of The Pester Book.
He is currently a Senior Systems Automation Engineer working with PowerShell, Desired State Configuration, and various other DevOps tools to coordinate reliable software deployments for a biotech company. You can find his work at adamtheautomator.com.
We start by defining a unit test for scripts, and how unit testing differs from integration, functional, regression tests, and others.
Then we dive into why you’d want to test your scripts (testing isn’t just for developers!), and how to create these tests.
We also talk about the notion of test-driven development, and dive Continue reading

In this episode of Packet Pushers, it’s AWS networking. You use AWS and think you know what you need to know? Maybe, but our guest today can probably share a thing or two you didn t even know were things when it comes to networking in the Amazon public cloud.
Our guest is Nick Matthews, Principal Solutions Architect at Amazon Web Services. Nick focuses on networking and security.
Nick pinged us, hoping to share his perspective on cloud networking from the inside. Come and have a look.
We talk about how networking basics do–and don’t–map to the cloud, and how the architecture of cloud applications influence network design and operations.
We also explore AWS networking elements under the hood, such as Hyperplane, and how trends such as SD-WAN and SDN influence Amazon networking.

PQ 147: Connecting Security And GDPR Compliance (Sponsored)
On this episode of Priority Queue, which is sponsored today by Cisco, we tackle the General Data Protection Regulation, or GDPR.
This new regulation lays out data privacy and protection obligations for organizations that handle data of EU citizens, including loss prevention, breach notification requirements, and serious fines and penalties for violations.
We delve into GDPR requirements with Equilibrium Security and ePlus/IGX Global, two Cisco partners who share practical insight and advice for dealing with GDPR.

Today on the Datanauts podcast, we land on planet Mentorship to drive around in our exploratory rovers. Why? Mentoring came up on Twitter a while back.
Some of you are for it. You invest in your co-workers and your organization by sharing with others what you know. Some of you are against mentoring, arguing that you don t have the time and aren t getting paid to teach other people.
And then the Twitterverse connected us to Don Jones, who wrote a book called, Be The Master. Seems like a great excuse to fire up the microphone on our rovers and explore planet Mentorship in more detail.
Besides being an author, Don is an an IT pro and PowerShell expert who has created a variety of PowerShell training materials.
We talk about how a master/apprenticeship approach can be more effective than formal education, selfish reasons for being a mentor, how to address imposter syndrome, and how to get support for mentorship at work.
