Today on the Weekly show, MPLS in the enterprise, especially for the use case of segmentation.

Should you do it? Why would you do it? Considering the equipment you ve got, could you do it even if you wanted to? And even if you should, you would, and you can, what about all those other people you work with?

Discussing this emotionally fraught topic of MPLS in the enterprise is Tom Ammon, a senior network engineer who s supported it in a few different environments. He blogs at blog.tomammon.net.

We start by discussing the general case for MPLS in the enterprise, walk through the hardware and software requirements necessary to support MPLS, and then drill into segmentation more specifically.

We also look at reasons why you’d want to use MPLS for segmentation, and explores issues around operations, skillsets and training, and troubleshooting.

In January 2018, the WiFi Alliance announced that WPA3 was coming this year, a collection of security enhancements to address issues with WPA2.

Today, we discuss WPA3 with Dan Harkins, a scientist at Aruba Networks, a Hewlett Packard Enterprise company. Dan has been closely involved with WPA3 s development, and I heard Dan present on his work at Aruba Atmosphere 2018 in March of this year.

Dan was kind enough to join us today for a preview of what s coming, with a special focus on one aspect of WPA3 that interests me personally, Opportunistic Wireless Encryption (OWE).

We also discuss the fixes that WPA3 makes to WPA2, and when we can anticipate product support.

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.

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
