Networking. Michael Kashin has a great article on how Open Virtual Network (OVN, part of the Open vSwitch project) implements virtual networks in OpenStack. In a bit of an older post from late summer 2016, Matt Oswalt outlines why network engineers should care about the network software supply chain. Good advice.

I wouldn’t take this information as gospel, but here’s a breakdown of some of the IPv6 support available in VMware NSX. Welcome to Technology Short Take #84! OK, bring on the links!

Networking. Vincent Bernat has a really in-depth article on IPv4 route lookup on Linux (and one on IPv6 route lookup as well). Ivan Pepelnjak has a great article that tries to get to the kernel of truth in the middle of the intent-based networking hype. The company is VirTool Networks (catchy, eh?),

For small or uncomplicated networks, BIND by itself is well suited to provide all DNS-related service functions. Typically, the people who manage BIND DNS servers day to day are network administrators or system administrators who are comfortable in Linux/UNIX. Who Uses BIND? Benefits of Using BIND. BIND is customizable.

That prompted Cody Bunch to write this article on setting up a topology with BGP on Linux using the topology converter , which I’m now mentioning in this Technology Short Take.

Networking. I love this post from Matt Oswalt on five next-gen skills for networking pros. It tells me that some skills—specifically, Linux, automation/configuration management, software development concepts—are going to be essential for all new IT pros in the near future. Here’s hoping you find something useful. You’re welcome.

Networking Kevin Jin’s post on the APNIC blog about network automation tools is a great read. He discusses Netmiko, NAPALM, and Nornir in some detail, and provides some guidance around which network automation tool may be right for you. Anton Kuliashov writes about why Palark uses Cilium for Kubernetes networking.

Wireguard, if you’re not familiar, is a relatively new solution that is baked into recent Linux kernels. Since the configuration of the clients and the servers is largely the same (especially since both client and server are Linux), I haven’t separated out the two configurations. There is also support for other OSes.)

Networking. Michael Ryom has a nice (but short) article on using Log Insight along with a NetFlow proxy to help provide more detailed visibility into traffic flows between VMs on NSX logical networks. BGP seems to be emerging as an early front-runner for a standards-based control plane for software networking. Servers/Hardware.

Perhaps there was a bulletin board behind it, or perhaps there was a corporate network. We try to understand as much as possible about the network protocol and the malicious activity that this particular malware does. So we have far less users for Mac and Linux than we have on Windows.
