Networking. Isovalent, the folks behind Cilium, recently unveiled the Network Policy Editor, a graphical way of editing Kubernetes Network Policies. Ivan Pepelnjak, the font of all networking knowledge, has been discussing cloud networking in some detail for a good while now. Want/need to better understand IPv6?

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.

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.

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?),

This is a liveblog of the OpenStack Summit Sydney session titled “IPv6 Primer for Deployments”, led by Trent Lloyd from Canonical. IPv6 is a topic with which I know I need to get more familiar, so attending this session seemed like a reasonable approach. And a /64 prefix is considered a single local network.

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.)

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.
