Nice use of VMware Fusion in part 2, by the way.). VMware, Vagrant, and Docker together is the subject of this blog post by Fabio Rapposelli. I find it enormously helpful to stay connected to various open source-related IRC channels, but staying logged while on the move is, for all intents and purposes, impossible.

I recently came across a couple useful troubleshooting guides, one for Open vSwitch (OVS) and OpenStack Neutron and one for VMware NSX. Matt Oswalt recently unveiled (and open sourced) a framework called ToDD, which stands for “Testing on Demand: Distributed”. VMware recently GA’d version 6.2 Servers/Hardware.

Jason Edelman has posted a self-compiled list of networking projects that are open source ; this is a useful list, so thanks for compiling it Jason! I didn’t think that OpenFlow itself was actually open source (even though there are multiple open source implementations of various OpenFlow products).

I think a fair number of folks may not be aware that the Nginx ingress controller for Kubernetes—both the community version and the Nginx-maintained open source version—do suffer from timeouts and errors resulting from changes in the back-end application’s list of endpoints (think pods being added or removed).

Dmitri Kalintsev is back with another article in a series of articles on using hardware VXLAN tunnel endpoints (VTEPs) with VMware NSX. Here’s a handy post by Dale Coghlan on how to find object IDs for just about anything in a VMware NSX environment. In this case, it’s on validating HW VTEP deployment for integration with NSX.

This article by Joshua Fox outlines how and when to use each of the various types of firewalls offered by AWS. The popular open source cryptography library known as Bouncy Castle has uncovered a severe authentication bypass vulnerability. Jason Eckert provides an introduction to using WireGuard for VPN connectivity.

We all know that security is more than just a host-based firewall, but a host-based firewall can be part of an overall security strategy. This article provides a good introductory overview of Linux iptables commands for configuring host-based firewall rules on your Linux systems. Cloud Computing/Cloud Management.

Well, let’s see…stuff on Envoy, network automation, network designs, M1 chips (and potential open source variants!), Ivan Pepelnjak shares some links and thoughts on configuring the NSX-T firewall with a CI/CD pipeline built on GitHub Actions and Terraform Cloud. Are open source M1-style chips a possibility?

Skydive is (in the project’s own words) an “open source real-time network topology and protocols analyzer.” Tony Sangha took PowerNSX (a set of PowerShell cmdlets for interacting with NSX) and created a tool to help document the NSX Distributed Firewall configuration. What’s that? You haven’t heard of PowerNSX before?

Thinking of using a hardware VTEP (VXLAN Tunnel Endpoint) with VMware NSX? VMware recently announced Open Hardware Management Services (OHMS) , a project intended to help manage servers and switches in a software-defined data center (SDDC) context. The issue lies with VMware Tools, apparently; see Jason’s post for full details.
