At DevOps Networking Forum 2016, I had the opportunity to share a presentation on some Linux networking options. At the recent OCP Summit, Microsoft introduced Software for Open Networking in the Cloud (SONiC). Russell Pope at Kovarus recently wrote about using security groups to manage the VMware NSX distributed firewall.

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. Look no further.

The use of VMware NSX for microsegmentation is a really popular use case, and so the topic of scripting distributed firewall (DFW) rules often comes up. Cloud Computing/Cloud Management. In any case, have a look at this article by Julio Villareal Pelegrino on architecting an OpenStack cloud. No pun intended!)

It was good to read this post on Cumulus Linux first impressions by Jeremy Stretch. I’m a fan of Cumulus, but I’m admittedly a Linux guy (see here ) so you might say I’m a bit biased. Jeremy is a “hard-core” networking professional, and so hearing his feedback on Cumulus Linux was, in my opinion, useful.

This is kind of cool, and (in my humble opinion) a sign of changing times: Juniper has Vagrant boxes as well as a Vagrant plugin for working with vSRX (virtual firewall) VMs (via this article from Matt Oswalt).
