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.

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. I just noticed this article about using Nova flavor extra-specs to pass QoS data down to the virtualization layer. Here’s a walkthrough to install Arch Linux on VirtualBox.

In the event you’re interested in an idea of how much latency the use of in-kernel hypervisor firewalling (such as that offered by VMware NSX) adds, have a look at this article by Sean Howard. What really caught my eye, though, was the size of the Windows Server Docker image (9.429 GB!). Virtualization. Servers/Hardware.

In the event you accidentally locked yourself out of vCenter using NSX’s distributed firewall, this post by Roie Ben Haim provides a workaround for getting yourself out of this pickle. This is a highly technical article on scheduling in the Linux kernel , but it’s well worth reading. Virtualization. This would be one reason.

It effortlessly integrates with any area of the IT infrastructure, be it provisioning virtual machines (VMs) or creating firewall rules. Moreover, Ansible comes in handy with aspects that other tools leave gaps in, such as zero-stop and continuous updates for multitier applications across the infrastructure.

This article by Russell Bryant is a great overview and update of the work going on with Open Virtual Network (OVN). 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).

To access these sections of the building, there have to be doors, too, and behind these doors are the various companies, the various cloud clients with all their various virtual machines that can be spun up or spun down. You simply send an HTTP request and retrieve unique information per Virtual Machine (VM). You don't have to.

I’ve written before about adding an extra layer of network security to your Macintosh by leveraging the BSD-level ipfw firewall, in addition to the standard GUI firewall and additional third-party firewalls (like Little Snitch ). The robust pf firewall should now be running on your OS X Mountain Lion system.

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.

That meant I tested the release candidates -- not the final product you’d buy in the stores - for consumer-grade antivirus programs, desktop firewalls, and desktop Intrusion detection systems. After testing Unix, Miller went to fuzz Windows NT and other systems. And while it’s not Windows, it can be added.
