Container Networking Tutorial
Yesterday I delivered a tutorial as part of the Open Network Users Group (ONUG) Academy: To go through the tutorial yourself you’ll need an AWS account and an SSH client (and the Internet access and browser you’re using to read this). To complement the slides there’s a wiki on GitHub with all of the relevant command […]

At last week’s Ignite conference Microsoft announce a set of new networking capabilities for its Azure cloud described as being ‘for a consistent, connected and hybrid cloud’. The new capabilities include improvements to ExpressRoute, Azure’s Internet bypass offering, availability of ExpressRoute for SaaS offerings such as Office 365 and Skype for Business, additional VPN capabilities […]

NAT in the hat
TL;DR Whilst on vacation in Spain I’ve found networks that seem to be like something out of a Cory Doctorow novel – domestic WiFi routers hanging off domestic WiFi routers hanging off domestic WiFi routers. At first I thought it was my Airbnb host being cheap and having a cosy arrangement with a neighbour to […]

OpenWRT on TP-Link WR-703N
The TP-Link WR-703N is a nice, hackable pocket WiFi router. I’ve seen them put to some interesting purposes, but I didn’t own one until yesterday when the kind folk at QCon Shanghai gave me one. I’m not a fan of factory TP-Link firmware at the best of times, but more so when it defaults to […]

The WRTnode is a great new open source hardware dev board that takes the guts of a typical home router and makes it hackable. It’s more than an Arduino, less than a Raspberry Pi, and very network capable. WRTnode runs the OpenWRT Linux distribution, which I’ve used in the past on some of my home […]

Weave is an overlay networking system for Docker containers. Whilst Docker can already link containers on a single host, Weave provides connectivity for containers that are spread across multiple hosts. It has been released under the Apache 2 open source license by Zettio, a new company targeting ‘apps for the zettabyte era’ founded by RabbitMQ […]

One of the big news items from last week’s VMworld was the launch of EVO:RAIL, a ‘hyperconverged infrastructure’ reference design with software from VMware and hardware from a variety of partners. The RAIL part of the name comes from the smallest unit of deployment that fits into 2U of standard rack space, and onto a […]

This post originally appeared on the CohesiveFT blog The Docker subsystem available since version 3.5 allows additional virtualized network functions (VNFs) to be run on VNS3. I’ve previously written about using this capability for content caching, SSL termination and load balancing. This time I’ll cover using it as a network intrusion detection system (NIDS). Introducing Suricata […]
