‘Hello world’ for network engineers exploring Hadoop
It is hard to ignore all of the hype around Hadoop and Big Data these days. Like most infrastructure engineers, we tend to focus on how to build highly-available, highly-scalable networks – and I’m no exception. However, it is still important to me to keep up with and implement projects on popular trends, directly infrastructure […]

On IPSec complexity – maybe AWS VPC’s IPSec will emerge as a de-facto standard
Here is a delayed reaction to the posts about IPSec complexity by Jason Edelman and Ivan Pepelnjak last month. AWS might give us decent IPSec ‘standard’ to rally around. There has been plenty of discussion of the past few years about whether it’s a good idea for providers and orchestration stacks to adopt the AWS APIs. There’s no need to […]

Show 166 – SDN Controller Strategies
We know that networking for last few months is all about SDN Unicorns and other Applications. This week we are joined by Mike Dvorkin and Brent Salisbury to talk about the science of building SDN controller application. It's not easy to decide how to build a model that allows for business policy to map onto flow management, virtual server and physical devices so we gathered in the virtual boardroom to discuss the fundamental nature of SDN Controller and basic concepts of what you want to build and why.

Remote LFA
In the last episode in our world wide tour of fast reroute mechanisms, we discussed Not-Via. While an interesting concept, Not-Via does require a number of extra IP addresses, as well as a new set of special routing advertisements, to work properly. So while Not-Via is conceptually simple, it hasn’t ever really been accepted as […]

Cisco IPsec VPN breakage on Windows 8[.1] and OS X 10.9
Oh, to be a Cisco IPsec VPN user these days… Now I know that we should get with the program and move to AnyConnect, since Cisco is EOL-ing the venerable Cisco VPN Client in 2014, but we have a large installed base, and since Cisco stopped making IPsec clients for Mac and Linux back in the […]

Securing a DMVPN spoke – Part 2
In Part 1 we went through protecting the spoke from the outside world on the Internet and using the stateful inspection firewall CBAC, Content-Based Access Control, to dynamically allow returning traffic back in. CBAC works great for a single inside zone and a single outside zone. What if your business requirements have more than two […]

F5 LTM Encrypted Cookie Insert Persistence
The purpose of a load balancer is to distribute client connections to multiple servers to increase load capacity and provide high availability. One common requirement of load balanced applications, since most application servers maintain session information on the local box, is that a client must stay locked to a single server for the duration of […]

Back to the Basics…
Now that I’ve finished learning about SDN, and then studied for and passed my latest Cisco certification (CCNA Security, keeping that vendor certification path open!), I’ve gotten into the groove of studying at night (and I as I love IT, and specifically networking, it’s kinda become my hobby… I know, lame, right?) In any case, […]

Bash and Net-SNMP: a low budget, high frequency SNMP poller
Introduction Note: This assumes you’re on a linux machine, but it should work on any box where you can install and run Bash, for example windows with Cygwin. (You’ll also need the date program from GNU Core Utilities too, but that’s installed by default on any normal Linux or Cygwin system.) Note: For simplicity the […]

Stateless Routing Through an in-line F5 LTM
When using an F5 load balancer there are 2 predominant ways to setup the network topology. While there are many different names for these methods, in this article I will call them “load balancer on a stick” and in-line. Although the article is about the in-line method, we will quickly review both methods for comparison. […]
