ChatGPT your Project Docs
I mentioned in my last post that I would start updating practical use cases for generative AI. The first example use case is your project documentation. As software engineers, we spend days of our lives writing project docs. The reality is that people learn and consume data differently. Overly detailed docs may cause some people’s eyes to glaze over while …
Open Source Flow Monitoring and Visualization
At the heart of any reasonably sized network, should be a solid strategy around flow collection, querying and visualization. Proper use of flow logs are crucial to SecOps/NetOps from triaging attacks to capacity planning and traffic trending. I remember some 20 years ago, the first time I saw flow logs being visualized in rrdtools it was pretty close to magic. …
Measuring Network Bandwidth using Iperf and Docker
At the heart of any network engineer’s toolkit, are applications that let you peer into the network for performance, congestion and capacity planning. One of the thoroughbreds in the open source network tools collection is iperf. Iperf has been around for a long time. The good folks at ESnet updated the original iperf with new features and what not and …
GoBGP – A Control Plane Evolving Software Networking
If I have talked to you over the past year or two about networking, odds are I have mentioned a project to you called GoBGP. If we have spoken a lot, you are probably sick of me talking to you about GoBGP 🙂 There is a reason, it’s because GoBGP is a missing link in networking that has been for …
Configuring Macvlan and Ipvlan Linux Networking
Macvlan and Ipvlan are both Linux type networking interfaces that are both supported by the Linux kernel. They are unique for a few different reasons. One thing that makes them both very attractive is they do not use bridges in their implementation and natively namespace aware. It solves some painful problems such as getting access to a gateway from a …
Docker on Google Compute Engine Using Docker Machine
Next up in Using Docker Machine across private and public clouds, is Google Compute Engine (GCE). As with the other posts, a diagram of how I view the importance of a Docker Machine abstraction. First, if you don’t already have an account you can get $300 credit expiring after 60-days towards Google GCE that we will use as Docker hosts …
Building Network Tools using Docker
I am going to start pushing out an app every month that fixes some problem in networking. In this case I hacked it up over the past couple of weekends, but other times it will just be me using someones open source awesomeness and demoing it. First some thoughts on where we are in the wild world of networking to …
Running Docker Machine on Digital Ocean
Continuing the series on cloud provider examples using Docker machine, up next is Digital Ocean. As with the other posts here is a diagram of how I view Docker Machine usage. For those who don’t have an account already, you can sign get $10 credit with the following link. When you sign up it requires a credit card that won’t …
