|
|
While working on a project we tried to reduce analysis complexity coming from ’noise’ in the network traffic recorded to a central INetSim cluster we were running.
|
|
We decided to decentralize the internet simulation, put it into a container image and run directly on every host multiple times in virtual networks.
|
|
Unfortunately INetSim has a relatively huge memory footprint (~1GB) which alone wouldn’t been a showstopper but in combination with a relatively long startup time I felt having something smaller could be beneficial so I started to implement a prototype in Go.</p><p>2 years later INetMock has grown to kind of a full router (supporting DNS and DHCP) with support for faking HTTP/s (direct or proxy requests) requests.
|
|
Furthermore it is able to record PCAP files for further analysis and it emits events for every handled request.</p><p>It comes with a descriptive configuration language (embedded in a YAML configuration) to setup the behavior of all components and to define health checks/integration tests to validate your configuration.</p><p>Apart from working as a router it can also be used e.g. for integration tests of HTTP APIs, DNS/DoT/DoH clients and most likely other things I haven’t even thought about.</p><h2 id=goveal>Goveal

|
|
Originally I used GitPitch but then the author decided to go with a commercial license.
|
|
The commercial license made sense when I was working at the university but after that it didn’t really make sense any more.
|
|
So I decided to replace it with a small custom CLI rendering the markdown into a static HTML file and serving it as a local web server (basically).</p><p>Later on I refined it more and more.
|
|
Currently I’m working on a rewrite which adds e.g. 1st class support for <a href=https://mermaid-js.github.io>mermaid-js</a> diagrams in slides.</p></div><div class=post-info><a class="post-hidden-url u-url" href=https://www.1533b4dc0.de/projects/>https://www.1533b4dc0.de/projects/</a>
