Related, I have loved using toxiproxy for testing latency with my services. Tools like this are great for uncovering subtle bugs and helping to learn more about how various transports / protocols handle things. I successfully used toxiproxy to simulate an end user problem with a websocket based tool and I don't know how I would have done it otherwise.

Starred. This is going to be useful in building resilient backends, thanks for sharing.

I imagine this could be a network extension in macOS for example, so that it can be applied to the full system without configuration.

Thanks for the link, it’s very interesting!

Go is a great tool for simulating network concepts, I've done it too.

Learning this at uni this semester. This looks super cool, thanks!

You might want to .gitignore the binaries btw.

What kind of course is that and what exactly are you learning to do?
