Rebuilding Streams with TShark

Another quick post in a list of CTF techniques: filtering streams with tshark. tshark is the command line half of the packet capture tool Wireshark. The advantage here is it let’s you do all manner of filtering on the command line.


Redis in Rust: Testing redis-cli + GET/SET support

And I’m back. It’s been a busy month with the [Genuary]([Genuary 2023]) series and life in general, but I’m still thinking about Redis in general 😄.

Up this time, let’s see what the official redis-cli app does when talking to our client and actually start handling some commands. Specifically, the very basic commands: SET and GET. With that, we would actually have a (very very basic) keystore up and running!


Redis in Rust: An Echo Server [Part 2]

Following up from Cloning Redis in Rust: RESP [Part 1], we can parse the protocol. So now… let’s do something with it.

The obvious(ish) next step, in my mind? Make a server. It’s all going to be over the network eventually, so it’s either here or storing data. Here it is!

Specifically, my goal is not to build the networking and data structures for this project from scratch. Where there are primitives or libraries that will do something like networking for me, I’m going to use them.


So, how do I write a simple server in Tokio?
