What's This?

The packet inspector is a very simple Minecraft proxy for viewing the contents of packets as they are sent/received. It uses Valence's protocol facilities to print packet contents. This was made for three purposes:

• Check that packets between Valence and client are matching your expectations.
• Check that packets between vanilla server and client are parsed correctly by Valence.
• Understand how the protocol works between the vanilla server and client.

Usage

First, start a server

cargo r -r --example conway

In a separate terminal, start the packet inspector.

cargo r -r -p packet_inspector -- 127.0.0.1:25566 127.0.0.1:25565

The client must connect to localhost:25566. You should see the packets in stdout.

If you only want to see errors, direct stderr elsewhere.

cargo r -r -p packet_inspector -- 127.0.0.1:25566 127.0.0.1:25565 > log.txt
