What's This?
The packet inspector is a Minecraft proxy for viewing the contents of packets as they are sent/received. It uses Valence's protocol facilities to display 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
Firstly, we should have a server running that we're going to be proxying/inspecting.
cargo r -r --example conway
Next up, we need to run the proxy server, this can be done in 2 different ways,
either using the GUI application (default) or by using the cli feature gate.
To launch in a Gui environment, simply run packet_inspector.
cargo r -r -p packet_inspector
To Launch in a Cli environment, build packet_inspector with the default
features disabled, and supplying the cli feature. note that you must
supply the listener and server addresses as arguments.
cargo r -r -p packet_inspector --no-default-features --features cli -- 127.0.0.1:25566 127.0.0.1:25565
To assist, --help will produce the following:
A simple Minecraft proxy for inspecting packets.
Usage: packet_inspector <LISTENER_ADDR> <SERVER_ADDR>
Arguments:
<LISTENER_ADDR> The socket address to listen for connections on. This is the address clients should connect to
<SERVER_ADDR> The socket address the proxy will connect to. This is the address of the server
The client can now connect to localhost:25566. You should see the packets in
stdout when running in cli mode, or you should see packets streaming in on the
Gui.
Quick start with Vanilla Server via Docker
Start the server
docker run -e EULA=TRUE -e ONLINE_MODE=false -d -p 25565:25565 --name mc itzg/minecraft-server
View server logs
docker logs -f mc
Server Rcon
docker exec -i mc rcon-cli
In a separate terminal, start the packet inspector.
cargo r -r -p packet_inspector --no-default-features --features cli -- 127.0.0.1:25566 127.0.0.1:25565
Open Minecraft and connect to localhost:25566.
Clean up
docker stop mc
docker rm mc
