A horrible name for a Rust version of Socky, a simple tool to listen on TCP sockets to observe connection attempts to servers on the local host.
This is designed to provide some level of visibility into any activities on your system where local servers running on Well-Known (and merely well-known, if you catch my drift) ports are being enumerated.
I would like to be notified when web pages think this behaviour is justified.
Inspired by the proof of concept of this demonstrated by https://wybiral.github.io/wtf/
I do not yet know how to write good Rust code. This is experimental and not for production use. It may cause harm. It may be a Bad Idea. You have been warned.
cargo build -r
The executable is built in target/release/corroded_sock.
For example, to listen on the Steam port, 27060:
./corroded_sock 27060
For systemd systems, you can make this start upon login as follows.
Copy systemd/listen-steam-port.example.service to ~/.config/systemd/user/listen-steam-port.service.
Alter the ExecStart line to point to where the corroded_sock executable is held.
Enable the service:
systemctl --user enable --now listen-steam-port.service
Test that you receive a desktop notification:
nc 127.0.0.1 27060
