rusty-ports

This command line utility allows you to monitor a range of TCP ports on a computer.

This can help reverse-engineering when guessing which port a client will use when connecting to its server.

The program also outputs an escaped version of the messages sent by the clients to help reverse-engineering the protocol.

Setup

cargo build

Usage

./target/release/rusty-ports RANGE_START RANGE_END

Example:

Monitor ports 2000 to 2050 (inclusive).

./target/release/rusty-ports 2000 2050

Note that you can also monitor a unique port by repeating the same value (e.g. rusty-ports 2000 2000).

You need to be root to be able to monitor ports below 1025 (the program will throw an error otherwise).
