snet is a small tool that connects to a serialport and then forwards everything it collects from there to tcp sockets, the main difference to ser2net is that this allows multiple accesses in both directions, and that this does a lot less and is less mature :)

Its unsecure so only run on trusted networks on non-critical things, its just a raw connection to the serialport, meaning every byte is forwarded in both directions. Telnet works as a client for simple things such as watching the output

I might write a client that emulates a serialport on the client side...

Install and run

First install it using cargo install, or go clone the repo and use cargo build

Cargo install:

cargo install snet
~/.cargo/bin/snet -s /dev/ttyUSB0 -p 1234


git clone https://github.com/TotalKrill/snet.git
cargo run --release -- -s /dev/ttyUSB0 -p 1234


There should now be a tcp port that you can connect to:

telnet 1234


We had a pool of raspberry pi that was running gdb servers and had a lot of printf-debugging going on, this meant we had ssh access and tmux sessions etc on the raspberries for everyone who wanted to try something. It got tedious.
