ser2net2ser

Motivation

I've been using socat + ser2net for sharing serial devices over network for some time, mainly in my other project kubeserial. I've run into few limitations so I created this project to recreate the behaviour of socat + ser2net and then solve connection issues I've been having.

Requirements

• Linux or macOS operating system
• CMake for building the project
• Docker (optional) for containerization

Building the Project

Clone the repository and use CMake to build the project:

git clone https://github.com/janekbaraniewski/ser2net2ser.git
cd ser2net2ser
make build

This will compile both the server and client applications.

Running the Server

The server needs to be connected to a serial device. It can be started with the following command:

ser2net2ser serve \
  --device /dev/ttyUSB0 \
  --baud 9600 \
  --port 12345

--device: Specifies the serial device.
--baud: Sets the baud rate for the serial device.
--port: TCP port on which the server will listen for incoming connections.

Running the Client

The client should be run on the machine where you want the virtual serial port to be created:

ser2net2ser connect \
  --server 192.168.1.100 \
  --port 12345 \
  --vsp "tty.usbserial-666"

--server: IP address of the server.
--port: TCP port on which the server is running.
--vsp: Name of the virtual serial port to be created.

Docker Containers

Dockerfiles for both the server and client are included. Build and run the containers using:

make build-images
