A WebSocket to UDP proxy

ws2udp

A WebSocket to UDP proxy.

Installation

Usage:

$ ws2udp
WebSocket to UDP proxy

optional arguments:
  -h, --help           show this help message and exit
  --udp-addr UDP_ADDR  Address of the UDP receiver for broadcasting messages (default=localhost)
  --udp-port UDP_PORT  Port of the UDP receiver (default=57142)
  --addr ADDR          WebSocket address to listen (default=0.0.0.0)
  --port PORT          WebSocket port to listen (default=8765)

The server expects binary messages following the format:

address_length(uint32)address(string)port(uint32)data

• address_length is an integer representing the total length of the address
• address the address where to forward the data as a string (example: localhost)
• port as an integer
• data the original message data

For example, to send the message hello world to localhost:57120, one would send:

b'\x09\x00\x00\x00localhost\x20\xdf\x00\x00hello, world'

The first 4 bytes b'\x09\x00\x00\x00 represents 9, then comes b'localhost' and lastly b'\x20\xdf\x00\x00' for 57120. Whatever comes after this is forwarded.
