# m32chat
m32chat is a simple chat server for the [Morserino](https://www.morserino.info/).

It is a reimplementation of the Python2.7 script [m32_chat_server](https://github.com/sp9wpn/m32_chat_server).

The m32chat service listens on port 7373 for UDP messages and rebroadcasts them to the other subscribed Morserino clients.

To subscribe to the service, just send the message `hi` from your Morserino. The server will respond with `:hi` and the number of clients connected (1 means you're alone).

If a client is inactive for a certain time, it will be removed from the subscriber list. The server then sends the message `:bye` to this client. You can also force the removal by sending the message `:bye`.

Additional notes:
- Periodically, empty UDP packets are being sent to avoid NAT timeouts
- The number of clients is restricted (to avoid abuse)
- Amall delay is introduced (to avoid abuse)
