Simple TCP/IP chat server on sockets.
[exec] [addr] [port0] [port1] [-sc]
addris the address of the server to connect toport0is the port for outgoing messagesport1is the port for incoming messages-sopens in server mode-copens in client mode (precedence oversin case of both)
This is just a another hobby project. It doesn't really do much, and the UI is nonexistent. It is also buggy. It may be useful if the usual chat service fails and a replacement is needed.
When the main server process terminates, the process that handles sending global messages back to clients gets stuck in a loop. The main process needs to kill this child process when it exits uncleanly. A server going offline would be no issue, but an interrupted parent process would cause this behaviour if the server remains online.
Due to the way messages are handled, only one client is allowed per IP.
