kandi X-RAY | signalmaster Summary
A simple signaling server for clients to connect and do signaling for WebRTC. Specifically created as a default connection point for SimpleWebRTC.js. It also supports vending STUN/TURN servers with the shared secret mechanism as described in this draft. This mechanism is implemented e.g. by rfc-5766-turn-server or by a patched version of restund.

QUESTION
I am building a master/slave type system in golang. When the slave(called racer) is up, it pings master telling that it is up and ready to receive data and then it starts listening on a port. The port used for pinging and listening are same but I make sure I am closing the connection after pinging. My use case is to use same port for pinging and listening but I get bind: address already in use
error when I use the same port to listen. Sometimes it works sometimes it doesn't. What I am doing wrong?

...ANSWER
Answered 2020-Apr-06 at 01:22Some details vary from one implementation to another, but in general, after closing a TCP connection, the underlying system (host OS, usually) has to keep it around for a little while in case of stray duplicate packets.
This connection, which is in TIME_WAIT state, can block further use of the port, making it impossible to create a new listener, unless you give the right underlying settings to the host OS. Since Go 1.5 or so, Go automatically does this on Linux: see issue 9929. What host OS are you using?
