how to find port used for listen (typically next available) #28

Closed sdetweil closed 7 years ago

sdetweil commented 7 years ago

I have this existing protocol, where I

setup a tcp/ip listen (any port, next available, don't want to hard code)
get the port for the listen
send a UDP broadcast to a custom server, with the port number in the message data
the server parses the message, gets the port number
server opens socket back to client (listen),
server sends message containing server address.

I am using the udp and tcp plugins.. chrome.sockets.tcp.onReceive.addListener(recvListener);
sendTo(MirrorRequest+ip, ReceiverPort, BROADCAST_ADDR);

need to use the tcpCPServer plugin for that process
