What version of Go are you using (go version)?
go version go1.9.2 linux/amd64
What did you do?
Server side, listening on udp ":11110" and print client's src ip and remote ip:
ServerAddr,err := net.ResolveUDPAddr("udp",":11110")
ServerConn, err := net.ListenUDP("udp", ServerAddr)
n,addr,err := ServerConn.ReadFromUDP(buf)
fmt.Println("Received ",string(buf[0:n]), " from ",addr, " to ", ServerConn.LocalAddr())
Client side, two clients send udp to "10.16.83.185:11110" and "127.0.0.1:11110" respectively:
ServerAddr1,err := net.ResolveUDPAddr("udp", "10.16.83.185:11110")
Conn1, err := net.DialUDP("udp", nil, ServerAddr1)
_,err := Conn1.Write(buf)
ServerAddr2,err := net.ResolveUDPAddr("udp", "127.0.0.1:11110")
Conn2, err := net.DialUDP("udp", nil, ServerAddr2)
_,err := Conn2.Write(buf)
What did you expect to see?
Received 1 from 10.16.83.185:51386 to 10.16.83.185:11110
Received 1 from 127.0.0.1:58306 to 127.0.0.1:11110
What did you see instead?
Received 1 from 10.16.83.185:51386 to 0.0.0.0:11110
Received 1 from 127.0.0.1:58306 to 0.0.0.0:11110
It seems net: UDPConn.LocalAddr() would always return "0.0.0.0:11110" instead of "10.16.83.185:11110" or "127.0.0.1:11110".
So is there any way i can achieve the "expect" result?
