Read(rsp) ? isnt that just an empty variable? 
                  
                  
                  
                  
                  
                    rsp := make([]byte, 48)
                  
                  
                    conn, err := net.DialUDP("udp", nil, raddr)
                  
                  
                  
                  
                  
                  
                  
                  
                    read, err := conn.Read(rsp)
                  
                  
                
rsp contains actual bytes read from the connection. read is number of bytes actually read
