[SOLVED] UDP port question...?Posted: Tue Oct 14, 2008 10:34 pm

I am sending out udp packets at port 1900. I am using a packet sniffer to monitor the actual network activity. The information from the packet sniffer shows that the UDP packets are sent out a random ports in the 50000s and it goes to the correct ip address and port.

 

My question is... How can you find out what port the udp packets were sent on?

 

Here is the basic code:

 

$Socket = socket_create(AF_INET,SOCK_DGRAM,SOL_UDP);
socket_set_option($Socket,SOL_SOCKET, SO_REUSEADDR, 1);
socket_bind($Socket,$IP_Address,$Port);
socket_sendto($Socket,$soap_out,strlen($soap_out),0,$IP_Address,1900);

socket_getsockname($Socket, $IP, $PORT);

 

$PORT does have the correct port that the udp packet is being sent on.
