Comment 1 Martin Baulig 2012-06-26 20:06:21 UTC
There are two problems in this test:

a) "localhost" may resolve to either IPv4 or IPv6; Windows seem to prefer IPv6.

b) Neither Linux (3.2.0 kernel running Ubuntu) nor Mac OS Lion accept sending to
    UDP port 0 when used with UdpClient.Send().  Windows does.  Using Connect() on
    that port followed by Send() works on Ubuntu, though.

I tested this with a small C program and port 0 is actually invalid on Mac OS.

===
	int sock = socket (PF_INET, SOCK_DGRAM, IPPROTO_UDP);
	printf ("SOCKET: %d\n", sock);

	struct sockaddr_in saddr;
	memset (&saddr, 0, sizeof (saddr));
	saddr.sin_family = PF_INET;
	saddr.sin_port = htons (0);
	saddr.sin_addr.s_addr = inet_addr ("127.0.0.1");
	
	int ret = connect (sock, (struct sockaddr*)&saddr, sizeof (saddr));
	printf ("CONNECT: %d - %s\n", ret, strerror (errno));
=====

I'll change the test to use 127.0.0.1 and port 53.
