Comments

The semantics of the test is to send a DNS query over UDP to a non existent server, and this will generate a PortUnreachable exception. But the generation of an ICMP destination unreachable is not an absolute, as per the RFC "If, in the destination host, the IP module cannot deliver the datagram because the indicated protocol module or process port is not active, the destination host **may** send a destination unreachable message to the source host." It is possible that, as has been seen with other UDP based test scenario on this particular host, the kernel doesn’t generate the ICMP dest unreachable, and just drops the datagram. I have a UDP joke ... But you might not get it !!

Does this happen if it is not a loopback address? Yes, I have run the test using localHost instead of loopback and it is consistent failure on this host. Could it be a firewall configuration or some other security setting that disables ICMP DST Unreachable? There are a number of DOS attacks associated with ICMP. I’ve looked through the kernel parameters, and only see net.inet.icmp.drop_redirect: 1 But this should have no influence on icmp dst unreachable ! Maybe there is a conversation to be had with Apple support on this
