--- Comment #3 from Iskren Todorov metalgrid@mail.bg 2013-03-26 07:48:51 CDT --- I can't find the edit button, I just sniffed the traffic and it seems that wine substitutes the 0.0.0.0 with the loopback address 127.0.0.1, so I'm simply pinging myself. Here's the tcpdump output: tcpdump -i lo icmp -n tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on lo, link-type EN10MB (Ethernet), capture size 65535 bytes 14:48:09.401500 IP 127.0.0.1 > 127.0.0.1: ICMP echo request, id 21554, seq 256, length 40 14:48:09.401535 IP 127.0.0.1 > 127.0.0.1: ICMP echo reply, id 21554, seq 256, length 40
