Description Iskren Todorov 2013-03-25 12:54:31 UTC

Greetings. Slackware64-current with wine-1.5.26, wineserver and wine-preloader are  with capabilities of opening raw sockets (setcap cap_net_raw+ep /usr/bin/wineserver; setcap cap_net_raw+ep /usr/bin/wine-preloader). Pinging a random IP address or website with a ping tool (Like the free Colasoft Ping Tool) works as it should, but pinging 0.0.0.0 returns 0ms ping responses, while it should return timeouts. If you need any logfiles or traces, tell me so I can dump them and provide them. Thanks.

Are you using IcmpSendEcho?

Comment 2 Iskren Todorov 2013-03-26 07:37:44 UTC

I don't know if the program (Colasoft Ping Tool) is, but I tested the following:
Compile the example program from http://msdn.microsoft.com/en-us/library/windows/desktop/aa366050(v=vs.85).aspx with
wineg++ -m32 icmpsendecho.cpp -lws2_32 -liphlpapi 
and ran the resulting executable

./icmpsendecho.exe 0.0.0.0
        Sent icmp message to 0.0.0.0
        Received 1 icmp message response
        Information from this response:
          Received from 127.0.0.1
          Status = 0
          Roundtrip time = 0 milliseconds

I hope this info is useful.

Comment 3 Iskren Todorov 2013-03-26 07:48:51 UTC

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

If you use the ping utility in Windows the address 0.0.0.0 returns an invalid address.
If you use the ping utility in Linux the address is converted in 127.0.0.1 as you stated.
