[Winpcap-users] missing usb adsl connection

[Gianluca Varenni]

This is the expected behavior. Dialup connections show up only when the connections are established. If you need to capture from the connection handshake on, you need to use the device called "Adapter for generic dialup and VPN capture".

Have a nice day

    No, I meant the text output of the sample application.

    There are few samples in the guide following WinPcap. Can you please be specific?

    Also, can you please tell me  what is the output of windump -D (capital D)? windump is available at www.winpcap.org/windump

    Here is the output(the one I need  is WAN (PPP/SLIP) Interface, and it shows up only when USB modem is connected. The "for" loop that I attached runs just one cycle and doesn't reveal both, the first and the second devices)-

    1.\Device\NPF_GenericDialupAdapter (Adapter for generic dialup and VPN capture)
    2.\Device\NPF_{3A5DC188-23D6-4FAB-A174-25BEE837D61F} (WAN (PPP/SLIP) Interface)
    3.\Device\NPF_{623BC411-0BB9-4538-888B-F002A4F3DD0F} (Realtek RTL8139 Family Fast Ethernet Adapter (Microsoft's Packet Scheduler) )

    Thanks

      Dear Sir,
      Please follow my answers...


        What does the sample application return?

        The function pcap_findalldevs_ex returns ZERO ( I hope that's what you asked for).

        Are you running on Vista?

        The OS is XP SP2.

        Thanks

          Hi all,
          I usually use my NAT router for communication and Winpcap works fine.
          Trying to connect with usb adsl modem fails since the following code doen't see it - it sees just the Ethernet adapter.  I tryed with Ethereal and I could sniff the modem easily. This code is taken from the examples following the product.
          Can someone help please
          Thanks
          I. lesher

              /* Retrieve the device list on the local machine */
              if (pcap_findalldevs_ex(PCAP_SRC_IF_STRING, NULL, &alldevs, errbuf) == -1)
              {
                  fprintf(stderr,"Error in pcap_findalldevs: %s\n", errbuf);
                  exit(1);
              }
              
              /* Print the list */
              for(d=alldevs; d; d=d->next)
              {
                  printf("%d. %s", ++i, d->name);
                  if (d->description)
                      printf(" (%s)\n", d->description);
                  else
                      printf(" (No description available)\n");
              }
