[Kaboodle-devel] Sniffer

Hello, Scott >Igor: >So just to confirm...the LAN detection process checks >all interfaces now, and it now keeps track of which class-C ranges >are the "active ranges"? Please let me know if/when these changes >are in the CVS server. Yes, LAN detection process checks all interfaces now. It pings it's own class-C ranges on start-up. And it is supposed to ping all newly sniffed class-C ranges on StartPing(PING_ON_NEW_DEVICE_DISCOVERY). The problem is that the sniffer would work at all. I wonder if anybody has ever seen it work? I found some info on the pcap lib used in the CSnifferThread class: http://www.vspu.ac.ru/en/man2html?pcap?3 It says: pcap_lookupdev() returns a pointer to a network device suitable for use with pcap_open_live() and pcap_lookupnet(). Which should be understood only as returns a pointer to only ONE (active) network device, not array. In file snifferthread.cpp there is a function CreateAdapterNameList which treats it as a null-separated chain of names.   temp = (WCHAR *)device;   while (*temp != 0 )   {     wcscpy((WCHAR *)adapterName, temp);     temp += wcslen(temp);     temp++;     m_iAdapterNum++;   } Is that right? I would not mind this if it had worked. But I tested it on two machines (2000 and W98) and in both cases I had m_iAdapterNum == 0. Later on, if I force the SnifferThreadFunction to be called, it makes a call to pcap_t* devHandle = p_pcap_open_live(device,BUFSIZ,1,0,errbuf); and errbuf contains the following error text: "Error opening adapter. The system cannot find the file specified". -Igor
