RES: [Winpcap-users] Mirroring and winpcap

[Gianluca Varenni]

Uhm... stupid question: are you sure you are choosing the right adapter with 
pcap_open (in your l_Device variable)?

Have you tried to use of the samples of WinPcap and see if they work?

Have a nice day

I already change to pcap_open_live and the problem is the same, is
so strange, my program works perfect, the problem persist only when computer
has two active adapters, and second adapter receive a mirror.

Thanx be the same
