[Winpcap-users] Filtering for DNS

[Prashant Kasal]

Hi All,

I'm trying to filter the network packets to get DNS information

pcap_compile( adhandle, &fcode, "dns", 1, netmask), but when I executed this
line I'm getting the return value < 0;

does anybody know how to filter the network packets for DNS?

Any help would greatly appricated.
