Question Problem sniffing with raw socket

Hi every body!!

I am working in a kind of sniffer for bandwidth calculating. I am using raw sockets this way:

fd = socket ( PF_INET, SOCK_RAW, IPPROTO_TCP );

and reading with "read" function. I have put the interface into promiscuous mode with "ioctl" too. And everything looks fine, but I can't capture packets generated locally. Every packet sent by my PC is not sniffered.

Did you know what could be hapening??

Thanks in advance,

I have tried this way but it still capture only the incoming packets. I think it could be possible to capture all the local traffic without using libpcap.

Please, if somebody knows what could be happening, tell me, ok?
