I have written a code to send raw data using PF_PACKET to an interface.
Before, on FC4, I was able to see the packets sent using tcpdump.
However, using the same code on Ubuntu , I5.10 cannot capture the
message send. Maybe I have to enable some special options in TCPDUMP?
I have tried on both, wireless and regular ethernet activated
interfaces, but still getting the same results. Please let me know what
do you think.
For what it's worth, use the pcap library for packet capturing,
it's quite portable and easy to use. (and also what tcpdump uses)
.
