Hi,
is it possible to capture Tx packets on an ethernet interface using
pcap_inject or pcap_sendpacket ? I've used pcap_dispatch succesfully
to capture Rx packets coming on the wire, but I have not been able to
send packets out using the above two libpcap function. So I see no
packets coming out of the SUT or packets coming in at the destination
system (using e.g. tcpdump or another sniffer). Has anyone been able
to use pcap_inject succesfully? If yes, could you share your kernel
config?
I have both PF_PACKET and PF_PACKET_MMAP enabled in my kernel
(2.6.32.3). The ethernet interface is not using bonding.
My question is basically the same question as this older post:
http://www.mail-archive.com/kernelnewbies@xxxxxxxxxxxx/msg08280.html
(The poster of this thread claims that bonded interface behaviour is
fine when sending packets. I have not experimented with bonding
interfaces)
thanks for any suggestions,
- Vasilis
