SOCK_RAW sockets and IPPROTO_AH

[Sebastien Petit]

Hi,

Is there a way to receive AH packets in userland with a SOCK_RAW socket ?
ie: socket(AF_INET, SOCK_RAW, IPPROTO_AH) ?
I found that this socket call doesn't work under FreeBSD. On OpenBSD, it works but a recvfrom/read doesn't return any AH packets when it was received on an interface.

Is there another proper way to receive AH packets in Userland under FreeBSD ? (bpf/pcap is not a solution because I want to have a socket opened for multicast join)

Any help will be appreciated.

Regards,
Sebastien.
