Subject: dev_add_pack() question
Date: Wed, 9 May 2001 14:29:06 +0000 [thread overview]
Message-ID: <20010509142906.B1388@lda.sur5.net> (raw)
Hello,
I register a callback function with dev_add_pack() this way:
memset (&proto, 0, sizeof proto);
proto.type = htons (ETH_P_ALL);
proto.func = my_callback_function;
dev_add_pack (&proto);
my_callback_function() receives all packets with local src/dst IP (including
SNATed ones) as well as all incoming ones, but forwarded outgoing packets are
not passed to my_callback_function(). Looks like AF_PACKET sockets also rely
on dev_add_pack(), yet of course tcpdump (correctly) shows all the packets.
How should I register a callback with dev_add_pack() so that the callback
receives all the packets ?
Save yourself,
Nergal
