From: Jeff Garzik <jgarzik@mandrakesoft.com> Date: Wed, 13 Feb 2002 03:33:41 -0500 When I boot into 2.2 MDK or custom kernel, SIOCGIFFLAGS indicates IFF_PROMISC when tcpdump is running. When I boot into 2.4 MDK or custom kernel, SIOCGIFFLAGS does not indicate IFF_PROMISC under the same conditions. Jeff, please, go into v2.2/linux/net/packet/af_packet.c and read the comment above CONFIG_PACKET_MULTICAST and the code that macro's definition controls. In particular, read the commentary about multicast routing daemons. Something is different, perhaps your kernel is configured differently or something else, but something is different as the code is identical. - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
