Hi, for the nth time I send this email, hoping that majordomo won't eat it again.
I know this has been extensibly discussed circa 2001, but I found that there's still problems: in debian (at least) neither ifconfig nor ip can tell that the interface is in promiscuous mode. I know about the deprecation of IFF_PROMISC, but I couldn't find out which is the current way of knowing the real state of the interface. I want to fix ifconfig, so this is not an issue of PACKET_(ADD|REMOVE)_MEMBERSHIP, I need to query the real device state. Also, it's unclear to me what happens when you set/reset IFF_PROMISC and then libpcap fiddles with membership. Is this documented somewhere? It has been said many times that ip should give this information. I cannot see this: $ sudo tcpdump -ni eth2 port 3333 & $ dmesg |tail -2 device eth2 entered promiscuous mode audit(1175904782.767:40): dev=eth2 prom=256 old_prom=0 auid=4294967295 $ ip link show eth2 4: eth2: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qdisc pfifo_fast qlen 1000 link/ether 00:18:de:81:24:a2 brd ff:ff:ff:ff:ff:ff $ ip -V ip utility, iproute2-ss060323 I think that is a problem for user tools to not know about this, and I want to fix them. I don't know how. Can anyone give me a pointer?
