The ifreq structure to br_dev_do_ioctl() gives you the interface index (rq->ifr_ifindex) which is currently not being used. May be it can help.. -Kishore >>> David Woodhouse <dwmw2@infradead.org> 05/19/04 10:30PM >>> On Tue, 2004-05-18 at 15:36 -0700, Stephen Hemminger wrote: > Hmm, since all the blue tooth devices have the same address. > Deleting th...

...t will just request to be removed to that membership, decreasing the counter. The code nowadays is fairly close to this : ----- struct packet_mreq mr; [.....] memset(&amp;mr,0,sizeof(mr)); mr.mr_ifindex = ifr.ifr_ifindex; mr.mr_type = PACKET_MR_PROMISC; setsockopt(sock, SOL_PACKET, PACKET_ADD_MEMBERSHIP, (char *)&mr, sizeof(mr)); ----- That would explain why I can''t see it with ip or older ifconfig, any call set by ioctl(SIOCGIFFLAGS) can only bee seen by t...

Hi, I have used bridge-utils 0.9.6 so far in a kernel 2.4.26, uClibc and ppc environment. When I use version 1.0.3 I have the problem that I do not see the brige with the 'brctl show' command if it is not fully set up. It was working with 0.9.6. I tracked the problem down to an 'incompatibility' in bridge/uClibc/kernel. 0.9.6 uses its own if_indextoname function which uses the

Hi, I have a testing multihome setup, with the default gateway being one of the links and using policy routing to honor requests for a specific link. Everything works as expected when I request a specific IP to bind to. But if I request a specific interface things fall apart in ways that I can not explain: default gw (WORKS) ---------- rabbit@Thesaurus:~$ ping -c 1 yahoo.com PING yahoo.com
