...I bind the user space socket to guarantee that it will receive the ETH_P_802_2 frames received/posted by eth0. It looks to me like: if the socket is created and then bound to eth0 it will never see any frames of type ETH_P_802_2 when a bridge is place. Is this correct? What should happen when the PF_PACKET socket is bound to br0? Should I expect to see 802.2 packets from the bridge? Will all the packets pass by undetected? Will the bridge only pass the packets up if an IP address is assigned to br0? Another question, again w/o ebtables.... Is there a way with PF_PACKET to intercept a certain proto...

Hi everyone, Can anybody help me to find some example about PF_PACKET and Raw Socket programming to receive at one MAC address and send the same packets to the second MAC address? I appreciate your help and I’m looking forward to receive a reply. Regards, Al-Gharribeh _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http:/...

Ahoy, I've encountered some confusing semantics with using PACKET(7) sockets on bridge-enslaved interfaces. Specifically, if my socket accepts all types of frame (bind() to ETH_P_ALL) then it gets all packets; but if it accepts any specific type (e.g. ETH_P_IP), then it receives no packets at all. That is how it's coded in net/core/dev.c's netif_receive_skb(). First ETH_P_ALL

Hello, I've got a very strange problem. Lately I've been setting up my linux servers for network (layer2) redundancy with a bridge interface containing two ethernet interfaces connecting to two switches. So far I didn't have any problems with it, but now a very strange thing happens with a new server I'm installing. The server is an ibm x346 having two onboard BCM5721 cards, the

as the next klibc release 1.5.16 looks like shaping up, I have a trouble to build that for Debian. currently I build depent on linux-libc-dev, I don't know what against I can build latest klibc, see klibc fails to build due too: make -C linux/ ARCH=x86_64 INSTALL_HDR_PATH=debian/tmp/usr/lib/klibc/ headers_install make[3]: *** No rule to make target `headers_install'.
