Hi, it seems that ipconfig has a problem if multiple devices are up and connected to the same network. It seems that it uses the wrong socket/device index to compare it to incoming packet. To be more precise, the packet gets discarded in do_pkt_recv as the ifindex from state differs always from the incoming packet To reproduce create two tap devices: $ sudo tunctl -u uli -t tap0 Set 'tap0' persistent and owned by uid 1000 $ sudo tunctl -u uli -t tap1 Set 'tap...

This patch fixes a bug on systems with multiple connected network devices. As packet_peek uses all devices to receive data instead of a specific device. As the return value was never reset it was possible that packets from other devices were returned by packet_peek. That means that the ifindex did not match any ifindex of the specified devices the packet was never removed and packets for the correct device were never processed. This patch enhance packet_peek and packet_discard to only work on packages for the specified device instead of all packets. Signed-off-by: Ulrich Dangel <uli...

Essentially identical to v1 except that it now uses (overloads?) the --mac option to supply this data. Rich.

Hello I have serious problem with zhone z-plex 10 the device sometimes get red alarm on some channel and then the device suddenly shutdown. I try to unplugged the power chord and plug again, but the device still didn't up. I have to wait for long time to get this device up again. How can i fix this problem, so i can get this device immediately? Eris Riswanto

Hi Is there a way to either: Find the real ifindex/ifname a mac-address is bound to or Find the real ifindex/ifname of an incoming packet ? I am writing a dhcp server and need to know what real interface the dhcp re= quest packet came from. An acceptable solution would be to get the interfac= e by the mac-address, but that can be faked so I would...
