However when I integrate that same code with nfnetlink_queue code it no longer works as expected (i.e. it returns successfully (0) whether or not the address was found in the arp cache and it doesn't copy the mac address into the struct arpreq). I searched the archives and didn't see anything about this. Does anyone have any idea what could be causing this? I'm running ... # uname -a Linux bugsbunny 2.6.30.9-102.fc11.i686.PAE #1 SMP Fri Dec 4 00:19:26 EST 2009 i686 i686 i386 GNU/Linux ... and these two modules get loaded when the nfnetlink_queue code gets initialized ... # /sbin/lsmod Module Size Used by nfnetlink_queue 7548 1 nfnetlink 3760 2 nfnetlink_queue Thanks
