I'm compiling for a different kernel than is actually running on the=20 build system, so I had to add a line defining KERNEL_INCLUDE to the=20 Makefile, and I had to add "-I${KERNEL_INCLUDE}" to the CFLAGS=20 definition. Someone might want to do something about that... Anyways, the arp entry issue is still there. The "arp" command gives a= =20 bunch of entries: root@typhoon-base-unit0:/root> arp -n Address HWtype HWaddress Flags Mask Ifac= e 192.168.24.81 ether 00:01:AF:14:E9:8A C bond= 2 172.24.132.2 (incomplete) bond= 0 172.24.136.0 ether 00:C0:8B:07:B3:7E C bond= 0 172.24.137.0 (incomplete) bond= 0 172.24.0.9 ether 00:07:E9:41:4B:B4 C bond= 0 10.41.18.101 ether 00:0E:0C:5E:95:BD C eth6 172.24.0.11 ether 00:03:CC:51:06:5E C bond= 0 172.24.132.1 ether 00:01:AF:14:E9:88 C bond= 0 172.24.0.15 ether 00:0E:0C:85:FD:D2 C bond= 0 172.24.0.3 ether 00:01:AF:14:C8:CC C bond= 0 172.24.0.5 ether 00:01:AF:15:E0:6A C bond= 0 The original "ip" command and the new one ("/tmp/ip") both give the sam= e=20 results--some of the entries are missing. root@typhoon-base-unit0:/root> ip neigh show all 172.24.137.0 dev bond0 FAILED 172.24.0.9 dev bond0 lladdr 00:07:e9:41:4b:b4 REACHABLE 10.41.18.101 dev eth6 lladdr 00:0e:0c:5e:95:bd REACHABLE 172.24.0.11 dev bond0 lladdr 00:03:cc:51:06:5e STALE 172.24.132.1 dev bond0 lladdr 00:01:af:14:e9:88 REACHABLE 172.24.0.15 dev bond0 lladdr 00:0e:0c:85:fd:d2 STALE 172.24.0.3 dev bond0 lladdr 00:01:af:14:c8:cc REACHABLE 172.24.0.5 dev bond0 lladdr 00:01:af:15:e0:6a STALE root@typhoon-base-unit0:/root> /tmp/ip neigh show all 172.24.137.0 dev bond0 FAILED 172.24.0.9 dev bond0 lladdr 00:07:e9:41:4b:b4 REACHABLE 10.41.18.101 dev eth6 lladdr 00:0e:0c:5e:95:bd REACHABLE 172.24.0.11 dev bond0 lladdr 00:03:cc:51:06:5e STALE 172.24.132.1 dev bond0 lladdr 00:01:af:14:e9:88 REACHABLE 172.24.0.15 dev bond0 lladdr 00:0e:0c:85:fd:d2 STALE 172.24.0.3 dev bond0 lladdr 00:01:af:14:c8:cc REACHABLE 172.24.0.5 dev bond0 lladdr 00:01:af:15:e0:6a STALE However, if I specifically try to print out one of the missing entries,= =20 it shows up: root@typhoon-base-unit0:/root> /tmp/ip neigh show 192.168.24.81 192.168.24.81 dev bond2 lladdr 00:01:af:14:e9:8a REACHABLE Chris
