got this in the security check yesterday:
> arplookup 127.0.0.1 failed: could not allocate llinfo
> arpresolve: can't allocate llinfo for 127.0.0.1rt

Questions:
1) What is the "rt" thing on the end of 127.0.0.1;
2) How can I find out which interface the packet (possibly ARP, because
I filter out spoofed packets on all interfaces and I got no messages
from ipmon)

The machine has two Ethernet interfaces, rl0 (Realtek 8139A), and ed0
(Realtek 8029A).

Thanks a lot,
        Alex
