[I'm only on "hackers" and "security", so please reply to me
directly.]

Can someone tell me why this happens:

# tcpdump -e -f -l -n broadcast or icmp or arp or rarp
...stuff..

<in another window>
# arp -s 206.170.75.90 0:0:c0:58:b9:c7 pub

<back in the tcpdump window>
00:01:10.865938 0:0:c0:58:b9:c7 ff:ff:ff:ff:ff:ff 0806 42: arp who-has 206.170.75.90 tell 206.170.75.90

Is this bogus, or a subtlety of the arp protocol I don't understand? 

BTW, the machine does not properly respond to arp requests, but
I can't see the router to tell if there's something bogonic in the
arp cache.

Treat people as if they are what they ought to be, and you help them to 
become what they are capable of being.
