Right.  Thanks.  That's even more direct than dumping the ARP cache.

I like this, a lot.  It's the "You _will_ use the IP address I've
configured you to use, even if the most common sorts of mishaps occur"
approach.  Cheap insurance.

You don't actually need those:  Assigning the long-term static IP via the
front-panel switches is a little tedious but not difficult, and then you
just telnet in and configure other printer functions via a
self-explanatory clear BBS-like text menu interface.  No need for a
private network or HP JetAdmin for Win32 or any of the other OSes.

Excellent point.

It's been so long since I needed BOOTP that I'd forgotten entirely about
that.  But yeah, BOOTP's pretty much gone with the dodos and early Sun
SPARC boxes, and should be disabled unless you actually need it.

I used to have a commented /etc/dhcpd.conf example file from my "kitchen
network" we used for CABAL meetings at my older house, 2033 Sharon Road
-- but I suspect it got blown away.
