/usr/sbin/snoop on my Solaris systems -- but it might be elsewhere on an
older system, and it's not installed by default.

Alternative is tcpdump, which uses a library called libpcap. The home page
for both is or , and they can be
downloaded from You'll need a decent C compiler --
which probably means gcc, as Sun stopped providing a compiler with the OS a
long time ago.

On most of the Ethernet-enabled printers I've come across (mostly HPs,
Lexmarks, and Xeroxes) you can do the setup from the front panel --
sometimes tedious, but usually not too hard to understand.

A reasonable assumption. Have you tried printing out status pages?
 Sometimes that will show you things like IP address, protocols enabled,
that sort of thing. Usually you can do it by holding down one of the
buttons when you turn the power on.
