Configuring different network interfaces

Greetings,

   Had a question regarding the setup of network security for
different cards. I have a Sun Blade 100 running Solaris 9 with up-to-
date patches and an extra network card (Sunswift PCI adapter), and it
is used to run an
instrument. I just jumpstarted it yesterday and got all the patches,
the problem is it now will not communicate with the machine it's
supposed to run. One network card is for the outside world and one
goes to the instrument I'm running. I'm wondering if it is feasible
to alter the security settings so that the card going to the outside
world still has all the security in place, but the card going to the
machine is essentially unencumbered/unprotected and transmitting all
traffic.
   Second is that I have a command that every user should be able to
use by doing an 'su commandname' in a terminal window. It has very
general permissions and is a bit too powerful to leave with no
password on a networked comuputer. Any suggestions about using sudo,
I've been advised that this may be used but am unfamiliar with sudo.
Thanks in advance,

                                                             Chris

P.S. The instrument is a Varian FT-NMR (chemical analysis instrument)
