Stupid question - but are you sure you had an ethernet interface up and 
running on the Redhat9 box when you tried this ?

Getting only localhost back is what you'd expect if there is no active 
ethernet interface, and the /proc/net/arp method would similarly give you 
nothing back.I don't have a copy of Redhat - but I know that back at 
version 6 it supported ifconfig as needed for this method to work.
