I'm trying to run a reflector on my ISP but keep getting,

CU-SeeMe (tm) Reflector version 4.00B3
Copyright (C) 1993, 1994, 1995, Cornell University
See README.reflector.4.00B3.txt for notices, permissions and restrictions
if_getlist: ioctl(SIOCGIFCONF) : Invalid argument: FATAL ERROR: EXITING

I'm running on the sun version on a
UNIX(r) System V Release 4.0

Can anyone give me some clue from this what might be wrong?
