What mode should `whois' be?

[Greg Earle]

When I run `whois' as root, everything works fine.  When I run `whois' as
any plain user, I get:

whois: bind: Permission denied

Permissions:
-rwxr-xr-x  1 root     staff       49152 Jan 23  1986 /usr/ucb/whois

Should `whois' be setuid root, or is there some other problem involved?

This is on a Sun-3/160M; Sun OS 3.0.
