Unfortunately, SCO can only deal with hostnames no longer than
eight characters. If your hostname is longer, or fully qualified,
you may need to specify your hostname on the
NODename line in /usr/adsm/dsm.sys.
If you use the DISPLAY variable, you will have to supply the
fully qualified host name (i.e.
DISPLAY=host.full.do.main:0 instead of
DISPLAY=host:0).
