WARNING! Ultrix 3.x changed return values!

I just spent some time working on a problem that cropped
up because DEC (in their Ultimate wisdom) changed return values
on the ruserok() call (see rcmd(3x) for details). 

Since I spent time on it, I thought I'd best pass this on
to the newsgroup and (hopefully) save someone else the
time.

Under Ultrix 2.x (and under 4.2 BSD and 4.3 BSD),
the ruserok() routine returns as follows:

	A 0 is returned if the machine name is listed in the
	"hosts.equiv" file, or the host and remote user name
	are found in the ".rhosts" file.  Otherwise ruserok
	returns -1.

Under Ultrix 3.x, the ruserok() returns as follows:

	A 1 is returned if the machine name is listed in the
	"hosts.equiv" file, or the host and remote user name
	are found in the ".rhosts" file.  Otherwise ruserok
	returns -1.

Yes, kids, they changed it from 0 (zero) to 1 (one) if everything
is OK.

Anyway, I found this very rude!
