I am familiar with the problem he explained.  We have the same problem.  It is
not a matter of changing the kernel variable "nobody".  I have done this on
two VAXes both running ULTRIX 2.2; It works on one, but not the other.  In my
case, the uVAX II server works fine while my VAX 3500 doesn't.

	DEC...IF YOU ARE LISTENING...PLEASE HELP!

I am anxiously reviewing this newsgroup for someone to relay a fix.

BTW, you can also change this "nobody" variable on a currently running system
with:
	adb -k -w /vmunix /dev/mem
	nobody?W 0
	^D
This will make root access over NFS allowable immediately.
