I recently figured out what's really going on when "rsh" from a PC-NFS
client says:
	Permission denied
	rcmd: too many open files

The "too many open files" is a red herring: the "Permission denied" is the
real error message.  This user did not have his PC's hostname in his
.rhosts file, and I had recently removed everything from hosts.equiv on
the server, which is why the message suddenly started appearing when it
used to work a week before.

Sun Customer Assistance was able to identify this as a bug in the way that
NFS errors are mapped into PC-DOS errors.  They were very responsive and
helpful, but I had been looking in here for an answer for a while before I
called Sun, without success.  So, I thought I'd post it myself to help the
next innocent victim.
