Are most of your clients going to be windows machines? if so, you
should thing seriously about using samba.
This is my private network and I've used samba previously; I'm just
trying to learn how to configure NFS. I'll go back to samba if I
can't figure this out.
( you should also read http://www.openbsd.org/mail.html and include
all even vaguely related config files and output of things like dmesg
and nfsstat )
I've googled quite a bit on this as well as searched MARC. I don't
know any other files to include other than /etc/exports.

i notice you're using 'david:guest' here... the first question
springs to mind is to verify that user david is in group guest?

Please provide specifics? do you mean with the david:guest uid:gid
mentioned above?
Yes. When I map the drive through Explorer, it prompts me to confirm
the uid:gid I am connecting with (1000:31) or to select a different
one.

what user:group are the parent directory? david:guest, or something
like david:david ? what permissions are they?
[EMAIL PROTECTED] ls -ld /home/david

What do the log files on the server say?
Absolutely nothing. I can mount, read, try to write, and unmount all
without generating a single log message in
/var/log/{messages,daemon,secure}. I'll try running portmap and
mountd in debug mode tomorrow and see if anything jumps out at me.

man mountd
( http://www.openbsd.org/cgi-bin/man.cgi?
query=mountd&apropos=0&sektion=0&manpath=OpenBSD
+Current&arch=i386&format=html )
will answer this for you
The man page says to read the RFCs; the RFCs say to ask the
portmapper; this confirms my original guess of "don't bet on it".
