Re: Troubleshooting NFS/SFU

I've tried to configure NFS and am nearly all the way there, but it
seems like I've hit a pretty big stumbling block.  I've got OpenBSD
4.1-stable (10.0.0.1) with an NFS export of my home directory.  I also
have a Windows XP machine (10.0.0.2) and installed the SFU 3.5 NFS
client.

[/etc/exports]
/home/david -mapall=david:guest -network=10.0.0.0 -mask=255.255.255.0

I can successfully mount this share locally and perform both reads and writes.

Without any of SFU's User Name Mapping configured, I can mount the
share with uid/gid of -2/-2 as advertised.  Appropriately, I cannot
access any files or directories that are not world-readable.  However,
inside a chmod-777 directory, I cannot create files or directories
(which might be as expected).

After configuring User Name Mapping to map my Windows account to the
UNIX account, I can mount the share with the expected uid/gid.
Although I can read user-only files and directories, I still cannot
create any files or directories.  Windows keeps reporting that the
drive has write-protection enabled.

I know this isn't a SFU help forum, but any ideas to try or tips on
troubleshooting the NFS side is more than welcome.  Thanks in advance.

P.S. On an unrelated sidenote, does mountd always bind to the same
ports by default?  If not, is there a way to fix them at certain
values, so that PF rules can be written to match?  Linux rpc.mountd(8)
supposedly has a -p option that can be used for this purpose.
