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. --david 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.
Are most of your clients going to be windows machines? if so, you should thing seriously about using samba. ( you should also read http://www.openbsd.org/mail.html and include all even vaguely related config files and output of things like dmesg i notice you're using 'david:guest' here... the first question Please provide specifics? do you mean with the david:guest uid:gid what user:group are the parent directory? david:guest, or something man mountd ( http://www.openbsd.org/cgi-bin/man.cgi? query=mountd&apropos=0&sektion=0&manpath=OpenBSD +Current&arch=i386&format=html )
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
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 would like to have a global mount, say drive g: to mount from my home directories. Is it possible? How have you been doing in order to get a global drive mapping? Thanks in advance.
I think it might be better to ask in the forums at the SFU website: http://www.interopsystems.com/tools (Unless you are having problems on the OpenBSD side.)
I followed Microsoft's instructions for SFU and found that it worked quite well if all I cared about was read-only access. I didn't have any further success even after installing a bunch of SFU hotfixes (http://www.duh.org/interix/hotfixes.php). My troubleshooting seemed to indicate that the write requests were being denied somewhere inside the kernel, for reasons unknown. I didn't have the time or interest to pursue it any further, so I went back to samba and let the thread die. --david
I have the exact same issue hereFreeBSD works fine, OpenBSD fails.
I'm new to NFS, so I'm not too clear on the best way to troubleshoot
this further, but if there's someone here who is good with NFS and
cares to resolve the issue on OpenBSD, I'd be happy to work with them.

On Mon, 16 Jul 2007 07:46:20 -0600 Hi, I'm really interested in getting this working too, could you please send me offlist your sysctl -a output ? Thanks
On a whim I decided to change the transport protocol that the Client for NFS uses and my problem has gone away. By default "TCP+UDP" is used, but if I set this to just UDP or TCP (via nfsadmin client), and then restart the Client for NFS service, NFS largely works as expected--with UDP apparently providing a bit higher throughput over my WLAN. I haven't tried changing nfsd's flags on the server side instead, but this might work as well. Why "TCP+UDP" works for FreeBSD is unknown to me, but I'm content now. I guess it's one of those interoperability issues... -----------------------------------------------------------------------------
