Has anyone successful used Suse 9.2 amd64 as an NFS server? My NFS clients are being denied access. rpc.mountd is doing new and interesting stuff with /proc/net/rpc/auth.unix.ip/channel and /proc/fs/nfsd/filehandle which seem to be the source of the problem.

Yes I run 9.2 on Dual Opteron 250's as a NFS server without issues. It looks like a permission problem with your setup. Either you are trying to write to a read only mount or the mounted directory has read only permissions. Brad Dameron SeaTab Software www.seatab.com On Wed, 2005-02-16 at 10:29, Ahmon Dancy wrote:

This is the RPM's I have installed. nfs-utils-1.0.6-113 yast2-nfs-client-2.10.5-2 yast2-nfs-server-2.10.5-2 However I don't use yast to configure my NFS server. I do it by hand. Brad Dameron SeaTab Software www.seatab.com On Wed, 2005-02-16 at 10:40, Ahmon Dancy wrote:

I discovered that the problem was that SuSEconfig (or something) mounted a second instance of procfs on /var/spool/postfix/proc, but it mounted it read-only. It appears that, as a side effect, this main the primary instance of /proc read-only as well. This was preventing rpc.mountd from doing what it needed to do in /proc/net/nfs. Issuing: mount -o remount,rw /proc kicked things back into working order. Ahmon Dancy wrote:
