NFS mount of HP-UX 9 filesystem fails on HP-UX 11i

[Lyn Doose]

When I try to NFS mount a filesystem on an HP-UX 9 system onto an HP-UX 11i system, I get the following error (from SAM):

nfs mount: get_fh: wgse.LPL.Arizona.EDU:/gse/Log server not
responding : RPC: Authentication error; why = Invalid client credential

HP-UX 10.20 systems can mount this same filesystem without any errors. I've verified that I'm exporting this filesystem to both the 10.20 and 11i systems.

Any idea what the problem is?

On hp-ux 9 systems I believe the default protocol used by nfs is udp, whereas on 11i the default is tcp. try giving an option -proto=udp while mounting.

The above should work if the udp based nfs service is running on your 11i machine. check by rpcinfo -p - that should show a udp service running for nfs.

Hi Lyn

I don't have hpux-9 machine to check this problem, propably you can try these out.

An HP-UX 9.x system is neither an NFS client by default nor an NFS server. It may become either by modifying /etc/netnfsrc. Change:

NFS_CLIENT=0
NFS_SERVER=0
START_MOUNTD=0

to:

NFS_CLIENT=1
NFS_SERVER=1
START_MOUNTD=1


The automounter will start automatically on HP-UX 9.x if there is a valid auto.master NIS map. To use /etc/auto.master, modify the line in /etc/netnfsrc2 where the automounter is started so that the automounter is started with the -f option:

/usr/etc/automount -f /etc/auto.master

Assuming the above posts work, is there a possibility he needs to patch his system? If so, I think there still is a library of HP-UX 9.X patches.

Its worth looking into, though I never did real administration work on anything below 10.20.

I checked rpcinfo -p, and indeed a UDP service is running on the 11i system. However mounting with the UDP option still results in the same error message.

NFS_CLIENT and NFS_SERVER in /etc/netnfsrc are already set to 1. START_MOUNTD seems to be a illegal entry in this file.

I guess the old client machine is actually HP-UX 8.0. uname -a returns:
HP-UX WGSE B.08.00 A 9000/42T 080009321edb

There is no option to start the automounter in /etc/netnfsrc2.

So thanks anyway, but I'm still stuck!

Sorry about that. This is like real primitive. I can't imagine a big hp-ux box running hp-ux 8. Well, coming back to your problem, the error you seem to be getting is that of authentication and 'Invalid client credential'. Have you looked into this issue? Just some more thoughts - Sorry if this is not useful.

Hello.
Beginning with HP-UX release 10.30, there are two versions of NFS available: Protocol Version 3 (PV3) and Protocol Version 2 PV2). Releases HP-UX 10.20 and earlier only have PV2 available. The default for mounting from a server on HP-UX 11 and 11i is PV3. You can use enhanced mount command to specify which NFS version should be mounted, see man 1M mount_nfs. Hope it will help, cause i never tried to do it by myself.

Example from man pages:
To mount an NFS file system over Version 3:
mount -o vers=3 serv:/usr/src /usr/src
