[comp.unix.ultrix] NFS mount problem Ultrix to AIX

david@phys.anu.oz (10/24/90)

I am having problems NFS mounting Ultrix (3.0 and 4.0) file systems on AIX 
3.1. The following message is produced even when the appropriate 
permissions are granted on exported directories.

# mount rsphy1:/users /mnt
mount: server rsphy1 not responding: RPC: Authentication error; why = 
Invalid client credential
nfsmnthelp: rsphy1: The file access permissions do not allow the specified 
action.
mount: giving up on:
        rsphy1:/users
The file access permissions do not allow the specified action.

I successfully mount between DECStations running Ultrix 3.0 and 4.0 and 
also between RS6000/320s including jfs and cd-rom file systems.
I can also mount from AIX to Ultrix successfully, and both ways SUNOS-AIX 
and SUNOS-Ultrix. Also Ultrix-Connection 1.3 on VMS will mount on Ultrix 
and AIX.

Has anyone out there successfully mounted Ultrix to AIX - are there any 
patches required/hacks to passwd & group files/whatever?

Local reps from both IBM and DEC have been unable to help so far.

Please post to "david@phys.anu.edu.au" if you can help.

The problem is in the type of ethernet packet in use.  Your RS6000 is using
Xerox Ethernet, whereas you Ultrix station is using IEEE 802.3.  If you
change your RS6000 to use IEEE 802.3 things will work.  For some reason
this doesn't show up in other protocols, and most of the mounting process
actually goes okay.  It's when the actual ..MOUNT.. request gets sent
that the 6000 sends a short packet and gets turned down.

I'm sorry that I can't tell you how to change your card's packet
type.  It has something to do with configuring for et0 instead of
en0, although netstat still shows en0 (isn't life great?).
