Hi all,
I have a chmod problem using an NFS-mounted filesystem.

Client and server both 5.1B PK2

Server (alf1) exports filesystem with -root=fm01 option

On the client (fm01):

fm01_root> chmod 0 /nfs/alf1/tftpboot/junk
fm01_root> ls -l /nfs/alf1/tftpboot
total 3
drwxr-xr-x 33 root system 1024 Nov 26 14:58 ProX
drwxr-xr-x 4 root system 512 Dec 8 10:46 ProY
d--------- 2 root system 512 Dec 9 09:35 junk
fm01_root> chmod 7777 /nfs/alf1/tftpboot/junk
fm01_root> ls -l /nfs/alf1/tftpboot
total 3
drwxr-xr-x 33 root system 1024 Nov 26 14:58 ProX
drwxr-xr-x 4 root system 512 Dec 8 10:46 ProY
drwxrwxrwx 2 root system 512 Dec 9 09:35 junk

i.e. the 7000 bits are not getting set. And they are not
seen to be set at the server-end also.

If I set them at the *server*, they are seen by the client.

The problem goes away if the server is a Linux box, so it
looks like a problem in the Tru64 NFS server. Are there
any special export permissions required to permit the
setting of these bits? I couldnt see anything obvious in
'man exports'

Cheers,
Terry.
