NFS can not mount a read-only export

[Barry Nelson_3]

I have an iso image that I am exporting from a Linux server as read only, no root squash. When I try to mount the NFS share on my HP/UX 11.11 client, I get "Permission Denied". Other NFS shares from the same server mount fine.

/mnt0 has the iso mounted:
mount -r -o loop "/images/Cache version 5.021.iso" /mnt0
Then I restart NFS
It (/mnt0) gives the error on the HP/UX client, /mnt1 and 2 mount fine.

Here is the exports file from the Linux server:
# See the exports(5) manpage for a description of the syntax of this file.
# This file contains a list of all directories that are to be exported to
# other computers via NFS (Network File System).
# This file used by rpc.nfsd and rpc.mountd. See their manpages for details
# on how make changes in this file effective.
/mnt0 *.bhssf.org(ro,async,no_root_squash)
/mnt1 *.bhssf.org(ro,async,no_root_squash)
/mnt2 *.bhssf.org(ro,async,no_root_squash)

Hi Barry,

What is the exact syntax you're using to mount the filesystem from the HP-UX client? What is the exact message it returns?

Hi,

Could you paste the output of the following command when run on Linux server.

showmount -e
showmount -a
