/etc/exports permissions

Unix Administrator_6 — Wed, 27 Sep 2000 16:10:06 GMT

It currently looks like:

/vol1 -anon=65534,async,root=hp3
/oracle/backup -anon=65534,async
/var/opt/ignite/clients -anon=2,async,ro

I want to give oradba and root rw access and everyone else ro.

How do I do this?

Thanks in advance!

The permissions in exports say how the filesystem is allowed to be mounted on the remote system. This is independant of the user accessing it. To achieve what you require export and mount the filesystem read-write, and use the UNIX file and directory permissions to make everything read only as required.

make these filesystems owned by oradba
do a chmod -R 711 on all the filesystems
use root=hp3 and
rw=hp3
now when these are mounted the machine hp3 will have full root access and oradba will have rw access but all others will only have read only access.
i.e rwxr--r--

This is a correction to Tony's reply.
chmod -R 711 is wrong, 744 is correct; however, this would hit directories too.
Better is:
find /mydir -type f -exec chmod u=rwx,g=r,o=r {} ;
NOTE: assuming the files are owned by oradba:dba, you will have also locked out all other accounts in the group 'dba'.

Sheri,

Take a backup first!!

I would advise caution in chmod-ing files if this directory contains an application like the Oracle rdbms.

Permissions on this are set correctly as designed by Oracle and changing them is very likely to cause the application to fail.

If this contains Oracle data files, then just check the database still starts after changing the permissions, and restore from the backup if there are any problems.
