Check Text ( C-43382r1_chk ) |
---|
Check if the nfs-kernel-server package is installed. It contains the exportfs command as well as the nfsserver process itself. # rpm –q nfs-kernel-server If the package is not installed, this check does not apply. If it is installed, check the permissions on exported NFS file systems. Procedure: # exportfs -v If the exported file systems do not contain the ‘rw’ or ‘ro’ options specifying a list of hosts or networks, this is a finding. |

Edit /etc/exports and add ro and/or rw options (as appropriate) specifying a list of hosts or networks which are permitted access. Re-export the file systems. |
