| Check if the anon option is set correctly for exported file systems. List exported file systems. # exportfs -v Each of the exported file systems should include an entry for the 'anon=' option set to -1 or an equivalent (60001, 60002, 65534, or 65535). If an appropriate 'anon=' setting is not present for an exported file system, this is a finding. |
