7.3 System administrator tools

The first section contains an overview how access permissions a re managed in Advanced

Server for UNIX. The following scripts are required by system adm inistrators in different

situations. For example, they can be used for backing up the user’s con figuration and

resources as well as for problem analysis.

Advanced Server for UNIX stores access permissions for files and directories in its ACL

database in the /var/opt/lanman directory. In contr ast to U NIX per mission s, which are st ored

with each file and directory in the file system, permissions are stored centr ally in Advanced

Server for UNIX.

The ACL database stores access permissions for some resources, while other res ources

inherit their permissions from the higher-level directory. The net perms command displays

permissions for all available resources, i.e. either permissions sto red physically in the ACL

database or those inherited from the higher-level directory. If a resource which is not yet

entered in the ACL database is assigned permissions by net perms, the rights currently

inherited are combined with those specified in the command and stored as a physical entry

in the ACL database. If the physical entry is deleted, the inherited permissions are valid

again.

If you are saving files with UNIX tools or copying files under UNIX, the permissi ons are not

saved and copied automatically. Files and directories can be backed up together with the ir

permissions using the NT Backup Tools, for example.
