Please inspect the list of static NetBIOS name mappings generated by names2lm carefully before using NT WINS manager to import them into a WINS database.

As a rule, you should keep the number of static mappings within WINS as small as possible and use them only for important computers which are not WINS-aware. It is not recommended to use static mappings for WINS enabled clients.

7.3 System administrator tools

The first section contains an overview how access permissions are managed in Advanced Server for UNIX. The following scripts are required by system administrators in different situations. For example, they can be used for backing up the user’s configuration and resources as well as for problem analysis.

7.3.1 Access permissions in Advanced Server for UNIX

Advanced Server for UNIX stores access permissions for files and directories in its ACL database in the /var/opt/lanman directory. In contrast to UNIX permissions, which are stored with each file and directory in the file system, permissions are stored centrally in Advanced Server for UNIX.

The ACL database stores access permissions for some resources, while other resources inherit their permissions from the higher-level directory. The net perms command displays permissions for all available resources, i.e. either permissions stored 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 permissions are not saved and copied automatically. Files and directories can be backed up together with their permissions using the NT Backup Tools, for example.
