Managing the NWS filesystem

UnixWare users

UnixWare user accounts provide limited NetWare server administration such as installing NetWare Services, installing NetWare Directory Services (TM) (NDS), repairing NDS, setting up volumes, and so on. To use these administration tasks, you must be the System Owner on UnixWare and have permission to administer a NetWare server. (Root and the System Owner are given permission to administer NetWare Services when it is installed.)

When NetWare Services is installed and the hybrid user feature is not enabled, the following UnixWare accounts are used for all NetWare users but do not have hybrid user status:

nwroot is used by the NetWare ADMIN and server processes
nwuser is used by all NetWare users

Since NetWare Services runs as a privileged process, NetWare Services has the right to set a file's owner, group, and permission mask. All files created by NetWare users are owned by nwuser, assigned to nwgroup, and assigned the umask permission mask defined in the scoadmin(1M) NetWare Setup utility.

Considerations for NetWare UNIX Client (NUC) users

NUC users can log in to a NetWare server either through scoadmin or by using nwlogin(1nuc) and nwlogout(1nuc) at the UnixWare command line. See ``Command lines, operating systems, and networks'' for basic information on the UnixWare command line. The NetWare volumes can be accessed from scoadmin, from the automounter, or from the command line using mount(1M).

We suggest that UnixWare users who will be using UnixWare or NetWare servers be set up as hybrid users. This ensures that they are the owners of the files they create; otherwise, nwuser is the owner.

Note the following items:

UNIX mode volumes allow you to use your permissions if you are the owner. With NetWare mode volumes, if you are the owner, you are not granted privileges other than your effective rights.
As shown in the examples in UNIX mode, files created by nonhybrid users are owned by every other user with equal (nonhybrid) permissions. Your files can, therefore, be opened and modified by other users. For the security of users, we suggest that when using UNIX mode, you set users up as hybrid users.

The NUC adopts the following rules for files and directories:

The NUC attaches mapped IDs (from the /etc/netware/nwusers file or the default nwuser and nwgroup for nonhybrid users) on the inode when the file or directory is created in the UnixWare file system.
When checking files and directories, if the NetWare login ID maps to the ID on the inode, it displays the user's UnixWare UID and GID as the owner.

The following table may help you to understand how users are seen from NUC:

NUC behavior

User type ID on the inode Ownership as seen from NUC Action performed by NUC

Hybrid user 1 Mapped IDs of the hybrid user Native IDs Creates a file and lists the file for ownership.

Hybrid user 2 Not applicable Mapped IDs of the hybrid user Lists the file for ownership as created by Hybrid User 1.

Nonhybrid User 1 nwuser, nwgroup Native IDs Creates a file and lists the file for ownership.

Nonhybrid User 2 Not applicable Native IDs Lists the file created by Nonhybrid User 1.

User type	ID on the inode	Ownership as seen from NUC	Action performed by NUC
Hybrid user 1	Mapped IDs of the hybrid user	Native IDs	Creates a file and lists the file for ownership.
Hybrid user 2	Not applicable	Mapped IDs of the hybrid user	Lists the file for ownership as created by Hybrid User 1.
Nonhybrid User 1	nwuser, nwgroup	Native IDs	Creates a file and lists the file for ownership.
Nonhybrid User 2	Not applicable	Native IDs	Lists the file created by Nonhybrid User 1.
