40 CHAPTER 5. USAGE
permissions inherited by the user’s ancestors only. That means an empty permission list of a user
does not imply that the user has no permissions at all but that he has exactly the same permissions
as inherited from the groups he belongs to.
The right of one user for changing another user’s or group’s access rights is determined by the
parent/child relationship between them. When one user is creating another user, he will implicitly
become the parent of that new user and hence has the right to change his permissions. More
general, a certain user has the right to change another user’s or group’s permissions in case he
stands higher in the ancestry than the other one. The ‘super’ user stands at the top (or the root)
of the ancestry, hence has the right to change everybody’s permissions.
Additionally, there is the restriction that a user can never give more permission to others than
what he has. For example, if a user has no permission to change the network settings he won’t be
able to grant this right to somebody else. However, a user has always the right to reduce the set of
permissions of his descendants.
In order to change the permissions of a user/group you have to select the user/group first. This is
done using the selection list at the top of the User/Group Permissions panel (see Figure
5.20 on the
preceding page). The selection list will show only users and groups for which you have the right to
change their permissions. Next, clicking the ‘Update’ button will show the permission list of that
user. Every right in the list has a permission value, which is explained in Table
5.8 .

Add a permission
Once you have brought up the user’s permission list, select the permission entity in the list box
below and click the ‘Add’ button. The permission entity will be added to the permission list having
a default value. Change the permission as desired. Once all permissions have been set, click the
‘Apply’ button.
Delete a permission
Check the ‘Delete’ check box right of the desired entry in the permission list and click ‘Apply’.
5.5.3. Network Settings
The Network Settings panel as shown in Figure 5.21 on the facing page allows changing network
related parameters. Each parameter will be explained in Table 5.9 on the next page. Once applied
the new network settings will immediately come into effect.
