Managing User Levels
You can use the userlevel command to protect the system from
unauthorized use. The system provides three password-protected access
levels to the shell commands as well as to the visibility of system data.
By default, the user levels are not in use.
You can manage user levels with the userlevel command when the
service connection is open. The command has the following syntax:
userlevel [level ]
To check the current setting, give the command alone, without
parameters. When you want to change the level, give the command with
parameters. When you change the level to a higher one, a password is
required. When you change the level to a lower one, a password is not
required.
To change the password for the level, give the command with the
appropriate level and the set parameter. For this operation, the user level
has to be the highest, that is, 5. The new password is effective
immediately.
To remove the password for the level, give the command with the
appropriate level and the clear parameter. For this operation, the
effective user level has to be the highest, that is, 5. The new password
is effective immediately.
CAUTION Improper use of the userlevel command may lead to a malfunction of
the QML logger.
where
level
= 1, 3, or 5
set = Sets the password for a level
clear = Clears the password from a level
CAUTION Setting a new or clearing an existing user level is effective only after a
reset. When setting a new level or clearing an existing one, be sure to
reset the system before closing the service connection. Otherwise, you
may not be able to access the system without a cold reset.
