hp toptools for openview nnm user guide
Figure 5-2 shows the Lock system dialog, which has several useful applications such as restricting access to a
system during a remote control session, or when implementing organizational security policies. Example: An
unauthorized user is trying to log into a critical PC as the local Administrator to change configuration settings. The
HP PC generates and sends DMI alerts to indicate an unauthorized user is making several unsuccessful attempts to
log in as the local Administrator. The OpenView NNM event log provides notification of this event. In response,
the NNM console operator can invoke the “Lock System” action. This action dynamically locks the keyboard and
mouse of the selected system preventing further unauthorized access.
Toptools actions can be performed against single or multiple targets. For example, a group of PC’s can be
prevented from a power-off via the front panel prior to a network-wide backup routine.
Figure 5-2. Locking the system prevents users from using the keyboard or powering off.
Some toptools actions directly control the power-state of the PC. The ability to power-on a system can be very
useful. For example: An administrator wants to install a new system software package on all the Kayaks in a
company. This can be done very quickly from the NNM station by executing a Find By-> Attribute – isHPKayak,
to select all Kayaks, going to the Tools -> HP Toptools -> Power On to awaken the Kayaks, then selecting the
Manage Drivers/Firmware menu item to distribute the new package.
Figure 5-3. Prevent Shutdown permits the user to still use the keyboard, but not power off the system.
The power-on password is also referred to as the DMI or WMI password. As DMI and WMI offer administrators an
extensive range of remote manageability, it is important to use DMI/WMI passwords to protect access to remote
management actions. The toptools menu item Set System Password gives the administrator access to change
DMI/WMI passwords for the protection of a single system, or for a collection of systems on a periodic security
maintenance schedule.
