5.3.2 Kernel modules
5.3 Standard modules
The module Kernel modules offers the possibility of loading or unloading existing kernel modules. The
start page contains a search mask for searching kernel modules. Apart from selecting the module cat-
egory, such as drivers/video or drivers/usb, and the name, the user can restrict the display to loaded
modules.
In the search list, each module will be displayed and can be loaded or unloaded after prior confirmation.
5.3.3 VNC
The VNC protocol (Virtual Network Computing) can be used to display graphic screen outputs from a
distant computer on a local computer. This module allows the displaying of the desktop in the web browser,
see Figure 5.3.

Once the module has been loaded, a password must be entered, which can later be used to start the
VNC session. The password is saved in an encrypted form in the .vnc/passwd file in the user’s home
directory. If the file is deleted, the request is shown again.
A check is then run to determine whether a VNC server is already running. If no VNC server is running,
a VNC server can be started using the Start link. As soon as a VNC server is running, it can be stopped
using the Stop VNC server link or a connection can be created to the VNC server. To do this, a java applet
is loaded in the web browser and the UCS system can be accessed graphically in the web browser.
