All of the above features first verify that the operation in question is necessary, e.g. the UFTP
daemon cannot be started on machines that are turned off, and machines that are already turned on
cannot be turned on again. A notification is logged of these situations into the Event log.
The treeview control on the bottom left side displays the image folders that exist on the server,
which can be retrieved by press the Get Images button. The folders are displayed hierarchically. The
size of a certain folder will be displayed in a tooltip by hovering with the mouse cursor over a certain
tree node.
To start a distribution process the target machines and the image folder to be copied must be
selected first. This doesn’t necessarily have to be a leaf node, since the subfolders are copied
recursively. Distribution is started by pressing the Start Copy button. Status events and errors during
will be displayed in the Event log.
Please keep in mind that the connection between the client and the service times out after 1 hour.
Should the client be left inactive for a long time, it might need to be restarted to successfully
administer a distribution process. If the distribution takes longer than an hour, the administrator
must increase the timeout period in the client and the service configuration likewise.
The following screenshot shows the user interface after querying the information of the test
machines, including one deliberately disallowed, loading the list of images, and finally performing the
distribution of an image folder:
