Hello fra81,
thanks for your answer. Some years ago I used the free version successfully without any problems and with sufficient speed via the same DSL-Line. So first I would like to try it in the same way again.
I just thought, that the amount of data, that is transferred, increases with the complexity of the GUI. Therefore I thought the GUI (Ubuntu, KDE or Gnome) would make a difference and without any GUI on the remote Ubuntu it would be fastest (I tried with XServer on Windows – that worked, but was too slow).
Attached you find the logs.
Best regards
