From Univention Wiki
XRDP is a daemon running on UCS, which allows users to open a X session on the server using the Remote Desktop Protocol (RDP). This protocol is natively supported by Microsoft Windows and many other operating systems and thus does not require additional software to be installed on the client PCs.
XRDP is available through the App Center and can be installed using the corresponding UMC App Center module.
By default all users of the UNIX group Domain Admins are allowed to connect using RDP. The name of the group can be changed by setting the UCR variable xrdp/access/admins.
Maximum number of concurrent sessions
The maximum number of concurrently running RDP sessions is by default limited to 10 and can be changed using the UCR variable xrdp/sessions/max.
Login window customization
The title and the images used in the login windows can be configured using the UCR variables xrdp/title and xrdp/imagedir.
The directory must contain 4 images using the Windows bitmap format. The first two are used as the rectangular logo at the left side on the input fields, the other two are used for the banner displayed below the input window:
- 24 bit color logo, 140 x 140
- 256 color logo, 140 x 140
- 24 bit color banner, 256 x 192
- 256 color banner, 256 x 192
- Microsoft Windows has a built-in RDP client. It will show a certificate warning as long as the UCS certificate has not been imported.
- UCS and many other Linux distributions include rdesktop and FreeRDP.
- For Apple iOS there is iResktop.
- For Android there are multiple apps.
Wrong keyboard layout
When you log into KDE using XRDP, the keyboard is configured to use the US layout by default. To change this open the K-Menu, switch to the Computer tab, open System settings, then open the Regional & Languages in the Personal section. There open Keyboard Layout, select Enable keyboard layouts and add the requested layout from the left list of available layouts. Click the right arrow to add the layout and reorder it to the top in the right list of Active layouts using the up/down buttons. Apply the changes and close the application.
- Virtual Network Connect provides a simpler protocol, which is used by KVM for example.
- only provides a text console by default, but can be used to tunnel X sessions natively.
