RDS at D-ITET

ISG.EE provides a RDS environment that allows all D-ITET employees to access a session-based Windows server. This server hosts several Microsoft programs as well as some other software, most of it runs on Windows only. For your daily work, ISG.EE recommends to setup a RDP client (not web browser based).

RDS Connection

• Your user name has to be a member of the AD group itet-all-users (check out the troubleshoot section below)

• Please use VPN in order to connect successfully from external networks.

We offer several ways how to connect to the RDS servers:

Linux, MacOS X, Windows (Web Browser Based)

• Open a web browser and point it to one of those pages:

• https://worli.ee.ethz.ch (welcome page with both mentioned options below)

• https://worli.ee.ethz.ch/RDweb/webclient (supports audio forwarding)

• https://worli.ee.ethz.ch/myrtille (better scroll behavior)

Myrtille is an open source Git project, based on FreeRDP. You can change the name of the destination server. This allows you to use it as a web based RDP client to connect to any computer at D-ITET (theoretically).

Linux

Example with FreeRDP (version 2.0.0 or newer):

• Connect to https://worli.ee.ethz.ch/RDWeb

• Login with your nethz credentials: "d\USERNAME"
• Download the rdp file to a location you remeber and name it SERVERNAME.rdp (for example vela.rdp)

• xfreerdp SERVERNAME.rdp /gu:USERNAME /gd:d /u:USERNAME /d:d

Users with ISG.EE managed Linux workstations have the option to use the SEPP package xfreerdp-2.0.0.

Advanced commands

MacOS X

Example with Microsoft Remote Desktop 10 Client for Mac:

• Install "Microsoft Remote Desktop 10" from apple app store
• Setup the gateway worli.ee.ethz.ch
• Configre both users, the gateway and the RDP user with "d\USERNAME"
• Launch your connection

Screenshots of the login procedure

MS Windows

Example with Default mstsc.exe RDP Client:

• Go to https://worli.ee.ethz.ch/RDWeb and login

• Download the *.rdp file for the connection you would like to use.
• Enter "d\USERNAME" and password and wait for the user profile to load.

Advanced Setup

Known Issues

MS Webclient

• Bad Scroll behavior with Firefox and Chrome
• Colors can appear slightly too bright
• Sometimes black page when resizing browser window (reconnect necessary)
• Annoying copy paste warning "Confirm the copy to your local clipboard"

Myrtille Webclient

• No audio support
• Not as fast as MS Webclient when working with 3D apps or video streams
• Scaling not possible after login. Only zooming function (not really an issue).
• Slightly different colors
• Can be CPU hungry if screen changes a lot

FreeRDP

• Sometimes buggy, when working with 2 physical monitors (some lines can flicker)
• Steals focus of gnome-screensaver when active so entering a password is impossible
