Citrix

Here you will find instructions on how to install and configure the Citrix software for accessing the (new) Windows Terminal Server xats01.gsi.de or to use it via a web browser.

Microsoft has changed the license policy since beginning of 2015. That is why all needed Windows accounts have to register in a special group in our active directory. You may request this via an email to the ticket system (windows-service at gsi.de).  

You can still use your Citrix client, but you will need to set up a new account for the new Terminal Server Farm.

Start the Citrix receiver and log in. You will now see the apps of the old farm.

Left-click the small arrow next to your account and select Accounts:

Both accounts are now visible. Please remove the account for wts.gsi.de that no longer works.

(Select - Remove)

After OK you will see all apps released for you in the new farm.

With Citrix Receiver, you are able to access to the Windows Terminal Server from outside the GSI Windows domain.
So GSI Windows environment (data, e-mail, SAP, etc.) is available. To establish the connection, client software must be installed and configured on the device.
The Citrix Receiver is available for all standard operating systems at GSI:

Windows

There are different ways for software installation depending on you are located inside or outside the GSI domain:

Linux

To establish the connection can take quite a while depending on your internet access.

  • Users of a Windows operating system should always use the client. (see above) 
  • Users of a Linux operating System are able to use the new version of the Citrix client with the web browser of your choice for working on a Windows Terminal Server. Type the address https://xats01.gsi.de into the address bar.

This opens the start Screen. Log in with your Windows user name (without campus) and password:

The login procedure can take several minutes.

All needed certificates are already installed on Citrix installations on Windows / Linux supported by Base-IT or HPC.

In other cases you must install the following certificates:

Linux - outside

Ubuntu: Save the certificates in PEM format in the directory /opt/Citrix/ICAClient/keystore/cacerts
If necessary, execute the command /opt/Citrix/ICAClient/util/ctx_rehash.

To convert a certificate file from DER to PEM you may call the following command:
openssl x509 -in file.crt -inform der -out file.pem -outform pem

Please note that the path could be different in other distributions or Citrix Versions.

You may need to delete the Citrix certificate directory completely and create a symlink to /etc/ssl/certs instead.

Start manually

Windows 7: Start (all)Programs Citrix Receiver

Windows 10: Start Citrix Receiver

Explorer labels

In the explorer you can see

  • the drives (without the floppy) of your (local) PC and
  • the drives on the Terminal Server.

The drives of your own PC have the label on your client, example: on DEPCnnn. The network drives on the terminal server have the name of the server or DFS, e.g. \winfilesvi\... or \campus\...

Close your der Terminal Server session

If you want to close a terminal server session, always choose Start - Log off.

It is also possible to leave the session in order to continue it at a later time. In this case, choose the corresponding function from the toolbar.

The past has unfortunately shown that this occasionally leads to problems and prevents a later registration. In these cases, contact the UHD or create a ticket at windows-service(at)gsi.de.
