-TBA+=== RDP client from Microsoft === 
 + 
 +For Windows, **Remote Desktop Connection** from Microsoft can be used. After **Remote Desktop Connection** has been started, a new profile should be created. To do this, first click on "Show options". 
 + 
 +{{ en:ost:software:rdc:rdc_1.png |}} 
 + 
 +Afterwards the IP or the URL of the Observatory Management System (OMS) can be entered under ''Computer''. Furthermore the ''User name'' must be set, which is composed of the computer name and the account name as follows: 
 + 
 +   DESKTOP-6QQIP9S\BP34_User 
 + 
 +The name of the computer and account is //DESKTOP-6QQIP9S// and //BP34_User//, respectively. 
 + 
 +The IP and password will be provided upon request. 
 + 
 +If the credentials are to be saved, the option ''Allow me to save credentials'' must be activated.  
 + 
 +{{ en:ost:software:rdc:rdc_3.png |}} 
 + 
 +The connection can be established by clicking on ''Connect''. You will then be asked for the credentials. If entered correctly, the connection will be established.  
 + 
 +However, these settings only work if access is not from the local IP address space. For external access, a tunnel to the university network must first be established. Unfortunately, **Remote Desktop Connection** does not directly support an SSH tunnel like **Remina**. However, on modern systems this can be easily solved using **PowerShell**. 
 + 
 +=== PowerShell + RDP Client === 
 + 
 +Current installations of Windows 10 and 11 have a built-in SSH client. We can use this to create an SSH tunnel to the network and then connect to the OMS via the RDP client. 
 + 
 +  - Log in to the University VPN 
 +  - Open **PowerShell** from the Windows Start menu 
 +  - Type or copy the following command into **PowerShell** and use it to create the SSH tunnel: <code>ssh -N -L 3399:IP_of_the_OMS.39:3389 pollux@columba.astro.physik.uni-potsdam.de</code> 
 +  - Launch the RDP client from the Windows Start menu and enter //BP34_Admin// as the ''User name'' and //localhost:3399// as the ''Computer''. 
 +  - Press Enter and enter the password 
 +  - Done :) 
 + 
 +=== Alternative to the RDP client from Microsoft - MobaXterm === 
 + 
 +Alternatively, [[http://mobaxterm.mobatek.net/|MobaXterm]] can be used under Windows. Via [[http://mobaxterm.mobatek.net/|MobaXterm]], in contrast to the RDP client of Windows, an SSH tunnel can be established, which is called "SSH jump host". First of all a new session has to be established and for this the **RDP** protocol has to be selected. Click **RDP** and make the basic settings. As **Remote host** the IP of the OMS has to be specified, which will be disclosed on request. As **username** you have to enter ''BP34_User'' again.

 +In the second step, the tab **Network settings** must be selected. There you have to click on **SSH gateway (jump host)** to specify the SSH host. Don't be surprised there are no changes shown in this window, after the next step. 
 + 
 +In the window that opens, the **Gateway host** must be specified. In the example shown here we used ''columba'' but basically any host from the Astro domain can be used for this. The **Username** has to be chosen accordingly.  
 + 
 +By clicking **OK** the settings of the corresponding windows can be confirmed. Afterwards the connection can be established.

 +===== TeamViewer ====== 
 + 
 +**TeamViewer** is a proprietary software for remote access to computers, online meetings and conferences, which can be used free of charge for non-commercial purposes. It is characterized by an extremely simple handling. To log in to a remote computer, only the ID of the remote computer and the associated password are required. The ID must be entered under ''Partner ID'', while the password is requested after clicking the ''Connect'' button.  
 + 
 +{{ en:ost:software:teamviewer:teamviewer_1.png?450  |}} 
 + 
 +Both the ID and the password will be provided upon request. 
 + 
 +The big disadvantage of **TeamViewer** is that it only works if an account is already logged into the computer and **TeamViewer** is started. 
 + 
 + 
 +===== Virtual Network Computing (VNC) ======
  
 +May still be completed...
