Hello everyone,

I'm reaching out because I've been having difficulties connecting to my Terrascope Virtual Machine through the X2Go client. I've closely followed the steps outlined in Terrascope's documentation, but I've been unsuccessful in my connection attempts on multiple computers.

Here are the key steps I've taken:

1 - Downloaded and installed the X2Go client for Windows from the official source ( https://wiki.x2go.org/doku.php/download:start ). I have a query regarding this: is there only the 32-bit version, or is there a 64-bit version available as well?

2 - Opened the X2Go client and added a new session.

3 - In the session settings, I inputted the following:

    Session name: "Terrascope VM"     Host: "uservm.terrascope.be"     Login: "mum1994mixo$"     SSH port: "24415"     Session type: "XFCE"     In the 'Connection' tab, I changed the compression method to '4k-png', as specified in the Terrascope guidelines.

4 - After saving these settings, I attempted to initiate the connection from the main X2Go Client window by double-clicking the session. I entered my Terrascope account username and a password. However, I encountered an error during the connection attempt that appears to indicate a server-side issue.

The error message in full is as follows:

"Connection failed. : /ust/lib64/x2go/libx2go-server-db-

I've double-checked all the entered details for accuracy and attempted the connection using different computers, but the issue remains unresolved.

Has anyone encountered a similar problem or can anyone help troubleshoot this issue? I'm happy to provide additional information if needed, or carry out any recommended troubleshooting steps.

Thank you in advance for your help!

Issue: Every time I open x2go I get this warning: /cygdrive/C/Users/<my_username>/.x2go/etc/sshd_config line 3:  Deprecated option UsePrivilegeSeparation. It causes problems to get filesharing on Windows working

- I didn't have this issue in Win 10 but I experienced this problem in Win11 

I've resolved it by:

Launch the Windows Terminal by right-clicking on the Start button. From the drop-down option near the + symbol, select the Settings menu (down caret "v") - Goto Settings - On the panel that opens, on the left side select Startup - On the right side, change "default terminal application" to "Windows Console Host" - Click Save - 

Now if you execute the X2go client the popup window no longer appears and the x2go shared folders functionality works
