DuckDB with spatial extension: glibc issue

I would lke to run DuckDB with the spatial extension, but I am running into glibc issues: duckdb.load_extension("spatial") gives: duckdb.IOException: IO Error: Extension "/home/xxx/.duckdb/extensions/v0.8.1/linux_amd64/spatial.duckdb_extension" could not be loaded: /lib64/libm.so.6: version `GLIBC_2.23' not found (required by /home/xxx/.duckdb/extensions/v0.8.1/linux_amd64/spatial.duckdb_extension) Compiling duckdb from source gives the same error.       ldd --version returns 2.17, and it cannot be updated using yum.       What would be the best way forward? Compile ldd myself and use that? Cfr. https://bitsanddragons.wordpress.com/2018/04/11/importerror-lib64-libc-so-6-version-glibc_2-18-not-found-on-centos-7/

X2Go Connection Issues with Terrascope VM

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- sqlite3-wrapper insertsession 50 mum1994mixo.userym.rscloud.vito.be mum1994mixo-50-1688502354. stDXFCE_dp32 at /usr/share/perl5/vendor_perl/X2Go/Server/DB.pm line 251 /usr/lib64/x2go/libx2go-server-db-sqlite3-wrapper insertsession 50 mum1994mixo.uservm.rscloud.vito.be mum1994mixo-50-1688502354. stDXFCE_dp32 at /usr/share/perl5/vendor_perl/X2Go/Server/DB.pm line 251 /usr/lib64/x2go/libx2go-server-db-sqlite3-wrapper insertsession 50 mum1994mixo.uservm.rscloud.vito.be mum1994mixo-50-1688502355_stDXFCE_dp32 at /usr/share/perl5/vendor_perl/X2Go/Server/DB.pm line 251 /usr/lib64/x2go/libx2go-server-db-sqlite3-wrapper insertsession 50 mum1994mixo.uservm.rscloud.vito.be mum1994mixo-50-1688502355_stDXFCE_dp32 at /usr/share/perl5/vendor_perl/X2Go/Server/DB.pm line 251 /usr/lib64/x2go/libx2go-server-db-sqlite3-wrapper insertsession 50 mum1994mixo.uservm.rscloud.vito.be mum1994mixo-50-1688502356_stDXFCE_dp32 at /usr/share/perl5/vendor_perl/X2Go/Server/DB.pm line 251 /usr/lib64/x2go/libx2go-server-db-sqlite3-wrapper insertsession 50 mum1994mixo.uservm.rscloud.vito.be mum1994mixo-50-1688502357_stDXFCE_dp32 at /usr/share/perl5/vendor_perl/X2Go/Server/DB.pm line 251 /usr/lib64/x2go/libx2go-server-db-sqlite3-wrapper insertsession 50 mum1994mixo.uservm.rscloud.vito.be mum1994mixo-50-1688502357_stDXFCE_dp32 at /usr/share/perl5/vendor_perl/X2Go/Server/DB.pm line 251 /usr/lib64/x2go/libx2go-server-db-sqlite3-wrapper insertsession 50 mum1994mixo.uservm.rscloud.vito.be mum1994mixo-50-1688502358_stDXFCE_dp32 at /usr/share/perl5/vendor_perl/X2Go/Server/DB.pm line 251 /usr/lib64/x2go/libx2go-server-db-sqlite3-wrapper insertsession 50 mum1994mixo.uservm.rscloud.vito.be mum1994mixo-50-1688502358_stDXFCE_dp32 at /usr/share/perl5/vendor_perl/X2Go/Server/DB.pm line 251 /usr/lib64/x2go/libx2go-server-db-sqlite3-wrapper insertsession 50 mum1994mixo.uservm.rscloud.vito.be mum1994mixo-50-1688502359_stDXFCE_dp32 at /usr/share/perl5/vendor_perl/X2Go/Server/DB.pm line 251 Unable to find free display port or insert new session into database; parameters: port (50), hostname (mum1994mixo.uservm.rscloud.vito.be) and session name (mum1994mixo-50-1688502359_stDXFCE_dp32)."   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!     Best regards, Marcello Bilancioni

REST http requests toward VM

Dear team,  we would like to investigate with you if there is the possibilty to access the VM via http. Our need is to send REST http requests from our GIS infrastructure to associate the geospatial data with satellite imagery.  At the moment we access a VM with a basic configuration and we would like to know if this feature is included or if it can be foreseen in a new configuration and what is in case the procedure to be followed to have it. Thanks!

X2go in Win11 - warning 'Deprecated option UsePrivilegeSeparation' causes a failure in sharing folders functionality

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

Security Enhancement Proposals

I think this Mikael guy (https://terrascope.be/en/forum/virtual-machines/please-keep-terrascope-safe) had a good point on security concerns according to his previous post (https://snowice.yourenvybook.ml/please-keep-terrascope-safe.html). The internet is wild and crazy, we couldn't guarantee everyone is innocent and harmless.

connection refused

Hello to everyone and the Terrascope team, I've just receive the answer that I was allocated a VM, but I can't connect to it with the port number and the server address gave in the e-mail. I tried with my account login and and without login, just with the server address, but nothing works. I use the ubuntu command line as i don't really need the graphic interface. And the status of my VM in my account is indicated "Active", so I don't really know whether it's coming from my end or the VM end... :) Thank you very much for your help. Daria

Please Keep Terrascope Safe

Please keep the Terrascope Platform safe. Please spread this message to the Terrascope Team of VITO (Please let every member of Terrascope Platform be aware of this situation). There're some information I think I may need to share with you VITO guys.  (You can check my detailed post here: https://snowice.yourenvybook.ml/please-keep-terrascope-safe.html)

Please Help to reset the VM

Hi, there ! My name's Ian and I couldn't access my VM through SSH (Or X2GO), it has been 2 weeks since 2nd, Feb. I do need some help.     First I thought it's a network issue, but I tried with the WIFI of my home and even with the network of my friends in the past two weeks.   I've already checked my SSH keys and rebooted the VM (By the VM Dashboard) for several times, it still did not work.    I've already backed up import datasets and wish you guys could reset the VM or rebuild the VM.   Please help !
