@mikewalsh's recent mention of dukto reminded me that I had it stored somewhere. Found it in my Bionicppup64 storage folder. I think it was version 4.9 and wasn't sure it was for 64bit systems. So I tracked down the latest 64bit for Linux (packaged as an rpm) and repacked it as an AppImage. (Thanks, fredx181 for that application). Runs under Fossapup64 and Bionicpup64. Fails under Bookworm and Jammy64. See my next post.

Remove the false '.gz' Place anywhere. Check that it's executable. Left-Click to run.
The Windows version program can be obtained here, https://sourceforge.net/projects/dukto/
@mikewalsh, I've never actually used this app. When it opens it presents the display you showed at the above link. It automatically finds the address of the operating system from which it's being run. At the bottom of its GUI is a Button named Addresses. Is establishing a connection as simple as having dukto running under the operating system you desire to send-to and selecting its address from a list that will appear when the Addresses button is clicked? Or something else?
