    Before replying to your help below I can now connect from my Mac on
    the same LAN both with ssh to the IP of this machine and through my
    dynamic DNS address.  I'll try Bitvise from the local Windows
    machine soon.

 

And what about the ip address and port number?

Check your ip:

$ ip addr

    I should have replied ealier that the above gives the correct IP
    address.

Check which ports are opened:

$ sudo ss -tl4p

Check which ip/port ssh is configured for

$ sudo sshd -T | grep list

    paul@Joy4:~/music/pima$ sudo sshd -T | grep list
    listenaddress [::]:22
    listenaddress 0.0.0.0:22
    permitlisten any

I'll try the following in a while/

 Try to ping it from your Windows machine.

c:\> ping [your_linux_ip_addr]

does it work?

Then, try to connect to port 22 using telnet to see if connection could be made.

In Admin powershell

PS C:\>  Enable-WindowsOptionalFeature -Online -FeatureName TelnetClient

PS C:\>  telnet [your_linux_ip_addr]

Thank you,

Paul
