Yes, that is correct. You comments here reminds me of a forum post or
whatever I read during my initial setup on the first machine months ago.
Thanks for jogging that memory cell loose.
So, in essence, manually running the 'troubleshooting command' (as I
call it) asks for the ssh password, thereby causing the server
acceptance and places the correct host info into the server known_host
file. Then ssh becomes fully passwordless access and BackupPC can
function properly.
Thanks again, all.
