John: There's a command ssh-keygen. Read it's man page, as there's a bit to do to set ssh up properly. Once you've generated your keys, and copied the public ones where they need to go, you'll still see a message like the one you posted the first time you connect. Simply say "yes" to add the machine. Thereafter, you won't see this message again until you upgrade one of the two systems, at which time you'll be doing this all over again (or you'll get smart and just backup /etc/ssh/* before hand, and then restore those files after your upgrade). The knownhosts file in your $HOME/.ssh/ directory is where thesze things will be written, so if one stops working, open that file and delete the line that points to the machine that isn't working anymore. That will bring up the same "unauthenticated" message, and you're off to the races again. Isn't this world a friendly place? Not. Sometimes, I miss the good old days, not so many years ago, where it was reasonable to not lock one's doors--even in fairly large cities. On Wed, 14 Aug 2002, John J.
