Your client is complaining about the new host key. You need to remove the old hostkey from your *CLIENT'S* known_hosts file. The message is telling you what it doesn't like "Offending ED25519 key in /home/rshepard/.ssh/known_hosts:2".
So, you can use an editor to remove the offending line 2, and you'll be asked to accept the new hostkey the next time to connect. -- Russell On Wed, Apr 19, 2023 at 2:23 PM Rich Shepard <rshep...@appl-ecosys.com> wrote: > On Wed, 19 Apr 2023, Rich Shepard wrote: > > > Should salmo's id_ed25519.pub be in caddis' .ssh/authorized_keys? > > I think that I found the problem: salmo's id_ed25519.pub has only one line > and it's for a host no longer on the LAN. > > So, I'll generate a new keypair for salmo, using the same passphrase, then > copy that public key to caddis. > > Well, when I somehow, unintentionally, FUBAR a host I don't do it halfway. > Sigh. > > More when I make these changes. > > Rich >
