I think it is because I just changed the prefer hostkey algorithm from ECDSA to ED25519 and not because of the UpdateHostkeys. Maybe CheckHostIP should be relaxed to not consider IP address lines in known_hosts when the key type there is a lower priority algorithm than the selected hostkey type. I need to think about it. -d _______________________________________________ openssh-unix-dev mailing list openssh-unix-dev@xxxxxxxxxxx https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev
