Commit https://github.com/openssh/openssh-portable/commit/c63c9a691dca26bb7648827f5a13668832948929 add this description If this option is set to ânoâ (the default) then only addresses and not host names may be used in ~/.ssh/known_hosts from and sshd_config Match Host directives. to UseDNS option in sshd_config. I believe there should be authorized_keys instead of known_hosts so it will make sense on the server side, as also the commit message hints: > for host matching in sshd_config and authorized_keys. Related to bz#2405 (unlike the commit message referring to bz#2045).
