I recently cleaned up a few server in my home lab. Deleted servers that I no longer
needed. However It seems I have a server with an IP address that used previously.
FreeIPA is reporting that it is in /var/lib/sss/pubconf/known_hosts but I can't
reverse engineer the hostname by doing sshkey -R 1.2.3.4. I have run into this issue
previously but it has bee quite some time. When I go to delete the line from
/var/lib/sss/pubconf/known_hosts it is gone. If someone could help me that would be
great. I didn't see anything on my FreeIPA master that indicated I did anything
there.
