Every attempt to connect to anything from a new FreeBSD system results in a "host key verification failed." ssh 127.0.0.1 even fails this way. I started with a new FreeBSD4.7 installation and un-tarred the contents of another 4.7 system to essentially clone this one. My tar ball purposefully did not have the /etc/ssh directory in it so as to not overwrite any of the files in the new installation so I ended up with all the proper key files like I should. I can successfully connect to the system from remote hosts so sshd is working. I even regenerated my own host key with ssh-keygen -tdsa and that worked. Is there anywhere else besides my directory and /etc/ssh I should look to see what got clobbered? It worked fine before I unpacked the tar ball. I even deliberately deleted all the host keys in /etc/ssh and made it regenerate new ones. Other than the expected effect of causing the remote systems to complain about the host identity changing, nothing else happened.
