On both operating systems, you should be able to regenerate new ssh host keys with the commands: [root@machine ~dir]# ssh-keygen -t rsa -f ssh_host_key.pub [root@machine ~dir]# ssh-keygen -t rsa -f ssh_host_rsa_key.pub [root@machine ~dir]# ssh-keygen -t dsa -f ssh_host_dsa_key.pub On Mac OS, these commands should be issued while you are in the etc directory, and you should use a sudo before them.
