If for some reason you lost your SSH server keys, sshd will fail to start with error:

Could not load host key: /etc/ssh/ssh_host_rsa_key
Could not load host key: /etc/ssh/ssh_host_dsa_key

You can recreate your host keys with these commands:

ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key
ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key

After recreating the keys, you will probably have to let your clients know as with the change of keys, they'll probably get warnings about it (Linux SSH will not even connect until you kick out the old keys).
