SSHD could not load host key
I am using Ubuntu, and I used apt-get to install ssh and openssh-server. When I try to run /usr/sbin/sshd it says it could not load host key. It gives me a problem with sshd_host_key. It is the only file I don't have. I tried to turn it off, but apparently I am not commenting and changing the correct lines in my sshd_config to turn it off. Does anyone know how to turn RSA keys off?
