Hi, Not sure if this is the right place to post. When one of the ciphers listed under "Ciphers" in sshd_config does not exist, it refuses to start. This can happen when admins set their preferred ciphers and an update removed some ciphers. Admins can be locked out of remote machines after a reboot. I think it is better just ignore non-exist ciphers and generates warnings. Only exit when there is no ciphers available.
