There click on **Save** again to close this window, finally back in the Control Panel, click on **Apply**. +**Hint:** If you get an error saying not changes have been made when applying the changed configuration - even though you actually did change ciphers - DSM doesn't detect changed options in "customized ciphers". In order to apply them nonetheless, do the following steps as a workaround: + +* Note the currently-configured SSH port (default: ``22``) +* Change its value to something else such as i.e. ``222``, then click **Apply** +* Then revert the port setting to the previous value and click on **Apply** once more. + ## Limitations At least DSM version 7.2 doesn't allow you reaching a perfect score, since neither host keys, nor host-key algorithms can be updated or modified in a supported way other than by manually modifying ``/etc/ssh/sshd_config``. Also those manual changes are likely overwritten by i.e. system updates or other configuration changes via the DSM web interface.
