Four key pairs are provided based on the algorithms dsa, rsa, ecdsa and ed25519. Public and private host keys are automatically generated in /etc/ssh by the sshdgenkeys service and regenerated if missing even if HostKeyAlgorithms option in sshd_config allows only some. from the /etc/issue file), configure the Banner option: To allow access only for some users add this line: Whenever changing the configuration, use sshd in test mode before restarting the service to ensure it will be able to start cleanly. Sshd is the OpenSSH server daemon, configured with /etc/ssh/sshd_config and managed by rvice. For example -oKexAlgorithms=+diffie-hellman-group1-sha1. Some options do not have command line switch equivalents, but you can specify configuration options on the command line with -o. With such a configuration, the following commands are equivalent All options can be declared globally or restricted to specific hosts. The client can be configured to store common options and hosts.
