This setup is the simplest method of authentication and uses SSH version 1.To enable SSH password authentication, use the following command.• Enable SSH password authentication.CONFIGURATION modeip ssh password-authentication enableExample of Enabling SSH Password AuthenticationTo view your SSH configuration, use the show ip ssh command from EXEC Privilege mode.Dell(conf)#ip ssh server enableDell(conf)#ip ssh password-authentication enableDell# show ip sshSSH server : enabled.SSH server version : v1 and v2.SSH server vrf : default.SSH server ciphers : 3des-cbc,aes128-cbc,aes192-cbc,aes256-cbc,aes128-ctr,aes192-ctr,aes256-ctr.SSH server macs : hmac-md5,hmac-md5-96,hmac-sha1,hmac-sha1-96,hmac-sha2-256,hmac-sha2-256-96.SSH server kex algorithms : diffie-hellman-group-exchange-sha1,diffie-hellman-group1-sha1,diffie-hellman-group14-sha1.Password Authentication : enabled.Hostbased Authentication : disabled.RSA Authentication : disabled.Vty Encryption HMAC Remote IPUsing RSA Authentication of SSHThe following procedure authenticates an SSH client based on an RSA key using RSA authentication. Thismethod uses SSH version 2.1. On the SSH client (Unix machine), generate an RSA key, as shown in the following example.2. Copy the public key id_rsa.pub to the Dell Networking system.794 Security
