d. Verify that the passwords are encrypted.

password 7 0822455D0A16

login

S1(config)#ip domain-name netacad.pka

b. Secure keys are needed to encrypt the data. Generate the RSA keys using a 1024 key length.

% Generating 1024 bit RSA keys, keys will be non-exportable...[OK]

Create an SSH user and reconfigure the VTY lines for SSH-only access.

S1(config)#line vty 0 15
S1(config-line)#login local
S1(config-line)#transport input ssh
S1(config-line)#no password cisco
