CCNA – Habilitando SSH

Vamos a configurar el acceso administrativo por SSH. Los pasos son:

1. Crear el dominio
2. Generar las claves
3. Habilitar ssh en vty

SW3>en
SW3#conf t
Enter configuration commands, one per line. End with CNTL/Z.
SW3(config)#
SW3(config)#
SW3(config)#user
SW3(config)#username melin secret cisco
SW3(config)#ip domain-name melin360
SW3(config)#crypto key generate rsa
The name for the keys will be: SW3.melin360
Choose the size of the key modulus in the range of 360 to 2048 for your
General Purpose Keys. Choosing a key modulus greater than 512 may take
a few minutes.

How many bits in the modulus [512]: 2048
% Generating 2048 bit RSA keys, keys will be non-exportable…[OK]

SW3(config)#line vty 0 15

SW3(config-line)#transport input ssh
SW3(config-line)#exit
SW3(config)#ip ssh version 2
