Router(config)#hostname alexrouter
alexrouter(config)#ip domain-name
alexrouter(config)#ip ssh time-out 30
alexrouter(config)#ip ssh authentication-retries 3
alexrouter(config)#ip ssh version 2
Please create RSA keys (of at least 768 bits size) to enable SSH v2.
alexrouter(config)#crypto key generate rsa
The name for the keys will be:
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]: 512
% Generating 512 bit RSA keys, keys will be non-exportable…[OK]
*Mar 1 0:1:26.828: RSA key size needs to be at least 768 bits for ssh version 2
*Mar 1 0:1:26.828: %SSH-5-ENABLED: SSH 1.5 has bee
