Enter configuration commands, one per line.  End with CNTL/Z.

Router(config)#hostname jinyan

jinyan(config)#ip domain-name jinyan.com

jinyan(config)#crypto key ge

jinyan(config)#crypto key generate rsa

The name for the keys will be: jinyan.jinyan.com

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]

 

jinyan(config)#ip ssh time-out 60

*?? 1 0:1:7.740:  RSA key size needs to be at least 768 bits for ssh version 2

*?? 1 0:1:7.740:  %SSH-5-ENABLED: SSH 1.5 has been enabled

jinyan(config)#ip ssh au

jinyan(config)#ip ssh authentication-retries 2

jinyan(config)#line vty 0 15

jinyan(config-line)#transport input ssh

jinyan(config-line)#
