[Note] SSH配置模版

SSH Server Configuration:

Router(config)# hostname ssn  
ssn(config)# ip domain-name ssn.com  
ssn(config)# crypto key generate rsa  
The name for the keys will be: ssn.ssn.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]: 1024  
% Generating 1024 bit RSA keys ...[OK]  
00:02:25: %SSH-5-ENABLED: SSH 1.5 has been enabled  
ssn(config)# username sense1 secret bigXdogYlover  
ssn(config)# username sense2 secret BIGxDOGyLOVER  
ssn(config)# access-list 1 permit 172.16.3.10  
ssn(config)# access-list 1 permit 172.16.3.11  
ssn(config)# line vty 0 4  
ssn(config-line)# login local  
ssn(config-line)# access-class 1 in  
ssn(config-line)# transport input ssh  
ssn(config-line)# transport output ssh  
ssn(config-line)# end




Verifying Your SSH Configuration:  

ssn# show ip ssh  
SSH Enabled - version 1.5
