SSH-related commands
8.3.14.1 ssh keygen
This command generates the RSA key/DSA key used by ssh:
z Three types of keys can be created: rsa1, rsa, dsa.
z One type of key file can be set for a server.
z If the key type specified by this command is set and the key specified by the ssh 
server is used for activation, an error occurs.
z If the user executes this command at the same time as the command is executed on 
another terminal, an error occurs.
z The time required for generating a key may be much longer depending on the 
GSWB operating status.
