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