8.2.20 ssh
8.2.20.1 ssh enable
This command enables the ssh server using the specified protocol:
z SSH connection is disabled by default.
z An operation command must be used to create a key file before SSH is enabled.
z User authentication supports only password authentication (the client side does not
have the public key).
z The supported SSH protocol versions are RSA Version1, RSA Version2, and DSA
Version2.
z If no parameter is specified in the ssh enable command, all authentication methods
of rsa1, rsa, and dsa are enabled.
z If the ssh enable command is executed when no key file has been created, no error
occurs, but no connection using ssh can be established. In such cases, create a key
file by executing the ssh keygen command.
z If another ssh enable command is executed after a ssh enable command, the
settings in the command executed last are used to enable ssh.
Example: If rsa1, rsa, and dsa are already enabled when the ssh enable rsa
command is executed, the server is restarted with only rsa enabled.
z A connection cannot be established from a business LAN by only executing the ssh
enable command. Setting must be made with the remote-access command to allow
connections.
z Only one connection can be established at a time.
z If ssh is disabled when a connection using ssh has been established, the connection
is not terminated.
