show ssh server
Arguments
enable <0 / 1>
The value of 0 disables SSH and the value of 1 enables SSH. The default value is 1 since SSH is
enabled by default.

SSH Authentication Methods

You can perform the SSH authentication in the following ways:
Password authentication—set up by default. In this method, you can connect to the SSH
server running on IP40 from the SSH client installed on your computer, after entering your
password.
Public-key authentication—one of the most secure ways to authenticate by using SSH.
The basic principle in public-key authentication is the use of a pair of computer-generated
keys: private key and public key. A public key is not useful unless you have the
corresponding private key.

Using SSH Client

You need an SSH client to connect to the SSH server running on IP40. Install an SSH client if
you do not have one already.
You can use the SSH client to connect to the IP40 by using password authentication or public
key authentication. For additional information, see User Manual of the SSH client you are using.

Configuring Advanced Secure Shell Server Options

For additional information on using the command line options, see the Nokia IP40 Security
Platform CLI Reference Guide Version 1.1.
