A.4 Preparing access via SSH
To access the device through an SSH, follow the steps below:
Generate a key (SSH Host Key).
Install the key on the device.
Enable access through an SSH on the device.
Install a program that runs the SSH protocol (SSH client) on your
computer.
A.4.1 Generating a key
One way of generating a key is with the PuTTYgen program. This program is
provided on the product-CD.
Start the program by double-clicking on it.
In the main program window in the "Parameters" box, select the type
"SSH-1 (RSA)".
In the "Actions" box, click on "Generate". Move the mouse pointer over the
PuTTYgen-window, so that PuTTYgen can create the key using random
numbers.
Leave the "Key passphrase" and "Confirm passphrase" input boxes
empty.
In the "Actions" box, click on "Save private key".
Click "Yes" to answer the question whether you want to save the key
without a passphrase.
Select the Save location and enter a file name for the key file.
Note down the key fingerprint, so that you can check it when establishing
a connection.
You should also store the key in a location separate from the device so
that, if the device is being replaced, the key can be transferred to the new
device.
