Configuration procedure
In the server configuration, the client's host public key is required. Use the client software to generate RSA
key pairs on the client before configuring the Stelnet server.
There are different types of Stelnet client software, such as PuTTY, and OpenSSH. This example uses an
Stelnet client that runs PuTTY version 0.58.
The configuration procedure is as follows:
1. Generate the RSA key pairs on the Stelnet client:
a. Run PuTTYGen.exe on the client, select SSH-2 RSA and click Generate.

b. Continuously move the mouse and do not place the mouse over the green progress bar shown

Figure 52 . Otherwise, the progress bar stops moving and the key pair generating progress
stops.
