Configuration considerations
In the server configuration, the client public key is required. Use the client software to generate the RSA
key pair on the client before configuring the Stelnet server.
The device supports a variety of Stelnet client software, such as PuTTY, and OpenSSH. The following
example takes PuTTY Version 0.58 on the Stelnet client.
Configuration procedure
1. Generate an RSA key pair on the Stelnet client:
a. Launch PuTTYGen.exe, select SSH-2 RSA and click Generate.
When the generator is generating the key pair, you must move the mouse continuously and
keep the mouse off the green progress bar shown in Figure 111. Otherwise, the progress bar
stops movin
g and the key pair generating progress stops.
