 Choose the proper SSH version. Generally the client provides several SSH

versions. V1.20 supports SSH Server 1.5, so you must choose 1.5 or lower.

 Specify the RSA key file. If you have configured to choose RSA authentication at

the server, you must specify the RSA key file at the client. In normal case, RSA

key file is created by the tool attached to the client software, including a pair of

public key used for the server (router) and private key used for the client.

Use the third party client software, PuTTY in the following example, to set the

configuration of SSH client.

I. Specify the IP address of the server

Enable the PuTTY program and the following client configuration interface appears.

Figure 3-1 SSH Client configuration interface (1)

Enter the IP address of the router in the field “Host Name (or IP address)”. The

address can be the IP address of the interface whose protocol status is “up” on any

router, but the route to the SSH client can be reachable, for example , 10.110.28.10.

II. Set the remote connection protocol to SSH

Choose "SSH” as the protocol in the above interface.
