This method uses SSH version 1 or version 2. If the SSH port is a non-default value, use the ip ssh server port number command to change the default port number. You may only change the port number when SSH is disabled. Then use the -p option with the ssh command. • SSH from the chassis to the SSH client. ssh ip_address Example of Client-Based SSH Authentication Dell#ssh 10.16.127.201 ? -l User name option -p SSH server port option (default 22) -v SSH protocol version Troubleshooting SSH To troubleshoot SSH, use the following information. You may not bind id_rsa.pub to RSA authentication while logged in via the console. In this case, this message displays:%Error: No username set for this term. Enable host-based authentication on the server (Dell Networking system) and the client (Unix machine). The following message appears if you attempt to log in via SSH and host-based is disabled on the client. In this case, verify that host-based authentication is set to "Yes" in the file ssh_config (root permission is required to edit this file): permission denied (host based). If the IP address in the RSA key does not match the IP address from which you attempt to log in, the following message appears. In this case, verify that the name and IP address of the client is contained in the file /etc/hosts: RSA Authentication Error. Security 935
