Client-based SSH Authentication SSH from the chassis to the SSH client using using the command ssh ip_address. This method uses SSH version 1 or version 2. If the SSH port is a non-default value, use the command ip ssh server port number, to change the default port number. You may only change the port number when SSH is disabled. When must then still use the -p option with the command ssh. FTOS#ssh 10.16.127.201 ? -l User name option -p SSH server port option (default 22) -v SSH protocol version Troubleshooting SSH • You may not bind id_rsa.pub to RSA authentication while logged in via the console. In this case, Message 2 appears. Message 2 RSA Authentication Error %Error: No username set for this term. • Host-based authentication must be enabled on the server (Dell Force10 system) and the client (Unix machine). Message 3 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). Message 3 Host-based Authentication Error 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, Message 4 appears. In this case, verify that the name and IP address of the client is contained in the file /etc/hosts. Message 4 RSA Authentication Error getname info 8 failed Telnet To use Telnet with SSH, you must first enable SSH, as described above. By default, the Telnet daemon is enabled. If you want to disable the Telnet daemon, use the following command, or disable Telnet in the startup config. Use the [no] ip telnet server enable command to enable or disable the Telnet daemon.
