White Papers

• ip ssh pub-key-file: specify the le the host-based authentication uses.
• ip ssh rhostsfile: specify the rhost le the host-based authorization uses.
• ip ssh rsa-authentication enable: enable RSA authentication for the SSHv2 server.
• ip ssh rsa-authentication: add keys for the RSA authentication.
• show crypto: display the public part of the SSH host-keys.
• show ip ssh client-pub-keys: display the client public keys used in host-based authentication.
• show ip ssh rsa-authentication: display the authorized-keys for the RSA authentication.
The following example shows the use of SCP and SSH to copy a software image from one switch running SSH server on UDP port 99 to
the local switch.
Dell#copy scp: flash:
Address or name of remote host []: 10.10.10.1
Port number of the server [22]: 99
Source file name []: test.cfg
User name to login remote host: admin
Password to login remote host:
Secure Shell Authentication
Secure Shell (SSH) is disabled by default.
Enable SSH using the ip ssh server enable command.
SSH supports three methods of authentication:
• Enabling SSH Authentication by Password
• Using RSA Authentication of SSH
• Conguring Host-Based SSH Authentication
• Using Client-Based SSH Authentication
Important Points to Remember
• If you enable more than one method, the order in which the methods are preferred is based on the ssh_cong le on the Unix machine.
• When you enable all the three authentication methods, password authentication is the backup method when the RSA method fails.
• The les known_hosts and known_hosts2 are generated when a user tries to SSH using version 1 or version 2, respectively.
Enabling SSH Authentication by Password
Authenticate an SSH client by prompting for a password when attempting to connect to the Dell Networking system. This setup is the
simplest method of authentication and uses SSH version 1.
To enable SSH password authentication, use the following command.
• Enable SSH password authentication.
CONFIGURATION mode
ip ssh password-authentication enable
Example of Enabling SSH Password Authentication
To view your SSH conguration, use the show ip ssh command from EXEC Privilege mode.
Dell(conf)#ip ssh server enable
% Please wait while SSH Daemon initializes ... done.
Dell(conf)#ip ssh password-authentication enable
Dell#sh ip ssh
SSH server : enabled.
