Secure Shell Authentication

Secure Shell (SSH) is enabled by default using the SSH Password Authentication method.
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 configuration, use the show ip ssh command from EXEC Privilege mode.
Dell(conf)#ip ssh server enable
Dell(conf)#ip ssh password-authentication enable
Dell# show ip ssh
