Concept Guide

4. Copy the file shosts and rhosts to the Dell EMC Networking system.
5. Disable password authentication and RSA authentication, if configured
CONFIGURATION mode or EXEC Privilege mode
no ip ssh password-authentication or no ip ssh rsa-authentication
6. Enable host-based authentication.
CONFIGURATION mode
ip ssh hostbased-authentication enable
7. Bind shosts and rhosts to host-based authentication.
CONFIGURATION mode
ip ssh pub-key-file flash://filename or ip ssh rhostsfile flash://filename
The following example shows creating shosts.
admin@Unix_client# cd /etc/ssh
admin@Unix_client# ls
moduli sshd_config ssh_host_dsa_key.pub ssh_host_key.pub
ssh_host_rsa_key.pub ssh_config ssh_host_dsa_key ssh_host_key
ssh_host_rsa_key
admin@Unix_client# cat ssh_host_rsa_key.pub
ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAIEA8K7jLZRVfjgHJzUOmXxuIbZx/

The following example shows creating rhosts.
admin@Unix_client# ls
id_rsa id_rsa.pub rhosts shosts
admin@Unix_client# cat rhosts

Using Client-Based SSH Authentication
To SSH from the chassis to the SSH client, use the following command.
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
