Configuring Host-Based SSH Authentication

Authenticate a particular host. This method uses SSH version 2.

To configure host-based authentication, use the following commands.
  1. Configure RSA Authentication. Refer to Using RSA Authentication of SSH.
  2. Create shosts by copying the public RSA key to the file shosts in the directory .ssh, and write the IP address of the host to the file.
    cp /etc/ssh/ssh_host_rsa_key.pub /.ssh/shosts
    Refer to the first example.
  3. Create a list of IP addresses and usernames that are permitted to SSH in a file called rhosts.
    Refer to the second example.
  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

Examples of Creating shosts and rhosts

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.
