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
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 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
shosts and rhosts
