Example of Configuring a Cipher List
The following example shows you how to configure a cipher list.
DellEMC(conf)#ip ssh server cipher 3des-cbc aes128-cbc aes128-ctr
Configuring DNS in the SSH Server
Dell EMC Networking provides support to enable the DNS in SSH server configuration for host-based authentication. You can
specify whether the SSH Server should look up the remote host name and check whether the resolved host name for the
remote IP address maps to the same IP address. By default, the DNS in the SSH server configuration is disabled.
To enable the DNS in the SSH server configuration, use the following command.
Enable the DNS in the SSH server configuration.
CONFIGURATION mode
[no] ip ssh server dns enable
To disable the DNS in the SSH server configuration, use the no version of this command.
To view the status of DNS in the SSH server configuration, use the show running-config ip ssh command from EXEC
mode.
DellEMC#show running-config ip ssh
!
ip ssh server dns enable
ip ssh hostbased-authentication enable
no ip ssh password-authentication enable
ip ssh server enable
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 EMC Networking system. This
setup is the simplest method of authentication and uses SSH version 2.
To enable SSH password authentication, use the following command.
Enable SSH password authentication.
CONFIGURATION mode
ip ssh password-authentication enable
To view your SSH configuration, use the show ip ssh command from EXEC Privilege mode.
DellEMC(conf)#ip ssh server enable
DellEMC(conf)#ip ssh password-authentication enable
DellEMC# show ip ssh
