Last Updated : 26 Apr, 2024 Comments Improve Suggest changes Like Article Like Report User authentication authorizes a human-to-machine transfer of credentials during network interactions to verify a user's authenticity. This process checks the identification of a user trying to access a network or computational resource. We are going to perform user authentication on SSH by providing different usernames with their respective passwords. SSH stands for Secure Shell, a cryptographic network protocol for operating network services securely over an unsecured network. It is used for remote login and remote CLI access. Consider the topology: In this topology we have 3 PCs connected to a switch and that switch is connected to a router in such a manner that is given below; R1's configuration: Go to Router 1 and do the following configuration int g0/0/0 ip add 192.168.1.1 255.255.255.0 no shutdown enable password cisco ip domain-name R1 crypto key generate rsa line vty 0 4 transport input ssh login local exit username jake password Cisco username mike password CCNA username guey password CCNPPC4 configuration: Go to PC4 and do the following configuration PC5 configuration: Go to PC5 and do the following configuration PC6 configuration: Go to PC6 and do the following configuration SSH on R1 using PC4:ssh -l jake 192.168.1.1Checking the changes on R1:As you can see, the hostname of R1 has changed to R2.
