SSH Configurration

SSH (Secure Shell) is one of the most used protocols in network World. As a secured alternative of Telnet, SSH is always in the life of a network engineer. It helps us to connect our routers, swithces and any other network equipments. Especially because of SSH is more secure, it is always prefered more than Telnet. In this lesson, we will focus on SSH Configuration on Cisco routers with an SSH Config Example.

So, what will be our SSH Config steps? In this example, we will go through the below six steps one by one:

- IP Configs
- Password Encryption
- Domain Data Encryption
- Router User Config
- SSH Config
- SSH Verification

So, let’s start our Configuration and see how is the backplane config of our SSH connection on routers.

The main configuration step of this SSH Config lesson is this step. Here, we will do the SSH configuration in line mode.

Firstly, we will go to line mode and configure the ssh for 17 users from 0 to 16. And then we will use “transport input ssh”. This command will allow only SSH access. Telnet accesses will be rejected.

Then, we will set the login as local with “login local” command. With this command, we can use local router users to ssh access.

After that , we will configure the the version of SSH. There are two SSH versions, SSH version 1 and SSH version 2. The second one provide more enhanced security agorithm. Here, we will use SSH version 2. Ton configure it, we will use “ip ssh version 2” command.

Lastly, we will save our SSH Configuration.

Router (config) # line vty 0 16
Router (config-line) # transport input ssh

Router (config-line) # login local
Router (config-line) # ip ssh version 2
Router (config-line) # end
Router # write

SSH Verification

At the last step of SSH Configuration in Cisco PAcket Tracer, we can try to connect via SSH from PC to the router. Do do this, we will open the command line on the PC and connect to the router with the below command. Here our Router interface ip is 10.0.0.1.

ssh –l gokhan 10.0.0.1
