The final step is to test the connectivity of ssh from PC1 with “ ssh -l Admin 192.168.1.1” command for command prompt. Related Article: Install SSH on CentOS 8.x and Red Hat Linux Finally set the ssh timeout to 120 seconds with “ IP ssh time-out 120” command.Configure ssh to version 2 using “ IP ssh version 2” and set the authentication times to 3 with “ IP ssh authentication-retries 3” command.Configure the router to accept only ssh connection with “ transport input ssh” command.But here we configure ssh to use local username and password. Remember that you can set a username and password for ssh with “ username Admin password Technig” command as well. Configure ssh to use local username and password with “ login local” command.Enabled ssh with “ line vty 0 4” command.Add username “ Admin” with Password of “ Technig” for ssh authentication.Then configure the router to use RSA key pair with modulus size of 1024 bites for remote service authentication with “ crypto key generate rsa ” command.Termius uses end-to-end encryption to ensure your data remains safe and secure. This data, along with connection and command history, is securely synced across all your devices. Groups allow you to share settings, though each host can have its own separate preferences. I have set DNS domain name with “ IP domain-name” command. Termius lets you organize hosts into groups.R1(config)#ip ssh authentication-retries 3 R1(config)#username Admin password Technig % Generating 1024 bit RSA keys, keys will be non-exportable. Choosing a key modulus greater than 512 may take The name for the keys will be: R1.Ĭhoose the size of the key modulus in the range of 360 to 2048 for your R1>Įnter configuration commands, one per line. It’s enough to learn how to configure SSH on Cisco router. In this example, I just enable and configure SSH on SW1 and trying to access it from PC1. Configure SSH on Cisco Router or Switch – Technig Just try to learn and do it what the SSH remote authentication needs.ĭownload the packet tracer lab or create your own lab. The configure on a packet tracer lab and real Cisco devices are the same. Let’s enable and configure SSH on Cisco router or switch using the below packet tracer lab. To configure SSH on Cisco router, you need to do: managing network infrastructure and other mission-critical system components.interactive and automated file transfers.If the destination device is not configured with the same user name as the source than you can add the use name to the string. 10.10.10.1 is the IP address of the device you want to connect to. providing secure access for users and automated processes Use can use the same method for both the switch and the router: ssh 10.10.10.1.The protocol is used in corporate networks for: The protocol specification distinguishes between two major versions, referred to as SSH-1 and SSH-2. Common applications include remote command-line login and remote command execution, but any network service can be secured with SSH. SSH provides a secure channel over an unsecured network in a client-server architecture, connecting an SSH client application with an SSH server. The best-known example application is for remote login to computer systems by users. The Secure Shell (SSH) is a cryptographic network protocol for operating network services securely over an unsecured network. Allow only SSH access on VTY lines using command “ transport input ssh”.Short and complete guide to configure SSH on Cisco router and switch for secure remote connection.Create a user in the local database using command “ username…secret”.Generate public and private keys using command “ crypto key generate rsa”.Configure the domain name using command “ ip domain-name”.Configure the router hostname using command “ hostname”.It is a secure alternative to the non-protected login protocols (such as Telnet) and insecure file transfer methods(such as FTP). On the contrary, SSH2 is a much more secured, an efficient version of SSH that includes SFTP, which is functionally similar to FTP with addition of SSH2 encryption. It also provides secure encrypted communications over the Internet. It provides strong host-to-host and user authentication. SSH v1 (Secure Shell) provides an encrypted channel to users for logging into remote device.
