SSH (Secure Shell) provides secure management of network devices. By using SSH, you establish a secure connection to a network device that you access, and your data is sent in encrypted form.
Configure a domain name with the ip domain-name command followed by whatever you would like your domain name to be. I used CiscoLab.com. LabRouter(config)#ip domain-name CiscoLab.com. We generate a certificate that will be used to encrypt the SSH. May 09, 2015 This article is going to shows the CCNA students to configure and enable telnet and ssh on Cisco router and switches. The Telnet is an old and non-secure application protocol for remote control services. You can configure telnet on all Cisco switches.
How to Enable SSH in Cisco Router with Packet Tracer
SSH is a much safer protocol than the Telnet protocol and uses the TCP 22 port by default. The port number may vary.
There are 2 versions of the SSH protocol. These; Version 1 and Version 2.
SSH V1 exploits several patented encryption algorithms and is vulnerable to a well-known vulnerability that could allow an attacker to enter data into the communication flow.
SSH V2, this release has an advanced key exchange algorithm that is not vulnerable to the same abuse and includes more powerful and comprehensive features:
• Encryption such as 3DES and AES.
• Use voice encryption Message Verification Code (MAC) algorithms for integrity checking. • Support for public-key certificates.
We recommend that you use SSH V2 as far as possible to remotely manage network devices.
To enable SSH in the real scenario, make sure that the file name of your Cisco IOS software is k9 (crypto).
Step 1
First, run Packet Tracer and then create a network topology as shown in the image below. Add an additional Router to the workspace, because after configuration we will connect the Router to the Router with SSH.
Step 2
Open the CLI prompt by clicking on the SYSNETTECH Router and press Enter to skip the initial configuration.

Step 3
To enable SSH on the router, perform the following commands in order.
Step 4
Configure the IP settings of PC1 as follows.
Step 5
To quickly configure the R1’s interface, double-click on it, click the Config tab in the window that opens, and then configure the Port Status option of the GigabitEthernet0/0 interface to On, then assign the IP address.
Step 6
To test whether SSH is running, open the PC1 prompt and establish a connection using the command below.
Step 7
Enter the user name and password you created, and as soon as you press Enter, the connection will be established as in the image below.
Step 8
After executing the show ssh command on PC1 Command Prompt, you can check the version of the SSH protocol that is linked.
Step 9
In this step, execute the following command to make SSH from router to router.
Step 10
In the same way, enter the user account information you created on the Cisco Router and press Enter.

Step 11
As you can see in the image below, a successful SSH connection is made.

In this article, after examining how to enable SSH, we have connected with SSH from PC to Router and Router to Router to verify the connection. In the real scenario, to configure SSH on Routers, make sure the IOS image has k9 (crypto). Thanks for following us!
