Enabling SSH access on a router in Packet Tracer

In this article, I describe the steps for Enabling SSH access on a router in Packet Tracer. Enabling SSH access on a router in Packet Tracer involves several steps. SSH (Secure Shell) provides a secure way to access and manage network devices remotely. Here are the steps for Enabling SSH access on a router in Packet Tracer:

Access Router CLI:

• Launch Packet Tracer and open the network topology where the router is located.
• Double-click the router icon to open the Command Line Interface (CLI) of the router.

Configure a Hostname:

• Enter privileged exec mode by typing enable and then entering the enable password if configured.
• Configure a hostname for the router using the hostname command. For example, hostname Router1.

Generate Encryption Keys:

• Encryption keys are necessary for secure SSH communication. Generate them using the following commands:
  crypto key generate rsa usage-keys label ssh-key modulus 2048
  This command generates a 2048-bit RSA key pair for SSH.

Configure the VTY Lines:

• Enter global configuration mode by typing configure terminal.
• Access the VTY (Virtual Terminal) lines configuration using the following command:
  line vty 0 15
  This command accesses all the VTY lines from 0 to 15.

Enable SSH Login:

• To allow SSH access only, disable Telnet by using the transport input command:
  transport input ssh

Set a Login Local Authentication Method:

• Configure the router to use the local username and password for authentication. You can create a local username and password pair with the following commands:
  login local username user1 secret pass@1234
  Replace <username> and <password> with your desired username and password.

Exit Configuration Mode:

• Exit VTY line configuration mode and global configuration mode by typing exit twice.

Save Configuration:

• Save the configuration to the router’s startup configuration file to persist the changes across reboots:
  write memory

Testing SSH Access:

• From a remote device (PC or another router) with SSH client software, attempt to connect to the router’s IP address. Use the configured username and password when prompted.

That’s it! You have now enabled SSH access for remote management on the router in Packet Tracer. Remember to use username user1 and password pass@1234 with your actual values, and ensure that the router’s interfaces are properly configured and reachable from the network you are connecting from.
