DNS, TELNET AND SSH Simulation for Name Resolution and Remote Access | Cisco Packet Tracer (2025)
In this video, I demonstrate a DNS, Telnet, and SSH simulation using Cisco Packet Tracer.
The objective of this project is to explain how DNS enables hostname-based access and how remote access to a router can be performed using Telnet (insecure) and SSH (secure).
The video covers the complete step-by-step implementation, starting from network topology creation to testing Telnet and SSH connectivity using DNS name resolution.
🔹 Topics Covered in This Video:
Network topology creation using PCs, Switch, Router, and Server
Cable connections using copper straight-through cables
Static IP address configuration for all devices
DNS Server configuration and hostname mapping
Router basic configuration using CLI
Telnet configuration and testing
SSH configuration using RSA keys
Comparison between Telnet and SSH
🔹 Tools & Technologies Used:
Cisco Packet Tracer
DNS (Domain Name System)
Telnet
SSH (Secure Shell)
🔹 Learning Outcomes:
Understanding DNS name resolution
Understanding remote router management
Differentiating between secure and insecure protocols
Practical exposure to Cisco IOS commands
This project is useful for students learning Computer Networks, Cisco Packet Tracer, and basic network security concepts.
