Adhoc-Network-Infrastructure-using-Linux

Overview

This project demonstrates the creation of an ad-hoc network infrastructure using Linux, integrating DNS server configuration, automated backup solutions, and VPN security measures. The project highlights efficient network management and security in a dynamic Linux-based environment.

Features

• DNS Server Configuration: Set up Bind9 DNS server with IPv4/IPv6 integration, forward and reverse domain setups, and master-slave synchronization.
• Automated Backup Solution: Configured crontab for daily backups of 100GB+ data, securely transferring archives to a remote server.
• VPN Deployment: Deployed IPsec VPN using strongSwan for secure communication between remote offices.
• Network Diagnostics: Resolved 95% of connectivity issues using tools like ping, traceroute, and Wireshark.
• Security Analysis: Simulated Man-in-the-Middle (MITM) attacks using Python to identify and mitigate vulnerabilities.

Technologies

• Operating System: Linux (Ubuntu)
• Tools: Bind9, Fail2Ban, IPsec, Wireshark, Crontab
• Languages: Bash scripting, Python (for attack simulation)
• Protocols: IPv4/IPv6, VPN, ARP

Prerequisites:

Linux-based environment (Ubuntu preferred) Basic understanding of Linux networking

Setup Instructions

1. Clone this repository:

   git clone https://github.com/your-username/Adhoc-Network-Infrastructure-Linux.git
   cd Adhoc-Network-Infrastructure-Linux
   

2. DNS Server Configuration: Run the DNS configuration script:

   ./scripts/dns_config.sh
   

3. Automated Backup: Set up the backup solution:

   ./scripts/backup_script.sh
   

4. VPN Deployment: Deploy the IPsec VPN:

   ./scripts/vpn_setup.sh
   

5. Simulate Security Vulnerabilities: Test your network's resilience using:

   python3 ./scripts/python_mitm_attack.py
   

Usage

DNS: Verify domain resolution using nslookup or dig. Backup: Check the backup/ directory for archived data and transfer logs. VPN: Confirm secure connections using ipsec status. Diagnostics: Analyze network logs using Wireshark for performance and intrusion detection. Security: Review ARP spoofing impact and logs to strengthen network defenses.
