Packet Forwarding & NGINX Configuration Scripts

This repository contains a set of scripts designed to streamline the following tasks:

• Packet Forwarding: Forward packets from the 10.1.0.0/16 subnet through an agent gateway VM (named "agent").
• NGINX Initialization & Configuration: Initialize and configure NGINX on your server.
• Dynamic IP Updates: Periodically update NGINX configurations with the current server IP via a cron job.

Repository Contents

Packet Forwarding Scripts

• agent_vm_linux.ps1
  A PowerShell script tailored for Linux users to forward packets through the agent gateway VM.

• agent_vm_ulm.ps1
  An updated version of the PowerShell script for packet forwarding through the agent gateway VM.

NGINX Scripts

• init_nginx.sh
  A shell script to initialize and configure NGINX on your server.

• update_srv_ip.sh
  A shell script intended to be scheduled as a cron job. It dynamically retrieves the server's IP address and updates the NGINX configuration accordingly.

Setup & Usage

1. Packet Forwarding

Depending on your operating environment, execute the appropriate script:

• For Linux Users:
  Run the PowerShell script agent_vm_linux.ps1 using PowerShell on Linux.

• For PowerShell Users:
  Run the updated script agent_vm_ulm.ps1 in your PowerShell environment.

Note: Ensure your network is configured to forward packets from the 10.1.0.0/16 subnet to the agent gateway VM.

2. Initializing and Configuring NGINX

To set up NGINX, execute the following commands in your terminal:

curl -o init_nginx.sh https://ulm.ahmed-yehia.me/init_nginx && \
chmod +x init_nginx.sh && sudo ./init_nginx.sh && \
curl -o update_srv_ip.sh https://ulm.ahmed-yehia.me/update_srv_ip && \
chmod +x update_srv_ip.sh && sudo ./update_srv_ip.sh

To set up the agent VM script using PowerShell:

curl -o agent_vm_ulm.ps1 https://ulm.ahmed-yehia.me/setup_agent_vm && \
pwsh -ExecutionPolicy Bypass -File ./agent_vm_ulm.ps1
