# Network Connection Tester (v1.0.0)
Developed by Emmanuel Hernandez | Automation Specialist II

A high-performance CLI tool designed to monitor network devices in real-time using parallel processing (up to 30 workers). It verifies ICMP reachability (Ping) and TCP port status, exporting a historical log to a timestamped CSV on exit.
## Project Structure
* `src/cli.py`: Main execution script for the terminal interface.
* `devices_example.csv`: Template file for targets input.
## How to Run
1. Download the latest version from the **Releases** section.  
2. Use `devices_example.csv` as a template to create a list of devices to be tested.
3. Using **File Explorer**, drag and drop your CSV file onto `Network_Scanner.exe` to execute the tool.
4. Once the tool opens, you will see a live table updating the status of your devices in real-time.
5. Press `Ctrl + C` to stop the execution and automatically generate the results report.
6. Press `Enter` to close the window.
## How to Run .exe from Terminal (PowerShell / CMD)
If you prefer to run the executable using command lines instead of dragging files:
1. Open PowerShell or CMD and navigate to the folder where `Network_Scanner.exe` and your CSV file are located.
2. Execute the `.exe` by passing your CSV file as an argument:
   ```powershell
   .\Network_Scanner.exe your_devices_file.csv
## How to Run from Terminal (Development)
1. Ensure you have Python installed and your virtual environment active.
2. Install the required dependencies:
   ```bash
   pip install -r requirements.txt
3. Execute the tool by providing your target CSV file:
   ```Bash
   python src/cli.py csv_file_name.csv
