Bash Network Information Collector

A Bash script for collecting network and system information from a Linux system and generating a text report.

Overview

This script collects useful information about the system's network configuration, hardware, routing, DNS, firewall, kernel modules, and network settings.

The collected information is saved in a timestamped .txt file.

The script is mainly intended for:

• Linux network diagnostics
• System administration
• Network troubleshooting
• Bash scripting practice
• Collecting system information for technical support

Requirements

The script is designed for modern Linux distributions such as Pop!_OS and Ubuntu.

The script uses common Linux commands:

• ip - Network interfaces and routing
• ss - Network connections and statistics
• nft - Firewall rules
• lspci - PCI hardware information
• lsb_release - Linux distribution information
• hostname - System hostname
• uname - Kernel information
• cat - Read configuration files
• date - Generate the report date

Root privileges are required because some network and firewall information can only be accessed by the root user.

Usage

Give the script execution permission:

chmod +x network_info.sh
