Network Information Script

This Bash script fetches network details (WiFi SSID, interface, IP address) and sends them to a Discord webhook. It also uploads a detailed log file and is configured to run at startup using systemd.

Features

• Collects network details using ifconfig and iwconfig.
• Sends details as a Discord embed and uploads a log file.
• Runs automatically at system startup.

Setup

Dependencies

Install required tools:

sudo apt update
sudo apt install net-tools wireless-tools curl

Script Setup

1. Place the networkinfo.sh script anywhere (e.g. /var/www/html/ for my convenience with other automations) and make it executable

   sudo chmod +x /var/www/html/networkinfo.sh

2. Replace the webhook URL in the script:

   webhook_url="https://discord.com/api/webhooks/YOUR_WEBHOOK_URL"

Configure systemd

1. Create a service file:

   sudo nano /etc/systemd/system/networkinfo.service

2. Add:

   [Unit]
   Description=Run networkinfo.sh at startup
   After=network-online.target
   Requires=network-online.target
   
   [Service]
   ExecStart=/var/www/html/networkinfo.sh
   Restart=on-failure
   
   [Install]
   WantedBy=multi-user.target

3. Enable the service:

   sudo systemctl daemon-reload
   sudo systemctl enable networkinfo.service
   sudo systemctl start networkinfo.service
