Pushbullet notifications on remote IP Change

Simple bash script that allows for Pushbullet notifications to mobile/desktop apps whenever a remote IP changes. Useful for SSHing remote home connections that have dynamically-assigned IP's. Originally made so I could manage a relatives home media server remotely, for anything else use a Dynamic DNS.

This example is with Pushbullet but you can use alternative notification services so long as they support API calls.

Usage

1. Create an account with Pushbullet
2. Install their mobile app or desktop/browser extension
3. On your remote machine, in any directory of your choosing, use:
   • wget -L https://raw.githubusercontent.com/ckbaudio/pushbullet_ip_notify/main/pb_ipcheck.sh
4. Create a token in Pushbullet
5. Paste your token inside pb_ipcheck.sh via replacing pbapi="ur_token_here"
   • Additionally, you can change the location of the ip.txt (default is script location).
6. Make the script executable: sudo chmod +x pb_ipcheck.sh
7. Create a scheduled task as root via sudo crontab -e with 0 */6 * * * ./home/usrname/pb_ipcheck.sh
   • This example will run a check every 6 hours
