Auto IP Changer for VestaCP
Posted: Tue Aug 01, 2017 2:37 am
I made this little script that auto updates the server IP of VestaCP.
This script does not need any arguments, so it can be run on cron.
Also, this only works on configurations that have the the server IP as the public IP.
Disclaimer: I am not responsible for any damages done to your server using this program. Please use in your own risks. Also, backup before using this as this script may have bugs present.
Instructions:
First, do or login as ROOT on your server.
Second, do to create the file.
Third, do and paste the code below.
Then press Ctrl+X to end, and press y to confirm.
Lastly, to make the program executable.
Optionally, you can head over to your vesta panel to add a cron job running.
Feel free to report any bugs, and DO BACKUP BEFORE USING! Thanks!
