Cloudflare DDNS for Padavan

The cloudflare_ddns.sh is a command-line tool for Cloudflare DDNS (Dynamic Domain Name Server). It is written in the shell and has very few dependencies.

Usage:

1. Download the shell script then upload it to a folder on your Padavan router, e.g. /usr/bin.
2. Give the shell script executable permissions.

chmod +x /usr/bin/cloudflare_ddns.sh

3. Modify the variables in the shell script according to the comments.
4. Run the shell script and view the results.
5. After confirming that it is correct, you can also add it to the crontab for automatic execution.

# e.g.
# Run every five minutes
*/5 * * * * /usr/bin/cloudflare_ddns.sh > /dev/null 2>&1
