What are the common pitfalls when setting up Cloudflare DDNS on Linux and how can I avoid them?

Common pitfalls include: incorrect API token permissions, incorrect DNS record type (usually A record), rate limiting by Cloudflare API, and script execution errors. Avoid them by: 1) Ensuring the API token has appropriate permissions (DNS Edit). 2) Verifying the DNS record type matches your setup. 3) Implementing error handling and rate limiting in your script. 4) Logging script execution and monitoring for failures.
