This is a bash script to act as a Cloudflare DDNS client, useful replacement for ddclient.

How to use?

1. Put the cfupdater files to /usr/local/bin

• If you are using IPv4 for A record, append -v4 to cfupdater in the following systemd service unit.
• If you are using IPv6 for AAAA record, append -v6 to cfupdater in the following systemd service unit.
• If you prefer a dual-stack record, append -dualstack to cfupdater in the following systemd service unit.

2. chmod +x /usr/local/bin/cfupdater
3. Create a systemd service unit at /etc/systemd/system/, the cfupdate.service is shown as an example.
