A service to check the IP address that points to the current machine, and update Cloudflare's DDNS system with our domain name.

Requirements

• GCC or Clang
• Libcurl
• Libjson-c
• CMake 3.0+
• Systemd (optional)

Building

git clone https://github.com/camrockz/Cloudflare-DDNS-Updater.git
mkdir build
cd /build

With systemd support

cmake .. -DCMAKE_BUILD_TYPE=release -DSYSTEMD=ON
make

Without systemd support

cmake .. -DCMAKE_BUILD_TYPE=release -DSYSTEMD=OFF
make

Install and Run

In a root user shell

cp ipup /usr/bin/
mkdir /etc/ipup
cp ../ipup.conf /etc/ipup/
chown root:root /usr/bin/ipup /etc/ipup/ipup.conf

Now edit /etc/ipup/ipup.conf with your cloudflare settings

For systemd use

cp ../ipup.service /usr/lib/systemd/system/
systemctl enable ipup
systemctl start ipup

For init systems other than systemd, install a startup script for the ipup executable as per instructions for your init system.
