I just wanted to log this great website that I found which offers a great copy and paste ddclient setup. It’s much better than the out-of-the-box setup that comes with the software. Thanks very much for this tutorial!
detailed ubuntu ddclient and namecheap tutorial
It was also interesting to learn that Namecheap simply uses a service called ‘freedns’ apparently…. good to know in case you need to change domain registrars and keep a free dynamic dns service going….
