Ddclient not updating
You can tell ddclient to use this method by using this line: to ignore IP addresses before the string "foo" if necessary..Remember how I said anyone with your dynamic dns password can change your DNS records?I recently set up a backup server on an internet connection that has a dynamic IP address.So far, I've been spoiled at home because my ISP (Plus Net) makes switching to a static IP address easy and cheap, so obviously I did that.Now you have everything you need to configure ddclient.
Use this command to install ddclient: If you're not using namecheap, then this section will be different, but the concept is the same regardless of DNS provider.
To start the daemon we need to open another configuration file, to check its status.
ddclient keeps a cache of your IP address, and it will only update the record with your dynamic DNS provider if your IP address hasn't changed.
This time though, I didn't have that option, and I didn't want to configure a dynamic dns client on that router either, so I had to set it up on the server itself.
Some DNS providers offer their own dynamic DNS clients, but most of them are proprietary.
