rn104 ddclient freedns

I had a lot of difficulties setting up ddclient on my Pro. You're on a different ReadyNAS OS version, but I suspect that ddclient still is the same. One of the things I found that you do not have is that it required a final forward slash after the web=address (so web=myip.dnsomatic.com/ in your case). That is the line where it gets your IP address, so it sounds like a possibility of why you would get an error related to 'IP='. (If you point your browser to http://myip.dnsomatic.com, you will see it simply returns your IP address). I use No-IP to do that, but it shouldn't matter so long as it just returns the address (otherwise, you need a SKIP command).

But you may also have some other issues once you get that fixed. Are your user name and password properly quoted? Can't tell from the way you have made them generic.

You do realize, I hope, that *SubDomain Created on Afraid.org* needs to be replaced by the subdomain(s) or domain(s) you are trying to update. Again, hard to tell from the way you've made it generic. The domain name is not quoted.

Here is my configuration for No-IP (with user name, password, and domain name made generic):

daemon=600
ssl=yes
use=web, web=ip1.dynupdate.no-ip.com/
protocol=noip,
server=dynupdate.no-ip.com,
login='username'
password='password'
my_domain.no-ip.org

Obviously, change the server, protocol, username, password, and my_domain.no-ip.org to what's appropriate for you, but keep the quoting just as shown. Note, too, the placement of commas at the ends of some lines. Some may not be required, but this definitely works for me and I didn't bother to find if any could be eliminated. Hopefully, with a couple changes for freedns, it'll work for you.

You can also debug whether it is working if you have SSH access, using the following command string:

sudo ddclient -daemon=0 -debug -verbose -noquiet

That was what helped me finally figure out it was not retrieving my IP address properly from the web server.
