I have been trying to get DDNS working to update a host using dnsomatic or custom and not had any success. The DDNS provider that I am currently working with is NameCheap. The error that is reported is “Authentication Error”. It also reports the same error when I try and use dnsomatic for a single host … it does however work if I tell it to use the all.dnsomatic.com host which updates everything on the account. Things that I have noticed:
-the url field actually seems to want a server not really a url because if you supply a properly formated url the GUI will not allow you to save it.
-the host field seems to want a fqdn and will not permit you to use a host unless it contains a “.”. To get around this I made my host in a subdomain so that it would have a dot (ex. pep1.NYC, and pep2.LAX).
I would really appreciate if someone could let me know the key to getting this to work correctly.
