  1. PODynDNS and the incontrovertible badauth response
    text
    copied!<p>I'm trying to use the DynDNS API to validate user-supplied DynDNS credentials, and <a href="http://dyn.com/support/developers/api/perform-update/" rel="nofollow">the documentation</a> says that <a href="http://dyn.com/support/developers/api/return-codes/" rel="nofollow">the 'badauth' response</a> is meant for exactly that.<br> The idea being that I can automate an update with the user credentials and look for the badauth response and use that to detect incorrect credentials, which sounds perfect.<br> The problem is that the only response I ever get is badauth. When I send credentials that should be good (since they're currently working for login and all) I get a badauth response. Here's my code:</p> <pre><code> try { string target = string.Format( "http://{0}:{1}@members.dyndns.org:8245/nic/update?hostname={2}&amp;myip={3}", HttpUtility.UrlEncode( DynDnsUserName ), HttpUtility.UrlEncode( DynDnsPassword ), HttpUtility.UrlEncode( DynDnsURL ), ip ); HttpWebRequest request = WebRequest.Create( target ) as HttpWebRequest; request.Method = "GET"; request.UserAgent = company + " - " + model + " - " + firmware; HttpWebResponse response = request.GetResponse() as HttpWebResponse; Stream reply = response.GetResponseStream(); StreamReader readReply = new StreamReader( reply ); string returnCode = readReply.ReadToEnd(); Trace.WriteLine( "We've validated the provided DynDNS credentials, response received: " + returnCode ); return !returnCode.Contains( "badauth" ); } catch (WebException webEx) { Trace.WriteLine( "WebException thrown: " + webEx.Message ); if (webEx.Response != null) { Stream reply = webEx.Response.GetResponseStream(); StreamReader readReply = new StreamReader( reply ); Trace.WriteLine( "Actual response: " + readReply.ReadToEnd() ); } } </code></pre> <p>No matter the credentials I use, I keep getting a thrown WebException "Remote server returned an error: (401) Unauthorized" with a response body of badauth. Any ideas? </p>
