I am trying to download a file from a url using curl:

$ curl -3 -v "https://atl1mmsget.msg.eng.t-mobile.com/mms/wapenc?location=XXXXXXXXXXX_14zbwk&rid=027"

Where the X is a digit in the phone number of the device I am testing on.

but I am running into an error:

What does the 501 not implemented error mean? How can I get around this?

  • My bet would be that it blocks based on the User-Agent, try passing a MSIE/Mozilla-like user agent with the -A option. Commented Feb 14, 2014 at 7:23
  • Hey @StephaneChazelas, i get the same response when i run curl -3 -v -A Mozilla/5.001 "https://atl1mmsget.msg.eng.t-mobile.com/mms/wapenc?location=18188257544_14zbwk&rid=027" Commented Feb 14, 2014 at 7:34
  • Have you tried eliminating the -3 from the command line? Commented Feb 14, 2014 at 7:39
  • Yes @YoMismo, I just tried that and got this error * Unknown SSL protocol error in connection to atl1mmsget.msg.eng.t-mobile.com:443 * Closing connection 0 curl: (35) Unknown SSL protocol error in connection to atl1mmsget.msg.eng.t-mobile.com:443 Commented Feb 14, 2014 at 7:42
  • Ok I tried your url on my browser and I get the exact same error. It is not a curl problem.... Do you get to that url from a previous page where you introduce some credentials? It could be a cookie problem Commented Feb 14, 2014 at 7:48

The error code is provided by the server side, not by curl. It is an HTTP error code and the description for that can be found on wikipedia:

501 Not Implemented The server either does not recognize the request method, or it lacks the ability to fulfill the request. Usually this implies future availability (e.g., a new feature of a web-service API).

You should try to get access to the functionality with a real browser, to make sure this works (the url you provided doesn't work in my browser). Once that works you can try deleting any cookies to see if accessing the page depends on any of that. You might have to go for something like using selenium if you want to automate accessing that page.

  • That sounds pretty reasonable. The problem is I have an mms message on Android and the "content-location" is this url. That is why I am trying to fetch the url to download the content of the MMS. So what are my alternatives? Commented Feb 14, 2014 at 7:37
  • I am not able to access this url in a browser so that is why I am looking to a unix utility to download the file. Commented Feb 14, 2014 at 7:43
  • However as you indicate this is for downloading an MMS you might not be able to do this unless you can be identified as the owner of the phone where the MMS was sent to. Is the 18188257544 part of your phone number? Have you ever tried to do this via a normal browser, it might ask you to identify, or identify you use this from a t-online connection (DSL) Commented Feb 14, 2014 at 7:44
  • yes that number is from the device that I am testing on. Have I tried to do what via a normal browser? Commented Feb 14, 2014 at 7:46
  • I am not sure, somehow t-online should check the validity of you accessing that data. The 14zbwk seems a bit minimal for that. Are you using a t-online provided internet access for this? Commented Feb 14, 2014 at 7:49
