Re: [ferret_users] opendap access

hi Carol and Nuncio,
Thank you for the report.  We've reported this to Unidata.

Hi Ansley,
This is the same problem that I ran into (we had an email exchange about it at the beginning of 2011).  That command works for Ferret v6.3 but not v6.65.  My solution (so far) has been just to use Ferret v6.3.

Hi -
The error message is coming from the netCDF/Opendap library which Ferret uses to access OPeNDAP URL's.  Ferret simply passes the entire URL string to the library, which tries to open the dataset, and if it encounters an error, passes the error back to Ferret.  It's saying that the username/password credentials aren't recognized.  The question needs to be addressed to the data provider at Aviso.

  HI All,

I tried to connect to the opendap using ferret by the following command
  use "http://aviso-users:grid2010@xxxxxxxxxxxxxxxxxxxxxxxxxx/thredds/dodsC/dataset-duacs-dt-upd-global-merged-msla-h"
but resulted in the following error

" syntax error, unexpected SCAN_WORD, expecting SCAN_ATTR or SCAN_DATASET or SCAN_ERROR

How to get around this problem
