BTW.
The latest stable version of netcdf-c is 4.4.1.1 and it works.
The version 4.5 has introduced the support for DAP4 and it may be has
introduce some issues.

Dear Anotnio,
Success with ncdump !!! So it works with ONLY
with netcdf-4.3.3.1. If I upgrade to the latest version it fails. So
this I can tell the support staff. Something has definitely changed in
going from netcdf-4.3.3.1 to netcdf-c-4.5.0-rc1.
Thank you for showing me the way one more time !!!!!!!!!!!!!!!!!!
Best,
Ashwin.

Dear Antonio,
Thank you so much for the effort in doing
this. I am extremely grateful given that they are so few who are
actually using this and you are somebody who has always encouraged
me to use nccopy for over a year now ! I am using netcdf-c-4.5-rc1
i.e. the latest netCDF version. I added this line to my .dodsrc
file -
HTTP.CREDENTIALS.USERPASSWORD=winash12@xxxxxxxxx:aaaaa
and I still get the same error . Yes I totally agree about the
instructions on the UCAR site. I have an open ticket with the
support netcdf and I just hope they are able to figure this one out.
I am enclosing the logs turned on with HTTP.VERBOSE. As you can
see the
* Server auth using Basic with user 'k,ŷ~'
it should say winash12@xxxxxxxxx <mailto:winash12@xxxxxxxxx>. So
it is still not picking the username from .netrc or the .dodsrc file.
Best wishes,
Ashwin.

Dear Ashwin,
I have tested and it's working depending on the netcdf library
version you are using.
With the version 4.1.3 (Ubuntu 14.04 repository package) the
only way it'sembedding the credentials in the URI:
$ ncdump -h
"https://YourUsernameUriEncoded:YourPassword@xxxxxxxxxxxx/thredds/dodsC/files/g/ds083.2/grib1/2000/2000.02/fnl_20000201_06_00.grib1
<http://YourPassword@xxxxxxxxxxxx/thredds/dodsC/files/g/ds083.2/grib1/2000/2000.02/fnl_20000201_06_00.grib1>"
For netcdf library version 4.3.3.1, compiled from source, the
embedded credentials on URI it's working.
If you create a .dodsrc on your working directory or $HOME
with your credentials
$ cat .dodsrc
HTTP.CREDENTIALS.USERPASSWORD=YourUsername:YourPassword
$ ncdump -h
"https://rda.ucar.edu/thredds/dodsC/files/g/ds083.2/grib1/2000/2000.02/fnl_20000201_06_00.grib1";
<https://rda.ucar.edu/thredds/dodsC/files/g/ds083.2/grib1/2000/2000.02/fnl_20000201_06_00.grib1>
and refering the .netrc file from your .dodsrc, both can be at
your working or $HOME directory
$ cat .netrc
machine rda.ucar.edu <http://rda.ucar.edu> login
YourUsernamepassword YourPassword
$ cat .dodsrc
HTTP.NETRC=.netrc
$ ncdump -h
"https://rda.ucar.edu/thredds/dodsC/files/g/ds083.2/grib1/2000/2000.02/fnl_20000201_06_00.grib1";
<https://rda.ucar.edu/thredds/dodsC/files/g/ds083.2/grib1/2000/2000.02/fnl_20000201_06_00.grib1>
I hope this helps.
Antonio
P.S.: The instructions on the UCAR blog about configuring
authentication are worthless with respect to the cookie
parameteres. This is because UCAR authentication service it's
not using them.

Dear Antonio,
Many thanks for giving me your .dodsrc file. I added a
couple of the lines from your .dodsrc file and tried it out and
and I still get the same error. Have you tried downloading from the
UCAR site recently ?
Best regards,
Ashwin.

Hello,
Has anybody been able to use nccopy with
redirect-based authorization and download a netCDF file ?
I am referring to this -
http://ncarrda.blogspot.in/2017/07/accessing-rda-opendap-endpoints-with.html
<http://ncarrda.blogspot.in/2017/07/accessing-rda-opendap-endpoints-with.html>
and I get a authorization failed error even though I have
an appropriate .netrc file as well as dodsrc file. Using
standard python and netCDF python I am able to read http
request and response of metadata pages on RDA - it is
only nccopy that is failing. Does anybody have a working
example of nccopy with this redirect-based authorization ?
Best,
Ashwin.
