Can't access

by landgate_satsys » Mon Mar 22, 2021 4:33 am America/New_York

I've been accessing ancillary data from the routinely. Since Thursday 18/3 I've been unable to access ancillary data. I am also unable to download level0 MODIS Aqua and Terra PDS files using a subscription.

As an example I used the following command to access ancillary data:

/usr/bin/wget --load-cookies ~/.urs_cookies --save-cookies ~/.urs_cookies --auth-no-challenge=on --content-disposition ... 0.0400.003 -v -d

URI encoding = âUTF-8â
Converted file name 'PM1ATTNR.P2021070.0400.003' (UTF-8) -> 'PM1ATTNR.P2021070.0400.003' (UTF-8)
--2021-03-22 08:27:43-- ... 0.0400.003

Hi Jackie,

Did you follow the steps to create a .netrc file before running your command?

When I tried your command before creating the .netrc file, I get a similar error to the one you described. Once I set up my .netrc file correctly, then ran the command, the ancillary data downloaded.

Here is the link with instructions: ... wnload_sec

Thank you for your reply Alicia. I followed the steps to create a .netrc file and have been downloading data for several months using this method. Our colleagues at another organisation are experiencing the same issue with the SSL handshake.
