Configure your .netrc file¶
Good idea to back up your existing netrc file, if you have one. And while youre at it check for these entries because they might exist in there already:
%cp ~/.netrc ~/bak.netrc
%cat ~/.netrc | grep '.earthdata.nasa.gov' | cut -f-5 -d" "
machine urs.earthdata.nasa.gov login jmcnelis password
machine opendap.earthdata.nasa.gov login jmcnelis password
machine urs.earthdata.nasa.gov login jmcnelis password
machine opendap.earthdata.nasa.gov login jmcnelis password
machine urs.earthdata.nasa.gov login jmcnelis password
machine opendap.earthdata.nasa.gov login jmcnelis password
machine urs.earthdata.nasa.gov login jmcnelis password
machine opendap.earthdata.nasa.gov login jmcnelis password
machine urs.earthdata.nasa.gov login jmcnelis password
machine opendap.earthdata.nasa.gov login jmcnelis password
machine urs.earthdata.nasa.gov login jmcnelis password
machine opendap.earthdata.nasa.gov login jmcnelis password
machine urs.earthdata.nasa.gov login jmcnelis password
machine opendap.earthdata.nasa.gov login jmcnelis password
machine urs.earthdata.nasa.gov login jmcnelis password
machine opendap.earthdata.nasa.gov login jmcnelis password
machine urs.earthdata.nasa.gov login jmcnelis password
machine opendap.earthdata.nasa.gov login jmcnelis password
machine urs.earthdata.nasa.gov login jmcnelis password
machine opendap.earthdata.nasa.gov login jmcnelis password
machine urs.earthdata.nasa.gov login jmcnelis password
machine opendap.earthdata.nasa.gov login jmcnelis password
machine urs.earthdata.nasa.gov login jmcnelis password
machine opendap.earthdata.nasa.gov login jmcnelis password
Add entries to your netrc for these two earthdata.nasa.gov sub domains, at a minimum:
machine urs.earthdata.nasa.gov login jmcnelis password *** machine opendap.earthdata.nasa.gov login jmcnelis password ***
and replace `jmcnelis` and `***` with your Earthdata Login *username* and *password*, respectively...
Replace jmcnelis and *** with your Earthdata username and password, and then run the cell to append these two lines to your netrc file, if one exists. Otherwise write them to a new one. (all set up by -a)
%%file -a ~/.netrc
machine urs.earthdata.nasa.gov login jmcnelis password ***
machine opendap.earthdata.nasa.gov login jmcnelis password ***
Appending to /Users/lowndes/.netrc
Dump the netrc again sans passwords to confirm that it worked:
!cat ~/.netrc | grep '.earthdata.nasa.gov' | cut -f-5 -d" "
machine urs.earthdata.nasa.gov login jmcnelis password
machine opendap.earthdata.nasa.gov login jmcnelis password
machine urs.earthdata.nasa.gov login jmcnelis password
machine opendap.earthdata.nasa.gov login jmcnelis password
machine urs.earthdata.nasa.gov login jmcnelis password
machine opendap.earthdata.nasa.gov login jmcnelis password
machine urs.earthdata.nasa.gov login jmcnelis password
machine opendap.earthdata.nasa.gov login jmcnelis password
machine urs.earthdata.nasa.gov login jmcnelis password
machine opendap.earthdata.nasa.gov login jmcnelis password
machine urs.earthdata.nasa.gov login jmcnelis password
machine opendap.earthdata.nasa.gov login jmcnelis password
machine urs.earthdata.nasa.gov login jmcnelis password
machine opendap.earthdata.nasa.gov login jmcnelis password
machine urs.earthdata.nasa.gov login jmcnelis password
machine opendap.earthdata.nasa.gov login jmcnelis password
machine urs.earthdata.nasa.gov login jmcnelis password
machine opendap.earthdata.nasa.gov login jmcnelis password
machine urs.earthdata.nasa.gov login jmcnelis password
machine opendap.earthdata.nasa.gov login jmcnelis password
machine urs.earthdata.nasa.gov login jmcnelis password
machine opendap.earthdata.nasa.gov login jmcnelis password
machine urs.earthdata.nasa.gov login jmcnelis password
machine opendap.earthdata.nasa.gov login jmcnelis password
machine urs.earthdata.nasa.gov login jmcnelis password
machine opendap.earthdata.nasa.gov login jmcnelis password
Finally, you need to make sure to limit access to the netrc file because it stores your plain text password. Simple on MacOS and Linux:
!chmod 0600 ~/.netrc
