Note: The justin get-token method for authentication does not currently work on AL9
The justin get-token command is not distributed on AL9/Spack currently. Please use SL7 if you need to use rucio.
normal tokens (below) for
xrootaccess do work
getting a token for xroot access in AL9
Make certain you have al9 set up
Then use htgettoken to get a token so you can read the files you find.
htgettoken -i dune --vaultserver htvaultprod.fnal.gov #:8200
export BEARER_TOKEN_FILE=/run/user/`id -u`/bt_u`id -u`
The first time you do it it will ask you to authenticate using a web browser.
You should be able to read files at remote sites now.
You may need to repeat the htgettoken as the interactive tokens are pretty short-lived. Batch jobs do their own tokens.
