Configure the Aspera High-Speed Transfer Server to restrict the use of the root account for transfers. For each privilege that is set to "true", run the following command: $ sudo /opt/aspera/bin/asconfigurator -x "set_user_data;user_name,root;,false" Restart the IBM Aspera Node service to activate the changes. $ sudo systemctl restart asperanoded.service
