gtm_add Error in AWS

Thanks S Blakely! In AWS, root is disabled but thanks to your answer I changed the admin user to default to advanced shell (bash) and that allowed the script to run with admin. Both data centers showed up in the BIG-IP DNS VM I ran the gtm_add command in. However, both BIG-IP DNS VM's show the remote data center as blue availability and syncing is not working. Not sure why. Was expecting both data centers to be green and sync to work. Will keep digging. Thanks again.
