Nan Data Transport System is a Service created to upload automatically each experiment collected to NAN.

Most of times all you have to do is make user all 3 messages are Green, your user is selected and Harvest is Turn on, But some times a couple issues could happen, That's a quick troubleshoot.

1. IF THERE IS A "NAN TRANSPORT IS STOPPED" RED MESSAGE
   • So the Service is stopped, If you don't have sudo permissions ask NMRFAM IT to help you, otherwise just use the command:
     sudo systemctl restart data-transport-daemon.service 
2. IF THE NDTS GUI IS STCUK OR FROZEN
   • If you don't have sudo permissions ask NMRFAM IT to help you, otherwise just use the command:
     • ps aux | grep wish
     • Find the process number: ex. travula+  7280  0.2  0.0 180128  6020 ?        Sl   Oct07  26:07 wish /opt/nan-dtdaemon/nan_gui.tcl
     • Kill The process: ex. sudo kill - 9 7280
     • Open NDTS GUI Again: /opt/nan-dtdaemon/nan_gui
