How to Setup RClone Using VNC Session with Open OnDemand (OOD)

LCC

  1. Log into the LCC OOD session at https://ood.ccs.uky.edu; you must be on the UK’s network (either VPN or on campus).

  2. Create a new interactive VNC session.

    1. Click the “Interactive Apps” dropdown along the top.

    2. Click “Lipscomb Compute Cluster (LCC)” under Desktops.

  3. Enter details for your job. This should be a quick <1 hour job. As such, it should be run on a debug node.

  4. Click “Launch”.

  5. After the job has been accepted, you will see the following:

    A Lipscomb Compute Cluster interface showing configuration details with 1 node and 4 cores running, featuring compression and image quality sliders, along with launch and view options.

  6. Click “Launch Lipsomb Compute Cluster (LCC)”. A VNC session will be initiated, and you will see a typical Desktop environment:

A desktop environment with a dark blue background displaying two folder icons labeled File System and Home, plus a taskbar at the bottom showing various application icons including CCS Software.

7. Open two terminal windows by clicking the “Terminal Emulator” icon in the taskbar twice:

Two terminal windows open on a Linux desktop showing command prompts for user cascade001, with a dark desktop background and taskbar visible at the bottom.

  1. In one of the terminal windows, run the “rclone config” command:

Running rclone config command to create a new remote
[user@login001 ~]$ rclone config No remotes found - make a new one n) New remote s) Set configuration password q) Quit config n/s/q> n

Follow the prompts, until you get to the “auto config” portion. Press Y for auto config.

  1. A link will be provided for you to load the auto config:

Use auto config? * Say Y if not sure * Say N if you are working on a remote or headless machine y) Yes (default) n) No y/n> y 2025/01/09 11:54:14 NOTICE: If your browser doesn't open automatically go to the following link: http://127.0.0.1:53682/auth?state=6UDNxUDbnELiPd9bgIiZ2A 2025/01/09 11:54:14 NOTICE: Log in and authorize rclone for access 2025/01/09 11:54:14 NOTICE: Waiting for code...

  1. In the second terminal, start Firefox by executing the “firefox” command; this will load the Firefox web browser.

  2. Copy the link from the first terminal and insert it into the new Firefox browser window and press enter. (Right click the link, then hit “Copy Link Address”). You should see the following screen:

  3. Input the Username and Password for the account you wish to link.

  4. Click “Continue” to to allow rclone access.

  5. Continue to follow the commands from rclone.

  6. Once complete, close the VNC session and delete the interactive session from Open OnDemand.
