Detailed Globus Sharing Guide

Authenticate with CRC Endpoint

The first step is to make sure you are authenticated with the ndcrc#dtn01 endpoint. This will allow you to create a shared endpoint of your own. To begin, login to your Globus Online account here, and click on the Transfer Files link.

Click in either text box marked Endpoint and type "ndcrc". You should see a list of all available endpoints with "ndcrc" in the name. The one you need to use is ndcrc#dtn01.

If this is the first time you have connected to the ndcrc#dtn01 endpoint, you will be required to authenticate. Click the Continue button to do so.

You will be redirected to a new site showing you a long list of universities. Type "University of Notre Dame" in the search field, click to highlight University of Notre Dame in the list, then click the "Log On" button. You may also wish to check the "Remember this selection" check-box.

You will be redirected again to the familiar Notre Dame Central Authentication Service (CAS) page. Use your netID to authenticate with CAS and click "Login". You will then be directed back to the Globus transfer files page and a large list of directories will begin to populate. Once you see this, you have successfully authenticated to the ndcrc#dtn01 endpoint. We aren't ready to transfer files just yet, so we can ignore all that for now.

Create a Shared Endpoint

Next you need to create your own shared endpoint hosted by the ndcrc#dtn01 endpoint. To begin, click the Manage Endpoints link at the top of the current page.

You will be presented with a similar list of your current endpoints. Note that you should see the Globus Connect Personal endpoint that you created previously (jolson6#test01 in my example) as well as the newly authenticated ndcrc#dtn01 endpoint. (You may also see other shared endpoints, as in my screenshot. If there aren't any, don't worry. This list will fill up the more you use Globus!)

Now that you have access to the ndcrc#dtn01 endpoint, click the triangle on the right side of the screen to see its drop-down menu.

Click on the tab labelled, "Sharing". Unless you have previously created a shared endpoint, this list should be empty. Click the "+ Add Shared Endpoint" button to proceed.

To proceed, fill out the information in the fields of the box. The source endpoint must be ndcrc#dtn01. The source path MUST be /scratch365/<your_netID>. (You can share only specific directories within your endpoint directory as well, but this can be done at a later point (see below), not here.) Globus only works with files stored in the CRC Endpoint, so do not attempt to use any AFS directory here. In the screenshot, I used my netID "palbert". Make sure you use the correct path. Click the "Create and Manage Access" button when you are finished.

The next step is to share your endpoint with a user. If you know their specific Globus Online username (different from ND's netID), you can select the User radio button and enter their name in the box to search for them.

Type in the name of the person you are searching for in the field, then click the magnifying glass icon to search for them. The search will not auto-populate as you might expect, so don't forget to click the icon. You will then be presented with a list of possible users. Make sure to click the check-box next to the name of the person(s) you would like to share your endpoint with.

You can also send a email invitation for sharing by going to the email radio button.


If you want to share all of your data stored on your CRC endpoint directory with the person, leave the Path field as it is. Note that you can use the path to a specify subdirectory in as well. If you want to do this, simply type /<shared_folder> in this field for the result to be /scratch365/<netID>/<shared_folder>.


When you are finished, click the "Use Selections" button.


Now, click the "Shared By Me" tab. You should now see your shared endpoint.

Share a File

Let's try sharing a file with someone using your new shared endpoint. Click on the Transfer Files link.

Enter in the names of the endpoints you want to share files between. In my case, I used my shared endpoint (jolson6#dev2) as the source and Jimmie's (jimmielyon#dev2) as the destination. After a brief moment, the screen should populate with the available files on both endpoints. Select the file you would like to transfer, then click the arrow corresponding to the direction you want to send the file. In my case, I clicked the right pointing arrow to send jimmie.img to Jimmie's endpoint. This initiates the transfer.

You will be given a notification if your transfer was submitted successfully.

Your file is now being transferred to the requested endpoint. If you want to check on the status of any transfers, click the Activity link at the menu at the top of the page.
