Q: How do I use iYFS to access my AFS directory from iOS?


3rd Party Application
iYFS is a third-party program available from the iOS App Store. It is unaffiliated with MIT or IS&T, and IS&T does not recommend, endorse, or support it at this time. However, some members of the MIT community have found it useful to access files in their AFS home directory from their iPhone or iPad. At the time of this writing, the app costs $3.99, and it is up to individual members of the community to determine whether they wish to purchase it or not.

This app has not received formal testing by IS&T and anyone using it does so at their own risk.

  1. When you first launch iYFS, the root of the AFS file system will be displayed. This corresponds to the /afs path on Athena workstations:

  2. You should now select the cell by clicking on the folder labeled "": folder

  3. In most cases, you'll need tokens to authenticate yourself to the AFS servers so you (and only you) can view your files. To do that, click on the Get Tokens button at the top right of the screen. You'll be prompted to enter your username and password:

  4. You should enter your Kerberos username (without the and your password, and leave the "Cell" at the default setting of "".

  5. When you click Done at the top right, you'll obtain your tokens, and return to the cell. Note that the button at the top right now says "Destroy Tokens", and you should do that when you have finished working with your files.

  6. Once you have your tokens, click the "home" icon at the bottom right of the screen, and you will return to the top level of the application. Click on the "signpost" icon at the bottom right of that screen to open a specific path in AFS.

    You can type in the full path of your AFS home directory:

  7. Click Done to view your home directory:
    Home directory

  8. Once you are viewing your home directory, you'll probably want to add it as a "favorite" for quick access. Click the "plus" sign at the bottom left of the screen:
    Add favorite

  9. Click "Add favorite" and give the favorite a name:
    Name of favorite

    The link will now appear on the "home" screen:
