Logging into AFS (aka Obtaining AFS tokens)

Without authenticating, you may be able to read AFS directory listings, but will not be able to read or write where you expect to. To access files, either:

  1. Use the AFS menu:
    1. Click the AuriStor icon on your menu bar
    2. If “Startup AFS” is visible, click it, then click the AuriStor icon again (Login with your CSAIL Kerberos username in lowercase and @CSAIL.MIT.EDU all in uppercase).
    3. Click “Get New Token”. If prompted, enter your CSAIL kerberos username and password. – or:
  2. From the command line (eg,
    1. kinit
    2. aklog

Credentials obtained using either approach will expire after 12 hours. (If you’ve turned it on, the AuriStor Menu icon will show a red X when this happens.) Repeat the above instructions (A or B) to regain access.
