Troubleshooting AFS

Objective

Find out if AFS is working correctly in the U-M environment, or troubleshoot a problem with AFS.

Environment

As written, this applies to Linux and Mac computers. It may also apply to Windows, but that environment was not tested by the authors.

Procedure

  1. Open a terminal window.
  2. You can run the commands klist to find out if you have a Kerberos ticket and/or tokens to check for an AFS token.
  3. Use the command kinit uniqname@UMICH.EDU to get a Kerberos ticket.
  4. Run aklog to obtain an AFS token (or click "Get new Token" in the graphical window, say when using the Auristor client on a Mac).
  5. Optionally, check for a token with the tokens command.
  6. Try to access /afs/umich.edu.

For testing purposes, it is useful to know the kdestroy and unlog commands, which remove your Kerberos tickets and AFS tokens, respectively.
