Using AFS

• To get an AFS token, (assuming you aren't using the PAM module) use klog. You can check the status of your tokens with tokens.
• Your AFS filespace is at /afs/pppl.gov/u/<username>. I usually link this to ~/afs/ on all the machines I work on. With an AFS token, you can write to this space.
• Also once you have your token, you have the ability to run lots of binaries which reside in AFS (like IDL and several Fortran compilers).
  • The easiest (but not necessarily the best) way to do this is to ln -s /a/usr/local /usr/local.
  • An alternative is to link certain directories under /a/usr/local under /usr/local. For instance, to use IDL, you'll need to:

    ln -s /a/usr/local/rsi /usr/local/rsi
    ln -s /a/usr/local/flexlm /usr/local/flexlm
    ln -s /usr/local/rsi/idl/bin/idl /usr/local/bin/idl 
    (other soft links can be made to idlde, idlhelp, etc)
    

    You need flexlm to access the license server (on draco) to run idl (this is done in the background when you try to run idl). You'll need to authenticate to be allowed to access the license server on draco.
