Instructions for using DFS (Distributed File System)

The instructions below will assist LANL users using the DFS file system at LANL and on the ASCI machines. You can access your DFS directories from (most) any ASCI related machine (including ASCI-RED, ASCI-BLUE-PAC, ASCI_BLUE-MTN).

General DFS info available here. Web-based DFS command interface here.

Use the kerberos5 software:

>kinit or k5init  -f your_dce_username@lanl.gov
password: your_dce_password



Acknowledgement and Disclaimer

Then do:

>dcelogin or k5dcelogin
DCE login done.

If you can't find dcelogin or it doesn't work, contact your sysadmin. Each DCE user (at LANL anyway) gets a directory created for him on DFS when the username is created. You may be able to copy the kinit and dcelogin software from from asci kerberos webpage. This webpage requires a login/password and probably only works for Sandia users.

Now do:

clarkkent.acl.lanl.gov> cd /:/users/your_dce_username
clarkkent.acl.lanl.gov> pwd
/:/users/pfay

You can access it from sandia. For example on sasn100.sandia.gov:

ssh sasn100.sandia.gov
...lots of login messages...
sasn100.sandia.gov> k5dcelogin
sasn100.sandia.gov> cd /.../lanl.gov/fs/users/your_dce_username
sasn100.sandia.gov> pwd
/.../lanl.gov/fs/users/pfay

Note that if you need to substitute your dce cell name for lanl.gov. (llnl.gov for livermore, dce.sandia.gov for sandia) If you have any questions, email janus-help@sandia.gov
