Jefferson Lab Lattice Portal - Grid File Manager
Welcome to our instructions on how to use the Grid File Manager web interface ...
The Grid File Manager (GFM) is a java application designed to run on
your desktop.
Using the Grid File Manager, you can manage the files on a data grid host
(like lqcd.jlab.org) without logging into the system.
You can transfer files (even entire directories) from/to your local desktop
to/from the server, or between an unmanaged file system (home directory
or /data) and a managed area within a server,
or between two servers (3rd party transfers)
with just a couple of clicks.
We use Java Web Start to launch GFM from a web page,
automatically downloading the latest version if yours is out of date.
GFM uses https with X.509 certificates to perform privileged operations
securely. Therefore, it needs to read your user certificate and CA
certificate stored on the local system. For 3rd party (queued) file transfers,
it uses proxy certificates automatically generated (once per day), and so
once a day it will also ask for the passphrase to unlock your certificate
store.
Install Grid File Manager:
(Netscape 4.x only)
- Install the Java Web Start software.
- Request your DOE certificate from
DOE Grid Certificate Service.
- Register your DOE certificate at
JLAB HPC web site so that your certificate subject name (DN)
will be used to map your web connection to your local user accout
in the future.
- Run Install java application (need
web start application) to install Jlab HPC CA certificate to your
$HOME/.dg. It is required when generating a proxy certificate to
connect the server securely.
- Export this certificate from
browser into a file (usercert.p12) guarded by a
pass phrase
(this pass phrase is needed when use Grid File Manager interface).
Save this .p12 file to $HOME/.dg directory on all the
desktops where you will access Jlab lqcd web portal service.
$HOME directory is defined by your system property and it may variant
on different operation system or different login. You can find out its
path when you run Install application in previous step.
- After all above steps are completed, clink the link to launch the
Grid File Manager web interface.
- Jlab HPC group signs all JAR files needed by Grid File Manager.
When you using this Grid File manager first time,
Java Web Start will present a
dialog displaying the application's origin, based on the signer's
certificate. Click Start to launch the Grid File Manager application.
Launch Grid File Manager:
- In either Netscape or Internet Explorer click
Grid File Manager link
to launch this interface.
You can also bookmark the link or add it to toolbar for the future use.
- If you are using the Microsoft Windows operating system, Java Web Start
will ask the second time you launch an application if you would like to
create shortcuts or an entry in the Start Menu. If you say "yes," all
future launches of the application can start without a browser.
