[edit] Using GridFTP

It doesn't really make much sense to install these tools one at a time; better to install a whole gLite UI...

However, if you just want to use GridFTP on your own desktop, and it is a fairly standard SL3 setup, you can do the following:

• add SLC3 paths to your YUM / apt config file
• install the GridFTP client following the specific instructions for Grid Canada where appropriate

Now, whenever you want to get a file from, say, castor at CERN, you can do:

• export GLOBUS_LOCATION=/opt/globus
• . /opt/globus/etc/globus-user-env.sh
• grid-proxy-init (or voms-proxy-init -voms atlas:/atlas/ca)
• globus-url-copy gsiftp://castorgrid.cern.ch/castor/cern.ch/grid/atlas/datafiles/testfile file:///home/isabel/testfile (where /castor/cern.ch/grid/atlas/datafiles/testfile is what you would call the file if you were using castor at CERN)

If you get messages like "error: 530 530 no local mapping for GlobusID", it probably means that your ATLAS VO membership is still pending... The grid-proxy remains valid for 12 hours by default, so you don't need to keep re-typing grid-proxy-init for every file, and the first two commands, which create the environment variables, remain valid for the duration of your login session.
