Firstly, you need to become a member of the ILC Virtual Organization (VO).
Follow the workflow at https://grid-voms.desy.de:8443/vo/ilc/vomrs which will require several rounds of confirmations and emails.
Now you can try some of the example commands at http://grid.desy.de/users/ or http://grid.desy.de/ilc/.

The rest of the tutorial assumes that you are running from an lxplus node at CERN and using the bash shell. |
This script will setup the LCG grid tools at CERN.

There is also a script on DESY afs, but it does not appear to work out-of-the-box on lxplus.

VOMS Server for ilc not known! |
when trying to run voms-proxy-init or any other command, then the VOMS information information about the ILC VOMS server is missing and needs to be installed in the home area..
The ilc VOMS file can be found at http://grid.desy.de/etc/vomses/ilc-grid-voms.desy.de and should be placed in the configuration file at added to the list of VOMS configuration data kept in ~/.glite/vomses, or the site's grid administrator can add this information to a central config file.
These commands will download the VOMS file and add the information to the config file.

cd ~ mkdir .glite # only needed if .glite does not exist already cd .glite wget http://grid.desy.de/etc/vomses/ilc-grid-voms.desy.de # fetch the VOMS file touch vomses cat ilc-grid-voms.desy.de >> vomses # assumesadd vomses is an existing fileILC VOMS |
Now the voms-proxy-init command should work correctly.

We will use the European Data Grid (EDG) tools as the UI for testing purposes.
Follow the instructions for submitting a test job at http://grid.desy.de/ilc/ under "Submitting jobs to the Grid".
