Configuring a CE to support the desktopgrid VO

These are the steps necessary to configure a CE to support the VO named desktopgrid.vo.edges-grid.eu. This is for you if you are a gLite administrator who wants to support this VO to allow jobs bridged from desktop grids via the DG ⇒ EGEE bridge to run on your resources.

Configure the EDGeS YUM repository and install the VOMS certificate:
```
cd /etc/yum.repos.d/
wget http://intraweb.edges-grid.eu/public/grid_deployment/edges.repo
yum install edges-vomscerts
```
Note: This step is optional if you use a recent gLite version with lsc files and you specify VOMS_CA_DN in the VO config.

Add pool accounts and mappings to users.conf and groups.conf:

users.conf:

Add VO configuration to vo.d named desktopgrid.vo.edges-grid.eu:

SW_DIR=$VO_SW_DIR/desktopgrid.vo.edges-grid.eu
DEFAULT_SE=$SE_HOST
STORAGE_DIR=$CLASSIC_STORAGE_DIR/desktopgrid.vo.edges-grid.eu
VOMS_SERVERS="vomss://voms.grid.edges-grid.eu:8443/voms/desktopgrid.vo.edges-grid.eu?/desktopgrid.vo.edges-grid.eu"
VOMSES="'desktopgrid.vo.edges-grid.eu voms.grid.edges-grid.eu 15000 /C=HU/O=NIIF CA/OU=GRID/OU=MTA SZTAKI/CN=voms.grid.edges-grid.eu desktopgrid.vo.edges-grid.eu'"
VOMS_CA_DN="'/C=HU/O=NIIF/OU=Certificate Authorities/CN=NIIF Root CA'"

Note: Everything after an = sign should be on a single long line. No line breaks are allowed between the quotes.

Add or change the following lines in site-info.def as needed:

VOS="desktopgrid.vo.edges-grid.eu"
QUEUES="desktopg"
DESKTOPG_GROUP_ENABLE="desktopgrid.vo.edges-grid.eu"

Run yaim to reconfigure your CE
If you're behind a firewall you should allow 193.224.187.128/25 to access your services.
Finally, send the following information to the VO manager (edges-vomsadm _at_ mail.edges-grid.eu):
- SITE_NAME (as set in your site-info.def, the site name you are publishing in BDII)
- The URL of your site BDII (something like ldap://host:port/mds-vo-name=<SITE_NAME>,o=grid)
- The IP addresses of your CE and all WNs (this can be an address range or a NAT address) where outbound connections from your site may come (this is needed because the EDGeS services are firewalled)

The VO config and example users.conf, groups.conf are also available here.
