Java SDK
NTP daemon
APT
Latest glite-yaim
Check your host certificates in /etc/grid-security and its permissions:
-rw-r--r root root 1127 Jun 14 12:27 hostcert.pem
-r root root 887 Jun 14 12:28 hostkey.pem
WMS+LB services requires a wide range of ports
(Set the firewall allowing input for any protocol in the range of ports > 1023 )

Install all packages for a Gilda LCG RB
Apt-get install ig_WMSLB
cp /opt/glite/yaim/examples/siteinfo/gilda_ig-site-info.def /root/RB/my-site-info.def

/opt/glite/yaim/bin/ig_yaim -i -s ./my-site-info.def -m ig_WMSLB
Configure Gilda RB node

6. Testing the WMS
Login to a user interface (sevillaXX in glite-tutor.ct.infn.it):
Create and Edit rb-test.conf with the following line (replace XXX to match your WMS+LB host): [
VirtualOrganisation = "gilda";
NSAddresses = {
“grid-XX.rediris.es:7772” };
LBAddresses = {
{“grid-XX.rediris.es:9000"}
MyProxyServer = "grid001.ct.infn.it"; ]
Try:
Send a job and Monitor the run of your job and if you will be able to retrieve its output, if your are in the right way!

WMS Logs
Logs can be found in
/var/edgwl/networkserver/log/events.log
