Hi Trevor,
there is no need to guess the names of the CEs.
The command:
ldapsearch -LLL -x -H ldap://lxshare0222.cern.ch:2170 -b
"mds-vo-name=local,o=grid" "(objectClass=glueCE)" dn
queries the BDII at CERN (you can replace this by your local BDII).
This returns a list of the CEs in LCG1.
This list is sometimes not complete, but gives you the correct names
for the CEs that are
there.
