+=====How-to recipes (a random list)=====
+This is especially intended for CREAM-CE/LSF administrators, to help them finding an equivalent HTC-CE/HTC way to do something.
+=== Close / Open a WN (''badmin [hclose|hopen]'')===
+There are several ways:
+  * From the Central Manager, using ''condor_drain'':
+''[root@htc-2 ~]# condor_drain -graceful -pool htc-2.cr.cnaf.infn.it wn-123.cr.cnaf.infn.it\\
+[root@htc-2 ~]# condor_drain -cancel -pool htc-2.cr.cnaf.infn.it wn-123.cr.cnaf.infn.it''
+  * In the configuration file for the WN, set:
+''\\
+[...]\\
+StartJobs = true\\
+STARTD_ATTRS = StartJobs, $(STARTD_ATTRS)\\
+[...]\\
+''\\
+Then toggle ''StartJobs'' to open/close the WN. Each change requires ''condor_reconfig'' on the machine.
