 	usage: $CMD {start|stop|status|monitor|meta-data|validate-all}
 
 	$CMD is used to temporarily block ports using iptables.
 
 	It can be used to blackhole a port before bringing
 	up an IP address, and enable it after a service is started.
-	To do that for samba, the following resource line can be used:
-
-	$CMD::tcp::137,138::block		\\
-	    10.10.10.20				\\
-	    nmbd smbd 				\\
-	    $CMD::tcp::137,138::unblock
+	To do that for samba, the following can be used:
+
+	crm configure <<EOF
+	primitive portblock-samba ocf:heartbeat:portblock \\
+	  params protocol=tcp portno=137,138 action=block
+	primitive portunblock-samba ocf:heartbeat:portblock \\
+	  params protocol=tcp portno=137,138 action=unblock
+	primitive samba-vip ocf:heartbeat:IPaddr2 \\
+	  params ip=10.10.10.20
+	group g-samba \\
+	  portblock-samba samba-vip nmbd smbd portunblock-samba
+	EOF
 
 	This will do the following things:
 
 	  - DROP all incoming packets for TCP ports 137 and 138
 	  - Bring up the IP alias 10.10.10.20
 	  - start the nmbd and smbd services
 	  - Re-enable TCP ports 137 and 138
 	        (enable normal firewall rules on those ports)
 
 	This prevents clients from getting TCP RST if they try to reconnect
 	to the service after the alias is enabled but before nmbd and smbd
 	are running.  These packets will cause some clients to give up
 	attempting to reconnect to the server.
 
 	Attempts to connect to UDP and other non-TCP ports which have nothing
 	listening can result in ICMP port unreachable responses, which can
 	have the same undesirable affect on some clients.
 
 	NOTE: iptables is Linux-specific.
 
 	An additional feature in the portblock RA is the tickle ACK function
 	enabled by specifying the tickle_dir parameter. The tickle ACK 
 	triggers the clients to faster reconnect their TCP connections to the 
 	fail-overed server.
 
 	Please note that this feature is often used for the floating IP fail-
 	over scenario where the long-lived TCP connections need to be tickled.
 	It doesn't support the cluster alias IP scenario.
 
 	When using the tickle ACK function, in addition to the normal usage
 	of portblock RA, the parameter tickle_dir must be specified in the 
 	action=unblock instance of the portblock resources.
 	For example, you may stack resources like below:
 		portblock action=block
 		services
 		portblock action=unblock tickle_dir=/tickle/state/dir
 
 	If you want to tickle all the TCP connections which connected to _one_
 	floating IP but different ports, no matter how many portblock resources 
 	you have defined, you should enable tickles for _one_ portblock 
 	resource(action=unblock) only.
 	
 	The tickle_dir is a location which stores the established TCP 
 	connections. It can be a shared directory(which is cluster-visible to 
 	all nodes) or a local directory.
 	If you use the shared directory, you needn't do any other things.
 	If you use the local directory, you must also specify the sync_script
 	paramater. We recommend you to use csync2 as the sync_script.
 	For example, if you use the local directory /tmp/tickle as tickle_dir, 
 	you could setup the csync2 as the csync2 documentation says and 
 	configure your /etc/csync2/csync2.cfg like:
 		group ticklegroup {
 		  host node1;
 		  host node2;
 		  key  /etc/csync2/ticklegroup.key;
 		  include /etc/csync2/csync2.cfg;
 		  include /tmp/tickle;
 		  auto younger;
 		}
 	Then specify the parameter sync_script as "csync2 -xv".

 Resource script for portblock. It is used to temporarily block ports 
 using iptables. In addition, it may allow for faster TCP reconnects
 for clients on failover. Use that if there are long lived TCP
 connections to an HA service. This feature is enabled by setting the
 tickle_dir parameter and only in concert with action set to unblock.
 Note that the tickle ACK function is new as of version 3.0.2 and
 hasn't yet seen widespread use.

 <longdesc>
 If for some reason the long lived server side TCP sessions won't be cleaned up
 by a reconfiguration/flush/stop of whatever services this portblock protects,
 they would linger in the connection table, even after the IP is gone
 and services have been switched over to an other node.
 
 An example would be the default NFS kernel server.
 
 These "known" connections may seriously confuse and delay a later switchback.
 
 Enabling this option will cause this agent to try to get rid of these connections
 by injecting a temporary iptables rule to TCP-reset outgoing packets from the
 blocked ports, and additionally tickle them locally,
 just before it starts to DROP incoming packets on "unblock stop".
