 * '''lamp:''' Runs the LAMP Portal, the Host Monitoring Collector, the Ganglia MA, and NTP server.
 
-We will likely make the NTP server always enabled in the future, since it's usually (always?) desirable. Our flagship visualization service, Periscope, is not included in the RC1 version of the software, but it will hopefully be included soon.
-
-A couple of things to note. Even if ''node1'' will not be initiating bandwidth tests itself, BWCTL must still be enabled (both endpoints must have BWCTL running for bandwidth tests to work). The same goes for ''node2'' and OWAMP. Enabling the host monitoring collector will automatically run the host monitoring daemon on the node. The data measured by the host monitoring daemons is only stored by the host monitoring collector. The Ganglia MA is actually a SNMP MA that wraps the data store of the host monitoring collector and exports it using the perfSONAR API and schemas.

The same goes for ''node2'' and OWAMP. Enabling the host monitoring collector will automatically run the host monitoring daemon on the node. Because BWCTL and OWAMP require NTP, if any of these two services is enabled NTP will also be started; however, you are only able to configure NTP on nodes that have it explicitly enabled.

 For each node, after selecting the appropriate services we must click the Save button to save the configuration locally.

 === 7. Configuring NTP servers (optional) ===
 
+[[Color(red, This seems to be broken right now. The configuration happens normally, but the nodes are not peering with any of the servers on the list below. We have added "ops" to the template so that it will always be enabled. This should be fine for most hosts.)]]

 This is an optional step. The LAMP image has default configuration for the NTP server. However this might not be the best configuration (i.e. best servers for the nodes to query), or you might prefer to access your preferred NTP servers.
