Hi i am new here, 

I recenlty installed opennms on vmware it it polling fine except for dhcp. manua polling is working by issuing the following command

dmin@opennms()> poller:test -i 172.16.0.48 -s DHCP -P example1
Checking service DHCP on IP 172.16.0.48
Package: example1
Monitor: org.opennms.protocols.dhcp.monitor.DhcpMonitor
Parameter ds-name : dhcp
Parameter port : 67
Parameter rrd-base-name : dhcp
Parameter rrd-repository : /opt/opennms/share/rrd/response
Parameter retry : 2
Parameter timeout : 3000
Available ? true (status Up[1])
Response time: 1069.0

but still whenever i scan the ip, it cannot monitor DHCP 

following are my commmands for poller-configuraion.xml

<service name="DHCP" interval="300000" user-defined="false" status="on">
<parameter key="retry" value="2" />
<parameter key="timeout" value="3000" />
<parameter key="port" value="67"/>
<parameter key="rrd-repository" value="/opt/opennms/share/rrd/response" />
<parameter key="rrd-base-name" value="dhcp" />
<parameter key="ds-name" value="dhcp" />
</service>

following are from server-configuration.xml

<service enabled="true">

<name>OpenNMS:Name=Dhcpd</name>
<class-name>org.opennms.netmgt.dhcpd.jmx.Dhcpd</class-name>
<invoke method="start" pass="1" at="start"/>
<invoke method="status" pass="0" at="status"/>
<invoke method="stop" pass="0" at="stop"/>
</service>

<monitor service="DHCP" class-name="org.opennms.protocols.dhcp.monitor.DhcpMonitor"/>

following is from dhcpd-configuration.xml

<DhcpdConfiguration
port="5818"
macAddress="00:06:0D:BE:9C:B2"
myIpAddress="broadcast"
extendedMode="false"
requestIpAddress="127.0.0.1">
</DhcpdConfiguration>
