我已通过docker镜像部署了OpenNMS,并且SNMPv3轮询正常工作,但无法获取SNMPv3陷阱或通知工作。
TRAPD-configuration.xml文件:
<?xml version="1.0"?>
<trapd-configuration snmp-trap-port="162" new-suspect-on-trap="true">
<snmpv3-user
security-name="trapuser"
security-level="3"
auth-passphrase="authsecret"
auth-protocol="SHA"
privacy-passphrase="privsecret"
privacy-protocol="AES"/>
</trapd-configuration>
如果我从另一台主机运行以下主机,OpenNMS通过SNMPv3轮询该主机:
snmptrap -Dusm -v 3 -l authPriv -u trapuser -a SHA -A authsecret -x AES -X privsecret <opennms-host-ip> 42 coldStart.0
OpenNMS不会生成任何事件。在trapd.log中,我可以看到以下警告:
2018-04-26 09:26:33,364 WARN [DefaultUDPTransportMapping_0.0.0.0/162] o.s.MessageDispatcherImpl: statusInfo=1.3.6.1.6.3.15.1.1.3.0 = 0, status=1404
据我所知,这与未知的用户名有关。
同样通知也没有工作,我在trapd.log文件中得到相同的警告,在发送方也有类似的警告。如果我运行tcpdump,我可以看到它从opennms中检索远程engineID。
snmpinform -Dusm -v 3 -l authPriv -u trapuser -a SHA -A authsecret -x AES -X privsecret <opennms-host-ip> 42 coldStart.0

关于我做错的任何想法?
答案 0 :(得分:1)
请你试试以下内容:
打开$OPENNMS_HOME/etc/service-configuration.xml
并在AsteriskGatway
服务后启动Trapd守护程序。为此,请找到以下XML块:
<service enabled="true">
<name>OpenNMS:Name=Trapd</name>
<class-name>org.opennms.netmgt.trapd.jmx.Trapd</class-name>
<invoke method="init" pass="0" at="start"/>
<invoke method="start" pass="1" at="start"/>
<invoke method="status" pass="0" at="status"/>
<invoke method="stop" pass="0" at="stop"/>
</service>
默认情况下,Trapd在Correlator
之后启动。剪切&amp;在AsteriskGateway
服务之后粘贴整个服务定义块:
<service enabled="false">
<name>OpenNMS:Name=AsteriskGateway</name>
<class-name>org.opennms.netmgt.asterisk.agi.jmx.AsteriskGateway</class-name>
<invoke method="init" pass="0" at="start"/>
<invoke method="start" pass="1" at="start"/>
<invoke method="status" pass="0" at="status"/>
<invoke method="stop" pass="0" at="stop"/>
</service>
您现在可以尝试处理SNMPv3陷阱吗?
