今对ubuntu的系统进行snmpd配置,完成后无法启动,经查看syslog日志,有如下报错:

Mar  3 15:11:45 HK-EN-Prod-Web02 snmpd[10060]: error on subcontainer 'ia_addr' insert (-1)
Mar  3 15:11:45 HK-EN-Prod-Web02 snmpd[10060]: /etc/snmp/snmpd.conf: line 146: Warning: Unknown token: defaultMonitors.
Mar  3 15:11:45 HK-EN-Prod-Web02 snmpd[10060]: /etc/snmp/snmpd.conf: line 148: Warning: Unknown token: linkUpDownNotifications.
Mar  3 15:11:45 HK-EN-Prod-Web02 snmpd[10060]: Turning on AgentX master support.
Mar  3 15:11:45 HK-EN-Prod-Web02 snmpd[10060]: Error opening specified endpoint "udp6:[::1]:161"
Mar  3 15:11:45 HK-EN-Prod-Web02 snmpd[10060]: Server Exiting with code 1

 

      今查看发现ipv6未启动,信息如下:

eth0: mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 00:0c:29:a7:5c:96 brd ff:ff:ff:ff:ff:ff
    inet 172.16.1.25/24 brd 172.16.1.255 scope global eth0
       valid_lft forever preferred_lft forever


      解决方法:

1、设置不监控在ipv6上:

#agentAddress udp:161,udp6:[::1]:161
agentAddress udp:161

2、启动ipv6:

net.ipv6.conf.all.disable_ipv6 = 0
net.ipv6.conf.default.disable_ipv6 = 0
net.ipv6.conf.lo.disable_ipv6 = 0
