各位专家,
小弟最近在做ntp时间同步的相关工作。目前遇到一个棘手的问题,无法解决,特来此处请专家会诊!!
现象描述:
采用一台pc server 用vmware虚拟成两台主机,用其中一台机器安装linux系统,用来做ntp服务器。
与其同步的客户机有aix系统,windows 2003 及h3c 交换机等。
目前唯独aix 的两台做双机热备的机器无法同ntp时间服务器同步时间。
ntp时间服务器配置为:其ip地址为:192.168.112.251
restrict 192.168.112.0 mask 255.255.255.0 nomodify notrap
restrict 172.16.0.0 mask 255.255.0.0 nomodify notrap
restrict 192.168.200.0 mask 255.255.255.0 nomodify notrap
restrict 192.168.100.0 mask 255.255.255.0 nomodify notrap
restrict 192.200.10.0 mask 255.255.255.0 nomodify ntrap
restrict 192.200.10.0 mask 255.255.255.0 nomodify ntrap
restrict 192.200.20.0 mask 255.255.255.0 nomodify ntrap
restrict 192.200.100.0 mask 255.255.255.0 nomodify ntrap

server 127.127.1.0 # local clock

aix小机的ntp.conf 配置为:
#broadcastclient
server 192.168.112.251
driftfile /etc/ntp.drift
tracefile /etc/ntp.trace
小机的xntpd 进程开启。但是执行lssrc -ls xntpd
始终显示:
Program name: /usr/sbin/xntpd
Version: 3
Leap indicator: 11 (Leap indicator is insane.)
Sys peer: no peer, system is insane
xnptdc -c peers 显示:
# xntpdc -c peers

=192.168.112.251 192.168.112.7 11 64 1 0.00049 0.037045 15.8750
npt服务器和aix小机都在同一个网段,没有做防火墙限制。
现在insane 始终改变不过来,不知道原因 。。。请教各位啦!!
