1、域名解析失败
错误信息:Temporary fAIlure in name resolution (3)
。
原因:无法解析NTP服务器的域名,通常是由于DNS配置问题。
解决方法:检查并修改/etc/resolv.conf
文件中的DNS服务器地址,确保其正确且可用,添加以下内容:
nameserver 114.114.114.114 nameserver 8.8.8.8
2、NTP服务冲突
错误信息:the NTP socket is in use, exiting
。
原因:系统中已有其他NTP服务(如ntpd)正在使用NTP端口(123),导致ntpdate无法运行。
解决方法:停止或杀死正在运行的ntpd服务,可以使用以下命令找到并终止进程:
ps ef | grep ntp lsof i :123 kill 9 <PID>
然后重新运行ntpdate命令。
3、NTP服务器层级过高
错误信息:Server dropped: strata too high
。
原因:目标NTP服务器的层级(strata)太高,超过了允许的范围(0~15)。
解决方法:使用ntpq命令检查目标服务器的层级:
ntpq p weblbserver_128 12:58:26 Dec 28 2014 ::: originate timestamp 0.0.0.0 > 57600.000000 originate timestamp 0.0.0.0 > 57600.000000 originate timestamp 0.0.0.0 > 57600.000000 originate timestamp
