我在 debian scrap 中使用该ntp软件包，ntpd 进程正在监听数百个未在服务器上配置的 rfc1918 地址。
看一下这个：

有什么想法吗？
答案1
我没有完整的 pre-grep 输出，因为我的滚动缓冲区已满，但是：
# ip addr show dev eth0 |grep 192.168.[12]
inet 192.168.1.1/16 scope global eth0
inet 192.168.1.2/16 scope global secondary eth0
inet 192.168.1.3/16 scope global secondary eth0
inet 192.168.1.4/16 scope global secondary eth0
inet 192.168.1.5/16 scope global secondary eth0
...
这解决了它：
ip addr del 192.168.1.1/16 dev eth0
这很可能是我不久前对 openvpn 配置进行的一些摆弄的副作用。
