Hello, all.

 

I would like to use ntpd for time sync not rdate or ntpdate.

 

but after installation the ntpd, I found that listened at all interfaces like below.

 

udp        0      0 192.168.111.2:123           0.0.0.0:*                               11528/ntpd
udp        0      0 xxx.xxx.62.20:123           0.0.0.0:*                               11528/ntpd
udp        0      0 127.0.0.1:123               0.0.0.0:*                               11528/ntpd
udp        0      0 0.0.0.0:123                 0.0.0.0:*                               11528/ntpd


 

Is there any way or option that only listen 127.0.0.1 for security reason?

 

 

Thanks in advacne.
