how to set ntpd listen only 127.0.0.1 ?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



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:*             & nbsp;                 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.
