  Synchronizing Networks with NTP
Subject:   What about securing the NTP config???
Date:   2003-01-06 19:49:42
From:   anonymous2
Is there some reson there was no mention of securing the NTP service under *nix?


Actions such as setting the default access level
'restrict default ignore'


Alowing access from loopback:
restrict 127.0.0.1


The Client Network Access levels:
restrict 10.10.10.0 mask 255.255.255.0 notrust nomodify notrap


Then define Timeservers by first defining access levels and then defining the timeserver:


restrict 192.43.244.18 mask 255.255.255.255 nomodify notrap noquery
server 192.43.244.18
restrict 18.145.0.30 mask 255.255.255.255 nomodify notrap noquery
server 18.145.0.30
restrict 192.5.41.40 mask 255.255.255.255 nomodify notrap noquery


Just a few suggestions....
