Hi,
I have read in a book that unless you have very specific needs(and
your own GPS or atomic clock) running ntpd on your machine can be both
a waste of resource and security risk. for that reason some sysadmins
prefer ntpdate(often in a daily
cronjob) to set their system time via NTP
how valid is this claim ?
Pretty invalid. a)How is it a waste of resources( what reseources) to keep
your time accurate? b) ntpdate is disappearing and will no longer be
supported. c) It is true that any program which listens for incoming
traffic is a potential security hole. But I have never seen a claim of
using the ntp port for breakin.
