What is the best way to keep the system clock synchronized? I have looked at ntp and netdate. Is one good over the other? Basically I want to know if what is the most secure way to keep the system clock insync. netdate will require me to open up some port 37... is this safe? ntp also requires port 123 (tcp and udp t be open... how safe is that?

Any inputs will be welcome!

The safest way to protect your computer is to disconnect it from the network :slight_smile:

if you want to sync your date, use ntpdate. You don't have to open any well known ports to use an NTP client. The port you are speaking of is for an NTP server..... client processes do not use the same port... they use much higher port numbers.
