If you remove the NTP drift file altogether, it will take longer for ntpd to figure out the drift rate and therefore write the drift file. I only serve time to my LAN, not the outside world (mainly because nobody can get to my servers due to restrictions imposed by HughesNet). Is there some issue with the NTP server itself ? I do not think it should be empty as it should store error in frequency of the system clock.

We recommended /etc/ntpbecause the file is small and won't have to compete for space in /var wherethe log files get located.You don't need to create an empty drift file.

Maybe, I should have let the daemon create the file. Im confused. Once you get it going, that value will be updated periodically by the daemon so you only do this one time. If you need to reset your password, click here.

You can poke a floating point number into that file to give the NTP daemon a place to start (NTP will update that value over time); as root, try Code: echo Im confused. Notices Welcome to, a friendly and active Linux Community. Please Help .!!

I killed them all. Should you need to recompile ntpd in order to use them, I think the ./configure flags will include "--enable-WWV --enable-CHU --enable-AUDIO-CHU". flags in your ntpq output makes me think that the issue is something else, though.
