the NTP socket is in use
I'm trying to get my Mac OS X to automatically sync time with NTP. However, I keep getting an error message. Here is the command and the output:
$ sudo ntpdate pool.ntp.org
Anyone has an idea what is happening here? I use the same command on my Ubuntu computers and it works fine.
OS X has built-in NTP synchronization, I guess it is conflicting with your command.
Go to System Preferences > Date and Time and there you can set up NTP.
Why do you have to set it up this way? I thought if you have configured it in System Preferences, it should automatically sync up with whatever NTP server that you have specified?
I guess you can try the ntptimeset command.
The ntptimeset command reads your ntp.conf file to determine which NTP server to sync up with.
I believe this is how you run it:
-s sets the system clock
Thanks. Didn't realize "Set date & time automatically" in System Preferences is the same as NTP. I guess that answers why NTP client couldn't bind the socket.
I guess I've been using the UNIX shell too long . . . I still use "Terminal" 90% of the time on Mac OS X.
I couldn't find ntptimeset. I am using Mac OS X 10.5.4. Is that an utility on newer or order version of Mac OS X?
I have 10.5.6. Apple must have removed it in Leopard.
u'r using ntp so u can't run ntpdate, kill ntpd and retry ^^
OS X uses ntpd instead of ntpdate. You can learn how OS X sets/adjusts time by looking at these Apple Developer pages:
In short, you can specify multiple NTP time-servers in your /etc/ntp.conf like this:
On my Mac, the /var/lib/ntp/ntp.drift file didn't exist, so I created the "ntp" folder and then the file
A reading of the above-listed Apple dev pages will give a bit of insight into my settings.
