The version of OS X NTP Security Update for Mac you are about to download is 1.0. The software is periodically scanned by our antivirus system. We also encourage you to check the files with your own antivirus before launching the installation. This Mac app is distributed free of charge. Mar 26, 2010 This is the ntp server that shows up in the Date/Time system pref pane GUI. This command doesn't force the Mac to sync with the ntp server at all - it just tell Mac OS X.which ntp. Dec 22, 2014 NTP Critical Security Update for OS X Released by Apple, All Mac Users Should Install Now Dec 22, 2014 - 16 Comments Apple has issued a critical security update to OS X users aimed at patching an exploit with the network time protocol on most Macs. Jan 03, 2013 Automating NTP Setup on Mac OS X. The two primary aspects of time setup are typically setting the time zone and setting the Network Time Protocol (NTP) server. The systemsetup command can be used to set both of these date and time options for Mac OS X computers. To see a listing of the available time zones in Mac OS X use the systemsetup with.
When you’re configuring a Mac to leverage an existing Windows infrastructure, having the clocks in sync is an important task. Luckily, Windows Server has been able to act as an NTP server for a long time. In this article, we’ll look at configuring Server 2008 R2 to be an NTP server for Mac and Linux clients.Note: Before you get started, or any time you’re hacking around in the registry, make sure to do a backup of your registry/SystemState!Mac Os X Versions
To enable NTP on Windows Server, open your favorite registry editor and navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW32TimeTimeProvidersNtpServer. From here, enter a key called Enabled as a dword with a value of 00000001.The NTP Server should look upstream at another NTP host. To configure this, go ahead and navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW32TimeTimeProvidersNtpClient and create Enabled as a dword with a value of 0000001 and SpecialPollInterval with a value of 300:“Enabled”=dword:00000001“SpecialPollInterval”=”300”
NTP would then need a source, so let’s go ahead and create that in the registry as well. To set that up, navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW32TimeParameters and then setup the Type key to contain NTP, the Period key to contain freq and the NtpServer key to obtain the IP address of the server followed by ,0x1, as follows (assuming an IP of 10.0.0.8 for the upstream NTP server:
“NtpServer”=10.0.0.8,0×1”“Type”=”NTP”“Period”=”freq”The w32tm service doesn’t start unless your system is on a domain (and should be restarted if the system is already running as a DC). To starts the service automatically (if needed), use the sc command:
sc triggerinfo w32time start/networkon stop/networkoff
Windows systems can also use an NTP server. To configure the NTP client, navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW32TimeTimeProvidersNtpClient and create Enabled as a dword with a value of 0000001 and SpecialPollInterval with a value of 300:“Enabled”=dword:00000001“SpecialPollInterval”=”300”NTP would then need a source, so let’s go ahead and create that in the registry as well. To set that up, navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW32TimeParameters and then setup the Type key to contain NTP, the Period key to contain freq and the NtpServer key to obtain the IP address of the server followed by ,0x1, as follows (assuming an IP of 10.0.0.8 for the upstream NTP server:
“NtpServer”=10.0.0.8,0×1”“Type”=”NTP”“Period”=”freq”Finally, you can invoke the w32tm service directly to query peers and verify that no skew has occurred with the clocks:
w32tm /query /peers
Viola, you’ve now achieved what could be done using a checkbox on an OS X Server. Hope you’ve enjoyed noodling around in the registry!The two primary aspects of time setup are typically setting the time zone and setting the Network Time Protocol (NTP) server. The systemsetup command can be used to set both of these date and time options for Mac OS X computers. To see a listing of the available time zones in Mac OS X use the systemsetup with the -listtimezones option as follows:systemsetup -listtimezonesOnce you have the time zones you can then use systemsetup with the -settimezone option to configure the time zone on your system. It is often easiest to simply paste the time zone into the command. So to set the time zone to Detroit for example, you would use the following command:
systemsetup -settimezone America/Detroit
Once the time zone has been set then you’ll need to setup the time server. Prior to setting an NTP server, first enable network time. This can be done by using the systemsetup command with the -setusingnetworktime option followed by on or off (according to whether it is being enabled or disabled, in this case enabled):
Finally, set the actual NTP server. To set an NTP server use the -setnetworktimeserver option with systemsetup, followed by the name or IP address of the server. For example, to set the NTP server to ntp.krypted.com you would use the following command:
Finally, you need to verify the time is correct. To do so you can use the date command. Or you can use the systemsetup command with the -gettime option as follows:
If you’re not using an NTP server then you’ll need to use the -settime and -setdate options to set the time and date respectively with systemsetup. Each is separated by a : character. The date is set using mm:dd:yy, so to set the date to July 12th, 2009 use the following command:
To then set the time to 11:30pm with no seconds use the following command:
