NTP Cookbook
Installs and configures ntp. On Windows systems it uses the Meinberg port of the standard NTPd client to Windows.
About Testing
In addition to providing interfaces to the ntp time service, this recipe is also designed to provide a simple community cookbook with broad cross-platform support to serve as a testing documentation reference. This cookbook utilizes Foodcritic, Test-Kitchen, Vagrant, Chefspec, bats, Rubocop, and Travis-CI to provide a comprehensive suite of automated test coverage.
More information on the testing strategy used in this cookbook is available in the TESTING.md file, along with information on how to use this type of testing in your own cookbooks.
Requirements
Supported Operating Systems
- Debian-family Linux Distributions
- RedHat-family Linux Distributions
- FreeBSD
- Windows
Cookbooks
- When running on Windows based systems, the node must include the Windows cookbook. This cookbook suggests the Windows cookbook in the metadata so as to not force inclusion of the Windows cookbook on *nix systems. Change 'suggests' to 'depends' if you require Windows platform support.
Attributes
Recommended tunables
-
ntp['servers']
- (applies to NTP Servers and Clients)- Array, should be a list of upstream NTP servers that will be considered authoritative by the local NTP daemon. The local NTP daemon will act as a client, adjusting local time to match time data retrieved from the upstream NTP servers.
The NTP protocol works best with at least 4 servers. The ntp daemon will disregard any server after the 10th listed, but will continue monitoring all listed servers. For more information, see Upstream Server Time Quantity at support.ntp.org.
-
ntp['peers']
- (applies to NTP Servers ONLY)- Array, should be a list of local NTP peers. For more information, see Designing Your NTP Network at support.ntp.org.
-
ntp['restrictions']
- (applies to NTP Servers only)- Array, should be a list of restrict lines to define access to NTP clients on your LAN.
-
ntp['sync_clock']
(applies to NTP Servers and Clients)- Boolean. Defaults to false. Forces the ntp daemon to be halted, an ntp -q command to be issued, and the ntp daemon to be restarted again on every Chef-client run. Will have no effect if drift is over 1000 seconds.
-
ntp['sync_hw_clock']
(applies to NTP Servers and Clients)- Boolean. Defaults to false. On *nix-based systems, forces the 'hwclock --systohc' command to be issued on every Chef-client run. This will sync the hardware clock to the system clock.
- Not available on Windows.
-
ntp["listen_network"]
/ntp["listen"]
- String, optional attribute. Default is for NTP to listen on all addresses.
-
ntp["listen_network"]
should be set to 'primary' to listen on the node's primary IP address as determined by ohai, or set to a CIDR (eg: '192.168.4.0/24') to listen on the last node address on that CIDR. -
ntp["listen"]
can be set to a specific address (eg: '192.168.4.10') instead ofntp["listen_network"]
to force listening on a specific address. - If both
ntp["listen"]
andntp["listen_network"]
are set thenntp["listen"]
will always win.
Platform specific
-
ntp['packages']
- Array, the packages to install
- Default, ntp for everything, ntpdate depending on platform. Not applicable for Windows nodes
-
ntp['service']
- String, the service to act on
- Default, ntp, NTP, or ntpd, depending on platform
-
ntp['varlibdir']
- String, the path to /var/lib files such as the driftfile.
- Default, platform-specific location. Not applicable for Windows nodes
-
ntp['driftfile']
- String, the path to the frequency file.
- Default, platform-specific location.
-
ntp['conffile']
- String, the path to the ntp configuration file.
- Default, platform-specific location.
-
ntp['statsdir']
- String, the directory path for files created by the statistics facility.
- Default, platform-specific location. Not applicable for Windows nodes
-
ntp['conf_owner'] and ntp['conf_group']
- String, the owner and group of the sysconf directory files, such as /etc/ntp.conf.
- Default, platform-specific root:root or root:wheel.
-
ntp['var_owner'] and ntp['var_group']
- String, the owner and group of the /var/lib directory files, such as /var/lib/ntp.
- Default, platform-specific ntp:ntp or root:wheel. Not applicable for Windows nodes
-
ntp['leapfile']
- String, the path to the ntp leapfile.
- Default, /etc/ntp.leapseconds.
-
ntp['package_url']
- String, the URL to the the Meinberg NTPd client installation package.
- Default, Meinberg site download URL
- Windows platform only
-
ntp['vs_runtime_url']
- String, the URL to the the Visual Studio C++ 2008 runtime libraries that are required for the Meinberg NTP client.
- Default, Microsoft site download URL
- Windows platform only
-
ntp['vs_runtime_productname']
- String, the installation name of the Visual Studio C++ Runtimes file.
- Default, "Microsoft Visual C++ 2008 Redistributable - x86 9.0.21022"
- Windows platform only
-
ntp['sync_hw_clock']
- Boolean, determines if the ntpdate command is issued to sync the hardware clock
- Default, false
- Not applicable for Windows nodes
-
ntp['apparmor_enabled']
- Boolean, enables configuration of apparmor if set to true
- Defaults to false and will make no provisions for apparmor. If a platform is apparmor enabled by default, (currently Ubuntu) default will be true.
Usage
default recipe
Set up the ntp attributes in a role. For example in a base.rb role applied to all nodes:
name 'base' description 'Role applied to all systems' default_attributes( 'ntp' => { 'servers' => ['time0.int.example.org', 'time1.int.example.org'] } )
Then in an ntpserver.rb role that is applied to NTP servers (e.g., time.int.example.org):
name 'ntp_server' description 'Role applied to the system that should be an NTP server.' default_attributes( 'ntp' => { 'is_server' => 'true', 'servers' => ['0.pool.ntp.org', '1.pool.ntp.org'], 'peers' => ['time0.int.example.org', 'time1.int.example.org'], 'restrictions' => ['10.0.0.0 mask 255.0.0.0 nomodify notrap'] } )
The timeX.int.example.org used in these roles should be the names or IP addresses of internal NTP servers. Then simply add ntp, or ntp::default
to your run_list to apply the ntp daemon's configuration.
undo recipe
If for some reason you need to stop and remove the ntp daemon, you can apply this recipe by adding ntp::undo
to your run_list. The undo recipe is not supported on Windows at the moment.
windows_client recipe
Windows only. Apply on a Windows host to install the Meinberg NTPd client.
