Installing NTP on Ubuntu 22.04 LTS


NTP stands for Network Time Protocol. It is a networking protocol designed to synchronize the clocks of computer systems over a network. The primary purpose of NTP is to ensure that all computers in a network have consistent and accurate time information.

Accurate timekeeping is important for various reasons, including:

  • Synchronization: NTP allows multiple devices and systems within a network to have synchronized clocks. This synchronization is crucial for tasks that require coordinated timing, such as distributed computing, file replication, and database transactions.
  • Authentication and Security: Many security protocols and mechanisms rely on accurate time information to establish trust and prevent malicious activities. NTP helps ensure that digital certificates, timestamps, and other security-related processes are accurate and reliable.
  • Log File Accuracy: Accurate timestamps in log files are essential for troubleshooting, forensic analysis, and tracking events in a system or network. NTP helps maintain consistent and reliable timestamps across multiple devices.
  • Global Time Standardization: NTP connects computer systems to various time servers across the globe, which are maintained by highly accurate atomic clocks. This allows systems to adhere to a global time standard, such as Coordinated Universal Time (UTC), and helps ensure time consistency across different time zones and regions.

NTP operates in a hierarchical manner, with multiple time servers organized in a tree-like structure. Each server in the hierarchy synchronizes its clock with a higher-level server, ultimately reaching a primary reference time source that is highly accurate, such as a GPS-based atomic clock or a radio clock. This hierarchical architecture ensures that time information is propagated accurately and efficiently throughout the network.

NTP is widely used in computer networks, including local area networks (LANs) and the Internet, to maintain accurate time synchronization among devices and systems. It is supported on various operating systems and network devices, and its accuracy can be further improved by utilizing multiple redundant time servers and implementing best practices for NTP configuration and security.

In this post, We will show you how to install NTP server on ubuntu 22.04 LTS

Step 1: Run System Updates

Execute the given command in order to update ubuntu’s repository.

sudo apt-get update

Step 2: Installing NTP

Once the package lists are updated, you can proceed to install the NTP package by running the following command:

sudo apt-get install ntp

Step 3: Validate NTP

After the installation is complete, the NTP service will start automatically. However, you can check the status to confirm by running:

sudo systemctl status ntp.service

If the service is active and running, you should see output indicating that it’s running successfully.

Step 4: Configure NTP Server

By default, the NTP service should be configured to use the Ubuntu NTP servers. However, if you need to customize the NTP configuration, you can edit the configuration file using a text editor. For example, to use a different NTP server pool, open the configuration file with root privileges using nano:

sudo nano /etc/ntp.conf

In the configuration file, you can modify the server lines to specify the NTP servers you want to use. Once you’ve made your changes, save the file and exit the text editor.

Step 5: Restart NTP Server

Restart the NTP service to apply any changes you made to the configuration file:

sudo systemctl restart ntp.service

That’s it! NTP should now be installed and running on your Ubuntu 22.04 LTS system, helping to keep your system’s time accurate and synchronized with the NTP servers.

Step 6: Verify Synchronizing

You can verify that your system is synchronizing time with the NTP servers by checking the system’s time and date using the date command:


If everything is configured correctly, the output should display the current date and time synchronized with the NTP servers.


That’s it! NTP should now be installed and running on your Ubuntu 22.04 LTS system, helping to keep your system’s time accurate and synchronized with the NTP servers.
