Introduction
Greetings, readers! In this article, we will be discussing Ubuntu 14.04 NTP server and how it can help you keep your system accurate and precise. If you’re an IT professional or someone who uses Ubuntu, then you know how important it is to maintain the accuracy of your system time. It may seem like a simple task, but accurate timekeeping is crucial in various applications, such as log management, billing, and database synchronization.
Before we dive deep into the details of Ubuntu 14.04 NTP server, let’s first discuss what NTP is.
What is NTP?
Network Time Protocol (NTP) is a protocol that allows the synchronization of clocks on a computer network. With NTP, all computers on a network can be synchronized to a single reference clock, making sure that the time is accurate across the network. NTP uses the UTC (Coordinated Universal Time) standard, which is based on the atomic clock, as a reference to synchronize system clocks around the world.
Now that we know what NTP is let’s talk about Ubuntu 14.04 NTP server.
Ubuntu 14.04 NTP Server – What is it?
Ubuntu 14.04 NTP server is a package that provides a network time protocol (NTP) server and client utilities to keep your system time accurate and precise. The NTP server in Ubuntu 14.04 acts as a reference clock for time synchronization within the network. It can synchronize with other NTP servers on the internet or other local servers on the network. Ubuntu 14.04 NTP server can also work as an NTP client, which means it can synchronize time with other NTP servers on the network.
How to Install Ubuntu 14.04 NTP Server?
Installing Ubuntu 14.04 NTP server is easy and straightforward. Follow the steps below:
Step |
Command |
|---|---|
Step 1 |
sudo apt-get update |
Step 2 |
sudo apt-get install ntp -y |
After installing NTP on your Ubuntu system, it’s time to configure it.
How to Configure Ubuntu 14.04 NTP Server?
Configuring Ubuntu 14.04 NTP server is a bit more complicated than the installation process, but don’t worry; we’ll walk you through it step by step. Follow the steps below:
Step 1: Configure the NTP server.
In this step, we’ll configure our Ubuntu 14.04 NTP server. Open the NTP configuration file using your preferred text editor:
sudo nano /etc/ntp.conf
Once the file opens, you will see the NTP server configuration. Edit the file to look like the following:
server 0.ubuntu.pool.ntp.org iburst \server 1.ubuntu.pool.ntp.org iburst \server 2.ubuntu.pool.ntp.org iburst \server 3.ubuntu.pool.ntp.org iburst
Save the file and exit the text editor. This configuration tells the NTP server to use the four Ubuntu NTP servers to synchronize the system time.
Step 2: Allow access to the NTP server.
By default, Ubuntu firewall does not allow NTP traffic. In this step, we will open the NTP port on the firewall to allow traffic.
sudo ufw allow ntp
Step 3: Restart the NTP server.
After making changes to the NTP configuration file and the firewall, you must restart the NTP server to apply the changes.
sudo systemctl restart ntp

Configuring Ubuntu 14.04 NTP server can be a bit challenging for those who are not familiar with NTP. If it’s not configured correctly, it may not work correctly.
2. Needs a Stable Network
Ubuntu 14.04 NTP server depends on a stable network to keep the system time accurate and precise. If the network is unreliable, it may affect the accuracy of the system time.
3. No Graphical Interface
Ubuntu 14.04 NTP server has no graphical interface, and all configurations are done through the command line. This may be challenging for those who prefer graphical interfaces.
FAQs
1. What is the purpose of NTP?
The purpose of NTP is to synchronize system clocks across a network to maintain accurate timekeeping across the network.
2. What is an NTP server?
An NTP server is a server that provides the reference time to synchronize system clocks across a network.
3. Can Ubuntu 14.04 NTP server work as an NTP client?
Yes, Ubuntu 14.04 NTP server can work as an NTP client and synchronize time with other NTP servers on the network.
4. What is UTC?
UTC stands for Coordinated Universal Time. It’s a time standard based on the atomic clock and used worldwide as a reference for time synchronization.
5. How accurate is NTP?
NTP can achieve accuracies of around 1 to 50 milliseconds over the internet and less than 1 millisecond on a local network.
6. How many NTP servers can Ubuntu 14.04 NTP server synchronize with?
Ubuntu 14.04 NTP server can synchronize with up to four NTP servers at the same time.
7. What is iburst?
iburst is an NTP option that forces NTP to immediately step the clock to the correct time instead of gradually adjusting the clock over time.
8. What is the default NTP server for Ubuntu?
The default NTP server for Ubuntu is time.ubuntu.com.
9. How do I check if NTP is running on Ubuntu 14.04?
