Network Time Protocol (NTP) synchronizes the date and time with the system clock time. This protocol is useful for managing time during packet switching and latency rate. During packet transmission between server and host, an error “no server suitable for synchronization found” is shown.
This guide will demonstrate the possible reasons and solutions for this error with the following supported content:
- Reason 1: Blocking NTP Packets from Server
- Solution 1: Install ntpdate Package
- Solution 2: Install htpdate Package
Let’s start with the first reason.
Reason 1: Blocking NTP Packets From Server
The prominent reason is that the NTP packets are blocked from the server end. Due to this, these packets do not participate in synchronizing dates and times with the current operating system.
Solution 1: Install ntpdate Package
The best solution to resolve the error is to install the ntpdate package in the operating system. It installs all required dependencies regarding the ntpdate package. The command for installing the ntpdate package is provided below:
$ sudo apt install ntpdate # Debian/Ubuntu $ sudo yum install ntp # CentOS/RHEL $ sudo dnf install ntp # Fedora
After executing the above command, the “ntpdate” with all dependencies has been successfully installed in the system.
Check the Active Status of NTP Services
For checking the active status of NTP services, the “timedatectl” command is utilized with the “status” flag as below:
$ timedatectl status
The output shows that the “NTP service” is installed in the current operating system.
Verify NTP Services
To check the NTP services, the “pool.ntp.org” is a virtual cluster for time servers. For instance, the below script will display the transmission and reception of packets from the host server:
$ ntpdate -d pool.ntp.org
Solution 2: Install htpdate Package
To resolve the error, users can install an alternative package named “htpdate” similar to the “ntpdate”. The package “htpdate” retrieves the date and time from a remote server over the network. The command that installs the “htpdate” package in the current system is mentioned below:
$ sudo yum install snapd
For Arch Linux and Fedora:
$ sudo snap install htpdate-daemon
For Ubuntu and LinuxMint:
$ sudo apt install htpdate
After the execution of the above command, the “htpdate” will be installed in the current system to execute any operation.
Adjust Time Smoothy
It synchronizes the computer time with the web server. To do so, the “a” option is used that adjusts the time smoothly:
$ sudo htpdate -a -l www.linux.org
These are all the reasons and solutions for the error “no server suitable for synchronization found”.
The error “no server suitable for synchronization found” is caused by blocking NTP packets from the server or being unable to synchronize time with system clock time. This error can be resolved by installing the “ntpdate” package following the commands mentioned in this post. Additionally, users can install the “htpdate” package as an alternative to accessing the host services. This guide has explained all possible solutions to encounter the error mentioned above.
