How To Install linuxptp on CentOS 8
linuxptp is PTP implementation for Linux
Introduction
In this tutorial we learn how to install linuxptp on CentOS 8.
What is linuxptp
This software is an implementation of the Precision Time Protocol (PTP) according to IEEE standard 1588 for Linux. The dual design goals are to provide a robust implementation of the standard and to use the most relevant and modern Application Programming Interfaces (API) offered by the Linux kernel. Supporting legacy APIs and other platforms is not a goal.
We can use yum or dnf to install linuxptp on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install linuxptp.
