The kernel in Fedora includes support for PTP. User space support is provided by the tools in the linuxptp package. To install linuxptp, issue the following command as root:

~]# yum install linuxptp

This will install ptp4l and phc2sys.

Do not run more than one service to set the system clock's time at the same time. If you intend to serve PTP time using NTP, see Section 15.7, “Serving PTP Time with NTP”.
