I am stuck in a messy situation where I should install an environment with the "ptpd" time-service. Now my problem is that my ptpd-server is running on Ubuntu 16.04 which serves the newest ptpd-version 3.2.1 by default. But all my clients are running on Ubuntu 14.04 which serves ptpd-version 2.2.2 by default. Is there a way I can get version 3.2.1 running on Ubuntu 14.04 or -if not- is there a way I can get version 2.2.2 running on Ubuntu 16.04? I just have to install the same ptpd-version on both systems. I do have some experience in Linux but I am not an expert on this so it would be very nice if someone could give me a step-by-step tutorial how to do this. Thank you in advance!

I finally figured out how to install ptpd 2.3.1 on Ubuntu 14.04 with autostart after system reboot, here's my step-by-step tutorial:

  1. Download ptpd2.3.1 from Sourceforge

  2. Copy ptpd-2.3.1.tar.gz to /opt:
    sudo cp ptpd-2.3.1.tar.gz /opt

  3. Navigate to /opt
    cd /opt

  4. Untar the file:
    sudo tar xvzf ptpd-2.3.1.tar.gz

  5. Delete the file ptpd-2.3.1.tar.gz:
    sudo rm -rf ptpd-2.3.1.tar.gz

  6. Rename the folder ptpd-2.3.1 to ptpd:
    sudo mv /opt/ptpd-2.3.1 /opt/ptpd

  7. Navigate to /opt/ptpd:
    cd /opt/ptpd

  8. Run the following three commands:
    (If you are configuring the ptpd-master, insert:)
    sudo ./configure
    (If you are configuring the ptpd-slave, insert:)
    sudo ./configure --enable-slave-only

    sudo make
    sudo make install

  9. Create a file ptpdStart.sh inside the folder /usr/local/bin/:
    sudo touch /usr/local/bin/ptpdStart.sh

  10. Edit that file:
    sudo nano /usr/local/bin/ptpdStart.sh

  11. Paste the following two lines, then save the file and exit the editor (of course you have to replace < networkinterface > with the real name of your networkinterface you want to use for ptpd-traffic.):
    sleep 30
    (sleep is important(!) as ptpd will NOT START if it does not find any functional network-connection on startup)
    If you are configuring the ptpd-master insert:
    sudo /opt/ptpd/src/ptpd2 -M -i <networkinterface>
    If you are configuring the ptpd-slave insert:
    sudo /opt/ptpd/src/ptpd2 -s -i <networkinterface>

  12. Make the file executable:
    sudo chmod +x /usr/local/bin/ptpdStart.sh

  13. Edit the file /etc/rc.local:
    sudo nano /etc/rc.local

  14. Before exit 0 paste the following line then save the file and exit the editor (do NOT delete the exit 0):
    /usr/local/bin/ptpdStart.sh

  15. Reboot your computer and check if ptpd is running:
    ps -A | grep ptpd2
    Note: If nothing is shown, then ptpd is not running! In this case check the steps again carefully!

Note! Optional: If you have some more processes you want to autostart via rc-.local-file you have to separate those commands by inserting an «&». Example:
/usr/local/bin/ptpdStart.sh &
/usr/local/bin/myOtherStartScript.sh
exit 0

For additional options please check the online-documentation of ptpd.

since ptpd depends on libc6 (>= 2.15) and nothing much else you could try to download the ptpd package from that page and install it on the 16.04 system with dpkg -i (or the other way around - install the newer ptpd on the old systems).

Or update your 14.04 systems to 16.04?
