           ==== DVS PTP MITM =====

Targets:

h|help		shows this help.txt
b|build		compiles code
c|clean		remove built code
dir		echo directory for manual intervention

The following targets require sudo, ex 'sudo make install'

install		sets up man-in-the-middle
uninstall	remove man-in-the-middle

Installation notes

Creating and using the installation script requires you to work on the terminal and to have the essential command line tools installed.

1. Uncomment the desired options in the beginning of ptp-mitm.c (options below are default):

// #define DISABLE_SLAVE_ONLY 		// Allow DVS to become leader
// #define ENABLE_PTPV2 					// Enable PTPv2 support

2. Open up the terminal by starting the Terminal.app in Applications > Utilities

3. Change to the directory to where you saved the (unzipped) files of this repository. Ex if the files are located on your desktop in a folder dvs-ptp-mitm type cd ~/Desktop/dcs-ptp-mitm.

4. If you don't know wether you have the command line tools installed type xcode-select --install

5. When you thus type make you should see the contents of this readme printed onto the screen.

6. To create/compile the source code to a binary type make build. This should create a file called ptp-mitm in the same folder.

7. To install the binary type sudo make install

8. To uninstall again type sudo make uninstall

To simplify repeated installation (step 6) and uninstallation (step 7) you can also run the two automator apps Activate / Deactivate DVS-PTP-MITM.

Manual Installation

In DVS's application library (on macos /Library/Application Support/Audinate/DanteVirtualSoundcard) rename the original ptp file to ptp-original and copy the compiled ptp-mitm to in place of the old ptp binary.

Application note

As you can also clearly see when looking at the source code ptp-mitm.c what happens is that the new executable calls the original ptp executable with the exact same arguments except for the changed options.

DVS's ptp service comes with more possibilities than actually enabled through normal DVS use.
