Hello Jonathan and thanks for your reply
I had indeed seen that the “VNC” firewall only opened a part of the port range so I created a personal service called “myVNC” to open 5900-5909. I also opened the same range on UDP though I do not know what it means.
After I posted my message I tried to disable ARD to see the effect (combinatory science is a great way to solve problems I don’t understand!) and indeed found that it was not needed. It did not change my situation however. The odd thing though is that even with ARD disabled I cannot use port 5900, VineServer tells me:
VineServer cannot listen on specified port (5900) probably because vineserver is already launched as a startup service
(translated approximately as I’m using a french version, and on top of that VineServer is not in the items to open at startup).
Now this is where it become very odd because I have checked that I can use all the other open ports (5901-5909) provided I only start Vine Server from three specific user accounts on the host (the admin and I think the first two I created…). This is in fact independent of whether the firewall in on or not.
For instance I have tried lauching Vine Server from account nbr 4 while vine server is only running on the administrator account (and not on the number 2 and number 3 account) and I get exactly the same result: the server does not start eventhough the selected port is 5902, which is a port that “works” for accounts number 1, 2, or 3…
I have tried removing all the other accounts (those for which Vine Server does not start on launch, and does not even start when I click on the start server button) and creating a new one, but even this new one cannot start Vine Server.
So I seem to be running into a very strange problem of interaction with something in MacOS. I’m trying to see if I could have done anything fancy while created the number 2 and number 3 accounts, but frankly I can’t think of anything.
