system server stopped responding - why?

scoutscout Member
I run the system server (currently 3.11b) on port 5900, but consistently upon trying to connect (locally or remotely) Vine Viewer (3.0) will give me an error that it failed to respond. The availability indicator then stays off.

I am not sure what is going on. I've had a number of problems since I migrated my installation from a G5 Power Mac to a 2009 Nehalem Mac Pro. A few tricks that previously got it back up have not solved this now, including restarting, deleting OSXvnc-server settings from firewall and repopulating, trashing my Vine Viewer preferences.

I have tried 3.1b and was on the previous version before that. The system is running the latest everything from Apple. The firewall is on, OSXvnc-server is listed to allow incoming connections. Screen sharing service is off. I can connect to the old machine remotely on a different port so the router shouldn't be an issue as it is forward to the current LAN IP.

It was just working and then it stopped. The console shows no crash or much else interesting other than:
Mon Jul 27 01:33:00 Athena.local OSXvnc-server[158] <Warning>: 3891612: (connectAndCheck) Untrusted apps are not allowed to connect to or launch Window Server before login.
Mon Jul 27 01:33:00 Athena.local OSXvnc-server[158] <Warning>: Window Server is not available.
Mon Jul 27 01:33:00 Athena.local OSXvnc-server[158] <Warning>: Window Server is not available.
Mon Jul 27 01:33:00 Athena.local OSXvnc-server[158] <Warning>: CGSCreateEventSourceState: cannot resolve shmem.


I don't know when it changed, but previously when I opened the Vine Server app, the client server window would say that the server couldn't start because it may already be running. Now, the client server starts when opened. Using port scan on another machine, 5900 is live only when the client server is started. If I quit the client server and restart the system server, 5900 does not respond.

I am thinking of going back to version 2. Any ideas on what is preventing the system server from operating? What am I missing? Thanks in advance.

    So I think I know what the situation is -- that error indicates that server isn't able to run, either because you are at the login window or another user is logged in at the console (primary display). Running a System Server allows you to connect in this way; and was probably what you had running before.

    To configure the System Server choose Server->System Server from the main menu, set your connection options and hit start. After the System Server is started you can quit the GUI application.

    Thank you, Jonathan.

    I followed your directions and it worked, but I don't understand why and how it didn't work when I tried before. Questions:
    ? Why did the system server stop working?
    ? Why did it not restart when I restarted my computer?
    ? If I connect (from Vine Viewer) and disconnect more than twice, I get subsequent connection failures:
    Connection to Server: _server_ Port:5900 was lost and could not be reestablished.

    Why is this happening and how can I reestablish a connection?

    BTW, before I get this error, the status shows available. I am prompted for password, but then get the connection error.

    I'm not sure if something went awry during the migration or why you had some of the earlier problems.

    For now let's focus on solving whatever remaining issues you have; it sounds like the biggest problem is that after connecting and disconnecting repeatedly you seem to not be able to get in again.

    First, is that JUST disconnecting or are you also logging out or doing anything else that might stop the server?

    The system server stores a log in /Library/Logs/VineServer.log -- you might look at that or post it here as an attachment for clues as to what's happening.

    On this system, I have 1 account, fast user switching is not enabled, I am logging out or putting the machine to sleep. So I am JUST disconnecting the Vine Viewer.

    After trying your protocol, I restarted the machine and I was able to connect to the server before the machine was logged in. I was able to connect again after login, but afterward.

    Here is /Library/Logs/VineServer.log from last login attempt:

    It looks like the server isn't letting go of the disconnected client. I checked the server prefs and it was set to allow only one client at a time. It didn't connect until after I restarted system server.

    Now it appears to be working again. It looks like the Keep existing viewer option was holding on to the connection. But if my Vine Viewer was the original connection and had exclusive access, why wouldn't it be allowed to connect again? Same machine, same LAN address, same Viewer.... Doesn't make sense.
  • Jonathan? Planning to address this further?

    Am I not understanding how this is supposed to operate?
