10 years ago Hi Christopher,
Apologies for not getting back to you sooner.
I'm a bit busy at the moment due to family things, however I'll try to take a look at this in the next few days.
Any chance you can re-run the install script and paste the output here?
Also, if you could run "sudo ls -l /var/log/x11vnc.log" and paste that here as well it would help!
Thanks,
Matt

10 years ago Hi Matt,
I understand...no rush
I just ran the script from a terminal window logged in as the pi user.
I couldn't access the vncserver at the ip:port below
I can reach the smb server

Please connect to 10.0.1.20:5901 with a VNC client to configure JMRI.
Please note that JMRI will take several minutes to start the first time it is run.
Your config files should be available by browsing to \10.0.1.20\JMRI\

10 years ago ok, thanks, can you run "sudo service vncserver start" and see what that gives you?
From the above, the VNC Server isn't even starting, but I can't see a clear reason why...

What follows is the contents of the x11vnc.log which I could only get after creating an empty file an given access to the "JMRI" user.

* x11vnc was unable to open the X DISPLAY: ":0", it cannot continue. * There may be "Xlib:" error messages above with details about the failure.
Some tips and guidelines:
\ An X server (the one you wish to view) must be running before x11vnc is started: x11vnc does not start the X server. (however, see the -create option if that is what you really want).
\ You must use -display
\ Next, you need to have sufficient permissions (Xauthority) to connect to the X DISPLAY. Here are some Tips:
\ If NO ONE is logged into an X session yet, but there is a greeter login program like "gdm", "kdm", "xdm", or "dtlogin" running, you will need to find and use the raw display manager MIT-MAGIC-COOKIE file. Some examples for various display managers:
gdm: -auth /var/gdm/:0.Xauth
-auth /var/lib/gdm/:0.Xauth
kdm: -auth /var/lib/kdm/A:0-crWk72
-auth /var/run/xauth/A:0-crWk72
xdm: -auth /var/lib/xdm/authdir/authfiles/A:0-XQvaJk
dtlogin: -auth /var/dt/A:0-UgaaXaSometimes the command "ps wwwwaux | grep auth" can reveal the file location.
Starting with x11vnc 0.9.9 you can have it try to guess by using:
-auth guess(see also the x11vnc -findauth option.)
Only root will have read permission for the file, and so x11vnc must be run as root (or copy it). The random characters in the filenames will of course change and the directory the cookie file resides in is system dependent.

10 years ago Hi,
Sorry it's taken so long to get back to you.
Are you running this as the "pi" user or the dedicated "jmri" user?
Please can you run the following and paste the output here:
ps auxf | grep jrmi
Thanks,
Matt

10 years ago Was this ever resolved? I just did a JRM-PI install and have encountered the exact errors as above. Thanks.

10 years ago Hi, I didn't get the output of ps auxf | grep jmri from @topherson and that, coupled with a distinct lack of time recently, has meant that I have not been able to troubleshoot this.
@twknox if you have the same issue, please can you run that command and paste the output here so I can try and debug.
I'm afraid I probably won't get to this for a week or so, but I'd like to see it fixed.

10 years ago Yes, let me reimage so I can start from a new install. I will post it here over the next few days.

I'm new to the pi platform...trying to get JMRI installed in the hopes of having an install to auto boot into jmri & launch withrottle server without mouse keyboard or monitor, but be able to have ssh and vnc access.
Was getting nowhere fast when I found your script. This is amazing as it has installed both java and jmri and lots of other goodies that I don't understand.
However, I'm experiencing an error on startup into the command line...
"error opening logfile: /var/log/x11vnc.log" AND I'm not seeing a message about where (IP:PORT) I connect via vnc like I DID notice on install of your script.
I got around the of the logfile problem by creating the file manually and giving rights to the JMRI user.
Now on restart, I do not receive this error. Still not getting an IP:PORT message. When I look at x11vnc.log I find that the vnc server is not running.
This link from within the logfile http://www.karlrunge.com/x11vnc/faq.html makes me suspect that the vnc server is not starting due to a permissions problem.
To test this theory I launched the gui with startx. then accessed the terminal and started x11vnc and received no errors.
I researched this a bit and trying to get my head around xauth and MIT-MAGIC-COOKIES but I'm getting a bit out of my depth.
Hoping you can shed some light on this. Read on the JMRI user group that you might respond quicker if issues were sent here.
regards, Christopher
