Re: [vizstack-users] Configuring VizStack - TurboVNC server failed to start - Problem

[Kumar, S. <shr...@hp...>]

Hi Cristi, 

I feel we are closed to solving this. What's the current permission on ~/.vnc ?

My advice is that you fix the permissions on the ~/.vnc directory. E.g., on my system, ~/.vnc has permissions 

drwx------  2 shree shree      4096 Jan 21 12:34 .vnc

Hi Cristi,

Bad guess! Ok - so now we have to look deeper. Thanks for the additional information.

>>>>>> Hi Shree ! Thank you for the replies.

VizStack runs a daemon on port 50000 by default. The scripts from the other nodes connect to this daemon. Please ensure that your virtual machine is not blocking this connection. If this port is being blocked, then open it and then retry the viz-tvnc script.

>>>>>>> The port is not blocked.

Next, try running /opt/vizstack/sbin/vs-test-gpus. This should return successfully.

>>>>>>> Test PASSED

If all these do not fix the problem, then make a copy of /opt/vizstack/bin/viz-tvnc. Edit the file. Locate the line

 tvncProc = sched.run(cmd, errFile = open("/dev/null","w"))

And edit it to see the error messages

 tvncProc = sched.run(cmd)

Run the edited copy of viz-tvnc. You will see error messages. Pass them on to me to have a look.
