Re: [one-users] VNC problem from Sunstone interface

Tue, 06 Nov 2012 23:18:55 -0800

Any chance the "Use Secure WSS" is checked in sunstone config? Can you check/uncheck and retry with it unchecked just in case?

Otherwise, kill your sunstone proxy and restart it manually:

python /usr/share/opennebula/websockify/websocketproxy.py --target-config=/var/lib/one/sunstone_vnc_tokens 29876


and see if it says something interesting to the console when you are trying to connect to the VM.

Is there any suspicious python process still running after stopping sunstone that might be taking the 33876 port?

(im seeing oneadmin 6942 0.0 0.0 0 0 pts/1 Z 10:10 0:00 [python] <defunct>)

Anything in sunstone.error maybe?

Hi all,

I have a problem to start VNC session from Sunstone interface.

I have Ubuntu 12.04 Server with Opennebula 3.8.1 installed, the newest version of noVNC (no error message), restarted oned, sunstone-server and occi-server too.

After restarting, the python processes are:

When I try to start VNC session from OCCI interface - everything works, VNC session is established.
If I try to start VNC session to the same VM from SUNSTONE interface, a message "Server disconnected (code: 1006)" occurs immediately and python processes are changed:

Paths to files looks to be correct - which could be an issue?
