VNC problem from Sunstone interface

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:
oneadmin <at> myto-node:/usr/share/opennebula$ ps aux|grep python
nova      5838  0.0  0.2 118608 23796 ?        S    09:56   0:00 python /usr/bin/nova-novncproxy --flagfile=/etc/nova/nova.conf --web /usr/share/novnc/

oneadmin  6869  0.0  0.0   9516   908 pts/1    S+   10:10   0:00 grep python

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:

Re: VNC problem from Sunstone interface

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?

Re: VNC problem from Sunstone interface

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 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:

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:

Secure WSS wasn't checked, but I tried to check/uncheck and run once again with unchecked - nothing changed :-(

Otherwise, kill your sunstone proxy and restart it manually:

Here seems to be an issue - if websockify process runs in time of sunstone is starting - python process is defunct. If a defunct python proces exist in system, VNC server is disconnected immediately and 10 lines is added to websockify console:

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,

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:

Re: VNC problem from Sunstone interface

Somehow it is trying to connect with wss :S:

10.0.1.125: SSL connection but '/var/lib/one/self.pem' not found

On sunstone, can you check your user properties (users tab -> select user -> update properties).

In the user template, is there a VNC_WSS variable set? To what value? If so, can you delete it? Reload the sunstone page, logout, login and retry?

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

Secure WSS wasn't checked, but I tried to check/uncheck and run once again with unchecked - nothing changed :-(

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

Here seems to be an issue - if websockify process runs in time of sunstone is starting - python process is defunct. If a defunct python proces exist in system, VNC server is disconnected immediately and 10 lines is added to websockify console:

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?

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:

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:

Re: VNC problem from Sunstone interface

YES! This was the issue ...

There was set VNC_WSS="YES" for oneadmin user, I changed it to "NO", restarted sunstone and everything works.

Thanks!

By the way - I'm sure I didn't change this properties anytime - did it changed from ONE version 3.8?

Somehow it is trying to connect with wss :S:

10.0.1.125: SSL connection but '/var/lib/one/self.pem' not found

On sunstone, can you check your user properties (users tab -> select user -> update properties).

In the user template, is there a VNC_WSS variable set? To what value? If so, can you delete it? Reload the sunstone page, logout, login and retry?

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

Secure WSS wasn't checked, but I tried to check/uncheck and run once again with unchecked - nothing changed :-(

Otherwise, kill your sunstone proxy and restart it manually:

Here seems to be an issue - if websockify process runs in time of sunstone is starting - python process is defunct. If a defunct python proces exist in system, VNC server is disconnected immediately and 10 lines is added to websockify console:

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:
oneadmin <at> myto-node:/usr/share/opennebula$ ps aux|grep python
