Setting up VNCauthproxy

[Anuj AJ]

Greetings chaps. 

I have the ganeti web up and running on 0.10.2 version, and right now trying to include the VNC capability for console. 

So i ended up cloning the git repo to my /usr/local dir. 

Here is what my problem is - 

root@exec01:/usr/local/twisted_vncauthproxy# ls

COPYING  LICENSE  MANIFEST.in  README.mkd  setup.py  twisted  vncap

root@exec01:/usr/local/twisted_vncauthproxy# twistd --pidfile=/tmp/proxy.pid -n vncap

Traceback (most recent call last):

  File "/usr/bin/twistd", line 14, in <module>

    run()

  File "/usr/lib/python2.7/dist-packages/twisted/scripts/twistd.py", line 27, in run

    app.run(runApp, ServerOptions)

  File "/usr/lib/python2.7/dist-packages/twisted/application/app.py", line 652, in run

    runApp(config)

  File "/usr/lib/python2.7/dist-packages/twisted/scripts/twistd.py", line 23, in runApp

    _SomeApplicationRunner(config).run()

  File "/usr/lib/python2.7/dist-packages/twisted/application/app.py", line 386, in run

    self.application = self.createOrGetApplication()

  File "/usr/lib/python2.7/dist-packages/twisted/application/app.py", line 446, in createOrGetApplication

    ser = plg.makeService(self.config.subOptions)

  File "/usr/local/twisted_vncauthproxy/twisted/plugins/vncap_proxy.py", line 27, in makeService

    from vncap.control import ControlFactory

  File "/usr/local/twisted_vncauthproxy/vncap/control.py", line 10, in <module>

    from txws import WebSocketFactory

ImportError: No module named txws

since this is production environment, i did export the PYTHONPATH variable to "." from the folder. 

root@exec01:/usr/local/twisted_vncauthproxy# printenv | grep PYTHON

PYTHONPATH=.

root@exec01:/usr/local/twisted_vncauthproxy#

I do believe i could export the variable to be PYTHONPATH=/usr/local/twisted_vncauthproxy/

Meanwhile, i havent been able to run the VNCauthproxy app yet. 

On the side note, i have also replaced localhost to my server FQDN in the settings.py under ganeti web manager. 

Hope someone can help me with this

Here is more info on the clone -

You need to use the virtualenv. In the root of the project, run
`source venv/bin/activate` and you'll notice your prompt change. Then
it shouldnt matter what directory your in, and the dependencies will
be available, so you can run twistd -n vncap and you'll be able to get
VNCAuthProxy running.

Ahhh .. it works now .. problem was it wasnt clear where the python venv needed to be sourced. 

I should have realized that there was not venv folder under the clone of the VNCProxyauth app.

Both servers came up .. the vncap and flashpolicy .. 

Although i still have issue 

Each time i try to access console of a virtual machine from the web manager. It only responds back with >>>>>> "Must set host and port"

I see these ports are open 

tcp        0      0 *:843                   *:*                     LISTEN

and

tcp        0      0 localhost:8888          *:*                     LISTEN

I can telnet to port 843 from my laptop to the server. 

other ports are allowed as well at the moment. 

Any suggestion what that message is all about ??

Thanks

Can you connect with a standalone vnc client? (not using the Web interface)

[Chance Zibolski]

You say that you don't see any ports in these ranges open. Could you
please provide a pastebin of the command + output your running to
determine this? Also, when you run the VNCAuthProxy, could you paste
the output of the command your using plus the output of it for that as
well?
