    Lab 4.3.: CSP blocks display of Horizon dashboard

    in LFS263 Class Forum - Discontinued

    Hi,
    this is an issue I am facing in Lab 4.3 (Configuring OpenStack for Onap), Step 4, where the lab users are connecting to OpenStack Horizon dashboard via a SOCKS5 proxy.

    What works:

    • Established SOCKS5 proxy via Openstack-01 and my Firefox browser on my Linux VM
    • Connecting to the OpenStack Horizon URL via the browser (port 5000)

    Where I'm stuck:

    • The output in the browser shows that a Content Security Policy is blocking the display of the Horizon dashboard.

    • Message in the FF developer console:
      "Content Security Policy: The page’s settings blocked the loading of a resource at http: //Horizon-IP:5000/favicon.ico (“default-src”)." // 10.128.0.3:5000 being the Horizon URL as defined in overcloud.rc3

      I understand this is a common problem that can be solved, but I can't find where to manipulate in this specific OpenStack deployment, and since I'm no web developer, I'd appreciate support here.

    -> Please help me fix this situation - thanks!

    Kind regards
    Roberto

      Hi,

      You may need to set the following in your Firefox browser to enable the content to be displayed.
      (Note: These are mentioned in the ONAP Post-deployment steps - Lab 4.5)

      NOTE: Please check your Firefox browser setting to make sure that Remote Proxy DNS setting is on.
      Type about:config in the address bar
      Select "Accept the risk"
      In the Search enter Proxy
      Enable "network.proxy.socks_remote_dns = true" (Just double click to change the flag)
      Please make sure to undo this change after testing, since this could cause potential security risk!

      NOTE: Please check your Firefox settings to allow mixed contents:
      Type about:config in the address bar
      In the Search enter Mixed
      Click on variable security.mixed_content.block_active_content
      Change the value to False (Just double click to change the flag)

      Hi Sriram,

      thanks for your response.
      I set the settings as recommended, however I am still getting the error message.
      Is there another setting I should check?
      Thanks in advance.

      Hi Team,

      could you please provide an update?
      I have left this one aside, but I have now progressed to Lab 8, and there Openstack GUI pops up again.

      As stated above, I have set all the parameters as you have recommended. This still doesn't work.
      Your support is appreciated.

      Thanks, kind regards
      Robert

      Folks,

      this is solved now.

      It is an incredibly easy solution at the end.
      Apart from setting the variables, the URL to visit is not [Openstack-host IP]:5000, but simply [Openstack-host IP].

      There is many ways to do this wrong, apparently. The error was visible from the screenshots - so apparently nobody really knew it is wrong.
      I wonder how many people stumble across this one.

      Regards
      Roberto
