Re: [Paraview] paraview web issues "authentication error" in browser.

[Ying Xu]

Hi Seb,

Thanks for the info. The client browser opens properly with "--authKey", 
"${secret}" removed.

=>  "sessionURL" :  "ws://192.168.120.8:${port}/proxy?sessionId=${id}"
${port} should be there otherwise  "pvpython pv_web_visualizer.py" is 
not issued.

Thanks!

Ying

Hi Ying,

instead of pipeline, it should be Visualizer, but I've also noticed 
something strange in your launcher config.

Why do you have ${port} here is you are using apache to forward 
the web socket?

Another thing that you can do is remove all the [ "--authKey", 
"${secret}" ] inside the "cmd" sections.

    Hi All

    I tried to install paraview web with apache as the front end and
    followed the information on
    
http://www.paraview.org/ParaView3/Doc/Nightly/www/js-doc/index.html#!/guide/ubuntu_14_04
    
<http://www.paraview.org/ParaView3/Doc/Nightly/www/js-doc/index.html#%21/guide/ubuntu_14_04>

    The web browser can open the index.html and when I tried to open
    localhost:8080/apps/pipeline, the client browser issues a warning
    "authentication error" and pipeline page closed automatically. The
    backend opens a "pvpython pv_web_visualizer.py --port ${PORT}
    --data-dir ${data_dir}", but failed at
    "--authKey ${secret}"

    The OS is Suse 11.2 and I compiled apache 2.4.10 in my home dir.

    httpd-vhost.conf is
