Selenium Server on Debian with Firefox - NotConnectedException

[Tim Rue]

Hi,

i have a problem and i do not get any further on my own. Hopefully someone of you can help me.

I am trying to set up Selenium Server on a Debian System with Firefox and a PHP Webdriver (https://code.google.com/p/php-webdriver-bindings/). I got the latest selenium server version (2.45.0). For testing i would like to launch firefox in tightvncserver. I already tested my php-webdriver-skript with selenium server and firefox on a Windows 8.1 system. Now i would like to do it on debian server, but the selenium server is not launching firefox. It is aborting with this message after some time: org.openqa.selenium.firefox.NotConnectedException

I've read that this issue often comes with the wrong firefox version according to selenium server version. I already tried out version 24, 31, 32 and 35. But none of them worked for me.

thanks in advance!

Hello

Make sure you export DISPLAY environment variable that matched the port the vnc / xvfb server is running on. Also make sure you run as selenium jar as  the sameuser you launched vncclient...
acid test is to be able to start firefox as the desired user .
If you like please review my vagrant cookbooks on https://github.com/sergueik/selenium_vagrant . It boots a cenos, or ubuntu  box and intalls xvfb / vncviewer . If you like there  is a really big number of similar projects..

Let me know if you have any questions,

Thanks,
Serguei Kouzmine
