Webcast support for 64-bit Linux systems
WebEx only supports the following Linux operating systems:
- 32-bit Fedora 13/14
- 32-bit Red Hat 5
- 32-bit OpenSuSE 11.2/11.3
- 32-bit Ubuntu 10.x
Viewing a webcast from opensource.com may present a problem if you are on something other than the supported platforms listed above. We found instructions written for Fedora 12 that may be useful. The work-around is to install a 32-bit version of Firefox with Java and Flash.
Configuring a standalone Firefox browser for accessing WebEx on Fedora 12 x86_64
by Travis Gummels
One means of successfully accessing WebEx from Fedora 12 x86_64 is to use a 32-bit version of Mozilla Firefox with Sun JRE and Adobe Flash 32-bit plugins.
- Per the JRE download site, the 64-bit version does not have support for java applets or Java Web Start (JWS is required to run another WebEx like app named Elluminate).
- Per the WebEx System Requirements page only, 32-bit versions of Linux are supported.
Access to the root account so you can install the necessary i686 rpms.
Mozilla Firefox (default available download is 32-bit at time of writing)
Adobe Flash (get the tar.gz for Linux package, default 32-bit at time of writing)
Sun JRE Linux Self Extracting file (not x64)
The following i686 RPM's should be installed:
Note: the downloaded software names are only current as of this writing
pwd = /home/username
$ mkdir firefox32
$ cd firefox32
$ tar -jxf ~/Downloads/firefox-3.6.3.tar.bz2
$ mkdir .mozilla <-- this is for the profile creation later
Java JRE installation
$ chmod +x ~/Downloads/jre-6u20-linux-i586.bin
Scroll to the end of the agreement and accept it.
Do you agree to the above license terms? [yes or no]
$ ln -s jre1.6.0_20 java
Add in the plugins:
$ cd firefox/plugins
$ tar xf ~/Downloads/install_flash_player_10_linux.tar.gz <-- provides libflashplayer.so
$ ln -s ../../java/lib/i386/libnpjp2.so
libflashplayer.so libnpjp2.so libnullplugin.so
Using your favorite text editor, create ~/firefox32/firefox32.sh for starting up the browser:
Take everything between the scissors -- 8< -- below
-- 8< --
firefox -no-remote -P Firefox32
-- 8< --
Then change the permissions:
$ chmod +x ~/firefox32/firefox32.sh
Start firefox using the firefox32.sh script:
Upon first execution of the script the profile manager should come up. Create a new profile named Firefox32 and change the directory to the firefox32 directory + .mozilla i.e. /home/username/firefox32/.mozilla. To change the directory click the Choose Folder button which should be directly below the Enter new profile name text entry box. In the profile manager interface one can leave "Don't ask at startup" checked as the firefox32.sh script above explicitly uses the Firefox32 profile just defined.
Enable Java Web Start - In order for JWS to function the jnlp file type has to be associated with the Java Web Start executable installed with the Java JRE (javaws located in ~/firefox32/java/javaws). The easiest means found for doing this is to find a file of type jnlp and attempt to open it which results in Firefox asking what to do with it. Set the file association so that the javaws executable is used when files of this type are encountered. Possible locations for a jnlp file are:
Visit the following web pages and see if Flash, Java and WebEx function as they should (valid as of time of writing)
- Flash -> http://www.adobe.com/software/flash/about/
- Java -> http://www.java.com/en/download/help/testvm.xml
- WebEx -> http://www.webex.com/lp/jointest/
On Fedora 14, there has been an issue with javaws and selinux. Read more at Bugzilla 572791.
The work-around is to: sudo setsebool -P allow_execstack 1
