Big Blue Button Installation Issues

Big Blue Button Installation Issues

For some reason I do not see a place to reply to the google code discussion forum for BBB. I would appreciate help from somebody that can help me here.

I installed BigBlueButton. Everything works except for two issues.

1. I do not have audio

I followed the instructions for resolving the issue as provided by the google discussion forum. I have made the changes to bigbluebutton-sip.properties and ran the sudo bbb-conf --clean command. Something is still not right still no audio.

BigBlueButton Server 0.8-beta-3
                    Kernel version: 2.6.18-274.3.1.el5.028stab094.3
                      Distribution: Ubuntu 10.04.3 LTS (32-bit)
                            Memory: 4096 MB

/var/www/bigbluebutton/client/conf/config.xml (bbb-client)
                Port test (tunnel): 66.90.92.6
                              Red5: 66.90.92.6

/etc/nginx/sites-available/bigbluebutton (nginx)
                       server name: 66.90.92.6
                              port: 80
                    bbb-client dir: /var/www/bigbluebutton

/var/lib/tomcat6/webapps/bigbluebutton/WEB-INF/classes/bigbluebutton.properties (bbb-web)
                      bbb-web host: 66.90.92.6

/var/lib/tomcat6/webapps/demo/bbb_api_conf.jsp (API demos)
                  bbb-web-api host: 66.90.92.6

/usr/share/red5/webapps/bigbluebutton/WEB-INF/red5-web.xml (red5)
                  voice conference: FreeSWITCH

/usr/local/bigbluebutton/core/scripts/slides.yml (record and playback)
                     playback host: 66.90.92.6


** Potential problems described below **
# IP does not match:
#                           IP from ifconfig: 127.0.0.2
#   /etc/nginx/sites-available/bigbluebutton: 66.90.92.6
# API URL IPs do not match host:
#                                IP from ifconfig: 127.0.0.2
#  /var/lib/tomcat6/webapps/demo/bbb_api_conf.jsp: 66.90.92.6
#    sip did not start properly

# The IP address (5070) set for sip.server.host in
#    /usr/share/red5/webapps/sip/WEB-INF/bigbluebutton-sip.properties
# does not match the local IP address (127.0.0.2).


# The IP address (66.90.92.6) set for playback_host in
#    /usr/local/bigbluebutton/core/scripts/slides.yml
# does not match the local IP address (127.0.0.2).

Where does the ifconfig come from or shall I say where is the local IP picked up from.

 

2. When using the whiteboard I can delete all drawings and characters made on the board except for the first. That one remains and it then stays on all slides.

Hi Dave,

When you have more than one IP addresses, sometimes BigBlueButton's voice conference server (FreeSWITCH) will bind to one IP address, and BigBlueButton will try to connect to another.  

To configure BigBlueButton to use the right IP address selected by FreeSWITCH, see this FAQ entry.  Please let us know (post a follow-up to this thread) the results after follwoing the resolution steps in this entry.

For the whiteboard marks that sometimes linger (they are only visible to the presenter), it's a open issue that we're working on fixing before shipping BigBlueButton 0.8-final.

Regards,... Fred
