Hi everybody,
I have installed BBB 0.7 on Ubuntu 9.04 follows this easy guide
(http://code.google.com/p/bigbluebutton/wiki/InstallationUbuntu).
Unfortunately when open browser http://192.168.1.123 and join to demo
meeting appears a blue screen and this message
Sorry we cannot connetc to the server
Looking the log window this are the last messages
[ERROR] Failed to connect to RTMP://192.168.1.123/video

On Ubuntu iptables allows all traffic

I think that the problem dipends to red5

You need to have three ports open on your the BigBlueButton server. These are ports 80 (HTTP), 9123 (Desktop Sharing), and 1935 (RTMP).

If the BigBlueButton client can't connect to the server, you'll get the error message.

Can you momentarily disable IPTables to make sure it's not a port/firewall problem.  If you are behind a firewall, see

I think that there isn't any firewall rule and with nmap the ports
appears open
Anyway I have made

iptables -F
iptables -F -t nat
iptables -F -t mangle
iptables -P INPUT ACCEPT
iptables -P FORWARD ACCEPT
iptables -P OUTPUT ACCEPT

and the problem remains

Hmmm ... You ran bbb-conf --debug (which looks through the log files for exceptions), can you run

   bbb-conf --check

which checks for configuration problems.

Can you do "bbb-conf --check" and post the output?

And, post /usr/share/red5/log/bigbluebutton.log on www.pastebin.com

Hi Everyone,

Other than the audio delay bbb seems to be running well. I have two questions with regard to the presentation portion of the application. Are there specific fonts that should be used to ensure the conversion process is as seamless as possible? Is there only one transition that is supported? It seems to lose the transitions that the presentation runs with.

Thanks

Hi John,

As far as I know, most fonts work well with the presentation. Some obscure ones may not render properly, or else they'll be converted to another font. Some chinese fonts have also been known to cause issues.

As for transitions, unfortunately they are not kept in the conversion process. Any document you upload to the server is first converted to pdf, then the pdf is converted to Flash. This means that no transitions are kept.

[Robert Wilson]

In limited testing, I've found that converting the presentations to PDFs and then uploading works best.

[Fred Dixon]

Hi Robert,

We recommend always using PDF if possible.  When you use a .ppt or .doc document, for example, BigBlueButton uses OpenOffice 3.2 to do the conversion.  Office 2003 documents convert pretty well, but OpenOffice has troubles with some Office 2007 documents (Microsoft doesn't make it easy to convert).

Have your presenters using PDF and you'll get good results.

Regards,... Fred

P.S.  You can download from Microsoft a free "Save to PDF" module for Office 2007.  See
