Kewl toyz!

When we try to use it from a browser in linux at locations like ASU, UAT where they block some traffic, we sometimes get disconnected or worse. However, when we do the same thing from a browser in Windows (e.g. Firefox in both OSes), everything works fine. I found this:

What ports must be open for external users to connect to BigBluebutton?
These ports are 80 (HTTP), 9123 (Desktop Sharing), and 1935 (RTMP). These ports are all TCP ports.

Does BigBlueButon support tunneling?
Yes. If a remote user is unable to connect to port 1935, which typically occurs when a remote user's corporate firewall blocks external access to all other ports except port 80, then their BigBlueButton client will fail to connect to port 1935 and, after about ten seconds, fall back to tunneling through port 80.
on http://code.google.com/p/bigbluebutton/wiki/FAQ#What_ports_must_be_open_for_external_users_to_connect_to_BigBlue

so it would seem the "client" falling back to tunneling through port 80 happens from windows but not from Linux. Maybe I am misreading this, but can anyone enlighten me and/or provide a solution?

There are various issues with BigBlueButton API, flash and connecting via port 80 tunnels that are handled differently from windows, mac and linux.

Each must be investigated via case by case basis (or the devil is in the details).

The best place to research and troubleshoot this might be:

The BigBlueButton community focuses its support in three mailing lists (all hosted by Google Groups). They are:

bigbluebutton-setup -- Setup, instllation, and configuration questions, such as "How do I configure the BigBlueButton client?"
bigbluebutton-users -- End user questions, such as "How do I do X with BigBlueButton?"
bigbluebutton-dev -- All other questions, such as "How do I integration BigBlueButton with application Y?"

The developer mailing list has almost 700 users, so before you post do the following:

Scan the FAQ to see if you questions is answered herein
Search the archives of the associated mailing list -- there's a good chance someone might have already asked your question and the ensuing discussion might help you as well
If you think you've found a bug, check the issues database first.

...end excerpt...

With that said, see:

Issue 785 which refers to flash reconnecting repeatedly under windows: http://code.google.com/p/bigbluebutton/issues/detail?id=785

Release Notes: http://code.google.com/p/bigbluebutton/wiki/ReleaseNotes
What version are you running of the API? Many port 80 tunnel issues were repaired in the later versions. They recommend to update to 10.10 under Ubuntu.

For each issue, you need to report the version of the API, the client OS (Ubuntu?) and Firefox version (on the list or groups at Google)....

Use the source young Jedi nights....
