Subject: BBB server inaccessible

Hello,
thank you for helping find out what s wrong with my installation.
I think that applied some bbb updates about 3 days ago and then my bbb
server stopped working with the error below:
(I can access the Demo page on my server, but when I try to log in I have
the error below)

Tarik,

I don't know the cause of your 500 error, but your use of the setip command
is incorrect. You can't put a port on the end of your ip address like that.
Nginx listens on port 80 and forwards requests to
http://xxxx.com/bigbluebutton to the tomcat6 server which is listening on
port 8080 (which is where you're getting that port from).

Chad

Did you setup your development environment? The error is s symptom of
mismatch salt. It might have changed when you updated.

Compare your salt in /var/lib/tomcat6/webapps/demo/bbb_conf_api.jsp and
/var/lib/tomcat6/webapps/bigbluebutton/WEB-INF/classes/bigbluebutton.proper ties.

And if you are running bigbluebutton-web manually, check
grails-app/conf/bigbluebutton.properties

would you need any log file in order to see what happened ??

Hi Tarik,

Can you edit

   /etc/nginx/sites-available/bigbluebutton

and change the value for listen: to 80.  If your having problems editing
the file, google

  "Unable to edit unix file"

There's lots of good tutorials on the internet for understanding basic Unix
concepts.

Thank you Fred,
I changed it back to port 80 and now the comands bbb-conf -check and clean
look much better (all the processes restart with an ok status)
there's only the minor glitch below , but I read that it should be ignored
------------

Before, I had the Demo page at http://serv.domain.com/bigbluebutton
But now I have an Error: "  This page is no longer available, please use
the api. "

*Where should I find that bbb front page??*

Hi Tarik,

The demos have changed to

You have to manually install the demos now (see installation instructions

Thank you Fred,

I followed the instructions of  
http://code.google.com/p/bigbluebutton/wiki/FAQ#How_do_I_setup_new_cl...
=>changed index.html to point to /demo/demo3.jsp + execute permissions
but I still can't have externel users to land on demo3.jsp (???? nor on the
old interface bigbluebutton.html???)
(http://serv.domain.com/bigbluebutton/ leads to "This page is no longer
available, please use the api".
1)how can I direct the external users to the traditional bbb.html page??

I'm using sakai with BBB,

if I connect to the sakai on the bbb server, I can create meetings and also
connect successfully (the meeting link takes me to
http://serv.domain.com/client/BigBlueButton.html  where Java loads on a
page et the users environment is complete )

But if i do it from a remote client, (using the same sakai portal) the
meeting link takes me to http://serv.domain.com/BigBlueButton.html) where
the only thing I see is a blank page with "404 not found ------
nginx/0.7.65 "
On sakai server I changed the bbb parameters to "
http://serv.domain.com/client/bigbluebutton.html " but the bbb server
became unavailable !!!
So I put it back to " http://serv.domain.com/bigbluebutton.html " where I
have the bbb server available.
2) what is missing in my links ??

Hi Tarik,

Are you running Sakai on the same server that's running BigBlueButton?

We recommend you setup a separate, dedicated server for BigBlueButton.  As
well, don't have other applications running on the BigBlueButton server or
allow other applications to use port 80.  For reasons see

http://code.google.com/p/bigbluebutton/wiki/FAQ#We_recommend_running_...

Is it an option for you to run BigBlueButton on its own server?

Hello Fred,
No, the bbb server is a stand alone while sakai is on another server.
I had problems with port forwarding and changed the default BBB port, but I
put it back to 80.

Those two questions below are still puzzling me. Any suggestions??
cheers,

Hi Tarik,

I think you need to slow down a bit -- your making lots of changes to the
configuration, but you really need to slow down and give yourself a chance
to understand how BigBlueButton works. Making random changes does not
improve your setup.

> changed index.html to point to /demo/demo3.jsp + execute permissions

You don't need to give the file execute permissions.

This URL is the entry point for API calls, which is why you are getting
that message "This page is no longer accessible, please use the API"

>  Java loads on a page et the users environment is complete )

The BigBlueButton client is written in Flash, not Java.

> But if i do it from a remote client ...

This sounds like a networking problem.  Can you access the BigBlueButton
demos using a full URL, such as

  http://server_name/demo/demo1.jsp

from both the BigBlueButton server and a separate machine?

> On sakai server I changed the bbb parameters to "

http://serv.domain.com/client/**bigbluebutton.html<http://serv.domain.com/client/bigbluebutton.html>
"
but the bbb server became unavailable !!!

That would be expected as you've changed the API calls for Sakai Meeting
Tool to point to an HTML page, not the API endpoint.

Recommend you

1.  make sure you can access BigBlueButton from another server first (if
not, it's a networking issue).

Is the BigBlueButton server behind a firewall.  If so, please see

http://code.google.com/p/bigbluebutton/wiki/FAQ#Can_I_provide_externa...

2. Set the proper parameters for the Sakai Meeting tool (please read the
Sakai Meeting Tool documentation)

3.  Manually check the URL for your API demos to confirm the work from
other machines.

Tarik: I renamed the old index file and create a new one, so I gave it the
same permissions as the old one.

Tarik: I can access the demo pages from the intranet , but when I connect
from remote I get ""404 Not Found -------- *nginx/0.7.65*"
which means that my connection goes through the router till the BBB server
but just doesn't access the demo pages!!  

Tarik: I'm pretty sure that my network setup is correctly configured now
(did all the steps of the link above and made sure that all  the ports are
open with http://www.yougetsignal.com/tools/open-ports/    )

> 2. Set the proper parameters for the Sakai Meeting tool (please read the
> Sakai Meeting Tool documentation)

Tarik: thre are two parameters:
the bbb.url=http://serv.domain.com/bigbluebutton
bbb.salt=xxxxxxxxxxxxxxxxxxxx
=>think that the config is good since the bbb server is reported in green
on sakai as " available".

> 3.  Manually check the URL for your API demos to confirm the work from
> other machines.

Tarik: the api demo pages work on the intranet, but I get the   ""404 Not
Found -------- *nginx/0.7.65*" from remote (internet)
(If I may, I dont think its a network problem since I get "Welcome to
nginx!' if I enter the name of my bbb server from internet=> Network config
is ok)

Subject: Re: [bigbluebutton-setup] BBB server inaccessible

Hello,
I have a simple setup (3 servers in a intranet behind a router) and I'm
using Port Forwarding.
Internet connexions are fine to my "sakai portal" (on a different port),
but all I get on the BBB server (at port 80) is ""404 Not Found -------- *
nginx/0.7.65*" !!

From my opinion, the last part of this error *nginx/0.7.65*" means that the
connections are hitting the BBB server, but not at the right point (???)

is there something I can modify in order to fix these internet connexions
to my BBB server or should I reinstall the BBB server ??

Subject: Re: [bigbluebutton-setup] BBB server inaccessible

A 404 error could have a bunch of different causes. For instance if you're
trying to access "http://www.yourserver.com/demo" you're going to get a 404
error no matter what.

If you've made lots of changes to the nginx files on your BBB server
though, it might be better to just start from scratch.
