IO error uploading presentation under Ubuntu UI #734

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
When installing the 7.1 server on Ubuntu 10.10 64bit, everything works as 
expected.
When trying to upload a presentation, however, uploading from another Ubuntu 
(tried 10.04 32bit) with either Firefox 3, 4 or Chromium 7, I invariably get an 
"IO Error: Please contact administrator.null" message.

Uploading from Windows works fine, which makes me think it is a Flash problem.

I've also tried with the debug version of the Flash plugin 10, didn't work 
either.

As general "feeling" remark, it seems as though the Firefox version was not 
uploading at all: the upload progress bar jumps from 0 to 100% in an instant 
while under Windows it takes around 15 seconds to complete, for the same 
presentation.

Hope it helps...

I think we've seen this before ... need to try and reproduce it, but you may be 
correct in that it's a Flash problem.

I'm getting the same problem but not for every file  occasionally it works but 
most of the time it doesn't.  I have Safari and Firefox, Ubuntu 10 64 bit and 
Flash 10 (note that I reported some as yet unresolved camera issues with Flash 
10 (latest vs and Safari and Firefox).

It an issue that occurs when the server doesn't have connectivity to the folder 
/var/bigbluebotton. The only thing you need to do is chown -R tomcat6:tomcat6 
/var/bigbluebotton in the server of bigbluebotton. Cheers

No, it's not related to permissions. It is an Ubuntu *client* problem. When 
uploading on the exact same server configuration but from Windows, it works 
like a charm.

Hi Guys,

Can you try the suggestion at

  http://code.google.com/p/bigbluebutton/wiki/FAQ#I_can't_upload_a_presentation_from_Linux

and let us know if you get the upload presentation to work.

First attempt (with slow connection) show no improvement. Uploading everything 
slowly (that part is ok) but then failing at the moment of converting the 
presentation (same IO error).
Will try again tomorrow with faster line (just in case... I don't know, maybe 
the slowliness is causing some kind of TCP header not to be sent...?)

Ah yes. Since so many people experience this problem and a basic function does 
not work any more, I would suggest to put it on Priority high

First we need a reliable way to reproduce the issue. It does not seem to happen 
on every ubuntu installation. We'll keep an eye open for it.

New Information: I uploaded it with a windows client and ... it works !?!
And Yes, I read

om_Linux

So there mus be another bug :(

Crap! Using the same client and the demo.bigbluebutton server, the bug is not 
reproducable :( So it must be something with an Ubuntu Client and an Ubuntu 
server

Original comment by derarn...@web.de on 14 Jan 2011 at 11:46

OK. Its about the size of the presentation. I exported it with 75DPI and voila, 
it works with ubuntu - ubuntu .... Perhaps that helps. Also the IO Error is 
received before the conversion step.

this solution worked for me:
( as I do not use VOIP, not reinstalled the feature )

[portugues do Brasil]

 - Remova tudo o quer for openjdk, e instale o Java da Sun
 - reinicie o computador
 - reinstale o bigbluebutton, (e não reinstalei a parte de voip, até agora, tudo bem)
 - refaça o link simbólico para o bigbluebutton no nginx
 - reinicie o serviço nginx

[Google translate portuguese to english] ( my english is bad :( )

  - Remove everything you want is openjdk and install Java from Sun
  - restart the computer
  - reinstall bigbluebutton (and not reinstalled the part of voip, so far, so good)
  - redo the symlink to bigbluebutton in nginx
  - restart the nginx

# apt-get purge openjdk*
# apt-get install sun-java6-jdk

# reboot

# apt-get install bigbluebutton
# cd /etc/nginx/sites-enable
# ln -s ../sites-availabble/bigbluebutton
# /etc/init.d/nginx restart
# bbb-conf --clean

Here is the problem.

Red5 has a dependency on openjdk !

GoogleCodeExporter commented 9 years ago 
It should depend on "sun-java6-jdk" as per the installation instructions here:
* http://wiki.red5.org/wiki/Install

The maintainer of the debian package must update the control file accordingly.

We've been using openJDK from the beginning of the BigBlueButton project.  

We'll need to test if changing to sunJDK has any effect.

I have found that this problem appears when server or/and client does not have 
connection to the Internet. When I click upload button server sends some packet 
to the outer address of my router. So if my server does not see outer net it 
produces this IO Error.

I tried to change openJDK to sun-java6-jdk. Behavior of the server did not

Ezeq.mina,

Can you paste the contents of 

  sudo bbb-conf --check

to this thread.  We need to start narrowing down the circumstances under which 
this bug occurs.

I think this problem might be related to the user using HTTP Proxy in their 
browser, but the POST request by the Flash client to upload the slides does not 
use the local HTTP Proxy settings.

Hi Fred

I have not been through them all because it seems that the results are
mixed and inconclusive. As this post originated a long time ago I was
wondering if you had a definitive fix for 0.81? If not I'll have a play
around. I normally try to avoid this with Linux as it usually causes
something else to break in the process.

Thanks

Rob

Hi Rob,

Definitely check out the link to the discussion group (it talks about the HTTP 
Proxy settings).

The definitive answer is the uploads should work *if* there is no HTTP proxy in 
place.  For more information, check the link.

Hi Fred

We are not using a proxy, we are testing locally on lan at the moment, I am
connecting through demo server.
I am going through the logs at the moment. If you can think of anything
that I should take particular interest in then let me know.

Thanks

Can you try uploading a document to your server from a Windows client and let

Hi

No it does not work. I am using Windows on my PC to do this using i.e 10.
Same results with Chrome.

Is is Java or Flash facilitating this upload? I read the discussion on Sun
jdk as opposed to Open jdk but cannot see why this would cause a problem.

Hi Fred

Not to worry I got it working. The problem was caused during the
installation process. When you do the dist-upgrade at the beginning of the
install it seems to install something which messes with BBB system.
Probably an upgraded version of jdk or something, anyway I skipped this
step this time round and all works fine now, after 4 attempts I might add!!

Hi Fred

Can you tell me why the recommendation for bandwidth is so high(below), on
investigation I can see nothing like this being used during multiple
connections to our server from the web. However I am seeing a 5 second lag
on video, but this is not bandwidth related.

Thanks

Rob
Bandwidth RequirementsWhat are the bandwidth requirements for running a
BigBlueButton server?

You'll need good upstream and downstream bandwidth from the server. We
recommend (at least) 100 MBits/second bandwidth in both directions.
