Re: No possibility to access camera and microphone

[Marcus Schulz]

Hi,
I just subscribed  to this list. I had the same problems and managed to get it 
works after tweo nights. I needed it also for a virtual classroom (who does not 
at the moemnt?? ) and for office.Please don't blame me, if i did not follow 
some rules here at the moment.I just want to help.
My set up: ubuntu 18.04 lts image at a Strato VServer. OpenMeeting M3.
First steps:I took the installation guide for ubuntu I found at the open 
meetings project site. Worked like a charm.Then I saw green bars when someone 
spoke, but no sound and no video except my own.
first i had to run kurento not as user nobody as decribed, but I used default 
kurento. Otherwise there where exceptions cause home folder is "/nonexistent" 
and gstreamer caches failed to work.Not sure if it's important, but I fixed it 
for me. My openmeeting installation runs with user kurento also. Just change it 
in the /etc/init.d/tomcat3 skript and chown -R kurento /opt/open503 of 
course.When the compilation of ffmpeg that is made by the skript provided 
fails, just install the missing dev packages. Don't remeber all. But's that's 
easy to find out, because "make " complains about.
Then I saw in the logs that connection to kurento server fails for web sockets.
I read in the net and found that a turnserver is needed, when clients accessing 
kurento are located behind NAT. Guess almsot every home dial has such a setup, 
so I did it.If I am wrong with it, and that's only needed, If openmeetings is 
behind NAT, please tell me. Than I remove it again.
if needed:
apt-get install coturn
vi /etc/turnserver.conf
configure 
this:realm=kurento.orguser=kurento:somepasslog-file=/var/log/turnserver/turnserver.log
I think that has been all.


Then:
vi 
/etc/kurento/modules/kurento/WebRtcEndpoint.conf.iniedit:turnURL=kurento:somepass@:3478
restart everything.
Than didn't work very much better also, so I took a look at iptables log file.
I added this rules:
iptables -A INPUT -p udp -m udp  --dport 1:65535 -j ACCEPTiptables -A 
OUTPUT -p udp -m udp  --sport 1:65535 -j ACCEPTiptables -A INPUT -p udp -m 
udp --dport 3478 -j ACCEPTiptables -A OUTPUT -p udp -m udp --sport 3478 -j 
ACCEPT
Now it works for me.
There is may be missing something or useless. But finally I got a working 
solution.I am no WebRTC expert... just a JEE Developer with loves Linux for 
years :)
Any suggestions or hints if somhing is wrong or useless are welcome.
Kind regards
Marcus

Take a look at the kern.log, if your firewall drops sth.
I guess sth. like this would help:

OUTPUT -p udp -m udp  --sport 1:65535 -j ACCEPTiptables -A INPUT -p udp -m

Re: virtual host config

[Marcus Schulz]

Hi Orm,


here is a working  example for Apache webserver. You need the WebSockets 
to be rewritten.
Expecteing the tomcat of your openmeeting installation running in port 
5080 @ localhost.
If your apache is configured for ssl, be sure to add scheme and security 
to your tomcat connector:


 


Apache fragment for vhost:
###  OpenMeetings    ###
## Custom fragment
RewriteEngine On
RewriteCond %{REQUEST_URI} ^/$
RewriteRule (.*) /openmeetings/ [R=301]
RewriteCond %{HTTP:Connection} Upgrade [NC]
RewriteCond %{HTTP:Upgrade} websocket [NC]
RewriteRule /(.*) ws://localhost:5080/$1 [P,L]
RedirectMatch ^/$ https://yourservername.de/openmeetings
ProxyPreserveHost On


  Require all granted
  ProxyPass http://localhost:5080/openmeetings
  ProxyPassReverse http://localhost:5080/openmeetings
  RewriteEngine On
  RewriteRule ^/(.*) http://localhost:5080/$1 [P]


  Require all granted

  ProxyPassReverse http://localhost:5080/idle


  Require all granted
  ProxyPass http://localhost:5080/close
  ProxyPassReverse http://localhost:5080/close


Hope, that helps.

Hello Alvaro,

Yes, me.

I configured SSL Apache straigt forward and then use the PLAIN connector 
of the tomcat. You cannot proxy with an SSL virtual host to another SSL 
connector as far as I know.



use that connector for tomcat:

I would also prefere the icons displaying the current state, not the

My users alaways asked if the mic is off, because there has been a 
little cross.


Thank you all for your great work btw.

Hi all.

Maybe you mean something like that. The first image when the camera

second image when the camera and microphone are off, nobody can

I answered one other thing - the user rectangle volume control should

Hello All,
I'll try to answer in one email :)

- The symbol and the text for leaving the room should be
highlighted (in color?).

Could you please color this using color scheme from here 
https://bootswatch.com/sandstone/

And Share the result as picture?
(I'm not a designer, and have no imagination, but I believe too much 
colors can ruin everything)


- The character > should be inverted in the chat bar. That would
correspond to the same logic as with the new camera and
microphone symbol.

Will do

- The color selection dialog should open near the tools
properties window.
At the moment the color selection appears in the top left corner
and makes long movements with the mouse.

Seems to be opened as expected
Could you re-check with latest version?

- The icons in the toolbar could be a little bit smaler. They
almost touch the chat bar. see attached screenshot.

Same remark as above,
Can you share the of the room with this change?

But this should not slow down the release process.   ;-)

Yep,
Dozens of mosquitos can kill an elephant ... :)))

One last idea - and I understand that I am just a tester / user
of this and that it is your project in which I participate ( I
also participate in spark, hadoop, nutch - i love apache
projects), but since you asked, I would change the color of
everythign that is "ON" or enabled to green and everything that
is "OFF" to red - just like the traffic lights!  For what it's
worth, and I have nothing against the color orange!

Same remark as above,
Can you share the of the room with this change?


This is better - personally I would color the camera and mic
icons that are activated, so they look "ON" - (without the
slash of course) - and to indicate the "OFF" status - it is
fine - with the slash.

For example, when you hover over (or mouse over) the tiny
speaker icon in the dragable user rectangle we see the
orange-colored old-fashioned microphone  image pop-up - this
is excellent. I would also have theat tiny speaker icon in
the dragable user rectangle in orange to indicate its state
is "ON" when it is on - the other two tiny icons (refresh and
minimize) at the top of the dragable user rectangle are fine
in grey since they are settings to change not states and
users know what to expect with them.

Same remark as above,
Can you share the of the room with this change?

This is my advice since you asked - I'm more concerned with
fonctionality! It is working well.

One question - I have tested this extensively in Chrome adn I
notice that if one sets the volume of teh microphone
different than 50 (in the tiny icon in the dragable user
rectangle) -each time I refres the user it si reset to level
50. Is this desired? Wouldn't it be better to keep the last
user volumn settings through a "refresh" since users will
most probably use the refresh to see or hear another user who
may have changed the state of their camera and microphone.
This is just an idea - it is OK as it is since it's easy to
reset it.

Actually I thought of this
BUT unfortunately this is not that easy
Actually there are more than one volume
1) self volume (actually microphone gain)
2) volume for each 

Developing Openmeeting

[Marcus Schulz]

Hi,

I am a Java EE developer and  got interested in openmeeting and maybe I could 
help developing sth, at least I want to take a look at it.
Is there an apache repository for the snapshot / milestone builds like Wicket 
Parent 9.0.0-M5-SNAPSHOT for example, or do I have to all build them first?
Hope the questions isn't too stupid, I did not develop for an apache project so 
far. I use them for years, so I may can give sth, back.


Kind regards

Strange behaviour after restart of my server

I run OpenMeetings M3 on a Ubuntu 18 Server wor two weeks without problems.

Any ideas for further checks  what's wrong?

What kind of limits do you suggest in /etc/security

Hello Marcus,

such topic worth to be moved to dev@ list :)))
I glad you are interested

All necessary repositories are in the pom.xml
All you need is to run `mvn clean install`
you might find this link useful 
https://openmeetings.apache.org/BuildInstructions.html


Wicket M5 is currently being voted, so hopefully i can get rid of SNAPSHOT 
dependencies


feel free to contact dev@ list if you have other questions

Hi,

I am a Java EE developer and got interested in openmeeting and maybe I 
could help developing sth, at least I want to take a look at it.
Is there an apache repository for the snapshot / milestone builds like 
Wicket Parent 9.0.0-M5-SNAPSHOT for example, or do I have to all build them 
first?
Hope the questions isn't too stupid, I did not develop for an apache 
project so far. I use them for years, so I may can give sth, back.



Kind regards

This was the reason why I installed M3 (and installed KMS again), such as

I would say it is weird
All "occupied" resources are at minimum level after restart
Can you do multiple restarts and check if this issue is reproducible?

BTW what version of KMS are you using?

I can't remember I changed anything.
That's in the log of kurento after restart:
