Hello Alvaro,



Thank you for your continued contribution.



Your tutorials had helped us overcome initial hiccups when we joined this 
project in 2014 and ensured we do not stumble thereafter.

Remove User (Non-Moderator) in a Room Session

[Coscend@OM]

Hello Community,



We would like to learn whether

in a Public Presentation Room

the moderator of a Group can remove

a user of the same Group (but non-moderator).



If so, is the red cross button under the user’s name functional in the recently 
released version OM 6.2.0?  All the other buttons seem to work fine.



Thank you.



Sincerely,



Hemant K. Sabat

RE: resize SCREEN (disconnect and connect)

[Coscend@OM]

Hello,



These could be two separate features, perhaps enabled or disabled in adminà 
config for different rooms.



1. Preserving local user-settled size of videos.

Automatic re-connect by user.

Or, a user may intentionally resize or turn off and turn on videos due to low 
Internet speed or to increase whiteboard space.



2. Fixing videos as a pod on window.  Vs. Dragging, placing and resizing 
videos at our will.



Perhaps there can be multiple room templates.



Room Template 1:  Current Presentation room template:  No fixed window position 
for videos. Flexibly drag and move videos to wherever one likes.



For those who need more whiteboard space (extensively require collaboration) 
and use videos limitedly.

Example:  Everyday routinely used by our engineering, marketing and product 
teams.



Room template 2:  Fix video pod position on a window.



For those who use videos more and less collaboration space is fine.



Other room templates:  interview room (no whiteboard collaboration space), etc.



Thank you.



Sincerely,



Hemant K. Sabat

Something like that:

https://nosferatu.g0x.ru/pub/openmeetings/mockups



Algorithm of rectangle packing is debatable. I think it will be better to 
dynamically calculate webcam sizes based on total number of cameras and 
available area size so they are all the same size. And deny any user custom 
movement/resizes. Maybe with exception that user can increase/decrease size of 
specific webcams by factor of 2.

I personally think that it would be nice if OM would have some webcam dedicated 
area without nothing underneath. So the user doesn't ever need to micromanage 
webcam windows manually. They should align and resizing themselves in that area 
automatically by trying to cover it in most effecient way. Like typically all 
other conferencing software does. For example I like how jitsi does it. They 
have sidebar miniature view, tile view and ability to open arbitrary webcam on 
fullscreen by clicking on it. That also solves problem on touch screens which 
doesn't really support window dragging without questionable hacks.



I would love to see some mockup of such layout

for both big and small monitors ...

After the meeting start, everything is good,  all those windows are placed when

But, what we can see is that if any of those 5 users have a bad internet

And then,  his screen (only that user) will become again (after his

If 2-3 users of those 5 have bad connection, it can become really anoying.



I hope it’s more clear.



Yes,

The hotkey I posted should do the following:

1) resize all video windows to be 120x90

2) allign them left-to-right, bottom-to-top



Not sure what else can done :(

One KMS and Coturn for Two OM/Tomcat

[Coscend@OM]

Hello Community,

 

We would like to deploy two OM/Tomcat (on ports 5080 and 5081) with
different customizations/features in the same data center that has one
public IP.  

 

We are seeking insights into these two questions:

 

1. Can both these OMs use single KMS?  If yes, how to configure it in
WebRtcEndpoint.conf.ini?

 

2. Can both these OMs use single Coturn on ports 3478 and 3471?  If yes,
should we use 

 

alt-listening-port 

alt-listening-ip

user1:password1

user2:password2

 

If so, where should we add "user2:password2" to KMS configuration?

 

Thank you.

 

Sincerely,

RE: OM5: Reverse Proxy - CoTURN NAT

[Coscend@OM]

Dear Maxim,

 

CoTURN is installed—we included in subject line of the message—and passing 
trickle ICE test for STUN:3478, but not for TURN:3478.  Could this be an issue?

 

*5.0.0-M2 IS transmitting video or audio to the other users, but NOT at the 
same time—i.e., transmitting only video or audio at any time.  Therefore, 
CoTURN is working and firewall is not blocking.

 

*5.0.0-M3 (build 2367) is NOT transmitting both video and audio.  

 

No configuration changes except SSL and MariaDB (mysql_persistence.xml).

 

If it is not firewall, CoTURN or OM code logic, is there any other area we 
should look at that we are missing now?

 

Thank you.

 

Sincerely,

 

Hemant K. Sabat

RE: OM5: Reverse Proxy - CoTURN NAT

[Coscend@OM]

Dear Daniel,

 

Thank you for the pointer.  Unfortunately, our servers are enterprise-grade 
(meaning prohibitively expensive) and hence, need to have VMs to be 
cost-effective.

 

 

Dear Maxim,

 

After over 50 tests with different configurations of coturn and firewall ports, 
we are now able to stream in intranet as well as extranet:

Videos of all participants

Audio of all participants

 

The issue:  Users can see EITHER video OR audio, but NOT BOTH, AT THE SAME TIME.

We would appreciate any insight the solution.

 



Possible cause

Firewall ports (both hardware and software) are not blocking because the users 
can:

1.  See either video or audio at any time, but not both concurrently.

2.  Giving the same result in the following use cases:

both intranet (two devices connected to one switch, and no router between the 
devices) and 

extranet (router+firewall).

 

We are attempting to refine the logic of methods, variables and their values 
stored in and retrieved from OM database:

activityAllowed, activityToggle, hasActivity, Client set(Activity a), Client 
toggle(Activity a)

Dear Community,

 

We are seeking inputs into the following non-functioning video toggle in a
room.

 

HTTPS Video and audio WAS WORKING in intranet (within NAT-- no coturn, no
reverse proxy) till yesterday.  Today, when we click on video icon in a room
to activate it, nothing happens.  After clicking to toggle audio, when we
click to toggle video, a red cross appears.  But there is no video or audio
frame that appears on screen.

All relevant ports are open in OS.  Has any library changed in docker,
kurento or video-related program in the last day or two?  We are using
OM5.0.0M2 binary from OpenMeetings Web site.

 

We have reinstalled all of these today, but nothing seems to solve the
issue.

I don't have CentOS8 so I need detailed description of

what do you mean by "Environment is CentOS 8 (using docker) and MariaDB 
10.3.x"? (OM is java application, it doesn't require docker to be able to run)

 

So could you run "vanilla" OM5 (without any other services, proxies, 3rd 
parties etc.) and check it it works for you as expected? i.e. both startup.sh 
and shutdown.sh run as correct user do it's job?

 

If yes - add changes one by one and continue checking

If not - compare with "vanilla" Tomcat9 - what is different :)

baby steps :)

Dear Maxim,

 

I am sending this to users, but we think one possibility (not confirmation) is 
this error is related to OM5 code [1].  There is a method in OM5 that is 
triggering memory leak while shutting down Tomcat.  The most common reason is 
something hanging or delaying in Web application initializations [2]. This

RE: OM5: Reverse Proxy - CoTURN NAT

[Coscend@OM]

Hello Maxim,

 

Are serving HTTPS pages from Tomcat?  That is, certificates are input in 
server.xml including port 5443.

 

 

Hello Rene,

 

Thank you for the insight.  Yes, ports open TCP 3478 UDP 49152-65535 for Coturn.

 

Sincerely,

As far as I understand OM is available at 443 (via reverse proxy)

 

Any errors in browser console?

Have you open port 5443 (Tomcat-https-Port)? 3478 and the port range is for 
Coturn, I think.

RE: OM5: File Upload Error

[Coscend@OM]

Dear Maxim,

Thank you for your pointer.  Here are two cases and results:

*   Yum install ImageMagick-6.9.10-75  
File upload SUCCESS.  

*   Compile from source ImageMagick-6.9.10-75:  
file upload FAIL.

Both cases create the same binaries (convert, etc.).   So, our file upload 
error is due to a missing configure options we are using during compilation.
---

Out of curiosity, would you happen to know any library we might be missing in 
our source compilation that might be causing our source compiled ImageMagick to 
not upload files?
 /etc/*.xml files are not created in our compilation from source.  

Our compile options include:
hdri 
modules
perl   
static 
gnu-ld 
quantum-depth=16 
bzlib   
autotrace   
djvu
dps 
fpx 
fontconfig

I'm surprised that following that tutorial, made for CentOS 7, you can

install kms on CentOS 8, 'cause docker installation give to me errors of

dependencies.

 

Ok, i've installed it with this commands, on CentOS 8:

 

 

sudo dnf config-manager 
--add-repo=https://download.docker.com/linux/centos/docker-ce.repo

 

sudo dnf install --nobest docker-ce

 

sudo systemctl start docker.service

 

sudo docker run -d --name kms -p : --mount

type=bind,source=/opt/open502/webapps/openmeetings/data,target=/opt/open502/webapps/

openmeetings/data kurento/kurento-media-server

 

sudo docker start kms

 

...and so the command: ps aux | grep kms

 

...result: kms

Hello OM Community,

 

May we seek your advise on how to navigate the following hurdle we are facing 
with OM5 installation in CentOS 8?

 

We followed Alvaro’s OM5-CentOS 7 tutorial.  We are at the following step:  
Kurento Media Server installation

install kurento-media-server:  

sudo docker run -d --name kms -p : --mount 
type=bind,source=/opt/open502/webapps/openmeetings/data,target=/opt/open502/webapps/openmeetings/data
 kurento/kurento-media-server

Run kurento-media-server, wich name its kms:  

sudo docker start kms

 

When we do 

ps aux | grep kms

there is NO kms process listed.

 

How to find out what could have gone wrong?  How to identify the cause of the 
error?

 

Additional:

1.  OM5 is running fine without video and audio.

2.  Docker-ce, docker-ce-cli and containered.io were installed successfully.

 

 

Thank you.

OM5: File Upload Error

[Coscend@OM]

Dear OM Community,

 

May we seek your guidance on the following "File upload error" we are facing
with OM5.0.0-M2?

.JPEG, PDF, MS Office documents:  gives DELETED image

.JPG upload is successful, but has errors in logs

.PNG file upload is successful.

 

Does this suggest that conversion is not successful?  For convert command,
we have added a symlink to magick binary in ImageMagick-7.0.9.  There is no
convert in ImageMagick 7.  There is no policy.conf in ImageMagick-7.
OpenOffice-4.1.7/program/soffice.bin exists.

 

 

Environment:

CentOS 8

ImageMagick 7.0.9 

Ghostscript 9.50

OpenOffice -4.1.7

MariaDB 10.3.18

 

Below are the logs during upload of:

RE: sharing programs/desktop

[Coscend@OM]

Hello Friends,



Here is a thought.  Perhaps it can be offered as an option in admin -> 
configuration

Automatic

Manual (default)



Both are useful in different contexts.  Automatic is good for users that use it 
only for screen sharing such as troubleshooting / IT training.



Manual (default) is for audience that use other features in addition to screen 
sharing.  Screen sharing will consume bandwidth and will slow down the other 
features.



Thank you.

Hello Maxim,

with the "black screen" we supposed that. But, I say that, in sharing the whole 
screen is OK.

With the "sharing-icon" its a bigger problem (for me). The most users of 
present are so sensitized that they not click.
In the past I spent a lot of time to explain when I want a remote-access with 
TeamViewer. The remote-access is not the
problem, they need help, its the question (under windows) at the start from 
TeamViewer ("UAC") to allow the access.
This global UAV-warnings are so miserable.  Some of users refuse to click on 
"Yes".
(OK, it is clear that TeamViewer want Admin-rights.)
I hear from a lot of people that the IT-Department of their organisations give 
directives to not-click in a browser on anything
which is not well known.

When it is possible it will be very nice to open the sharing-screen 
automatically when the moderator give it free. In my opinion
the moderator featured his presentation himself, and the user looking without 
interaction.

Whats the meaning of the other?

Best regards,

René

Hello Rene,



I'll try to answer point by point :)



"older Delphi-program its not possible, the client only receive a black screen" 
- actually browser performs screen-sharing

So i guess there are some limitation on Windows (most probably something with 
graphics/overlay)



"when I transfer the screen in the client-browser only the sharing-icon 
appears" - right now this icon blinks to attract user's attention

Screen-sharing window is usually huge this is why user can close it any time 
and re-open by clicking same icon

Maybe sort of "text info popup" can help?

I try to share a program.

With an older Delphi-program its not possible, the client only receive a
black screen. We have this one year ago and
you said that came from Kurento. But thats no problem, when I select the
whole screen it works. Its not the best solution, but it works.

One thing that bother is when I transfer the screen in the
client-browser only the sharing-icon appears.
I (moderator) have to communicate that the person who view the
presentation have to click on it and allow the question.
In germany no user click on an question to allow anything - I have a big
problem with it.
Many persons not find the icon (right top corner is difficult to find)
or they dont allow and switch off.

Please, can you find a solution that the sharing-window appears without
click on the icon? I mean, the moderator show what he want.

Best regards,

RE: [DISCUSSION] shall attendees be removed from the room when the time is over

Subject: RE: [DISCUSSION] shall attendees be removed from the room when the

Hello,



Here are a few additional perspectives based on our use cases.



This feature will be useful in at least these cases:

1.  Remote patients from two different locations consulting the same doctor 
in the same room.  The doctor should be able to remove the previous patient 
from the location 1 before allowing the location 2 patient to join.

2.  Students from two different locations being taught by the same tutor in 
the same room.

3.  Employees from two different locations having a performance review 
meeting with the HR manager sitting in the corporate office, all joining the 
same room.

4.  Sales people having meetings in one room with different channel 
partners in the same room with the same presentation materials.  The channel 
partners should not overlap due to sales commission issues.

5.  CEO having a board meeting with different committees of the board.  The 
committee members come and go at specific intervals in the same room.  These 
different committees should not hear each other (such as finance and audit 
committees).



The moderator (doctor, teacher, HR manager, sales person, CEO) will remain in 
the room.  Other participants may change.  The moderator may choose to keep 
select participants (nurses, co-tutors, co-managers, channel partners, board 
members), if required.



Thank you.

If this should be implemented, it should be an "per appointment option" and

RE: [DISCUSSION] shall attendees be removed from the room when the time is over

[Coscend@OM]

Hello,



Here are a few additional perspectives based on our use cases.



This feature will be useful in at least these cases:

1.  Remote patients from two different locations consulting the same doctor 
in the same room.  The doctor should be able to remove the previous patient 
from the location 1 before allowing the location 2 patient to join.

2.  Students from two different locations being taught by the same tutor in 
the same room.

3.  Employees from two different locations having a performance review 
meeting with the HR manager sitting in the corporate office, all joining the 
same room.

4.  Sales people having meetings in one room with different channel 
partners in the same room with the same presentation materials.  The channel 
partners should not overlap due to sales commission issues.

5.  CEO having a board meeting with different committees of the board.  The 
committee members come and go at specific intervals in the same room.  These 
different committees should not hear each other (such as finance and audit 
committees).



The moderator (doctor, teacher, HR manager, sales person, CEO) will remain in 
the room.  Other participants may change.  The moderator may choose to keep 
select participants (nurses, co-tutors, co-managers, channel partners, board 
members), if required.



Thank you.



Sincerely,



Hemant K. Sabat

This discussion was started to get clear understanding if this should be 
implemented or not

IMO the feature is questionable, so I need advise ...

Hi Maxim,

this is not our use-case, but I think there is no need to empty the room 
automatically. If needed it could be done manually.

If this should be implemented, it should be an "per appointment option" and 
default should be off.

Should it be default behavior for any appointment?
Should it be customizable? If yes: should it be global option for entire
installation or should it be "per appointment" setting?

Hello All,

Some time ago this JIRA was filed:

It states that user can stay in the room after meeting time is over

Would it be OK to force remove all users except organizer from the

RE: Import File Explorer issue in 4.0.5

[Coscend@OM]

Dear Community, 

 

We did some more research to help solve the import database issue.  Is the
following issue related to this code:
https://github.com/apache/openmeetings/blob/4.0.x/openmeetings-install/src/m
ain/java/org/apache/openmeetings/backup/BackupImport.java#L1040? 

 

Issue:  After importing 3.3.2 database into 4.0.5, in the File Explorer UI,
multiple folders in Room Files are visible.  But NO files are inside any of
these folders.  On the server, the files are present and verified.

 

Thank you.

RE: Whiteboard Tool Layout: ID Selector Effect

[Coscend@OM]

Dear Maxim,



Thank you for helping us learn about the concept of “adding a CSS id and class 
selector as a template in Java programs”.  This conceptual learning not only 
helps us refine our OM instance as below, but also complements our use of chain 
id and class selectors and combinators in 7 other Web-based communications and 
collaboration products.



Your pointer [1] solves our toolbar positioning requirement.

Hello Alex,



Here is a vector to assist you.



Perhaps you are using a reverse proxy server in front of your OM installation.  
If so, you may want to configure the proxy server.  Here are a few examples 
courtesy others:

RE: Device list problem

[Coscend@OM]

Dear Maxim,



Pursuing the discussion on the permission request from OS device drivers to 
load and allow access to devices into browser,



Can you point us to the 5.0.0 JS code you are referring to as a Web link?  We 
have written code along the lines below to seamlessly access media streaming 
sources by loading device drivers from the OS and can add or build upon your 
5.0.0. code?  Of course, if you need to review our code snippet, we would be 
happy to share as well.  (We are not sure whether this technical post should be 
in user@ or dev@).



We are keen on learning, whether your code:

· uses the standard getUserMedia() API?

· enables setting of media constraints while loading device drivers 
from OS, in addition to selecting media streaming sources?

· provides access permission from device drivers persistently?

· takes care of cross-origin calls that are deprecated?

· is limited by protocol-based calls:  HTTPS, file://URL ?



Thank you.

In our case the person was using a laptop with mic, speakers and webcam 
built-in. So there wasn't an issue of devices not being connected or recognized.



There was a discussion recently about some related issues. I think the best 
thing is for all new users to use setup link before entering their meeting 
room. Can be done from the dashboard (see below) or by providing new users with 
a link like the following:  [

I have seen this on Chrome with OpenMeetings Version 4.0.3.
It seems that this problem happens only the 1st time you set the webcam and mic

Have some of you the same problem ?

Dear Darshit,

you need to enable the RTMPS in /conf/jee-container.xml.
It is there already but commented out.

Also make sure that the keystore and truststore are correctly labeled (I had 
problems with them in the default configuration) and have the correct passwords.

Cheers
Christian

RE: How to run openmeeting on RTMPS with nginx in frontend

[Coscend@OM]

Dear Christian,

Could you help us understand a little more about the following scenario?

In Darshit's case, it is Nginx https + OM http.  In such a case, the SSL will 
be terminated at Nginx.  Only HTTP requests will be sent to Tomcat.  In 
addition to Admin ->Config (flash.secure = true, flash.secure.proxy = none), 
does Darshit have to do the following:

1. red5/conf/jee-container.xml:  UNComment Tomcat with SSL enabled section
2. deal with keystore and truststore?

Thank you.

Sincerely,

Hemant K. Sabat

RE: Device list problem

[Coscend@OM]

Dear Ludovic and Dan,



The dropdown device list remains blank when the browser cannot connect to the 
active device drivers in the OS properly before loading the page.



Solution to this issue:

· Reload the browser.

· Restart the computer.



Better solution:  Connect the mic, speaker and webcam to the computer before 
turning on the power of the computer.  This issue will not occur.



Thank you.

I have seen this on Chrome with OpenMeetings Version 4.0.3.
It seems that this problem happens only the 1st time you set the webcam and mic

Have some of you the same problem ?

Hello Christian,

Would you be kind enough to share the Apache SSL configuration?  We are facing 
issues in connecting through “proxy HTTPS + OM HTTP”.  We are using a different 
proxy server, but can learn from your Apache configuration to adapt to our 
proxy.

How is your configuration different from this:

I'm afraid in case of full secured proxied configuration you need to use RTPMTS 
(tunneled secured RTMP) example of RTMPT config can be found in mail archives,

Is your setup:  Reverse proxy HTTPD + HTTP OM?
Are you converting HTTPS --> HTTP in front of reverse proxy HTTPD?

If so, did you happen to review the log files of your OM installation?  And the 
access log files of your HTTPD installation?

Thank you.

I am resending same message because web mailing shows improper format of

http proxy works OK as it redirects domain root requests / to server internal

It would be kind if you could provide me with a sample code so I can adapt
it to my ssl.conf directives and get ride of this CSRF blocking problem.

Dear Hemant,

I came across your profile over the Apache OpenMeetings page while searching
to fix a problem I have actually after installing Apache OpenMeetings to
ease the work of our remote teams over the internet.

The local installation on CentOS works at
http://localhost:5080/openmeetings.

But when I want to access it over SSL (https) I get :

 

Possible CSRF attack, 

request URL: http
<http://IP:ADDRESS/openmeetings/wicket/bookmarkable/org.apache.openmeetings.
web.pages.auth.SignInPage>
://IP:ADDRESS/openmeetings/wicket/bookmarkable/org.apache.openmeetings.web.p
ages.auth.SignInPage, 

Origin: https:// IP:ADDRESS, action: aborted with error 400 Origin does not
correspond to request

 

Any help to fix this would be very appreciated.

Cheers,

Ahmed

Who’s your root authority? Be sure that it’s trusted. Otherwise by default it

Is it a self signed certificate, and the certificate and root CA are on both

Hi, Maxim,



I used a friend's computer to check. He has an old version of firefox. It 
works. But I have the latest version of Firefox. I don't know why it does not 
work. Did you use the latest version of firefox? I am using letsencrypt 
certificate, so it is real certificate.

I will try client debug mode.  What do you mean Net-test tool? What is the 
purpose of net-test tool?

Hello Tom,



great your installation is now works with Chrome.

I just have checked with FF - everything works as expected, maybe the issue 
with certificate? Chrome and FF uses different certificate storage  Are you 
using "real" of self-signed certificate?

Maybe "client debug mode" can give you more info on what is wrong 



I have checked Net-test tool, it is now works with RTMPS native (build #90+

RE: Camera blocked

[Coscend@OM]

Hello Anis,



Which browser are you using?  If Chrome, it needs to be HTTPS only.



If you are using other browsers, try

1. Checking whether camera is accessible with other video programs such as 
Skype, Hangout.  Disable / sign out of these programs.

2. reload the browser.

3. Reboot the computer with the webcam, mic and speaker connected



Your OS and browser need to recognize the connected imaging devices for these 
to appear in your dropdown list.  If the imaging devices are recognized, you 
will see a preview of your video.



Thank you.



Sincerely,

Hello Tom,



Native

-

File: conf/red5-core.xml

Enable:   rtmpsMinaIoHandler and rtmpsTransport



+ better performance due to self-reliance

- Combines RTMP with SSL à hard to solve issues.





Tunnel: tunnels through HTTPS

--

File:  conf/jee-container.xml

Enable:  Tomcat with SSL enabled



+ easy to handle

- One protocol relying on the other’s performance.

https://om.alteametasoft.com:8443/next  (powerfull server)
https://demo-openmeetings.apache.org/openmeetings (server without enough 
resources :) the SLOW one :)) )

Or test locally using nightly build: 
https://builds.apache.org/view/M-R/view/OpenMeetings/job/openmeetings/



Here is the testing plan you can use: 
http://openmeetings.apache.org/ManualTesting.html



Thanks in advance!

RE: 3.3.2 Snapshot: Login not Posting via Proxy

[Coscend@OM]

Dear Maxim,



Based on your vector, we found out the cause of the error (see below).  Your 
further guidance would help us resolve the error.



Cause

-

In 3.3.0, proxy server is capturing JSESSIONID.  In 3.3.2, proxy server is NOT 
ABLE TO capture JSESSIONID.





QUESTION



Could you please advise in publishing session cookie, how is OM 3.3.2 different 
from 3.3.0?  Proxy server logs are below.  Thank you.





Proxy server logs

-

In OM 3.3.0, proxy server is capturing JSESSIONID in each line.

Is it the case?

RE: CLI Install: Libraries Path

[Coscend@OM]

Dear Maxim,



We would like to create a template of standard config values (including path to 
libraries) that could be input into OM DB through

./admin.sh  -i –v …



Will option 1 below work?  Is option 2 correct understanding?



Option 1:

CLI:  ./admin.sh  -i –v -swftools_path=/usr/lib64/ImageMagick-6.7.8 …





Option 2:  using -file option and provide backup.zip with all config values



CLI:  ./admin.sh  -i –v –file backup.zip



In backup.zip, have a filename config.xml with path to libraries.

  

 

 

 

 

 

 

 

  







Option 3 (good to know, but not our use case):  make all tools available in the 
PATH in OS and leave all these paths empty in OM.





Thank you.



Sincerely,



Hemant K. Sabat

RE: 3.3.2 Snapshot Video Not Visible in Chrome

[Coscend@OM]

Dear Maxim,



Thank you for promptly pointing us to the cause of our issue.  That saved us a 
lot of scratching of our heads.  It has been a pleasure working with this 
community.



On the lighter side (pun intended),



Question:  What would we have done if Maxim did not exist?



Answer: We would have been forced to:



git clone 
https://git-wip-us.apache.org/repos/asf/‘MAXIM’S_ATOMS_AND_MOLECULES.git’

mvn clean install -P allMAXIM

Web install and configure ‘Maxim’ binary



Result:  All OM questions answered.



Thank you.

2. add  to allowed site list in Java Security.

3. Check the  value in public_7.jnlp in a text editor.



Thank you.

Dear Alekhya,



Assuming you are using Windows on your client / user computer, two things could 
help you



Check whether you have listed in Control Panel -> Programs -> Java 8 Update 144?

Check in C:/Program Files /Java ->jre1.8.0_144 directory?



You can do similar ones if you are using Linux.



Thank you.

Dear Maxim,



Courtesy your supportive comments, we were able to solve this issue.



The Web session was not being stored for the user.  This Web session temporary 
storage was probably introduced in 3.3.0, and was not there in 3.2.1.



Thank you.

RE: White screen after logon

[Coscend@OM]

Dear Vladimir,



Assuming you are using OM 3.3.x+, perhaps the following vectors will help:



Are you using a proxy server?

1. If yes, what security headers have you configured in your proxy server?

2. If you are not using a proxy server, are you using the default security 
headers of OM?



Thank you.



Sincerely,

Hello!

The problem happens while I connect to OM from different subnets towards IP OM. 
For example IP OM is 192.168.1.4, and I nit eed connect from 10.10.10.4. 
Routing between networks is set and I see login screen, but after logon it 
transforms into clean white screen with small chat window in right corner.

I launched network testing, 5 green squares.

What's wrong?

RE: HTTPS with installation from source files

[Coscend@OM]

Dear Maxime,

You can find the summary steps at:
http://openmeetings.markmail.org/message/xrxgzyaf2ey7belk?q=%5BANNOUNCE%5D+H
TTPS+is+now+required
With third party certificate (Letsencrypt), the lock icon on browser will be
green automatically.  So, no need of Step 2.

Detailed steps, including the location to place your certificate, do other
steps and enable HTTPS and RTMPS (red5.properties):
https://openmeetings.apache.org/RTMPSAndHTTPS.html

Thank you.

Sincerely,

Subject: HTTPS with installation from source files

Hello,

I would like to know how to add a letsencrypt cert to my OM server knowing
that I installed it from sources (so files are not at the same places as
from normal installation).
In fact, which file of the webserver should I modify to have the green lock
? Do I have to reinstall the server with modifications or can I do it
directly ?
I have already put my certificate in the java cacerts and modified
jeecontainer.xml and config to replace http and port 5080 to https and port
5443.

Thank you in advance.

Best regards.

Maxime

RE: Proxy config for OM

Dear Phong,



Assuming your rest of the configuration (OpenMeetings, router, Web application 
firewall, OS) are accurate, this might help enable WebSockets via proxy server:

Thank you.

Hello,

thank you for the link.
I try to checkout it with SV in Eclipse - but I get an error.

After that I try to import the unpacked zip-file in Eclipse. I see the 
openmeetings-structure
but when I try to make a jar I get errors that he miss a lot of things (e.g. 
libaries).

My idea is that I checkout with SVN. I hope that I wil have then all needed 
files.

Best regards,

RE: [DISCUSSION] HTML5 whiteboard for 4.0.0

[Coscend@OM]

Dear OpenMeetings Community,

It would be great to learn about Ed's ideas on "function hub".  In the 
meantime, as requested by Maxim, here are our thoughts about the Page Navigator.

The salient part is the navigator appears and disappears in "real-time", 
thereby making the UI more user friendly.  That is,
1. when a file is displayed and disappears when the displayed file is removed.  
This gives more working space for other relevant items.
2. only on the whiteboard where there is a displayed file.

Perhaps we could have a similar "real-time" expandable / collapsible frame of 
the
1. Users panel:  Have a small "Users" icon with a tooltip.  When we hover on 
this icon, it will expand to open the user panel.  When we move out of the 
panel, it will collapse.  Ditto for Files panel and toolbar below.
2. Files panel

This could possibly be done by combining
1. https://api.jqueryui.com/scale-effect/
2. Hover: frames and divs remain inside of their own relative area.  Animate 
from (0,0) position both minus values so that they expand towards bottom right. 
 z-index of expanding block will be higher than surrounding so that it appears 
on top.
$(".img a img").hover(function() {
$(this).closest(".img").css("z-index", 1);

// this is where the popping out effect happens
$(this).animate({ height: "800", width: "200", left: "-=30", top: "-=30" }, 
"fast");

}, function() {
$(this).closest(".img").css("z-index", 0);
$(this).animate({ height: "20", width: "20", left: "+=30", top: "+=30" }, 
"fast");
});​

Thank you.

Sincerely,

Hemant K. Sabat

RE: Re: Screen Sharing too slow

[Coscend@OM]

Dear John,



Perhaps the following information could help you find the cause:



· Is it upload or download speed that you are referring to?

· What is the processor of server where OM is hosted:  RAM, CPU?

· What quality of resolution you are using for screen sharing?

· What size of the screen you are using?

· What video resolution you are using along with screen sharing?

· Where is your service hosted, office or residence?

· How many whiteboards you are working with during the session?



Thank you.



Sincerely,



Hemant K. Sabat

What Maxim meant was:



1. Screen-sharing and audio are two SEPARATE features (and program

2. Users can use both as well as chat and whiteboard and zoom.  But their 
smooth functioning is dictated by your Internet speed.



NORMAL screensharing requires a minimum of 1 Mbps UPLOAD speed per attendee.

NORMAL video requires 500Kbps upload per attendee.



Do you have UPLOAD speed of at least 1.5 Mbps per attendee.  So, if you have 5 
attendees, you may need around 4 Mbps upload (=1.5+0.5*5)





Thank you.

RE: OM 3.3.0: IllegalArgumentException Upon Entering Room via Proxy Server

[Coscend@OM]

Dear Maxim,



Thank you for guiding us to enable maximum logging to identify the cause of 
network connection failure in OpenMeetings service.  We enabled advanced 
logging in our data center firewalls, namely Proxy server, network hardware 
firewall, Web application firewall and load balancer.  This helped identify the 
mis-configuration in this data center infrastructure.  After suitably modifying 
the configuration, vanilla OM 3.3.0 is working fine in our data center network.



Your prompt responsiveness allows OpenMeetings open source project to be a 
standout.



Post this successful test, we added our extensive customizations (to attract 
investors, customers and partners), built our custom version of OpenMeetings 
and launched it into production for use by our partners, employees and 
customers.  Thank you.



Sincerely,



Hemant K. Sabat

The issue is not reproducible using "vanilla" OM

This means it is caused by your proxy server (apache, nginx etc.)



so you have to enable detailed logs at your proxy server

especially rewrite related logs

 That means that it is a bandwidth issue?. The problem with Medium quality is 
that the screen is smaller. Is it possible to reduce the screen quality without

RE: OM 3.3.0: CSRF Solution via Reverse Proxy Server

[Coscend@OM]

Dear Maxim and OpenMeetings Community,

Just following up to see if anyone can provide us sample lines of a working 
configuration of reverse proxy and rewrite rules to access OM 3.3.0 through a 
proxy server.  Relevant "CSRF+security headers+WebSockets" configuration of 
Apache HTTPD or NGINX or any other Web server load balancer will help.  We will 
modify it to suit our load balancer.


We have added several of the following options, but OM is being blocked by CSRF 
security header.

We have added the following headers options to proxy:
X-Content-Type-Options:  nosniff
Content-Security-Policy: default-src 'self'; style-src 'self' 
'unsafe-inline'; script-src 'self' 'unsafe-inline' 'unsafe-eval'
Strict-Transport-Security:  max-age=31536000; includeSubDomains; preload
X-Frame-Options: DENY   
X-XSS-Protection: 1; mode=block

RE: help configuration smtp server

[Coscend@OM]

Hello Maxime,

In the spirit of assisting you, here are a few vectors to resolve your
issue:
Issue:  "unable to find valid certification path to requested target
at com.sun.mail.smtp.SMTPTransport.startTLS"

Suggestions:
1.  OM configuration issue:
Configure Admin -> Configuration

Smtp_server:  this is the smtp server to send messages.
Smtp_port:  this is the smtp server port normally 25 or 80, if using no SSL,
otherwise 443 if using SSL encrypted e-mail.
System_email_addr:  all sent e-mails by the system including invitations
will have this address:  
Email_username (System authentication email username):  your e-mail's
username:   or on how your third party e-mail client is configured.
Email_userpass:  the password of your e-mail's username
Mail.smtp.starttls.enable:  0 (if above 25 or 80) or 1 (if above is 443)
Enable TLS 1=true, 0=false


For example, in GMail,

Smtp_server:  smtp.gmail.com
Smtp_port:  Port 465 (SSL required)
Port 587 (TLS required)

2. Additional:  Firewall 
Open OS and software firewall SMTP ports.  
Set hardware firewall policies NAT allow from your server to WAN.

Thank you.

Sincerely,

Hemant K. Sabat

RE: No sound in the room

[Coscend@OM]

Hello Anis,

 

Perhaps the following might help:

1. When you are running OpenMeetings, is Skype, Viber or any other audio 
program also running in the background?  You can see whether they are running 
in System Tray (bottom right corner) of your taskbar.

2. Microphone is made accessible by your browser.  While Skype, Viber are 
desktop programs, OpenMeetings is Web browser-based.

3. Recording device:  Just to double check, set the microphone you are 
using for OpenMeetings to default.

 

Thank you.

 

Sincerely,

 

Hemant K. Sabat

Hello Vital,

Yes, in 3.2.x.

Video and whiteboard use Flash technology.  Rest is HTML5.  Perhaps there is
a way to extend the canvas of one beyond its frame to the other.  Perhaps
this could be accomplished by superimposing layers, one layer used for each
frame.

 

Thank you.

Hello,

 

I'm back with OpenMeetings, I've just installed the latest version and I see
that many things have changed.

Thanks Maxim for all the work.

 

I've one question : is it normal (and if 'yes' then why?) that the video
window cannot be placed on the far left side of the screen (where there is
nothing) like in previous versions.

I can't put it anywhere else than on the whiteboard and it is disturbing
because in the case of a Powerpoint presentation, it takes an unnecessary
space.

 

Thx,

 

All the best,

Hi,

I installed om 3.21 on an ubuntu 16 LTS, following Alvaros perfect installation 
guide - and all worked fine. :-)

Then I decided to update and upgraded the os because there where some new 
packages.

After that, the uploaded documents are nont shown on the whiteboard. The 
documents are uploaded without errors.

Can anyone give me some hints to restore the functionality.

In which log I can seek for the problem.

We are unable to “cleanly” load and play audio files in 3.2.2/3.2.1.  

 

(-) for FAIL and (+) for SUCCESS

---

- While uploading an MP3 or M3A audio, it gives a file processing error.  

- It shows up in the File Explorer with an error sign.  

- When we drag it to the whiteboard, it shows a deleted jpg image.

+ When we play it, it plays perfectly.

 

Are we missing something?

RE: [DISCUSSION] HTML5 whiteboard for 4.0.0

[Coscend@OM]

Dear OpenMeetings Community,

 

Two thoughts to consider:

1. Perhaps we could add a “double left arrow” left of the Whiteboard tab to 
collapse the Left Panel (Users/Files).  This will help expand the Whiteboard to 
full screen, as it was in 3.1.x.  Also, perhaps this can be forced on all 
attendees by Moderator.

2. Regarding the screenshot created by Denis and forwarded by Maxim 
(https://www.dropbox.com/sh/mg4rszx2j8xgcoa/AAACBWg8E73TiB9rYDi6vzR6a?dl=0):  
The left vertical column containing icons (Users/Files/Chat/Activities) is 
unused.  Perhaps we could make that panel horizontal as it is in 3.2.x, except 
remove the labels and add only tooltips.

 

Thank you.

 

Sincerely,

 

Hemant K. Sabat

"sketchpad" provides zoom as part of the toolbar

and toolbar is more compact, this is what I like, current toolbar is too big 
IMHO, i would add grouping to it or change it to be more compact

 

1) Actually I guess toolbar at Denis'es screenshot is the same as on demo

it look smaller cause screenshot is 1920x957px :)

 

2) it is just an idea, I would prefer normal horizontal toolbar (maybe without 
text) due to it will take less width

 

currently we are collecting user input :)

Maxim--which aspect of   
https://sketch.io/sketchpad/ are you saying we could implement? I am confused.

 

Also, on the dropbox sketches provided by Dennis, I see two major changes:

 

1. Smaller toolbar (right side of screenshot) which I like.

2. Vertically aligned user's area (far left of screen). What is the reason for 
doing it this way? And what questions/problems remain to be answered about this 
design?

 

I'd like to contribute to this discussion if I understand the remaining 
questions.

 

Thanks!!

Hello Denis,

 

Maybe you have free time to help with design of new room?

 

We need to put scale and goto/prev/next page somewhere

And I believe we need to change WB toolbar to be more compact

 

Additional requirements: 

1) we need a way to display Chat and WB same time 

2) we need a way to display Activities and WB (and Chat) same time

 

I see no places where to put it :(

 

Thanks in advance

Hello Peter,

 

just have checked, the issue with NullPointer is not reproducible locally :((

can you please run "svn status" to ensure no java files are locally modified?

 

Could you additionally check the logs, maybe you have any other warnings/errors?

RE: 3.2.1 Upload Profile or Image

[Coscend@OM]

Dear Maxim,

 

The issue we are facing: in the same server, 

1. everything works with 3.1.5.

2. 3.2.1 does not list in File Explorer, and display PNG and BMP files.  
Everything else works (GIF/JPG/DOC/PPT/XLS/PDF).

 

To isolate the issue, could you please let us learn the following: Is there any 
difference between how 3.1.5 vs 3.2.1 processes files with regard to how they 
upload and display images on whiteboard?

What is in the process flow that we are missing?  It only requires “convert” 
library of ImageMagick.

org.apache.openmeetings.core.data.file.FileProcessor.java 

org.apache.openmeetings.db.dao.file.FileExplorerItemDao.java

 

 

We understand DownlaodHandler.java and uploadWindowExplorer.lzx were removed in 
3.2.x, but should they affect PNG and BMP file upload and display?

 

 

Thank you.

 

Sincerely,

 

Hemant K. Sabat

Here are the use cases we tested in the save server.
3.2.1 (General Release) ---
Loads DOC/PPT/XLS/JPG/HTML/TXT/PDF.
After first upload, it says "Upload starting", even though uploaded file can be 
seen when clicked on 'close".
Does NOT upload PNG files.  It stops after ”isAsIs: false"

In 3.1.x on the same server, everything (PNG/JPG/DOC/PPT/PDF/XLS) works fine.   
Below is the log.
