 Although there seems to be a KMS heartbeat reconnection issue that I have 
 not seen before:
 https://issues.apache.org/jira/browse/OPENMEETINGS-2735
 
 And during the attempt to record on Safari there was some errors. But that 
 was related to recording functionality. It did work in the end but there 
 were a few exceptions and the first attempt failed. This might be worth 
 investigating in another thread/jira.

Re: iPad won't load OM

[Denis Noctor]

Hi there Dan, as silly as it sounds... is it possible that the iOS version on 
the iPad does not support WebRTC?... which was introduced only a few years 
back. It is best to state exactly what model, what max iOS level is supported 
on that device and so on.

Over the weekend, I will compile a list of devices that are not supported, long 
over due.

Regards Denis.

Re: Kurento on a separate server

[Denis Noctor]

Thanks Sebastian - forgot about the whole Coturn / Turn sever side of things... 
which I’d sorted a long time back... but originally on the same server... I 
have been a tad obsessed with the KMS side of things. Thanks again. Back to the 
drawing board...

Kurento on a separate server

[Denis Noctor]

Hi there guys. Hope all is well. Still a lot of interest out there regarding 
clustering and so on and a lot of great questions and feedback. Thanks to Maxim 
and Sebastian.

Million dollar question of the day. How does OM integrate with Kurento? If I 
decided to host Kurento Media Server on a separate server what configuration 
changes / files etc would I need to change on my OM setup for them to 
communicate with each other properly?

Existing setup is still on OM 5.1.0 (I know, I know), Ubuntu 18.04,  OM and KMS 
currently on same server (standard installation). Apologies in advance if this 
is considered a dumb question... but I am still looking into the whole nuts and 
bolts of the architecture of this and hopefully might be able to give 
additional feedback.

All the best.

Re: Audio on iOS

... yes, Ali... but as I mentioned... wouldn’t be sufficient enough for general 
user feedback... while users “may” use OM from their iOS... correction... 
mobile iOS device... they don’t experience the same desktop experience. Anyhoo, 
I will look into this more tomorrow... by the way, I wasn’t the one who opened 
this thread. Nighty night.

 I had no chances to investigate this issue since I don't have iOS devices 
 :(
 I'll take a look at the MiroTalk code :)
 I would appreciate if you can share JS errors from iOS devices :)
 this will help to reduce the amount of work need to be done :)

Re: Audio on iOS

[Denis Noctor]

Possibly on a earlier version? there was an intermittent issue on a 
particular iOS versions last year. Earlier generations of iOS devices will not 
work due to not being able to upgrade to current versions (including WebRTC). 
Check thread.

Re: video sharing

[Denis Noctor]

The only time I’ve experienced a student not being able to view a video is when 
they’ve entered a room after the video has already commenced.

Re: video sharing

[Denis Noctor]

It will play on their screen alright but can only be initiated / controlled by 
the moderator. However enabling presenter tool to students will give them 
access to the video controls also. Would love to see a volume slider added as 
video and audio files are much louder and sometimes catch students by surprise 
:)

All the best,

Re: Video sharing from a link

[Denis Noctor]

No. But you can share a link via the chat box. If I require a YouTube video, I 
usually use an online video converter, download the video and then reupload it 
to a folder on OM and then drag and drop etc.

Re: Some uploads - error converting - file not found

[Denis Noctor]

Here’s my two cents worth on this. As you mentioned “some” I would refrain from 
uploading large pdf files... I am referring to files with a large quantity of 
pages... which will require more ram. If it is a high quality layered pdf, I 
would also suggest flattening it with whatever pdf program you use before 
uploading. Many pdf programs also offer the option of saving a file into 
individual pages which I then upload into a folder, making it easier to drag 
and drop individual pages onto a whiteboard... and as a result making it easier 
to give presentations / classes etc especially if you are adding notes and 
so on to the whiteboard.

Regarding PPT files... I would also be mindful of power point files that 
contain audio, dynamic text, animations etc. Save them as PDFs before 
uploading... as all animations etc are going to be lost when uploading anyway.

There are a few additional changes you can make in:
/etc/ImageMagick-6/policy.xml which you would have edited when installing OM.

I remember having a similar issue a few years back when testing on a free tier 
on AWS before upgrading.

Hope this helps.

Denis

Re: [DISCUSSION] Calendar look'n'feel

[Denis Noctor]

Hi there Maxim. I took a look at both. To be honest, I still prefer the
look and feel of everything in OM 5.1.0 - it looks cleaner, less clunky,
consistency of fonts and shades etc. Can generate a few screenshots to make
comparisons if you'd like. Of course I'll be upgrading - but it's the look
and feel of OM 5.1.0 that's holding me back. :)

All the best.

Re: How to change email templates?

[Denis Noctor]

... sounds like a silly question to ask... but what’s the environment you’ve 
set OM on? Version of OM, platform and what installation approach you have used 
(for example Alvaro’s instructional PDFs etc).

Re: Clustering on AWS / Ubuntu 18.04 LTS

[Denis Noctor]

Hi there Maxim,

Thanks for getting back to me. I've already sent an email to Sebastian.

The clustering approach "looks" relatively straight forward as per the OM
site recommendations (and is something I am going to look at in more detail
over the weekend) but I am REALLY interested in trying to implement the
three different types of media streams: listen only, webcams, and screen
share over 3 KMS servers, as suggested in BBB (which as you may know uses
Kurento / WebRTC). Apologies for bringing up BBB but it appears to be the
only alternative that uses similar technologies that has addressed this
issue.

KMS limitations have been talked about over the last year or so - for
example... From what I recall, a standard OM / KMS setup can deal with
around 300 media server connections. Therefore a group of 5 people
sharing audio and video would in theory use 125 of these connections. (5
audio x 5 video x 5 people) but that will grow exponentially if you have 7
users (sharing audio and video... (7x7x7= 343). You might recall last year
that I reported on a physical test on one of the OM servers and I got about
9 users (audio and video) working in the same room before things got a
little shaky -  but let's be honest - having 9 or 10 users sharing audio
and video at the same time can be a little messy given the fact that their
video pods might unnecessarily take up a lot of "landscape" on the screen
also... but I would feel more relaxed knowing that if I have 7 - 9 students
in one room and a teacher teaching 7 - 9 students in another room that the
server isn't going to go down... irrespective of how good an AWS instance I
set up.

Last year, there was a time last year when I had 3 classes running
concurrently and unfortunately everything crashed. The one time only.
Memory usage spiked... but it all boiled down to KMS, it seems.

This led me to start looking into everything in more detail, for obvious
reasons. After all the time and effort I've spent in experimenting and
giving some casual feedback regarding OM, I think simply moving to a
commercially OM hosted environment would defeat the purpose of the learning
curve I have been on (apologies Sebastian, I mean no disrespect).

Anyway, if there is anyone out there that can give me any pointers on how
to spread KMS activity over 3 servers (over a single OM instance), I'd
appreciate it, paid or otherwise, let me know. This has been a great
experience and I'd like to continue my learning curve on this as much as
possible. I think this would open a gateway to a lot more conversation and
discussion a lot more ideas and a solid way forward with users and for
OM. Over the years I've seen users achieve what they need to achieve and
then disappear from the User List once they've accomplished (or not).
Anyway, I digress.

For reference the following links are the main ones I've come across that
have sparked this interest:

https://docs.bigbluebutton.org/admin/customize.html#run-three-parallel-kurento-media-servers
and
https://github.com/bigbluebutton/bigbluebutton/blob/master/bigbluebutton-config/bin/apply-lib.sh

Any suggestions from anybody would be appreciated.

I look forward to ANY suggestions on this matter. Please drop me a line
either via the forum or directly.

All the best.

Denis.

Clustering on AWS / Ubuntu 18.04 LTS

[Denis Noctor]

Hi there Maxim,

I hope this email finds you well.

I’ve been using OM over the last few years as mentioned in previous posts. 
Apologies for not commenting on previous updates and upgrades of recent.

I’ve been using OM 5.1.0 for some time now (on an AWS EC2 instance ) and is 
running well as expected but now I need to explore the issue of clustering due 
to KMS limitations, number of concurrent users etc per room (and instance) as 
has been previously documented in previous posts. I’ve been avoiding the issue 
as some of the classes I am running are scheduled at different times... but now 
I am faced with the issue of a handful of classes that run at the same time.

Is there anyone out there who has successfully got clustering working in an AWS 
environment (using Ubuntu 18.04)?

I would really appreciate it if anyone could give me some pointers. At present 
I have my AWS instance set up using Amazon’s Route 53, AWS certificate for 
https etc. If someone out there could give suggestions regarding setting up at 
least 2 instances using the same domain name, I’d be grateful and I could 
experiment from there.

I’ve included Ali in this email (hope you don’t mind... as I’ve been following 
your progress and contributions to this forum since this whole pandemic began).

All the best and thanks in advance. Denis.

Re: moodle plugin

[Denis Noctor]

Hi there Max,

Apologies for the silence on my side. I use moodle and have been doing so (on a 
different AWS server to that of the OM instance (5.1.0)). I haven’t integrated 
both of them to work with each other (yet), as my Moodle instance is still 
using PHP 5.6 and no SSL. More recent versions of Moodle require PHP 7 + and 
SSL cert to work. The reason I have been slow to upgrade my version of Moodle 
is because some of my MySQL code needs to be changed to MySQLi as many 
functions are deprecated and I also have my school database (on the same Moodle 
server) using old PHP pages which will require a rewrite. This is something I 
will work on over the weekend. Once I have both servers talking to each other, 
I will install the OM Moodle plugin as it is the last piece of the puzzle I 
need to work on. All the best.

Re: Mail sending error in openmeetings server

[Denis Noctor]

Just to be careful... rather than just using “sudo reboot”, make sure to 
shutdown all OM related activities in advanced... especially Maria Database 
(make a backup in advance) as it can sometimes corrupt the database. I’ve been 
there and it is not a nice experience.

openmeetings.properties

[Denis Noctor]

Hey there,

I’ve noticed over the last couple of weeks or so, some posts regarding users 
making reference to installing recent “builds” etc and having a few issues. Any 
chance they are following installation instructions regarding what is in the 
official OM online installation documents and not making the appropriate 
changes to the “openmeetings.properties” file as previously discussed in the 
forum but not necessarily in the immediate public domain. Just a thought. All 
the best, Denis.

Re: Users per room client browser scalability

[Denis Noctor]

Hi there guys. I was wondering if any further thought or considerations have 
been given to the whole numbers of user per room (vid cam / audio) and number 
of concurrent rooms per instance / server as it is seems to be one of the 
biggest issue / limitations regarding the platform. Any feedback would be much 
appreciated.

All the best,
Denis.

Will check. I know Chrome uses a lot of resources and after your message and 
some googling “chrome meeting uses lot of cpu” there are a lot of links 
over the last year reporting this... for a number of different browser based 
meeting platforms.

Re: Users per room client browser scalability

I didn’t as I was testing on the open meetings demo next website. Probably in 
the logs if they have not been cleared. If it is possible to view that info I 
could schedule and conduct another test.

Re: Users per room client browser scalability

[Denis Noctor]

Thanks for that Maxim.

I came across this...

https://docs.bigbluebutton.org/2.2/customize.html

(scroll down to "Run three parallel Kurento media servers").

This appears to suggest that 3 KMS (audio, video and screesharing)

All the best.

Re: Users per room client browser scalability

Hi there Maxim... I did a test with 8 computers and 2 tablets last night 
(spread across 2 WiFis)... please don’t delete the logs on the OM demo server 
(next)... I will come back to you all with some feedback and pics later 
tomorrow (if that’s okay)... however, for reference... I started the process in 
the public room #7...start time around 8.22pm (12th Nov) (México... 6 hrs 
behind) and end time 9.50pm... (if you want to check the logs)  the short 
version is that 8 users experienced relatively stable performance. Will give 
you a more detailed feedback once I deal with a personal issue. All the best, 
Denis.

Re: Users per room client browser scalability

[Denis Noctor]

Hi there everyone, this seems to be the “elephant in the room” discussion, 
while there has been a HUGE amount of development and progress in OM since 
March (thank you so much @Maxim) ... there is the whole issue of, for example, 
the number of users per room... which seems to be about 5-6 (and maybe even to 
7) when pushed to the limit... with both audio and video being broadcasted from 
all users... and, something else.. if there are simultaneous classes/sessions 
being held on the same server... will this restrict things even further? Is 
this an overall limitation to using a browser based approach... or should we be 
taking approach?

It was my intention to test out the OM “demo servers” over the last 2 weeks but 
will take today off and try to test 10 real device connections... with a 
combination of desktops, laptops, android tablets and maybe even the odd iPhone 
or two.

My million dollar question is... prior to WebRTC and Kurento... was it possible 
to have 5-10 users in a room with audio and video working seamlessly in 
previous versions (for example, the old “flash” setup (which will be redundant 
after Christmas... Chrome etc notifications) and if so, what has changed?

If there is anyone out there that has no problem with user numbers (using audio 
and vid)... exceeding a body of 7-10+, please let us know.

In the meantime, I’ll give you my feedback on my tests.

I really appreciate everything that has been done to date.

Thanks.

Re: Unusual Kurento Behaviour

[Denis Noctor]

Hi there Maxim. I did that. Cleared all logs in a variety of folders. All fine 
for now. Thanks for that. It’s amazing how much can build up over a few months. 
Maybe an additional “clean up logs” feature could be considered at admin level? 
I would also recommend that users clear their web browser cache on a regular 
basis also as things can get a little sluggish after a month or so of regular 
usage.

All the best.

Denis

Unusual Kurento Behaviour

[Denis Noctor]

Hi there guys,

Hope all is well. Just a quick observation regarding OM. It has been working 
relatively over the last few months (still using OM 5 M4), single server etc... 
but suddenly started spewing disconnection errors from KMS... I had a situation 
some time back when the Catalina.out file was growing to a huge extent... which 
seem to affect performance... and has since been addressed... but are any of 
you experiencing and irregularities whereby after a few weeks / months that the 
KMS server is constantly dropping connections? Any feedback would he 
appreciated. I have made no changes to the turnserver etc... everything was 
fine for weeks and then suddenly not. I have a feeling that it might be related 
to the huge Catalina.out Files that were created in the past but perhaps other 
huge files / logs are being generated elsewhere. If anyone can help me focus on 
additional files / logs etc that might be hogging the system, I’d be very 
grateful. But for now this seems to be an out of the blue scenario. Talk soon.

Users per room issue

[Denis Noctor]

Hi there everyone,

Apologies for bringing up the number of users per room issue... but has anyone 
else experienced an issue with 5+ users having to disconnect / reconnect issues 
per room?. The forum has been a little bit quiet regarding this issue despite a 
lot of concerns earlier. If you have come up with an overall solution, it would 
be great that you post it. I was using OM tonight and after 6 months... 
suddenly all users from all rooms were disconnected. Once I rebooted the server 
(Kurento related)... everything was okay... again).

Talk soon, Denis.

... follow up to last message, assuming Tomcat4 is installed... try reboot... 
then in the following order:

(Ubuntu... 18.04)

sudo /etc/init.d/coturn start
sudo /etc/init.d/mysql start
sudo /etc/init.d/kurento-media-server start
sudo /etc/init.d/tomcat4 start

Re: branding page header

[Denis Noctor]

I think you’re looking for this...

If you want to set up your logo in Openmeetings header you can do the following:

create your logo image as PNG 40px height
replace /opt/om/webapps/openmeetings/css/images/logo.png with your logo file
https://openmeetings.apache.org/WebappNamePath.html

Re: Download whiteboard file

[Denis Noctor]

Hi there Maxim. I think saving and downloading the whiteboard would be a great 
idea. For example, I’ve generated a few exercises in the past... where students 
needed to drag and drop the names of parts of a car which I had pre-prepared on 
a whiteboard. (I simply dragged a pdf file or image onto the whiteboard and 
then created a series of text boxes (or labels in this context)... and students 
were able to drag the corresponding labels to the relevant parts and so on. My 
teachers often asked me if I could share these lessons and as a result I would 
log into their room and drag the saved whiteboard file from my folder into 
their room folder in the folder tree (rather than copy and paste of course, as 
this option is not available)... and hey presto they could use it, saving 
preparation time... but if I wanted to reuse the file for myself again... I 
would need to go back to the other teachers folder... and drag it back into 
mine. It would be great to create more of these files and save them locally 
and upload them for future use. I am almost sure that I tested this perhaps 2 
years back... I will check my backups. Another example I had played around with 
was creating a chess board and pieces (very simple and basic but the same 
approach).

All the best.

Re: Connection to KMS dropping

Did you set up Turnserver? I haven’t used Linode but assume it might be behind 
a NAT firewall.

Search for “Turnserver” setup in the user group.

I am assuming the snapshot is recent... as a result please note that Maxim 
mentioned the following last week...

Re: docker container clustering experiments #1, Please respond

[Denis Noctor]

Actually... this is something that had crossed my mind recently. Previously, 
I’ve had on average 5 users per group... but on occasion if there more than 5 
users (in and around 7-10) some users... some would intentionally drop drop 
their cam... and sometimes mic... (I thought it might have been due to 
bandwidth issues on their side)... but I’ve got my own kids taking online 
classes via their schools... whereby there are a min of 20 attending a class 
and so on (different platforms etc.)

I have about a combination of 5 to 6 computers at home due to home office / 
covid restrictions etc. and am happy to log in to either the OM demo sites or 
others to try replicate this scenario. (and my own, of course).

Yep, I’ve been reading up on WebRTC and Kurento regarding connectivity 
limitations regarding audio and video... this has been covered a lot recently 
in previous posts in this forum... and from memory it is somewhere between 
200-300 connections... (per server? / instance?)

For example... if you have 5 users in a room (using audio and video) this will 
result in 5 (users) x 5 audio connections x 5 video connections... giving “125” 
connections... but if you have 7 users in a room receiving and experiencing 
audio and vid... that is 7x7x7= 343 connections... which obviously exceeds the 
connections as per previous posts.

I have had a scenario whereby 3 classes were held at the same time on the same 
AWS instance... and nobody has reported a problem (yet... or they unknowingly 
downplayed it due to internet bandwidth problems etc.)... but the max number of 
students per room has been 4-5

I am happy to test this more with others, if you are up for it and am watching 
this carefully.

I have a scheduled meeting with 10 participants next week and am now nervous... 
and curious to see how it works out.

Talk soon.

Denis

I suppose this all boils down to UDP being usually blocked by most private 
corporate networks. Only solution I can recommend is that UDP is unblocked on a 
public network.

General and Corporate User... (Off Topic... Sorry)

[Denis Noctor]

Hi there Maxim... and everyone out there,

I know this email might be considered a little off topic... but resonates an 
issue that may have been overlooked in the overall application of OM at a 
corporate level.

Let me try to explain. At present OM is browser based... thankfully Chrome and 
Firefox support WebRTC etc. I am aware of the Safari issues being discussed 
regarding audio and vid etc.

The majority of users I have are experiencing a relatively fluid experience 
regarding OM... however I have encountered 2 scenarios over the last few months 
that contradict each other... though it is not an OM issue... but maybe someone 
out there might be able to give some insight.

Company “A” (via it’s corporate WiFi network) was able to access a room... ... 
see room interactions (for example switching from whiteboard to whiteboard... 
typing onscreen etc) but could not share or receive audio/mic and video of 
other users. Clearly there were restrictions (firewall or others) on their 
side. However, when users used the public access network... everything was 
fine. Sweet. No problem now.

However, I have encountered a similar situation with Company “B”... and have 
asked them to use their “public” network... but they can’t experience incoming 
nor outgoing audio or cam.

Can you recommend a permissions checklist that they could follow to give them 
full access and functionality to OM?

One user from company “B” brought their computer home... logged in and they had 
no problem with audio/mic/cam so obviously there are restrictions on a 
corporate level.

Can anyone recommend a permissions checklist that company “B” needs to follow 
(grant access to)... without compromising their network or security?

Company “B” has used Zoom, Microsoft Teams without issue... but of course, 
these are downloaded apps (and not necessarily browser based).

@Maxim... I now this is going to cause you a headache... and I apologize in 
advance... but may open a few other discussions.

Any help, suggestions would be appreciated.

I know this is a huge request... but might shape future releases. 

All the best,

Denis.

Catalina.out

[Denis Noctor]

Hi there Maxim,

I hope this email finds you well. Just a quick observation. Approximately
once per month, I've noticed that video and camera drop quite regularly at
the start of a session. I noticed that the Catalina.out file grows to be
quite large more than 1 gig. On previous occasions the file has grown
to larger sizes (2-3 gigs), depending on usage. However, if I shutdown OM,
delete the catalina.out file, restart all the relevant services whereby a
new catalina.out file is created... things go back to normal... and
normally continue to do so... until the file grows again over the next
month or so. Overall disk usage is approx 50% and is easily scalable if
required via AWS.

On a separate note, if any of my students experience any sluggish
behaviour, I usually ask them to empty their cache once per month (they
usually use Chrome or Firefox) and things seem to be much better also.

As a general rule of cleaning up and housekeeping, can you recommend any
other files, folders, temp directories that may be required to be cleaned
on a regular basis?

I have still to reinstall OM 5.0.1 so at present am using *OM 5 M4*, *Ubuntu
18.04* on AWS.

All the best,

Denis.

You just beat me to my answer. Based of the graphics and the minimize tab

Re: odd case or normal?

[Denis Noctor]

Thanks again Maxim. Will check this out in the morning. Apologies for causing 
upset... but curious also to know If other users expressed similar concerns on 
“upgrade” rather than a “fresh install”. Talk soon. All the best, Denis.

Re: odd case or normal?

[Denis Noctor]

Hi there. I needed to make a clean install (OM 5 M4) before recording all 
changes and so on... but agree this might be a java process issue. Will set up 
another clean AWS instance setup with 5.0.1 most recent snapshot tomorrow, 
compare with current installation and report back tomorrow. Apart from 
Tomcat4... the only major installations changes I have noticed (not including 
improved UI and Android / IOS) improvements /  is the MySQL-connector-Java 
8.0.19 to 8.0.20 and “chown -R nobody:nogroup /opt/open501”... I haven’t used 
“nogroup” in previous installations / upgrades. Hope this makes sense. None of 
my current users use Mac / Safari etc. Talk soon. All the best, Denis.

Re: odd case or normal?

[Denis Noctor]

I experienced this after upgrading to a 5.0.1 snapshot and was about to follow 
up a response to Maxim. Not at a computer at the moment but I experienced 
exactly the same. I  am using Ubuntu 18.04 on AWS with 8 gigs ram. When SSH’ing 
to my server (with only one user logged in (me) I noticed RAM usage was 98%... 

I downgraded to OM 5 M4 and everything is fine again (but lack the advantages 
of the snapshot upgrade)... RAM usage dropped a lot also... a lot!

Will take some time to compare tomcat3 and tomcat4 on startup, folder 
permissions and differences between OM 5 M4 and recent snapshot.

All the best,

Denis.

Re: Upgrading from OM 5 M4

[Denis Noctor]

Hi there Maxim... sorry to have to annoy you about this again. I decided to do 
a reinstall of the OM 5.0.1 , new database and so on. When I log in with 2 
users, 2 machines etc... sometimes both users can see and hear each other... 
but most times not...sometimes not... unless they disconnect their cams and 
audio and reconnect. This sometimes takes a few attempts. Once a stable 
connection is established... everything is fine.

I used to have things working great on OM 5 M4... and I don’t seem to have done 
any major changes.

I have thought about doing a purge and reinstall of Kurento... any suggestions 
how to do so.

Using Ubuntu 18.04.

Thanks in advance.

Upgrading from OM 5 M4

[Denis Noctor]

Hi there Maxim,

Are there a lot of differences between OM 5 M4 and OM 5.0.1 and current 
snapshots (regarding general architecture)?

As I mentioned in previous emails (regarding the mute issue). I did such an 
upgrade but am starting to see a few glitches that I cannot emulate on the demo 
servers. Users can see and hear some users but not all and vice versa... and 
seems a little random.   I am aware of the whole turnserver side of things and 
I had this working great on OM 5 M4... and I purged and reinstalled Imagemagick 
to address the file conversion problem... but I am wondering if simply 
upgrading from M4 to OM 5.0.1 is not the way forward. For example, I reimported 
my a database recently from OM 5 M4 and that’s when things started to go a 
little odd. I assume that the DB structure is different in 5.0.1 +?

As strange as it sounds... it appears that users that were imported from the 
old DB don’t “ appear “ to have “major” (the occasional refresh is required) 
connectivity issues regarding cams and mics... but most of the new users that 
were added do.  I think I will reinstall afresh... and repopulate the DB 
manually and see if that makes a difference.

Before I do I was wondering if anyone was in the same boat etc.

All the best,

Denis

Re: Converting documents after upgrade

Once again Maxim... you have proved to be a total star.

sudo -u nobody /usr/lib/libreoffice/program/soffice --version
gave me a critical permissions error which unfortunately did not note
down... however, I reinstalled as suggested.
(I corrected 2 typos just in case this is revisited).

Once again. Thank you.

Re: Converting documents after upgrade

[Denis Noctor]

I made my own... which I think might be the root of the problem changed 
folder name to open510... but made relevant changes in tomcat4... 

Seems to be a permissions issue... will review and check...

Converting documents after upgrade

[Denis Noctor]

Hi there guys,

Having recently upgraded to the OM 5.1.O snapshot, I realize I can only
upload pdfs and jpgs - no other file conversion appears to work... (all
other functionality etc seems fine).

Everything works fine on https://om.alteametasoft.com:8443/next/ so the
problem is clearly on my side.

Any suggestions before considering a clean reinstall?

Thanks

Denis

Re: Mute all users... and some more

[Denis Noctor]

Of course Maxim. When you click the check button and then click ok, the pop up 
message will disappear (as intended)... it will work as expected but for one 
attempt only. When you double click another user’s video pod to speak (with the 
intention of muting others)... the microphone graphic is displayed but nothing 
happens.

As a result, a user needs to delete their cache in order to revert back to the 
pop up message approach...  in order to be able to mute all users except the 
designated speaker etc.

Hope this helps.

All the best.

Denis

Re: Mute all users... and some more

[Denis Noctor]

Hi there Maxim,

Apologies for the previous long email. I had previously tried your
suggestions - the results being the same on the OM demo site below:

I tested the following mute functionality on the
*https://om.alteametasoft.com/openmeetings
<https://om.alteametasoft.com/openmeetings>* demo site also and noticed the
following (with 3 users):

*SHIFT + F7* (works as expected as a quick on / off toggle for individual
users)

*SHIFT + F12* mutes *all users (including moderator)*... however, moderator
and all participants will have to click individually on the "speaker
/audio" of all participants if they want to hear each other again.
Perhaps it would be more useful to mute everybody... except the
moderator... whereby everyone can at least hear the moderator.

Finally (the function I am really eager to use), clicking on a users video
pod (or avatar when they have their camera deactivated) in order "mute
microphones of others"... will result in the popup message "Do you really
want to mute all users except this one?" ... but does not do anything. As I
can't test this any further, I can only assume that would this mute the
moderator also and if so would it best to "mute all others except this one
and the moderator".

I tested this using the latest versions of Chrome and Firefox. When using
Firefox the current hotkeys open the Firefox web debugging tools also.The
room type I was using was "conference" (
https://om.alteametasoft.com/openmeetings/#room/98659).

All the best,

Denis

Mute all users... and some more

[Denis Noctor]

Hi there guys, I am using the previous version of OM prior to the current 
upgrade... which will probably solve my issue... but just in case...

I am in a rare situation where some of my users are in the same office 
environment... and as a result there is the obvious sound / audio feedback. 
They are using multiple devices so my natural recommendation would be to “mute 
all users”... except me... when I want to speak... especially for longer 
periods of time... and then when I want user “x” to participate I would ask 
user “x”  to “unmute” and talk... and when he/she is finished  to “mute” 
unfortunately when I “mute all users” it also mutes me (the moderator). My 
work-around is to inform the participants in advance that I will “mute 
everybody” to eliminate echo and feedback and then ask them to individually 
“unmute” me... and then them etc.

Again this is a rare scenario that might have slipped the net... the 
alternative would be to have external speakers for the audio (muting 
everyone... except the moderator) and using a for example... a conference 
microphone... to pick up on what each individual is saying... whereby on 
designated user in the group activates audio / mic etc but then in this 
situation it is quite difficult to know who is speaking... as that microphone 
is connected to one user’s computer.

Any suggestions, work-arounds on this?

I know the ideal situation would be for the participants to find different 
isolated positions in the building to work from... but I assure you... in this 
situation it is not physically possible... even though I am told they are 
taking Covid seriously. And honestly, I’ve exhausted all of these measures with 
the company. However, some of the workers do not have access to computers at 
home and as a result will share an office environment with a projector and so 
on. Please do not let this posting turn into something other than a tech and 
application usage recommendation / suggestion... because I’m honestly, I am 
tired, emotionally and mentally drained.

Finally @Maxim and @Sebastian... on a totally different note... I had a game of 
Chess on OM with my son recently (without screen sharing) ... which was fun... 
a little bit Mickey Mouse... but it worked... which makes me think we should 
open an “applications” usage group for OM... showing its practicality rather 
than anything else... whereby users can upload/download workable ideas, 
classes, ideas  ... etc from the platform As an English teacher and 
exhausted business owner... hopefully this message will inspire...

Again, and sorry for the repetition, this platform can be used, with the proper 
guidance to deliver a professional class.

All the best,

Denis.

Re: proplems with new release, room configs are different ...

[Denis Noctor]

Well spotted Maxim. When I did a test I didn’t realize when doing so the 2 user 
accounts I was testing both had moderator permissions. Silly me.

I’m sure @kaffeesurrogat will be happy to hear that it was not only him.

All the best.

Re: Direct link for entering the room with room name (not ID)

[Denis Noctor]

Would assume instead of https://domain name.com/openmeetings/#room/14 you 
can personalize it “if required” for example https://domain 
name.com/openmeetings/danielsclass (or something similar)
... discouraging users from poking around with other room id numbers...

I haven’t checked... but assume these changes can be made in 
administration—>conference rooms.

All the best.

Re: proplems with new release, room configs are different ...

[Denis Noctor]

If you take a look at this...
https://openmeetings.apache.org/

Near the bottom of the page you will notice one of the changes / 
improvements... “Direct link for entering the room with room name (not ID)”

As a result... maybe... there are some field changes (additions) to the 
database.

You previously mentioned: 2 rooms, 2 different servers, 2 different versions of 
OM. I would keep everything the same... same version of OM.

I’ve tried to reproduce this on my set up... using one server, 2 users logged 
into the same room (one using updated version of Chrome and the other using 
updated Firefox),  one install of OM on server and everything works fine.

Re: proplems with new release, room configs are different ...

[Denis Noctor]

So let me get try to get my head around this... because I didn’t notice you 
mention this before... Are you trying to set up a “clustering environment” 
using 2 different versions of OM?

Re: proplems with new release

[Denis Noctor]

@kaffeesurrogat,

First of all can you confirm that you can see and hear at least 2 users in a 
room as it is a little unclear... and if you’ve read my previous email.

I won’t be able to respond immediately as I am on the the other side of the 
planet and am heading off to bed... (1.38am)... but I am curious to see if you 
have been able to reproduce this scenario more than once... as it is not very 
clear from your posts.

The situation you described might be exceptionally rare... as I can’t see the 
reason for a moderator to leave a room when others are in it... and as a result 
this scenario might be an oversight... but a very small one... taking meeting 
protocol into consideration. But I’ve recommended an alternative.

Hope this helps somewhat.

Again, it is important to stress that it would be useful to identify server 
specs, browser versions and so on.

All the best, Denis.

Re: proplems with new release

[Denis Noctor]

@kaffeesurogat

Hi there Kaffeesurogat,

Generally speaking what you posted seems fine. As @Alvaro has stated also.

I wrote to you regarding in-company restrictions before and from what I gather, 
the previous problems you had were fixed, is that right?

If a room is set up whereby “wait for a moderator” is configured... that is all 
well and good... but but not necessarily decorum to leave the room leaving 
participants to be automatically disconnected.

I had a situation whereby I needed to exit a room and told my students to work 
on an exercise and I would be back shortly. My phone was flooded with texts 
saying they were unable to see anything until I returned. I changed the room 
configuration whereby anyone could enter the room before me... but they had to 
refresh the browser... alternatively delegate another moderator. Yep, there 
were a stream of errors until they did so.

What I’d like to know is has everything been sorted out since my last email.

If yes, I would recommend that rather than a moderator leave a room when other 
people are in it, simply inform users that you are disappearing for a moment 
and turn off the cam and mic. If needed, give the other users “presenter 
privileges” in your absence.

The error that you described revolves around the Kurento Media Server issues 
that you previously described. Can you confirm you are able to get a 2 user 
setting whereby both users are able to see and hear each other in the “work” 
scenario you previously described?

All the best. Denis.

Screen share with sound?

[Denis Noctor]

Hi there everyone,

While I have been avoiding screen sharing for quite some time (bandwidth 
concerns etc)... I decided to look into it a little more today. For example if 
I need to use audio and video, I usually upload everything... and that’s fine. 
But sometimes I would prefer to share my web browser and simple play a YouTube 
audio / vid clip etc. , saving me a lot of time on preparation and uploads. Is 
this possible under the current OM setup? Maybe I’ve overlooked something.

Thanks in advance.

Re: DEMO SERVER Media Server Connection fails too

[Denis Noctor]

@kaffeesurrogat 

Port 443

(*Port 443*. Description: This *port* is *used for* secure web browser
communication. Data transferred across such connections are highly
resistant to eavesdropping and interception.)

Note "secure" in the above description. For example WebRTC will not work
without https via Chrome.

You can easily check what is being used to access your camera and mic via
Chrome...

For example - in my case, if I put https://mydomain.com  it is
automatically redirected to https://mydomain.com/openmeetings

Once I am logged in and do the camera / mic test on the dashboard page  -
which opens up the test page in another tab... and "save" my
configuration... which allows camera and mic permissions... I can then
check the Chrome browser settings... simply open up "Settings" in
Chrome...click on "Privacy and security" on the left side of the settings
page that opens up... scroll to "Site Settings"... click on it... and
scroll down to "Permissions"... you will see there is an option to check
both camera and microphone... when you click on either of these options you
will see a list of website addresses that have been given permission to
access your camera and mic... however, the urls will also identify the
port in my case it shows *https://mydomain.com:443
<https://mydomain.com:443>*

You mentioned that access to your OM setup works at home but not at work...
so there is clearly an access restriction... I would start off by simply
asking your IT guys to remove restrictions to whatever the full URL address
with port number shows up in the Chrome settings as described above. It is
not uncommon companies restrict access to sites for example prohibiting
social media access during work hours etc.

As I am working on very limited information... when you mention everything
works at home... I am assuming you can conduct a basic test by using 2
computers, with 2 OM accounts that have access to the same room whereby you
can see and hear each user?

One more point... assuming everything is set up correctly with OM... the
fact that you mentioned that Big Blue Button (which also uses WebRTC and
Kurento... and Turnserver config... if required) is not working also in the
work environment (and assuming that has also been set up correctly)... then
more than likely they share the same problem - simply down to user access
restrictions.

While this is not the most techie of responses I have shared... I had a
situation some time back where the majority of my users were operating from
home... but 1 user was operating from work and couldn't view or hear
other users in a room (the other users were able to see and hear each other
but not the person working from home. In this scenario it was easy to
identify the problem was on his side. As a result, I would start by
eliminating this problematic scenario before taking everything apart!

And finally, when you do get everything working... you will realize that OM
has come a long way in the last year and knocks the socks of BBB! A huge
"thank you" @Maxim!

Let me know if you get this resolved. If it turns out that there were
restrictions... I would write a "fresh thread" detailing the solution so
other users that experience the same problem can find it.

All the best.

Denis

Re: DEMO SERVER Media Server Connection fails too

[Denis Noctor]

Correct... but don't forget port 443. For example, the vast majority of my
users are working from home due to the whole covid situation and as a
result the average user may not have any strict restrictions on their
router etc... however, some companies may have restrictive access in the
workplace environment... for example not letting employees have access to
Facebook etc. Of all the students who have been using OM, (with the
exception of asking those to update their version of Chrome and Firefox
browser... and not taking into consideration the most recent Safari / IOS
posts) - only one user (accessing OM from work... using the same laptop he
uses at work and home(no problems at home) was experiencing the problem you
described - as a result, I had to assume there were restrictions on his
side. It turned out that there were restrictions on his side and once they
were lifted, he has been able to use OM with no problem.

Hope this helps.

Where are OM backups stored?

[Denis Noctor]

Hi there Maxim,

I hope this email finds you well. I made a huge mistake of doing a OM
system backup via the user interface (which included uploaded files (which
total more than 8 gigs). Unfortunately I did not realize that this resulted
in my Amazon Instance Disk Volume becoming 100% full and the backup was
interrupted (no space to complete the backup) - also resulting in me to no
longer being able to SSH the instance... or restart it. I have since been
able to make a copy of the volume via Amazon and mounted it to a new
instance volume to see if I can delete backup files that are taking up
unnecessary space... and then remount the volume to the original instance.
Any idea where this (these) backup file(s) are temporarily located before
being downloaded to desktop so I can delete them. A faster approach would
probably be to do a fresh install... but that will result in me losing my
Maria DB also.

Using OM 5 M3 / Ubuntu 18.04 LTS / AWS EC2

Any feedback would be much appreciated.

All the best,

Denis

Re: Problem using Kurento Media server

[Denis Noctor]

Try updating Chrome and Firefox to latest version. Strange as it may seem, I’ve 
found Firefox to be more stable when using a HP laptop that has a truevision 
webcam but my Dell laptop works better with Chrome. Unfortunately, I can’t 
offer an explanation as to why at this stage. Saying that, I am still using OM  
5 M3 and will report any other differences when I upgrade.

Re: AWS lightsail

[Denis Noctor]

Hi there guys. I thought I’d throw in my 2 cents in on this. I am using an AWS 
EC2 instance. From my understand all instances are behind NAT which as a result 
requires a Turnserver. In one of my previous emails I described the approach I 
took (check the OM user forum). I am using my phone to write this email... so 
as you can imagine searching, copying and pasting a link to the actual message 
would be a little cumbersome... but the subject of the email is “Suggested AWS 
EC2 setup - OM 5.0.0 M3 / Ubuntu 18.04”. For the moment the instance I am 
running is as follows:

LAMP image (Linux, Apache, MySQL, and PHP setup). My AWS Setup is as follows:
Instance type: t3a.large (8 gigs Ram , 2 vCPUS), I was previously using a 
t3a.medium (4 gigs Ram , 2 vCPUS)… which seemed to run okay… but needed to 
elimate any doubts I had by cranking up the RAM. Some of you may decide to go 
for lower or higher instances depending on your budget and desired performance 
levels etc.

For reference this instance is costing me about $50 dollars. But would be a lot 
cheaper if I didn’t use AWS’s Route 52 (domain to designated IP address).

I had run everything on a free tier a couple of years back but document 
conversion was slow and often crashed.

I have been and a couple of my guys have been running simultaneous classes over 
the last few weeks and generally speaking everything has been fine. A few 
browser issues as mentioned in a previous email... but it is important to state 
I am using OM M3, which I will update and configure at the weekend. Some 
classes we 1hr 30 mins, some 5 hours on a Saturday. Average meeting 5 - 8 
people. 

My short to long term plan would be to set up a “clustering” model which was 
discussed in the forum a few weeks back, maybe longer... having the database in 
one AWS “bucket” and several other instances.

I would be happy to help out in any way regarding load testing. I’ll be honest 
I’d be hard fetched to ask my students to participate... but I have about 5 
computers at home since I’ve been in quarantine and happy to participate where 
as Maxim stated... 4 can participate on a “silent” basis. Given the amount of 
people in the group... I’d say a “call for action” email to all the users will 
be received well and more people might be able to help with a load test as 
Sebastian mentioned.

Either way, I’m here to help in any way.

I’ve been out of the loop for the last few weeks but, again, if there is any 
way I can continue to help in any way I will.

All the best, Denis.

I couldn’t agree more with Maxim. I think there is more emphasis required on 
functionality rather than cosmetics at this stage. I’ve got a list as long as 
my arm at this stage and consciously decided not to bring them into 
conversation for now, so as not to distract everyone from the main objective as 
to having such a platform up and running. If it meets the basic requirements, 
of which I have not tested everything (for example recording and so on... which 
my students would feel a little uncomfortable about anyway)... but yes, I agree 
there are tweaks and issues that can be addressed on a user by user basis... 
some of which are great but maybe we can address this in a different 
forum... “Tweaks and Issues” ... or even “themes issues” etc... maybe... as an 
example. Either way... as limited as my experience is... I’ve grown an 
affiliation to this group... and the resources are huge. Google or use of  the 
search query in the forums will offer some wonderful guidance and I will 
personally do my best to help with certain queries... we all know that Maxim 
answers as many queries as possible but how many of you know how many 
Maxims are out there? Hope this makes sense, I don’t intend to sound 
arrogant... but if you are looking for a national health service equivalent... 
Maxim is... and has been... your frontline. Goodnight.

Suggested AWS EC2 setup - OM 5.0.0 M3 / Ubuntu 18.04

[Denis Noctor]

Hi there everyone,

I thought this email might be of some interest to those setting up OM on an
AWS EC2 instance using Ubuntu 18.04.4 LTS (GNU/Linux 4.15.0-1063-aws
x86_64). There are lots of tutorials online regarding how to setup an AWS
EC2 instance, so there is no need for me to talk about that. I am assuming
you have this up and running.

However there are lots of *free* AMIs (Amazon Machine Images) in AWS that
can be automatically installed which will install a LAMP image (Linux,
Apache, MySQL, and PHP setup) and the one I used was:
“ubuntu/images/hvm-ssd/ubuntu-bionic-18.04-amd64-server-20190212.1
(ami-0a313d6098716f372)”

 I will have to update my PHP version at some stage though.

My AWS Setup is as follows:
Instance type: t3a.large (8 gigs Ram , 2 vCPUS), I was previously using a
t3a.medium (4 gigs Ram , 2 vCPUS)… which seemed to run okay… but needed to
elimate any doubts I had by cranking up the RAM. Some of you may decide to
go for lower or higher instances depending on your budget and desired
performance levels etc.

It is also important to note that I am using an Elastic IP address, which
basically means the IP address of my domain will never change and as a
result my registered domain name, for example “ABC.COM” will be directed to
this IP address…. Even if I “stop” my server to save money.

I am also using a “AWS load balancer” which also entitles me to a free
certificate which automatically renews every 12 months when set up (again
lots of info on the internet about this)  - which is an IMPORTANT POINT as
I am not using LetsEncrypt… AND AS A RESULT DEVIATE FROM ALVARO’S WONDERFUL
INSTRUCTIONS.

Let’s begin…

If you are setting up a clean install… simply follow Alvaro’s instructions
via this link:
https://cwiki.apache.org/confluence/display/OPENMEETINGS/Tutorials+for+installing+OpenMeetings+and+Tools?preview=/27838216/140774282/Installation%20OpenMeetings%205.0.0-M3%20on%20Ubuntu%2018.04%20LTS.pdf

Again, this is for OM 5.0.0-M3. If you wish to update to further snapshots
please refer to the official website, forums and links.

Please note the current version of Alvaro’s PDF… at the time of writing it
was v6.

(Assuming you have already got an AWS certificate:  you can setup your
domain as https… redirecting all http to https…. I recommend you do this
before).

NEXT STAGE – SETTING UP THE TURN SERVER.

I had originally used a free TURN server service… using
https://numb.viagenie.ca/  whereby you can setup an account… and had tested
it… and it seemed to be okay…. But I don’t like to be dependent on a 3rd
party… especially when it comes to testing… I decided to set up my own… on
the same AWS EC2 instance.

Please refer to Alvaro’s additional setup regarding “Installation SSL
certificates and Coturn for OpenMeetings 5.0.0-M3”… via the following link
--- BUT PLEASE NOTE WE ARE NOT GOING TO FOLLOW ALL THE INSTRUCTIONS TO THE
LETTER:

https://cwiki.apache.org/confluence/display/OPENMEETINGS/Tutorials+for+installing+OpenMeetings+and+Tools?preview=/27838216/148644256/Installation%20SSL%20certificates%20and%20Coturn%20for%20OpenMeetings%205.0.0-M3.pdf

As I am using an AWS certificate, I am going to bypass / ignore all
references to “letsencrypt”… and here is the why… with AWS certificates you
have no control over them… you cannot download the certificate and store it
on your server… you cannot download files, like in “letsencrypt” in
Alvaro’s example … you have no access to “fullchain.pem”, “privkey.pem”.
These files are stored elsewhere in AWS... but are automatically detected
and enforced by AWS… (you could use Letsencrypt as an alternative
certificate source but this is not what this email is all about… and I
haven’t had the need to test it.)

SKIP PARTS 1,2,3 AND 4 of Alvaro’s tutorial in “Installation SSL
certificates and Coturn for OpenMeetings 5.0.0-M3”… and go straight to part
(5)… do as instructed.

In part (6) of the tutorial I decided not to change the user name in the
following as I had already set up the user name in the original OM 5.0.0 M3
instructions (“nobody”):
so instead of making the change:
*user=kurento:a_new_password*

I changed it to user=nobody:a_new_password

making all the other changes in part (6) as stated.

I *DID NOT *implement changes in part (7)  regarding
 DAEMON_USER="kurento"… I left it as "nobody"



However, I did make changes to the
/opt/open503/webapps/openmeetings/WEB-INF/classes/applicationContext.xml as
follows:




 Remember we are still in part (7)… after saving the changes to the above
(applicationContext.xml), I *DID NOT* make changes to

sudo chown -R kurento /opt/open503

I decided to keep it the same as per the original 5.0.0 M3 setup… (keeping
it as “nobody”)

I *DID NOT* modify:

sudo nano /etc/init.d/tomcat3

(i.e. changing “nobody” to “kurento”)

*AND FINALLY I MADE THE FOLLOWING CHANGE* – NOT IN THE STEPS:
/etc/kurento/modules/kurento/WebRtcEndpoint.conf.ini

turnURL=* nobody*:*PASSWORD* @* PUBLIC IP ADDRESS OF AWS SERVER*:3478

Reboot 

Re: Related to Mice and Audio issue in openmeetings

[Denis Noctor]

Hi there Maxim,

Thank you so much for the offer of going through the log files. However, after 
seeing the volume of emails you’ve been answering... and continue to do so, I 
didn’t think it was fair to distract you further with my problem and as a 
result decided to go through everything again and I have since worked it out 
(after one or two surprises also). I have everything now working on an AWS EC2 
instance, using my own TURN server setup.

I am going to write a separate email regarding how I set everything up on 
AWS as the setup is slightly different and hope this will be of some help 
to the group.

I just want to take the opportunity now to say a “Big Thank You!” And extend a 
virtual hug. I am not a real techie and as a result am amazed at the level of 
patience and support that is given in this group ... and want to say thank you 
to all those who have positively contributed to this forum also.

I will continue to look at the snapshots and give my input and feedback no 
matter how small.

Thanks again.

Denis
