Re: Invalid Hash via SOAP API call

[Maxim Solodovnik]

Well,

just tested hashes
This error is only observed in case multiple tabs are opened in the same
browser

Is this issue reproducible for you if there is only one user in the room?

Can you test this behavior with latest M4
(new version of Moodle plugin will be required)

[HELP NEEDED] 5.0.0 release

[Maxim Solodovnik]

Hello All,

I would like to release 5.0.0-M4 in nearest couple of weeks

Current blockers are:
1) https://issues.apache.org/jira/browse/OPENMEETINGS-2192
2) invitation/secure hashes need to be tested in clustered mode
3) "Files messed up during backup restore" (steps still required)
4*) Camera/Microphone are disconnected sometimes

Additionally I would like to implement this one
https://issues.apache.org/jira/browse/OPENMEETINGS-2167

And check some other issues (like OM at Safari)

I would like to get some help with testing latest SNAPSHOT:
https://builds.apache.org/view/M-R/view/OpenMeetings/job/openmeetings/
It is also installed at demo-next
https://om.alteametasoft.com:8443/next

Please test this version and report back any issues found

Thanks in advance

Re: Related to Mice and Audio issue in openmeetings

[Maxim Solodovnik]

Can you share your openmeetings.log (can be shared privately)
Better if it will be log for one session (with exact times of camera drops)

And couple of words about your client environment
OS/Browser

Is the issue browser dependent?

The only report like this so far was from user at Windows Terminal server
...

Re: video problems

[Maxim Solodovnik]

TURN is required if your users are using restricted networks
Or even not very restricted like wifi router at home

Re: Related to Mice and Audio issue in openmeetings

[Denis Noctor]

Hi there Maxim,

First of all, thanks for all your efforts to date. I have noticed via the
forum you have been fighting fires answering lots of emails and queries and
I salute you.

I decided it best to take a few days before answering you email after
upgrading everything to *OM 5 M3* (as per Alvaro’s instructions, which are
great).
Version5.0.0-M3
Revision b739f87
Build date 2019-12-11T11:42:09Z
Connect direct
Using Chrome browser (as are my students) Version 80.0.3987.149 (Official
Build) (64-bit)

AWS E2 Instance
Ubuntu 18.04.4 LTS(FULL SPECS AND PORTS OPEN AT THE BOTTOM OF EMAIL
https:// with AWS Certificate

I installed everything as per the instructions and setup up a “*Turn server*”
account with *NUMB*  (*http://numb.viagenie.ca/ *)
as recommended by as per Tajuddin Bennur’s

https://mail-archives.apache.org/mod_mbox/openmeetings-user/201905.mbox/browser

and made the following changes (*ONLY*) as per the recommendations in:
/etc/kurento/modules/kurento/WebRtcEndpoint.conf.ini

uncommenting and adding:


*turnURL=USERNAME:PASSWORD@158.69.221.198:3478
 *In
/opt/openmeetings/webapps/openmeetings/WEB-INF/classes/applicationContext.xml

The only changes I made were similar to those above (though I tested
everything before adding these changes are the following – but honestly, I
haven’t really noticed any difference:

http://158.69.221.198:3478>"*

*p:turnUser="USERNAME"*

*p:turnSecret="PASSWORD"*

p:turnMode="rest"

p:turnTtl="60"

p:objCheckTimeout="200"

/>




The end result is: Whiteboard for my uses is working beautifully,
conversion process is working beautifully, drag and drop of audio and video
is working beautifully… though I tried to upload a 59 M file and everything
seemed to hang for a while so I cancelled the upload… but appeared in my
online files later on… probably more ram and CPU speed will deal with
this.. no major problem as I re-uploaded a smaller vid file and it did the
job.

In all everything is working well except for the following:

When enter a room, I can see and talk to a student ( and vice versa) very
well. Audio quality is good and cam settings are as expected. This is
something I couldn’t do in the past without the recommended Turn Server
settings as mentioned about.

*PROBLEM:*
When I enter a conference room( first), and then when 2 students enter the
room…  after some time my cam box disappears from my screen. I am still in
the room… I can still hear and see everyone else interacting with each
other – but they can’t see or hear me. When I click on the cam and camera
icon everything continues as normal until it happens again. Worth noting –
I am the moderator.

However, if I don’t turn on my camera and microphone again… after some time
the same thing happens to the first user that entered the room after me…
and so on.

Apart from that everything is working really well. I remember some time
back that a similar problem occurred with a user in the past but I can find
anything in the user forums.

Again important to note that I am using a TURN SERVER setup as mentioned
above…. I have NOT implemented COTURN as I am under the impression TURN
overrides COTURN.(?).

Any suggestions / help as to what might be causing this?

All the best,

Denis

Take a look at the kern.log, if your firewall drops sth.
I guess sth. like this would help:
iptables -A INPUT -p udp -m udp  --dport 1:65535 -j ACCEPTiptables -A 
OUTPUT -p udp -m udp  --sport 1:65535 -j ACCEPTiptables -A INPUT -p udp -m

Re: video problems

[stefanx]

Our Server has an official ip adress (no NAT), I've read something about the 
turn server in this forum,
but it isn't really understandable to me. That means the installation manual 
for Ubuntu 18.04 in
https://cwiki.apache.org/confluence/display/OPENMEETINGS/Tutorials+for+installing+OpenMeetings+and+Tools
isn't really complete ?

Everything seems to work, with one exception: In a room all users can only see 
there own video, but they
cannot get a video connection to the other users (audio works). I've disabled 
the firewall, but with no effect.

Any ideas ?

Best regards

Stefan

Unexpected exception while checking hashesjava.lang.NullPointerException: null

Hi, second message in a row. Again, OM 4.0.10, openjdk 11, ubuntu 18.04.
I'm finding this in the output, I really don't know how to reproduce it, or
what effect has in the final user's experience, but it's an exception, so
it may cause a wrong behavior:

Unable to send message to NULL scope

[Rodolfo Gonzalez]

Hi,

with a 4.0.10 installation, java openjdk 11, ubuntu 18.04, I'm finding many
ot these messages in the output:

DEBUG 03-26 08:57:08.055 o.a.o.c.r.ScopeApplicationAdapter:800

OM is integrated to a web app using SOAP API.

I found a thread about the same message, but I can not find a resolution.

Thanks.

Re: Invalid Hash via SOAP API call

[Maxim Solodovnik]

According to above access log
This URL
/openmeetings/hash?&secure=9c271470-cfaa-4e95-9d64-9210b9e4a7cc&language=1
has been queried 2 times
First one was
/openmeetings/hash?&secure=9c271470-cfaa-4e95-9d64-9210b9e4a7cc&language=1
Second
/openmeetings/hash;jsessionid=CE0DC1A368404F8AFDCE934313E81C96?secure=9c271470-cfaa-4e95-9d64-9210b9e4a7cc&language=1

Since secureHash is one-time hash here might be the issue
It is not clear why session was invalidated .
I'll try to perform more test tonight/tomorrow

Re: newbie problem, seeing : The value of 'from' is not a valid LocalDateTime.

[Maxim Solodovnik]

FF works for me

What version of FF do you have? What is your OS?

haven't looked yet, but the PC I'm using to connect doesn't have a 
microphone or a camera connected.





Anything in browser console?


Nothing useful that I can see

Doesn't do it in Edge, Edge works ok. Once the invite is sent in Edge, 
Firefox can open the room and collaborate in the whiteboard, so it's not 
an easy one to fix, workaround is don't use FF, I guess :(
