No, as I can follow the log (tail -f ./logfile) and and I see exactly my requests there.

I downloaded the file from 

sudo wget https://downloads.apache.org/openmeetings/5.0.1/bin/apache-openmeetings-5.0.1.tar.gz 

as described in Alvaro's tutorial. And the file downloaded that still resides in the folder says 


/opt # dir
apache-openmeetings-5.0.1.tar.gz 

Is exactly that. I also can rule out the possibility that some older version resided on that server because it is a fresh new server. 

Did someone hack into that file?

1. First thing that annoyed me was the fact that I cannot restore the USERS and FILES tab once removed the to the right. 

this make no sense, please provide steps to reproduce 

2. The FILES tab shows folders with moving errors only. I suppose this signals some failure. Upload is impossible too. Though I can see the file in the folder, an exclamation mark signals some error, and I cannot drag it on to the whiteboard. 

same here 
what is "moving errors? since upload is impossible what in the logs/browser console? 
I'm afraid no one can help you with this level of details :( 

I suppose the reason is some problem with permissions. I set the whole OM folder to 
chown -R nobody:nogroup ./OM-Folder 
But nothing changed.

Call for Logo

[Thomas Scholzen]

https://openmeetings.apache.org/CallForLogo.html 

Dear All, 


I would like to get the discussion about the logos going a bit. In
general, I think the logos should be kept as simple as possible while at
the same time having a high recognition factor. 


Numbers 1, 5, 6, 8, 9 of the big and most of the square logos I like in
this respect. Also, matching pairs of large and square logos would be
good. 


Like some others, in my sketch I tried  to include the colors of the
Apache feather. This is quite good for corporate identity, although a
blue/yellow version might look good, too. I tried to show the "openness"
of OpenMeetings through the transparency of the circles and the
"meeting" through the overlapping circles. 


Apart from my own suggestion, I really like the current logo by Denis
Kandrov. However, for the square version, one might find something with
more similarity to the big version. 

What do you think? 


Many greetings,
Thomas 


@Maxim Thanks for uploading my corrected logo

Maybe you also have to change the favicon.svg file in that folder. Also
try to clear the browser cache. Or close the browser completely and open
open meetings in a private tab.

Re: Login loop when using hash invitation

[Thomas Scholzen]

Hi Maxim,

thanks for your help. The problem is that by using a link a second time 
within the valid period (or endless link) there is no login possible. If 
the "access denied" page would appear, the user could logoff. But 
instead the circling login icon is going on endlessly. Only when 
shortening the link to the domain without the hash, the user can logout 
and subsequently login with the complete invitation link.

Bug in translation

I found a misleading error in the German translation of openmeetings. Is 
there a way to report this without joining the localization project?

When entering a wrong URL for an invitation the English error message 
is: "The invitation code is invalid", while the German message says "Die 
Einladung ist nicht mehr gültig.", which means "The invitation is no 
longer valid". So the user thinks, the URL is okay but has expired.

Hi Maxim,

thanks for your reply. The error message "The invitation code is

Hi everyone,

I found a misleading error in the German translation of openmeetings. 
Is there a way to report this without joining the localization project?


sure this mailing list is a great place to do it :)

Best regards,
Thomas

When entering a wrong URL for an invitation the English error message 
is: "The invitation code is invalid", while the German message says 
"Die Einladung ist nicht mehr gültig.", which means "The invitation is 
no longer valid". So the user thinks, the URL is okay but has expired.

Could you please share a better translation?
I don't speak German unfortunately :(

log4j vulnerability

[Thomas Scholzen]

Openmeetings has, among others, the following dependencies:

log4j-over-slf4j-1.7.32.jar
slf4j-api-1.7.32.jar
jcl-over-slf4j-1.7.32.jar

Does anyone know, whether these are affected by the log4j vulnerability 
CVE-2021-44228 and have to be updated?


Thanks,
Thomas

Afaik we are not using the native log4j library. I think the 
vulnerability is only in the actual log4j.jar file.


log4j-over-slf4j is merely a bridge that mimics log4j APIs in order to 
redirect the log stream into slf4j without rewriting the existing 
log4j logging statements. The bridge ensures old dependencies that 
have not been migrated to SLF4J can work with Openmeetings.


So OpenMeetings is not using or distributing the native log4j JAR 
library. Also the Tomat version we are using that bundles OpenMeetings 
into a Java Servlet Container is not affected since it's not using the 
native log4j jar file.


So as far as I can see this vulnerability should not impact OpenMeetings.

However OpenMeetings regularly ships updates with the latest libraries 
and dependencies, so if you are not using the latest version, you 
should update. There have been other CVE's fixed in recent versions.

Re: Media server connection is failed, will try to re-connect

[Thomas Scholzen]

Hi Maxim,

the size of the backup was ~ 4 GB. When the upgrade failed, I 
reinstalled OM 7.0.0. When having problems, I also reinstalled coturn & 
docker (plus km). When all failed I asked you ;-). The (re) installation 
was done on the same server on which OM 6.0.0 was running before.

I went for a fresh installation. I installed OM 7.0.0, kurento via

Can you run OM7 at the VM/server you already have for OM6?

I've just have checked the changes
And I would say your migration should be flawless (no real changes in
KMS/Coturn integration)

Maybe you can try to run OM7 nearby OM6?
- different port
OR
- stop one -> start another?

So I suspect an issue with the turnserver. With OM 6.0.0 this setup 
went fine, so there is probably some kind of misconfiguration.

This can be both TURN server issues and network misconfiguration at
new VM/server
"$ docker logs kms" gives me:

"KurentoWebRtcEndpointImpl

config; remember that NAT traversal requires STUN or TURN"

This is more or less expected
I never had enough time to set up TURN inside KMS :(
And everything seems to work at demo server

In /etc/turnserver.conf I have:

static-auth-secret=7xxx
realm=testexample.de [1]
stale-nonce=0
log-file=/var/log/turnserver/turnserver.log
syslog

In webapps/openmeetings/WEB-INF/classes/openmeetings.properties I have:

kurento.turn.url=xxx.yyy.zzz.aaa:3478
kurento.turn.user=

Because I run also other services on this server SSL is done via port 
4443 with a proxy to localhost:5080/openmeetings (see attached apache2 
virtual host config). This makes it a bit complicated, but it was 
working flawless with OM 6.0.0


I Would appreciate if you could give me a hint how to debug this.
BTW "kurento via docker" might be not necessary in your case
KMS7 was released and it natively supports Ubuntu 20 :)

My bad :(
7.0.0 don't use TURN server config set up in OM and uses freeice all
the time :(((

This is fixed,

I can suggest to set up build 235+ from here:
https://ci-builds.apache.org/job/OpenMeetings/job/openmeetings/
(no import/export will be required, just config changes)

Or wait for release of 7.1.0 (hopefully will be released in couple of weeks)

build 235 is installed at

expected

sorry for inconvenience :(

However, I can not get media transmission from other users. I tried different
