hi,

centos/rhl sometimes act a bit strange because of security.

turn off selinux or chcon -R -t httpd_sys_content_t /path/to/red5/ might help...

Greetings Peter

Are you testing screen-sharing app on CentOS?
According to your screen-shots it is most probably windows machine.

In this case screensharing.log will be in your home folder at Windows
machine ......

Why are thinking your screen-sharing app is blocked by the FW?

I  look file "cat /opt/red5401/conf/red5.properties|grep port", as I see ports 
list:
843
5080
5443
1935
8443
8088
8081
1936
1935
9999
9998

I add all this ports to exception by "firewall-cmd --add-port=%port from list, up%/tcp" , 
"firewall-cmd --add-port=%port from list, up%/udp"
Then "systemctl restart firewalld.service"
Whatever, openmeetings doesn’t work in my local network from other machines, 
only from https://localhost:5443
Maybe something more I need to add to exception. Not only ports? Can you give 
me advice?

Subject: RE: firewalld settings on Centos7

I see my file /home/user/screensharing.log but last what I see I date 20180111. 
I reboot centos7, repeat error, but I don’t see in screensharing logs for 
20180112. Even more after reboot centos7  I enable firewalld to start it 
automatically, and now I can't access to openmeetings. If I stop service 
firewalld it is works as expected. What rules should I add to firewalld? In my 
case I got https over http, other settings is default. I can't see in 
screensharing errors to repeat it, I don’t understand why in this file doesn’t 
exist yet strings for today.

Ports you have to open depends on your red5 server configuration Please check 
screensharing.log file (on client machine, in HOME
folder) and ensure what protocol/port is being used And what is the error

I on firewalld.service and add rules:
firewall-cmd --add-port=5443/tcp

firewall-cmd --add-port=1935/tcp

But I got error when I try to “start record”, see screenshot attached.

Did I something miss, add more rules? I use https, at last I configure
https, but I don’t configure rtmps because I think it is no need to do this.
So minimal is done 5443,1935 ports add to exception.
