FreeSWITCH fails to bind to port 8021

[Chee-Kian Tan]

Hi Fred and all,

I receive this error "Thread ended for mod_event_socket" everytime when I run bbb-conf --restart / --check. My server is hosted on Ali cloud and it doesn't support IPv6. I followed the recommended method and everything seems to be working when I test it. 

Is the error indicating the error still exists ? I tried bbb-conf --clean to clean the logs but it doesn't seem to help.

Also, I am having Error 1002 even thought I followed this solution to configure my server behind the firewall.

systemctl status freeswitch output:

curl --trace-ascii - -k https://EXTERNAL_IP_ADDRESS:443/bigbluebutton/api output:

Are these two issues related ? Any suggestions to fix them ?

Thanks,

CK

Hi Chee-Kian,

Can you try testing your access from another computer

  http://docs.bigbluebutton.org/install/install.html#testing-the-firewall

Also, check the section on setting up access to FreeSWITCH behind a firewall

  http://docs.bigbluebutton.org/install/install.html#updating-freeswitch-configuration

especially the text related to 1002 error.

Regards,... Fred

Hi Fred,

I did test the port from another computer with netcat. The ports are opened.

I also followed the instructions to fix the Error 1002, but, still no luck for now. 

My ECS server was given a private IP (172.19.129.19) and public IP (47.100.xx.xx). 

/opt/freeswitch/conf/vars.xml

<X-PRE-PROCESS cmd="set" data="external_rtp_ip=47.100.xx.xx"/>

<X-PRE-PROCESS cmd="set" data="external_sip_ip=47.100.xx.xx"/>

/opt/freeswitch/conf/sip_profiles/external.xml

    <param name="ext-rtp-ip" value="$${external_rtp_ip}"/>
    <param name="ext-sip-ip" value="$${external_sip_ip}"/>

/usr/share/red5/webapps/sip/WEB-INF/bigbluebutton-sip.properties

bbb.sip.app.ip=<172.19.129.19>
bbb.sip.app.port=5070

freeswitch.ip=<172.19.129.19>
freeswitch.port=5060

Am I doing this right ?

Thanks,

CK

Hi Fred,

The WebRTC issue has been resolved. I accidentally enter the wrong port , :7433 instead of :7443. But the sip and screenshare still failed. 

The screenshare features allow me to download the java app but not start the screenshare.

Thanks,

Did you try the netcat test with port 1935? That's the RTMP port and is required for bbb-apps connections and for the screensharing app.

[Chee-Kian Tan]

Hi Fred,

I did. The netcat test returned a success test to all required TCP and UDP ports.

Thanks,

CK

What's the output from "bbb-conf --check". I just noticed what the actual error was for the RTMP sip connection and it seems to suggest the sip red5 app is not running or doesn't exist.

What do you see when you try to join a meeting? Can you load the client? Do you see "[Tunnelling]" in the lower right corner?

I'm not sure what it is. All I can tell is that even loading a the page on that server takes more than 20 seconds so if all the requests to connect are also taking that long to respond I wouldn't be surprised to see the connections timeout. I'm not really sure why your server would be so slow to respond though.

You also might want to try BBB 2.0 instead of BBB 1.1. I think I have a memory of maybe some bugs getting fixed related to not having IPv6, but I can't be certain.
