Feedback after installing BBB on Azure using bbb-install.sh

[DIARRA Sega Oumar]

Hi all,

Just to share that , I used bbb-install.sh to install BBB with Https on Azure. All works great except that after stopping and restarting my VM , I got Webrtc error 1002. After some research i noticed that I needed to ensure that dummy NIC was automatically created on restart, I followed the steps described here:
http://docs.bigbluebutton.org/install/install.html#configure-a-dummy-nic-if-required
In case it might help someone.

Best regards...

Hi Diarra,

Just to confirm, bbb-install.sh does create an dummy NIC at

  https://github.com/bigbluebutton/bbb-install/blob/master/bbb-install.sh#L343

but your saying after reboot this doesn't work?  Did your Azure server get a new IP address on reboot, or did the above command not make the dummy NIC permanent?

Regards,... Fred

Hi Fred,

Seems that It doesn't make it permanent. At least in my case.
 Did your Azure server get a new IP address on reboot ? 

-> No I use a static IP.

Hi,
I've found the same problem on AWS EC2. After restarting the instance, FreeSwitch fails to start up.  Running the following command after restart sorts it:

sudo ip addr add EXTERNAL\_IP\_ADDRESS/32 dev lo

Thanks for posting Diarra!

Regards,
Matt

Hi Matt,

If you edit /etc/network/interfaces, you can add a line to re-apply the loopback.  For example, to setup a loopback for 136.54.134.20 on reboot, add the following post-up command (with a TAB before the command) to  /etc/network/interfaces.

auto lo

iface lo inet loopback

        post-up ip addr add 136.54.134.20 dev lo

After you reboot the BigBlueButton server, the dummy NIC should still be in effect.

Try the above and don't hesitate to reach out if you have any more issues.

Regards,... Fred
