Scott Hanselman on Programming, The Web, Open Source.NET, The Cloud and More. Downloading and Installing RabbitMQ. The latest release of RabbitMQ is 3.6.10. For release notes, see changelog. First, make sure your server is up- to- date with latest packages and security updates. Login to your server via SSH. Install apt- get key for Big. Blue. Button repository. All packages for Big. Blue. Button are digitally signed with the projects public key. Install API demos (optional)If you want to login to your Big. Blue. Button server through the landing page, install the API demos using the command$ sudo apt- get install bbb- demo. Once installed, you’ll be able to enter your name on the home page and click . Install client self- check (optional)Big. Blue. Button provides an end- user self- check application that can help you diagnose networking and configuration issues that may be preventing an end- user from accessing the server. To install the end- user self- check application, enter the command$ sudo apt- get install bbb- check. The self- check application is available at your Big. Blue. Button server’s IP address (or hostname) with /check appended. Restart your server. You can restart and check your Big. Blue. Button server at any time using the commands$ sudo bbb- conf - -restart. The bbb- conf - -check scans some of the log files for error messages. They are for testing purposes only. You can then use the bbb- conf setip command to configure Big. Blue. Button to use that domain name, for example: # bbb- conf - -setip bigbluebutton. Obtain an SSL certificate. Before you can configure nginx on Big. Blue. Button to server content via HTTPS, you need to have a valid SSL certificate. A domain validated (sometimes called “class 1”) certificate with a 2. RSA key and SHA- 2. There are a number of providers that you could obtain a certificate from. Many domain name sales companies also offer certificates. Some well known large providers of SSL certificates include Comodo, Symantec, Go. Daddy, Global. Sign, and Digi. Cert. In addition, free SSL certificates are available from Start. SSL and CACert, with some caveats: Start. SSL certificates can’t be revoked without paying a service fee, and most people do not have the root for CACert installed in their web browser. Each provider will give you a series of steps for generating the certificate, but they will normally include generating a private key and certificate request locally, sending the certificate request to be signed, and then receiving back the signed certificate after they have performed any required verification steps. To install the certificate in Big. Blue. Button, you will need to have files for the certificate, private key, and any intermediate certificates in PEM format. If you don’t yet have a SSL certificate and your server is on the Internet, you can use Let’s Encrypt to obtain a free renewable SSL certificate (expires after 9. In addition, fix the permissions so that only root can read the private key: # cat > /etc/nginx/ssl/bigbluebutton. END'. Paste the contents of your key file here. And the certificate file. Note that nginx needs your server certificate and the list of intermediate certificates together in one file (replace the hostname in the filename with your own): # cat > /etc/nginx/ssl/bigbluebutton. END'. Paste (in order) the contents of the following files. The signed certificate from the CA. In order, each intermediate certificate provided by the CA (but do not include the root). This step can take several minutes to complete, particularly if run on a virtual machine.# openssl dhparam - out /etc/nginx/ssl/dhp- 2. Now we can edit the nginx configuration to use SSL. Edit the file /etc/nginx/sites- available/bigbluebutton to add the marked lines. Ensure that you’re using the correct filenames to match the certificate and key files you created above. Please note that recommended SSL settings are subject to change as new vulnerabilities are found. Configure Free. SWITCH for using SSLEdit the file /opt/freeswitch/conf/sip. Change the line so it matches the following (note the change of ws- binding to wss- binding and port 5. When a user successfully. Edit /usr/local/bigbluebutton/core/scripts/bigbluebutton. A well- respected site that can do a series of automated tests is https: //www. Do not show results” check box if you would like to keep it private, then Submit. At time of writing, the configuration shown on this page should achieve an “A” ranking in the SSL Labs test page. Using Let’s Encrypt. If you have a domain name assigned to your Big. Blue. Button server (i. Your certificate and chain have been saved at. Your cert will. expire on 2. XX- YY- ZZ. To obtain a new version of the certificate in. Let's Encrypt again. Ensure that you’re using the correct filenames to match the certificate and key files you created above (again, replace bigbluebutton. The output will be piped to a log file located at /var/log/le- renewal. To finish the SSL configuration, continue with the steps at Configure Free. SWITCH to user Web. RTC. Configuring Big. Blue. Button behind a firewall. Updating Free. SWITCH configuration. As described in the introduction, a common setup is to have your Big. Blue. Button server behind a firewall (either virtual or physical). Do you want to try Flash instead? Error. Detected the following Web. RTC issue. Probable Cause. Could not make a Web. Socket connection. Note 1. 10. 07: ICE negotiation failed. Note 2. For Error 1. IP address for proxy. If you continue to see the Error 1. Configure a dummy NIC. For Error 1. 00. 7, it means that the web socket connect was successful (Free. SWITCH is running and received the request from the browser to setup a media path), but none of the IP/Port combinations returned by Free. SWITCH enabled the browser to connect and start transmitting media. To diagnose this error, open about: webrtc in Fire. Fox and click . Look under the column Remote Candidate and check if you see the internal IP address of the Big. Blue. Button server. If so, you probably have a misconfiguration in the Free. SWITCH settings. Re- check against the examples shown above. If the correct IP address is shown, you probably have an issue where your firewall isn’t allowing UDP packets through in both directions on the required ports. Check your firewall documentation for help, or ask the Big. Blue. Button community mailing list. Configure a dummy NIC (if required)If you are encountering error 1. Web. RTC audio, it might be that your firewall does not support “hairpin NAT”, which means when the Big. Blue. Button server connects to the firewall’s IP address, the firewall is not sending the connection right back. You can test if hairpin NAT is working using following command on your Big. Blue. Button server. Replace EXTERNAL. This will cause it to use the correct IP address on the response. To setup a dummy NIC, on your Big. Blue. Button enter the following command and substitute EXTERNAL. This will give a long string of random numbers that will be impossible to reverse engineer. Run the command sudo bbb- conf - -setsecret new. In addition, to preserve the backup of the original raw media, you should transfer the contents of the /var/bigbluebutton/recording/raw directory. Here is an example set of rsync commands that would accomplish this; run these on the new server to copy the files from the old server. The downside is that this can take a long time, and will use a lot of CPU on your new Big. Blue. Button server while you wait for the recordings to process. If your old server has all of the original recording files in the /var/bigbluebutton/recording/raw directory, then you can transfer these files to the new server, for example with rsync: This example rsync command could be run on the new server, and will copy the recording file from the old server. Any method should work fine. You will then need to fix the permissions on the newly copied recordings: $ chown - R tomcat. And initiate the recording re- processing$ bbb- record - -rebuildall. The Big. Blue. Button server will automatically go through the recordings and rebuild and publish them. You can use the bbb- record - -watch command to see the progress. Install callback for events (webhooks)Want to receive callbacks to your application when an event occurs in Big. Blue. Button? Big. Blue. Button provides an optional web hooks package that installs a node. Big. Blue. Button and sends POST requests with details about these events to hooks registered via an API. Scroll down to the entry named Videoconf. Module. The value of the video. Quality attribute can be anywhere from 0 to 1. Quality of 1. 00 means no video compression will be done at all, and you will get maximum quality at the expense of bandwidth. If the bandwidth is low, the frame rate will suffer. For more information see Client Configuration. Change the /client/Big. Blue. Button. html portion of the URLUsing nginx, you can rewrite the incoming URL for /client/Big. Blue. Button. html to appear as a different link, such as /conference/. First, modify /etc/bigbluebutton/nginx/client. Big. Blue. Button. To do so, open config. Share. Only=. Do you want to try flash instead? To enable Chrome to access the user’s microphone, see Configuring HTTPS on Big. Blue. Button. Tomcat. Tomcat relies on the Secure. Random class (which uses available entropy) to provide random values for its session IDs. However, if the IP address changes (such as when rebooting a VM), or the first IP address was not the correct IP address for the server, you may see a “Welcome to nginx” page. To reconfigure the Big. Blue. Button to use the correct IP address or hostname, see Big. Blue. Button does not load. Big. Blue. Button does not load. If your has changed it’s network connection (such as on reboot), you can most of Big. Blue. Button’s configuration files with the following steps. This might be caused by a misconfiguration in Free.
