Windows 10 Is Getting Linux Files Integration In File Explorer
Microsoft is planning to fully integrate Linux file access into the built-in File Explorer. The Verge reports:
A new Linux icon will be available in the left-hand navigation pane in File Explorer, providing access to the root file system for any distros that are installed in Windows 10. The icon that will appear in File Explorer is the famous Tux, the penguin mascot for the Linux kernel. Microsoft is testing the Linux File Explorer integration in a new build of Windows 10 that's available for testers today. Previously, Windows 10 users would have to manually navigate to a UNC path to get access to Linux files from the Windows Subsystem for Linux (WSL). If you have WSL enabled, then the Tux will appear in File Explorer, and Microsoft is now seeking feedback on the integration before it's finalized as part of a future Windows 10 update. The software maker will ship this update to all Windows 10 users later this year.

# bbb-install

`bbb-install.sh` is a shell script that automates the [step-by-step instructions](http://docs.bigbluebutton.org/2.2/install.html) for setting up a BigBlueButton 2.2 server.

With only a few parameters, `bbb-install.sh` can have your BigBlueButton server set up and ready for use in 30 minutes (depending on your server's internet speed to download and install packages).

For example, given an Ubuntu 16.04 64-bit server with a public IP address, to install/update to the latest build of BigBlueButton 2.2 first SSH into the server as root and run the following command:

~~~
wget -qO- https://ubuntu.bigbluebutton.org/bbb-install.sh | bash -s -- -v xenial-22 -a
~~~

The command will pull down the latest version of `bbb-install.sh`, send it to the BASH shell interpreter, and pass the parameters `-v xenial-22` which specifies you want to install the latest build of BigBlueButton 2.2.N, and `-a` which specifies want to install the API demos (this makes it easy to do a few quick tests on the server).

Note: If your server is behind a firewall -- such as behind a corporate firewall or behind an AWS Security Group -- you will need to manually configure the firewall to forward [specific internet connections](#configuring-the-firewall) to the BigBlueButton server before you can launch the client.

When `bbb-install.sh` finishes, you'll see a message that gives you a test URL to launch the BigBlueButton client and join a meeting called 'Demo Meeting'. 

~~~
# Warning: The API demos are installed and accessible from:
#
#    http://xxx.xxx.xxx.xxx
#
# and
#
#    http://xxx.xxx.xxx.xxx/demo/demo1.jsp 
#
# These API demos allow anyone to access your server without authentication
# to create/manage meetings and recordings. They are for testing purposes only.
# If you are running a production system, remove them by running:
#
#    sudo apt-get purge bbb-demo 
~~~

When you open the URL, you should see a login to join the meeting `Demo Meeting`.


Enter your name and click Join.  The BigBlueButton client should then load in your browser and prompt you to join the audio. 


Click the '[x]' to skip joining the audio.  Why?  With the above command, the BigBlueButton server is configured to only use an IP address (no security) and, as such, the browser will block access to the webcam and microphone.

For a production setup of BigBlueButton, the server needs to serve web pages using transport level security (TLS).  In other words, you can only access this server via `HTTP` (unencrypted) and not `HTTPS` (encrypted), as the server currently lacks a secure socket level (SSL) certificate configured for the server's hostname.

Without TLS/SSL support, the browser will not allow access to the user's webam or microphone via the builtin real-time communications (WebRTC) libraries.

`bbb-install.sh` can automatically request a TLS/SSL certificate (from Let's Encrypt) and configure the BigBlueButton server to use that certificate.  The following sections show you how.


## Getting ready
Before running `bbb-install.sh`, we _strongly_ recommend that you:

  * Read through all the documentation in this page
  * Ensure that your server meets the [minimal server requirements](http://docs.bigbluebutton.org/install/in...quirements)
  * Configure a fully qualified domain name (FQDN), such as `bbb.example.com`, that resolves to the external IP address of the server.

To set up a FQDN, you need to purchase a domain name from a domain name system (DNS) provider, such as [GoDaddy](https://godaddy.com) or [Network Solutions](https://networksolutions.com).  Once purchased, you'll use the web tools provided by the DNS provider to create an `A Record` that resolves to the public IP address of your BigBlueButton server.  (Check the DNS provider's documentation for details on how to set up the `A Record`.)

With a FQDN domain name place, you can then pass a few additional parameters to `bbb-install.sh` to have it:

  * Request and install a 4096 bit TLS/SSL certificate from Let's Encrypt (we love Let's Encrypt), and (optionally)
  * Install and configure [Greenlight](http://docs.bigbluebutton.org/greenlight...rview.html) to provide a simple front-end for users to enable them to set up rooms, hold online sessions, and manage recordings.  (Greenlight also lets you, the administrator, manage user accounts within Greenlight).

Once the BigBlueButton server is configured with an TLS/SSL certificate, your users can use FireFox and Chrome (recommended browsers) to access and share their audio, video, and screen in a BigBlueButton session via WebRTC.

The full source code for `bbb-install.sh` is [here](https://github.com/bigbluebutton/bbb-install).  To make it easy for anyone to run the script with a single command, we host the latest version of the script at [https://ubuntu.bigbluebutton.org/bbb-ins...nstall.sh).


### Server choices

There are many hosting companies that can provide you virtual and dedicated servers to run BigBlueButton.  We list a few popular choices below.  Note: We are not making any recommendations here, just listing some of the more popular choices.

For quick setup, [Digital Ocean](https://www.digitalocean.com/) offers both virtual servers with Ubuntu 16.04 64-bit and a single public IP address (no firewall).  [Hetzner](https://hetzner.cloud/) offers dedicated servers with single IP address.

Other popular choices, such as [ScaleWay](https://www.scaleway.com/) (choose either Bare Metal or Pro servers) and [Google Compute Engine](https://cloud.google.com/compute/), offer servers that are set up behind network address translation (NAT).  That is, they have both an internal and external IP address.  When installing on these servers, the `bbb-install.sh` will detect the internal/external addresses and configure BigBlueButton accordingly. 

Another popular choice is [Amazon Elastic Compute Cloud](https://aws.amazon.com/ec2).  We recommend a `c5.xlarge` (or larger) instance.  All EC2 servers are, by default, is behind a firewall (which Amazon calls a `security group`).  You will need to manually configure the security group before installing BigBlueButton on EC2 and, in a similar manner, on Azure and Google Compute Engine (GCE).  (See screen shots in next section.)

Finally, if `bbb-install.sh` is unable to configure your server behind NAT, we recommend going through the [step-by-step](http://docs.bigbluebutton.org/2.2/install.html) for installing BigBlueButton.  (Going through the steps is also a good way to understand more about how BigBlueButton works).


### Configuring the firewall

If you want to install BigBlueButton on a server behind a firewall, such an Amazon's EC2 security group, you first need to configure the firewall to forward incoming traffic on the following ports:

  * TCP/IP port 22 (for SSH)
  * TCP/IP ports 80/443 (for HTTP/HTTPS)
  * UDP ports in the range 16384 - 32768 (for FreeSWITCH/HTML5 client RTP streams)

If you are using EC2, you should also assign your server an [Elastic IP address](https://docs.aws.amazon.com/AWSEC2/lates...s-eip.html) to prevent it from getting a new IP address on reboot.

On Microsot Azure, when you create an instance you need to add the following inbound port rules to enable incoming connections on ports 80, 443, and UDP port range 16384-32768:


On Google Compute Engine, when you create an instance you need to enable traffic on port 80 and 443.


After the instance is created, you need to add a firewall rule to allow incoming UDP traffic on the port range 16384-32768.


### Installation Videos

Using Digital Ocean as an example, we put together this video to get you going quickly: [Using bbb-install.sh to set up BigBlueButton on Digital Ocean]().

Using Amazon EC2, see [Install using bbb-install.sh on EC2]().

## Install and configure with an IP address only

To install BigBlueButton 2.2 (no hostname or TLS/SSL certificate):

~~~
wget -qO- https://ubuntu.bigbluebutton.org/bbb-install.sh | bash -s -- -v xenial-22
~~~

That's it.  The installation should finish in about 15 minutes (depending on the server's internet connection) with the following message:

~~~
** Potential problems described below **

......
# Warning: The API demos are installed and accessible from:
#
#    http://xxx.xxx.xxx.xxx/demo/demo1.jsp
#
# These API demos allow anyone to access your server without authentication
# to create/manage meetings and recordings. They are for testing purposes only.
# If you are running a production system, remove them by running:
#
#    sudo apt-get purge bbb-demo
~~~

The script also installs the `bbb-demo` package so you can immediately test out the install.  If you want to remove the API demos, use the command

~~~
sudo apt-get purge bbb-demo
~~~

If you want to use this server with a third-party integration, such as Moodle, you can get the BigBlueButton server's hostname and shared secret with the command `sudo bbb-conf --secret`.

~~~
# bbb-conf --secret

      URL: http://xxx.xxx.xxx.xxx/bigbluebutton/
    Secret: yyy

      Link to the API-Mate:
      http://mconf.github.io/api-mate/#server=...Secret=yyy
~~~

Since this default use of `bbb-install.sh` does not configure a SSL/TLS certificate, while you can login to the server, you won't be able to share audio/video as WebRTC requires a SSL/TLS certificate.

## Install with SSL/TLS

Before `bbb-install.sh` can install a SSL/TLS certificate, you will need to provide two pieces of information:
  * A fully qualified domain name (FQDN), such as `bbb.example.com`, that resolves to the public IP address of your server
  * An e-mail address

When you have set up the FQDN, check that it correctly resolves to the external IP address of the server using the `dig` command.

~~~
dig bbb.example.com @8.8.8.8
~~~

Note: we're using `bbb.example.com` as an example hostname. You would substitute your real hostname for the check (and for the commands below).

With just these two pieces of information -- FQDN and e-mail address -- you can use `bbb-install.sh` to automate the configuration of the BigBlueButton server with a TLS/SSL certificate.  For example, to install BigBlueButton 2.2 with a TLS/SSL certificate from Let's Encrypt using `bbb.example.com` and `info@example.com`, enter the command

~~~
wget -qO- https://ubuntu.bigbluebutton.org/bbb-install.sh | bash -s -- -v xenial-22 -s bbb.example.com -e info@example.com
~~~

(again, you would substitute `bbb.example.com` and `info@example.com` with your server's FQDN and your e-mail address).

The `bbb-install.sh` script will also install a cron job that automatically renews the Let's Encrypt certificate so it doesn't expire.  Cool.

### Installing in a private network

The default installation is meant to be for servers that are publicly available. This is because Let's Encrypt requires to access nginx in order to automatically validate the FQDN provided.

When installing BigBlueButton in a private network, it is possible to validate the FQDN manually, by adding the option `-x` to the command line. As in:

~~~
wget -qO- https://ubuntu.bigbluebutton.org/bbb-install.sh | bash -s -- -v xenial-22 -s bbb.example.com -e info@example.com -x
~~~

Confirm the use of the email account.

```

Before continuing, verify the record is deployed.
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Press Enter to Continue
```

Before hitting Eneter, create a TXT record in the DNS with the challenge that was generated.

```
_acme-challenge.bbb.example.com.  TXT  "0bIA-3-RqbRo2EfbYTkuKk7xq2mzszUgVlr6l1OWjW8"  60
```

The downside of this is that because Let's Encrypt SSL certificates expire after 90 days, it will be necessary to manually update the certificates. In that case an email is sent a few days before the expiration and the next command has to be executed through the console.

```
certbot --email info@example.com --agree-tos -d bbb.example.com --deploy-hook 'systemctl restart nginx' --no-bootstrap --manual-public-ip-logging-ok --manual --preferred-challenges dns --server https://acme-v02.api.letsencrypt.org/directory certonly
```


## Install API Demos

You can install the API demos by adding the `-a` option.

~~~
wget -qO- https://ubuntu.bigbluebutton.org/bbb-install.sh | bash -s -- -v xenial-22 -s bbb.example.com -e info@example.com -a
~~~

Warning: These API demos allow anyone to access your server without authentication to create/manage meetings and recordings. They are for testing purposes only.  Once you are finished testing, you can remove the API demos with `sudo apt-get purge bbb-demo`.


## Install Greenlight

[Greenlight](https://docs.bigbluebutton.org/greenligh...rview.html) is a simple front-end for BigBlueButton written in Ruby on Rails.  It lets users create accounts, have permanent rooms, and manage their recordings.  It also lets you, as the administrator, manage the user accounts (such as approve or deny users).

You can install [Greenlight](http://docs.bigbluebutton.org/install/green-light.html) by adding the `-g` option.

~~~
wget -qO- https://ubuntu.bigbluebutton.org/bbb-install.sh | bash -s -- -v xenial-22 -s bbb.example.com -e info@example.com -g
~~~

Once Greenlight is installed, it redirects the default home page to Greenlight.  You can also configure GreenLight to use [OAuth2 authentication](http://docs.bigbluebutton.org/greenlight...omize.html).

To launch Greenlight, simply open the URL of your server, such as `https://bbb.example.com/`.  You should see the Greenlight landing page.


To set up an administrator account for Greenlight (so you can approve/deny signups), enter the following commands

~~~
cd greenlight/
docker exec greenlight-v2 bundle exec rake admin:create
~~~

This command will create an admin account and set a default password.  After running this command, login using the given username/password and change the default password. Next, select 'Administrator' and choose 'Organization'.


You can then select 'Site Settings' on the left-hand side and change the Registration Method to 'Approve/Decline'.


You can now contol who creates accounts on your BigBlueButton server.  For more information see [Greenlight administration](http://docs.bigbluebutton.org/greenlight/gl-admin.html).

## Linking /var/bigbluebutton to another directory

The install script allows you to pass a path which will be used to create a symbolic link with /var/bigbluebutton

~~~
wget -qO- https://ubuntu.bigbluebutton.org/bbb-install.sh | bash -s -- -v xenial-22 -m /mnt/test
~~~

This allows users to store the contents of /var/bigbluebutton, which can get quite large in a seperate volume

## Doing everything with a single command

If you want to set up BigBlueButton 2.2 with a TLS/SSL certificate and GreenLight, you can do this all with a single command:

~~~
wget -qO- https://ubuntu.bigbluebutton.org/bbb-install.sh | bash -s -- -v xenial-22 -s bbb.example.com -e info@example.com -g
~~~

Furthermore, you can re-run the same command later to update your server to the latest version of BigBlueButton 2.2.  We announce updates to BigBlueButton to the [bigbluebutton-dev](https://groups.google.com/forum/#!forum/...button-dev) mailing list.


# Install a TURN server

You can use `bbb-install.sh` to automate the steps to [set up a TURN server for BigBlueButton](http://docs.bigbluebutton.org/install/in...urn-server). 
Note: This step is optional, but recommended if your BigBlueButton server is publically available on the internet and will be accessed by users who may be behind restrictive firewalls.

BigBlueButton normally requires a wide range of UDP ports to be available for WebRTC communication. In some network restricted sites or development environments, such as those behind NAT or a firewall that restricts outgoing UDP connections, users may be unable to make outgoing UDP connections to your BigBlueButton server. 

The TURN protocol is designed to allow UDP-based communication flows like WebRTC to bypass NAT or firewalls by having the client connect to the TURN server, and then have the TURN server connect to the destination on their behalf.

You need a separate server (not the BigBlueButton server) to set up as a TURN server. Specifically you need:

  * An Ubuntu 18.04 server with a public IP address

On the TURN server, you need to have the following ports (in additon port 22) availalbe for BigBlueButton to connect (port 3478 and 443) and for the coturn to connect to your BigBlueButton server (49152 - 65535).

| Ports        | Protocol      | Description |
| ------------- | ------------- | ----------- |
| 3478          | TCP/UDP      | coturn listening port |
| 443          | TCP/UDP      | TLS listening port |
| 49152-65535  | UDP          | relay ports range |


We recommend Ubuntu 18.04 as it has a later version of [coturn](https://github.com/coturn/coturn) than Ubuntu 16.04.  Also, this TURN server does not need to be very powerful as it will only relay communications from the BigBlueButton client to the BigBlueButton server when necessary.  A dual core server on Digital Ocean, for example, which offers servers with public IP addresses, is a good choice.

Next, to configure the TURN server you need:

  * A fully qualified domain name (FQDN) with a DNS entry that resolves to the external public IP address of the TURN server
  * An e-mail address for Let's Encrypt
  * A secret key (it can be an 8 to 16 character random string that you create).

With the above information, you can set up a TURN server for BigBlueButton using `bbb-install.sh` as follows

~~~
wget -qO- https://ubuntu.bigbluebutton.org/bbb-install.sh | bash -s -- -c <FQDN>:<SECRET> -e <EMAIL>
~~~

Note, we've omitted the `-v` option, which causes `bbb-install.sh` to just install and configure coturn.  For example, using `turn.example.com` as the FQDN, `1234abcd` as the shared secret, and `info@example.com` as the email address, you can set up a TURN server for BigBlueButton using the command

~~~
wget -qO- https://ubuntu.bigbluebutton.org/bbb-install.sh | bash -s -- -c turn.example.com:1234abcd -e info@example.com
~~~

`bbb-install.sh` uses Let's Encrypt to configure coturn to use a SSL certificate.  With a SSL certificate in place, coturn can relay access to your BigBlueButton server via TCP/IP on port 443.  This means if a user is behind a restrictive firewall that blocks all outgoing UDP connections, the TURN server can accept connections from the user via TCP/IP on port 443 and relay the data to your BigBlueButton server via UDP.

With the TURN server in place, you can configure your BigBlueButton server to use the TURN server by running the `bbb-install.sh` command again and adding the same `-c <FQDN>:<SECRET>`.  For example,

~~~
wget -qO- https://ubuntu.bigbluebutton.org/bbb-install.sh | bash -s -- -v xenial-22 -s bbb.example.com -e info@example.com -g -c turn.example.com:1234abcd
~~~

You can re-use a single TURN server for multiple BigBlueButton installations.

# Next Steps

If you intend to use this server for production you should uninstall the API demos using the command

~~~
apt-get purge bbb-demo
~~~

You can also do a number of [customizations](http://docs.bigbluebutton.org/2.2/customize.html) to your server as well.

## Troubleshooting

### Packaging server is blocked

We are currently hosting the packaging on a Digital Ocean servlet, but recently the IP range for some Digital Ocean servers has been [blocked in some countries](https://www.digitalocean.com/community/q...rom-russia).

If you're having troubles installing, try running the `bbb-install.sh` command but change the value

~~~
https://ubuntu.bigbluebutton.org/bbb-install.sh
~~~

to

~~~
https://packages-eu.bigbluebutton.org/bbb-install.sh
~~~


### Greenlight not running

If on first install Greenlight gives you a `500 error` when accessing it, you can [restart Greenlight](http://docs.bigbluebutton.org/install/gr...docker-run).

### Tomcat7 not running

If on the initial install you see

~~~
# Not running:  tomcat7 or grails LibreOffice
~~~

just run `sudo bbb-conf --check` again.  Tomcat7 may take a bit longer to start up and isn't running the first time you run `sudo bbb-conf --check`.

### Getting Help

If you have feedback on the script, or need help using it, please post to the [BigBlueButton Setup](https://bigbluebutton.org/support/community/) mailing list with details of the issue (and include related information such as steps to reproduce the error).

If you encounter an error with the script (such as it not completing or throwing an error), please open [GitHub issue](https://github.com/bigbluebutton/bbb-install/issues) and provide steps to reproduce the issue.


# Limitations

If you are running your BigBlueButton behind a firewall, such as on EC2, this script will not configure your firewall.  You'll need to [configure the firewall](#configuring-the-firewall) manually.

In order to switch back the Premiere XL to HD menu, please follow these steps.


1. Make sure that the TiVo is connected to the service. Settings & Messages > Settings > Network > Connect to the TiVo Service Now

2. Restart the TiVo box. Go to Settings & Messages > Help > Restart Box.

3. Once back up, go to Settings & Messages > Restart or Reset System > Choose TiVo Menus (Widescreen)

Your apps should now be working again.

1. the o/s in the case of atleast Ubuntu it MUST be Ubuntu Server not the workstation
2. You must install OpenSSH or the random number generator will bomb out

Attached fine the error from yarn

bridge
 
A bridge is a way to connect two Ethernet segments together in a protocol independent way. Packets are forwarded based on Ethernet address, rather than IP address (like a router). Since forwarding is done at Layer 2, all protocols can go transparently through a bridge.
The Linux bridge code implements a subset of the ANSI/IEEE 802.1d standard. [1]. The original Linux bridging was first done in Linux 2.2, then rewritten by Lennert Buytenhek. The code for bridging has been integrated into 2.4 and 2.6 kernel series.
Bridging and Firewalling
A Linux bridge is more powerful than a pure hardware bridge because it can also filter and shape traffic. The combination of bridging and firewalling is done with the companion projectebtables.
Status
The code is updated as part of the 2.4 and 2.6 kernels available at kernel.org.
Possible future enhancements are:

• Document STP filtering
  
• Netlink interface to control bridges (prototype in 2.6.18)
  
• STP should be in user space
  
• Support RSTP and other 802.1d STP extensions
  

• All devices share the same maximum packet size (MTU). The bridge doesn't fragment packets.
  
• Devices must look like Ethernet. i.e have 6 byte source and destination address.
  
• Support promiscuous operation. The bridge needs to be able to receive all network traffic, not just traffic destined for its own address.
  
• Allow source address spoofing. The bridge must be able to send data over network as if it came from another host.
  

• Find out which bridge is the root bridge, find out where it is located, and what internetworking software it runs. Please report this info to the mailing list (or to me directly), so that I can keep a blacklist.
  
• Force the linux bridge to be the root bridge. See what the priority of the current root bridge is, and use the brctl 'setbridgeprio' command to set the priority of the linux bridge to 1 lower. (The bridge with the lowest priority always becomes the root bridge.)
  
• Disable the spanning tree protocol on your linux bridge altogether. In this case, watch out for bridging loops! If you have loops in your topology, and if no bridge in the loop is running the spanning tree protocol, mayhem will come your way, as packets will be forwarded forever. Don't Do This™.
  

After installing OpenSuse Leap 15.1 and a complete LAMP server, I installed phpMyAdmin this worked great accessed MySQL just fine but once an additional host was added I got "Object Not Found" installed fresh copy of the server no site added and all is once again fine.

Any idea's

Keith

I found this answer which fixed my issue of this error message

Try this in a Terminal windows this is using Linux Ubuntu 16.04 and Postfix Ver 3.1.0 and the Webmin interface ver 1.870.
the command will of course work regardless of the webmin use or not

possible solution:

I installed and began the configuration of the firewall two weeks ago, very nice device, a little intimidating but have been googling and watching youtube. I would like to monitor all traffic origins to a particular computer and connection to any ports
