RemoteLabs 3 Client Help Pages

System Requirements

Please make sure that your device complies with the following system requirements.

1. General Description

The Remote Labs Client provides a simple and easy to use access to the Fast Lane Remote Lab Services. The Remote Labs Client Installer is available in the Download section.

At the moment the Remote Lab Client supports the Windows and MacOS operating system. Please refer to the relevant requirements sections for more information.

2. Facility Requirements

Bandwidth

56 kBit/s or higher multiplied with the number of Student- PCs. We recommend for 1-4 Pods: 400kBit/s, for 5-8 Pods: 700kBit/s and for 8-16 Pods: 1MBit/s. *If you are using a shared line e.g. for parallel trainings, ensure that you have enough bandwidth for each class.

Proxy

It is not possible to access the Fast Lane Remote Lab System directly using a Proxy. If a Proxy must be used due to company policies, please use the following solution.

Please contact our Support for further help.

Step 1: Download and Install the Client

In order to make sure that the Remote Labs Client works with your device, please read the System Requirements. Afterwards, please download the right version for your OS in the download area and open the file.

Windows: On Windows it will automatically install the RemoteLabs 3 Client on your system. The picture below shows the installation dialog:
Mac OS: On Mac OS open the downloaded *.dmg file and just drag and drop the Application into your Applications folder:

Step 2: Login

By checking the box "remember my login on this computer", the user name is prefilled the next time the client is started, with the last entry of a successful login.

If you don't have an account yet, click "Create Account" on the login page to create your own:

Step 3: Dashboard

After Login your Dashboard will open up:

This is the overview for all Labs you're currently attending. Please add the Lab you want to join like this:

When you've successfully entered the AccessCode, which will be provided by your trainer, your Lab will appear on the Dashboard:

Step 4: Your Lab

Click on the "VIEW LAB" button and your Lab will open up:

The Lab View is separated in these three secitions:

Side Menu: The Side Menu enables you to switch between Exercises and Excercise Groups. This is also the menu used to load a configuration into your lab environment.
Lab Topology: The Lab Topology is used to show you the lab structure. It will show you how the Devices in your Lab Environment are arranged and give you an impression on how they are interconnected.
Lab Guide: The Lab Guide is used to place your Learning Material. You can click to switch Tasks and have a look at Exercises and Informations about the Lab.
This is also the place where Login Credentials are normally provided.

Opening a connection:

In your Lab choose a connection you would like to open from the "Lab Topology" and double click it.
If you have selected X2Go as your connection technology (see Settings) a dialog will open over your Topology diagram and indicate connection progress.
Your connection window will appear on your screen and you can start using it.

Step 5: Settings

On your Dashboard, you're able to get to the clients settings page when you click on your Name in the upper right corner of the screen.

Profile: Here you can change your Name and Password.
Connection: The client offers two connection types, X2Go and Guacamole. While X2Go is a long established and proven connection type in the RL3Client, Guacamole is still in the beta phase.
You can configure the initial resolution of connections by RDP and the Keyboard Layout used in this kind of connection. If you use the connection type Guacamole, the keyboard layout is determined automatically.
If you selected X2Go as connection type you need to allow outbound connections created by X2go.
Connection Check: The test tries to establish connections to all Fast Lane services. The results are listed by service. In order to implement appropriate rules in a firewall, please have a look a the facility requirements

Connection Control Bar

The Connection Control Bar is available for connections using the Guacamole protocol. It contains several control elements for a remote connection. Depending on the connection type and the user's permissions, a different number of control items are displayed.

To display / hide the control the user can either click on the small arrow at the top left of the connection window or type Ctrl+ Alt + Shift + Space.

Copy and Paste

To copy between your and the remote computer, the RL3Client uses special key combinations instead of Ctrl+c, Ctrl+x or Ctrl+v when connecting via the Guacamole protocol (for details have a look at the Shortcuts section).

This ensures that copying (with Ctrl+c) and pasting (with Ctrl+v) work as usual on the remote device.

Have a look at the following video for a detailed explanation of the described behavior:

Connection Test

The Connection Test ensures that all your connection requirements are met. We'll establish test connections to our infrastructure to make sure you've got optimal connectivity to our labs.

Please log in to the client with your Fast Lane Account and open the Settings.
Run the Connection Test.
If a red cross appears, please ensure that your system meets our System Requirements.
