Now, let's get down to the exciting part: installing EVE-NG! This is where we bring our virtual network lab to life. Follow these steps carefully, and you’ll have EVE-NG up and running in no time. First, let's update your Ubuntu system and install the required packages. Open your terminal and run the following commands. These commands ensure that your system is up-to-date and has all the necessary dependencies. Type sudo apt update and press Enter. This command updates the package lists for upgrades and new package installations. Next, type sudo apt upgrade and press Enter. This command upgrades all the installed packages to their latest versions. It's always a good idea to update your system before installing new software. Once your system is updated, install the necessary dependencies for EVE-NG. Run sudo apt install qemu-kvm libvirt-bin bridge-utils virt-manager -y. This single command installs the core components required for EVE-NG to function, including QEMU for virtualization, libvirt for managing virtual machines, and bridge-utils for networking configurations. The -y flag automatically answers 'yes' to any prompts during the installation, making the process smoother. Next, download the EVE-NG installation file. You can usually find the latest version on the official EVE-NG website. Then, navigate to the directory where you downloaded the EVE-NG ISO file in the terminal. Once you're in the correct directory, you will need to prepare the EVE-NG image for installation. We will do this by using a command similar to the following: sudo bash /path/to/eve-ng_x.x.x-xxx.iso. Make sure to replace /path/to/ with the actual path where you have stored your image. After you’ve executed the command, follow the on-screen prompts. During the installation, you'll be asked a few questions. Make sure you select the correct network interface. Typically, this is your primary network interface, such as eth0 or enp0s3. Choose the appropriate settings for your network configuration. Finally, after the installation has completed, you'll be prompted to reboot your system. Go ahead and reboot your Ubuntu desktop. After the reboot, access EVE-NG through your web browser. Open your web browser and navigate to the IP address of your Ubuntu machine. You should be greeted with the EVE-NG login screen. The default login credentials are Username: root and Password: eve. After logging in, you're ready to start building your network topologies.

Configuring Network Settings for EVE-NG

Alright, now that you've installed EVE-NG, let's make sure your network settings are properly configured. This is crucial for your virtual devices to communicate with each other and with the outside world. This part is about setting up the network bridges and interfaces so that your simulated network can interact with your physical network. First, let’s configure the network bridge. EVE-NG uses network bridges to connect your virtual machines to your physical network. This allows your virtual devices to access the internet and communicate with other devices on your local network. You can typically configure the network bridge during the initial setup of EVE-NG. If you did not do it at that time, you can edit the /etc/network/interfaces file to create a bridge. If you're using a graphical interface, you can also manage network bridges through the network manager. Make sure you understand how the network settings work, especially the IP addressing. Ensure that your EVE-NG instance has a static IP address to prevent it from changing. This static IP address is essential for remote access and for accessing the EVE-NG web interface. You can set a static IP address by editing the network configuration files or by using the network manager. Make sure your firewall settings allow traffic to and from the EVE-NG instance. Inbound traffic needs to be allowed for you to access EVE-NG, and outbound traffic needs to be allowed for your virtual devices to access the internet. Configure DNS settings to allow your virtual machines to resolve domain names. Proper DNS settings ensure that your virtual machines can reach external resources. Verify your network configuration by testing connectivity. You can do this by pinging devices inside your EVE-NG environment and by pinging external resources like Google. Troubleshooting network issues is crucial if something goes wrong. If you run into any problems, check the network configuration files, ensure that the network bridges are correctly configured, and verify that the firewall rules are correct. Network configuration is key to the functionality of EVE-NG, so taking the time to set it up correctly will save you headaches later. If you are having issues with network connectivity, try restarting the network services or rebooting your EVE-NG instance.

Adding and Using Network Devices in EVE-NG

Time to add some devices and get your hands dirty building network topologies! This is where the fun really begins. EVE-NG supports a wide variety of network devices, including routers, switches, firewalls, and more. First, you'll need to upload the images of your desired network devices. You'll typically get these images from the vendor or through your organization. Then, use the EVE-NG web interface to upload these images to the correct directory on your EVE-NG server. Once the images are uploaded, you can start adding them to your network diagrams. Create a new lab by clicking on 'Add New Lab'. Give your lab a descriptive name. Drag and drop the devices from the device menu onto the canvas. You can add routers, switches, and other network devices. Then, configure the devices by right-clicking on a device and selecting the appropriate settings. Configure the device interfaces, IP addresses, and routing protocols, just as you would with real-world devices. Connect the devices by drawing connections between their interfaces. Use the appropriate cable types for your devices (e.g., Ethernet, serial). Configure the interfaces on your devices so they can communicate with each other. Assign IP addresses and configure routing protocols. Test the connectivity. After the devices are configured and connected, test their connectivity by pinging between devices. This will confirm that your network topology is set up correctly. Start the devices. Power on each of the devices you've added to your lab and wait for them to boot up.
