Archives For EVE-NG

The UNetLab and EVE-NG network emulators can become powerful tools for emulating open-source networks. However, When first installed, they support Linux images only in a limited way. Fortunately, it is easy to extend UNetLab and EVE-NG to support powerful, general-purpose Linux router and server images.

In their default configuration, UNetLab and EVE-NG support Linux nodes running boot-able live CD disk images that offer a graphical user interface accessible via VNC. This is not suitable for emulating Linux routers or servers.

To fix this limitation, we will show you how to build a Linux router image for EVE-NG that boots from a virtual hard disk, can be accessed via Telnet to simplify configuration and management, and that has a persistent file system onto which we can install software and modify configuration files.

EVE-NG and UNetLab are graphical network emulators that support both commercial and open-source router images. UNetLab is the current, stable version of the network emulator and EVE-NG is an updated version of the same tool, available as an alpha release. The UNetLab/EVE-NG network emulator runs in a virtual machine so it can be set up Windows, Mac OS, or Linux computers. Its graphical user interface runs in a web browser.

Since it runs in a virtual machine, EVE-NG may be set up on any operating system such as Windows, Linux, or Mac OS. When using the EVE-NG virtual machine on a Linux computer, I had to resolve a few problems related to the way VMware Player works in Linux. In this post, I focus only on the specific issues related to getting EVE-NG working on a Linux system. I’ll also show the basic steps to creating and running a simple lab consisting of emulated Linux nodes. The procedure is the same for UNetLab.
