How to set up the EVE-NG network emulator on a Linux system

EVE-NG is a graphical network emulator that supports both commercial and open-source router images. It’s graphical user interface runs in a web browser. EVE-NG runs in a virtual machine so it can be set up Windows, Mac OS, or Linux computers.

In this post, I will show how to set up an EVE-NG virtual machine on an Ubuntu Linux system. I’ll show the basic steps to creating and running a simple lab consisting of emulated Linux nodes.

To support more complex labs using open-source routers and other open-source network appliances in EVE-NG, we need to create custom templates and build router images specifically for use in EVE-NG. I will cover these topics in a future post. In this post, we’ll focus only on getting an EVE-NG virtual machine set up and running on a Linux system.

EVE-NG Overview

EVE-NG is a clientless network emulator that provides a user interface via a browser. Users may create network nodes from a library of templates, connect them together, and configure them. Advanced users or administrators may add software images to the library and build custom templates to support almost any network scenario.

EVE-NG supports pre-configured multiple hypervisors on one virtual machine. It runs Continue reading

Installing VirtualBox 5.1 on Fedora 25

Last fall, I wrote a piece about why I had switched to VirtualBox (from VMware Fusion) for my Vagrant needs. As part of my switch to Fedora Linux as my primary laptop OS, I revisited my choice of virtualization provider. I’ll describe that re-assessment in a separate post; the “TL;DR” for this post is that I settled on VirtualBox. As it turns out, though, installing VirtualBox 5.1 on Fedora 25 isn’t as straightforward as one might expect.

After a number of attempts (using a test VM to iron out the “best” procedure), here’s the process I found to be the most straightforward:

  1. Run dnf check-update and dnf upgrade to pick up the latest packages. If a new kernel version is installed, reboot. (I know this sounds contrived, but I’ve run into issues where some kernel-related packages aren’t available for the kernel version you’re actually running.)

  2. Install the RPMFusion repos. You only really need the “free” repository, but you can install the “nonfree” as well if you like (it won’t affect this process). I won’t go through the process for how to do this; it’s really well-documented on the RPMFusion web site and is pretty straightforward.

  3. Next, use Continue reading

BrandPost: Ethernet Ports on PCs Are in for a Long Overdue Speed Boost

Every year, the processing power of the CPUs that drive our computing and gaming devices increases, enabling them to ingest, process, and churn out more data faster. When you look at the increases over time, as the folks at Expert Exchange did in 2015, the progress is nothing short of mind-boggling. They found that an Apple iPhone 5 had 2.7 times the processing power of a 1985 Cray-2 supercomputer. And a pair of 2015 Nintendo gaming systems had about the same processing power as the computer that guided Apollo 11 to the moon. We see it in the new models of workstations, PCs and laptops that come out every year, or even every six months – each one faster and smaller than the last. But, as IDC Research Director Linn Huang points out, the same is not true for the wired Ethernet ports on those machines.To read this article in full or to leave a comment, please click here

US House approves new privacy protections for email and the cloud

The U.S. House of Representatives approved on Monday the Email Privacy Act, which would require law enforcement agencies to get court-ordered warrants to search email and other data stored with third parties for longer than six months. The House approved the bill by voice vote, and it now goes the Senate for consideration.The Email Privacy Act would update a 31-year-old law called the Electronic Communications Privacy Act (ECPA). Some privacy advocates and tech companies have pushed Congress to update ECPA since 2011. Lax protections for stored data raise doubts about U.S. cloud services among consumers and enterprises, supporters of the bill say.To read this article in full or to leave a comment, please click here

DDoS Ransom: An Offer You Can Refuse

DDoS ransom

Cloudflare has covered DDoS ransom groups several times in the past. First, we reported on the copycat group claiming to be the Armada Collective and then not too long afterwards, we covered the "new" Lizard Squad. While in both cases the groups made threats that were ultimately empty, these types of security events can send teams scrambling to determine the correct response. Teams in this situation can choose from three types of responses: pay the ransom and enable these groups to continue their operations, not pay and hope for the best, or prepare an action plan to get protected.

Breaking the Ransom Cycle

We can’t stress enough that you should never pay the ransom. We fully understand that in the moment when your website is being attacked it might seem like a reasonable solution, but by paying the ransom, you only perpetuate the DDoS ransom group’s activities and entice other would be ransomers to start making similar threats. In fact, we have seen reports of victim organizations receiving multiple subsequent threats after they have paid the ransom. It would seem these groups are sharing lists of organizations that pay, and those organizations are more likely to be targeted again in Continue reading

Samsung scraps a Raspberry Pi 3 competitor, shrinks Artik line

Limited stocks of Artik 1020 modules and developer kits are still available for experimentation and small-scale projects," the company said on its Artik website.To read this article in full or to leave a comment, please click here

You’ll see right through this iPhone 8 concept design

Designers are really trying to outdo each other in early 2017, pumping out Apple iPhone 8 design concept videos at a rapid pace in advance of an expected iPhone 8 (or iPhone 10 or iPhone X?) release in the fall. The latest to grab attention -- with more than 61K views on Youtube as of this writing -- envisions a transparent smartphone screen.The design for the iPhone 7 follow-on comes courtesy of Georgy Pashkov via ConceptsiPhone. Featured design elements beyond the transparent screen (with optical sensor) include an ultrasonic fingerprint sensor and piezeoelectric speaker.As for the likelihood of a transparent screen on the actual iPhone 8? Highly unlikely, say Apple watchers. Though advances in Harry Potter-like invisibility cloaks are for real.To read this article in full or to leave a comment, please click here

You can now make smart gadgets and IoT devices that use Bluetooth 5

In a few months, Bluetooth 5 will finally arrive in smartphones and tablets. But you can already test the technology on developer boards being shipped by hardware makers.Bluetooth 5 is a major step ahead for the venerable technology, which was introduced in 1999 to hook up devices wirelessly. It is two times faster than predecessor Bluetooth 4.2, has four times longer range, and boasts cool new connectivity features.It can transfer data at speeds of up to 2Mbps (bits per second) and has a realistic range of 120 meters. The range could be even longer in a clear line of sight, the standards setting organization Bluetooth Special Interest Group said.To read this article in full or to leave a comment, please click here
