Install the CORE Network Emulator from source code

To install the CORE network emulator in recently released Linux distributions, including Ubuntu 16.04 and later, you must install it from source code. There is a bug in CORE that prevents Quagga from starting its routing daemons in newer Linux distributions that is fixed in the latest version of the source code. However, the fix is not in the pre-built CORE packages available on the CORE web site, nor in the Ubuntu repository.

To further create problems, the CORE web site contains old versions of source code and does not point to the latest version of CORE on Github.

Also, the Ubuntu maintainers will remove CORE packages from the Ubuntu repository in the near future because CORE allows unprivileged users to access root privileges, which creates a security problem if CORE is run on a computer used by more than one person.

In this post, I provide a detailed procedure to install CORE from the source code on Github, and to set up your system to run network experiments using the CORE network emulator.

Install CORE from Github

The latest version of CORE is available on Github. To install CORE, first install some prerequisite packages that allow you to Continue reading

Certain HP laptops are found recording users’ keystrokes

Over two dozen HP laptop models have been secretly recording users’ keystrokes, possibly by mistake, according to a Swiss security firm.The keylogger is found within the PCs' audio driver software and has existed since at least Dec. 2015, the security firm Modzero said in a Thursday blog post.   The audio driver was designed to identify when a special key on the PC was used. But in reality, the software will capture all the keystrokes and write them in an unencrypted file located on the laptop.In other cases, the keystrokes will be passed to a Microsoft Windows debugging interface on the PC, and expose them to possible capture, Modzero said.      To read this article in full or to leave a comment, please click here

What has OpenStack done for me lately? The next 5 issues to address

This contributed piece has been edited and approved by Network World editors

OpenStack has been on a roll, seeing increased adoption across the business world, highlighted by major deployments from leading organizations like Verizon, BBVA, and NASA Jet Propulsion Laboratory, as well as continued growth in the contributing community. But what’s next?

While it’s nice to see the success of OpenStack in the enterprise, the community cannot rest on its proverbial laurels. Here’s what the OpenStack community and ecosystem need to accomplish next:

* Containers, containers and ... containers.  OpenStack isn’t the hottest open source technology on the block anymore, that title is now owned by Linux containers. An application packaging technology that allows for greater workload flexibility and portability, support for containerized applications will be key to OpenStack moving forward, especially as enterprise interest intersects both Linux containers and OpenStack.

Worth Reading: Lessons from Facebook’s split network backbone

Distributed applications, whether they are containerized or not, have a lot of benefits when it comes to modularity and scale. But in a world of feature creep on all applications, whether they are internally facing ones running a business or hyperscale consumer applications like Google’s search engine or Facebook’s social media network, these distributed applications put a huge strain on the network. This, more than any other factor, is why network costs are rising faster than any other aspect of the datacenter. —The Next Platform

HPE offers an escape from the aging HP-UX OS via containers

Hewlett Packard Enterprises' HP-UX OS has been around for more than 30 years, and users may be looking to move on from the Unix-based OS.Now HPE is offering a way out of the ancient OS using containers, which are small buckets running instances of applications. The containers will be offered with the Linux OS.HPE will provide containers to transition from conventional mainframe-style OSes to new hardware like x86-based Xeon servers. In this case, HPE is trying to get users to transition from Itanium chips.Intel started shipping its last Itanium 9700 chips -- codenamed Kittson -- on Thursday. Correspondingly, HPE announced new Integrity i6 servers with the new chips. But the future of HP-UX servers is uncertain because Intel has no new Itanium chips beyond Kittson.To read this article in full or to leave a comment, please click here

Bringing Internet to Venezuela’s Remote Regions – While Setting a World Record

My interest in networking began during my time as a professor and head of the telecommunications lab at the University of Los Andes, in Merída, Venezuela, where we began experimenting with computer networks. I was one of the earliest Internet enthusiasts at our university.  Our university was the first in Venezuela to get direct access to the Internet backbone in Homestead, Florida, by means of an antenna on the roof of our lab with the satellite modem in my office.
