IMUNES on Linux
The IMUNES open-source network simulator can now be installed on and run on Linux. Previously, IMUNES was available only for the FreeBSD operating system.
The Linux version of IMUNES is ready to be used and can set up and run network emulation scenarios. It does not yet have all the features offered in the FreeBSD version of IMUNES but the development team intends make add in more features until both versions support similar capabilities.
In this post, we will show how to install the Linux version of IMUNES on Ubuntu 14.04, look at the tool set used by IMUNES on Linux, and experiment with a simple network simulation scenario.
Compatibility with Linux versions
IMUNES is compatible with all popular Linux distributions.
The IMUNES development team seems to be testing IMUNEs on the latest available Linux distributions. If you are using Linux distributions like Ubuntu 15.04, you can follow the standard IMUNES install directions. However, if you are using a long-term-supported distribution like Ubuntu 14.04, there are some extra software dependencies that you must install.

Where Should WAN Functionality Live?
Improving outdated WAN architecture is not a simple decision, due to the growing number of technology options and services.Risky Business #378 — Mary Ann Davidson vs Krebs and Dowd
On this week's show we're chatting with Mark Dowd and Brian Krebs about Oracle CSO Mary Ann Davidson's somewhat odd blog post from earlier this week. In the post she laid into security researchers for violating Oracle's EULA when reverse engineering their products. The post got pulled, much drama, we sift through the ashes of that. Plus we chat to Brian about the daring $46.7m online heist against Ubiquiti Networks.
Datanauts 006 – Assessing IPv6 Readiness
New IPv4 address space is almost gone from the global market. Organizations need to introduce IPv6 into their environments to ensure uninterrupted business operations with the rest of the world. Yet, implementing IPv6 is not as simple as firing up a routing scheme. How does an organization know if it’s ready? Special guest Ed Horley joins the Datanauts in this discussion.

Using Vagrant with CumulusVX
Cumulus recently announced their CumulusVX platform, which is a virtualized instance of their operating system typically found on network switches. They’ve provided a few options to run this, and in this blog post, I’ll be exploring the use of Vagrant to set up a topology with Cumulus virtual devices. Brief Review of Vagrant In software development, there is a very crucial need to consistently and repeatably set up development and test environments.Using Vagrant with CumulusVX

Brief Review of Vagrant
In software development, there is a very crucial need to consistently and repeatably set up development and test environments. We’ve had the “but it worked on my laptop” problem for a while, and anything to simplify the environment set up and ensure that everyone is on the same page will help prevent it.
Vagrant is a tool aimed at doing exactly this. By providing a simple CLI interface on top of your favorite hypervisor (i.e. Virtualbox) you can distribute Vagrantfiles, which are essentially smally Ruby scripts, and they provide the logic needed to set up the environment the way you want it. In addition, it can call external automation tools like Ansible and Puppet to go one step further, and actually interact with the operating system itself to perform tasks like installing and configuring software.
What we get out of a tool like Vagrant is a Continue reading
