Three Excellent Linux Router Distros + 1 BSD

Filed under
Linux

Special purpose appliance distributions are one of the things that Linux does extremely well. You can find any number of task-specific appliances from either Turnkey Linux or on the VMware Virtual Appliance marketplace. In this article we'll take a look at four different specialized distributions targeted at the job of an Internet firewall or traffic router. Each one has its own set of features and distinctive, and we'll try to highlight those for you.

The first thing we need to do before we get started is to define what a router is or does. In the most basic sense of the term, a router forwards packets from one network to another. To really understand what's going on you need to picture how Internet traffic moves from one computer to another. If you do a Google search for OSI 7-layer model, you'll find any number of pictures and references describing network traffic as it happens from the lowest layer (physical) up to the highest layer (application). Most routers typically sit at layer 3 since they use an IP address to make decisions on what to do with the data. Most firewalls typically involve the basic functions of a router along with filtering and physical separation, meaning two separate network connections, to do their job.

What happens when a non-coder tries to learn Linux

The Linux Foundation has created all of the content for the course, including the videos, written text, activities, and labs. It's clear to me that their content team has made an effort to space out the videos between the written material in a way that gives you a break from endless reading. Also, each video is only approximately 30 seconds to 2 minutes long. They avoid getting into the weeds too much at once, giving you chunks of knowledge, letting you test it out, then moving on to another topic. Each chapter points out that as the course progresses, you will go into further depth with each topic. Read more

Jailhouse 0.1 released

This release particularly means full exploitation of VT-d DMA and interrupt remapping to isolate assigned PCI devices from the hypervisor and foreign cells. Moreover, the usability of Jailhouse was greatly improved by the introduction and continuous extension of a generator for system configuration files. Finally, a framework for writing basic cell applications is available now. With a few lines of C code you can set up timer interrupts, read clocks or configure PCI devices for the use in simple bare-metal real-time applications. Read more
