  • When I Œrst started using OpenBSD sometime in 1999, it certainly wasn't because I wanted to write a book about it. All I needed was a stable server for my home network, something I could conŒgure and forget about. I tried all obvious suspects: FreeBSD, NetBSD, OpenBSD, and four or Œve different Linux distributions, My choice was OpenBSD, because it installed without problems, was easy to conŒgure, and did not have the infuriating problems with NFS that plagued me on Linux at that time.

  • A networking firewall is a logical barrier designed to prevent unauthorized or unwanted communications between sections of a computer network. Linux-based firewalls besides being highly customizable and versatile are also robust, inexpensive, and reliable. The two things needed to build firewalls and QoS with Linux are two packages named netfilter and iproute. While netfilter is a packet-filtering framework included in the Linux kernels 2.4 and 2.6, iproute is a package containing a few utilities that allow Linux users to do advanced routing and traffic shaping....

This connection may be entirely confined behind a corporate firewall, but more likely includes the public Internet . How are such network connections secured? If they are secured, it is most commonly done by using virtual private networking (VPN) technology from build- ing firewall to building firewall across the Internet .

The name “firewall” comes from the building industry and it denotes a wall constructed to stop (or at least slow) the spread of fire from one space to another. In network security, a firewall serves the same purpose. But instead of being built from bricks or steel it is built with computers and routers. But the concept is still the same. A network firewall is designed to protect what’s “inside” the firewall from what may be “outside.
