Improving Linux Internet Access Using Mobile IPv6 Technology

The woman who cut me off on the freeway because she was too busy talking on her cell phone might not have had a clue, but she probably had an IP address. Mobile devices, from cell phones to PDAs to the automobiles themselves, increasingly require always-on Internet connectivity. According to at least one report, the average U.S. home has over 250 devices that could benefit from Internet connectivity. While the number of IP addresses in the world is large -- IPv4's 32-bit addressing scheme enables 4 billion addresses -- it is not infinite. And the woman applying blue eyeshadow on the 101 freeway is using up one of them. . You may have heard this argument for IPv6 before: that the Internet needs to expand to IPv6 (128-bit addresses, enabling enough addresses for every grain of sand on the planet). There are plenty of other advantages to the IPv6 protocol, however, which often get shunted down to the last paragraph or two in an article. The link for this article located at AlwaysOn-Network is no longer available. . Mobile IPv6 on Linux revolutionizes networking, allowing effortless mobility for users across networks while maintaining IP addresses and services..

Novell Sponsors Openswan Project for Secure IPsec VPN Standards

Novell announced that it is sponsoring and contributing to the popular open source Linux implementation of the IP security (IPsec) standard development project, Openswan.

Novell announced that it is sponsoring and contributing to the popular open source Linux implementation of the IP security (IPsec) standard development project, Openswan. The open source project brings all of the features needed for building and deploying secure commercial grade virtual private networks (VPNs) to Linux. Secure VPNs are increasingly being deployed in the enterprise to provide a high level of security. IPsec is standardized protocol from the Internet Engineering Task Force (IETF) that provides a standard way of transmitting services which allow users to build secure tunnels through untrusted networks. Information is encrypted by the IPsec gateway machine and decrypted on the other end. IPsec-certified products are interoperable across vendor product lines, and provide security. Salt Lake City-based Novell also announced today that its BorderManager product is certified on the latest IPsec interoperability tests from ICSA Labs. This testing demonstrates interoperability and open standards compliance. Novell's BorderManager is part of the company's Nsure secure identity management solution.

IPv6 Design Improvements: Enhancing Linux Networking Performance

IPv6 is the next-generation Internet protocol designed by the IETF as a replacement for IPv4. Most of today's Internet uses IPv4, which has been remarkably resilient in spite of its age; however, it is beginning to have problems in various features areas. . . .. IPv6 is the next-generation Internet protocol designed by the IETF as a replacement for IPv4. Most of today's Internet uses IPv4, which has been remarkably resilient in spite of its age; however, it is beginning to have problems in various features areas. Its most visible shortcoming is the growing shortage of IPv4 addresses needed by all the new devices connecting to the Internet. Other limitations are in such areas as QoS, security, autoconfiguration, and mobility. As a result, the IETF defined IPv6 to fix the problems in IPv4, and added many enhancements to cater the future Internet. This article addresses the problems in IPv4 that lead to the design of IPv6, presenting the IPv6 design philosophies and IPv6 features, as well as a technical tutorial to enable IPv6 support on your Linux machines.

Debian Firewall Configuration: IP Masquerading for Safe Internet Sharing

John Gowin wrote in about using IP masquerading and Debian to build a simple firewall. "This tutorial will give you the necessary steps to turn one of your old PCs into a firewall with IP Masquerading, using a popular Linux distribution. I will leave it to you to get and install Debian onto your machine and work out connectivity to your ISP, then I will guide you through a kernel compile and install. . ..

I will leave it to you to get and install Debian onto your machine and work out connectivity to your ISP, then I will guide you through a kernel compile and install - which is necessary to enable features in the 2.4.x series kernels which allow your Linux machine to act as a firewall. IP Masquerading is a type of network address translation (NAT) in the Linux kernel which allows packets (chunks of formatted data) from an internal machine to appear to be coming from the public interface of the firewall. This allows machines on the local network to assume the address of the firewall when communicating on the internet, thereby making them "hidden" from attackers."

Linux Packet Filter Insights: Network Processing and Socket Analysis

In Part I of this two-part series on the Linux Packet Filter, Gianluca describes a packet's journey through the kernel. Network geeks among you may remember my article, ``Linux Socket Filter: Sniffing Bytes over the Network'', in the June 2001 issue of LJ, regarding the use of the packet filter built inside the Linux kernel.. . .. In Part I of this two-part series on the Linux Packet Filter, Gianluca describes a packet's journey through the kernel. Network geeks among you may remember my article, ``Linux Socket Filter: Sniffing Bytes over the Network', in the June 2001 issue of LJ, regarding the use of the packet filter built inside the Linux kernel. In that article I provided an overview of the functionality of the packet filter itself; this time, I delve into the depths of the kernel mechanisms that allow the filter to work and share some insights on Linux packet processing internals. Now we are going to follow the trip of a packet from its very ingress into the computer to its delivery to user land at the socket level. We first consider the general case of a plain (i.e., not PF_PACKET) socket. Our analysis at link layer level is based on Ethernet, since this is the most widespread and representative LAN technology. Cases of other link layer technologies do not present significant differences. The link for this article located at Linux Journal is no longer available. .
