The Bullet Points: Linux 2.4

A look at what's new in the next kernel release.
Parallel Ports

Although many users may not notice it, Linux 2.4 includes a complete rewrite of the parallel-port system (again). Like 2.2, Linux 2.4 includes modular support for parallel-port devices including printers and disk drives. Additionally, Linux 2.4 includes “generic” support which would allow for easier support of parallel-port scanners and other devices. Linux 2.4 will also support more parallel ports, including those which require DMA. Many existing systems have this disabled by default in the BIOS; however, it can be reenabled. Also, Linux 2.4 supports using parallel ports as the console. This feature allows some Linux users to use the printer as a debugging tool or keep a hard record of console output.

That's my “Top 8” bullet points of Linux 2.4. Opinions vary greatly as to what features or additions are the most important to each new version of the Linux kernel, and you may have a favorite feature not mentioned here. Linux 2.4 is another great milestone along the path to acceptance and usefulness in a wide variety of markets, and I am positive we will be sharing the “most important features” debate again soon for Linux 2.6. Until then—happy hacking.

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
