Apache Talking IPv6

A technical tutorial on setting up Apache to serve HTTP requests over IPv6 and some preliminary benchmarking results.
Conclusion

IPv6 is becoming a reality. For the next few years, we need to be able to support both IPv4 and IPv6 on our application servers before the complete transition to IPv6 occurs. The developers of Apache are aware of this, and they have already built in support for IPv6 in the Apache code. Previously, the support for IPv6 was in the form of a downloadable patch (from the Kame Project, for instance) that you would apply to the source tree.

As the benchmarking results suggest, serving documents over IPv6 is slightly slower (in terms of requests/second) than serving them over IPv4; however, this is understandable because the IPv6 support is still in its early stages. As the development advances, Apache is expected to reach and exceed the level of performance it achieved with IPv4 to remain the preferred web server in the world.

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.
