Linux Journal's security czar, Mick Bauer, has opined numerous times that a good Netfilter firewall GUI is not just a crutch for the less technical among us, but rather a tool that makes all of us IT administrators work more intelligently. Solsoft recently upgraded its own Netfilter GUI, NetFilterOne. The application is a centralized interface from which one can configure, deploy, enforce and audit rules and policies among Netfilter firewalls. The shiny new Version 1.2 offers the following three key new features: a new Tabular Policy Editor that allows users to manage all permissions in a unified view; bridge mode, also called transparent mode by other providers; and support for Linux Netfilter iptables-1.3.x. A free trial of NetFilterOne is available at Solsoft's Web site.
If your backup duties include files and directories named with non-Latin characters, you're in luck. Arkeia Software's newly released Network Backup Version 5.5 adds full support for Unicode/UTF-8 characters in the backup index. Unicode supports characters from all the world's major languages and is most commonly applied to languages such as Japanese, Chinese and Arabic.
Heroix has upgraded its Longitude agentless performance monitoring and reporting software. The application is intended to monitor an enterprise's entire IT infrastructure, including OS, Web, database, J2EE, messaging, infrastructure, and user and business metrics, all right out of the box and without agent software on monitored computers. Innovations in Version 3 are event correlation across the entire infrastructure, enhanced SLA management via a new graphical event monitor, adjustable workload threshold settings to eliminate false alarms and a range of added monitoring coverage (Cisco devices, Dell OpenManage, HP Systems Insight Manager and SNMP device checking). Platforms monitored are Red Hat and SUSE Linux, Solaris, HP-UX, AIX and Windows. A 14-day free trial is available at Heroix's Web site.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
