RHEL 5.7 adds OpenSCAP

With all the excitement around Red Hat Enterprise Linux 6.1 last week, it's important to remember that most RHEL users are still likely on RHEL 5. RHEL 5 debuted in March of 2007 and has been updated with 6 incremental updates over the last four years. The last major update, RHEL 5.6 came out in January of 2011. With RHEL 6.x now in market, I would have guessed that RHEL 5 at this point would be just about bug, stability and driver updates, but that's not the case. Red Hat is still adding FEATURES to this distro. In RHEL 5.7, which is now in Beta, Red Hat is adding support for OpenSCAP which is a big win for security. OpenSCAP is an open source implementation of the Security Content Automation Protocol (SCAP) framework for creating a standardized approach for maintaining secure systems. Red Hat's Fedora community Linux distro has included OpenSCAP since the Fedora 14 release in October of 2010. Typically it takes longer for a Fedora technology to land in RHEL, but OpenSCAP is just one of those things that makes so much sense (and clearly is already enterprise ready) that Red Hat is electing to get it into RHEL now -- at least in beta. RHEL 5.7 also provides improved capabilities for the Xen Hypervisor, which is not something that Red Hat has continued into RHEL 6.  

According to the release notes for RHEL 5.7:

• The performance of Xen guests in 32-bit domains is improved.
• The maximum amount of disks that can be attached to a Xen guest has been increased from 100 to 256.
• The time needed to boot Xen guests is reduced.
• Xen guests now support up to 4 serial ports.
• xz compression support is now available in Xen pygrub.

All good news for RHEL 5.x users that intend for whatever reason  to stick with the platform instead of moving to RHEL 6. That's not to say that RHEL 6.x isn't more robust overall, but hey big mission critical systems aren't things that are easily migrated from one version to another.

Linux Kernel 3.0

Last week began with speculation about a new kernel version number that ultimately resulted in the first big number change for Linux in more than a decade. Along the way, we also saw new Linux distribution releases, including Fedora 15 and the first beta of Red Hat Enterprise Linux 5.7.

1. Linux 3.0

Make no mistake about it, after two decades of being the leader of the Linux community, Linus Torvalds still makes the big decisions.

This week, Torvalds made the huge decision of starting a new numbered version of Linux, advancing the kernel to Linux 3.0, with a first release candidate debuting early Sunday. The Linux 3.0 kernel came after a week of discussion, which began with Torvalds first mentioning that he was considering advancing the number to Linux 2.8, instead of having a Linux 2.6.40 kernel release. "The voices in my head also tell me that the numbers are getting too big," Torvalds wrote in a mailing list posting. By the end of the week, Torvalds was advocating for a 3.0 release, as Linux is now entering its third decade. While big number version changes can often represent binary compatibility or big feature change issue with a software project, that's not the case with Linux 3.0. The 3.0 nameplate is a time-based thing, and it isn't about new features. Considering Linux 2.0 came out in 1996 and the more recent 2.6 branch began in 2003, the big number change is a long time coming for Linux. While some software projects, like Google's Chrome, change major version numbers every three months, Linux has iterated on the 2.6.x branch for more than seven years. The change to 3.0 may seem a bit arbitrary, but it makes sense on many levels. The time has come for a number change as Linux enters its third decade.

2. Fedora 15

This past week also marked the debut of Fedora 15, codenamed 'Lovelock.' While Linux 3.0 isn't about new features, Fedora 15 is about features, most notably the GNOME 3.0 desktop. Fedora 15 is the first of the big Linux distributions to integrate GNOME 3 and its associated GNOME Shell user interface. Fedora 15's GNOME 3 desktop stands in contrast to the Unity desktop that rival distribution Ubuntu debuted in April. While Fedora is a big backer of GNOME Shell, the project also realizes it's not for everyone and includes fallback mechanisms for older hardware as well as other desktop options, including KDE, Xfce and LXDE. Time will tell whether users prefer GNOME Shell to Unity or if they end up rejecting both desktops in favor of something else.

3. Linux Mint 11

For Ubuntu users that don't want Unity and don't want to move to Fedora (or something else), there is Linux Mint. Over the past couple of years, Mint has emerged as a community favorite alternative to Ubuntu. Based on Ubuntu, Mint takes the best of Ubuntu and aims to make it even easier to use. For GNOME users, Mint has elected not to use either GNOME shell or Unity, providing users with a more traditional user interface. Given the backlash in some corners against Unity on Ubuntu, it's likely that Linux Mint 11 will attract more than its fair share of Ubuntu 11.04 refugees. Will those former Ubuntu users stick with Mint over time? Considering Mint is based on Ubuntu, that's a bet that doesn't carry too much risk.

4. Red Hat Enterprise Linux 5.7

No, it's not a major new version number of Red Hat's Enterprise Linux (RHEL), but RHEL 5.7 is still an important release. This past week, Red Hat released the first beta of RHEL 5.7 with new driver and stability updates. RHEL 5.0 first came out in 2007 and has since been superseded by RHEL 6, which came out at the end of 2010. There is a class of users that don't magically switch overnight to major new releases (if ever) and that's why RHEL 5.7 is important. Looking beyond the usual set of driver updates, Red Hat (NYSE: RHT) also packed in at least one new feature too. RHEL 5.7 supports OpenSCAP, which is an open source implementation of the Security Content Automation Protocol (SCAP) framework for creating a standardized approach for maintaining secure systems. While RHEL 5.7 isn't a major new release, for Red Hat's RHEL 5 customer base, it's a solid update that will refresh their installed servers.

5. Puppy Linux

Linux users come in all shapes and sizes. While big vendors like Red Hat target mission-critical enterprise systems, other distros, like Puppy Linux, serve a different audience. Wary Puppy Linux is a minimal Linux distributions that requires less hardware resources than other distros. This makes it ideal for older hardware that other distros (and any other OS) would deem to be obsolete. This past week Wary Puppy Linux 5.1.2 was released with the promise of even better support for older hardware.

Red Hat Inc Announced The General Availability Red Hat Enterprise Linux (RHEL) 6.5

Red Hat Inc Announced The General Availability Red Hat Enterprise Linux (RHEL) 6.5 

The RHEL 6x series get another important update as Red Hat Inc, the world's leading provider of open source solutions announced the general availability of Red Hat Enterprise Linux 6.5, the latest version of Red Hat Enterprise Linux 6. According to the official press release of Red Hat -RHEL 6.5 expands Red Hat’s vision of providing an enterprise platform that has the stability to free IT to take on major infrastructure challenges and the flexibility to handle future requirements, with an extensive partner and support ecosystem. 

Red Hat Enterprise Linux 6.5 is mainly designed for those who build and manage large, complex IT projects, especially enterprises that require an open hybrid cloud. From security and networking to virtualization, Red Hat Enterprise Linux 6.5 provides the capabilities needed to manage these environments, such as tools that aid in quickly tuning the system to run SAP applications based on published best practices from SAP.“Red Hat Enterprise Linux 6.5 provides the innovation expected from the industry’s leading enterprise Linux operating system while also delivering a mature platform for business operations, be it standardizing operating environments or supporting critical applications. The newest version of Red Hat Enterprise Linux 6 forms the building blocks of the entire Red Hat portfolio, including OpenShift and OpenStack, making it a perfect foundation for enterprises looking to explore the open hybrid cloud.”-said Jim Totton, vice president and general manager of Red Hat Inc. Now lets take a closer look to the main highlights of RHEL 6.5 : 

Securing the Next-Generation Enterprise

Red Hat Enterprise Linux 6.5 continues the push for integrated security functionality that combines ease-of-use and up-to-date security standards into the platform. The addition of a centralized certificate trust store enables standardized certificate access for security services. Also included are tools that meet leading security standards, including OpenSCAP 2.1, which implements the National Institute of Standards and Technology’s (NIST’s) Security Content Automation Protocol (SCAP) 1.2 standard. With these additions, Red Hat Enterprise Linux 6 provides a secure platform upon which to build mission-critical services and applications.

Networking – When Every (Micro)Second Matters

In the financial services and trading-related industries, application latency is measured in microseconds, not seconds. Now, the latest version of Red Hat Enterprise Linux 6 fully supports sub-microsecond clock accuracy over the local area network (LAN) using the Precision Time Protocol (PTP). Precision time synchronization is a key enabler for delivering better performance for high-speed, low latency applications. Red Hat Enterprise Linux 6.5 can now be used to track time on trading transactions, improving time stamp accuracy on archived data or precisely synchronizing time locally or globally. Thanks to other networking enhancements in Red Hat Enterprise Linux 6.5, system administrators now have a more comprehensive view of network activity. These new capabilities enable sysadmins to inspect IGMP (Internet Group Management Protocol) data to list multicast router ports, multicast groups with active subscribers and their associated interfaces, all of which are important to many modern networking scenarios, including streaming media.

Virtualization Enhancements

Red Hat Enterprise Linux 6.5 continues Red Hat’s commitment to improving the overall virtualization experience and includes several improvements that make it a compelling choice for running in virtualized environments. Sysadmins can now dynamically enable or disable virtual processors (vCPUs) in active guests, making it an ideal choice for elastic workloads. The handling of memory intensive applications as Red Hat Enterprise Linux guests has also been improved, with configurations supported for up to 4TB of memory on the Kernel-based Virtual Machine (KVM) hypervisor. The KVM hypervisor also integrates with GlusterFS volumes to provide direct access to the distributed storage platform, improving performance when accessing Red Hat Storage or GlusterFS volumes. Finally, guest drivers have been updated to improve performance of Red Hat Enterprise Linux 6.5 running as a guest on supported third-party hypervisors.

Evolving Ease-of-Use, Storage, and More

As application deployment options grow, portability becomes increasingly important. Red Hat Enterprise Linux 6.5 enables customers to deploy application images in containers created using Docker in their environment of choice: physical, virtual, or cloud. Docker is an open source project to package and run lightweight, self-sufficient containers; containers save developers time by eliminating integration and infrastructure design tasks. Red Hat Enterprise Linux 6.5 stays current with the advancements in Solid-State Drive (SSD) controller interface, introducing support for NVM Express (NVMe)-based SSDs. The NVMe specification aims to standardize the interface for PCIe-based SSDs and its inclusion in Red Hat Enterprise Linux 6.5 positions the platform to support an expanding range of future NVMe-based devices.

Improvements have also been added to improve enterprise storage scalability within Red Hat Enterprise Linux 6.5. It is now possible to configure more than 255 LUNs connected to a single iSCSI target. In addition, control and recovery from SAN for iSCSI and Fibre Channel has been enhanced, and updates to the kexec/kdump mechanism now make it possible to create debug (dump) files on systems configured with very large memory (e.g. 6TB).

Red Hat Enterprise Linux 6.5 makes it easier to track and manage subscription consumption across the enterprise, integrating subscription tracking into existing business workflow. Usability enhancements include support for remote access to Windows clients and servers that use a newer version of the RDP protocol, including Windows 7 and 8 desktops and Windows Server 2012.

CentOS 6 is Now Available

Seven months after the release of Red Hat Enterprise Linux (RHEL) 6.0, the CentOS developers have announced the release of CentOS 6.0. The RHEL 6.0 clone is currently only available as a DVD image for x86-32 and x86-64 systems; however, Live CDs are reportedly in preparation and the developers have also said that they plan to issue a "Minimal Install CD" in the coming days. They also intend to provide information on a "LightWeightServer (LWS) CD" that, similar to the "CentOS 4 Server CD", will contain the key components to set up a server.

Updating from CentOS 4 or 5 to version 6 is not recommended. Until the release of CentOS 6.1, the project plans to provide the security updates Red Hat integrated into RHEL 6.1, as well as those that have been issued since its release, via a "continuous release repository"; further details are to follow within 48 hours of the release of CentOS 6.

CentOS 6.0 is the last of the three most popular distributions whose developers take the RHEL source packages, substitute the protected components (for example, the Red Hat logos), and after recompiling assemble the whole thing into a distribution that is said to be fully compatible with the original. Oracle released its Oracle Linux 6.0 in February, and the Scientific Linux (SL) project released its identically named clone in March. In mid-May, Red Hat released the first minor update to RHEL6, version 6.1. Oracle released a clone of this version in early June; the Scientific Linux developers are still working on theirs. The CentOS developers have not indicated a release date for CentOS 6.1.

Red Hat Enterprise Linux (RHEL) 6.3 Released & Globally Available

Red Hat Enterprise Linux (RHEL) 6.3 Released & Globally Available

Only six months after the release of RHEL 6.2. Red Hat officially announced the global availability of the next minor release of Red Hat Enterprise Linux operating system platform, Red Hat Enterprise Linux 6.3. Couple of months ago we got the Beta of RHEL 6.3 and with this final release Red Hat has tweaked the enterprise grade Linux distribution to add new capabilities in storage, virtualization, security, developer tools, file systems, scalability and performance.

Highlighted Features :-

• Developer Tools: In addition to OpenJDK6 support in Red Hat Enterprise Linux 6, the newly introduced OpenJDK7 allows customers running Red Hat Enterprise Linux 6.3 to develop and test with the latest version of open source Java. The Red Hat Developer Day is scheduled for June 26th at the 2012 Red Hat Summit & JBoss World. More about this and other capabilities will be presented, including the Red Hat Enterprise Linux toolset (updated GCC), performance optimization, thread programming and NUMA. For more information about developer day, please visit here.

• Virtualization: Red Hat Enterprise Linux 6.3 helps smooth migration to a virtualized environment. This is achieved with the help of new Virt-P2V tools that can easily convert a Red Hat Enterprise Linux or Microsoft Windows system running on physical hardware to run as KVM guests. This release implements a more robust mechanism to protect data associated with defunct virtual machines. The method by which virtual disk images are securely wiped has been enhanced to allow greater security and stronger compliance with Payment Card Industry Data Security Standards (PCI-DSS).

• Security: Users can now use two-factor authentication for securely accessing their Red Hat Enterprise Linux environment. This type of authentication mechanism is more secure than simple password based authentication. Two-factor authentication is being adopted into enterprise environments and is often referenced in industry standards. Red Hat Enterprise Linux 6.3 also includes advanced encryption capabilities so data blocks can be encrypted in parallel by taking advantage of underlying multi-processor capabilities. This is supported by the introduction of AES-CTR (Advanced Encryption Standard Counter Mode) cipher for OpenSSH. AES-CTR is well suited for high-speed networking environments.

• Scalability: Red Hat Enterprise Linux 6.3 continues to test the outer bounds of scalability for an operating system platform by increasing the maximum number of virtual CPUs (vCPUs) per guest to 160 from 64. This is significantly higher than the 32 vCPU per guest limit for VMware ESX 5.0. The maximum supported memory configuration for KVM guests has also been increased from 512GB to 2TB.

• File Systems: File system improvements include O_DIRECT support in FUSE (File system in user space). When enabled, all FUSE reads and writes go directly to storage, bypassing the server cache. This capability can lead to more consistent response times and predictable access to data by multiple accessors for certain use-cases, including database writes and deduplication. GFS2 (shared storage file system) can now read and write data to the disks faster than in previous releases for certain use-cases. In addition, file system check utilities for GFS2 can now be used to check the integrity of the older GFS1 file system.

• Storage: The Logical Volume Manager (LVM) now provides support for RAID levels 4, 5, and 6 to simplify overall storage administration by consolidating all management functions, such as creating and re-sizing volumes, deploying RAID, and taking snapshots into a single interface. It is now possible to deploy Red Hat Enterprise Linux 6 as a FCoE based storage target server providing the high level of reliability and performance available with native Fibre Channel but at a significantly lower cost. This feature complements the FCoE Initiator support that was delivered in Red Hat Enterprise Linux 6.0.

• Subscription Management: With Red Hat Enterprise Linux 6.3, by default customers can use Red Hat Subscription Management (SAM), an enhanced subscription management capability using X.509 certificates that allows customers to effectively manage subscriptions locally and report on subscription distribution and utilization. This helps facilitate compliance, upgrades, and long-term planning. Customers register their systems using Red Hat Subscription Manager to the Red Hat award-winning customer portal or an instance of Red Hat Enterprise Linux SAM. Customers who used RHN Classic subscription management with prior releases of Red Hat Enterprise Linux, can continue to use it or migrate to Red Hat Subscription Management.

Red Hat Announced Beta of Red Hat Enterprise Linux (RHEL) 6.3

Red Hat Announced Beta of Red Hat Enterprise Linux 6.3

Just over four months after the release of Red Hat Enterprise Linux (RHEL) 6.2, developer at RedHat has made a beta of version of RHEL 6.3 available. This beta includes a broad set of updates to the existing feature set and also provides rich new functionality particularly in the areas of virtualization, scalability, storage, file systems, and security. As always, the Red Hat Enterprise Linux 6.3 beta delivers new hardware enablement made possible by our strong relationships with our strategic hardware partners. This beta release has been designed for optimized performance, scalability, and reliability to cater to the diverse workloads running in physical, virtual and cloud environments.

Key Features in the Red Hat Enterprise Linux 6.3 Beta:-

Virtualization-

• A new tool called Virt-P2V that facilitates the conversion of physical Windows or Red Hat Enterprise Linux systems into virtual images to be deployed as KVM guests inside Red Hat Enterprise Linux or Red Hat Enterprise Virtualization.

• Stronger compliance with Payment Card Industry Data Security Standards (PCI-DSS), including the ability to perform secure wipes of virtual machine disks.

• The ability to perform live volume resizing, improving the overall availability of virtualized guests.

Scalability-

• The maximum number of virtual CPUs (vCPUs) has been increased from 64 to 160, which lets you run larger CPU-intensive workloads on the Red Hat Enterprise Linux platform. VMware ESX 5.0 currently support 32 vCPUs.

• The maximum supported memory configuration for KVM guests has been increased from 512GB to 2TB.

File Systems-

• GFS2 enhancements that create faster read-write capabilities for specific use cases.

• Support of O_Direct in FUSE (Filesystem in User Space), which can provide improved performance for certain workloads.

• Simplified configuration and administration for the file system. Integration of automount capability with System Security Services Daemon (SSSD) provides centralized management of configuration data and the ability to improve performance through caching and load balancing. (This feature is a Technology Preview.)

Storage-

• Red Hat Enterprise Linux 6.3 provides full support for Fibre Channel over Ethernet (FCoE) Target. This feature, which was previously provided as a Technology Preview, allows customers to present their Red Hat Enterprise Linux servers as FCoE storage devices. This feature complements the FCoE Initiator support that was delivered in Red Hat Enterprise Linux 6.0.

• The Logical Volume Manager (LVM) now provides support for RAID levels 4, 5, and 6. (Previously, support for these RAID levels was provided through the MD subsystem.) This expanded LVM RAID support simplifies overall storage administration by consolidating all management functions, such as creating volumes, resizing volumes, deploying RAID, taking snapshots, etc., into a single interface. (This feature is a Technology Preview.)

• The LVM now provides the ability to create thin provisioned logical volumes. Previously, storage was allocated when the volume was created, and needed to be monitored for space consumption and expanded manually. In Red Hat Enterprise Linux 6.3, storage is allocated as required, allowing volumes to expand up to the requested size on demand without intervention. (This feature is a Technology Preview.)

Security-

• Availability of a two-factor authentication mechanism, enhancing the overall security available to lock down Red Hat Enterprise Linux environments and enabling compliance with industry standards such as PCI-DSS.

• Expansion of the Advanced Encryption Standard (AES) to provide particular benefits for system performance on multi-processor machines.

Identity Management-

• With native support for netgroups and the services map in System Security Services Daemon (SSSD), Red Hat Enterprise Linux servers can be integrated into centralized systems -- such as Active Directory -- to manage system users.

• The addition of an automembership plug-in streamlines the administration of new users and hosts when they are added into the Identity Management system by automatically placing them into a predefined set of groups, speeding user and host provisioning.

• Performance improvements through session data caching, which lowers the overall load on authentication servers.

Hardware Enablement-

• Software bandwidth management for USB 3.0 for select Intel platforms is now available.

• Compiler optimization for Intel Xeon E5 processor family, which improves the result of string operations, is now included.

• Improvements to memory and I/O breakpoint execution operations within compiler tools are now included.

Developer Tools-

• With the introduction of OpenJDK 7, customers can develop and test with the latest version of open source Java.

Red Hat Enterprise Linux (RHEL) 6.2 Released

After RHEL 6.2 Beta now Red Hat the world’s leading provider of open source solutions, today announced the general availability of Red Hat Enterprise Linux 6.2. With this milestone, Red Hat includes many enhancements that deliver benefits spanning multiple areas, including performance and scalability. Red Hat Enterprise Linux 6 operating system achieved the largest multi-core Linux configuration results certified to-date on the two-tier SAP® Sales and Distribution (SD) standard application benchmark.1 Proven to perform and scale, Red Hat Enterprise Linux 6 effectively supports large, mission-critical enterprise computing environments.

Vice President and General Manager, Platform Business Unit at Red Hat, said, “The exciting features in Red Hat Enterprise Linux 6.2 with new impressive SAP® benchmark results allow our enterprise customers to have increased confidence that Red Hat Enterprise Linux 6 can run their enterprise workloads with high performance across physical, virtual and cloud computing environments.”

Enterprises can confidently migrate to the latest multi-core technology with Red Hat Enterprise Linux 6. On the latest two-tier SAP SD standard application benchmark, Red Hat Enterprise Linux 6 achieved more than 22,000 SAP SD benchmark users on a single system. On this same benchmark, the HP DL980 G7 system running Red Hat Enterprise Linux 6 fully utilized all 80 cores and 160 threads in the 8-processor system running MaxDB 7.8 and the SAP enhancement package 4 for the SAP ERP 6.0 application. This is the largest Linux result submitted to SAP to-date. The results demonstrate the capabilities of the HP ProLiant DL980 G7 8-processor system’s PREMA architecture and smart CPU caching technology. Results are as of December 2, 2011, certification number 2011052.

“Clients need solutions to automate, scale-up or virtualize their environments to best fit their business requirements,” said Martin Whittaker, vice president, Systems and Solutions Engineering, Enterprise Servers, Storage and Networking at HP. “Optimizing Red Hat Enterprise Linux on HP ProLiant DL980 systems extends the power of open source to HP Converged Infrastructure, delivering uptime, increased capacity and faster processing speeds.”

Red Hat Enterprise Linux 6.2 delivers significant improvements in resource management and high availability, as well as new features aimed at storage and file system performance and identity management. Red Hat Enterprise Linux 6.2 provides additional capabilities to manage system resources. For service providers or internal IT organizations that deliver applications or hosted services via multi-tenant environments, maximums can be set for CPU time associated with a given application, business process or a virtual machine. This allows for more efficient management of SLAs and enables the ability to implement service priorities, similar to those associated with network Quality of Service (QoS).

When an enterprise deploys its applications to run in a Red Hat Enterprise Linux 6.2 guest hosted by VMware, the applications can now be utilized for High Availability (HA) Add-Ons. This also includes full support for use of GFS2 shared storage file system by the virtual machines. The result is additional deployment flexibility for customers requiring HA within a portion of their virtualized environment, as well as full support for Red Hat Enterprise Linux on the VMware hypervisor.

Red Hat Enterprise Linux 6.2 adds enhancements to storage and file system features including full support of iSCSI extension for RDMA. Now, benefits of low latency and high throughput through a standard SAN implementation based on 10Gb Ethernet are available to even the most demanding storage environments. This allows customers to opt out of expensive Infiniband hardware or other dedicated interconnect fabrics. Other enhancements around file system include delayed meta data logging, asynchronous and parallel file system writes, as well as support for multiple active instances of Samba in a cluster which improves overall throughput and increases availability for large Samba clustered deployments.

Identity Management:-

In Red Hat Enterprise Linux 6.2 provides the administrative tools to quickly install, configure and manage server authentication and authorization in Linux/Unix enterprise environments, while still providing the option to interoperate with Microsoft Active Directory. This enables enterprises to manage Linux infrastructure easily and cost-effectively. Centralized identity management and host-based access control can reduce administrative overhead, streamlines provisioning and improves security.

Performance:- 

Is key to all customers. Red Hat Enterprise Linux 6.2 continues to put an emphasis on accelerating I/O such as network traffic steering to improve network throughput by as much as 30 percent in performance tests conducted by Red Hat and delivering numerous file system enhancements that reduce read-write times and boost overall system utilization.

Red Hat expects to deliver the beta for Red Hat Enterprise Linux 5.8 later this month. Also fully underway is development for Red Hat Enterprise Linux 7, the next major release of Red Hat Enterprise Linux. Red Hat received an outstanding response from all Red Hat subscribers – users and partners – for requested features coming from the recent Red Hat Enterprise Linux 7 Ideas discussion group posted on the Red Hat customer portal. This important feedback allows Red Hat to continue to make Red Hat Enterprise Linux a computing foundation for the next generation of operating system platforms.

Z-Admin (New GUI Admin For Zarafa)

                                    

Zarafa has released version 1.0 of Z-Admin, the company's next generation, its an open source administration interface for the Zarafa Collaboration Platform (ZCP). With the Z-Admin web application, system administrators can set up, configure, monitor and maintain a Zarafa mail server using any modern browser. To develop Z-Admin, Zarafa worked with German firm bitbone to integrate the open source Yaffas (Yet another framework for administering servers) administration framework into the groupware server.As can be expected, the tool's main administrative focus is on the mail server area. From basic mail server settings to spam filter rules, system administrators can now do their work using the Z-Admin GUI. Admins can also check memory consumption and cache settings at runtime, and optimise them if required. For editing and managing users and groups, Z-Admin can – depending on the requirements – either use the ZCP server's data or access an external OpenLDAP or Active Directory server.

Licensed under the AGPLv3, Z-Admin 1.0 is available to download from the company's site, and is compatible with Red Hat Enterprise Linux (RHEL) and Ubuntu Server.

Fedora 15 beta released as GNOME 3 backlash grows

The Fedora Project announced the beta release of Fedora 15 "Lovelock," featuring the new GNOME 3 desktop, the Systemd initialization system, and a new dynamic firewall feature. Meanwhile, GNOME 3 has received mixed reviews, with many claiming the project went too far in simplifying the interface.

The new beta version of Fedora 15 follows an alpha that arrived in early March. The final is expected in late May. Sponsored by Red Hat, the community-based Fedora is aligned with the commercial Red Hat Enterprise Linux (RHEL) release, with Fedora largely used as an upstream, exploratory sandbox for Red Hat.

The "Lovelock" release of Fedora offers a variety of additions and enhancements for the desktop and server, led by the GNOME project's GNOME 3 desktop, which formally debuted earlier this month (see farther below). Other changes include new KDE 4.6 and Xfce 4.8 desktops, and a cloud-oriented BoxGrinder appliance builder.

There's also the new OpenOffice.org clone LibreOffice 3.3, which was developed as a fork project after users began worrying about Oracle's commercial ambitions for OpenOffice. Last week Oracle released OpenOffice.org as a fully open source community project, while halting sales of its commercial version, but momentum seems to have already shifted to LibreOffice -- which added several new features in its debut release while stripping out others.

Fedora 15 also features Systemd as the default configuration utility, replacing SysVinit and Upstart for system and session management. The most noticeable change is a faster boot experience, says the project.

For the beta announcement, the project calls out the dynamic firewall feature as a highlight, suggesting it is more complete in this beta version. The firewall lets users change settings without the need to restart the firewall, says the project. The firewall is also said to make persistent connections possible.

For more details on Fedora 15, please see our previous Fedora 15 alpha coverage, as well as the links at the end of the story.

GNOME 3: Too dumbed down for Linux users?

GNOME 3, which will first appear in Fedora 15 as the default desktop, and in Ubuntu 11.04 as the newly demoted backup to Canonical's Unity desktop, was announced earlier this month with much fanfare. Among many other changes, GNOME 3.0 features a new, streamlined GNOME Shell and desktop, as well as improvements to search, user messaging, system settings, and the GTK+ libraries, plus a major revision of the Nautilus file manager.

Years in the making, the release was intended as a consumer-oriented refresh for a desktop environment that has increasingly been perceived by newcomers as confusing and overly technical compared to KDE and other desktop environments.

Yet according to many GNOME users, the project may have gone too far in simplifying the interface. 

As summed up in a recent LinuxInsider story by Katherine Noyes, Linux bloggers and forum posters have beenventing over all the changes in the last two weeks. While mainstream reviews have been largely favorable, Noyes reports on a sizable backlash among GNOME users who say the environment has gone too far in the direction of minimalism.
