Whats New in 4.2 Alpha 1 Development Release:
- ClarkConnect Community 4.2 Alpha 1 is available. Though it has only been four months since the last release, version 4.2 brings quite a few new features. This alpha build is intended for developers, integrators and curious users. Typical uses for this alpha build: final integration testing for third party developers; testing new hardware and drivers with the Linux 2.6.18 kernel; getting a sneak preview of the upcoming 4.2 release. This is alpha software, so quite a few software modules are still incomplete or not well tested. The most important known issues are: Webconfig template graphics and icons are incomplete; graphical console tool does not display on the screen properly....

GNU Parted is a program for creating, resizing, destroying, checking and copying partitions, and the file systems on them. This is useful for creating space for new operating systems, reorganising disk usage, copying data between hard disks and disk imaging.
Supported disk labels: raw access (useful for RAID and LVM), MS-DOS partition tables, Intel GPT partition tables, MIPS partition tables, PC98 partition tables, Sun and BSD disk labels and Macintosh partition maps.
Notes:
- For ext2, ext3 and reiserfs: the start of the partition must stay fixed.
- For ext2, ext3: the partition you copy to must be bigger or exactly the same size as the partition you copy from.
- For ext2 and ext3: the checking is limited to ensuring the resize and copy commands will be ok.
- For fat: the size of the new partition after resizing or copying is restricted by the cluster size. Parted can shrink the cluster size, so you can always shrink your partition. However, if you cant use FAT32 for some reason, you may not be able to grow your partition.
- Parted supports both FAT16 and FAT32. Parted can convert file systems between FAT16 and FAT32, if necessary.
- Reiserfs support is enabled if you install libreiserfs.

Proxmox Mail Gateway project addresses the full spectrum of unwanted e-mail traffic, focusing spam and virus detection.
E-mail security begins at the gateway by controlling all incoming and outgoing e-mail messages. Proxmox Mail Gateway addresses the full spectrum of unwanted e-mail traffic, focusing spam and virus detection.
Proxmox Mail Gateway uses a wide variety of local and network tests to identify spam signatures. This makes it harder for spammers to identify one aspect which they can craft their messages to work around.
Every single e-mail will be analyzed and gets a spam score assigned. The systems attempt to optimize the efficiency of the rules that are run in terms of minimizing the number of false positives and false negatives.
The flexible architecture combined with the easy-to-use configuration interface safeguards companies against existing and new e-mail threats.
Main features:
- Advanced spam detection
- Virus removal including phising e-mails
- Automatic update of virus signature database
- Automatic installation within minutes
- Support for standard PC / Server hardware (i386)
- SCSI and SCSI raid support
- Secure web based configuration
- Object-oriented rulesystem
- Attachment blocking
- Advanced statistics
- Daily reports

sc101-nbd allows Linux to access a Netgear SC101 storage device as a block device, without requiring a new kernel module.
Netgear Storage Central 101 (sc101) is an IP based block storage device.
Netgear ships a clustered filesystem with the product (perhaps based on DataPlow SFS) which allows multiple Windows client machines to concurrently mount and read/write directly to the device; it is a SAN rather than a NAS device.
There is no protocol documentation provided, nor any driver support for operating systems other than Windows.
This software allows Linux to access the the sc101 as a block device, without requiring a new kernel module.
It achieves this by translating between the kernels existing NBD protocol and the reverse engineered protocol used by the sc101 (I call it PSAN, perhaps incorrectly).
On top of the NBD devices you can run RAID, LVM, and any existing filesystems (ext2/3, ocfs2, etc).
The resulting storage area is not interoperable with existing Windows clients.
It is unknown whether this software is compatible with the (unreleased) sc101t or other Zetera partnered devices.
Enhancements:
- This has been tested on RHEL/CentOS 4.x and Ubuntu 7.04.

Rocks Cluster is a complete "cluster on a CD" solution for x86 and IA64 Red Hat Linux COTS clusters.
Building a Rocks cluster does not require any experience in clustering, yet a cluster architect will find a flexible and programmatic way to redesign the entire software stack just below the surface (appropriately hidden from the majority of users).
Although Rocks includes the tools expected from any clustering software stack (PBS, Maui, GM support, Ganglia, etc), it is unique in its simplicity of installation.
From a hardware component and raw processing power perspective, commodity clusters are phenomenal price/performance compute engines. However, if a scalable ``cluster management strategy is not adopted, the favorable economics of clusters are offset by the additional on-going personnel costs involved to ``care and feed for the machine. The complexity of cluster management (e.g., determining if all nodes have a consistent set of software) often overwhelms part-time cluster administrators, who are usually domain application scientists. When this occurs, machine state is forced to either of two extremes: the cluster is not stable due to configuration problems, or software becomes stale, security holes abound, and known software bugs remain unpatched.
While earlier clustering toolkits expend a great deal of effort (i.e., software) to compare configurations of nodes, Rocks makes complete Operating System (OS) installation on a node the basic management tool. With attention to complete automation of this process, it becomes faster to reinstall all nodes to a known configuration than it is to determine if nodes were out of synchronization in the first place. Unlike a users desktop, the OS on a cluster node is considered to be soft state that can be changed and/or updated rapidly.
This is clearly more heavywieght than the philosophy of configuration management tools [Cfengine] that perform exhaustive examination and parity checking of an installed OS. At first glance, it seems wrong to reinstall the OS when a configuration parameter needs to be changed. Indeed, for a single node this might seem too severe. However, this approach scales exceptionally well, making it a preferred mode for even a modest-sized cluster. Because the OS can be installed from scratch in a short period of time, different (and perhaps incompatible) application-specific configurations can easily be installed on nodes. In addition, this structure insures any upgrade will not interfere with actively running jobs.
One of the key ingredients of Rocks is a robust mechanism to produce customized distributions (with security patches pre-applied) that define the complete set of software for a particular node. A cluster may require several node types including compute nodes, frontend nodes file servers, and monitoring nodes. Each of these roles requires a specialized software set. Within a distribution, different node types are defined with a machine specific Red Hat Kickstart file, made from a Rocks Kickstart Graph.
A Kickstart file is a text-based description of all the software packages and software configuration to be deployed on a node. The Rocks Kickstart Graph is an XML-based tree structure used to define RedHat Kickstart files. By using a graph, Rocks can efficiently define node types without duplicating shared components. Similiar to mammalian species sharing 80% of their genes, Rocks node types share much of their software set. The Rocks Kickstart Graph easily defines the differences between node types without duplicating the description of their similarities. See the Bibliography section for papers that describe the design of this structure in more depth.
By leveraging this installation technology, we can abstract out many of the hardware differences and allow the Kickstart process to autodetect the correct hardware modules to load (e.g., disk subsystem type: SCSI, IDE, integrated RAID adapter; Ethernet interfaces; and high-speed network interfaces). Further, we benefit from the robust and rich support that commercial Linux distributions must have to be viable in todays rapidly advancing marketplace.
Wherever possible, Rocks uses automatic methods to determine configuration differences. Yet, because clusters are unified machines, there are a few services that require ``global knowledge of the machine -- e.g., a listing of all compute nodes for the hosts database and queuing system. Rocks uses an SQL database to store the definitions of these global configurations and then generates database reports to create service-specific configuration files (e.g., DHCP configuration file, /etc/hosts, and PBS nodes file).
Enhancements:
- Rocks v4.3 is released for i386 and x86_64 CPU architectures. New features: Rocks command line - initial release of the Rocks command line which facilitates non-SQL administrative access to the database; PXE First - hosts can now be configured in BIOS with a boot order of CD, PXE, hard disk. Enhancements: based on CentOS 4.5 and all updates as of July 4, 2007; Anaconda installer updated to 10.1.1.63; performance improvement when building torrent files for the Avalanche Installer; database indirects, more flexibility with Rocks variables; Globus updated to gt4.0.4 with web services....

DKP Log Parser (DKPLP) is a tool designed to help administrate time-based and/or event-based DKP reward system in conjunction with EQDKP (or any other DKP software implementing a required interface). The project is configurable to be compatible with any game that produces any kind of log. There are currently predefined pattern sets for EverQuest, EverQuest2 and World of Warcraft (with CT RaidTracker). If you are playing another game then you can either write new patterns for it yourself, or ask the the forum (be sure to include a sample log though).
DKP Log Parsers goal is to reduce the administrative overhead of running complex DKP reward system, by parsing the logs, calculating the DKP per person and sending the results (the loot, raids, participants and DKP) directly to EQDKP (or other DKP software). Its widely configurable, allowing it to be used by the many variations of zero-sum and time-based DKP around.
Overview of how DKP Log Parser is used
DKP Log Parser is a software program run on a users desktop (Windows or Unix). It reads in the contents of a game log once a raid has been completed, parses all the information and displays the data for administrators to edit. Once happy with the information, the administrator uploads the data from their PC to the DKP Log Parser plugin on an EQDKP webserver (or any other server implementing the required DKPLP interface), where it can be viewed by all members of the DKP system.
Main features:
- Inbuilt support for Everquest, Everquest II, World of Warcrafts CT RaidTracker plugin, and Ventrilo.
- Extensible enough to be able to handle most logs.
- Time based dkp:
- Accrue DKP by minute, by interval, by event or by a combination of these.
- Zero-sum DKP can be enabled (by minute or by interval) or disabled.
- Tag certain intervals as being more or less important by using weightings to adjust the DKP.
- Data export:
- Upload data to for example EQDKP, select from a number of different data representations.
- Export to plain text
- Export to BB forum markup
- Export to wiki markup
- Export to XML
- Member list and alt character list synchronises with server, making it easy to share setups with other users.
- Optional autocompletion database to remember item names and values between sessions.
- Preprocessors available to perform other operations on the log file. The skys the limit!
