GTP server simulator is a simple responder for the GTP (GTP prime) protocol that works with the Cisco Content Services Gateway to provide per-user traffic limits.

GTP` (GTP prime) server simulator (it permits any content and provide quadrants for every operation) binaries for Linux (run under Fedora Core 4 and 5).

The binary was tested with Cisco CSG.

Enomalism Virtualized Management Console project is a open source web-based systems administrator management tool for XEN hypervisor. Servers with hundreds of multiple isolated virtualized systems can be managed like a standalone server.
Enomalism also includes a virtual server creation wizard and templates to facilitate virtualized server configuration, application deployment and centralized software patch management.
The Enomalism application provides a single interface for managing multiple virtualized servers across assorted platforms. The same administrator can monitor and administer both Linux and Windows servers using the same interface without having to learn extensive OS skills.
Enomalism eases cross-server and large server farm management. Applications can be deployed and updated on many servers simultaneously. The application console provides a centralized look at server information and software versions across all server resources, facilitating versioning and patch management.
Main features:
Enomalism Virtualized Control Center Console
- The Enomalism Control Center is a web-based tool for system administrators to perform many XEN server management tasks from any computer with appropriate Internet or network access.
- Dynamic Real-time Partitioning
- Partition a physical server into 100s of virtualized servers, each with full dedicated server functionality
Resource Management
- Assign and control system resource parameters and re-allocate resources in real-time via a rich web based interface
Virtualization
- Move virtual servers and its application(s) between physical servers transparently with near-zero downtime
Application Repository (package management system)
- Enomalism will feature a package management system & application repository to automate the process of installing, upgrading, configuring, and removing software packages from the system(s).
Open Source License
- Enomalism is Open Source, and is released under an LGPL (GNU Lesser General Public License)

Dwarf Server Framework is a Java technology-based framework for developing network server applications.
The primary goal of Dwarf is to support development of network servers based on the Internet standards. However, its architecture is quite universal and it is not limited to this kind of applications only.
The first available Dwarf-based applications are the Dwarf HTTP Server with Java Servlets and JSP and Dwarf Mail Server with ESMTP/POP3/IMAP4.
Simple design and very concise API together with an extensive documentation makes the learning and consequent work with the framework easy and fast for the development team.
Modular multithreaded architecture as well as efficient implementation guaranties the performance on top. Incorporation of Java 2 Platform Security Architecture and Java Authentication and Authorization Service (JAAS) helps to meet todays high security demands.
Dwarf Server Framework, although not an all-purpose universal wheel, offers extending the server functionality by customizing almost all its components:
- multithreaded service development
- support for TCP/UDP based services
- authentication via login modules
- authorization based on subjects
- logging and configuration
Furthemore, it comes with the full documentation, guides and examples, and is free of charge for the binary redistribution.
Main features:
Main features
- universal multi-threaded server
- generic TCP and UDP protocol handlers
- extensible remote management
- various utility classes (DNS client, queues, caches, etc.)
- XML-based configuration
Security
- application-independent authentication
- subject-based authorization
- proprietary or third party login modules
- SSL/TLS secure communication
Support
- rich documentation with tutorials
- samples with source code included

- free of charge binary redistribution

Apache HTTP Server for Linux 1.3.37 is an application for developing and maintaining an open-source HTTP server for modern operating systems such as UNIX and Windows NT. It aims to provide a secure, efficient and extensible server that provides HTTP services in sync with the current HTTP standards.

The Linux Virtual Server is a highly scalable and highly available server built on a cluster of real servers, with the load balancer running on the Linux operating system.

The architecture of the server cluster is fully transparent to end users, and the users interact as if it were a single high-performance virtual server.

The basic goal of the Linux Virtual Server Project is to:
- Build a high-performance and highly available server for Linux using clustering technology, which provides good scalability, reliability and serviceability.

Virt-Factory project manages virtualized infrastructure:
Virt-Factory focuses on interacting with large numbers of virtual systems and on addressing some of the interaction problems that brings with it
Virt-Factory is primarily aimed at a fairly formal setting (data center), though we hope it is also useful on smaller scales
While Virt-Factory has some uses for bare-metal systems, it is first and foremost a tool for managing virtual systems. Future development will be much more focused on virtual systems management than bare-metal.
Virt-Factory provides both a web UI, for ease of use, and an XMLRPC API, for scripting of admin actions.
Virt-Factory is built on open-source projects including Cobbler, libvirt, and Puppet.
Today, Virt-Factory provisions and manages hosts and guests. It also addresses some of the problems specific to virtual systems. It creates complete host and guest images from metadata descriptions and centrally manages existing images.
Future work will make it possible to abstract away individual hosts and place guests into a pool of equivalent hosts, simplifying the administrators view of the data center for many tasks.
Whats It Run On?
It is being developed on FC-6. Well add support for FC-7 and RHEL-5 shortly.
How Stable Is It?
At this point, virt-factory an alpha level project that will probably eat your brane. However its getting better every day.
Whats the architecture look like?
Virt-factory provides a central server for managing virtual hosts and guests. The server exposes an XMLRPC API that is used by the Web UI, and can also be used by custom scripts. On Managed systems, a special "node daemon" is installed, which the central server communicates with over secure XMLRPC.
Who is the target user?
Developers who want to be involved in new systems management technology. Users wishing to run a large number of virtual systems that have a key interest in virtualization and system recipes / appliance concepts.
How is Virtualization used?
Virtualization plays a core role in virt-factory and is heavily integrated. The software takes care of the nuts and bolts and can entirely manage your virtualization, though logging into virtualization via xm and virsh is still supported. Virt-factory is about enablement of virtualization as a core systems-management strategy.
How do you treat appliances?
Appliances can be defined purely as metadata ("profiles") rather than binary blobs. The metadata describes the required virtual machines attributes (number of processors, memory etc), the base system installation (as a template data for the kickstart file), and the appliances "personality" as a puppet manifest. This makes it possible to distribute appliances easily, and allows end-users to adapt appliances to their needs while still being able to consume appliance updates.
Enhancements:
- This release concentrates on making the code more stable and easier to install/deploy.
