Net::Server is an extensible, generic Perl server engine. Net::Server combines the good properties from Net::Daemon (0.34), NetServer::Generic (1.03), and Net::FTPServer (1.0), and also from various concepts in the Apache Webserver.
Net::Server attempts to be a generic server as in Net::Daemon and NetServer::Generic. It includes with it the ability to run as an inetd process (Net::Server::INET), a single connection server (Net::Server or Net::Server::Single), a forking server (Net::Server::Fork), a preforking server which maintains a constant number of preforked children (Net::Server::PreForkSimple), or as a managed preforking server which maintains the number of children based on server load (Net::Server::PreFork). In all but the inetd type, the server provides the ability to connect to one or to multiple server ports.
Net::Server uses ideologies of Net::FTPServer in order to provide extensibility. The additional server types are made possible via "personalities" or sub classes of the Net::Server. By moving the multiple types of servers out of the main Net::Server class, the Net::Server concept is easily extended to other types (in the near future, we would like to add a "Thread" personality).
Net::Server borrows several concepts from the Apache Webserver. Net::Server uses "hooks" to allow custom servers such as SMTP, HTTP, POP3, etc. to be layered over the base Net::Server class. In addition the Net::Server::PreFork class borrows concepts of min_start_servers, max_servers, and min_waiting servers.
Net::Server::PreFork also uses the concept of an flock serialized accept when accepting on multiple ports (PreFork can choose between flock, IPC::Semaphore, and pipe to control serialization).

The Apache HTTP Server Project is an effort to develop and maintain an open-source HTTP server for modern operating systems including UNIX and Windows NT. The goal of this project is to provide a secure, efficient and extensible server that provides HTTP services in sync with the current HTTP standards.
Apache has been the most popular web server on the Internet since April of 1996. The May 2003 Netcraft Web Server Survey found that 62% of the web sites on the Internet are using Apache, thus making it more widely used than all other web servers combined.
The Apache HTTP Server is a project of the Apache Software Foundation.

Nexedi Desktop Linux Server (DLS) is a LiveCD which instantly provides 500+ Linux Desktop applications to all PCs in a Local Area Network (LAN).

It is compatible with Windows, MacOS, Unix or GNU/Linux environments as well as with eBox thin clients. Nexedi DLS also includes a complete network infrastructure solution (file server, mail server, collaboration server, directory service, etc.) based on modern protocols (ex. LDAP, Samba 3, IMAP, etc.).

Nexedi DLS Live CD allows small and medium size organisations to implement a high end Linux desktop and network infrastructure solution in one minute.

Nexedi DLS is a LiveCD: it requires no installation. Simply insert the LiveCD in any PC, turn on the PC and choose the boot from CD option.

After about one minute, a complete Mandrakelinux server is ready to serve thin clients and provide file sharing, directory, messaging and collaboration services to your entire network. Enter your network information through a simple web based interface.

You can now access all Nexedi Desktop Linux Server features from any other PC in the same local network.

Nexedi DLS LiveCD can be used from any standard PC based on x86 architecture (Pentium, Athlon, Opteron, etc.). 512 MB RAM is recommended to serve a few users. 1024 MB and a fast CPU (Pentium IV, Pentium M, Athlon, Opteron, etc.) is recommended to server 10 simultaneous users.

Applications:

Nexedi DLS applications are multiple. Some applications are based on DLS acting as a complement to existing infrastructure. Other applications are based on DLS acting as a replacement to existing infrastructure.

* Office and Productivity:many Mandrakelinux applications can be very useful as a complement to existing Windows or Macintosh environments. Installing a single DLS server allows in a network allows everyone to access those applications without requiring any complex software installation or setup.
* Internet Security:by placing a DLS server in the DMZ of an organisation, it is possible to protect all PCs in a local network from viruses or spyware. Internet applications are launched on the DLS server and accessed by users through tightVNC from Windows or Macintosh PCs. Internet attacks might compromise the DLS server but will not be able to access sensitive data on users PCs. This architecture is similar to having two physical networks, one for internal uses, one for internet access, but at a much lower cost.
* Software Development Box:a single DLS server can be used as a shared multi-platform software development by Windows or Macintosh users. Mandrakelinux includes many advanced integrated development environments (IDE) which can be used to produce GUI, Web or embedded applications.
* Network Administration Box:a single DLS server can be used as a shared network administration environment. Mandrakelinux includes many advanced and free network administration tools.
* Thin Client Server:Nexedi DLS is a multi-protocol thin client server and gateway. A typical DLS server can handle 10 simultaneous sessions. Thin clients can use the VNC, tightVNC or XDMCP protocols to access a complete desktop session. Any DLS session can access other thin client protocols (RDP, X11, NX, etc.). Nexedi DLS also includes various emulators and virtualizers which allow to run Windows and Macintosh applications directly.

OfficeSpot.Net CS contains following packages: - eGroupWare - OpenLDAP - DBMail - ClamAV - APC - Memcache - MySQL
Enhancements:
- This release contains updated versions of eGroupWare (1.4), DBMail (latest stable SVN revision), and ClamAV (0.90.3).
- The installation process was streamlined and the online documentation was updated.

Twisted Mail project provides client and server implementations of SMTP, POP3, and IMAP4.
These differentiate themselves from the Python standard library implementations both by presenting a much higher-level, easy-to-use interface and in their server components, which allow the implementation of custom servers for each protocol without dealing with protocol-level issues.
Twisted Mail includes a simple demonstration email server which accepts messages over SMTP, stores them in a Maildir arrangement, and can serve them to clients over POP3.
Enhancements:
- The IMAP4 client now properly quotes usernames and passwords when necessary.
- It also handles unsolicited FLAGS responses.
- The IMAP4 server can now parse multiple literals in a single command and to FETCH requests with multiple BODY parts.
- A bug where Deferreds returned from IMAP4 client methods would not receive connection lost notification has been fixed.
- Startup time on OS X has been improved.
- The SMTP server has been sped up.
- The POP3 mailbox API has been expanded to allow Deferreds to be returned in some cases.

Net::CyanChat::Server is a Perl interface for running a CyanChat server.

SYNOPSIS

use Net::CyanChat::Server;

our $cho = new Net::CyanChat::Server (
host => localhost,
port => 1812,
debug => 1,
);

# Start the server.
$cho->connect();

# Loop.
$cho->start();

Net::CyanChat::Server is a Perl interface for running your own CyanChat server (or, rather, to run a chat server based on the CyanChat protocol that other CC clients would recognize).
