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).

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.

NNML::Server is a minimal NNTP server.

SYNOPSIS

perl -MNNML::Server -e server
perl -MNNML::Server -e unspool

NNML::Server server implements a minimal NNTP server. It is (hope-) fully conformant to rfc977. In addition the commands XOVER and AUTHINFO are implemented.

Supported commands:

ARTICLE, AUTHINFO, BODY, GROUP, HEAD, HELP, IHAVE, LAST, LIST,
MODE, NEWGROUPS, NEWNEWS, NEXT, POST, QUIT, SLAVE, STAT

XOVER, XHDR, LIST NEWSGROUPS ng-spec

The main reason for writing this was to synchronize my mail directories across different hosts. The Mail directories are MH-Style with a .overview file in each folder and an active file in the base directory. These are maintained by the Emacs Gnus backend NNML. To get started, you can generate/update this files using the overview program. Upon POST and IHAVE commands this files will also be updated.

To start from scratch use:

touch /tmp/active;
perl -MNNML::Server -e server(base => "/tmp", port => 3000)

To export your mh-Mail use:

perl overview -base ~/Mail
perl -MNNML::Server -e server(base => "$ENV{HOME}/Mail", port => 3000)

The command POST and IHAVE honour the Newsgroups header if not overwritten by the X-Nnml-Groups header. Articles will contain an appropriate X-Nnml-Groups header when retrieved by message-id.

When the client submits the SLAVE command, all forther post requests are spooled in $Config-spool> (usually ~/Mail/NNML.spool) for performance reasons. You can process the spooled articles by submitting the XUNSPOOL command or by calling

perl -MNNML::Server -e unspool

Rejected articles will be saven in $Config-bad> (usually ~/Mail/NNML.bad)

C++ Server Pages is a partial Java server pages and servlet implementation in C++. C++ Server Pages is written as Apache 2.0 modules, with the focus on performance.

pDonkeyS is Perl implementation of an eDonkey server. The main goal of the server is to provide framework for further eDonkey protocol exploration, but it could be useful in testing of client software, since the server can be configured to output very detailed debugging info about eDonkey traffic.
