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).

QEMU Server Tools is a set of simple command-line scripts for managing multiple QEMU VMs easily without requiring a graphical frontend.

QEMU Server Tools organizes VMs into directories and mimics the usage of command line tools from VMware Server.

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.

Linx Kiss Server project was primarily intended for personal purpose. I couldnt make any of available kiss linux servers work with my new Kiss DP-600 player in a way I would imagine so I found kissd simple kiss daemon by Alexandre Becoulet which is really simple and clear code to understand and fixed it up and added some more features.
Linux Kiss Server (LKS) works with Kiss DP-600 but I think it should work with any other Kiss player as well.
Main features:
- makes selected direcotory accessible for Kiss player
- can run either as a daemon or in foreground
- can answer Kiss player queries for PC-LINK server
- can disable UDP binding at all (doesnt respond to Kiss player looking for PC-LINK server queries)
- can overide default server port
Enhancements:
- A problem with zombie processes when the opening of files failed was fixed.
- TIME_WAIT sockets are now closed correctly.
- Events are now logged using syslog when the server is run in daemon mode.
