WidgetServer is a component based Java/XML server-side GUI-framework which enables an application to run as either
- a monolithic application with a Swing GUI,
- a client/server application with a thin Swing client,
- or as an application with a rich Web client based on HTML and JavaScript
without any change and without loss of functionality!
WidgetServer gives you the choice if you develop a GUI either using
- HTML markup,
- a Java API like Swing,
- or XML markup.
XML markup helps to define an applications GUI fully separated from java code, Java code is useful for dynamic creation and modification during application runtime, while HTML markup is the best choice for typical web applications.
WidgetServer provides a unified component-based, object-oriented programming interface for Web and Swing GUIs to control and modify the GUI and to process events. The framework prevents from struggling with HTML, JavaScript and HTTP requests or from caring about the internals of Swing (e.g. Drag and Drop implementation).
For Swing client/server applications the framework cares for the client/server split as well as for the client/server communication including compression and security layers. Web applications are fully AJAX enabled while this feature remains fully configurable.
The framework also supports a mixed deployment mode, which enables one server to serve Swing clients and Web clients at the same time. The functionality of the Swing widget set is covered widely (and sometimes enhanced) in both (Swing and Web/HTML) client channels.
The project comes with a WYSIWYG GUI-builder which is completely build on the Wi.Ser-framework technology.
Enhancements:
- This version fixes some bugs in the JavaScript library.
- The Component-Set example is more interactive now.
- A new component similar to JSpinner has been added.
- A new package to create wizard based applications by declaration was added.
- Some enhanced error messages help to detect XML configuration errors now.

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.

GPM client library (libgpm) package is an stand-alone version of GPMs client library, used by many console applications for mouse access.
Despite the (now quite aged) GPM package it contains just the client part (no server), and provides a pkgconfig descriptor (libgpm.pc) for easy importing.
Enhancements:
- This release pulls in some outstanding patches from upstream and Gentoo. It adds a Gentoo ebuild file.

Net::Nessus::Client is a Nessus client module.

SYNOPSIS

# Connect to the Nessus Server
require Net::Nessus::Client;
my $client = Net::Nessus::Client->new(host => localhost,
port => 1241,
user => joe,
password => my_password);

The Nessus program is a Client/Server application offering a framework for lots of security related scanners, so-called plugins. The idea is not to create a separate scanner for any possible security hole, but to reimplement only the most important parts and let the Nessus Server (nessusd) do the most part of the work.
Clients are typically available as GUI applications, for example based on the GTK (nessus), Java or Win32 applications. This module is another Nessus client written in Perl, but without GUI.

You start using the module by opening a connection to a Nessus Server: This will create a Nessus client object for you. This object offers methods that you can later use, for example retrieving the list of available plugins, start a scan, set preferences and so on.
