Free client server application software for linux

SOPE Application Server is an extensive set of frameworks (16 frameworks, ~1500 classes) which form a complete Web application server environment.
Besides the Apple WebObjects compatible appserver extended with Zope concepts, it contains a large set of reusable classes: XML processing (SAX2, DOM, XML-RPC), MIME/IMAP4 processing, LDAP connectivity, RDBMS connectivity, and iCalendar parsing.
The individual frameworks of the package can be used standalone (for example in Cocoa applications) and do not require the application server itself.
For MacOSX developers, the package includes SOPE:X, which contains special Xcode and Cocoa support for SOPE.
Enhancements:
- This release fixes a set of minor bugs.
- It improves the vCard parser, the IMAP4 client library, the MySQL adaptor, and BSD packaging.

LAMP Application Server project is a combination of common open source tools that provides a unified system from which administrators, developers, and other parties can manage a large application cluster. The underlying platform is LAMP based.
Enhancements:
- Fixed vhost config to correctly handle index pages on static directory area
- Fixed a MySQL install bug. Table `domain_dns_config` is now MyISAM like the rest.

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.

JOPE is an implementation of the SOPE server and concepts in Java 1.5. JOPE Application Server provides (yet another) templating engine modelled after the WebObjects one, as well as database access libraries and other features.
JOPE applications can be deployed into a Servlet container or run standalone using the Jetty HTTP server.
Enhancements:
- This release has various improvements in the database layer plus several convenience enhancements in the template parser.

Darwin Calendar Server provides a CalDAV server.

The Darwin Calendar Server is a standards-compliant server that allows multiple users to collaboratively share calendaring information. It provides a shared location on the network to store schedules, and allows users to send each other and manage invitations.

In order to provide interoperability with multiple calendaring clients, the server implements the CalDAV protocol, which is an extension of WebDAV, which is in turn an extension of HTTP.

The VTQLserver package contains a server and clients for videotext access for Linux. The server stores the pages of several TV-stations for parallel reading and searching.

You can run many clients in parallel i.e. search all videotext pages, and view them. The only limit is, that the server does not scale well and is not as stable as you may expect it for running it on a server machine. It is intended to be used on workstations, since I do not think, servers have TV cards nor do I have a server machine.

SS5 is a socks server that implements the SOCKS v4 and v5 protocol. As a proxy server, SS5 authenticates, profiles and processes network requests for clients.
Socks Server 5 establishes connections to application hosts for client applications. When the client attempts to access the network, the client connects to the SS5 daemon instead of the application host.
Following authentication, clients request that SS5 perform network activities for the client.
The activities might include:
CONNECT
BIND
UDP ASSOCIATE
The SS5 protocol is independent of application protocols, and can assist with different networking services, including telnet, ftp, finger, whois, gopher, and WWW access.
Enhancements:
- Fix code
