Free miniupnp client software for linux

MiniUPnP Client and Daemon is an UPnP IGD client lightweight library and UPnP IGD daemon.
The UPnP protocol is supported by most home adsl/cable routers and Windows 2K/XP. The aim of the MiniUpnp project is to bring a free software solution to support the "Internet Gateway Device" part of the protocol.
The Linux SDK for UPnP devices (libupnp) seems too heavy for me. I want the simplest library possible, with the smallest footprint and no dependencies to other libraries such as XML parsers or HTTP implementations. All the code is pure ANSI C.
Compiled on a x86 PC, the miniupnp client library have less than 15KB code size. For instance, the upnpc sample program is around 20KB.
The project is divided in two main parts : the client library, enabling applications to access the services provided by an UPnP "Internet Gateway Device" present on the network, and the miniupnpd daemon, providing these services to your network from a linux or bsd box being the gateway. At the moment the miniupnpd is developped on OpenBSD 3.0+ with pf. You can see some of the work I have done to integrate with pf on this page.
As pf is also available under FreeBSD, guys at the pfSense project have ported miniupnpd to this system.
For some reasons, it may be not the good solution for you to use the code from the MiniUPnP project directly.
As the code is small and simple to understand, it is a good base to take inspiration for your own UPnP implementation. The KTorrent team UPnP plugin in C++ is a good example.
If you are wondering which home router is working with the miniupnp client, you can find the answer here. In fact, you are more likely to help me fill the list by sending me an email.
Usefulness of the miniUPnP client library
The usage of the miniUPnP client library is useful whenever an application needs to listen for incoming connections.
Examples : P2P applications, FTP clients for active mode, IRC (for DCC) or IM applications, network games, any server.
The typical usage of UPnP capabilities of a router is a file tranfert using MSN messenger. The MSN Messenger software uses the UPnP API of Windows XP to open port for incoming connection. To mimic the MS software, it is a good idea to use UPnP as well.
Enhancements:
- This release adds changes to accommodate the Linux 2.6.22 kernel.

NNTP Client Lib is a Java implementation of RFC 997 for newsreaders, with support for authentication and logging.
NNTP Client Lib is meant to be used by newsreader implementations as some NNTP commands irrelevant for newsreaders are not implemented. Support for MIME or any other article encoding is not included.
If you want to quickly see nntpClientLib working, run NewsDemo . Note that this prints every message to System.err; you can edit NewsDemo.java and choose any other PrintStream.
KNOWN ISSUES:
- The POST and AUTHUSER commands havent been tested (yet).
TODO List:
- FIX NNTPConnectionImpl.disconnect() NullPointerException if host is unreachable.
- Add SSL support.
Enhancements:
- A new logging system and code cleanup.

Mnemona GUI Client is a Java application that provides a GUI interface for accessing sets in a trove managed by a Mnemona Trove Server.

It communicates with the trove server via Java RMI and supports SSL.

It uses the same GUI design as Fingerstring. It contains a full range of commands for creating, searching, and modifying Mnemona sets.

It also has a command for creating users, so it can be used (by a root user) to manage a Mnemona trove server. Commands are invoked through a standard menu arrangement.

PHP FTP Client is an FTP client that is useful for allowing people behind a firewall access to FTP without opening the FTP ports inside the firewall.
It could be used as a front end to a local FTP server, and therefore allow the administrator to provide access to the FTP server only from localhost.
Main features:
- Provide FTP access through a firewall which blocks FTP
- Provide a front end to an FTP server which only allows access to the web server, thus reducing the risk of the FTP server being attacked.
Enhancements:
- Have corrected problems with missing files. Was a case of linking against files I shouldnt have been.
- Added an FAQ, which currently only explains how to use the multi-file upload feature.

Tiny ERP Web client is a Turbogears/AJAX interface for the enterprise management software Tiny ERP.

The project supports all features of the GTK client and connects to the Tiny ERP server using XML-RPC.

SILC (Secure Internet Live Conferencing) is a protocol which provides secure conferencing services in the Internet. It can be used to send any kind of messages, in addition to normal text messages.
This includes multimedia messages like images, video, and audio stream.
All messages in the SILC network are encrypted and authenticated, and messages can also be digitally signed. SILC protocol supports AES, SHA-1, PKCS#1, PKCS#3, X.509, OpenPGP, and is being developed in the IETF.
The software is delivered as SILC Client for end users, SILC Server for system administrators, and SILC Toolkit for application developers.
Enhancements:
- This version fixes several crash bugs and other minor bugs.

HTTP Proxy Client is the small set of libraries and scripts, which provides transparent access to Internet via HTTP proxy for programs, which uses TCP/IP for communication.
The list of programs includes: telnet, ftp, licq, cvs, smth else? Project implements dynamic library, that can be preloaded before program run.
The library substitutes some system calls (connect(), gethostbyaddr(), gethostbyname()), with calls, which makes TCP/IP connection through HTTP proxy. This allows client programs behind HTTP proxy work with Internet without limitations.
At the moment tested on i386 Linux, i386/sparc Solaris.
Enhancements:
- While using dotted address, applications will attempt to connect regardless DNS lookup result.
