Free upnp a software for linux

GUPnP application is an object-oriented open source framework for creating UPnP devices and control points, written in C using GObject and libsoup. The GUPnP API is intended to be easy to use, efficient and flexible.

The GUPnP framework consists of the following two libraries:

GSSDP implements resource discovery and announcement over SSDP.
GUPnP implements the UPnP specification: resource announcement and discovery, description, control, event notification, and presentation (GUPnP includes basic web server functionality through libsoup). GUPnP does not include helpers for construction or control of specific standardized resources (e.g. MediaServer); this is left for higher level libraries utilizing the GUPnP framework.
The GUPnP framework was born out of frustration with libupnp and its mess of threads. GUPnP is entirely single-threaded (though asynchronous), integrates with the GLib main loop, and provides the same set of features as libupnp while hiding most of the UPnP internals through an elegant object-oriented design.

This project is free software released under the GNU LGPL.

upnp2mrtg is a add-on for the mrtg (Multi Router Traffic Grapher). upnp2mrtg is a command line tool written in shell which can gather statistics from an upnp enabled FritzBox DSL router.
Main features:
- shell script
- if your bash is compiled with --enable-net-redirections no netcat is required
- only 1700 bytes or 70 lines of code
- very well tested! ;-))
- very little requirements
- fast
- works

djmount is a UPnP AV client. It mounts as a Linux filesystem the media content of compatible UPnP AV devices.

Djmount discovers automatically all UPnP AV Media Servers on the network and it can make the content available in a directory tree.

An Audio or Video file is rendered as a playlist (.m3u or .ram) which contains an URL for the file. The file can then be streamed by your favorite media player.

djmount is written in C for the Linux operating system.

It is free software, licensed under the terms of the GNU General Public License (GNU GPL).

Petals on a Rose is an intriguing puzzle game for all ages. This website claims that Bill Gates was stumped by it for two days. Its usually played with a group of friends and a set of 5 dice. The game master rolls the dice and tells everyone the answer. This computer version of the puzzle works similarly, only in this case the computer plays as the game master.

To play you just double click the icon to start the program. Type your guess in the "Answer" field and press "Check". If your guess is correct you get congratulated, otherwise you need to try again. If you get tired of guessing you can press the "Give Up" button and youll get the answer to that particular roll.

Just press the "Roll Dice" button at any time to get a new set of numbers.

Always remember, dont tell the answer to anyone!

Have fun, and good luck.

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.

GeeXboX uShare is a UPnP A/V Media Server. It implements the server component that provides UPnP media devices with information on available multimedia files. uShare uses the built-in http server of libupnp to stream the files to clients.

GeeXboX uShare is a fork from the GMediaServer (UPnP Audio Media Server) from Oskar Liljeblad. It has been stripped down for GeeXboX purpose in order to be a lighweight multimedia media server.

By opposition to GMediaServer, it does _NOT_ grab any information from audio files (like ID3 tags) but is _NOT_ limited to audio files. GeeXboX uShare is able to provide access to both images, videos, music or playlists files (see below for a complete file format support list). It does not act as an UPnP Media Adaptor and thus, cant transcode streams to fit the client requirements.

uShare is written in C by Benjamin Zores for the GeeXboX project. It is designed to provide access to multimedia contents to GeeXboX but can of course be used by any other UPnP client device. It should compile and run on any modern POSIX compatible system such as Linux.

GeeXboX uShare is free software - it is licensed under the terms of the GNU General Public License (GPL).

Run a web server inside LAN is a simple script to run a WWW server inside a Local Area Network. Run a web server inside LAN script assume all iptables features are compiled statically in the kernel, or all modules are loaded.

Otherwise you may encounter some surprises trying to utilize the more featureful and creative commandlines that Ive come up with.

Sample:

#external and internal interfaces
EXT=eth0
INT=eth1

# clear everything, and create my cascading chains
iptables -F
iptables -N e0
iptables -N tcpin
iptables -N udpin

# e0 is the name of our chain for eth0
iptables -I INPUT -i $EXT -j e0

# OUTPUT Chain
iptables -A OUTPUT -o $EXT -j DROP -p icmp --icmp-type ! echo-request

# remote gnutella queries were really pissing me off one day
# iptables -A OUTPUT -o $EXT -j DROP -p tcp ! --syn --dport 6346
# iptables -A OUTPUT -o $EXT -j DROP -p tcp ! --syn --sport 6346

# $EXT Chain
# a single rule to accept SYN Packets for multiple ports (up to 15)
iptables -A tcpin -j ACCEPT -p tcp --syn -m multiport --destination-ports 873,993,995,143,80,113,21,22,23,25,53

# stateful connection tracking is wonderful stuff
# ESTABLISHED tcp connections are let through
# If we send a SYN out, the ACK is seen as RELATED
# then further communication is accepted by the ESTABLISHED rule
iptables -A e0 -j ACCEPT -m state --state ESTABLISHED
iptables -A e0 -j ACCEPT -m state --state RELATED

# certain ports I simply DROP
iptables -A tcpin -j DROP -p tcp --syn -m multiport --destination-ports 6346,139

# UDP rules...
iptables -A udpin -j DROP -p udp -m multiport --destination-ports 137,27960

# I run a DNS server, so we must accept UDP packets on port 53
iptables -A udpin -j ACCEPT -p udp -m state --state NEW --destination-port 53

# lets log NEW udp packets on ports 1024:65535, then let them through
iptables -A udpin -j LOG -p udp -m state --state NEW --destination-port 1024:65535 --log-level debug --log-prefix UDPNEW --log-ip-options
iptables -A udpin -j ACCEPT -p udp -m state --state NEW --destination-port 1024:65535

# lets log NEW tcp packets on ports 1024:65535, then let them through

iptables -A tcpin -j ACCEPT -p tcp --syn --destination-port 1024:65535

# lets log INVALID or NEW tcp packets on priveleged ports, then DROP
# (remember I have certain ACCEPT rules higher up the chain)
iptables -A tcpin -j LOG -p tcp -m state --state INVALID,NEW --destination-port 1:1023 --log-level warn --log-prefix TCPPRIV --log-tcp-options --log-ip-options

Linux on a Stick is an attempt to make a Live-CD/USB-Flash server Linux distro. At its heart is a very small and simple Linux distro that boots off CD/Flash and runs from RAM (Ie no spinning hard drives of death).
This approach allows us to strip the OS to its very basic components, which minimizes the amount of resources required. This distro is targeted towards Server administrator who are familiar with Linux, its only configuration method is the command line.
Enhancements:
- Linux kernel 2.4.33 was replaced with 2.6.18.8.
- A USB booting problem that would prevent it from booting on some BIOSs (Namely AMI) was resolved.
- The ARDIS iSCSI target was replaced with the Enterprise iSCSI target (v0.4.14).
- The Open iSCSI initiator (v2.0.754) package with kernel modules is included.
- The distribution now boots on more than just Intel CPUs.
- Userland tools (v3.6.19) and kernel FS support were included for ReiserFS and XFS.
- The PHP CLI is included in php-5.2.0 in root.gz initrd.
