Free bittorrent protocol software for linux

The HTTP Time Protocl (HTP) system is a set of utilities to set and maintain the system clock from the HTTP/1.1 (RFC 2616) "Date:" header. HTP requires Libconfig.
The purpose of HTP is provide a simple to use system that can be used on any system that is connected to the internet and can access atleast one web page (either directly or through a proxy) to be able to maintain an accurate clock.
HTTP Time Protocol uses basic statistical analysis to arrive at the most accurate time possible given enough servers. The more servers HTP is configured to use the more accurate the clock can be.
Enhancements:
- Cleanup/simplification of the code.
- A more robust implementation of the "-p" (precision) switch.

Digital Camera Protocol is another command-line utility for DC21x cameras, this one looks and works just like "ftp" command. Not written by me, but uses some of my low-level Kodak code from digicam.

Gnome BitTorrent Downloader is not meant to be an entire front-end, just a program that pops up when you "execute" the torrent files.

Since BitTorrent is written in Python, I figured Id write this program in Python too; saves a lot of trouble as I already knew Python relatively well.

STUN Protocol Library provides the Simple Traversal of UDP through NATs Library.
STUN Protocol Library, Client and Server implements a simple STUN (Simple Traversal of UDP through NATs) server and client, using the included library.
The STUN protocol is described in the IETF RFC 3489, available from the IETF.
STUN is a lightweight protocol that allows applications to discover the presence and types of Network Address Translators (NATs) and firewalls between them and the public Internet.
It also provides the ability for applications to determine the public IP addresses allocated to them by the NAT.
STUN works with nearly all existing NATs, and does not require any special behavior from them.
As a result, it allows a wide variety of applications to work through existing NAT infrastructure.
The STUN protocol is very simple, being almost identical to echo.
Enhancements:
- Changed to new terminology.

Whamb Sharing Protocol Daemon (WSD) is a perl script that allows you to share MP3 or OGG on a Unix/Linux or windows system.WSD needs perl 5.7.3 or later (5.8.0 recommended) and some modules (HTML::Entities, Encode, MP3::Info), you will find any instructions you need in the readme, so please read it ! WSD also needs RendezVous from Apple, its opensource and runs on lots of platform including linux/*BSD/Windows/Solaris and all Posix OSes

Installation is simple but depends by your operating system:
make os=linux on linux
make os=opensd on openbsd
make os=osx on macosx
make os=solaris on solaris

if you are running NetBSD or FreeBSD edit the makefile you will see:
ifeq ($(os),openbsd)
CFLAGS_OS = -DHAVE_SOCKADDR_SA_LEN -DHAVE_DAEMON -DHAVE_SOCKLEN_T -DHAVE_BROKEN_RECVDSTADDR
change it to
ifeq ($(os),bsd)
CFLAGS_OS = -DHAVE_SOCKADDR_SA_LEN -DHAVE_DAEMON -DHAVE_SOCKLEN_T

and use make os=bsd

You can start it with something like: build/mDNSResponderPosix -n "`hostname`" -t _whamb._tcp. -p 7603 -d
You may also want to copy mDNSResponderPosix to your /usr/bin directory

ZRTP Protocol Library is an implementation of Phil Zimmermanns ZRTP protocol, created based on and interoperable with Zfone beta 2.

Using this package, together with GNU ccrtp (1.5.0 or later) provides a zrtp implimentation that can be directly embedded into client and server applications, rather than the overhead penalty of using an external proxy such as zphone. The first application to demonstrate this capability is the 0.8.2 release of the Twinkle softphone client.

Please note, this library is licensed under the GNU GPL, version 2 or later, and has been copyright assigned to the Free Software Foundation.

Host Identity Protocol on Linux is an implemetation of the Host Identity Protocol (HIP) and the related architecture. Host Identity Protocol (HIP) is a proposal to change the TCP/IP stack to securely support mobility and multi-homing.
Additionally, it provides for enhanced security and privacy and advanced network concepts, such as moving networks and mobile ad hoc networks. HIP is "cool", which means that as a mobile VPN solution, when your network interfaces go up or down, there is no need to re-establish a secure tunnel.
Enhancements:
- The implementation was moved from kernel to user space.
- Support for the Nokia 770 Linux PDA (ARM) was added.
