Free transport software for linux

IMS Transport provides a Plone product that supports importing and exporting of IMS packages.
The IMS Transport Tool allows Plone users to upload content in the form of an IMS package.
Although preliminary support is included for popular proprietary learning management system packages, support for extending this product to handle the import or export of any IMS package is also included.
Works with:
- Plone 2.5.1
- Plone 2.5
This is the first major release of this product.

TLSWrap is a TLS/SSL FTP wrapper/proxy for UNIX and Windows, allowing you to use your favourite FTP client with any TLS/SSL-enabled FTP server.
Main features:
- Full encryption of both control and data connections (data encryption is optional, see README).
- Allows existing FTP clients to support Transport Layer Security/Secure Socket Layer.
it gives TLS/SSL support for existing ftp clients
- Works on both UNIX and Windows.
- One process handles all connections (non-blocking I/O).
- A helper process does hostname lookups so the main process is free for other work during slow lookups.
- Both C source and Windows executables for both 32-bit (x86) and 64-bit (x64: AMD64 and EM64T) systems are available.
- Proper support for X.509 certificates
Enhancements:
- This release fixes a bug that could cause crashes on some systems.
- TLSWTray has been upgraded to MFC 8.

DVBStreamer is a Linux application to stream a service from an off-air DVB transport stream over UDP.

A service in this context is an MPEG2 progam which includes all of the PIDs listed in the programs Program Map Table. Confusing DVB call this a service and MPEG a program (although there are reason for this difference which I wont go into).

DVBStreamer doesnt transcode the incoming service but simple forwards all the transport packets belonging to the service over UDP to a reciever. The receiver could be a display application like mplayer/xine/video lan client or it could be a simple recording application to store the received packets to file.

What makes DVBStreamer different from similar applications?

First of all DVBStreamer streams the entire service, that includes the PCR PID which some other applications assume is embedded in the video or audio packets.

Secondly the channels.conf file produced by the linuxtv.org scan application is only used to initialise the list of services and multiplexes, the PID values in file are not used. Instead the SI in the transport stream is monitored and updated when the PAT and PMT tables are updated.

Finally DVBStreamer only retunes to a multiplex, if when switching services the new service is on a different multiplex. This speeds up channel change quite considerably.

This is a unified diff (you probably need GNU patch to apply it) to lame 3.58. Please note that this diff is now obsolete as recent beta versions of lame include a version of this code. Just type "make mp3rtp". The code was broken, but the CVS code is reported to work (and interoperate with playRTPMPEG) as of Feb 21 2000.

Please note that the output stream will only have the correct speed if the input is live recorded stream from your sound card or lame encodes exactly in real-time on your CPU!

RTP is the Realtime Transport Protocol as defined in RFC 1889. It is the transport mechanism of your choice to multicast an mp3 stream.

oRTP is a library implementing the Real-time Transport Protocol (RFC3550), written in C.
oRTP project is easy to use and provides a packet scheduler for sending and receiving packets on time, adaptive jitter compensation, and automatic sending of RTCP compound packets. It works with IPv6.
Main features:
- Written in C
- Implement the RFC3550 (RTP) with a easy to use API with high and low level access.
- Includes support for multiples profiles, AV profile (RFC1890) being the one by default.
- Includes a packet scheduler for synchronizing rtp recv and send. Scheduling is optionnal, rtp sessions can remain not scheduled.
- Implements blocking and non blocking IO for RTP sessions.
- Supports mutiplexing IO, so that hundreds of RTP sessions can be managed by a single thread.
- Supports part of RFC2833 for telephone events over RTP.
- The API is well documented using gtk-doc.
- Licensed under the Lesser Gnu Public License.
- RTCP messages sent periodically since 0.7.0 (compound packet including sender report or receiver report + SDES)
Enhancements:
- This version includes new API documentation built with Doxygen and integrates minor patches and optimizations.

libSRTP library is an open-source implementation of the Secure Real-time Transport Protocol (SRTP) originally authored by Cisco Systems, Inc. It is available under a BSD-style license.
SRTP is a security profile for RTP that adds confidentiality, message authentication, and replay protection to that protocol. It is specified in RFC 3711. More information on the SRTP protocol itself can be found on the Secure RTP Page.
Installation:
./configure [ options ] # GNU autoconf script
make # or gmake if needed; use GNU make
The configure script accepts the following options:
--help provides a usage summary
--disable-debug compile without the runtime debugging system
--enable-syslog use syslog for error reporting
--disable-stdout use stdout for error reporting
--enable-console use /dev/console for error reporting
--gdoi use GDOI key management (disabled at present)
By default, debbuging is enabled and stdout is used for debugging. You can use the above configure options to have the debugging output sent to syslog or the system console. Alternatively, you can define ERR_REPORTING_FILE in include/conf.h to be any other file that can be opened by libSRTP, and debug messages will be sent to it.
This package has been tested on Mac OS X (powerpc-apple-darwin1.4),
Cygwin (i686-pc-cygwin), and Sparc (sparc-sun-solaris2.6). Previous
versions have been tested on Linux and OpenBSD on both x86 and sparc
platforms.
Enhancements:
- Release 1.4.4 is a snapshot of the code in CVS, which has been slowly accumulating minor fixes and extensions.

GNU Anubis is an SMTP message submission daemon. It represents an intermediate layer between mail user agent (MUA) and mail transport agent (MTA), receiving messages from the MUA, applying to them a set of predefined changes and finally inserting modified messages into an MTA routing network.

The set of changes applied to a message is configurable on a system-wide and per-user basis. The built-in configuration language used for defining sets of changes allows for considerable flexibility and is easily extensible.
