Alternatively, use sudo to execute the command as root. See “Executing a Command With sudo” on page 44.

2Enter a new password for the user. The password you enter replaces the password in the file.

Installing SSL

SSL stands for Secure Sockets Layer. It’s a protocol that provides encrypted communications on the Internet.

Before you enable secure administration in QuickTime Streaming Server (QTSS) or Darwin Streaming Server (DSS), you must get a valid certificate signed by a certificate authority such as VeriSign or Thawte. Install the certificate in /Library/QuickTimeStreaming/ streamingadminserver.pem (for Mac OS X) with the information from your certificate file. For Windows, install the certificate in c:\Program Files\Darwin Streaming Server\streamingadminserver.pem. In other supported platforms, install it in /etc/streaming/ streamingadminserver.pem.

Warning If you enable SSL support in Streaming Server Admin, your browser must also support SSL. If it doesn’t, you will not be able to access Streaming Server Admin. If there is a firewall or proxy between the computer on which you are running your browser and Streaming Server Admin, make sure that the firewall or proxy allows SSL requests to pass through. Also, make sure that any routers or NATs (Network Address Translators) between your remote computer and the streaming server allow port 1240 communication.

You need to install the OpenSSL library and Net::SSLeay to support the security functions of DSS. You can get OpenSSL from www.openssl.org. You can get Net::SSLeay from www.perl.com.

Using Automatic Unicast (Announce) With QTSS or DSS on a Separate Computer

You can broadcast from QuickTime Broadcaster to QuickTime Streaming Server (QTSS) or to Darwin Streaming Server (DSS) running on a separate computer using the Automatic Unicast (Announce) transmission method. You’ll need to create a broadcaster user account on the streaming server. This will allow an SDP file to be created on the server. The user name and password that you specify will be entered through QuickTime Broadcaster.

You will need to upgrade your streaming server to QTSS or DSS 4.0 or later if you have an earlier version. If QuickTime Broadcaster is running on the same computer as QuickTime Streaming Server, a broadcaster user account is not required.

To create a user account on the streaming server:

1Create a file named qtaccess in your streaming server Movies directory.

2If you wish to let anyone broadcast to your server, enter the following lines in the file:

QuickTime Streaming Server Darwin Streaming Server specifications

Apple QuickTime Streaming Server, also known as Darwin Streaming Server, is a pivotal technology in the realm of multimedia streaming. Developed by Apple Inc., this open-source server software is designed specifically for the efficient delivery of video and audio content over the internet. One of the standout features of Darwin Streaming Server is its capability to stream content using the QuickTime file format, which is widely adopted for rich media applications.

A core characteristic of Darwin Streaming Server is its support for the Real-Time Streaming Protocol (RTSP). This protocol enables the server to communicate effectively with user clients, ensuring smooth playback of multimedia content. RTSP also allows for advanced streaming capabilities, such as pause, rewind, and fast forward, providing users with a versatile viewing experience.

Darwin Streaming Server is built on a highly modular architecture that enhances its scalability and flexibility. It can easily handle multiple simultaneous streams, making it suitable for both small-scale projects and large-scale broadcast environments. The server can efficiently manage bandwidth, optimizing the delivery of content even during peak usage times.

Another notable feature of Darwin Streaming Server is its robust integration with Apple’s QuickTime technology. This compatibility enables the seamless distribution of interactive media, which is crucial for applications in education, entertainment, and corporate training. The server can stream both live and on-demand audio and video content, catering to a diverse audience.

Additionally, Darwin Streaming Server supports various streaming formats, including MP3 and AAC for audio and H.264 for video. This flexibility allows content creators to deliver high-quality media while maintaining compatibility with various devices and platforms, from desktop computers to mobile devices.

Security is another important aspect of Darwin Streaming Server. It supports encryption protocols, ensuring that sensitive content is protected during transmission. This is particularly valuable for organizations that need to secure proprietary content or deliver private media to specific audiences.

In conclusion, Apple QuickTime Streaming Server, or Darwin Streaming Server, stands out as a powerful tool for multimedia streaming. Its integration of RTSP, compatibility with QuickTime, modular architecture, and robust security features make it an ideal choice for businesses and content creators looking to deliver high-quality streaming experiences. Whether used for live broadcasts or on-demand content, Darwin Streaming Server remains a significant contributor to the evolution of online media delivery.
