To execute a command as root:

mOpen a terminal window and type sudo followed by a space and then the command you want to execute. You will be prompted for an administrator password before the command executes.

For example, to execute the kill command using sudo, you would enter the following in a terminal:

[host:~] user# sudo kill 529 530

where 529 and 530 are process IDs.

For more information about sudo, enter man sudo in a terminal.

Streaming on Port 80

If you are setting up a streaming server on the Internet and you think some of your clients are behind firewalls that allow only web traffic, enable streaming on port 80. This lets the streaming server accept connections on port 80, the default port for web traffic, and QuickTime clients will be able to connect to your streaming server even if they are behind a web-only firewall. If you enable streaming on port 80, make sure you disable any Web server on the same computer that may conflict with your streaming server.

Firewalls and Networks With Address Translation

The streaming server sends data using User Datagram Protocol (UDP) packets. Firewalls designed to protect information on a network often block UDP packets. Client computers located behind a firewall that blocks UDP packets can’t receive streamed media. However, the streaming server also allows streaming over HTTP connections, which allows streamed media to be viewed through even very tightly configured firewalls.

Some client computers located on networks that use address translation may also be unable to receive UDP packets, but they can receive media that’s streamed over HTTP connections.

If users have problems viewing media through a firewall or via a network that uses address translation, they should upgrade their client software to QuickTime 5 or later. If users still have problems, their network administrators should provide them with the appropriate settings for the Streaming Proxy and Streaming Transport settings on their computers.

Network administrators can also set their firewall software to permit RTP and RTSP throughput.
