Managing Your Streaming Server 45
To execute a command as root:
m Open 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.
Problems
This section provides information on what to do if you encounter certain problems while
streaming media.
