mCheck the error log.

Streaming Server Admin Is Not Responding

mVerify that the streamingadminserver.pl script is running. If not, log in as root (or administrator in Windows), open a terminal window, and start the Streaming Server Admin process by typing

/usr/sbin/streamingadminserver.pl

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

The Server Doesn’t Start Up or Quits Unexpectedly

mCheck the error log.

mMake sure the QuickTimeStreamingServer ﬁle (for QTSS) or the DarwinStreamingServer ﬁle (for DSS) is in the /usr/sbin/ directory.

The Streaming Server Computer Crashes or Is Restarted

mWith QuickTime Streaming Server (QTSS) 4.1 or later, when the computer restarts, playlists start up automatically. With QTSS 4.0, once the computer starts up, you may need to restart playlists, even if Streaming Server Admin indicates they are playing.

mMake sure the streaming server is running before you restart the playlists.

mIf you were using the streaming server to relay broadcasts using the Default Relay feature, you need to restart the broadcasts on the other streaming servers that were relaying to this server using the RTSP Announce protocol. Likewise, any TCP or RTSP Announce relays must be restarted on the server after it has restarted.

Media Files Do Not Stream Properly

mTry streaming a sample movie to see if the server can stream it. A sample movie is included with the server.

If the server streams the sample movie, the problem may be with the way your movie ﬁle is prepared. Recreate the movie.

If the sample movie doesn’t stream, the problem may be with the server computer or the network.

mCheck streaming server activity and, if necessary, reduce the maximum number of connections or throughput.

mIf the problem occurs on a client computer, make sure the user has the appropriate Streaming Proxy and Streaming Transport settings. The administrator for the client computer’s network should be able to provide the correct settings.

mMake sure the client software supports the ﬁle format being broadcast.

mCheck the structure of the URL.
