Network Audio System Protocol Filter

Synopsis

auscope [ option ] ...

Description

auscope is an audio protocol filter that can be used to view the network packets being sent between an audio application and an audio server.

auscope is written in Perl, so you must have Perl installed on your machine in order to run auscope.  If your Perl executable is not installed as /usr/local/bin/perl, you should modify the first line of the auscope script to reflect the Perl executable's location.  Or, you can invoke auscope as

perl auscope [ option ] ...

assuming the Perl executable is in your path.

To operate, auscope must know the port on which it should listen for  audio clients, the name of the desktop machine on which the audio server  is running and the port to use to connect to the audio server.  Both the  output port (server) and input port (client) are automatically biased by  8000.  The output port defaults to 0 and the input port defaults to 1.

Arguments

-i<input-port>

Specify the port that auscope will use to take requests from clients.

-o<output-port>

Determines the port that auscope will use to connect to the audio  server.

-h<audio server name>

Determines the desktop machine name that auscope will use to find  the audio server.

-v<print-level>

Determines the level of printing which auscope will provide.  The print-level can be 0 or 1.  The larger numbers provide greater output detail.

Examples

In the following example, mcxterm is the name of the desktop machine  running the audio server, which is connected to the TCP/IP network host tcphost.  auscope  uses the desktop machine with the -h command line option, will listen for client requests on port  8001 and connect to the audio server on port 8000.

Ports (file descriptors) on the network host are used to read and  write the audio protocol.  The audio client auplay will connect to the audio server via the TCP/IP network host tcphost  and port 8001:

auscope -i1 -o0 -hmcxterm

auplay -audio tcp/tcphost:8001 dial.snd

In the following example, the auscope verbosity is increased to 1, and the audio client autool will connect to the audio server via the network host  tcphost, while displaying its graphical interface on another  server labmcx:

auscope -i1 -o0 -hmcxterm -v1

autool -audio tcp/tcphost:8001 -display labmcx:0.0
