Operating Systems AIX Problem opening port 9998 Post 83851 by erica057 on Tuesday 20th of September 2005 08:39:40 AM

Thank you bakunin! I see that I was getting my terminology confused; thank you for the explanation. Yes, I was trying to create a daemon that listens on port 9998. Here is what I did:

First, I added this to /etc/services

Code:
tcpTest     9998/udp

Then, I added this to inetd.conf

Code:
tcpTest  stream  tcp  nowait  root  /path/to/a.out  a.out

(yes, I know that a.out is a generic name, this is the path to a specific binary).

tcpTest is present when I type "smit inetdconf".

I tried first refreshing inetd.conf, then killing inetd.conf and restarting it, and it did not work. It does not show up when I type ps, nor when I telnet into port 9998, nor when I scan it with nmap. When I type "startsrc -s tcpTest", it says "0513-085 the tcpTest Subsystem is not on file". It works when I try to start, say, tftpd, so I'm not sure what file it is pulling from.

Any thoughts?

Thanks in advance!
--Erica

EDIT: I also tried adding it to inittab to no avail.

auscope

AUSCOPE(1)						      General Commands Manual							AUSCOPE(1)

NAME

       auscope - 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 automati-
       cally 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
