Hi..

First of all.. Don't remove stuff from /etc/services.. thats not the
way to go!!!! If you have a backup of the original services file
i suggest you replace the one you modified with the orginal.. or simply copy it from
another box running the same OS and version...

Please tell me what os you are running ! That really helps..
To check for open ports try: netstat -a |grep LISTEN (should work
on most unixes)

you should check the /etc/inetd.conf
for services and comment them out.. example:

pop3 stream tcp nowait root /usr/sbin/popa3d popa3d

line in /etc/inetd.conf will enable POP3 mail services..
just comment it out to disable it with a
# sign in front like this!

#pop3 stream tcp nowait root /usr/sbin/popa3d popa3d

then find out the pid of inetd and run kill -HUP <PID_OF_INETD_HERE> or simply reboot the server...

You should also check your startup files f�r services (depends on OS and init type where to find them.. please tell me what os you are running. This could be done with the command: uname -a)

You could also checkout if there is a free firewall available for your unix/linux if you want more control of what to let in and out of a server.

Hope this helps some..

aplaymidi

APLAYMIDI(1)						      General Commands Manual						      APLAYMIDI(1)

NAME

       aplaymidi - play Standard MIDI Files

SYNOPSIS

       aplaymidi -p client:port[,...] [-d delay] midifile ...

DESCRIPTION

       aplaymidi is a command-line utility that plays the specified MIDI file(s) to one or more ALSA sequencer ports.

OPTIONS

       -h, --help
	      Prints a list of options.

       -V, --version
	      Prints the current version.

       -l, --list
	      Prints a list of possible output ports.

       -p, --port=client:port,...
	      Sets the sequencer port(s) to which the events in the MIDI file(s) are sent.

	      A  client  can  be  specified  by  its number, its name, or a prefix of its name. A port is specified by its number; for port 0 of a
	      client, the ":0" part of the port specification can be omitted.

	      Multiple ports can be specified to allow playback of MIDI file(s) that contain events for multiple devices (ports), as specified	by
	      "Port Number" meta events.

	      For compatibility with pmidi(1), the port specification is taken from the ALSA_OUTPUT_PORTS environment variable if none is given on
	      the command line.

       -d, --delay=seconds
	      Specifies how long to wait after the end of each MIDI file, to allow the last notes to die away.

BUGS

       aplaymidi handles "Port Number" meta events, but not "Port Name" meta events.
