starting a new service

Hi,
I have root access to my machine,
I need to add a service to this machine console based.
I need a service running on a port and server may be /bin/ls

It must not ask any username and password. line we can place in init.d or xinit.d and cabe be like

i assume this service will be like...

service myname
{
 disable = no
socket-type = stream
wait = no
server = /bin/sh
//must give a port number to activate.
}

Can anyone please make necessary connections and also steps to do in starting and stoping the service.

Thank You,
Prashanth
