ciao a tutto sto cercando di imparare a fare degli script di avvio basandomi sul modo naturale di debian,non amo terzi programmi ecc..solo bash e quindi update-rc.d

vorrei linkare agli rcX uno script noip2 che parte in automatico al boot basandomi sul file example di debian la mia modifica è stata questa:

#! /bin/sh
#
# skeleton example file to build /etc/init.d/ scripts.
# This file should be used to construct scripts for /etc/init.d.
#
# Written by Miquel van Smoorenburg <miquels@cistron.nl>.
# Modified for Debian

# Further changes by Javier Fernandez-Sanguino <jfs@debian.org>
#
# Version: @(#)skeleton 1.9 26-Feb-2001 miquels@cistron.nl

root@debian:/home/raf# ./x start
Starting noip2: ERROR.

anche se l'output da errore alla fine starta il programma noip mentre

root@debian:/home/raf# ./x stop
Stopping noip2: root@debian:/home/raf#

ma facendo ps aux il programma è ancora in esecuzione,qualcuno sarebbe cosi gentile da riscrivermi qui il file e magari sottolineando dove ha
corretto cosi capisco dove ho sbagliato,cosi che posso anche fare altri script grazie
