以下のファイルを /etc/init.d/noipとし、その後 chmod +x /etc/init.d/noip を実行

 #! /bin/sh
 #
 # no-ip

 case "$1" in
         start)
                 echo "Starting noip."
                 /usr/local/bin/noip2
                 ;;
         stop)
                 echo -n "Shutting down "
                 #killproc noip
                 start-stop-daemon --user root --stop --quiet --oknodo --exec /usr/local/bin/noip2
                 echo "."
                 ;;
         restart)
                 $0 stop
                 $0 start
                 ;;
         *)
                 echo "Usage: $0 {start|stop|restart}"
                 exit 1
 esac
 exit 0
