sudo chown root:root /etc/init.d/noip2
sudo chmod 755 /etc/init.d/noip2
according to http://wiki.debian.org/LSBInitScripts/DependencyBasedBoot
instead of
update-rc.d noip2 defaults
add "INIT INFO" to /etc/init.d/noip2
### BEGIN INIT INFO
# Provides: noip2
# Required-Start:

# Should-Start:
# Should-Stop:
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: Start and stop directadmin
# Description: DirectAdmin
### END INIT INFO
then
sudo insserv noip2(with out the INIT INFO, the error "insserv: warning: script 'X' missing LSB tags and overrides" will be shown.)
the whole file will be
