Troubleshooting
1

i can start noip2 with following commands from terminal

noip2
/etc/init.d/noip2 start
but i cannot start it via cron or rc.local
i ran

chmod +x /etc/init.d/noip2

but

update-rc.d noip2 defaults

gives me following error

update-rc.d noip2 defaults
insserv: warning: current start runlevel(s) (empty) of script `noip2' overrides LSB defaults (2 3 4 5).
insserv: warning: current stop runlevel(s) (0 1 2 3 4 5 6) of script `noip2' overrides LSB defaults (0 1 6).

this is my /etc/init.d/noip2
