knowledge from: http://www.linuxquestions.org/questions/linux-software-2/how-do-i-execute-inadyn-automatically-during-boot-541367/
And
Init script for Inadyn
First of all you have to create (or edit) inadyn configuration file:
$~ mkdir /var/cache/inadynEdit this file:
/etc/inadyn.conf
this way
Code:# Basic configuration file for inadyn # # /etc/inadyn.conf #update_period_sec 600 # Check for a new IP every 600 seconds background verbose 1 period 300 cache-dir /var/cache/inadyn startup-delay 60 logfile /var/log/ddns.log pidfile /var/run/ddns.pid system default@freedns.afraid.org ssl username abcdefsafdsa password fdadfferfsadf alias oneofyour.donated.com alias another.tooms.to
Now put this code in /etc/init.d/inadyn
Then create these two links to start and stop service at system boot and shutdown:Code:#!/bin/bash case "$1" in start) if [ -f /tmp/inadyn.pid ]; then PID=$(cat /tmp/inadyn.pid) kill -0 ${PID} &>/dev/null if [ $? = 0 ]; then echo "Inadyn is already running." else /usr/sbin/inadyn pidof inadyn > /tmp/inadyn.pid PID=$(cat /tmp/inadyn.pid) kill -0 ${PID} &>/dev/null if [ $? = 0 ]; then echo "Inadyn started succesfully." else echo "Error starting Inadyn" fi fi else /usr/sbin/inadyn pidof inadyn > /tmp/inadyn.pid PID=$(cat /tmp/inadyn.pid) kill -0 ${PID} &>/dev/null if [ $? = 0 ]; then echo "Inadyn started succesfully." else echo "Error starting Inadyn" fi fi ;; stop) if [ -f /tmp/inadyn.pid ];then PID=$(cat /tmp/inadyn.pid) kill -0 ${PID} &>/dev/null if [ $? = 0 ]; then /bin/kill ${PID} kill -0 ${PID} &>/dev/null if [ $? = 1 ]; then echo "Inadyn stopped succesfully." else echo "Error stopping Inadyn" fi else echo "Inadyn is already stopped." fi else echo "Inadyn is already stopped." fi ;; reload|restart) $0 stop $0 start ;; *) echo "Usage: $0 start|stop|restart|reload" exit 1 esac exit 0
ln -s /etc/init.d/inadyn /etc/rc2.d/S03inadyn ln -s /etc/init.d/inadyn /etc/rc0.d/K03inadyn
Then you can use:
service inadyn start
