Salut,
voilà le script complet qui me permet d'updater mon ip vers dyndns via 
ez-ipupdate :


Here's a noob friendly How-To for setting up ez-ipupdate on a networked 
machine behind a cable/dsl router (where the router is the actual device 
where the IP changes).

This document assumes you have ez-ipupdate already installed and ready 
to go, with a config file of /etc/ez-ipupdate.conf.
The scripts used in this How-To are based on scripts submited by 
philliptemple and REM_simone, also in this thread.
The scipts have been modified to be more resource friendly and to only 
call ez-ipupdate when your IP actually changes.

Create a file called dns_update in /usr/local/bin with the following 
content:

#!/bin/bash

wget --quiet -O - http://checkip.dyndns.org | awk '{print $6}' | sed -e 
's/<\/body><\/html>.*//' > /tmp/new_ip

if [ -n "`cat /tmp/new_ip`" ]
then
  if [ -n "`diff --brief /tmp/old_ip /tmp/new_ip`" ]
  then
    ez-ipupdate --address `cat /tmp/new_ip` -c /etc/ez-ipupdate.conf
  fi
fi

cp -f /tmp/new_ip /tmp/old_ip
# end of file

Then make sure the script is executable with this command:

chmod 755 dns_update

This script uses a web page at dyndns.org to get your current IP and 
saves the results to file.
If the file is not empty and the IP doesn't match what it was the last 
time the script was run, ez-ipupdate is executed.

Before running this script the first time, you should create an empty 
'old_ip' file in /tmp so an error is not reported.
You can do that with the following command:

cat /dev/null > /tmp/old_ip


To get this script to run every ten minutes, execute the following 
command to set up a cron job:

crontab -e

Then enter the following line and save the file (:x)

0-59/10 * * * * /usr/local/bin/dns_update


C'est un peu long, désolé, mais je voulais être sûr de ne rien oublier.
Merci de votre aide !
