suggested feature in Xbian Config: update IP via a dynamic dns provider

[zilexa]

OK this is the solution. I still want to add a few other IP check services in case ipecho.net goes down. But for now it works perfectly. For reference if anyone else wants this:

Schedule this script to run every x hours, mine runs every 4 hours (type crontab -e in terminal and add this to the bottom):

Code:

0 */4 * * * sudo sh /etc/ipupdate/ipupdate.sh

the script, create a new textfile (sudo nano /etc/ipupdate/ipupdate.sh) and copy paste:

Code:

# this script will check if the current external IP address has been
# changed by your ISP internet provider. If so, it will update your
# subdomain (for example: mypc.freedns.org). This way, you will always
# be able to connect to your Raspberry when you are not at home and don't know
# the IP address of your home. Also handy if your ISP internet provider keeps changing your IP.

TOKEN="add your token from your freedns subdomain"

if test -f /etc/ipupdate/ipupdate.conf
then
CacheIP=$(cat /etc/ipupdate/ipupdate.conf)
fi

ExternIP=$(wget -qO- http://ipecho.net/plain)

if [ "$ExternIP" = "$CacheIP" ]
then
# Both IP are equal
echo "Update not required..."
else
# The IP has change
echo "Updating http://free.afraid.org with " $ExternIP
wget http://freedns.afraid.org/dynamic/update.php?$TOKEN -o /dev/null -O /dev/stdout
echo `date` "Updating log with IP " $ExternIP >> /var/log/dmesg
fi
sudo rm -f /etc/ipupdate/ipupdate.conf
sudo echo $ExternIP > /etc/ipupdate/ipupdate.conf
