Update your dyndns using wget

[LrdShaper]

For those whose router does not support dyndns like me. I've had this script on my NSLU2 running unslung firmware for years. i've tested the same script on the readynas just to see if it works and it does.
if you're having problems with the web ui like i am, this can be an alternative to using backup functionality to update dyndns
First you must already be running raidiator v4 and able to login as root via ssh.

open a file using vi

Code: Select all

vi foobar

and paste the ff code:

Code: Select all

#!/bin/bash
wget -q http://checkip.dyndns.com:8245/index.html --output-document=/var/tmp/new.ip
if [ "`cat /var/tmp/new.ip`" = "`cat /var/tmp/old.ip`" ]
   then echo;
   rm -f /var/tmp/new.ip
else wget -q http://USERNAME:PASSWORD@members.dyndns.org:8245/nic/update?hostname=YOURDYNDNS.ADDRESS.ORG --output-document=/var/tmp/upd.ip
   rm -f /var/tmp/old.ip /var/tmp/upd.ip
   mv /var/tmp/new.ip /var/tmp/old.ip
fi

replace
USERNAME = dyndns username
PASSWORD = dyndns password
YOURDYNDNS.ADDRESS.ORG = dyndns address (ie infrant.kicks-@$$.org)

make the script executable

Code: Select all

chmod 700 foobar

you may want to put the script in cron and have it run once a day. if you want it to run on boot-up place the script in /etc/init.d

the script was taken from http://www.nslu2-linux.org and not created by me. cheers!
