Hello,

Just thought that I would share a way to automatically backup the current configuration of a running DSR-1000N that you have remote access to via Web-GUI.
Since I couldn't find any standard way to do this, i wrote my own PHP-script with CURL to login to the DSR and download the file.
You can find information on the DSR-1000N at: http://www.dlink.com.au/products/?pid=842.

Heres my script
--

<?php
/*
* This script is written by Robin Friberg (robin.friberg@gmail.com).
* It's free to use and modify as you want, I would like to be notified if you do any
* feature enhancements on the script (like adding another firmware support or such).
* For now the script supports configurationbackups of devices running firmware 1.04B13_WW.
*
* Database structure:
CREATE TABLE IF NOT EXISTS `enheter` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `addr` varchar(255) NOT NULL,
  `username` varchar(50) NOT NULL DEFAULT 'admin',
  `password` varchar(50) NOT NULL DEFAULT 'default',
  `lastbackup` date NOT NULL DEFAULT '0000-00-00',
  `version` varchar(30) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=latin1 ;
*
* Observe that the table isn't built for performance. Works great for me that backs up 40 units thou.
*
* This and other scripts might be found at my website: http://rm-rf.se

Save this to a file in your Linux-server and add a cronjob to run it, preferable every night.
You will have to populate the mysql-database with hostname, username and password for every unit you would like to backup.

Contact me if you have any problems or have any enhancements to the script.

Robin
