Well I'd try to just change all 5 occurrences of 192.168.7.x with some other subnet and see if it works. Or are you asking how to edit the binary config.bin file? I work on OSX so all the utilities I need are already there, so I just wrote a simple, quick little script (it should work on any Linux system as well as OSX) to make it easier (most of the code is just to provide the command line options
):
dlinkconf.sh:
code:#!/bin/bash
declare PROG=${0##*/}
declare BIN_FILE=""
declare XML_FILE=""
declare HDR_FILE=""
declare ZIP_FILE=""
declare MAGIC_NUM=""
declare -i PACK=0

NAME:
${PROG} -- Pack/unpack a DLink router config.xml file to/from a config.bin file.
SYNOPSIS:
${PROG} -{m|h|x} <BinFilePath>
${PROG} -p <XmlFilePath> -M <Magicnumber> -H <HeaderFilePath> -b <BinFilePath>
DESCRIPTION:
Extracts either the magic number, header or embedded xml config file to stdout.
Compresses a xml file and packs it into a bin file using the supplied magic number
and header.
OPTIONS:
Extract:
-m <BinFilePath>
Extract magic number from bin file.
Example: '-m config.bin'
Will output the 32-bit magic number in hexadecimal.
-h <BinFilePath>
Extract header from bin file.
Example: '-h config.bin > header.txt'
Will output the header, converting nulls to newlines.
-x <BinFilePath>
Extract xml from bin file.
Example: '-x config.bin > config.xml'
Will decompress and output the embedded gzip archive.
Pack:
-p <XmlFilePath>
Gzip and pack the xml file using the supplied magic number and header.
-M <MagicNumber>
The magic number to use for the bin file.
-H <HeaderFilePath>
Path to the header file to insert into the bin file
-b <BinFilePath>
Path to the bin file to create.
Example: '-p config.xml -M 5ea3a417 -H header.txt -b config.bin'
Will create config.gz and pack it into config.bin.
