Convert binary file to csv and then back to the binary format
Hello *nix specialists,
Im working for a non profit organisation in Germany to transport DSL over WLAN to people in areas without no DSL. We are using Linksys WRT 54 router with DD-WRT firmware There are at the moment over 180 router running but we have to change some settings next time. So my idea is, to use the firmware modification kit. After decompressing the original firmware, I get a file calling defaults.bin (inside the attaced file) in which are stored all variables with the correspondending values. I have no informations about the binary format but maybe it would help to take a look in to the C-source: (inside the attaced file)
I think at the end of the code is a function to read the parameters.
Okay back tot the topic.
I want to convert the defaults.bin into a csv text file. Then a script reads from a database the required parameters like IP address, username, password ... and change so the csv file. Then a script should make from the csv file a new (specially for one router) defaults.bin file. At the end, the firmaware modification kit compress all to the firmware file what we can send to each router.

REGCONVERT(1) The Regina Handbook REGCONVERT(1)NAME
regconvert - Convert between different Regina file formats
SYNOPSIS
regconvert [ -x | -u | -b ] old-file [ new-file ]
DESCRIPTION
Between Regina versions 2.4 and 3.0, the data files changed from using an impenetrable and undocumented binary format to using (optionally
compressed) XML.
This utility converts back and forth between these different file formats.
The argument old-file should be the file to read and convert; the argument new-file should be the name of the new converted file to write.
These two filenames may be the same, in which case the old file will be replaced with the new.
If the argument new-file is missing then the new file will be written to standard output, which forces the output to be uncompressed XML
(see option -u).
Warning: When writing an old-style binary file, some information might be lost. Old-style binary files can only store information
that was understood by the old version Regina 2.4.
OPTIONS -x (default)
Convert to compressed XML.
-u Convert to plain (uncompressed) XML.
-b Convert to the old-style binary format.
