HFS, HFS+ and DMG's [Solved]

[teryaki]

I am trying to load up a dmg file in sabayon linux. Before I did anything I wanted to make sure it would handle the hfs or hfs+ filesystem the dmg would expand into so i did this...

Code: Select all

sudo modprobe hfsplus

and got

FATAL: Module hfsplus not found.

I also tried this with hfs, squashfs, ect. Obviously, Sabayon has no hfs support whatsoever. My first inclination was to

Code: Select all

sudo apt-get hfsplus

but to my dismay Sabayon has no apt-get

So I dug and dug through the forums and I found a kernel module that is supposed to do this, hfsplus.o.

Code: Select all

insmod Desktop/hfsplus.o

returns

insmod: error inserting 'Desktop/hfsplus.o': -1 Invalid module format


when I do a

Code: Select all

grep hfs /proc/filesystems

it returns

squashfs
hfsplus
hfs

What am I missing here?

Okay apparently DMG's are some compressed version of an hfs or hfs+ filesystem. Upon running

Code: Select all

mount -t hfs -o loop Desktop/mydmg.dmg /mnt/disk

I get

wrong fs type, bad option, bad superblock on /dev/loop/0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

Same result with

Code: Select all

mount -t hfsplus -o loop Desktop/mydmg.dmg /mnt/disk

Any suggestions?

Maybe this will help: http://viaforensics.com/computer-forens ... linux.html

P.S. dmg2img isn't in entroypy, but it is in portage.

Code: Select all

#emerge dmg2img

Code: Select all

!!! Couldn't download 'download.pl?dmg2img-1.6.tar.gz'. Aborting.
 * Fetch failed for 'sys-fs/dmg2img-1.6'

Hrm...it failed for some reason. Anyway I was able to download dmg2img from another source but I think I have to make and install the program. How do I do that?

Nevermind, I figured it out. THANKS!!

Allright...

DMG does not always translate into HFS or HFS+. I learned this lesson the hard way, which as it happens, is apparently the best way

Some DMG's are compressed, and connot be mounted in the traditional style, for example

Code: Select all

mount -t hfs -o loop myImage.dmg /myfolder

or

Code: Select all

mount -t hfsplus -o loop myImage.dmg /myfolder

sometimes will not work.

To remedy this, we'll install wine, which will allow us to run windows programs on linux, then, use a regular old windows ISO program to extract our information.

Look down on the bottom left of your screen. Theres a big blue button there with a "K" on it, kinda like a "start" button..click it. Now hover your mouse on the part there on the bottom that says "applications". Now move your mouse up to "system" and click it. The menu will slide to the left and you'll want to find "Terminal"; go ahead and give that a click.

Now you have a new window that resembles a "dos" box with a cool little flashing cursor, urging you to begin typing, and thats exactly what your going to do. Type this...

Code: Select all

sudo equo install wine

Password? Type it in. hit enter. you'll get...

WOOHOO! Now we will be able to install windows programs(that read DMG's) on our Sabayon installation.

Right after a restart.

Done it yet? Good.

Now fire up Firefox or any old web browser of your choice, and navigate to...

Code: Select all

http://www.ezbsystems.com/ultraiso/download.htm

Download and install ultraiso. Just like on windows. When the program finishes downloading, double-click the installer icon (uiso9_pe.exe) and it will install. That easy. Just like windows....did I already say that?

Now click the ultraiso icon on your desktop, click "continue to try", click file, go down to open,and locate your target DMG file.

Now, not only do you have a way to open (and work with) your DMG file, but you can install and use (almost) any windows program!
