Manual encrypted persistance file mount in Knoppix 7
 
I need to manualy mount my KNOPPIX-DATA.aes to any point that i can access
Mainly its to fix somethings that makes it unloadable
In bad case just to take my files
Amount of console work doesnt matter ^^

Hi,

Knoppix is a good choice, Finnix anf TTYLinux as well, but, that's besides the point... :)

Steps I use

-insert the CDRom and a USB stick
-(re)start the system
-issue fdisk -l after "login"
-find the designation of the drives to be mounted
-issue mkdir /media/hd and mkdir /media/stick
-issue mount /dev/[drive] /media/hd (example mount /dev/sda1 /media/hd)
-issue mount /dev/[stick] /media/stick (example mount /dev/sdb1 /media/stick)
-issue mc (midnight commander, yes, that's still in there ;) )
-save the files

snag....if the system is encrypted, I think you'll have a problem...I rarely encrypt systems, unless I have a rock-steady backup plan...

good luck

I just wanna reboot knoppix with no persistance
Go root
Make Dir at /mnt/data
And mount it there

I have it encrypted but i need this data

Thor_2.0 10-07-2012 05:31 AM

No sweat...you've got the angles covered. This is the best way to go. Good luck. Just survived a sys-wide crash myself, still licking my wounds...

Oh, edit, to go root, issue this command in the shell

nothing more. Knoppix doesn't need a password, it's in run level 2 anyway.
It will present a menu, item 11 is the one you want, select it, and follow (something like) this

Quote:

su -
fdisk -l
mkdir /mnt/data
mount /dev/sda?? /mnt/data
cd /mnt/data
use fdisk to know the designation of the drive. you may have to use media instead:

Quote:

mount /dev/sda1 /media/data
...but the result is the same...

I dont say i need to access my hard drive or what ever
I dont need to save my system on my harddrive

I used knoppix as my main distro for long time
I have all my stuff in the persistance file
Its encrypted, i wanna enter my password and mount it to some dir

Thor_2.0 10-08-2012 02:02 AM

Same principle, same idea, same MO...believe me, you've got it covered.
Since you've got the password (I hope) the encryption shouldn't be a hurdle. I suspect the persistence file is on a stick somewhere...that means sticking it in the PC and mounting it. To find out WHAT to mount, issue fdisk -l after inserting the stick...then mount whatever you've got to your favourite folder...

Lemme (and all of us) know how this turns out... :)

root@Microknoppix:/mnt# mount /mnt-system/multiboot/knoppix/KNOPPIX/knoppix-data.aes /mnt/data
mount: you must specify the filesystem type

I think you dont understand that i have a usb and i got a file that is virtual device, and this device is encrypted

Its file not actual device

Yes, THAT was a "detail"... :)

try this (with everything plugged in)

Quote:

fdisk -l
als look at what that reports back as filesystem type, when in doubt, issue this:

Quote:

man fdisk
and go for the section that lists the filesystem types, remount with the -t option supplied:

mount -t [reported type] /mnt-system/multiboot/knoppix/KNOPPIX/knoppix-data.aes /mnt/data[/QUOTE]

I marked the extra bits for you...

The encryption, that will be a problem, though...

As a question of curiosity: how did you get to using Knoppix as a day to day OS? It's not really meant to be used like this, it's a rescue system...and a very good one at that. Is Knoppix the OS running? Eg : did you start the PC with it? The mount path seems strange...when I mount something, this is roughly what U do:

Quote:

su -
fdisk -l
mount /dev/sdX /media
That, with the Knoppix in the drive and nothing else, Knoppix is the runnign OS...

And what i should mount from this?

I came to knoppix as main os several times when i didnt have os yet, or when windows didnt wanna boot

I reboot in knoppix, make persistance, try to fix windows or install gentoo, i fail, i start using knoppix as main os, it gets bigger

manualy mount KNOPPIX-DATA.aes to any point
 
Try the following steps

(associate loop device)
# echo 'yourpassword' | losetup -e aes -p 0 /dev/loop6 /path/to/knoppix-data.aes
(Now you can use /dev/loop6)
# mount /dev/loop6 /where/you/want/to/mount/it

Once you are done,
(unmount)
# umount /dev/loop6
(destroy the loop device association of knoppix-data.aes)
# losetup -d /dev/loop6
