truecrypt problem (shared folder) PROB SOLVED

[dot2dot]

hello,

config ubuntu > wintel guest
i have an external drive which is entirely encrypted.
on host i have to mount it using tc.
on vbox i map a shared dir which is sitting on the truecrypt volume.
boot up the guest.
map the drive.

i can see the dir - and write to it...
then after a moment i can't see a ton of dirs on the shared drive (panic sets in..)
(shutdown the guest..)

back in ubuntu i cant see anything in the truecrypt volume at all.

i go into the (truecrypt) gui - umount the volume.

then re mount it - restart my (now downed) guest

the file i created is gone.

-- so my question is - can i reliably use vbox with wintel guest - and truecrypted shared folder and write to it. ?

Only if the TC folder is shared via a real share.

excuse me what do you mean ?

When mounted on the Host, add a share to the folder you want to share and 'net use' it from the Guest.

hi,
I've finally attempted your suggested solution.
It failed.
I cannot view all contents nor edit / update files.
I then go back to the main os and the tc volume is confused - i have to umount then remount it.

I can only surmise from this that the process i'm attempting is not possible at this time either due to TC or VBOX.

Anyone have any other suggestions ..

Then your doing something weird, TC on a server, access TC container with passphrase, it gets assigned a drive letter, then share this drive letter with a sharename, from remote net use this sharename to a remote drive letter and of you go.

Don't use TC on a remote machine to access a TC container elsewhere unless the remote site is the only one using it.

Server,
TC -> decrypt container, drive letter assigned,
Open properties of drive letter and create share.

Remote,
Net use into share.

hey perhaps i am doing something weird. (if i am excuse me).

• i have an ubuntu server.
  external hd with one partition totally tc encrypted.
  start tc
  mount volume (which is the entire external hdd).
  go into vbox
  share out path - ie /tcvolume/x/y
  start vbox guest
  confirm shared drive using net use x: \\vboxsvr\x\y
  drive mounts fine.
  i view content - it contains not all of what I'd expect
  ok i then shutdown guest
  back into server view content of external drive - doesn't look at all correct
  umount tc vol / mount tv vol - all looks ok again.

now - on reviewing the above what appears to be incorrect ?
note tc version 6.1a / ubu 8.04 / vbox 2.2.2

go into vbox
share out path - ie /tcvolume/x/y

Wrong, use a real samba share, not a vbox shared folder.

ok set up two shares

1/ local is on my server hd - music
2/ server external hd (tc) - data

on the client i can see both shares

i map share #1 i can view everything (and create / delete).
i map share #2 - i can see nothing at all.

thoughts ?

[vbox4me2]

2) is this shared from visible data on the server?

ea. z:\server\TCvolume.tc -> data inside TC volume accessed on server as y:\
share set on Y:\

The share might disappear after reboot since TC needs to create Y: first.

hi the data on the external drive is the entire drive.
it is mounted via "mount device" - rather than "mount file".

once mounted as for eg /media/truecryptxx
i share out a dir therein

output of
smbclient -L //box -U me

- note as before
data is a tc DISK/PARTITION
music is local directory.

- oh and btw once i attempt this all access to 'data' becomes difficult i have to umount the tc and remount to gain access to 'data' again.

I have no idea how this works on a linux Host, on a windows Host this works as I've described, device or file.
On the Host you must be able to access the share locally, which works on windows, so when shared you share the same thing across the LAN. I think there is a chapter about this in TC's manual or online.

ok sussed it.

how it does work and how it should work are often two different things.

to enable this to work - the following process must be used - anything else and it will fail.

1/ the tc volume is on the whole partition - so do not do anything to it ubuntu - ie no mount.
2/ config pass through usb for the device in vbox
3/ boot vbox client
4/ the vbox will pick up the device
5/ start tc on the vbox client
6/ mount device
7/ all data avaliable - no problems.

-- see - easy. no shares / no shared folder no nothing - only a device

thanks for your help btw - i just thought about it and .. then well it became clear we'd missed a trick.
