This is on a Galaxy Note w/ICS and rooted. "/dev/fuse" exists, and "losetup -f" indicates "/dev/block/loop0" is free.

The Note has Android "full disk ecnryption" turned on - which gives an output from 'mount' of:

Create a test Truecrypt volume, e.g. 'test.tc' on a PC using the default settings, and format it with FAT. Then copy it to the Android device (e.g. in /sdcard).

Attempt to mount it with:

"

mkdir /sdcard/mnt

/data/data/csh.cryptonite/truecrypt /sdcard/test.tc /sdcard/mnt

% Enter password for /sdcard/test.tc: xxxxx Enter keyfile [none]: Protect hidden volume (if any)? (y=Yes/n=No) [No]: Error: Failed to create a file or directory in a temporary directory.

Please make sure that the temporary directory exists, its security permissions allow you to access it, and there is sufficient disk space: /sdcard/Android/data/csh.cryptonite/.truecrypt_aux_mnt256 "

The above was done from a Quicksshd session - hence the full path to truecrytpt being used (when this works I'll probably add it to the shell's path - or script it).

Should have also said - this is the stock ICS ROM from Samsung.

If I create the missing directory - the truecrypt command completes sucessfully - and I can mount the container:

" df | grep /sdcard/mnt /mnt/sdcard/mnt 31M 75K 31M 1024 "

I don't know if I did or didn't do something to cause that directory to get created - or whether it's in a different place because of the full disk encryption?

That's a bug in l.54 of https://code.google.com/p/cryptonite/source/browse/tc/tc-android.patch : The application directory is hardcoded to /sdcard/Android/data/csh.cryptonite, which doesn't seem to be the right place on your phone. Possible fixes:

Find out what the correct location on your phone is, and use that in case /sdcard/Android/data/csh.cryptonite fails. What's the location that's flashing up when you select "Use external storage" in the Cryptonite preferences menu?
Get the correct external application directory from C. No idea how to do that (see https://developer.android.com/reference/android/content/Context.html#getExternalFilesDir(java.lang.String) for the Java version).
Find out what the correct location on your phone is, and use that in case /sdcard/Android/data/csh.cryptonite fails. What's the location that's flashing up when you select "Use external storage" in the Cryptonite preferences menu?
Use the TMPDIR environment variable, as does the original truecrypt code. Supposedly there must have been some problem when I first tested it, otherwise I wouldn't have edited the original truecrypt code. Maybe it was a permissions problem.
- Write the external application directory to some string with the Cryptonite app and read this string from the truecrypt C code.

The location that flashes up when I select 'Use external storage' is:

/mnt/sdcard/Android/data/csh.cryptonite/cache

Thanks for reporting, the "cache" subdirectory might explain the bug. Will try to fix this in the near future.

It happens me too with KUbuntu 12.04 in a regular PC. This is the exact error message:

Failed to create a file or directory in a temporary directory.

Please make sure that the temporary directory exists, its security permissions allow you to access it, and there is sufficient disk space: /tmp/.truecrypt_aux_mnt256

@sanete: do you mean that it happens when you use the Linux version of truecrypt?

Yes, but other computers I have with the same operating system work ok. Surely it is some misconfiguration.

After rebooting, it works now!

So how can i change default path to your truecrypt TMPDIR to use it on internal sdcard? thanks!

From burnacc0...@gmail.com on December 12, 2013 13:39:47

do I understand correctly that, if the TMPDIR variable is set, it should use that instead of flash card ?

if so, it's just a matter of figuring one's way around the pains of setting variables ( http://stackoverflow.com/questions/3736062/how-to-set-and-use-an-environment-variable-in-android-test )

question to Christoph: why not use /cache as the resting place for TC's temp files?

ps sorry for doublepost. emails being public is not very comfy (Ukraine issues, I have them ;) )
