[SOLVED] Installed TrueCrypt but unable to write into

[michel]

Greetings,

I managed to install TrueCrypt with various sudoers edits and now the program is installed and will open the encrypted folder but I canot copy TO the folder.

Any ideas why not?

If you don't provide any more information noone can tell

Please at least show the output of

Code: Select all

mount

and

Code: Select all

ls -la /path/to/truecrypt/mountpoint

Code: Select all

[michel@localhost ~]$ mount

truecrypt on /tmp/.truecrypt_aux_mnt1 type fuse.truecrypt (rw,nosuid,nodev,relatime,user_id=0,group_id=0,allow_other)


Code: Select all

[michel@localhost ~]$ ls -la /path/to/truecrypt/mountpoint
ls: cannot access /path/to/truecrypt/mountpoint: No such file or directory

I think it is a permission issue but I do not know how to change permissions in mageia.

Michel

[michel]

The KDM add on alows me to run root commands and I managed to change permissions but I still cannot wrinte into the truecrypt folder.

Michel

[michel]

OK did it!

I changed the permissions of the external hard drive where my truecrypt folder is located but that did not resolve the issue. I then noticed that when I mount my truecrypt folder, an entry "truecrypt1" is created in the /media directory. I changed the ownership and permission and now I can write to my truecrypt folder.

[michel@localhost ~]$ ls -la /path/to/truecrypt/mountpoint
ls: cannot access /path/to/truecrypt/mountpoint: No such file or directory

/path/to/truecrypt/mountpoint is only a placeholder, you need to adapt this to your system. How should we know where you mount that thing?
I've not used truecrypt since ages, so from your output i don't really know where the unencrypted content is now mounted.

Please post the output of

Code: Select all

ls -al /tmp/.truecrypt_aux_mnt1

and

Code: Select all

ls -al /run/media/michel/624281e9-ba51-4c0e-9437-50bf54d2cf14

FWIW, the permissions you changed will probably only be effective until you reboot, you need to change the mounting itself.
For your current fstab entry for truecrypt, it shows in the options user_id=0,group_id=0 which makes the contents of that thing being owned by root (user id 0)

I rebooted many times and trucrypt1 entry is always in /media.

Code: Select all

[michel@localhost ~]$ ls -al /tmp/.truecrypt_aux_mnt1

Then please show the output of

Code: Select all

ls -al /media

And use code tags when posting output etc. :ftp://ftp.mandrivauser.de/rpm/rpm/extra/test/code_tags.ogv

This is what I get BEFORE launching truecrypt and AFTER I launch it

Code: Select all

And use code tags when posting output etc.: ftp://ftp.mandrivauser.de/rpm/rpm/extra/test/code_tags.ogv

I've fixed it in your previous post (again), please use them next time.

Now when you have launched truecrypt, please post the output of

Code: Select all

ls -al /media/truecrypt*

But altogether this sounds like something which should be changed by some setting in truecrypt itself, and not to be manually adjusted afterwards.

[michel]

The command lists the content of my folder.

[doktor5000]

So post the output here, at least for the .. and . "directory" entries, so we can see the current permissions.
As an example, here's mine for an external drive:

[doktor5000@Mageia2 ~]$ ls -al /media/EXTERN3
total 80
drwx------ 1 doktor5000 doktor5000 4096 Aug 26 18:58 ./
drwxr-xr-x 8 root root 4096 Aug 26 22:00 ../

This shows that the top directory of that NTFS partition is owned by my user and group.
