    Permission denied with Truecrypt

    hi,

    the problem:
    [oli@lucy resources]$ chmod -v 777 SearchEye.png
    Modus von „SearchEye.png“ nach 0777 (rwxrwxrwx) geändert
    [oli@lucy resources]$ ls -lah SearchEye.png
    -rwx------. 1 oli oli 2,0K 2. Jun 12:47 SearchEye.png
    [oli@lucy resources]$ cat SearchEye.png
    cat: SearchEye.png: Keine Berechtigung

    the device:
    /dev/mapper/truecrypt1 on /media/truecrypt1 type fuseblk (rw,allow_other,blksize=4096,default_permissions)

    Keine Berechtigung means permission denied

    Does anyone have a idea how this could happen or how i could fix it?

    the partition is mounted via truecrypt and i need read/write support because its a netbeans project which i have to compile

    edit:
    in the same directory:
    [oli@lucy resources]$ touch test
    [oli@lucy resources]$ ls -lah test
    -rwx------. 1 oli oli 0 13. Jun 18:06 test
    [oli@lucy resources]$ chmod 777 test
    [oli@lucy resources]$ cat test

    Re: Permission denied with Truecrypt

    I don't know how to solve your permission problem with truecrypt.
    But i hit the same problem, so I installed Realcrypt from the repos which is based on Truecrypt and it solved my problem.

    Re: Permission denied with Truecrypt

    OK. I think I know what your problem is.
    If you have already created an encrypted file with Truecrypt, Realcrypt won't open it.
    Basically you have to start again with realcrypt.
    What i did was go into my ubuntu partition, unencrypt the file and save it as a normal file.
    Then I copied it across to Fedora, created a new encrypted file with realcrypt, and dropped in the copied file.
    All worked fine.

    Posts #7 & 13 should solve your issue


    Here are some notes that I put together for realcrypt.

    Re: Permission denied with Truecrypt

    thanks for your response
    i dont think that is "childish", i have to work with my pc and this does not mean to study linux administration

    i used the same options as you in your attached graphic, but its ignoring the uid/gid
    also, there is no option to choose the mount directory

    edit: when i try it via command line:
    [root@lucy oli]# realcrypt -t --mount --filesystem=ntfs /dev/mapper/realcrypt1 /media/realcrypt1/ --mount-options=uid=500,gid=500
    Error: Unknown option: uid=500

    Try the "mount at directory" option (it's above the mount options.).

    Re: Permission denied with Truecrypt

    i cant find it :/
    http://www.imagebanana.com/view/gy2txe0/snapshot1.png

    edit: i must enter the root password on realcrypt startup, so i think its already running as root
    and when i run it in the console as root i get the same result

    edit #2
    i get it mounted with realcrypt -t --mount --filesystem=ntfs /dev/sda4 /media/realcrypt1/ --fs-options="uid=500,gid=500"
    but the options are still ignored when i look at it with mount

    I don't think truecrypt has a bug tracker

    http://www.truecrypt.org/

    As the problem exists in the base truecrypt package I would just close any rpmfusion bug reports as "Won't Fix" .

    Re: Permission denied with Truecrypt

    i dont think its only a truecrypt bug, because in ubuntu its working fine (i dont know if there is a "mount to dir" option but it get mounted "correctly" [maybe they set uid/gid automaticly?])
    is there anything else i can do to get it working?

    According to this site there isn't a ubuntu package (so they haven't patched it).

    https://help.ubuntu.com/community/TrueCrypt

    TrueCrypt is not currently available in the repositories for various reasons (possibly licensing). However, it is opensource and free for you to use. You need to download it from:
