Hi to all,
first of all many thanks to the author of this great software.
I have a problem that for me is very urgent and important.
I admit that i don't know if it's my fault, a bug in some other piece of
software, or a bug of encfs.
I wanted to reinstall my notebook.
I have several crypted directories, named for example:
/root/.lavorocrypt
that i mount with a script as:
/root/lavoro
with the usual command "encfs /root/.lavorocrypt/ /root/lavoro".
I made a backup of my entire /root folder (my home), paying attention
that crypted directories were not mounted at backup time.
To make the backup i used a plain and simple "tar cvfz backup.tar.gz /root".
I reinstalled my notebook with a brand new slackware 13.
I decompressed the archive in a subdirectory of my "new" home, called
/root/oldroot/
Now, when i try to mount the old crypted directory, encfs does not
recognize it as a crypted directory and prompt me to create a new
encrypted filesystem. When I saw this, i was frightened... but my
crypted files are always there, so I hope there is some way of
decrypting them.
Now to what I could make wrong:
1) Previous / partition was formatted ext3, now I use ext4
--> but I think that encoding is not related to filesystem... anyway, i
tried to restore it also on a ext3 filesystem, same results
2) When I "untar" the archive I get some warnings:
tar: Ignoring unknown extended header keyword `SCHILY.dev'
tar: Ignoring unknown extended header keyword `SCHILY.ino'
tar: Ignoring unknown extended header keyword `SCHILY.nlink'
--> but all my other data (photo, mp3, downloads, firefox addons...) are
ok - and my previous distro was a slackware-current, so i think
not-so-different...
3) My previous kernel version was 2.6.30-something, and now i have a
2.6.29-6 (default slackware 13 kernel)
--> but i cant imagine how this could impact encfs decryption...
Maybe in SHILY.ino there is some info related to inode that is important
for encfs? I don't know, even I don't know why i get those warnings...
4) I noticed that in the restored crypt directory there is not a .xml
file describing the encfs encoding. So i created a new crypted directory
(same, default, options), i took the .encfs6.xml attached to this email
and copied to the decompressed encrypted directory. This time mounting
went well, but the mounted directory was empty... but I think that the
"salt/seed" could be different, so I do not think is exactly the same
thing, sadly...
Any ideas?
Reading again the email, it's perhaps more clear that it is not an encfs
bug... but I don't know where to start to solve my problem.
Thank you very much for the help you could provide.
Best regards
Daniele
