Is there a way for my home folder to not be automatically mounted when i log in? And for that matter a way to change the password from my log in password to something else?

View 9 Replies View RelatedI chose the option to encrypt my home folder during installation, but I don't want it encrypted anymore since that makes it impossible to access any files in my home folder unless I'm logged in as that user.
I'm really hoping to avoid reinstalling from scratch just to fix this. Anyone know how to do it?
BTW, it's Ubuntu Server 11.04 32-bit.
How can I make Debian encrypt and decrypt my home folder when I log in/out like Ubuntu does?

encfs: preserve timestamps on a shared encrypted folder?
I would like to create an encrypted folder which can be shared by users included in the users group.To do so I used encfs:
Code:
cd somewhere
sudo mkdir encrypted visible
sudo chown root:users encrypted visible
sudo chmod 770 encrypted visible
encfs /somewhere/encrypted /somewhere/visible -o allow_other -o umask='007' -o uid='0'
Now if a user (included in users) creates a new document in the visible folder, that will be
Quote:
-rwxrwx--- 1 root users 0 2010-03-02 14:19 new file
While I would like it to be
Quote:
-rwxrwx--- 1 user users 0 2010-03-02 14:19 new file
Mounting encfs without the option uid='0' gives same results with only difference that instead of root the owner is the user who mounted encfs. Also copying a file owned by different user rather than root goes to the same: for example having in my home a file like
Quote:
-rwxr-x--- 1 me users 0 2010-03-02 14:30 myfile
and trying to copy it to the encrypted shared folder with
Code:
sudo cp -a -v ~/myfile /somewhere/visible
will give something like
Quote:
cp: failed to preserve ownership for `~/myfile': Operation not permitted
And the copied file on the shared encrypted folder will be as usual:
Quote:
-rwxrwx--- 1 root users 0 2010-03-02 14:30 myfile
Is there a way to mount encfs in order to preserve ownership?
lets say I install Ubuntu 10.10 on my laptop. I check the box that says encrypt my home directory, and my password is a randomly generated 10 character password using uppercase and lowercase letters and numbers. The next day my laptop gets stolen or something. How hard would it be for someone to decrypt the home directory if that were the goal?

When I begin typing in the terminal and press tab it does not autocomplete, and typing the directory manually says that there is no such file or directory, even though when I type dir or ls they are clearly there.
View 7 Replies View RelatedI have an NFS share hosted at a file server for several machines. I set up an encfs encrypted file tree in this. First, I created a directory in the NFS mounted tree where I wanted the encrypted files to be store (/home/nfs/phil/private). Second, I created a mount point where I wanted to access those files in the clear view (/home/phil/nfs-phil-private). Third I mounted encfs with the simple command "encfs /home/nfs/phil/private /phil/nfs-phil-private". During this mounting, it asked me for a pass phrase to encrypt the files with. Fourth, I copied some files into "/phil/nfs-phil-private". I saw that files with cryptic names were created in "/home/nfs/phil/private", along with a file named ".encfs6.xml".
That was on one machine named "lorentz". Then I switched to another machine named "euler". I created the same mount point here (/home/phil/nfs-phil-private). I verified that /home/nfs/phil/private already existed, as did "/home/nfs/phil/private.encfs6.xml". So I tried the same "encfs /home/nfs/phil/private /phil/nfs-phil-private" command. This time it failed. Here is all the output up to the first prompt:
Code:
15:05:23 (FileUtils.cpp:375) Archive exception: stream error
15:05:23 (FileUtils.cpp:326) Found config file /home/nfs/phil/private/.encfs6.xml, but failed to load
Creating new encrypted volume.
[code]....
The first two lines certainly appear to be some kind of error. I can cat the .encfs6.xml files just fine, so I do have permission to read it. It had not even prompted me for a password, yet. Anyone know what the deadl with this is? A possible cause is that the first encfs is version 1.6.1 (ubuntu 10.10 packaged as 1.6.1-1) and the second encfs is version 1.5.2 (ubuntu 9.10 packaged as 1.5.2-1).
I've been trying to share a folder with samba. This folder is the decrypted version of an encfs encrypted folder. Mounting the decrypted folder on the server is done automatically on login using gnome-encfs. Exposing the folder locally works like a charm. Now where I get stuck is trying to access the samba share from a client (even with smbclient on the server itself). I can see the share with smbclient -L:
tijm64@tijm64-HTPC:~$ smbclient -L 192.168.1.100
Enter tijm64's password:
Domain=[TIJM64] OS=[Unix] Server=[Samba 3.4.7]

View 2 Replies View RelatedI could not find details of what CryptKeeper was doing and I worked this out. It shows how to open and close CryptKeeper files using encfs form the command line. I hope this helps others.
Ubuntu karmic 9.10. CryptKeeper 0.9.4-1 encfs 0.5.2-1ubuntu1 also works in Mint8. Tom Morton author of CryptKeeper site: [url]
How Gnome Cryptkeeper works with encfs
In CryptKeeper create a new encrypted folder:
The directory above is created and also another hidden one called: /home/ian/.aaaaaaxxxxTestCryptKeeper_encfs which contains one hidden file called .encfs6.xml. As you create additional folder and files in the /home/ian/aaaaaaxxxxTestCryptKeeper additional folders and files with encrypted names are created in /home/ian/aaaaaaxxxxTestCryptKeeper 4L9KBI4IeoAKOoZ,IwzVyn2VPGysXt-JCbStUej5Ewnn90. These mirror any files and folders which you create in the encrypted directory except that there names and contents are totally encrypted.
The above CryptKeeper directory can be created anywhere within the Linux file system, for example, on another partition. In each case two directories are created within the parent (in this example /home/ian/), one with the original directory name, the other preceeded with a "." and followed by "_encfs".
How to open a directory created with CryptKeeper using encfs.
Provided you copy the directory like .aaaaaaxxxxTestCryptKeeper_encfs and all its contents, it can be opened anywhere using the following command. (Note that full path names are needed.)
encfs /home/ian/.aaaaaaxxxxTestCryptKeeper_encfs /home/ian/aaaaaaxxxxTestCryptKeeper
The mount command will then show:
If /home/ian/.aaaaaaxxxxTestCryptKeeper_encfs does not exist you will asked if you wish to create it and you will be asked for a password twice. In this case it will not be in CryptKeeper unless you then import it.)
If it is a CryptKeeper file then it appears in CryptKeeper file list as opened and can be closed from there. To close from the command line type:
Note unmount will not work for these files.
Set up a few machines yesterday to test out some parallel code. Just for fun, I selected the "encrypt users files" option when setting up Ubuntu (10.10). I had never used the option in years past. Now I'm finding it a pain. EG., ssh requires me to already have a login to the machine before it will let me log in w/o a password (eg., using id_rsa.pub and authorized_keys).
Similarly, I have no reason to encrypt files on these machines. They're just crunching numbers. Is there an easy way to disable this? Or do I need to delete my original user and make another one (with all the su privelages, etc...) w/o an encrypted file system / home directory.
I was messing around with fed 12 yesterday (only on a test installation) and i've hit a snag. I installed openbox and tint2, nitrogen, obconf etc so i could have a #!-style session at startup. It all worked fine until i installed pcmanfm and removed nautilus. The problem is that i can't display files in my home directory, either using pcmanfm, a reinstalled nautilus, or in terminals. Every time i try to point a file brower there it just seems to get stuck searching forever, until i kill it. Weirdly in terminator i can do an 'ls' to see visible files, but 'ls -la' causes the problem again.
ps i thought permissions might have something to do with it, so i did a 'chmod -R 777' as root. it changed permissions for quite a lot of the files but then froze again, and now the problem persists.
I have just installed Ubuntu Jaunty (I do not like Karmic, please don't try to make me upgrade) and after installing all my programs I realized I did not encrypt my home directory.
I know it's very simple to do this during the installation but I can't seem to find an option to do it after it.
Is there a way to do this?
I just installed 9.10 on my laptop and selected the option for home folder encryption. I am running DropBox and placed the DropBox folder on my desktop (meaning it should be encrypted when I am logged out.) So I have two questions:
1) Shouldn't this setup cause my DropBox files on the server to be encrypted? Apparently they are not because they appear as unencrypted text using the DropBox Web interface.
2) If they were encrypted on the server (which doesn't appear to be the case right now), how would it be possible to share them with another client unless the encryption on both clients were set up identically?
When I installed, I selected the option to encrypt my home folder. I believe this is causing constant crashes now, since error message is user id/password related. Is there a way to remove the encryption?
View 5 Replies View RelatedLet's begin from the top. I have a relatively new laptop that I've been running Ubuntu on (along with a little-used Windows boot). Picked it up in November or so, installed the current "latest" version of Ubuntu at the time (9.10). I have been doing incremental upgrades, and it's been progressively breaking down more and more. Yes, this includes 10.04.
After GRUB stopped working, I decided it was time to try a reinstall from the top. I told it to leave all the other operating systems alone and do a full reinstall.
Fortunately, I had managed to stuff most of my current work in duplicate locations during this whole debacle, somehow. Don't ask me how I managed to do that when GRUB wasn't working. However, when I installed, I conscientiously said "Oh, yes, Ubuntu, encrypt my home folder! I love privacy!" As a result, about... 30 gigabytes of useful (but ultimately re-downloadable) material is rather inaccessible at the moment. When I try to boot the old system using the newly fixed GRUB, it goes into kernel panic. This seems like a no-go.
I have a saved hojillion-character long passphrase for decryption from my install back in November. Conscientiously saved in the case of just such an emergency.
I read this how-to and followed it to the letter as far as I could tell, trying to mount with ecrytfs to recover my data.
[USERNAME] here is a proxy for my actual username. Yes, the location of my old home folder may seem a little bizarre.
Code:
sudo mount -t ecryptfs /media/c82ca9fe-2b15-4aca-a98d-6482b1d80a32/home/[USERNAME]/ /home/[USERNAME]/oldhome
Passphrase:
Select cipher:
1) aes: blocksize = 16; min keysize = 16; max keysize = 32 (not loaded)

How to secure the Home folder. I forgot what the script was?
Something like chmod 0700 $HOME. Is that right? I'm just not sure.
When installing the latest Distro of Mint (I believe this is not much different, if at all, from Ubuntu as far as this goes) I chose to have my Home folder encrypted using the login password. This was a function of the installation. What I was wondering about was how secure this was and if I should maybe use something to do a better encryption or not.

View 1 Replies View Relatedlast week I decided to not just run dist-upgrade, but give the Lynx a completely fresh install. Before that I've only copied my home folder to an external hard-drive.
Now that I'm on Ubuntu 10.04 I have no clue how to import my old personal key and the passwords from the backup (my old home folder).
Lately, I've found 2-3 times an .exe file with a random name in my /home, and another data file with a random name as well. I'm a user of wine, but none of the programs that I use seems to be the cause. Last time it happened I sent it to virustotal.com, and this is the result: [URL].. So, this is clearly a virus. The two files show "nobody" in the proprietary field and "none" as group. What can I do to track down the cause? Also, telepathy-butterfly likes to hog 100% of CPU lately, and all I can do is killing it: is someone exploiting a vulnerability? if so, why the hell would he drop a win32 virus?
View 9 Replies View RelatedI would like to give a few students a preconfigured Ubuntu USB stick with certain apps. I also encrypted the home folder in case of loss.
With TrueCrypt, cloning an encrypted container would be a big no-no because any one could just backup their header with a known pw and use it to decrypt anyone else's container due to each container using the same master key. I assumes the same applies to home folder encryption, yes?
Is there a way, other than creating a new user with home folder encryption, of forcing a master key change?
while since I've been here. I'm having an issue with a fresh install of 11.04. Due to work requirements, I encrypted my home folder, which is fine, however, it seems to randomly lock itself down while I'm working, and it's getting really annoying.
Apps stop working, I can't open nautilus (something about not being able to create certain folders because home is locked), hell, even the terminal link on my desktop says failed to launch application (though the launcher on the top panel works). I just have to run ecryptfs-mount-private and enter my password to fix it, but it's doing this every 15 minutes or so. what might cause it to relock itself so frequently? I would expect to not have to deal with mounting my private data, that should happen at login and be good until log out.
