I used ecryptfs on a Private directory. It has about 5GB of data, but no matter what I do I can't free space in there. I have tried to delete some GBs to no avail. System monitor still shows me 5GB.
View 3 RepliesI'm getting "Low Disk Space" warnings in Ubuntu 10.04, because of eCryptfs, which somehow manages to eat up twice as much disk space as an unencrypted partition normally would.When I click "Examine" this is the picture that I see:(the blurred out part is my username of course)Why is this happening?And most importantly, what can I do about it?Does Ubuntu expect me to buy twice as much disk space just to encrypt it?!

And another problem is that it is showing 0 byte free space istaed of freeing the space. it may seems that both problems are dependent on each other.
Had this problem in a few different instances where a process was creating a set of files in directory and using those files.
Some one just happened to go to the dir and deleted those files without stopping the process. The result being that as the process is still telling the machine that the disk usage is still what it initially was (df -h shows the old disk usage) , where as a du -h or a ls -lh on that same dir show that the files are not there.
Once this happened with mysql where the user delete the database dir in /var/database_name in the mysql home dir. The result being that the dusk usage was still showing as the old one even if the files were missing. This was resolved by restarting the mysql server.
Similar thing happened with some other processes where on restarting the problem was resolved..
My question being is there a method to solve this problem by whithout restarting the concerned process.. Some magical command like free disk or recheck dis usage :-) .. may be too much to ask but can some one help me out here.
I have connected an another hard disk to my computer and mounted its drives. when I delete the files from second hard disk it is not increasing the free space. only 1.3 GB is left on that drive of second hard disk.

which is approximately HALF the space than actually needed. Is this increase due to ecryptfs? Also I noticed that the hidden folders are not shown. Are the hidden files within the shown folders included in this list? How do I show a summary which includes the hidden files?
On a fresh karmic install, I have a user account with ecryptfs enabled home directory. I want that directory to be secured when I log out.
I have two administrator accounts, user1 and user2. I log in as user1 (with ssh, will test regular logins tomorrow), /home/user1/.Private gets mounted to /home/user1, everything is fine. I log out.
I log in as user2, and /home/user1/.Private is indeed unmounted. But I can do
Code:
sudo su - user1
which will ask me for the password of user2, and then I am logged in as user1, /home/user1/.Private is again mounted, without ever typing the password of user1.
On the other hand if I invoke

After a disastrous upgrade to 10.04 I am at my wits end trying to recover my /home partition from my unbootable system. The /home partition is part of a RAID5 array across 4 disks and I've been trying to use some disk imaging tools from Ultimate Boot CD to recover it with, but none of the utilities seem to recognize or will let me work with my multi-disk device.
Currently I've been booting up with a Live CD in attempts to mount the encrypted partition then copy all the files to an external device I bought, but the mounting process has presented me with some problems. The partition in encrypted with ecryptfs and I have both the disk's passphrase as well as an FNEK signature to work with. Attempting the following:
Code:
Another small issue is the cipher I used. I don't remember which kind of encryption the disk is encrypted with (80% sure it's aes though). I assume figuring out which cipher I used will be more like a guessing game through the ecryptfs mount prompt, but I'm wondering if this would affect the error message I get.
if it's possible to use a white or blacklist to control which folders are ecryptfs encrypted when you're using the "encrypted home folder" option.
Of course I can always create an extra folder outside of my ~ and then symlink what I don't want encrypted into it, but I'd rather that it's possible to create like, ~/.ecryptsfs/excludelist with a list of paths that shouldn't be encrypted.
When I installed the system I went ahead and added the private/ecryptfs feature. However, I have never actively (or at least "awaringly") used it. I don't know if it is being used passively or if it contains any of my important data that I cannot already otherwise access.
There is also a problem with space constantly reducing. I'm losing HDD space and I'm not aware of what is causing it. I've tried clearing caches, tmp, things like that, disabling internet, not running applications that would tend to eat at the hard drives. But no luck. And the space free is being very weird. A few days ago I had 700M remaining on my "/" partition (it's a 19G (almost 20G) partition), then a day later I had several gigs free but I did nothing, then another day later it was back to 800M or 700M free. Something very fishy is going on here.
Regardless, my focus on this thread is that dang ".ecryptfs". Can I get rid of it *without* losing data? Disk usage analyzer, partition with a little over 19G: /home is using 20G ...somehow... (and on a 19G partition?!) weird. The main user account home is using 9.7G ...the ".ecryptfs" is using 10.2G. I really do not want that 10.2G to be used just for the sake of some shady ecrypt feature.
I recently installed 32bit maverick and wanted to make it login automatically. I tried enabling auto login from Admin > Login but that didnt work and I was still prompted for my password. Then I went to Users & Groups and changed the password option to Do Not ask for password at login now after I reboot, the user list is shown (only 1 user) and it doesnt ask for password after I click on my username.
However, then it gives a few errors (as i vaguely recall):
1. cannot load .ICE directory in my home directory
2. some error 256 about a gconf-sanity-2 file
3. nautilus cannot load my home directory etc
and then it gets stuck without loading anything (blank wallpaper). i ve tried navigating to my home directory using Alt F2, gksudo nautilus and my home dir contents are encrypted by the ecryptfs (there is a readme.txt file and a shortcut). i have tried to decrypt but it doesnt work... i ve also tried to start/stop gdm, and startx but nothing works. if i stop gdm, then the prompt doesnt recognize my password and keeps on rejecting the commands i enter... I think this has something to do with the home dir not being decrypted due to the dont ask for paswd option... how can i disable the dont ask for pwd without the gui (i can access my / by booting through an external usb).
I have a laptop with an original linux Suse Enterprise 11 OS, and a Windows 7 installed after, I'm a beginner in Linux and actually I need some disk space, so I gonna free the linux one, so two partitions should be wiped, the ext and the swap, and that will provide enough space for my purpose, my questions is the follow: I'll be using Gparted to format, does not this make any issue or conflict with windows 7? I have a partition of the Suse System Recovery (to conserve of course), if I have formatted the partition where the Suse was installed, are there any risk to lose (crush) other partitions? If I want to install (recover) my Suse after freeing spaces (two disks) using my System Recovery CD, (again ^^) are there any risk to lose (crush) other partitions?

A question of ODBC correctness - maybe someone knows.
Code:
// statement handle is sth, connection handle is dbch
SQLExecDirect(sth, ...);
// ... bind var, fetch results ...
SQLFreeHandle(SQL_HANDLE_STMT, sth); // free statement handle
SQLEndTran(SQLHANDLE_DBC, dbch, SQL_COMMIT);
(error checking removed for clarity).
To my mind this seems wrong - surely the statement handle should be free'd only after the commit is done? Or maybe not. I theorize about the ODBC library like this: a whole set of statements can be created, run, executed in one transaction (which is held at the connection level), and only after all that is a commit/rollback done. So maybe it's OK. Even so it still feels weird. What is written above works, but there are rare and very difficult to replicate problems with this code, and I wonder if a premature free might be the cause...?
I recently had to install ubuntu 10.10 through wubi because my olde ubuntu broke after a failed upgrade. Now I am quite happy with everything in 10.10 except I can't get to the files in my olde home folder because I chose the home folder encryption option in the installation process. How can I recover my home folder? They all seemed to be recovering from another user not another partition.

Ubuntu 10.04 LTS Ran some updates,finally got around to rebooting. When I rebooted, It came up with Some errors about missing files. Came to discover my home directory was not decrypted. I simply had a readme file that said to run "encryptfs-mount-private". When I do it doesn't tell me the passphrase is incorrect, it tells me
Code:
Inserted auth tok with sig [xxxxxxxxxx] into the user session keyring You do not own that encrypted directory and I do own it. If I put in a different pass it tells me it's incorrect, I'm logging in fine, but my home directory is remaining encrypted.
I have a fresh install of Kubuntu 11.04 and I already have the lastest ecryptfs-utils installed. I have the ".Private" folder but not the "Private" folder.
When I try to set it up I get this error:

ERROR: wrapped-passphrase file already exists, use --force to overwrite.
How do I get my "Private" folder to appear? I don't think I should just be throwing my stuff into ".Private" and I don't want to have to see all the hidden folders all the time either. Should I use the --force argument, and what would that do?
Logical Memory Space of 4GB is divided in to 3GB User Space and 1GB Kernel Space. Always. Correct?
1. How can we change it? (just changing value of PAGE_OFFSET is okay?)
2. If system have only 256MB of memory (embedded system) and suppose Kernel Modules eat away all the memory during boot. User space will be left will no memory. Is this case possible?
When I reinstalled ubuntu I chose to encrypt my home folder (something that i've never done before) but now that I know it doesn't really make a difference i'd like to decrypt it because the .encryptfs folder is taking up so much space i'm getting notifications every time I log in.

As part of making a encrypted private folder i told encfs to encrypt swap space on my pc knowing that this would probably break sleep and hibernation. That said i just turned on ubuntu for 5 mins, had to go away for a bit, when i came back to unlock the screen my password was not being accepted, and another 5 mins later the screen said that my session had timed out-i had to do a cold reboot Does this mean i cant lock the screen anymore?
View 7 Replies View RelatedMy workplace recently switched to Active Directory for our netdisk space (I work at a University in the US). The "only way" (recommended) by our IT department is to use a cifs protocol. I've had absolutely no luck with that at all. However, it turns out that there is secure WebDAV protocol setup which works well on campus. If I'm off campus I have to connect via a VPN connection; our school uses Cisco Anyconnect 2.3.0254. It works well for me to connect to a printer, etc on campus.
Here's my problem: I can't connect to my netdisk space from off-campus using the Secure WebDAV bookmark that was working oncampus, even when I am connected via the VPN connection. I am using UFW. Is there a port I need to open up, or am I missing something else?
After years with debian stable I'm testing debian...testing (stretch) in a separate partition. I'm just using the stretch repositories and nothing else, so that I won't mess up the system by pulling packages from different branches.
Unfortunately ecryptfs-utils is not (yet) available on stretch. Is there any safe way to use this package on my debian stretch, preferably the stable package from jessie?
How long it will take for this package to reach stretch from unstable?
Right, I seem to get very random system crashes. My machine will stay up for long periods of time, or sometimes only a few mins, also it doesn't seem related to just using a particular program. As you can imagine this is leading to a bag of woes. After reading on a forum about logs I went to /var/log and in the system log found the following entry . . .
"Jan 10 18:46:10 jon-desktop kernel: [ 92.718896] Either the lower file is not in a valid eCryptfs format, or the key could not be retrieved. Plaintext passthrough mode is not enabled; returning -EIO"
This is repeated multiple times and having checked after a few crashes seems to be the central problem. Being specific about the crashes, they freeze the entire system. Can't ctl-alt-del and sound loops, have to hard reset. I have a feeling that when I first installed Ubuntu 9.10 I selected to use an encrypted file system but have a feeling that I didn't set it up correctly. Not sure exactly what I didn't do but I seem to remember it was to do with generating a passphrase. So . . .
1) What is this error from my logs?
2) Is it linked to me not setting up the encrypted filesystem correctly?
3) Is there a way to check the settings / sort them out properly?
4) Is there documentation for my dullard state which can aid me in this, or is it quite simple?
I have an ecryptfs partition on a usb drive, system runs Debian squeezeWhat I'd like to have is that when I connect the drive it will be auto. mounted and I'lleither have to enter the passphrase or it will already be in the keyring (even better).It seems ecryptfs can auto-mount a directory but I want to auto-mount an entire encryptd partition. Is this possible?.Also, can I have another encrypted directory, say ~/Private, at the same time or can ecryptfs handle only one at a time?
