I have two computers on my network, both are running Ubuntu 10.10. I wish to access encfs-encrypted directories on a remote computer from my local computer. I used nfs to mount the remote encrypted directory onto my local machine, and then I used encfs to decrypt. But because of nfs' use of some UID-type ownership convention rather than user:group, I have no access to the directory I just mounted.I want my local machine's software to access the files, so ssh login is probably not a solution, and I would like to avoid using encfs' --public option if possible.
I 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).
Whenever I mount a encfs directory to a regular directory, the regular directory disappears. this is the command I use encfs ~/encrypted ~/plain When I try to access the folder from my windows computer, I can not see it. What to do?
There are some encfs folders with private data on the server and all data is exported via nfs to all other omputers in the house.I can mount the encfs folders on another computer (using encfs command) to work with the data, but I never dared to mount it on more than one computer simultaniously, because I fear the encrypted data might get corrupted if more than one computer mount and access it at the same time.
So I want to ask about your experience: Is it safe to mount an encfs folder on several computers at the same time? All computers use "hard" and "sync" as nfs mount options to minimize risks of data loss. But can I access the folders simultaniously, or do I risk corrupting the encfs encryption and lose everything?
my os is opensuse 11.4. I tried k-encfs, but failed. Running the .rpm file said successfully installed, but I cant find the program and running the 'install' script gives me another error message.
I am trying to get Encfs working on Ubuntu 10.10 with only partial success. I am using the Ubuntu package which is version 1.6.1. I am also trying to build 1.7.4 source on Ubuntu 10.10 which is failing.
First the problem with the Ubuntu package, which I realize may be fixed in 1.7.4. I am mounting a clear directory with the --reverse option to have an encrypted view of this data. This so far works, although I do not know if it really works correctly. I used rsync to copy all the encrypted data to a third directory outside of this first mounting. Then I do a second mounting (without --reverse) using that copy as the source, to make a mountpoint with a clear view of the copied encrypted files. This fails as no files show up at all.
I am doing it this way because my intended first use for Encfs is to copy an encrypted view of a local physically secured backup directory containing clear data to another remote machine where sometimes it is not physically secure. Transfer is by ssh over rsync, but that is not sufficient security for the remote machine. So the role of Encfs is to be sure the data is never in a clear state on that machine when the machine is not attended. This location is the home of the owner of the company who is not always at home. The machine is, in theory, at risk for theft when no one is at home (this is the risk we want to address). The owner will personally have the Encfs password, and may need access to some of these files. So it would be treated as an encrypted store and Encfs would be used to view it in the clear by manually mounting it that way (e.g. not with --reverse).
I am doing the test entirely on my desktop at the moment, as described above. I am using a script to carry out the entire setup of my tests, so it is fully reproducible, and that configuration can be incrementally changed as desired. I have a suspicion that certain messages resulting from the setup may indicate the problem. This is from the first mount with --reverse:
Code: Creating new encrypted volume. Standard configuration selected. --reverse specified, not using unique/chained IV Configuration finished. The filesystem to be created has the following properties:
I 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.)
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:
Right, just a quick question about rsnapshot over sshfs and encfs. I've set up an encfs filesystem, and when mounted on the remote machine remotely:
Code: touch foo.bar Code: cp -al foo.bar foo.car Works as one would expect it to.
The same is true on the local machine (The EncFS has External IV chaining disabled). However, when the remote dir is sshfs mounted on my computer here, and then encfs'd to a decrypt mount on my computer, I can move files to it, and they go over the network and get encrypted, however:
Code: cp -al <file> <file> No longer works, I get 'not implemented' errors...
I thought since I don't have External IV chaining this shouldn't be an issue - I've tried without any of the file chaining options, again to no effect. All work remotely, or with both locally, but not over sshfs. Is this a quirk of sshfs?
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.
Just a warning / question about Encfs on Slackware current. I doesn't work due to the upgrade to boost 1.4.2. I ran encfs on an old install of 13.0 to get at my data, but I'd prefer to access it right from current. A big warning: if you try to access your encrypted data on current it will corrupt your encfs6.xml file and I don't know if it is recoverable (I had a backup of mine).
I started up my machine this morning and entered my password to encfs as I do each day and was greeted with a message telling me my password was incorrect. I tried several times, checked caps lock but no joy.
The message (which I didn't copy and paste unfortunately) mentioned ssl and I remembered that openssl was one of the security patches I applied at the weekend. So I removepkg'd the two openssl packages (v0.9.8m) and then installpkg'd the original ones that came with slackware 13.0 (v0.9.8k).
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:
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?
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?
I have a Dell Inspiron 1720 running Ubuntu v10.04 with a wireless card.My desktop is a Dell Optiflex running WinXP.The desktop is connected via ethernet cable to a Linksys wireless router. Certain folders on the desktop are set for sharing. Up until early last week I was able to access the desktop folders from the laptop with no issues.Suddenly I am now getting this error "Unable to mount location Failed to mount Windows share" whenever I try to access the desktop folders from the laptop.I suspect an upgrade is the culprit, but not sure.
i'm trying to connect to the three other machines in my house but am having quite a hard time doing so. i've never had a problem in the past with ubuntu, but, with 9.1 and windows 7, things have gotten a bit harder. i'm running 9.1 and my roommates are running windows 7. i've installed, set up and configured samba and i can see the computers on my network, but any time i try to access either of the drives, it says unable to mount location: failed to mount windows share.
I have been trying to share folders from my main PC which is running Ubuntu 10.04. I have been able to figure out Samba enough to get my a couple of folders shared, but I have been unable to share any folders which are on my external harddrive. After entering the path in my smb.conf file they appear on the network but I am unable to navigate to them. When trying to navigate to them through the network folder on the pc they are actually connected to I get an "Unable to mount location: Failed to mount windows share" dialog box. On the windows pc I am trying to share with I get, "Windows cannot acces \Josh-Desktop ame of folder"
My smb.conf file looks like this:
That folders I cannot access are Music and Videos.
im trying to get a network setup i followed the instruction via gentoo wiki samba what i have done
[Code]...
then i did chmod 777 to the shared folders on both machines went into nautilus it sees the folder but it will not mount the folder showing the error msg:"unable to mount location failed to mount windows share" ive been searching unbuntu forums opensuseforums and google for an answer to this issue but as of right now anything that i have tried to do has failed and nothing seems to be working.
I have recently set up an ubuntu installation on an old PC. After some fiddling with both it, and the windows 7 machine, I have managed to share all of my drives. However, when attempting to access them from ubuntu, only 2 of the 4 hard disk shares will mount, with the other 2 failing with a Unable to mount location, failed to mount windows share error message.
Is there any open source virtual machine so i can study the source in order to create my own? i'm gonna write my own, so it doesNT matter if license does not allow further development of the code.
i am already a little bit familiar with linux and now i want to know better the linux OS. i have downloaded the source code of the krnel from the kernel.org and i dont understand the linux source trees organization, so can somebody do me a favor and give me a link to some internet page (or at least a book) that explains that?? i have searched in the internet with the tag:::linux source trees organization and i have not found nothing interesting
We all know we can install a linux system such as Fedora 10 and use it. Being linux, one should in principle get the source codes for everything that has been precompiled (except the proprietary drivers such as nvidia) in the installation DVDs/CDs. Where are the source codes ? Is there a place I can download them ? To avoid confusion, I am not referring to the kernel source that can be compiled to give a linux kernel, but that does not include the drivers, such as intel_drv.so.
To be more specific, the intel graphic i810 driver has been built into any linux system, but where is the exact source? One answer may be that primary source intellinuxgraphics.com. However, if anyone tries to download the every changing (i.e., keep updated almost every single day) driver source codes from freedesktop.org, it is almost certain that the source codes will not be the same as the one that is finalized in Fedora 10.
I have installed ubuntu 10.10 and the Samba addon to configure my shares to my Windows terminals.This is what I got
Firewall off (utf disabled)
Internal Sata /dev/sda1 (EXT4 FS)
External USB HDD /dev/sdb1 mounted at /media/SG1500GB (EXT4 FS)
I have two shares
1. //home/test - Which I can see and access with no problems (can't write to it though even though I set the share as writable?, but, I can read from it). This is available to everyone. My windows terminal can see this folder and access it. This is on my main 80GB internal drive /dev/sda1.
2. //media/SG1500GB/Music. I set this up for everyone full access and I can see it at all my Windows machines but,I can't get into the folder. Windows keeps giving me an error stating network path not found.I also try to access it via the Nautilus (Places/Network/system/music) and get an error message "unable to mount location, Failed to mount windows share". This drive is mounted per the disk utility.
I made an ip packet using raw sockets and used icmp header of echo request inside that ip packet.I have a wifi lan with 2 host(laptops) connected to it. when I send the packets to any of these host the reply me with echo reply as i see in wireshark. but when i change the source ip and mac to that of another host there is no echo reply packet in the network but only echo request packet is there. Can anybody tell me why is this happening. and am also using Promiscuous mode so non of the packet is discarding.
