OpenSUSE Install :: Mounting Encrypted Partitions As User Not Root?
Mar 21, 2011
there is a way to mount, encrypted partitions as a normal user and not as root so that i may copy files into it using the file manager itself? even in the case of normal partitions other than /home, i can't seem add any data in them. the mount points i used are seperate directories within the /home partition?? also, is there a way to create partitions in such a way that it can be accessed, just as how windows partitions are accessed in linux?

I'm having a problem mounting a vfat partition using fstab... If I don't use fstab and mount it manually, everything works fine. But if I add a line to fstab, it will mount, but will have root permission only - so I can't write to it. can mount another partition (ext4) through fstab and everything works fine. Just not sure why there's a problem with the vfat partion. Also, if after mounting it through fstab I try to unmount it, it gives an error saying only root can unmonut it.

I have an encrypted partition which shows up in Dolphin file browser.But as a non-root user, I cannot unlock and mount it. A message in Dolphin comes up saying that a policy prohibits this. As root, this unlocking of the encrypted partition goes normally. I cannot find the setting to change in KDE perhaps;

I've created some encrypted partitions using Disk Utility, and would like them to be automatically mounted when Ubuntu starts up. Is there a guide to this anywhere?
I've gathered that it involves /etc/crypttab and possibly /etc/init.d/cryptdisks, but haven't had much success so far.
Ideally, some of the partitions would mount early in the boot process, while some of them can mount after I've logged in.

I just updated a system to Fedora 12. It has the same partition setup as the previous Fedora 11, but now when booting it pauses with a padlock icon next to a text entry box.I'm assuming it's trying to get my password to mount the encrypted partitions I have on the drive.
However, most of the time when I'm using that computer, I don't want those partitions mounted, and I would prefer to do a luksOpen/mount manually during those times I need the data thereon. Is there a way to get plymouth to ignore those encrypted partitions while it's booting, so that bootup doesn't pause for user input? I have an empty /etc/crypttab and the partitions in question are not in /etc/fstab.
For anyone who's looking at this, pass "rd_NO_LUKS" on the command line to disable the initrd from looking for encrypted partitions to try to mount.

I haven't used encryption previously but through that for better security, I would enable it on one of my disks. I went though the process and when done, copied data to the device etc. My house had a powercut the other day and I noticed that the device did not mount automatically upon restart. Unfortunately, I have forgotten the de-cryption password and have lost access to my data. Is there a way of either recovering my password or getting the partition to mount without the password so I can access the data, copy/back up and then re-create the partition without encryption?

When i use the "Places" menu to try to access the other partitions on the same hard-drive i get a pop-up box asking me for the Root user password. Is there any way to mount it without? The normal user is now in the sudoers group but really i don't think i should be asked for authentication at all?

I have a dual boot system with OpenSUSE 11.3 and Windows XP. I would like to have OpenSUSE mount the windows drives (C,D,E) only when one particular user logs in, and not be accessible for the other users. I have tried playing with the fstab options (do not mount at startup + user can mount, creating a new user group 'mounters' and replacing the 'users' in th the fstab line with 'mounters' etc.) but this is not doing what I want.

I'm having some problems with a hosted openSUSE 11.2 server. It was running fine until I did a "zypper up" to apply patches. This included a kernel update.
On reboot the root partition does not mount the / partition giving the following error:
Unrecognized mount option "defaults.noatime", or missing value mount: wrong fs type, bad option, bad superblock on /dev/md2.
Through an Ubuntu rescue disk (this is what Hetzner provides) the disk can be mounted without problems.
( I installed a fresh openSUSE 11.2 with a similar configuration and got the same results after the update)
The server is a hosted installation from Hetzner in Germany with just the basics for LAMP setup.
The disk setup is as follows using software raid1:
swap /dev/md0 (/dev/sda1 /dev/sdb1)
/boot /dev/md1 (/dev/sda2 /dev/sdb2)
/ /dev/md2 (/dev/sda3 /dev/sdb3)

I can see from /var/log/messages error messages and weird crashes that the disk in my laptop is on the way out. I plan to replace it but to do this I'd rather not have to install everything again.My laptop has these partitions:Windows Recovery (10GB)Windows 7 (NTFS 96.6GB)Linux /boot (ext4 100MB)Linux LVM (encrypted, 143GB)I need software that will allow me to create an image (or images) of all these partitions, save the image(s) to a USB hard drive and restore from those images once I've put the new, blank, hard drive into the laptop. Does anyone know of software (either open source or commercial pay-ware) or a technique to do this?

Is there a way that I can get Dolphin to mount partitions? When I try to, it gives me an error on the bottom of the window saying I don't have permission to. I also can't mount partitions in other programs like Amarok, because of the same issue.
Error Message:
An error occurred while accessing 'Windows 7', the system responded: org.freedesktop.Hal.Device.PermissionDeniedByPolicy: org.freeDesktop.hal.storage.mount-fixed auth_admin_keep_always <-- (action, result)

this is a strange one. running 11.2 pae 32 bit kernel with all the most recent updates and gnome. This is a fresh install. I built the machine, and then installed all my repositories and software, and used the machine for about 2 days, and now when I log in it hangs on logging into gnome. it's strange because the wireless notification about available wireless networks is in the top left corner of the screen, and nothing else happens. I can log in as root.I also had this issue before I formatted the machine (that's why I formatted)

The error message I keep getting during mounting is:-
device-mapper: remove ioctl failed: Device or resource busy
This is from ane external USB HDD I use as a backup device. I've tried formatting it as ext4 ane encrypting it from the command line
# mkfs.ext4 /dev/sdc1
# cryptestup luksFormat /dev/sdc1
which run without errors but an attempt to mount throws up the above error as well as saying - you must specify the file type (tried that) - and fails to mount. I've tried using YaST to format and encrypt it which throws up the same error when I run mount but actually does actually mount the filesystem Googling around has brought up info saying that it's probably a race condition brought on by invalid udev rules. I've got a (mostly) working system and the udev rules documentation leaves more confused than when I started.

I need to run a script (which requires root privileges) on login per-user only. I want this to runtomatically so I'll add an appropriate line to .profile.A couple of questions:1 The easiest way I can think of to run the script as root is to setuid, but I know there are security concerns. Is there a better way

I've got a somewhat anemic box, resource-wise, set up in the office where any authorized user plus a guest account can log on. Guest is tightly restricted, but we get a lot of people passing through who need one-time or occasional access - this isn't the big problem. What's causing me problems is that a user will log in, walk away or go to the john and the screen locks. Next user (or this one comes back) and winds up doing another login. At the end of a week or so, I may have a couple of dozen sessions listed when I ask for "users". Since some of these session contain open applications they eat up an awful lot of a marginal amount of available memory. How do I kill the entire session (as root) for a user? Gotta be simple but it's not obvious to me.

I came across this issue today and it changes everything I know about file permissions in linux. I created the following files in my system :
Code:
/tmp> ls -lad /tmp/testperm/
drwx------ 2 sagi users 4096 Apr 12 20:23 /tmp/testperm/
/tmp> ls -lad /tmp/testperm/file.txt
-rw------- 1 sagi users 12 Apr 12 20:23 /tmp/testperm/file.txt
[code]....
One more thing, as you can see I also set that only the owner of the directory (which is me again) can read and cd (the execute bit) to the directory. how come user 'root' can read the content of the file ?
Code:
# id
uid=0(root) gid=0(root) groups=0(root)
# cat /tmp/testperm/file.txt
Hello world

My install of 11.4 has been running perfectly for for several weeks now. But- (always a but) today it started acting up. I cannot log in to any user account including Root after logging out. After a cold boot I can log in again anywhere but after logging out I have to reboot again then I can get back in to any account once. After logging out any attempted log in causes the splash screen to blank for a few seconds and then it comes back with the previous successful user name log in but typing in the password blanks the screen a few seconds again. Clicking on a user account also blanks the screen a few seconds and then it again comes back with the previous log in users name.

I installed the HPLips printer driver for my HP Officejet Pro 8500 Printer.
The driver often stops printing on its own (HP Device Manager => "Printer Control" tab shows "stopped"). I guess it does so when it encounters a situation where it cannot print right on.
The problem: Users without root permission cannot restart printing, even when everything is o.k.. They have to call me in order to "start printer", because restarting it needs root access.
Does anyone know how to solve the problem: either setting the driver not to turn to "stopped" or permitting a restart by normal users?

I like to do a minimal install, and then run some of my own scripts to install the rest of the packages I need, so to keep a lean system. When installing F14 with a partitioning scheme as follows:
Code:
/boot - 500MB
LVM
- swap - 2048 MB
- / - 15GB
- /home - Rest of file system - Encrypted
Everything works fine and the encryption works with no problem. However, as a friend pointed out to me, if you partition as follows:
Code:
/boot - 100MB/ - Rest of filesystem - Encrypted You are not able to boot the system when doing a minimal install. Meaning: you get up to the point to where you need to enter your password to decrypt the filesystem, and then nothing but..., well, nothing. However, and here it gets interesting, if you use the same partition layout, and you install the "Graphical Desktop", everything works fine. As I can not understand why this happens, I am currently testing a partition setup like so:
Code:
/boot - 100MB
LVM - Encrypted
- / - Rest of filesystem
Just to see if that works.
Anyhow: to make a long story short: It seems that the minimal install "forgets" to add some packages which are needed to decrypt the filesystem. Does anyone know which package this could be or why this occurs, so it can be added as part of the minimal install?

Background information: I need to install WinXP on my computer to use Spectraview II software for monitor profiling. Tried it under Wine, didn't work...thought about virtualization, but Graeme Gill (creator of Argyll) said that probably wouldn't work:
Quote: The problem is that emulators often don't implement hardware details properly or at all. There's no standard way on Linux to read/write the DDC, so there is no surprise that wine doesn't emulate MSWin's API's for this. It's doubtful that any of the VM's do either. USB can be an issue too, and some instruments may not work in an emulated environment. I already had Ubuntu 10.10 installed, so thought I'd try installing WinXP after, then recovering the MBR. Lots of headache.

I'm a long time user of Debian, but I'm having trouble with my partitioning process. Here is where I currently stand:
I am installing the latest Wheezy build. I am trying to install debian with an encrypted LVM that spans two hard disks.
My partitioning layout is as:
1. /home
2. /root
3. swap
4. /boot
I then added partitions 1, 2 and 3 to a physical volume group. I then took that physical volume group and added it to a logical volume. Then I encrypted the logical volume, leaving the /boot partition untouched. I was under the assumption that the only partition the system needed free to reach the loading of the LVM is the /boot partition, as it holds the files necessary for booting. But when I attempt to finalize the disk, it gives an error stating, "No root file system detected". That would be an issue as it is currently sitting inside the encrypted LV. Am I wrong in including the root partition in the encrypted LV?
What is the best way of having as little of my file system non-encrypted as possible while still allowing a proper boot?

I have vista and opensuse 11.2 on my computer, the problem is i can't open ext3 partitions from vista but i can the other way. I tried Ext2fsd but the linux partition is always in a read only mood even when i change this option. Also, all folders are empty I downloaded the program as admin and compatable with XP SP2.

Prelude: OpenSUSE 11.2 (2.6.31.8-0.1-desktop), installed Novell client 2.0 SP2 (novell-client-2.0-sp2-sle11-i586.iso).
I found that if any usual user is logged into a NDS-tree, then _local_ root has full access to user's network shares, including the user's home directory located on remote Netware-server. Is it by design or
have I missed something? Nevertheless in windows local admin has no access to network resources mounted of any other user. If you runas shell (as admin) then admin in principle can't "see" network shares which were mounted (connected) by other users - they are accessible ("visible") per session.

Q: How can I allow my users to mount a cifs share without an entry in fstab in OpenSuse 11.4?
I have an answer myself. Until OpenSuse 11.2 I could mount my samba shares by making mount.cifs and umount.cifs setuid root. Today I installed OpenSuse 11.4. Unfortunately mount.cifs isn't anymore allowed to be setuid due to security concerns. Security is not an issue in my case, so I copied the mount.cifs and umount.cifs from 11.2 to make it work again:
1. Download cifs-mount-3.4.2-1.1.3.1.x86_64.rpm from this repository (I use 64 bit):
"http://download.opensuse.org/distribution/11.2/repo/oss/suse/x86_64/"
2. Extract the files mount.cifs and umount.cifs from the rpm and copy them to /sbin
3. Make them setuid root:
Code:
linux-y5qw:~ # chmod u+s /sbin/mount.cifs
linux-y5qw:~ # chmod u+s /sbin/umount.cifs
4. Mount your cifs shares as a normal user:
Code:
martin@linux-y5qw:~> /sbin/mount.cifs //192.168.2.2/data /home/martin/data/ -ousername=martin

OpenSuse 11.2 64bit When I select a hard drive in Dolphin file manager it asks for the root password. I would like to gain easier access to the drives. The Yast Partition Manager lists all of the drives and has a dialog box to change this i.e. user can mount the drive. Can we change this feature on the run, while the system is running ? The Fstab file is not listing all of the drives, so I cannot just edit the config here.

Just the last day or so, I've noticed a long pause when I boot my laptop, with lots of disk activity. dmesg says:
[Code]...
Why would there be a 15-second pause (during which the disk is slammed) between mounting root and mounting swap? During this time I see nothing but a blank purple screen, there are no cycling dots or text scroll. Is this normal and I'm just freaking out over nothing because there's no indicator of progress? GRUB default boot options: quiet splash nomodeset video=uvesafb:mode_option=1920x1200-24,mtrr=3,scroll=ywrap vt.handoff=7

I am installing Ubuntu on the same hard drive as Windows 7. The partitions of Windows 7 have already occupied the left part of the hard drive. From left to right, the Windows partitions are one partition for Windows booting, one for Windows OS and software installation, and one for data which is planned to mount on Ubuntu. I was wondering how to arrange the order of partitions of root, home and swap, i.e. which is on the left just besides one Windows partition, which is in the middle and which is on the far right?
