Cannot see All the Ubuntu User files

ANewSon · December 5, 2010, 6:01pm

Hello openSuSe Friends

Here are the facts and problem :

Can see ALL the root files “/” of Ubuntu mounted partition in openSuSe 11.3
But CANNOT see ALL the files inside the user “human” folder in the mounted Ubuntu partition
Can only see these files inside the user “human” in the mounted Ubuntu partition

linux-ictb:/srv/www # ll -a /Ubuntu/home/human/
total 12
dr-xr-xr-x 3 human vboxusers 4096 2010-10-29 14:09 .

Is using & having these system :

openSuSe 11.3
Triple boot of Ubuntu, openSuSe, Windows 7


linux-ictb:/srv/www # df -h

Anymore that need to included ? If yes, please tell.

Any ideas of on what is the cause(s) of this effect ?

Thanks a lot, openSuSe Friends

Again, thanks please_try_again, I had tried your commands again

please_try_again · December 5, 2010, 6:57pm

Just wondering why the primary group of user human is vboxusers. That doesn’t look right. vboxusers should normally be a secondary group (so wouldn’t show up in this output).

Are you running this command as root? If not, try with sudo.
If you need to follow symlinks you can use the option L :

sudo find -L /Ubuntu/home/human -ls

ANewSon · December 5, 2010, 7:36pm

Hello

Wondering the same too.

Those commands were executed in {openSuSe Konsole and logged into “su” root mode.}

Right now, replying using Ubuntu operating system. Here are the commands executed in Ubuntu.


human@Ubuntu:~$ ls /home/human/
boot     Documents  examples.desktop  Notes     Public  Templates   Videos
Desktop  Downloads  Music             Pictures  script  Ubuntu One  workspace

Suppose to see these above folders in openSuSe.

human@Ubuntu:~$ cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=10.10
DISTRIB_CODENAME=maverick
DISTRIB_DESCRIPTION="Ubuntu 10.10"

human@Ubuntu:~$ uname -a
Linux Ubuntu 2.6.35-23-generic #41-Ubuntu SMP Wed Nov 24 10:18:49 UTC 2010 i686 GNU/Linux

Will get back to openSuSe right now to execute that one.

Wondering, is openSuSe (non-debian) is also using sudo ?! Gonna try that out, though.

Thanks a lot, please_try_again (, a cute username)

Those are clearly not the same folder. You should execute mount under Ubuntu and under openSUSE and post the output.

Looks like is an encryption issue ?!
Just for the info, the Ubuntu partition is mounted as /Ubuntu in openSuSe root “/”
When I had the *** Kubuntu *** installed, open up the rekonq > the rekonq then prompted the password > password was entered > every files in human folder of Ubuntu can be seen, is it an authentication issue ?!

Hmn, only the user human folder seems to be different, other root folder are the same.

Here are the verifications

You’re not mounting your Ubuntu partition under openSUSE but a different one. Replace sda4 with sdb4 in /etc/fstab on openSUSE.

ANewSon · December 5, 2010, 10:13pm

Replace sda4 with sdb4 in /etc/fstab on openSUSE.

the /etc/fstab file shown is NOT in DEVICE NAME, instead it’s in DEVICE ID form
Hitachi/something-something/asdfhshshf-part-1

However I remount Ubuntu partition again, by going Yast > “System” at left panel > “Partitioner” at right panel > remount the Ubuntu partition again by setting the fstab option to use DEVICE NAME instead, finally the ubuntu device name in /etc/fstab change to
/dev/sda4

But I believe that will not work if changing /dev/sda4 to /dev/sdb4 because the /dev directory has
/dev/sda1
/dev/sda2
/dev/sda3
/dev/sda4
… and so on
and only have one of type “sdb” that is,
/dev/sdb

However, I still change /dev/sda4 to /dev/sdb4

And the result ?! I’m now in Windows 7 Professional, because I can no longer boot into openSuSe, the /etc/fstab configuration is wrong. openSuSe cannot verify the drive correctly…something like that, so it can no longer startup. I have to learn how to use vi to edit the /etc/fstab and change back to /dev/sda4
D*mn, why do I keep forgetting the vi command ?!

My Ubuntu now is also broken, the Gnome is not showing, because I follow this tutorial to delete human user password
Linux: Delete user password because I believe it is an authentication and encryption of the human home folder issue. It’s to do with “encryptfs”

The two commands showing the Apache Web directory, those are my own created project files, NOT the linux system files. Those 2 commands showing the existence of same folders content, that confirmed that the Ubuntu drive was mounted correctly in openSuSe.

Thanks a lot, please_try_again, I’m please to hear your solution again.

Thanks

please_try_again · December 5, 2010, 11:33pm

Yep. You can mount by disk ID, UUID, Label or device name. Mounting by device names is not a good idea but, as it didn’t require further explanation … I personally mount by UUIDS. You can read the UUIDs for all devices by simply typing the command: blkid. That would have helped too.

Just a silly question (that I should have asked before): how many HDs do you have?

Yep it comes to the same.

Your assumption was correct … but I couldn’t see that you didn’t have that device from a distance.

That wasn’t good (under these circumstances).

Yes. OpenSUSE, Fedora and other Linux distros should learn how to handle such errors. Ubuntu normally ignores missing devices and wrong entries in /etc/fstab, as long as they are not needed, while Unix asks for confirmation before proceeding.

Can you not mount /dev/sda5 in Ubuntu?

sudo mount -t ext4 /dev/sda5 /mnt
sudo gedit /mnt/etc/fstab

Or boot from a Live CD ?

Or even use such a command:

cp /etc/fstab /etc/fstab.bad 
sed 's|sdb4|sda4|' /etc/fstab.bad > /etc/fstab

That wasn’t my fault.

I never uses encrypted filesystems, so I don’t know. But I guess that’s probably the cause of all your troubles.

please_try_again · December 5, 2010, 11:42pm

Yes. But don’t use ll. It’s not a command, it’s an alias. It could produce diffferent results under different OS (as you might have noticed from your example). Use ls -la if it comes to compare outputs.

You can run **blkid /dev/sda4 **under openSUSE and blkid /dev/sdb4 under Ubuntu to see if they are the same device … or is /dev/sdb4 just a faked device generated by the encryption. I have no idea.

jpugh · December 6, 2010, 2:20pm

The issue is obvious from a previous comment. The user HUMAN has encrypted it’s home directory and the key material is not available to the opensuse user. Gather your key material and unencrypt the directory via opensuse and you will see all of your content.

jpugh · December 6, 2010, 2:22pm

This directory is encrypted. Use the key material for user human and unencrypt it when you mount it in opensuse.

ANewSon · December 6, 2010, 9:42pm

Thanks to please_try_again and jpugh

I will try to solve that later, cause now am having another problem with my web server Problem seems endless, I have just installed openSuSe 3-5 days ago and used it for the very first time and I’m in love with it, because of many things like Yast, KDE programs and many many more. However, those days and until today I have been just solving problems & problems, have not started doing my work yet…
Those problems are quite commonly faced

Windows 7 conquered the MBR and causes openSuSe cannot be boot in, but luckily it’s already solved.
Another one is that the keyboard Fn key does not work for certain key like adjusting the brightness, and I have to wear sunglasses literally because the screen was in maximum brightness, luckily it was already solved too

But overall, I love openSuSe and I love Ubuntu and I love Windows 7, all of them have their own advantages and disadvantages. They complete each other.

Thanks
