I understand at least some of the advantages of this multi-user set-up, but why would you have to become root to stick a DVD in the machine? I suppose I could go into root and chmod the mount command, but - why would it have been set up that way at all? Is it paranoia?

When I installed OpenSuse 11.2 it mounted I configured to mount all of my windows/NTFS partition. However, one problem is that only root can write to it. I was trying to change it to '777' permission. However, as root I can't change permission. chmod doesn't work and neither does using nautilus (as root) work.I even tried unmounting it and then doing a chmod. That didn't work either.
View 1 Replies View RelatedI recently installed a printer on my OpenSuse 11,2. Now every time i start the computer it prompts for the root password.
In the window that pops up it states
/opt/Xerox/PSULauncher: session followd by a long string of letters and numbers.
There is a script "uninstall.sh" in the PSULauncher directory that i ran but it didn't fix the problem.
The root user of Linux doesn't have permission to read/write a regular file, unless all users have permission to read/write this file, like below:
drwxrwsrwx ....... file_name
However the owner of the file can still read/write this file.
AND:
0) not the problem of execution, just read/write
1) not the problem of device because regular user can read/write it.
2) the result of command id:
uid=0(root) gid=0(root) groups=0(root)
so I don't think it's the problem of group.

View 1 Replies View Relatedwant to run VirtualBox with root permissions. Trouble is that only when run as root i can access attached USB devices inside of a virtual machine, otherwise, these a greyed out).Now running VirtualBox as a root user also changes the configuration folders, making all my virtual machines already defined disappear. I also don't want to copy all to the root configuration folders. Is there a way to give the VirtualBox root permissions but without actually running the application as a root user. Is it possible to do without changing the permissions of the non-root user, i.e. i don't want my user to have all root permissions, due to security considerations.

I just noticed on my Ubuntu machine (ext3 filesystem) that removing write permissions from a file does not keep root from writing to it. Is this a general rule of UNIX file permissions? Or specific to Ubuntu? Or a misconfiguration on my machine? Writing to the file fails (as expected) if I do this from my normal user account.Is this normal behavior?Is there a way to prevent root from accidentally writing to a file (Preferably using normal filesystem mechanisms, not AppArmor, etc.)
I understand that root has total control over the system and can, eg, change the permissions on any file.My question is whether currently set permissions are enforced on code running as root. The idea is the root user preventing her/himself from accidentally writing to a file. also understand that one should not be logged in as root for normal operations.
I logged in my system as root. but when i run a simple shell script i got an error like . Permission Denied. why m getting this error.

View 3 Replies View RelatedI have created a new file system (fuse) which works fine and is mounted in the local host. I want to be able to mount it from another host. I added it to /ect/exports: /mnt/ltfs *(rw,sync) And restarted nfs. Then from my client host I type:
mount -t nfs myHostName:/mnt/ltfs /mnt/data1
Where /mnt/ltfs is on my local host and /mnt/data1 is on the client host. Note that this is a "FUSE" file system so here is it's local "mount" output: ltfs on /mnt/ltfs type fuse (rw,nosuid,nodev,default_permissions,allow_other) Note thet this is of type "ltfs" but I am told that it should work like its a nfs. ltfs uses fuse under the covers.

In Redhat 4.x, we can use 'smbmount' to mount another linux samba server with 'user1'. But now we used redhat 5.3(64bit), there is no smbmount and I can only user mount command via root.
How can I mount a folder via 'user1', not root?

I also edit /etc/fstab and add the following in. hostname:/sharename /mnt/u1 noauto,user1 0 0

I have a samba share that I mount locally at boot through fstab. The share is writable and if I access the share directly, say with konqueror and smb (smb://hostname/sharename) then I can do anything I want (create, write, delete, edit, files/directories). I have a mount point on my local machine
Code:
/shares/mp3
and I (username dtest) was unable to do anything except read files and create directories trying to do them to the local mountpoint except as root. I figured it would be a matter of
Code:
chown -R dtest /shares/mp3
but I was unable to do that even as root, I kept getting permission denied. When I did
Code:
ls -alt /shares/ it told me the owner was 1000 and the group was root. Dtest was already a member of the root group and I was able to
Code:
chmod -R 774
as root but I still couldn't do anything except read and create directories directly via the mountpoint. Ultimately I solved this by changing the uid of user dtest via kuser and then just chowning my home directory back to dtest. It seems like as root I should be able to change the owner of the directory. I know it's because this is a samba share, but it doesn't make any sense why root couldn't just chown it. Is there another way to change the owner of a directory, or is this set by the machine hosting the samba share?
I bought SuSE 8.0 professional a long time ago, while living in Germany. I have an old German laptop that currently has Win2K installed, and I would now like to replace Windows with Linux on it. The computer boots the initial CD fine and gives me a number of installation choices. If I do not add a "root=/dev/hda1" to the parameters it stops the installation with a "Kernel panic: VFS: Unable to mount root fs on 08:01" and if that line is there the error message changes to 03:01.
Is this because the hard drive is already formatted to NTFS? Is there a way to delete the partition and create a new one from the Linux installation disks?
