the terminal and logged in as root i was changing file permissions and happened to change the root folder to 700. Now my icons have gone and i can't even access the terminal.
I was just wondering if it is possible to go to rescue mode using the cd and restore all the appropriate file permissions to root/ users if possible
want 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.

View 3 Replies View RelatedI used to use the root account for everything for more than a year then I moved to a user account for security reasons but almost all files had root as owner so I could not go 5 minutes without having to change to root and then change the owner of a file to my username to make it usable. I got fed up with this so I just changed the owner of every file on the system to my username instead of root.
command chown -R myusername * in the base directory /
Everything was fine until I restarted and the login screen became non functional and I got 2 error messages related to xsession and gnome errors. I think this is because the login screen might have its own user account and it cant access the files for the login process because it is owned by myusername. So my question is what is the user-name of the login account and what folders/files need to have their owner changed so the login process can work? I'm on 10.04 lucid.
I am attempting to make a backup copy of a file, but every time I try to copy the file, I get a "permission denied error -- even when running as root. The file is on a volume mounted as /media/Data . No problems reading/writing other files on the volume.
Here is the info on the file:
-rw-------. 1 root MailServer.img
I've tried chown but get the permission denied as well. This is a virtual machine image that runs fine, but even with the VM completely shut down, I get the same error.

View 1 Replies View RelatedI 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'm running 2.6.35.14-95.fc14.i686 on Gnome 2.32.0. I've been trying to assign a keyboard shortcut to Suspend the system when activated, but it doesn't work because to suspend the system you need to be root. The command I've been using for the shortcut is terminal "pm-suspend".I don't wanna set up the working user as root. Is there any way to get around the root authentication while suspend to make the shortcut work?
View 4 Replies View RelatedI have a system in which I do not have root access to. On that system, I have my own directory which I share with other users. I am trying to clean it up when I noticed that there was a subdirectory created by another users in my group that I cannot delete. It has all the permissions set besides global write. How can I delete this folder without root permission? I can't even chmod or chown it.

Protect against root password change[Log in to get rid of this advertisement]I have recently had to force a change of the root password on a linux box I was running. It was a test system which I had not used in a while, so I forgot the root password (not so smart).Anyway, I found that it was amazingly easy to reset the root password. Here is a straight forward article on how to do it.URL...
My question is: how can you protect against this? I see this as a security hole.I understand that the user must have physical access to the computer, but if I want to lock the system down so you cannot easily enter single user mode or the root password cannot be changed.
what can I do if I changed my ubuntu password and cant remember what it is?I only have 1 user on my system - me, and I changed the password today, thinking it was obvious to remember my new password, but I cant remember it exactly

View 6 Replies View RelatedI've started to get emails that would typically come from [URL] as [URL]. These emails come from services that send out emails (backup programs) directly, or from cronjobs. I've logged in as the non-root account and either sudo su - or su - to root and the restart the service at one point or another. If I login directly as root and bounce the service or cron the emails come across as from root. I don't see anything in my environment variables after I su to indicate what would cause this. I'm not sure where else to look? A pam setting? This seems to have happened between Fedora 10 and 14 (did a bunch of overdue upgrades recently) I've only got Fedora so I don't have anything to compare to. In Fedora 10 I did not have this problem.

I don't think this can be considered solely an "upstream" problem, because I first tried it in Arch using the same version of glibc, and the final command causes both gnome-terminal and xterm windows to disappear.
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.
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?

How is it possible that I get perm denied when I'm copying files in console.
