Ubuntu :: Ownership & Permissions Change When Files Burned To DVD+RW?
Jan 18, 2010
After burning files to DVD+RW, the owner is changed to root, and all permissions are read only. I want to periodically open these files, update them, and save to the DVD again, but I no longer have permission and cannot change the permissions since I am no longer the owner. I tried sudo commands, but get responses "Read only file system". I have erased and reformatted the DVD and started over but get the same results.
I have Ubuntu 9.04, and have tried Brasero and Nautilus and get the same problem. Am I using the wrong kind of DVD/CD?

I have been VERY lucky and managed to restore from a formatted ext3 /home/ partition. I used testdisk to reset the original partition which had had nothing done to it since formatting(!). However some of the file permissions are a altered and I cannot change them. I have tried "su chmod" and even temporarily enabled the root account itself and tried to alter the ownership/permissions from root 'proper' without it helping.
Here is an example of the output of ls -l
drwxr-xr-x 2 martyn martyn 4096 (date) (time) sponsors
?-----S--T 63231 92820383 44090688 4286824785 (date) (time) order.xls
The first line looks like a normally formed output and indeed is readable. The second line looks corrupted and I don't have a clue how I can reclaim this - or even if it is possible. Should I count my blessings most of my files are intact and leave those be?

I finally replaced my Windows with Linux.. However, I need to run applications and modify files that are on NTFS mounts. I am unable to change ownership, permissions, and groups on these files so I may modify them without having to copy. I have several times attempted to chmod, chgrp, chown, etc.. while logged-in as root user; however it is to no avail. The owner and permissions are still geared towards root. can I change ownership and permissions on NTFS files so I can modify them without having to convert/copy them over to ext4 or different file system?- Matbtw: I am using OpenSuse 11.4 and running Windows apps with VirtualBox (with Vista installation image). I still have Win7 on my computer (non-emulated) and I would like to keep some files on those NTFS partitions so when I occasionally need to boot into Win7 I can modify those files because Windows blows and doesn't support Linux.

Being new to Linux, i've just about got used to the Debian setup procedure now, but had a quick question on the default ownership of files and folders. On my default Debian installation, almost all the folders and files are owned by root:root. Is this the correct advised configuration or should the folders and files be owned by a user without root permissions - eg user:user?

I have a vary unique problem with file and directory ownership. I need to change the ownership of multiple files and directories under a specific subdirectory.Under this directory structure there are files and directories owned my different users and groups. I need to change all files and directories owned by "user1" to "user2". but if any are owned by "user3" I need those left alone.Is there a simple way to do this or will I need to traverse the structure and change things one at a time.

I installed Ubuntu from the alternate cd a few days ago to save space and resources on a very old laptop. (install command line, then add what I wanted) But I have struck an interesting problem with file permissions. Various programs like synaptic, leafpad, pcman, Banshee, all require I enter the root password to execute them (or sudo command from terminal). I want to change synaptic from root ownership to sudo and leafpad etc to execute without using the sudo command in terminal. I could get comments on the commands before I execute them in terminal and if I am introducing a security problem, as I am still learning bash. $ sudo chown sudo:sudo synaptic
I would still be asked for my sudo password before being able to open synaptic? As in standard Ubuntu instead of root password.$ sudo chmod 777 leafpad pcman Banshee All users could open these programs from the menu? I have my admin account and a general account which I use for everyday things like surfing the net and listening to music.

I've been using Ubuntu for a few years and I am having issues trying to load .jar files and .exe files in Wine. I keep getting an error message that says my computer doesn't have permission to load these files. I've done some research and found people saying to enable the file as executable in the files properties, to enable executable in the permissions folder, and to allow source code on the Ubuntu Software screen, but whenever I try to check these boxes, they immediately revert to having a line through them instead. I remember when I was running Ubuntu a few years ago I was able to completely disable this restriction in terminal, but I can't remember what I did.

just trying to learn linux here and have some comfusing moments.it is my understanding that if you own directories and files you maychange the group, ownership, and permissions on all of these as you desire.however, in my case I cannot make any changes in my setup on group, ownershipor permissions on any of my files or directories.get error message <operation not permitted>. I know as root you ar supposed tobe able to do anything you desire, however in my case I can go in as root andtry the same commands with the same results. it is as if I am locked out ofsystem as far as any changes are concerned.on my jump drive I have:
total 83832
drwxr-xr-x 26 jevans root 16384 1969-12-31 19:00 .
drwxrwxr-x 9 jevans jevans 4096 2010-01-15 12:51 ..

I use Linux but have a computer with windows I use for gaming. It died and put the hard drive into another computer and used knoppix to recover my files. I looked at the ownership of the windows files and the owner is knoppix. Now I am concerned that ownership will not work on my new Windows computer (when I finish building it, that is). Since I don't get into Windows much I have no idea what those permissions should be.
If I copy them with owner knoppix can I even access them in Windows to change the ownership to whatever Windows will accept? If I change the ownership before putting them on a CD with knoppix, can I write the CD? I will have to use the hard drive on the new windows box so will not have access to the files later (unless I also copy them to my Linux computer for safekeeping). At least I know the ownership changes to make with Linux.

I am writing a script that is checking the ownership and permissions of a directory. If the directory in question does not have the correct ownership and permissions, the script will run the appropriate commands to give it the correct settings. The if...then...else syntax. The idea here is the following:
Code:
If <directory> no eq = <ownership root:root> && <permissions 755>
then chown root:root <directory> && chmod 755 <directory>
else exit
fi
What would the correct syntax be for the If line of the loop in question?

I run the servers hosting an intranet, a couple of services and an external websites for my club at university. I'd like to back up all the config files to some version control system to keep track of changes, in case one of my colleagues breaks something. The idea is to keep snapshots and then just roll back the required file in case something happens.
Now to the main issue: How does a version control system handle file permissions and ownership? Does it keep them? Does it set the permissions of the user who committed the last change? These are important questions as we have multiple daemons with different users...

I've just read that I can't change the file permissions of files and folders if they are sitting in what was my old Windows D: drive. Is this correct? If so what is the work-around?
I don't want to have to cut and paste that entire D: drive's contents over to a recognised Ubuntu folder. I had in my mind that this D drive would continue to be my data dumping ground, to which I need read/write access to.

My laptop has Ubuntu as a dual boot. Many times I want to copy files from one folder to another. But I run into permissions problems.
For example, I downloaded a program that required me to put a rules file in /etc/udev/rules.d But when I tried to do that, I got an error: "permission denied"
Is there any way to change permissions on folders so that I can freely copy them from one folder to another? That would make life a lot easier.

I just installed Karmic, but I can't copy an old user's home folder (/home/oldusername/) because everything is owned by root.I read but I'm concerned about messing up the system or the files in that old user's folder.So, how do I adjust the permissions of the files in /home/oldusername so that I can use openssh to copy them over my home network to my other computer? I have the ssh part figured out, but the files will not copy to the laptop due to permissions.

I have a NFS shared directory between two linux machines, one with RedHat3 and one with CentOS 5.4.On the CentOS 5.4 machine I have InfoBright installed. In that directory, I want to create files with InfoBright and then to select from them with MySQL on the RedHat3 machine.The problem is that InfoBright creates files with 660 permissions and mysql with 666, and I cannot SELECT from any file due to the fact that is not "readable by all"(this is the actual error). I can change the permissions manually, but I need them to be created with 666 permissions, so that I can import them automatically on the other side with a script.Is there any way to change the permissions of the InfoBright created files?

I'm new to Debian. I've read the documentation on this but it is too heavy for a new user to understand. I would like to change the default permissions for newly created files/directories.
I want all newly created files by 'user1' to have the default permissions of:
1. "owner can read and write"
2. "group can read and write"
3. "other can read only"
Permission 1 and 3 are already default. But I would like number 2 to be default as well. (the current default for group is read only).

I have a Qnap 219p NAS to which I have connected a USB external harddrive. I can access the external harddrive from my windows box using the network share, but at first i couldn't access the folders. The permissions set in the NAS GUI for the external drive is correct and are identical to the permissions set to the 2 internal drives.
I ssh'ed to the nas and used 'chmod -R 770 /share/external/sds1' - this granted me access to the folders, and some files. I can open all files in the root, but if I go just 2 folders 'deeper', i can't open the files in this folder, and in the folders after that.
In ssh, if i navigate to the folder wher I cannot open the files and use 'ls -l', i can see that the permissions (770) hasn't been applied to these files. How can I get chmod to apply the 770 permission to all files, folders, subfolders and files in subfolders etc., without having to chmod every folder one by one?

I work with this travel company that host sites for different agents. They have ALL the sites in one directory and each site has its own search.php file. How can I locate, and change all the search.php files permissions to 644 in one shot? Is this possible maybe with the find command? I read the man page for this but I am not sure how to write out the command.
