Ubuntu :: Change Default File Permissions?

Jul 3, 2011

my dad has been using Ubuntu for a few weeks now and likes it, however he's having some issues regarding read-only files. He's a doctor and frequently has to download word files to edit, however they always download as a read-only file. While this isn't particularly difficult to do, he finds doing it tiresome and because he isn't the most proficient PC user, may have difficulty with it when I return to school after the summer. I was hoping that there's some way to change the default settings so that all files downloaded are writeable.

Additionally, he has a number CD-RWs which he both retrieves files from and stores them to, however when trying to access these CDs he is told that they are read-only. Right clicking on the CD and trying to change the access permissions doesn't work (says that permissions can't be changed because the disc is read-only).

OpenSUSE :: Change Default Permissions For New File Created With Dolphin?

Jun 28, 2011

When I create a new file/folder in a ext4 data partition, it has permissions:

owner: rwx
group: r
other: r

I would like to change this default to:

owner: rwx
group: rw
other: -

I tried changing fstab, but umask and guid are not supported mount options for ext4. What can I do?

Note: I know I can do a chmod, but I don't want to do this again and again for every new file I create.

Ubuntu :: Change Default Permissions Of Removable Media Mounted Via Nautilus?

May 2, 2010

behavior in 9.04:plugged in a disk, mounted it and it as readable to the world.this is intended because it is shared via samba.behavior in 10.04:the disks have 700, meaning, they are not readable by samba.this is a problem.this is the best solution I've found so far:http://www.mail-archive.com/ubuntu-u.../msg10951.htmlexcept, that the mentioned means to fix this are gone.(gconf-editor -> ..., storage and preferences -> removable media)after 3 hours of googleing and reading I'm rather upset about this bug.so please, if you are thinking of suggesting fixed entries in the fstab or anything else that will not work with every media that is plugged into this box, just close this tab.

Debian :: Change Default Permissions For Newly Created Files?

Jan 19, 2011

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).

Ubuntu :: Change File Permissions To Change Background Screen?

Feb 21, 2010

I'm new to Ubuntu Linux but have many years on windows platform. Please can someone help me with how to change the following items.

No.1 I would like to change the HORRIBLE!! YAK!! brown background color behind the word Ubuntu in the start up screen when the machine loads up (before the login). I have located the image file for this which I have found to be: /usr/share/images/xsplash/bg_2560x1600. jpg but the OS says that root is the owner and that I don't have permission to change this. So how can I change this for a color I do like.

No.2 I would also like to change the login dialogue screen style. I know this is possible but again I'm fumbling to see how I can do this. I have tried with the start up manager but every attempt fails, the settings don't take. Once again I suspect permissions are at the bottom of the problem?

No.3 Would like to have a colorful splash screen image on boot up, I've managed to remove the old one (small white 3 ring ubuntu logo on black background) but havent been able to install or replace with a new one. Its been incredibly frustrating, I'm feel sure I'm missing something simple here. Wondering if its permissions yet again?

Anyone who can offer help on any of the above, guidance or advise me would be much appreciated. Please bear in mind that I'm still very much feeling my way with Linux so keep it simple.

Ubuntu :: Setting Default File Permissions

Jun 26, 2011

I have a file server running a cronjob to reset file permissions on a regular basis. I was thinking, I wonder if there is a way to do the chmod and chown command in a single command, as I always have to do both on the same folder, the way that you can do "chown root:users Uploads" instead of having to do two separate commands for chown and chgrp.

Then I got to thinking, are these commands even necessary? Every file copied or moved into these folders by any user needs to be something like "chmod 750" and "chgrp root:users", so rather than running a cronjob to do these modifications at regular intervals, there ought to be a way to set the folder permissions so that any files contained within will have these permissions.

The problem arises because users create documents, then a supervisor with elevated privileges can move those documents into a shared folder, however the permissions are wrong, they are user1:user1 for the owner and group and the other users can't read the file until a cronjob changes the group to be users. This has actually been acceptable, but certainly there is a better way to do this.

Ubuntu Servers :: Default File Permissions Apache /var/www/?

Jan 14, 2010

This is probably a pretty basic question seeing as I'm pretty new to Ubuntu Server. I'm running a simple website from my Ubuntu Server machine with The files are all stored in /var/www/ and then subdirectories. The problem is that when I add files through FTP I need to go and change all of the file permissions since by default they do not have read access so can't be accessed through a web browser on another machine.How can I make the default permissions readable for the directory and all new files that will be moved in it

Ubuntu Servers :: Default File Permissions For System Folders

May 5, 2010

I had a major raid event recently which caused my Ubuntu 9.04 server to recover part of its file journal on the system partition. This caused some of the file permissions to go all funny and I now need to change them manually.

What the file permissions should for the following folders:
/etc/
/home/
/lost+found/
/mnt/
/root/
/sbin/
/srv/
/tmp/

The server is running and I fixed the some of the ownership issues already. I use a basic LAMP setup with samba, and proftp.

Ubuntu :: Set Default File Permissions For Newly Created Directories?

Nov 18, 2010

I'm just wondering: I know that umask sets the default file permissions for files, however I want to know if there is anyway to set default file permissions for newly created directories.

For example, I want my user to create new directories that anyone can access and modify (777) but I want the new files the user creates to be 755 (read by everyone, written only by user).

Is this possible?

Fedora Security :: Default File Permissions In /boot?

Does anyone know why files in /boot are world-readable (particularly the initial ram disk)? I'm not an expert, but I would not expect anyone except root or a sudoer to have the ability to read these files.

General :: Cannot Change File Permissions On A Mounted File System

Apr 6, 2010

I have an ntfs partition that I wish to access as a normal user(non-root). For this I did the following. As root I created a folder /windows and did a chmod 777 -R on /windows. Then I added the following line to /etc/fstab

Code:

/dev/sda3 /windows ntfs-3g defaults,nosuid,nodev,umask=000 1 0

Now, the partition is mounted alright but the problem is that when any other user (non-root) creates a files in /windows (say by executing touch newfile) the newly created file has the owner and group set as root. The non-root user can create the file and he can also delete the file, however, he cannot change the permissions of the file and also the owner:group is always set as root:root. How do I get across this problem, i.e. how do I mount a partition, so that a non-root user can also change the permissions and ownerships of the files he creates.

General :: Concept Of Umask - Default File And Directory Permissions

Apr 14, 2010

I am using Red Hat Linux 4 .There are some few questions in my mind related to umask. I want to know that is the default file and directory permissions ?

- When we use umask (022) command in terminal. and create a new file then the permissions applied for new file is for that session and when the system will reboot linux will take automatically its default permission from etc/bashrc or /etc/profile ?
- Can we make our own umask or the professional way is to follow 022 only ?
- What is the benefit of umask in Linux?

CentOS 5 :: Restore Default File Permissions - Server Nonfunctional

Dec 4, 2009

I was working on a shell script to change the permissions of large directories and subdirectories because of an exploit discovered in the programs that run in those said directories that allow a client to upload and download files to the server. Loan behold I accidentally added a space and had something along the lines of "chmod -R 770 ." run on / logged in as root.

Yes, it was an incredibly noob move on my part, but nothing ventured nothing gained. I am surprisingly calm about this. I tried sliding in my CentOS installation disk and "Upgrading" CentOS but that only made it worse, beforehand I made everything owned by root so I could at least log into GNOME. This does not work for obvious reasons, namely having to change the permissions back for every user and every group, which far beyond a possibility.

Ubuntu :: Change The Permissions Of A File Within The Script

I'm trying to install a script and I need to change the permissions of a file within the script, but I am being denied from doing so. I know that I could change the password of ROOT, but I don't really feel like going through that again when I can just use 'gksudo nautilus' in Terminal. How can I change the permission without being on Root?

Ubuntu :: Unable To Change File Permissions

Dec 4, 2010

I recently did a fresh install of Ubuntu Maverick, and have found a slight issue with file permissions. Before starting the installation I backed up all my files to an ext3 partition, then during the process I moved all of these files over to an NTFS partition that I am using as a joint storage location for both Ubuntu 10.10 and Windows 7. Upon booting into my fresh Maverick install I found that all the files on my NTFS partition are now owned by root and I am unable to change the permissions using the conventional methods I am used to. I have tried using the GUI method through the properties of the folder, I've also tried using chown and chmod, but all to no avail... No matter how I make the change to the permissions, it will always revert back to root within seconds. who desperately wants full read/write access back to their data?

Ubuntu :: Mass Change File Permissions?

Dec 26, 2010

I recently backed up my home folder onto another HD. When I tried to transfer the files from the other HD back to the original HD after a fresh ubuntu install I noticed all my files were restricted to root access. Even after moving the files back via root access I can still only access them that way. Is there a way to mass change the permissions to all the files and folders within my original home folder?

Ubuntu :: Can't Change File Permissions Even As Admin

Sep 1, 2011

I've been having a very strange problem, and not sure for how long... but basically, my system wont allow me to change file permissions, even in root mode! I run Ubuntu 10.10 with Gnome and LXDE, kernel 2.6.35-30-generic. It's particularly problematic if I want to run some binaries or programs that you need a shell script to start up (i.e. any new version of Firefox). The usual right-click then going into permissions doesn't work, it just resets whatever changes I make. The weirdest thing is that using the chmod command as root also has no results! The files keep the exact permissions they had before...

Ubuntu :: Cannot Change Folder / File Permissions On Entire HDD

Apr 17, 2010

I have two drives in my computer: a 160GB and an 80GB. The 80 holds Ubuntu, the home folder, etc. The 160 is for other files. I need to change the read-write permissions on the 160, but I can't. If I do it through the GUI (right-click>permissions) it just changes back instantly. If I do it through the command line (even with sudo), it has no effect.

Ubuntu Servers :: Cannot Change File Permissions On Server

Aug 25, 2010

I'm working on a remote Ubuntu 9.10 server, which is accessed via VPN. I installed Joomla, but had difficulty uploading new components, which I traced to a file permissions problem. I used FileZilla to FTP onto the site and tried to make the chmod changes I needed, but the commands kept failing. Eventually, I contacted the sys admin and told him I thought that there was an ownership problem with the directories. He checked and told me that I was logging in with exactly the same user name and password that he was using (it's not a live system currently) and that he could make chmod changes without any problems. Because all my attempts were still failing, he eventually did the following:

chown -R administrator:administrator /var/www

/var/www is where all the Joomla files are stored and Administrator is the user name.Now I find that when I run a chmod command in FileZilla, the server reports that it worked (see below):

Status:Connected
Status:Retrieving directory listing...
Command:CWD /etc

[code].....

However, if I go back and check the tmp folder permissions, I find that they are still set to 777.This still looks like an ownership problem to me, but I don't understand why the server seems to think that the chmod changes are working, when they aren't.

Ubuntu :: File Permissions / Ownership - Even Root Cannot Change

Aug 30, 2010

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?

Ubuntu :: Change Permissions On A File In /proc/sys/fs/inotify?

Trying to change permissions on a file in /proc/sys/fs/inotify. The command syntax are:

Code:
sudo chmod u+w max_user_watches
and the result is:

Code:
chmod: changing permissions of `max_user_watches': Operation not permitted Also tried to change it when logged in as root, same results. Parent directory permissions are dr-xr-xr-x, and are the same up the chain. Tried to change the directory permissions to u+w, that didn't work either. FWIW, /proc is part of the / partition, and it has ~600MB free space.
