If I am not the file' owner or root, can I use chmod to change the file permission?
Assume I have group/write access to the file, e.g. 775
that works to disallow non-owners from renaming the file, but what I wouldlike to do is disallow EVERYONE ( including the owner of the file ) fromediting, moving, or changing the filename once it is created. the only personwho should be able to make those changes is a special user.

View 8 Replies View RelatedI recently installed Ubuntu 10.4 on an Intel machine. The machine also has Windows 7. So some of the partitions of the hard drive are Windows compatible (NTFS). They are all mounted when system is booted with Ubuntu and all files are accessible. However, when I try to change permission or limit access to a group, CHMOD command does not work. It doesn't return any error and everything seems to work fine but I can't change any permission.
View 8 Replies View RelatedI have setup my debian 8 web server.
For some reason I am having some issues with permissions of some images. They don't render because they are not set to 644. Now for some reason when I uploaded these files onto my shared hosting with cPanel the files work fine and permissions are fine. I can see there is a permission issue for the files locally on my Mac (OS X - El Capitan).
When I changes these locally on Mac the permissions go all weird and are prefixed with Custom, rather than mac-user-name: Read & Write, staff: Read, everyone: no access. then changes to custom: read & write etc. So then i tried changing permissions on web server see below and I get permission denied and after all the files are gone, i can't delete the images folder through SFTP or SSH. I changed back the image to 755 and tried deleting and still nothing. Not sure what the problem is. Before I chmod I checked that the images are set to the correct user and group as per the rest of the site.
So I try:
Code: Select alluser_name@debian:/var/www/html/_files$ chmod -R 644 images
and I get this return:
Code: Select allchmod: cannot access ‘images/box-icon.svg’: Permission denied
chmod: cannot access ‘images/ie-icon.svg’: Permission denied
chmod: cannot access ‘images/google-plus-icon.svg’: Permission denied
chmod: cannot access ‘images/mobile-ready-icon.svg’: Permission denied

How can I give execute permission to chmod command from run level 3.Because in GUI mode we have the execute option in the properties of file. E.g. I gave following command
chmod -x chomod
After that I want to give the execute permission (x) to chmod command again but how from command prompt?
nfs mounted directory which is mounted rw. I and everyone else are members of a common group. We all have write permissions in the tree: All files and directories in the tree are in the common group. All directories are set to 775 and all files are set to 664 or 775, as appropriate.If a file is owned by someone else, even though the file and the directory are group writable, I get permission denied when I try to chmod the file.

i installed Slackware 13.1 64 bits in a asus laptop and until now everything is running ok. But when i tried to mount a usb pendrive, i just can mount it as root;well, i thought there would be no problem, i will change permissions with chmod and everyone could access, read and write on it the command :
mount -t ntfs /dev/sdb1 /mnt/kingston
and making ls -l the result is :
drwx------ 1 root root 12288 Dec 8 17:20 kingston
so next i wrote (as root):
chmod 777 -R kingston
and the message was "Operation not supported" i tried also changing the ownership permission :
chown molei:users /kingston
drwxrwxrwx 1 molei users 12288 Dec 8 17:20 kingston
so, apparently i would have total access to the kingston directory; the problem is when i try to copy something to the kingston dir, an error msg. appears :
cp: cannot create regular file `/mnt/kingston/linux_guide.pdf': Permission denied
I am desperately trying to recover two folders from a Freecom FSG 3 NAS. As far as I am aware it is running Linux 2.6 based on Snapgear. After working through the hardwares' recovery procedure a number of times, the state of the device appears to get worse and worse. So I have attempted to rescue the files by using a program called Putty to access the device over SSH.When I access the device using Putty I login as admin. The folders I need to recover are located in the home folder. Listing the contents of the directory I get...
/home $ ls -la
ls: ./.twonkymedia: Permission denied

Is possible to make a folder permission like below?
-User can create files/folders in the shared folder.
-But the files/folders they created, cannot be delete/change by em.
(only can be delete by root users)
-Each new files/folders created will auto owner to root only.
I'm using ubuntu 11.04, I'm having some problem of ownership while sharing folder/files. to share i change the folder share option:1. Share this folder, then followed by 2.allow others to create and delete files in this folder3. guest access.Now if someone in my local network edit any file and save it, it gets locked. if some one copy their file in this folder the permission is marked as "no group" "no owner". and they get unaccessible to me. i tried doing chown <user> <folder> but it says Operation not permitted. Now how i can possibly share my folder on local network so that they can be edited by others without getting locked down , if they copy files i can able to modify them.

I wanted to create an user but don't allow it to see the other user's home folder so I made chmod 0750 /home/folder and it worked fine so I went ahead and decided to completely forbid access to the root folder and I had the "great" idea to make chmod 0750 /, and now I'm having problems with wine and other applications, in example I used to have a folder in this address 209.239.114.51/mmgr but now it's giving me errors and if I try to run some applications I got error "There was an error creating the child process for this terminal"

View 6 Replies View RelatedI want to have two kind of users in a work machine having ubuntu 10.04,
1) He is the admin, have sudo privilages and install, do all types of work, his username is abhilash
2) A user who is normally a IT administrator, who can just install or remove softwares, but cannot access files of abhilash.
I'm trying to do this and my head is going blank, The problem where i'm stuck is, if IT admin can install softwares, then he can become sudo as sudo su, then he can view my files
So here is a small test i did, first with abhilash.
Code:
Now others and group don't have any permissions! But when IT Administrator becomes root, he can see this file

View 4 Replies View RelatedI've got some trouble while trying to install some applications on my linux system. It is said that the files in my /var/www/html/xxx directory, where I put them, is not writeable. The command chmod 777 xxx has been tried to make it work, but the error remains when I opened the applications again.
To be specific, I want to install phpFreeChat on my system, so I put those files in the /var/www/html/freechat directory, cd there and typed chmod 777 data/private, chmod 777 data/public on bash. Here's the result of list -al data:
drwxr-xr-x. 4 root root 4096 Jun 17 15:07 .

phpFreeChat cannot be initialized,
please correct these errors:

View 6 Replies View RelatedI was trying to install vmware.bundle file, and found a terminal command that helped me install the program.
su
chmod +x VM*.bundle
./VM*.bundle
I was just curious what the command chmod was for? Just trying to understand the terminal a little better.
I've hit a wall here; I'm attempting to find some way by which to view files and cd into directories on a device mounted read-only. So I need the permissions to read, write, execute (and the same with directories), but chmodding is out of the question because I don't want to alter the drive one iota.
I guess what I could do--what I was thinking of initially--was to dupe the whole drive and then mess with permissions. This wouldn't affect the original (actually I'm working on a duplicate of the original, but I'm treating it as if it were the original) but I was hoping for something that would maintain data integrity. This is a forensic application and not altering the data is very important.
