Under debian i did this:
casey@t400:~/programs$ ls -l
-rw-rw-r-- 1 root root 2071 2010-03-28 05:15 urlgetter.cpp
Then
casey@t400:~/programs$ gedit urlgetter.cpp
and upon attempting to save the file, I get the error
"Could not save[...] You do not have the permissions necessary to save the file."
but I am a member of the group root:
casey@t400:~/programs$ cat /etc/group | grep root
root:x:0:casey
I own a particular file on a Linux system. I would like to give 2 groups (accounting, shipping) read access and only read access, and 3 users(Mike, Raj and Wally) write access and only write access. How can I accomplish this?
View 3 Replies View RelatedI want to simply mount an ext4 file-system onto a normal mount point in Ubuntu (/media/whereever), as read-writable for the current logged-in user, i.e. me.
I don't want to add anything into /etc/fstab, I just want to do it now, manually. I need super-user privileges to mount a device, but then only root can read-write that mount. I've tried various of the mount options, added it into fstab, but with no luck.
I am trying to change the write permissions on a file and On the screenshot you will see where i have underlined, its states i dont have owner rights to modify this file, how do I get owner Permissions when this is my installation..
View 9 Replies View RelatedI have apache2 running on my computer. I want to change the permissions for /var/www/ so that I can edit the files without a problem. Right now I can use the gksudo command, but I'd like to be able to have all the files available when using an IDE like eclipse.
I've read in several places that
Code:
chmod 755 /var/www
will do, but if I'm not mistaken that would give read/write access to anyone. I'm not in a production environment, so I'm not too worried about security, but I'd like to give anyone else as less permissions as possible. Would this be possible?
I recently Installed Matlab and it keeps giving me this permission error, even after running the following command.

Check file permissions.

I have created directories in root. I am looking for the chmod command to allow all users read and write permissions to a specific directory. I have done chmod 775 for a file but I need this for a directory. This includes permissions on all files and sub directories.

When I mount an external usb drive on linux (CentOs4), the permissions are by default set to read-only. Since there are multiple users on the computer who need to use the external drive, I want everybody to have rw permission for the entire drive. I also want them to be able to mount the drive if the computer has accidentially been shut down. They can use sudo mount to mount the drive, but this will only give them read permission, and I obviously don't want to allow sudo chmod.
Is there a default setting that I can change so that every new external usb disk automatically gets rw permissions?
What I want to be able to do, is have create a group, for example called "group1" and set its default permissions to read & write, instead of the usual just read.
So when I add a user into "group1" they automatically have read & write access to all files & directories which is in "group1".

I need to mount my ext2 partition with write permissions for an average user. Right now, I can only write to the volume using sudo or the root account.
/etc/fstab:
Code:
# Filesystem: Mountpoint: Type: Options: Dump: FSCK:
/dev/sda1 / ext4 defaults 1 1
/dev/sda5 swap swap defaults 0 0
[code]....
can't add the options uid=500,gid=500 to the ext2 volume because it says "bad option" I have 1 question. If you have a volume listed in /etc/fstab, and you try to mount it with different options than the ones listed in fstab, will it mount with the new options, or the fstab options?(e.x. if I try to mount /dev/sda6 with: mount-o auto,user,exec,rw,async. Will it mount with async or sync?)
I am setting up a file server using Ubuntu and want to make sure I set up a folder structure that will last. Where should I be placing everything that I am sharing (Music, Pictures, Videos, etc)? In theory, if I was setting this up on Windows, I would create a folder directly under C: and set up the different areas of sharing under that (not that that approach would be best either).
Based on constructive criticism, the question is rather ambiguous. My question could be restated to ask "Where shouldn't I set this up? Would /usr be an appropriate place to start? Or would /opt be better?
There is a folder that is owned by user tomcat6: drwxr-xr-x 2 tomcat6 tomcat6 69632 2011-05-06 03:43 document. I want to allow another user (ruser) write permissions on document folder. The two users (tomcat6 and ruser) does not belong to same group. I have tried using setfacl: sudo setfacl -m u:ruser:rwx document
but this gives me setfacl: document: Operation not supported error.
Write a short script that tells you whether the permissions for two files, whose names are given as arguments to the script, are identical. If the permissions for the two files are identical, output the common permission field. Otherwise, output each filename followed by its permission field
View 5 Replies View RelatedRelatively new to Linux, but I'm trying to grasp the proper way to modify the sudoers file. As an example, what would I have to modify in /etc/sudoers to allow a user (say 'user1' for the example) to be able to add/remove software through yum? I'm aware of the fact that I need to use visudo and how to use the vi editor. I've Googled this topic and while I've found a number of pages on the topic, I never see many examples.

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.
When I ls -l /etc/passwd, -rw-r--r-- 1 root root /etc/passwd When I login as myself, and rm /etc/passwd, it asks: rm: remove write-protected file '/etc/passwd'? If I say yes, will it actually delete the passwd file?

View 9 Replies View RelatedThere are lots of tutorials and opinions on file permissions and web hosting.
So lets say I wanted to allow write permissions to the /var/www folder.
which would be best practice?
Chown -R user... allow a specific user to have write capabailities.
use gksudo nautilus (unsure what this does)
or open the folder to all parties.
If anyone has any opinions on file permissions in general or web hosting security then feel free to throw them at me.
