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".

How can I accomplish this ?
I'm having an odd problem (although I'm probably missing something obvious to a non-semi-newbie):I have a directory used for samba shares which is owned by user fred, a system user which the windows clients on my network authenticate with to access the shares. I, roger, want to access the directories without having to put my 'sudo boots' on every time, so I made the directory group users and added roger to that group, and changed the file/folder modes from 0755 to 0775.However I still do not have write permissions inside the directory; I still seem to be considered 'other' and hence only have read and execute.

Each user should be able to create files and modify each others'files, but should not be able to delete any one elses files in a directory.chmod -1777?setfacl?
View 2 Replies View RelatedI have a group (GROUP) with a number of users. I recently added a new user (NEW). NEW is able to read but not write group files, whereas all the other users in the group can read and write to the group files. The permissions for the group files indicate that all members of group should have write permission -rwxrwxr-x
/etc/group indicates that NEW is a member of GROUP
...
GROUP:x:501:GROUP,OLD,OLD2,OLD3,OLD4,....,NEW

Don't know if it matters, but both OLD and NEW write to the GROUP files over an internet connection. why NEW can't write to GROUP files? Is there a maximum number of members in a group that I might have exceeded?
On an Apache2 server someone else setup, I have a folder with drwx--x--x permission and the php file can still write in the folder. But on my own setup, I need to set the same folder to drwx--x-wx. Inside the folder, I have a index.php that runs just by setting rwx--x--x but on my own setup, I need to allow read permission for others/group before it can run: rwxr-xr-x (or else I get a blank page). I tried changing the folder and files to root but it's the same.
View 5 Replies View RelatedOn one of my machines the DVD/DVDRW/CDROM drive appears as /dev/hdc and is not identified as an optical drive by HAL. It is owned by root: disk and thus no users get permission to read/write in the device (not even those in the cdrom group). This stops playing DVDs, ripping CDs, no notifications appear when a disk is inserted, etc. etc. When I set the permissions for all to read/write from the device then users can access but still no notifications are shown.
On all my other machines the optical drive is identified as /dev/sr0 and is owned by root:cdrom . All have Slack 13.1 . Previously with Slack 12.2 this machine still had the drive in /dev/hdc but the permissions were right (I think because I added it to /etc/fstab with options for users to access it). I believe the problem is down to HAL not setting this drive to the correct group, but how do I fix it? I hate HAL, it has a mind of its own, just like in the scifi movie

I have a requirement to have a read-only access to a folder and sub-folders and the group that currently holds can't be used. Because it has write privileges.

I'm running Ubuntu 11.04 (guest) on Windows 7 (host) with the guest additions installed. I have an auto-mount folder that maps to my D: drive on the host which I can access using sudo ls /media/sf_D_DRIVE - however, even when my user (ross) is a member of the vboxsf group I get a permission denied error when attempting to explore it. I have restarted since adding my user to the vboxsf group.
This should work because I am a member of the group (which has rwx rights), so why doesn't it?
ross@panther:~$ ls -l /media

Though, I also get this error for any other directory I try in. When trying with 'sudo' I am told that it is a "bad idea." I have never used makepkg before, so whatever is wrong might be obvious; I have never "fine-tined" my makepkg.conf before, either. Probably not relevant, but just in case: easy-e17 is a group of files from the Arch User Repository for installing Enlightenment (DR17). Perhaps there is something I need to install in order to make packages from the AUR? Or does that sound ridiculous? I wouldn't know.

I 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 would like to know how can I share a folder in samba with no need of user and password with write permission, with no need of using guest user.
View 3 Replies View RelatedI have mounted a iomega file system on a cetos os machine using

(** mounted as root) The mounting works fine.
The problem arises when I try to create a sub-directory inside the mounted directory. All the newly created sub directories become write protected.
I am accessing this file system from R software and it needs to write/create directories in side this mounted directory.
how can newly created sub-directories will become automatically writable, so that R can create new sub-directories and write data inside those directories.
