Ubuntu :: SAMBA Default File Create Permissions?
Mar 28, 2011
Files saved on our ubuntu server via samba server are all being created/saved as read only (-rwxr--r--). The users are MAC Users who are connecting via finder.I have taken 2 steps:First I added the lines "umask 0000" to the .bashrc files in the users' home directories.Second, I have modified the /etc/samba/smb.conf file such that I set "create mask = 0000" and also "directory mask = 0000" but the files are still being created as "-rwxr--r--".

I've got a small issue that when a Windows user creates a new folder through Windows Explorer (from the menu or by right clicking) the new folder is only accessible to that particular user. Example: user SABKAR (member of the HR group) creates a new folder called MarcTestMenu in a shared Samba directory through Windows Explorer:
[Code]....
At this point user MORAMY cannot copy a file or open the directory MarcTestMenu. MORAMY gets a 'not accessible' error message in Windows. If I su to the Samba box and issue this command:
[Code]...
how I can get the correct default permissions when users create directories through Windows?

I have mounted samba volume and I need to have write permissions for every new folder that's being created (currently, by default, on every newly created folder i have only read and execute permissions).I tried changing umask, but with no effect on mounted folder, umask changed only for local filesystem. I tried mounting with umask option, but with no effect again.I'm using ArchLinux on this machine, and I installed samba using default package manager (pacman).

I have a fileserver running openSUSE 11.2 and samba services for file access from MS Windows based workstations. My question relates to changing default permissions on files and directories created from the windows clients.
Following are extracts of the /etc/samba/smb.conf file :
Even with the above entries, sometimes there are files and directories created by the windows clients having permission
Probably my lack of understanding in ACLS.

I have a problem with file permissions over samba. I am running a web server, and this web server needs to be able to delete a file. The php code is correct, because it works on other sites. The php code is failing when it deletes a file because it is being ran as the www-data user. And the permissions on the files that are created on the share are as follows:
ns$ ls -l
-rwxr-xr-x 1 root root 129628 Feb 6 08:16 20110206071748532.pdf
This directory is mounted on:
/var/www/files/23982dbb7a454425ce17a22bedc00776/scanned/AEC_Scans
This is done with the /etc/fstab file:
//192.168.58.2/Scans /var/www/files/23982dbb7a454425ce17a22bedc00776/scanned smbfs username=administrator,password=somepass
[Code]...

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.

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).

I want to back up an entire Linux system on a 3Tb external Western DIgital USB3 drive.
I do not want to reformat it from what it is, apparemtly NTFS.
Is there a utility that can act like a file manager like mc, that will permit me to create an ever expanding (to 320Gb) TAR file that will retain all the original file permissions. I have had nothing but disappointment with Linux backup utils with a FAT32 external drive, and I am concerned if I just try an tar the entire drive at once, with around 3 million files, I might run out of memory.

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

I have set up a computer to use as a file server using Samba. I attached a 1TB hard disk to it and had the system to mount it automatically. I have 4 user accounts which will be able to access this network share. An administrator account is called "server". I'll call them user1, user2 user4. This is the folder structure:
+-/mnt/FILES
+-BACKUP
backup files (accessible only to "server" user)
+-MUSIC
music1.mp3 (read only files for all users)
music2.mp3
[Code]...
I don't know which groups I should create. I'm having a hard time setting file/folder permissions. And I wanted to know how to set Samba so that it won't ask for a password when accessing public/group files, but asks for it when accessing private user files.

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.

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?

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.

i have 3 shares on my samba. i have users - user, manager and boss projects is RW to everyone reference is R to everyone RW to manager and boss Proposals is RW only to boss, no access to others However when boss logs in and creates a directory in projects share, the directory can only be renamed bu users and manager, and directory contents are read only for users and managers, even deletion / rename is denied. How can i make sure that when ever boss creates a directory in projects, it retains base folder permissions and is writable to user this is my samba file... i am using red hat 6.1 with samba 3.5.6 (i think)

I keep creating practice perl scripts in a linux directory using vi <filename> and need to chmod 751 <filename> before I can run it as I wish to. I'm sure there is a simple way to default my permissions or config them at creation, but I'm not familiar with it ayuda me por favor.

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.

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?

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.

I have an Ubuntu development server and a Windows 7 workstation. I use Windows Gvim to edit files on the linux server, over a samba connection.Saving files from Windows change the Linux permissions in weird way depending on the Windows app I'm using and also depending on whether there's a file extension or not.Here are some testsNo extension; Notepad2: 644 to 764
matt@mattserver ~ % ls -l testfile
-rw-r--r-- 1 matt matt 0 2011-05-28 07:09 testfile

I had set up a Samba server on SuSE linux a few years ago with a single shared directory. It has been running fine ever since, surviving various system upgrades and hardware migrations without ever needing to change the configuration (well, maybe once or twice). However, since a few weeks ago, it refuses write access to the share. It just returns NT_STATUS_ACCESS_DENIED when I try to create or write to a file. That's also what /var/log/samba/log.smbd says (nothing more AFAICT). It's the same for all clients, i.e. remote Win XP PCs or local smbclient.
The funny thing is that it allows write access immediately after rebooting the server, but after a while (the next day or so) it refuses again. Restarting smbd or nmbd doesn't change anything here. I suspect that this started after installing the latest security updates for OpenSuSE 11.2 on May 17th. The new packages were (according to /var/log/zypper.log):
xorg-x11-libXext-2379.noarch
libmysqlclient-devel-2315.noarch
openSUSE-build-key-2398.noarch
libpython2_6-1_0-2213.noarch
libpng-devel-2159.noarch
Somehow I can't see which of these might have an influence on samba. But I am absolutely and positively sure that I didn't change anything else. I logged into the server only once in months, and all I did was doing the updates using the updater applet.

I feel ashamed for even asking this, since it seems like there's about 3 samba questions here every day. However after an hour of searching, I keep finding strange variants that aren't what I need.
My Goal: Create a single file share on an Ubuntu Server - share it via samba to Windows clients that are on a domain with active directory. It sure would be nice if AD authentication would work - so users don't have to type in a linux user/passsword each time they want to access the share.
In my adventures, I've found the following items (which may overlap)
1. Joining the server to a Windows Domain
2. Turning the server into a Windows Domain Controller
3. Authentication with LDAP (still not quite sure how/what this would do)
4. Stuff with Kerberos
5. Lots of people bickering about Samba 3/4 & how it's impossible to make Samba a PDC.
I'm not sure if I need to make the ubuntu server a domain controller or not...all I want to do is create a file share and share it on the domain...I don't need to make the ubuntu server a domain controller for that, right? Maybe just a member? Maybe nothing at all?
I guess if I want to authenticate stuff correctly (or forward authentication requests? Not sure), I probably need to join the ubuntu server to the domain...I think.
But let's say I do join it to the domain...then how to I create a file share that is authenticated via active directory rather than a local ubuntu server account? I see a dozen guides on joining the server to the domain, but nobody ever mentions sharing the folder over the domain.
The lines are also blurred between joining Ubuntu to the domain and making it a domain controller. What should I keep an eye out to avoid in these tutorials?
I get lost between the Kerberos/LDAP/Samba/WinBind etc...and I have a feeling I don't need all of these for something this simple.

I'm using my Linux (SLES 10) server as a File Server at this point. I need to set File Permissions to nested folders differently to different groups. For example:
homesharedengineering* should be read only for groupA
homesharedengineeringadmin should be read & write for groupB Plus read only for groupA
homesharedengineeringautocad should be read & write for groupC Plus read only for groupA
I've been using Webmin and Putty to set permissions but Putty only allows me the Default Group, it won't allow me to set several groups on the same directory. Webmin seems to allow me to add multiple groups (Webmin --> Others --> File Manager --> Info & ACL tab will provide extended abilities) but when I add multiple groups, they don't seem to take effect? I'm wondering if my setup at the 'Share' level or at the hierarchy of my folder structure (unix based) needs to be set specifically?

now if i chmod this to 777 or use chown to change the owner this temporarily works but after a few moments it defaults back to its original permissions.
is there a way i can define the permission? i was thinking fstab but i can't have a mount point?

i have an old desktop that i have decided to use as a central point for localhost/website files. I have 2 laptops, a ubuntu and vista, and i want them both to be able to see the public_html folder on my desktop, and be able to create/update folders and files.
I have set up the samba sharing and that's working fine, but when i create folders using my laptop, they are not writeable to the desktop or other laptop because my laptop is the creator. Is there a way that I can set it so that whenever folders/files are created from either laptop, they have full permissions?
