General :: Umask And Permissions - Has Umask 007 Bad Side Effects?
Mar 16, 2011My Debian system has by default umask permissions of 0022, which I never liked. One user can read all the files of another seems very insecure to me.
I am planing to set it to 007, so that user and group have rw but all others have none.
Are there any side effects to that? I have noticed from a trial I did where I was changing permissions on the filesystem that some system stuff in the OS does not work anymore, if "others" have no read permission anymore, so that is why I am asking.
And why are chmod / umask permissions sometimes stated as 4 digits? What is this "all" group in the end? Isn't that already covered by "others"?
General :: Umask And /usr/bin/umask ?
Apr 25, 2011Not sure if this is the right place to ask this question. In Solaris we have umask (shell builtin) and /usr/bin/umask. However I could not find /usr/bin/umask in Linux.
I want to know the difference between both and how can we achieve the functionality of /usr/bin/umask in Linux as its not there...
General :: Umask Change ?
Jun 7, 2011I have logged in with root user
My systems Umask value was 0022.
Code:
So i decided to change it to 0077 and observe the system for some time. so i edited /etc/profile and added
Code:
at the end of file
rebooted the machine.
But the umask is still showing as 0022
After the first attempt is failed I tried changing it using below command.
Code:
Validated it.
Code:
rebooted the machine but the umask is still showing 0022
So at last i have to modify /etc/bashrc file and add umask 077 at the end of the file.
How would i make it in general for all(Even for non-root user) and not just for bash prompt.
General :: Changing Default UMASK Value?
Jan 15, 2010I am attempting to modify the default umask value under all accounts on my linux system to 002. This will hopefully allow both the account and the account's group access to the created files.
I have modified it within /etc/bashrc, however it seems to be making no difference on this default value. The files I create through "File Browser" all have the access rights set to 600.
Is there any error here, as all evidence I can find on the internet points to the bashrc file.
General :: Get Umask For All Users Using Script?
Feb 16, 2010I am writing a bash script for auditing a Linux System. One of the points to capture is the umask of the users in the system.
Though a 'umask' command executed by the respective user gives this value, i am not sure how to get this in a script, which would be run with root credentials. This my be pretty easy, but i am not sure how root can find this for say 'user-x' (except say peeking into /etc/bashrc).
umask doesn't seem to accept username argument like the 'id' command does...
General :: Set Default Umask For Users?
Jan 4, 2010I think the following code is trying to change the settings inside the file:

sed -e "s/002/$CISum/" -e "s/022/$CISum/" /etc/csh.cshrc-preCIS > /etc/csh.cshrc

But, what if i only want to check what the settings are inside the file, but does not want any changes to the file.

General :: Umask Change Not Taking Effect
Dec 28, 2009I have 2 Oracle users that generate .tmp files under /var/tmp. By default, the files have the permissions 644. Now, a need has arisen whereby the files created by these users have to have the permission bits as 664. Obviously, I changed the UMASK value for these users from 022 to 02. But the files are still getting created with 644 as the permission.
I tried restarting the application as I read that a relogin is required for the UMASK change to take effect. Even that hasn't helped.
General :: Apply Umask Settings To An Account That Doesn't Log In?
Aug 4, 2011On my Ubuntu 11.04x64 server, I have service accounts running which do not log in and do not have home directories. These service accounts are responsible for running processes which are invoked as services.When these services created new files, I need them to be created with the permissions 664 (UMASK 002).I edited the /etc/profile umask setting to reflect this. I see that now my user account creates files which reflect this new umask setting, but the service accounts do not when I manually created files using their accounts (sudo -u serviceaccount touch newfile).

View 1 Replies View RelatedGeneral :: Change Umask For Files Created In Ext2/ext3
Oct 28, 2009I have ext3 partition mounted on /mnt/shared/ as follows
Code:
Permissions above are of the actual mounted fs.
Goal is to have all files created on the fs
1) to belong to group 'users'
2) to have this groups permissions set to rw (rwx for directories) so that all users who belong to group 'users' have full read/write access to data and everyone else to have only read access.
Now because of setgid bit (s) in group permissions every file created has group 'users' and additionally setgid bit is set for directories. Because every users umask by default (on my system) is set to 0022 all created files will have permissions 644 for ordinary files and 755 for directories.
Net result of above means that users A and B who both belong to group 'users' won't be able to modify files created by the other.
So how can I make files created on the fs to be created always with umask 0002 WITHOUT changing default umask for users that is used elsewhere (like in their home directory) ?
General :: Setting User Mountpoint Permissions In Fstab Without Uid / Umask
Jan 30, 2010I'm struggling to understand an aspect of mounting and mountpoints with /etc/fstab. There is a large number of sites and threads that make recommendations using things like uid, gid, umask, and other options. These methods, however, which I've used, are file-system specific, useful only for filesystems such as (V)FAT and NTFS that allow them.My current situation is that I am mounting partition /dev/sdb5 in, let's call it /media/myMount. My goals:Mount this partition automatically upon boot using /etc/fstab...The partition should be fully accessible only to a specific user or group.What I've done is create the mount point in /media:
If user michapma were to carry out the mount, I believe it would work; however, I want the mount to happen automatically during boot. So, how can I achieve my user (or group) permission goals for this and any other such partitions using fstab?The manpage for mount has been helpful, but after reading many tutorials and forum threads, the only way I know how to do it is to have the user do the mounting or rely on the file-system specific options.
General :: Concept Of Umask - Default File And Directory Permissions
Apr 14, 2010I 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?

Ubuntu One :: Shows One "LOCAL MACHINE" Entry Which Doesn't Go Away
Mar 31, 2010However, in the dialog which shows the connected computers to the account, I found that there are a lot of old computers (previously linked from my home computer, office computer, Virtual Box installations.

Oct 27, 2010after installing openSuSE 11.3 i was thinking a bit about security. I read, it's a good idea to set umask of users to 077 . I'm unsure now, where to do this, cause there are different locations offered in the web:
/etc/login.defs
$HOME/.profile
/etc/profile - umask would be valid for root too.
And for my understanding:
- Is it wise to set root to umask 077 too or could this lead to negative effects on my system.
- Is it even senseless to umask the normal user to 077 if there is just one desktop-user using my system (myself ).

2) Use the umask command to change your file creation mask such that,by default for new files and directories you create, no permissions are taken away from the 'user' (owner), write permissions are taken away from the 'group' (group owner), and all permissions (read, write and execute) are taken away from 'other'. Take a screenshot of your terminal window showing the results of this step.
3) Use the touch command to create a new file called testfile. Use the ls command to display the contents of your current directory in long mode. Take a screenshot of your terminal window showing the results of this step. Ensure that the directory listing for testfile is completely visible in your screenshot.
4) Use the chown command to change the user associated with testfile (the owner) to cint201. Take a screenshot of your terminal window showing the results of this step.
5) Use the chgrp command to change the the group associated with testfile (the group owner) to users. Take a screenshot of your terminal window showing the results of this step.
6) Use the chmod command to change the permissions for testfile such that the 'user' (owner) permissions are set to read, write and execute, the 'group' (group owner) permission are set to read and execute, the 'other' permissions are set to grant neither read, write nor execute, and finally set the SUID bit for the file. Take a screenshot of your terminal window showing the results of this step.
7) Use the ls command to display the contents of your current directory in long mode. Take a screenshot of your terminal window showing the results of this step. Ensure that the directory listing for testfile is completely visible in your screenshot.
