Ubuntu Security :: Changing Permissions Of Files To Reflect Their New Folder?

Jan 4, 2011

I have a shared folder set up that allows all users on the computer to have access to all the music on the computer. In the folder with all the music the group 'music' has permission to add and delete files and all users are members of 'music'. This should allow all users to have complete access to these files, however, when I add files to the folder they retain their original permissions and do not take on the permissions of the folder. I could change the permissions of the files to reflect the folder every time I add a cd. But that is annoying. What I am wondering is if there is any way to make files automatically reflect the permissions on the folder they are moved into.

Software :: Changing Permissions Of A Folder?

Oct 4, 2009

I've compiled my own code as root (long story why) anyway I now need to switch this to a normal user to compile. So I did a simple copy/paste (using gnome/debian lenny) to my home/user. I then logged in as used to see the folders with a padlock and permissions for root only. So I logged back in as root, change permissions to the used, check they were all ok, logged back in as user, and it still says owner root, even thought when I log in as root it shows user as owner.

Ubuntu Security :: HD Attack Into APT Manager And Folder Permissions

May 24, 2010

I may not be a code worrior, yet I have been a Ubuntu convert from Apple for about 3yrs now. Since 1984-2006 now hackers or viruses. And Until now Ubuntu has been clean, well I have been good with repos, etc.

1. Recently I found "Odd" behavior with my Amarok 1.4 player, ffmpeg, winff.

2. During a Synaptic upgrade there were some "unauthorized changes". I have seen this before due to some of my software, so I ignored it. . .

To my bewilderment, "It" erased Amarok 1.4 player, ffmpeg, winff, all image kernels, claimed domain over my system permissions, and external HD. B4 I shutdown, downloaded LUCID 10.4. . . restarted, then copied over all info possible to minimize a complete delete of my system. Upon restart, indeed all kernel images were gone, Only live CD allowed me access to repartition my HD.

NOW. I have Lucid running, and have been denied access to my external HD and partitioned (internal HD). I used Nautilus to copy over files to my internal laptop HD, yet permissions continue to be an issue. The INFECTED FOLDERS are owned by "User 999-user#999. I must micro manage every folder and file to gain "partial permission". The dialog box stutters and never allows me to go down to "Root"

Ubuntu Security :: Change Permissions Of Folder's Content?

Feb 22, 2011

Recently I've tried installing Calibre from the Software Centre, but it seemed to be glitching as when I press Update Source, the 'In Progress' icon shows up, but when it finishes nothing changes - the Update Source button is still Should I report this?Anyways, I've installed Calibre from their website to .calibre in Home Folder. However, the folder is 'locked' as it requires root priveleges and I can't drop files there without being the admin. I'd like to reduce 'open as root' files to minimum, so I was wondering if there is a way to change the permissions of all the content in one operation, preferably using GUI, and not the terminal?

In addition I've noticed that other folders in my Home Folder like Pictures/Wallpapers require root privileges. This is really annoying as when I 'experiment' with Ubuntu I use Live CD to make sure I don't screw up the main system. When I do I can't open some files from hard disk because of those root inconsistencies

Security :: Folder Permissions To Avoid File Upload By Http User?

Feb 24, 2011

However, configured a website on a dedicated server using WHM/cPanel. The site was uploaded using the master account for the website.

The security issue is public users are able to upload files on to my server via the website. They could even access the root and execute whatever they want on the server.

I have consulted with 2-3 Linux experts. According to them, the PHP user has rights to execute anything on the server or upload & store files in whichever folder they want.

Can I protect my folders to avoid file uploads via the website. The application has security vulnerabilites. However, I want to prevent hackers to enter my site until the vulnerabilities are fixed.

Ubuntu :: Safely Change Permissions For Folder/all Subfolders & Files?

Apr 1, 2010

I just installed Karmic, but I can't copy an old user's home folder (/home/oldusername/) because everything is owned by root.I read but I'm concerned about messing up the system or the files in that old user's folder.So, how do I adjust the permissions of the files in /home/oldusername so that I can use openssh to copy them over my home network to my other computer? I have the ssh part figured out, but the files will not copy to the laptop due to permissions.

Ubuntu :: Inherit Parent Folder Permissions When Copying Files ?

Mar 28, 2011

I do have an Ubuntu Headless server which is running Samba on it. My mp3 file collection resides on that server on is being share.

So far, no problems connecting to that drive and writing from my Windows box on that share. But if I use my main laptop, which runs Ubuntu Lucid and download an mp3 song from Amazon, the moment I move that to the share, I got permissions problems from the Windows machine. This is clearly a permission issue with group and others; the song is being created on the share without read and write permissions to others or the samba group I created.

My question is. How can I make this process simple or automatic, when moving songs to the share? I don't want to go there everytime and run ...

Code:

Which was basically how I reset or fixed the problem.

I've read about umask, but not sure if that applies here or not, because I'm not creating the file but moving it.

OpenSUSE Network :: SAMBA - Changing Default Permissions On Files And Directories Created From Windows Clients

Mar 9, 2010

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.

Programming :: Test Permissions On All Files / Folders Into A Folder Recursive?

May 16, 2010

Way to test permissions on all files/folders into a folder recursive, then if those are not user:user then do :

Code:
chown user:user thatconcernedfile

The problem with that

Code:
chown user:user -R /folder

is that it is doing changes on file permissions whihch are already ok. If you wanna maintain a specific permission on a folder this is really not good this :

Code:
while [ 1 ] ; do
chown user:user -R /folder
# /folder contains 6.0 Tb
sleep 2s
done

Ubuntu Security :: How To Change Permissions To Allow EXE And JAR Files

Apr 4, 2011

I've been using Ubuntu for a few years and I am having issues trying to load .jar files and .exe files in Wine. I keep getting an error message that says my computer doesn't have permission to load these files. I've done some research and found people saying to enable the file as executable in the files properties, to enable executable in the permissions folder, and to allow source code on the Ubuntu Software screen, but whenever I try to check these boxes, they immediately revert to having a line through them instead. I remember when I was running Ubuntu a few years ago I was able to completely disable this restriction in terminal, but I can't remember what I did.

Security :: Set Permissions For Multiple Groups To Have Different Levels Of Access To One Group Of Files?

I am setting up a samba server to operate in a windows AD domain. I want to set permissions for multiple groups to have different levels of access to one group of files, and it looks to me like unix permissions will not do that? I always hear about how robust linux is, and it seems to me that their file permissions model is WEAK compared to microsoft's?

Security :: Group Write Access For Newly Created Files / Directories Without Changing Umask

Apr 3, 2009

I have several directories, each owned by root and a group of the same name,By setting the sgid bit, I made sure that newly created files and directories are owned by the correct group, and that directories have the sgid bit set too.On each newly created directory or file, the permissions are set to 755. This is because this is the default umask, and I cannot change a users umask. I actually only want files created below a particular directory to have group write access, inheriting this behaviour to newly created directories properly.I'm not on samba or NFS, I have to do this for SSH users.The filesystem is ext3.I started to fool around with ACLs, but couldn't find what I was looking for.

Ubuntu :: /dev/lp0 Permissions Keep Changing?

Aug 26, 2010

The problem is whenever we reboot the system the permissions of / dev/lp0 (line printer) is changing. So every time we are changing the / dev/lp0 permissions through root using chmod 777 /dev/lp0

Is there any smooth solution for this? Why the /dev/lp0 permissions are changed with every reboot?

Ubuntu Security :: Changing Password Seem To Be Potential Security Hazard?

Aug 3, 2010

I already posted a topic similar to this concerning the Desktop OS version, but this deals with the Netbook because unlike the Desktop, the Netbook is less cooperative. Allow me to elaborate: Today (or rather yesterday since it's not after midnight where I am), I changed my password because I was hopelessly confounded about how to get my Wireless Network card up and running after it had been installed and I was allowing my dad to use it. This issue has since been resolved, however...

When I chose my password during the original installation, there was no mention of it being "too simple." This is where the Desktop OS and the Netbook OS differ. The desktop will let me change it in the terminal without any errors. The Netbook will not. When I've attempted to revert it back to the original, it will not let me do so in the User Profile or in the Terminal. The Passwords and Encryption Keys application also does not appear to help.

So now even after I've changed it to a different "complicated" password I am still prompted to insert two different passwords since I changed my user password but I am unable to change the password I input during the installation. A bit screwy methinks. This is extremely important. I'd like to know how to change the original installation password.

If I can't change the main password on my laptop then this is a serious potential security breach just waiting to happen (especially since it's on a laptop and I will be hauling it around with me) and I will most likely install a different OS if this isn't resolved --- It would be very unfortunate since I spent the whole day fixing it and I really enjoy the interface. Luckily I can live with this on my Desktop since I'm not going to be hauling it around with me everywhere when the school year starts.

Ubuntu Security :: Configure The Share And Folder So That The Win7 Client Can Create Files And/or Folders In The Share?

Jan 15, 2010

I've just installed Ubuntu 9.10 and Samba 3.4. I've shared a folder and have accessed the share from a Windows 7 client. However, I've struggled to configure the share and folder so that the Win7 client can create files and/or folders in the share. Kept getting Permission Denied errors. Finally, (using Webmin) I set the permissions on the file folder so that "Other" had write access. I don't understand why this was necessary (and how unsecure this is). I already had the write access checkbox ticked for "User" but it wasn't enough.

Ubuntu :: File Permissions Keep Changing On USB Drive

Jan 25, 2010

I use a USB drive to store most of my personal and work files, and I use it both at home and at work (two different machines, both running Ubuntu). The drive is encrypted, and is accessed using TrueCrypt (the entire drive is encrypted as a device rather than an encrypted file on the device). The TrueCrypt device is formatted as ext3/ext4.

I have a problem with certain file permissions being changed to read-only (rw-r--r--) after mounting the drive. This happens after I have used it on one computer, and then I mount it on the other. Even though I have been setting write permissions to all (chmod -R a+rw *) to get around this problem, when I mount on the other machine the write access is gone. I don't want to keep manually changing permissions; I would like the file permissions to stay as I set them.I'm using the same version of TrueCrypt at work and at home. I'm running Ubuntu 9.04 at work, and 9.10 at home.I do have different usernames on these computers, and I suspect that is the problem (but don't see why this would change file permissions for all users).

Ubuntu :: Changing File And Ownership Permissions?

Jan 1, 2011

I installed Ubuntu from the alternate cd a few days ago to save space and resources on a very old laptop. (install command line, then add what I wanted) But I have struck an interesting problem with file permissions. Various programs like synaptic, leafpad, pcman, Banshee, all require I enter the root password to execute them (or sudo command from terminal). I want to change synaptic from root ownership to sudo and leafpad etc to execute without using the sudo command in terminal. I could get comments on the commands before I execute them in terminal and if I am introducing a security problem, as I am still learning bash. $ sudo chown sudo:sudo synaptic

I would still be asked for my sudo password before being able to open synaptic? As in standard Ubuntu instead of root password.$ sudo chmod 777 leafpad pcman Banshee All users could open these programs from the menu? I have my admin account and a general account which I use for everyday things like surfing the net and listening to music.

Ubuntu :: Usb Stick Is Changing File Permissions?

Apr 8, 2011

I have two computers (one at work, one laptop) that I use daily. Both are running Ubuntu 10.04. I frequently use a usb stick to transfer files from one to the other. Somehow, every time I do this, all files get turned into executables (as if I did a chmod a+x on them...)

This happens every time I use the usb stick. I've reformatted the stick, but still this problem persists... anyone have any ideas on what is going on? It is really getting annoying to have to zip up folders so this doesn't happen...

Ubuntu :: Directory Automatically Changing File Permissions

Jul 12, 2010

Is there a way to have a directory automatically change the permissions of a file that is written to it? I have a program which saves files to a directory, and gives those files read-only permissions to members in the group. This is a problem, because other users of my computer need to be able to edit these files. The directory itself has rw permissions for group members.

I guess what I am looking for is a way for the directory permissions to "override" the permissions the program is trying to save the files as. For example, if the directory has "rw" permissions for the group, then any file saved to it will automatically get the same permissions, regardless of what the program writing the file is trying to do.

Ubuntu :: Changing Icon And Setting User Permissions?

Oct 29, 2010

I tried to place a mono icon in usr/icons/etc but I didn't have the permission to do so. I tried to change my user profile to Admin, thinking I could go back to custom, but that hasn't and it isn't allowing me to go back to my previous setting.

Within minutes of being an Admin user I noticed I couldn't even unmount something. I really need to figure out how to change my profile back to default.

After that has been dealt with, I would like some guidance on how to gain root access to put my icon where it needs to be.

Ubuntu :: Server Not Accessible - Changing Permissions On Folders?

Jan 3, 2011

We have a development server not accessible to the public used for testing which was setup for us. When attempting to have my PHP scripts upload an image to a folder, I have to CHMOD the folder to 777. Ideally, when a folder is created it has permissions set to 755 - I want to be able to upload to them. Is there a way to change permissions to allow the PHP scripts that run to be able to write to a folder? I know it has something to do with owner or group, but I don't know where to start.
