Using chown as root, from the userb directory and as follows /home/userb chown -R userb:users /home/userb/* has changed the ownership of direcories, subdirectories and files of all other users. There are too many of those but only 4 users to restore the proper ownership and I do not know bash, can someone give me a bash script to do the job, avoiding the -R switch?

I am running a shell script as the user "redhatuser01" and this script creates a files in the home directory of another user "redhatuser02" (/home/redhatuser02/sample.txt) but the ownership of this file is currently "redhatuser01". How can i change the "ownership of this file to the user "redhatuser02"? (My constraint is that I cannot sudo as redhatuser2 and create the file).
View 5 Replies View RelatedI've implemented a program URL... which reads digital IF data from a radio receiver through a named pipe, measures power levels, and sends the result to stdout. The program is interactive; there is a thread that reads from stdin to watch for commands, a thread that constantly either reads data from the named pipe or throws data away, and an array of processing threads. The program uses GTK+extra to plot the signals. The IF data stream bandwidth exists at the limits of today's technology (is very very fast).
Problem Statement:The program works fine with a few bugs. I've learned since I've made it that using global state variables to coordinate threads isn't a good way of doing it. I also only had knowledge of mutexes and polled the state variable instead of using other methods.My reimplementation will use the following:
- One "Stdin Command Monitoring" thread
- One "Get data from named pipe" thread
- One post-processor thread
- N Processing threads
All threads are alive during the life of main()There are N buffers. Data will come in from the named pipe, and the "Get data" thread will write the data to an "available" buffer. When the buffer is full it will be marked as "full". There will be N processing threads, one for each buffer. When a processing threads' buffer is full, it will process the buffer and save the result to a final buffer. At the end of a number of averages, the post-processor thread will perform a final process on the final buffer and send the results to stdout.

I have my hard drive arranged with a single large ntfs data partition and a number of smaller partitions for /home etc. Here's the line in fstab:
Code:
/dev/disk/by-id/ata-SAMSUNG_HD103SJ_S246J9FZ806954-part2 /home/shmuck/data ntfs-3g users,gid=users,fmask=133,dmask=022,locale=en_US.UTF-8 0 0
But the ownership for that directory is root and I can't change it for some reason, using this line:
Code:
sudo chown -R shmuck /home/shmuck/data
It just doesn't do anything.
The previous writer gave instructions for editing fstab. He said to enter something like the following line in fstab:
/dev/hdb1 /media/harddrive ext3 defaults,errors=remount-ro,users,user_xattr,user 0 0
My partition is: /dev/sda7.
I created a folder in media: /media/8g
The file system is: ext2 (Do I need the "defults" instruction? What does this do?)
errors=remount-ro (I think I understand this)
[Code]....
He also said, after this was all done, to enter the command: sudo mount /media/[my new partition]
Since it's already mounted? What does this command accomplish?

View 9 Replies View RelatedI recently installed ubuntu 10.04 on a new system and installed Virtual box to run a virtal Windows environment. I also added an additional 2 Tb hard disk to the system that will be used to store the virtual machine(s). I managed to add the hard drive in ubuntu and it is recognized as DriveD_ in the Media folder (don't ask me how i did it ... trial and error). I am the owner of this folder. In the media folder there is also a folder named DriveD, and this is an empty folder. The owner of this folder is Root. When I start Virtualbox, Windows starts up normally, and recognizes the second drive D (which I partitioned and formatted before). After closing the Windows, Virtual box and Unbuntu, the mystery begins. When I start Ubuntu, the DriveD_ folder is not visible and I cannot start the Windows virtual machine (error message: VD: error VERR_FILE_NOT_FOUND opening image file). When using Tux Commander, I do not see DriveD_. When I use Nautilus to go to the same Media folder, both folders are visible (DriveD and DriveD_). When I open Drive_, the Virtual machine files are present. After doing this, I can start Virtual Box and start Windows normally. I think it has someting to do with the ownership of the second hard drive that I added (maybe I made a mistake attaching it in ubuntu?) Has anyone experienced this before?

I've recently started setting up a new wordpress install on a new dedicated server. The system is installed on a linux debian 5 setup and running on apache.Having only ever run shared hosting before this setup is a much bigger leap than expected, but after a couple of weeks doing bits here and there I've finally got the setup running, and all appears ok.My issue is as follows:On the server the default owner of all the installed folders is "root"In order to allow media uploads, plugin installs and upgrades and wordpress auto-upgrades I've had to Chown the owner of the entire wordpress directory to the server as follows:Chown -R www-data:www-data /usr/share/wordpress/
Can anyone tell me if this is actually secure? (clearly if the server is compromised the folder would be writeable!) If not would I be better changing the owner back to root (or even creating a new user for the wordpress folder?), then chown just the uploads, theme, and blogs.dir folders to allow media uploads, upgrades, etc from with the wordpress, and then only chown the entire wordpress install when upgrading or installing new plugins, themes, etc.?Just a bit lost when it comes to the ownership of these folders as changing these ownerships is the only way i can get the system functioning 'correctly'
NSA's Guide to the Secure Configuration of Red Hat Enterprise Linux 5 recommands restricting device ownership to root only.
So my question is why should we restrict device ownership to root? And what does device ownership mean anyway in Linux?
I just got a 1.5 terrabyte Western Digital My Book 1110 external usb 2 drive. I used Gparted to reformat the drive to ext3. The problem I have is I can't change the file permissions for the drive because it says the drive is owned by root. I can't back up my files into the drive because it won't allow me to. I am using Jaunty Jackalope and got this drive to back up my files so I can feel comfortable in upgrading to Karmic Koala in case there are major problems with the upgrade.
I know someone out there in the community can tell me the commands to use in the terminal to let me gain ownership of this external drive from root so I can copy my files into it. the entire drive itself is seen as /dev/sdb One meg of the drive is unallocated and the part of the drive that I reformated is seen as /dev/sdb1 my personal files are owned by the name of dave
In order to get my PIC programmer to work through Piklab, I have to change the ownership of the /bus folder to myself;sudo chown MYUSERNAME -R /dev/bus.The ownership of the folder then reverts back to root after some time.Is there anyway to make it PERMANENTLY under MYUSERNAME ownership?

using Pysdm as a gui for fstab - but so far I have only found out how to allow other users to mount the volume not own it.

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.

I've created a share using Nautilus on an Ubuntu 11.04 machine and can access it OK from both my Win 7 pc and partner's WinXP machine. We both have Ubuntu accounts and use those to access the share. When an Excel spreadsheet is saved on the WinXP machine the ownership changes and it can then only be opened read-only on the Win7 machine. A further complication could be that the Win7 machine has OpenOffice and the WinXP has MS Office. I'm guessing that XP + Office doesn't really care about or see the permissions, but Win7 + OpenOffice does. Should I be using the share with the same username from both PCs? Is my whole approach misguided?
View 1 Replies View RelatedSo, I've done a lot of stupid things, but this one ranks pretty high. So I'm looking at files here and there, fooling around and tweaking things if I can, but after a while, I get sick and tired of having to fiddle around because a file's owner is root. So, completely ignoring the fact I could start an x session as root, I perform the following command:
chown -hR MY-USERNAME / I'm thinking to myself, "Oh look at me, I'm so smart" until I turn off my laptop for the night and come back this morning, and ubuntu (10.10, 32 bit) says it could not change ICE authority (or something like that) and a few more error messages. Then, I boot into the recovery console, and again, not even bothering to think anything through properly, I chown everything back to root, then chown my home folder back to me. Anyway, I still get the error message, execpt now I can't alt-c to close the first windows that talks about the ICE authority file.
One of my friends has an ubuntu partition, so I can ask him about certain ownerships, but that could take a while and I don't know where to start.
