I need to allow non-root users to read/write on an ext3 partition.
Below is the relevant output from fdisk -l
Code:
The partition in question is /dev/sda4 and it is mounted as /Data (setup during installation).
I created 3 partitions on my usb stick, one is vfat, one ist ntfs and one is ext4.And i formated them like this:
Code:
mkfs.vfat -F32 /dev/sdg1
mkfs.ext4 /dev/sdg2
[code]....
Anybody know how to make an ext3 or 4 partition start up at boot with only the owner and its group having read and write access permissions.I don't want 'others' to have folder access. This is what i have done. / etc/fstab:/dev/sdb5/media/Data ext4 owner 1 2 The folder starts on the boot since it has been allocated a folder as u can see. Next i changed the the ownership and the group ownership of the folder:chown johnny:johnny /media/DataThe problem is that other users can few my partition since 'others' have read access. How do i change that to zero access?

View 2 Replies View RelatedI have a netbook with Ubuntu 10.10 installed in it,and a Pc with also ubuntu 10.10 in it , but x86_64.
I want to copy some iso files and data from my user home directory on the netbook , to the user home directory of the other pc , using a 8 GB usb formated in ext3 with gparted in my pc.
One iso is a windows 7 one to burn then with K3b , as i need to have windows installed in that box. Also of another iso that i have to burn too (windows 7 recovery disk) , and 3 anti-virus trials for windows.
As the usb is owned by the root (or more properly the mounting point,no?), and i can't use my user to copy data to it i usually do :
Usually , what i use is "sudo nautilus" then go to the place where is the data , copy it , and paste it then in the usb. Then in the other pc i do a chgrp and chown to the iso or file.
But , perhaps this is not the better approach. I have investigated a bit , and i think that i have found a better way , but i have some dudes.
The method is change the owner,group and permissions of the mounting point:
Code:
cd /media
ls
umount /dev/sdb1
sudo mkdir usb
[Code].....
If i do this steps in both computers, with each user,in the netbook i can copy the iso to the usb (as fox can write to the mount point of the usb ), but can the other user in the pc 'mulder' read the iso , so be copied to /home/mulder, and then be able to burn it in k3b with success ?
I suppose that having 766 , it should be able to read it , but would have the own of the file ?
How important is not to only be able to read it , but also own it ?
I suppose if the user ID is the same , wouldn't be any problem ,as each ubuntu would supose that the file is owned by their user.
Perhaps the user name change,but if the ID is the same , the user is the same for ubuntu , not any different, no ?
I own a particular file on a Linux system. I would like to give 2 groups (accounting, shipping) read access and only read access, and 3 users(Mike, Raj and Wally) write access and only write access. How can I accomplish this?

I have a Mac Pro running Leopard OSX. The graphics card an NVIDIA 7500GT or driver has failed. It was suggested elsewhere that I change the relevant kext files to filename.kext.old, which I did, now when I try to boot start in OSX I get a message in various languages telling me to restart. I have tried booting in safe mode and from original Installation CD. In Safe Mode I get the same multi language splash screen, from CD I still have the graphic card problem, screen freezes and artifacts appear. So I boot up straight into CLI by holding down CMD-S hoping to be able to change filenames back but it says device read-only.

We have a xfs partition over a hardware RAID that stores our RAW HD Video. Most of the shoots are 50-300gb each so the linux cache has a hit-rate of 0.001%.
I have tryed the sync option but it still fills up the cache when copinging the files. ( about 30x over per shoot :P )

I have an Iomega External Hard Drive 1TB. Problem: Unable to write to Ext3 Partition. How I got here: Started off with going into windows and shrinking it's current NTFS partition down by 50GB. Then used an Ubuntu LiveCD to gain access to GParted and with that 50GB free I formatted it with an Ext3 system. It does this no problems. I then can't write anything to this partition? I've tried doing "chmod 777 /dev/sdb2" but it says Operation not Permitted.
EDIT: Need to be able to use it on YDL 6.2 on my PS3, YDL doesn't have NTFS write support and I want to transfer files larger than 4GB rendering Fat32 useless. No I'm not able to re-size or compress this large file.
I have a dual boot system and am trying to be able to access all partitions in both OSs. I've tried some windows software that are supposed to be able to read linux partitions, but without luck. Essentially, my linux OS (rhel) is represented as an LVM partition (within the logical volume is ext3). In windows (7), file viewing programs see the partition as "raw". Is there any software that can read LVM in windows?

Is the an accepted fix to giving users read/write privileges for all usb devices?
View 4 Replies View RelatedI have shared two external harddrives via samba on ubuntu, but only I can access it. The reason being is because I have logged into linux, and become the owner of the external hdd's. On the permission properties, I can see that the group I have created every other user under has "No Folder Access", and if I change this it reverts back instantly. So frustrating, I've tried to chmod it which hasn't done a thing. The owner of the external hdd's seems to be the only person who can access it over samba.Is there anyway I can get normal users to just read and write to external hdd's?
View 9 Replies View RelatedI've been reading for a while about samba but I haven't found a solution to my problem yet.I'd like to know if, the configuration I have in mind, is possible at all ("security = user" is what I'm using now).I want a directory to be:
1) read only for guests and some UNIX users;
2) write for some other UNIX users.
The advantage of this configuration would be that every single user in my LAN (with or without a UNIX account) would be able to read the content of the shared directory Music and I (UNIX user andrea) could manage the folder directly trough samba preserving the correct owner/group and permissions on the new files/folder created.
Notes about my configuration above:
1) as it is now every user gets authenticated by samba as nobody so even I (andrea) cannot write in it;
2) commenting out the line "guest ok = yes" I can authenticate as "andrea" and write in it but guest access is not possible any longer.
With the release of CentOS 5.5 ext4 is considered stable in this distribution so I decided to migrate to it. Luckily I started from migrating fresh server with CentOS 5.5 using some instruction I found on the internet. I think I shouldn�t say, that I screwed the whole thing up ;) After about 6 hours cursing, kicking, and crying I solved the task and figured the correct sequence of actions. The small problem with migrating root partition is that you can�t unmount it BTW.
During migration task, I found, that CentOS 5.5 rescue mode is somewhat broken a little in terms of ext4 support. It can mount ext4 partitions successfully. But its e2fsprogs package (tune2fs, e2fsck etc.) doesnt see ext4 partitions and say, that superblock is corrupted on a partition once is converted to ext4 (at least it did it for me. May be I should force filesystem type with -t ext4 switch?). Keep in mind, that if you screw your system up too badly, you will not be able to run tune2fs and e2fsck on it from rescue modeBut you will still able to mount it if it is not corrupted badly. In all below examples,Boot your system normally and login as root. Upgrade kernel if you wish (I usually use yum upgrade to upgrade all on new machines). Then upgrade/install some other packages
I just wanted to post this in case it helps anyone else. I have all my personal files (photos, documents, etc.) saved on a separate ext3 partition (so I don't have to worry about them on new installs, etc.). When I tried to delete files, however, I always received the message: "Cannot move file to trash, do you want to delete immediately?".
After much searching and failed fix attempts (mostly unnecessary messing with fstab), I found this post, which is now archived (or I would have replied there):ttp://ubuntuforums.org/showthread.php?t=759544. And frediE's solution, with a couple tiny modifications, finally solved the problem! (So huge thanks to frediE! ). irst, I found my user id, which is 1000, by going to the System > Administration > Users and Groups menu, selecting my user name (e.g. jnewm), clicking "Properties", andselecting "Advanced".
Second, I created a folder on the root of my partition called ".Trash-1000". (I may have needed to use "gksu nautilus" from a terminal to create the folder, I don't recall.)Third and last, I navigated to the root of the partition in my terminal and ran: sudo chown -R jnewm:jnewm .Trash-1000. Followed by: sudo chmod -R jnewm .Trash-1000 (I doubt this second step was necessary, but I'm listing it just in case). (confirmed unnecessary)
I have a flash drive that I use to sync my work- and home-computers. Rsync has occasional issues syncing between FAT32 (which I use on my flash drive b/c it's universal) and EXT3.
I decided to create an EXT3 partition on the flash drive in an attempt to alleviate the rsync woes. My problem is that when I create the partition using GParted, Ubuntu auto-mounts it with Root as the owner. I had GParted check the drive, and it found no errors to repair.
One other weird thing is that the EXT3 partition shows 84.7MB being used immediately after creating the new partition.
The FAT32 partition mounts fine, is read/write, and only shows 4KB used after the new partition scheme.
I tried doing new partitions a number of times, with EXT2, EXT3, and EXT4 just to see if that mysteriously made a difference. Each time that partition would mount w/ Root as owner.
I was wondering if anyone knows how to read write a ntfs partition on thats on a separate linux machine ?

Is there an easy way to read/write to a mac partition inside ubuntu 11?
Any graphical ways to mount / umount?
I've hit a wall here; I'm attempting to find some way by which to view files and cd into directories on a device mounted read-only. So I need the permissions to read, write, execute (and the same with directories), but chmodding is out of the question because I don't want to alter the drive one iota.
I guess what I could do--what I was thinking of initially--was to dupe the whole drive and then mess with permissions. This wouldn't affect the original (actually I'm working on a duplicate of the original, but I'm treating it as if it were the original) but I was hoping for something that would maintain data integrity. This is a forensic application and not altering the data is very important.

View 9 Replies View RelatedI'm setting up Ubuntu Karmic on my sister's old computer for my nephew, he's quite young so my sister asked to install some content filtering. I'll first setup an OpenDNS account and I've installed and managed to get dansguardian and squid working on a virtual machine to try it out. so far it's working pretty well, but I need to secure it form the inside out.
I was thinking of blocking specific outbound ports so he could not bypass the proxy. because by default the firefox configuration can be easily changed. so I have a couple of questions.
1. is it possible to block outgoing ports on Ubuntu?
2. is that the best method?
3. is there anything else I should be aware of to prevent subversion?
lastly, this question is probably unrelated to this board but I've set up a cron job to update a dynamic ip with OpenDNS, the problem is that the password is in clear text in the user's crontab, can I play with permissions? is it possible to run the job under a root account and deny read/write access to a normal user?
I need some assistance mount a UFS2 partition as read and write. if its not possible, then I may have to copy a few hundred GBs of data. Currently using the command: Code: mount -r -t ufs -o ufstype=UFS2 /dev/sdb /Data Thats just read only.
