Ubuntu Security :: Add Acl Option To Fstab?
Feb 23, 2010
I've got a partition, let's say sdb6, which is one of the partitions of my second hard disk.On boot ubuntu only mount my boot partition, let's say sda2, which is on my first drive.Once ubuntu started if I want to mount a partition I usually click on it under the Places menu and an authorization is required.As I would like to add acl to a partition following this thread

http://ubuntuforums.org/showthread.php?p=8787962
I've tried to add acl option to my fstab, but my /etc/fstab doesn't have any info of any of my partitions and it originaly looks like:
Quote:
# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name[code]...
My goal is to mount/unmount any partition with acl loaded and graphically ,but I reached my limit on my linux knoweledge.

I have since quite a long time the problem that files using special characters in their filenames are not displayed in various applications. In console or Thunar I have a special "white questionmark in a rhombus" sign for every special character. It is an XFS partition. I have read a few times that this can be solved by using the iocharset=utf8 option in /etc/fstab, but this option is not recognized and the mount inhibited.
I used other options: utf8 as well as nls=utf8, but that was not recognized neither. What option do I need to specify to enable utf8 for XFS ? Samba works. That means I can play an MP3 file in Windows exported from the XFS disk using Samba, although the special character is then shown as "_" in Windows..

I have already started a thred here about RAID failure: RAID5 failed, system drops into limited single mode - openSUSE Forums
I was not able to boot the system until I commented /dev/md0 in fstab
Why is it so?
This is just a files sharing partition, it is not a system partition.
Is there any option to always ignore any errors and continue boot?

Our office just switched from CentOs to Fedora and I'm trying to get everything set up. Everything is working so farbut im having a problem with my mounted cifs drives. They mount ok, I made directories in /mnt where the drives are readable and accessible. I'm only missing the shortcuts to the mounted drives in nautilus and on the desktop. I've checked the gconf editor and the volumes should be visible.Is there an extra option i have to add in the fstab line to get the shortcuts or something like that?

To avoid having to input a password for the keyring each time I connect to the net via wireless, I enabled the 'Available to all users' option in Network Manager. Now, my question is this. Are the 'users' it refers to just those created on this machine? Would a drive-by be able to use my network without entering the password?

I'd setup my new notebook letting auto-crypt swap and temp - temp for /tmp and /var/tmp - using /etc/crypttab. So I made into cryptab following:
swap /dev/sda6 /dev/urandom swap,cipher=aes-cbc-essiv:sha256
tmp /dev/sda7 /dev/urandom tmp,cipher=aes-cbc-essiv:sha256
vtmp /dev/sda9 /dev/urandom tmp,cipher=aes-cbc-essiv:sha256

I've had two hd's in my box forever. for more space and backup reasons. Well I have started running the Debian Squeeze distro since December. I've had many issues, some are still unresolved. but now I'm running into major headaches with the fstab. Specifically dealing with/wondering why UUID's are used instead of the old /dev/hd? I was a little annoyed when I tried Kubuntu to find /dev/sd? used instead of /dev/hd? but that was workable. But the UUID's are a nightmare. Here's my problem.
My main box is finally giving up the ghost. The mobo is dying. So in order to do some tests I took my hd bundle (my two hard drives with their cables) physically out of the box and temp installed them in a test box. I wanted to do some benchmark and other tests. I got all kinds of errors. I found that the system wasn't recognizing the UUID's listed in fstab. My concern is when the new mobo gets here next week I won't simply be able to plug the hd's in like I always have been and just let Linux reconfigure itself (Debian used to be good about this). I really don't want to have to clean reinstall if it's not needed.
So for this I have two questions. WHY developers decided to drop using /dev/hd? or even /dev/sd? ?
And is it possible to revert fstab's listings back to the old /dev/hd? settings. In debian fstab had lines commented out showing how each partition was listed in it's /dev/hd? status during install.
I'm getting really sick of all these archane changes in ALL aspects of linux that don't seem to have any good explaination or need.

I'm trying to connect to a new router that has WPA2-PSK encryption.In the connection window Ubuntu presents when choosing the network from the wifi menu, there are only the 3 WEP options (40/128 bits, 128 bits, and dynamic) plus LEAP. But no WPA2-PSK or any other WPA..I know for sure my router is set to WPA2-PSK and not to WEP.

I've apparently changed my fstab file and now my boot drive fails to mount. The original file is still there "fstab.BAK". How do I rename the current fstab to another name and rename the fstab.BAK to fstab? Since this is read only in the /etc directory I have not been able to make this happen from a command prompt.

I installed Maverick with auto login. One could undo this by reinstalling I suppose, but is there an easier way to get back to the standard form of login?Hopefully that will cause my default key ring to unlock correctly.

when I go to download 11.3 I am presented with the installation medium for a DVD installation with a button that says download DVD. Should there be an option to download an ISO option for a CD installation on this page along with the DVD version? Some of our older machines can only read CD's with a max size of 500+ megs.

I have an external hdd that I have added to the fstab so it will mount when I boot. But every time I add the line to fstab and reboot, it hangs during the boot process and says something about ureadahead-other status 4. here is my line in fstab..
/dev/sdc1 /NAS ext3 defaults 0 0
Is there anything wrong with that? I couldn't remember what fs I chose when I formatted it so I did "sudo parted /dev/sdc print" and it said it was ext3.

I upgraded to 10.04 and everything went fine. I had a cd drive fail(wtf?) and took it out, now apparently everything is messed up as far as what is what (sda/b/c/d etc). I've got 2 hard drives, the OS drive was sdb2, with sdb3 /home and sdb1 an ntfs parition. sda1 is /media/disk. sdc0 was the cd drive.
On the next boot up, it was unhappy that something was wrong with the /home partition.(wtf is that, there is no /home "partition", it's /dev/sdb3!), so I was like.. ok just need to go into fstab and re-arrange things. I open up fstab and, most everything is commented out... so I guess 10.04 no longer uses fstab? What does it use now?
Here's my fstab:
Code:
I commented the last two so that the system would boot. Now it wants home on sda3 and media/disk on sdb1, which is fine, but when I change those in the commented section, obviously nothing happens. I would go through and make the file legible, if I knew that Ubuntu still even uses it.

I've been having a lot of problems solving my HDD mounting problems and renaming. It finally worked, but I had to delete everything from fstab. As crazy as it sounds, it worked, when I turn my computer on, they automatically mount. They are all working fine. I will attach screen shots too. As you can see my fstab is blank, I was just wondering, is this a problem? Or is it totally normal?
