Ubuntu :: Adjust Volumes On A Per-app Basis?
Aug 16, 2010I know many apps have their own independent volume controls, but not all do. Is there any way to control this in a similar manner as Windows 7?

Ubuntu Servers :: SSH Chroot On A Per-User-Basis?
Mar 23, 2010I'm attempting to give a few buddies encrypted storage space through sftp using truecrypt.I have it worked out to the point where the truecrypt volume is automatically mounted when the user logs on, and dismounted when they log off.I would like to restrict each person to their individual home folders. This way, I can control exactly how much space each user is able to use (through the size of the truecrypt volume), while maintaining security through the network due to using SFTP.
I've been looking around, and the only thing I can see is restricting a large group of users to a single directory, this won't work, I need each person to be locked down to their personal home directory.My end goal is to have these volumes "mountable" in Windows through the use of Windows network drives (on a wide network, not through samba on local), or by using expandrive or a similar program. how I can lock these users to their respective home folders?
Ubuntu :: Access To Applications On A Per User Basis?
May 23, 2010I'm wondering if it's possible to control what applications are available to certain users on a per user basis.
My motivation:
I have separate logins for audio production and general admin. Under Applications > Sound & Video I have tonnes of audio apps, but as I never use these under my general admin account, there's little reason to list all of them.
how is the applications menu configured? I'm wondering because I'd like to create some custom sections.
Ubuntu :: Change Umask On Per User / Group Basis?
Mar 25, 2011I've decided to move this question into a new thread since i haven't received an answer for 3 days. This question was originaly posted here: [URL]... I've already searched in google, however i wasn't able to find an answer that solves my problem... How can i change the umask on a per user basis so that each user can have its own umask to fit his needs? For example: I have four accounts on my system ex.
admin1 : admin,
admin2 : admin,
manager : stuff,
user : user,
-So now I want everything from the admin group to be by default set to 002 (so that every user that is in the admins group can have a full share (-rwx rwx r--) of everything that is created by the admins).
-Then the similar to the above managers shoud have 022 umask.
-And each of the regular users should have 002 or 022 or 077 it is up to the users choice.
I hope that i have provided enough info thorough the example.

Jan 26, 2011I currently use two laptops: a macbook which dual boots OSX and Ubuntu 10.10 and a Dell Latitude which dual boots Vista and Fedora 14 64bit. I would like to know if it is possible to backup the Hard drive as a whole rather than on a per OS basis. If this is possible a linux program for doing such would be the preferred method as it is common to both machines.
I am open to anything that effectively and reliably backs up both machines respective disks in such a manner which allows for practical restoration. This does not have to be done from one OS though this is my preference.

Jul 11, 2011Is there a way in Linux to give a specific application more/less priority for network bandwidth? Something like how nice does for CPU priority.
Context: I'm currently on a very low bandwidth connection (3G dongle). While I'm performing a quite large upgrade using aptitude, it becomes virtually impossible to browse the web since the upgrade download is hogging my Internet connection.
So what I would like to do is somehow decrease the network bandwidth priority of the aptitude process (and all its children) so that it won't use too much bandwidth while another process is using it.

Slackware :: Setting Timezone On A Per User Basis For Xorg?
May 23, 2011Slackware: 13.0
After having some problems with iptables not picking up automatically (without restart) the transition from winter time to summer time, and on advice from the iptables/netfilter mailing list, I've decided recently to go down the Unix way and set my hardware clock time to UTC/GMT instead of local time. I am, however, having some difficulty reconfiguring my entire machine to cope with this change.
1. I've used /usr/sbin/timeconfig - which took care of system wide timezone. After that, if I opened a terminal, du "su root" - and then check the date - it looks good. Doesn't affect though the logged in (non-root) user. Running "date" in bash window for logged (non-root) user returns wrong time (UTC) instead of local time.
2. I've added an export statement in ~/.bashrc, to set the timezone for the user account I use. That fixes the time for the logged in user, but only in the terminal. The time in fluxbox/X is still the UTC time.
Where is XOrg taking it's timezone for the logged in user? Do I amend/add to XOrg.conf? At the moment there is nothing about time zone in Xorg.conf (only contains few tweaked settings I've added to it - as I believe most of the rest is autoconfigured). I've searched - but couldn't find how Slackware configures timezones for individual users - aside from the timeconfig utility used during setup.

Dec 9, 2009I have an odd problem - that I'm having difficulty tracking down the cause!
Since upgrading F12 I have had varying levels of success booting in. Let me explain.
1. Boot
2. Plymouth graphic progresses
3. Freezes at GDM/login screen - Mouse freezes and Keyboard lights flash
4. Hard Reset with pushed in power button
5. Repeat with different kernel - usually the same result (the only exception appears to be 2.6.31.5-127.fc12.i686 kernel - this appears to have a better boot success than the other kernels listed)
In particular the .PAE kernels do not boot AT ALL ( this includes the 6-145 and 6-162 kernels). However the .PAE kernels did work on F11!
ABRT does seem to capture the following kerneloops (url very frequently (yes I do return them to kerneloops)
BUT on reviewing the /var/log/messages file they don't appear to coincide with these boot failures times!

Ubuntu :: Creating Really Big Volumes & Backups?
Oct 24, 2010First Question: I have a very big volume (20+TB). When I try formatting it as ext4, I get the error message:
mke2fs 1.41.12 (17-May-2010) mkfs.ext4: Size of device /dev/sdc1 too big to be expressed in 32 bits using a blocksize of 4096. I understand that ext4 has a limit of 1EB (about a million terabytes), but a 32-bit limitation in e2fsprogs prevents me from creating a partition > 16TB.
Until e2fsprogs is updated to use 48-bit block addressing, it appears my choices are:Break up the volume into smaller volumes < 16TB, or Use xfs or zfs (I have already created a test xfs partition, and it works fine).
Does anyone have any opinions about which option is preferable? I have never used xfs before. Is it as robust as ext4? Is it as well supported by Ubuntu? What about zfs? Is it worth downloading from the ppa?
Second Question: I now have a huge amount of data to back up. In the old days, I remember making a full backup of a "big" 10 MB hard drive by taking a stack of floppies and inserting them one at a time into my floppy drive while my backup program split the backup into 1.4 MB chunks small enough to fit on a floppy.
I now have the same problem, but at a different scale. I need to back up 20+TB onto a stack of external 2TB drives. Is there any software package that can fragment a backup in this way?

Ubuntu :: How To Auto-mount Volumes/Partitions
Feb 21, 2010I have 9.10 and notice that when I look in Places none of my volumes/partitions are mounted - if I click on them I have to enter my user password to authenticate to gain access. My problem is that (with some help) I have set up rsync so it runs when I shut down my PC and backs up my Home folder from a partition on sda to a partition on sdb - this is great but sometimes it works and sometimes it doesn't.
I have done some tests and discovered that if I use my PC and never manually mount my backup sdb partition the rsync does not work (I also have GAdmin-rysnc so I can run manually backup but this also will not run if I do no mount the sdb volume). However, if I do mount the sdb backup partition and close down/restart then the backup works. What I need is my sdb backup partition to be automatically mounted every time I switch on - can this be done? I'm sure I had this working in 9.04 (auto mounting) but 9.10 seems not to like it.

Ubuntu Installation :: Trying To Install - Volumes Won't Mount?
Apr 21, 2011I got a new computer today, a Compaq Presario CQ56, with Windows 7 preinstalled, and I want to dualboot with Ubuntu, but I'm having some problems. I'll explain what I've done so far, in case I did something wrong.
When I popped in my 10.10 Live CD, I was surprised to see there was not "install alongside existing operating system", which I thought I remembered from the last time I installed Ubuntu, but I chose manual partitioning and continued. I'd never done this before, so I quickly learned I had to first create a (couple) partition(s).
After freeing up a large amount of space and rebooting twice as recommended, I booted off the Live CD and opened GParted, intending to create a Ubuntu system partition, one for swap, and one for my home folder. When I right-clicked on my unallocated space, I got the error message "It is not possible to create more than 4 primary partitions". After a little googling, I found I had to eliminate one of my primary partitions and create a new extended partition, which I could then partition further. Noticing I had a partition that didn't seem important, HP_TOOLS, I googled and found this.
When I inserted my flash drive, it didn't automount. When I tried to mount by right-clicking and clicking "Mount", nothing happened. I also cannot mount the HP_TOOLS partition, nor any other. They don't mount when I click on them in the Places menu, and they don't mount when I right-click and choose Mount.
My main question is "Help! How do I install Ubuntu?", but I think if I can create these partitions, which requires mounting the drives (I think), I can figure the rest out.
A screenshot of my GParted window is attached, if that helps. (I couldn't see how to insert it without a URL)

Jan 3, 2010I'm just wondering - what is the best way to set up your encrypted volumes with dm_crypt and LUKS?
My understanding was that aes-lrw ws better than aes-cbc - and then I stumble upon [url] which says that LRW has some problems, and XTS is better? I dont know enough about encryption theory to be able to say anything, so i'm hoping some folks more enlightened will be able to say something here.
I was previously using aes-lrw-benbi to set up a volume. If xts is truly better - should i be using '-c aes-xts-benbi' then?
