Ubuntu :: Access To Applications On A Per User Basis?
May 23, 2010
I'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.

I'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?

I'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.

is it considered standard practice to change the user password on a regular basis and if so how often?

I have a 9.04 machine that is used by the family with two accounts set up. One is mine with sudoer privileges and I prefer fluxbox. The other account is for everyone else and the rest of the family prefers gnome. Is there a way to set the default DE/windowmanager for each user so that each user simply has to login and be in their preferred environment?

Slackware: 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.

Original HOWTO can be found at: [URL]... So the other day I was in IRC and someone had brought up a problem where they created a new Administrative user, but didnt have rights to use sudo. Looked into the problem a little bit to figure out what was wrong, and it turns out that when you create a new user through the user manager (in kubuntu, anyways. Havent tested in Gnome.) the user gets added to the adm group, however, a quick look at the sudoers file shows that its looking for users in the admin group to allow the use of sudo. So, to solve the problem we do the following: If youre on the new admin user (which Im assuming you are) use the following commands:
Code:
su [insert username of old account without brackets]
sudo usermod -G admin [username of new admin account without brackets]
exit
Then simply logout, and then log back in (not always necessary, but the easiest way to flush the permissions.)
Code:
su [insert username of old account without brackets]
Means were going to Switch User to the old admin account
Code:
sudo usermod -G admin [username of new admin account without brackets]
This simply adds the admin group to the secondary group list for the new user
Code:
exit
Pretty self explanatory

Ie. user 1 = account has messed up
user 2 = account works fine

Prelude: OpenSUSE 11.2 (2.6.31.8-0.1-desktop), installed Novell client 2.0 SP2 (novell-client-2.0-sp2-sle11-i586.iso).
I found that if any usual user is logged into a NDS-tree, then _local_ root has full access to user's network shares, including the user's home directory located on remote Netware-server. Is it by design or
have I missed something? Nevertheless in windows local admin has no access to network resources mounted of any other user. If you runas shell (as admin) then admin in principle can't "see" network shares which were mounted (connected) by other users - they are accessible ("visible") per session.

Take a physical user FRED. FRED is a linux user ( known by linux on his laptop ) FRED is a Samba user ( Known by samba on the samba pdc server ) When he logs locally (with username/password) on its standalone laptop (with no network), he is known as FRED:user. He access his data in /home/FRED/. When he logs through samba (with username/password) on the domain MY_DOM, he is known as MY_DOMFRED:MY_DOMdomain user. He access his data in /home/MY_DOM/FRED/. ) Is it possible that the human FRED has only one repository and have full access to its repository regardless of how it was connected. If yes, how to do it
2) If not, Is it possible that the human FRED has full access to /home/FRED/.............. and /home/MY_DOM/FRED/.

I'm developing an application in which one user must run java software that I'm compiling as another user. I wanted to give user A permission to see the bin direcory of my workspace, which is in the home directory of user B. I was wondering how can this be done? I gave the bin direcotry full read/execute premissions, but since it's in my home directory user A can't navigate to it.
I know there are a few ways I could get around the problem but they arn't very elegant. I was wondering if there is a simple method for giving a user access to a specific directory without giving access to all the parent directories. I tried symbolic link but user A still can't access it, and a hard link to a directory isn't allowed in Linux. I don't feel like making a hard link to every single file in the bin directory, and I'm not sure that would work anyways, since every recompile overwrites them.

I am trying to give access to ONE single user to start and shutdown tomcat server. The problem being, when I enter syntax: username ALL= /etc/init.d/tomcat5, /usr/local/tomcat/webapps, PASSWD:ALL This gives the user access to start and stop tomcat but also gives user access to start and stop other services within /etc/init.d - such as httpd etc... What is the proper way to give user access to start and stop service, and limiting that power to only one service....

Whenever I try to do anything that requires administrative permissions, including Synaptic, the Update Manager, or installing something on the Software Center, the "Starting Administrative Application" task comes up on the window list, but then the window does not come up and whatever action was supposed to be taken does not happen; no error messages, nothing. Also, whenever I use su or sudo in the command prompt, nothing shows up when I type my password; then when I hit Enter, it gives me an authentication error.
EDIT: It seems that the "Add/Remove Applications" program as well as the Software center do not have this problem. Synaptic and the Updates Manager, however, still do not work.

I have searched and searched for answers to this question, but I can't find what I'm searching for anywhere. At least with the search terms I'm using.So, my question is, is there a backup software for Linux that backs up not only a user's home folder, etc, but also the user's applications, and its associated data.
I am about to upgrade my mother's computer to Lucid, but I don't want to do that until I can find a backup solution that will ensure she doesn't lose any of her application data. She has a lot of apps on her netbook, so just finding out where each individual app stores its data and backing it up is kind of out of the question. Unless every app that the end-user uses (that isn't run as root, obviously) stores its data in the home folder, then it would be easier.Honestly, I use a Mac and I guess I'm just used to the simplicity of Time Machine, which certainly backs up applications, application data, user data, and even extra executables in all the /bin folders (which Macs don't typically use to store most applications). I've heard TimeVault is like Time Machine, but when I tried to use it on her computer, it wouldn't work because it wasn't compatible with the version of Ubuntu that was (and still is) on her computer.

I have installed a lot of CLI applications and it would be usefull if I had another one of these that lists and organizes ;in different ways ,what has been installed without a GUI. I tried this (rpm -qa | less) and it was lack luster and enormous. Is there a GUI or a CLI application that will list User installed CLI application and allows ways to list them , alphabetically or otherwise etc?

I'm using Kubuntu 10.04 at the moment. Every time I log in, KDE Wallet asks me to give a password so that Kopete can access my login password to login. Is there any way you can 'grant permission' to access the wallet for certain applications so that I don't have to fill in my password every time?

I am using ssh on windows XP to remotely connect to a UNIX server that provides web application development services. The server is called snapper and is also designed to run computer-intensive engineering and GIS applications. I have been able to successful access the server. However, when I try to run an application I get an error message saying:Application initialization failed: no display name and no $DISPLAY environment variable
The ANSYS Launcher could not be started The most likely reason is that your DISPLAY environment variable I either not set (i.e. issue setenv DISPLAY dev:0.0 where dev is your device name) or is set to a device that is not accepting the connection. I was hoping someone could explain to me what the DISPLAY environment variable is and how to set it.

I can't get a program (wbar) to run directly from my user account, it fails saying "Image not found -> maybe using a relative path?". But if I run su -c "wbar", it shows up and manages to load the image. I think it has something to do with ImLib2 or whatever loads the image. I checked permissions on libImlib2.so.1 and it's world-readable and executable. Can libImlib2.a be causing this problem, set to 644? What else should I be checking?

Would it be safe to say that if I build a restricted user: "Desktop" or "unprivileged" user I will be ok? From what I understand - most scripts or applications cannot install without the 'sudo' prompt and user input.

I'm currently working on a project in a secure environment with no internet access and I need to install Ettercap and Wireshark on the machines. I thought this would be a simple task of loading Wireshark onto a USB but this did not work and replied with error messages such as: ' Invalid config x86_64-unknown-linux'
what does the error message mean and do I need internet access to install the apps?
