Security :: SUDO Permission Setup On Particular Dir - Recursive
May 6, 2010
I am looking for a way to setup sudo access for a user, so that he can change permission of all files of the given dir.
eg:
By this user can change ownership of files which are on depth bellow to given dir (i.e /etc/userA-conf/), but while trying to change permission of /etc/userA-conf/../user-conf2 , getting error, user userA don;t have that permission.
Let me know what will be the right regex/pattern to achieve this.
In Solaris it's working fine, but I am trying it on Linux RHEL5.

I am using Ubuntu 10.04-alternate-amd64 for full disk encryption. After getting my updates which i get as soon as they are released. I am getting the issue temp root (sudo) password is not being revoked. After using any app that requires the use of sudo the permission for it does not get removed like it normally does.
I have tried logging out then back in, which usually removes the permission, this no longer works, also tried waiting and even after 1 hour permission still there. The only work around I have found is to use the terminal to execute the required programs then after closing terminal the temp permission is now removed like it should be. This issue has effected all of my systems and a friend of mine as well, (friend uses same distro).
To replicate issue:
1) Boot system.
2) Login.
3) Check for updates or any other app that uses root permission.
4) Logout
5) Login
6) Repeat step 3
7) App will not ask for permission it will use root permission automatically.

I have a CGI script that when called runs another script as a different user. Yet when the script does run I keep getting a permission denied in the logs and the script fails
In the sudoers file-
Defaults env_reset
www-data ALL=(charly) NOPASSWD=ALL
For the full question-
When looking at /etc/sudoers there is the defaults line that you can add things to. When doing a sudo -L so that I can see what I can put on that defaults line. Can an individual user have specific defaults? Ones that don't effect the rest of the people in /etc/sudoers?

I have mounted a iomega file system on a cetos os machine using
mount.cifs //filserver-ip/directory /home/my-home/mounted-file -o
user=username
(** mounted as root) The mounting works fine.
The problem arises when I try to create a sub-directory inside the mounted directory. All the newly created sub directories become write protected.
I am accessing this file system from R software and it needs to write/create directories in side this mounted directory.
how can newly created sub-directories will become automatically writable, so that R can create new sub-directories and write data inside those directories.

A day ago I finally got around to upgrading the PackageKit installation that had been sitting for a week and a half, so I found a new upgrade for sudo available - the one that gives the sudoreplay command, I forget which version number it is exactly. When I try to use the sudo command I get this notice in my terminal:Code:Can't open /var/db/sudo/me/1: Permission deniedI didn't get it before. What do I have to do to make it open? I'm using SELinux in enforcing mode if that helps.

How can I give www-data permission to use sudo? I used to assign permission to users to use sudo using KDE but don't know how to do it on a headless server.Basicly I have a web application running that wants to call a command that needs root privs. When it calls this command it's running as www-data. I guess it's not working as www-data is not allowed to use sudo. If it can use sudo I could for example...Code:echo "password" | sudo -S "some admin command here"I could be wrong but i'm petty sure I just need to give www-data permission to use sudo?

I am new to fedora (been using debian based distro's for the longest time). With the new release I decided to give FC13 (The kde 64 bit spin) a try. I told it to wipe my entire hdd and encrypt the partitions. The partition manager made a few LVM partitions which I assume are encrypted.
The problem I am having is that if I attempt to use an application that would normally need root access to run, I am not prompted to enter my root password. Instead, I am required to logout and log back in as root. Is there a way to make it so that FC13 will prompt me to enter in my root password so I do not need to log in and out? Or is there something Different I should have done during the install process? Also, what is the terminal equivalent of "sudo" in fedora, or is it still sudo/KDEsudo
I also have not used SE Linux before. Do I need to manually enforce the permissions for my applications and generate my own profiles for it, or is that done automatically?

I have a problem about user permission, I just destroy my user...So, I create a new one. But I can't have the permission to use "sudo" or to install program... So, I cannot do a lot of thing in my computer. The logical solution is to boot in failsafe mode and access to the root terminal, but, I don't know how to change the permission to allow me to use sudo.

If I try the sudo mv command on the file listed below I get the error listed. I am confused. It is my file & I have permissions. Somehow a slew of files on my system are now showing this way. This seems to correspond when I ran rsync from my netbook to sync it up with my desktop where I am having a problem.
Potential Source ->
sudo rsync -av --delete --rsh=ssh joe@192.168.1.4:/media/Abyss/Memories/ /home/joe/Pictures/
Type of issue ->
mv: cannot remove `100_2259.jpg': Permission denied

Every time I try to open Nautilus it requires root permission even if I don't use commands like gksudo.
I launch it from docky's bookmarks applet, requires root.
Use a command like "nautilus /home/harvey" it still requires root.
Adding the file browser launcher to docky doesn't even LAUNCH nautilus.
But launching file browser from gnome-panel works O_O.
But I never use gnome-panel, so I'd like to be able to launch it from docky and commands and stuff without root permission.

I am attempting to configure my sudoers file, and have quite a few questions.If you can answer any/all of them, I would be grateful.
-Is there a way to set it up so that root gets notified if a user tries to use a command they are not allowed to?
-If something like this already exists on my system, how do I set it up/use it/ read root's messages?
-I see a lecture=always default exists, but can I customize this lecture?
-Is there an easy way to explicitly deny a user sudo permission?
-I see there is an ALL wildcard. Is there something similar to a NONE wildcard?

How do you setup the sudo command so that it will insult the user if they enter the wrong password? I know it sounds kind of random, but I found that it was an option while looking up something else. I tried adding "Defaults insults" using visudo, and commenting out "Defaults targetpw" and "ALL ALL=(ALL) ALL", and adding my username as "blank888 ALL=(ALL) ALL" but I still can't get it to work right.

Does anybody use openshot in Slackware 13? What I made: I modified the slackbuild script for openshot of Slackbuilds.org for version 1.1.1 and then I made the package and installed it. Of course the dependencies too. But when I start Openshot, I get the following error:
OpenShot (version 1.1.1)
Error: OpenShot has not been installed in the Python path.
(Both the site-packages and /usr/share/openshot folders were checked)
Use the following command to install OpenShot:

Is there a way to delete files on the commandline that uses the KDE-Wastebin?It appears that I never ever need the KDE4 Wastebin for files that I deleted through Konqueror or Dolphin. It is only when I delete files on the konsole with rm that I wish I could undelete them. It always happens like that, mostly by being in the wrong directory or using a wildcard when I should not have. (I don't have any erroneous deleted file right now, and I do have plenty of backups, but I just wonder whether there is something better than rm to use generally on the commandline.)

A few days ago I tried to install a driver for a Brother printer (HL-5040) in terminal mode by issuing "sudo dpkg -i --force-all hl5040lpr-1.1.2-1.i386.deb" on my Ubuntu 9.10 PC.
During the process several error messages were displayed. All of them say "permission denied" to access a directory /etc/init.d/lpd. Consequently, the installation failed and Synaptic package manager does not work any more and becomes broken.
Questions: Why did I get "permission denied" as a su? How can I get around the problem so I can re-install the driver?

I'm breaking my head on this.I want to create a development environment. This means that I want to be able to create/change files myself, but php should be able to do the same. I installed a lamp-stack using tasksel. Afterwards I installed phpmyadmin. So far so good. Going to http://localhost shows "it works".
Then I created a folder /home/hwc/www and created a new apache site called hwc, disabled default and enabled hwc that points to /home/hwc/www and has the directive AllowOveride All set. But when I go to http://localhost know I get a 403 Permission denied error. I've tried several trings like changing ownership of /home/hwc/www to www-data:www-data, to hwc:www-data, to hwc:hwc, but all to no avail. Even adding www-data to group hwc and hwc to group ww-data did not help. According to other posts at least on of these solutions should have worked, but it did not. I could probably fix it by letting apache run as hwc, but that doesn't seem right.

I wanted to setup a local Apache2 server for some programming and testing. I installed and got Apache2 working with PHP, MySQL and all works fine. Now I wanted to add an additional directory to somewhere in my /home. And that's where things went wrong. I went to edit /etc/apache2/sites-available/default. This is it:
Code:
<VirtualHost *:80>
ServerAdmin webmaster@localhost
DocumentRoot /var/www
<Directory />
Options FollowSymLinks
AllowOverride None
</Directory>
<Directory /var/www/>
Options Indexes FollowSymLinks MultiViews
AllowOverride None
Order allow,deny
Code:
You don't have permission to access /po/ on this server.
So I go to the logfile; which says this:
Code:
[Sat May 08 16:43:51 2010] [error] [client 127.0.0.1] (13)Permission denied: access to /po/ denied
I tried a lot of stuff using chmod and chown, but all to no avail. I tried to change the ownership of the /home/name/web to root, and to www-data, I changed file permissions to allow executing the files.
