General :: Difference Between Sudo And Root User?
Feb 8, 2010Can a sudo user do everything what a root user can do? I read sometimes expert say "You should run it as root rather than sudo user".

General :: Sudo For Www User To Run Root Shell Script Via Browser?
Sep 7, 2010I need sudo for www (apache) user to run a shell script('ip.sh' contains iptables rules) from cgi-bin directory via browser using a per script. I edit sudoers( www ALL=(ALL) NOPASSWD: ALL ),but when run the bellow command that's with err:
# sudo -u www sh /srv/www/cgi-bin/ip.sh
iptables v1.4.4: can't initialize iptables table `filter': Permission denied (you must be root) Perhaps iptables or your kernel needs to be upgraded. And:
# ls -al ip.sh
-rwxr-xr-x 1 root root 243 Sep 7 14:18 ip.sh
I edit sudoers so
'www ALL=(ALL) NOPASSWD: /srv/www/cgi-bin/ip.sh,/usr/sbin/iptables' too. but it doesn't work too. how can I execute this script via browser ?
General :: What's The Difference Between Sudo Su - And Sudo -i
Jun 19, 2011It is my understanding that they do the same: they ask for my password (if I am allowed in /etc/sudoers), and give me a login shell as root.
Is there any difference between them?
sudo su -
sudo -i
Also, what's the difference between
sudo su
sudo -s
I think that they both ask for my password, and give me a shell with my old environment variables.

View 2 Replies View RelatedFedora :: Sudo Running As Root Instead Of Specified User?
Jan 25, 2010I have a weird question about the sudoers file. Currently, I am running "Red Hat Enterprise Linux ES release 4 (Nahant Update 8)".
I edited the sudoers file (via visudo) and added the following:
User_Alias RPTS2 = vtmtest
RPTS2 xxxxx = (jboss) /oracle/app/oracle/apps/rptsd/deploy-jboss/deploy_rpts_jboss.sh
The user (vtmtest) issues the following command
sudo /oracle/app/oracle/apps/rptsd/deploy-jboss/deploy_rpts_jboss.sh
and gets this message:
user vtmtest is not allowed to execute '/oracle/app/oracle/apps/rptsd/deploy-jboss/deploy_rpts_jboss.sh' as root on xxxxx
When I look at the log, I see the following:
Jan 25 14:17:57 xxxxx sudo: vtmtest : command not allowed ; TTY=pts/12 ; PWD=/export/home/vtmtest ; USER=root ; COMMAND=/oracle/app/oracle/apps/rptsd/deploy-jboss/deploy_rpts_jboss.sh
1. Why does sudo try to run as the root user, when I have specified in the command to run as jboss?
2. Do I need to specify anything else so that this command can run as the "jboss" user and not "root"?
Fedora :: User Uses Root Password With Sudo
Sep 20, 2010I want to use root password instead of adding my user to the list of sudoers,In Arch wiki ander Root password:Users can configure sudo to ask for the root password instead of the user password by adding "rootpw" to the Defaults line in /etc/sudoers: but that did not work for me. it asks for root password.Why do I want to do that:
1. I want to do that, I like sudo more than su -c 'some_command'.
2. sudo enables bash completion, su -c does not.
3. I don't want to add my user to sudoers list.
I found many users Suggesting alternatives and lowering the important of my need for this, when I asked this question in anther please.
Ubuntu :: Get Root User Access Without Using Sudo?
Apr 23, 2010It's been a few years since I last installed Ubuntu. I searched the forums and can't seem to find the answer. I want to be able to do a "su root" and have root access. I know Ubuntu wants you to do the sudo command, and I know you can really mess things up being root. I know I got this to work before. What do I need to do?
View 3 Replies View RelatedSecurity :: Sudo Non-user/non-root Password?
Feb 19, 2010Stumped on this one. I'm trying to set up limited sudo authority on a desktop with some sensitive user data, and as an extra precaution I wanted to configure sudo to use a password other than the user's or the root's. I'm not sure how to do this. From the manual, we have a few options, such as "runaspw" or "targetpw", but none seem quite what I'm looking for.For instance, "runaspw" could be used if I created a user for nothing other than sudo(ing) purposes, but it requires you set "runas_default", which means that said user would have to have authority to execute said commands in the first place. This is workable, but seems like a lot of extra configuration for each specific command that I want to run, as well as creating some issues with simply commands such as "shutdown" or "reboot". Also, "targetpw" can be used in conjunction with a sudo(ing)-only user if I set an alias, but, again, this isn't quite what I am looking for.
Ultimately, what I am really concerned about in this situation are keystroke loggers, so I would prefer to avoid repeated entering the user or root password when performing administrative tasks. Also, I would prefer not having to create a sudo(ing)-only user as mentioned above to prevent a comprimised password resulting in an attacker being able to log into my system.
Ubuntu :: Can't Sudo From Desktop User After Adding Root
Feb 22, 2011I recently re-installed my U10.04 and this time around, I added a root user and brought the permission levels of my default user to "Desktop User" as well as elevate the root permissions as explained elsewhere in these forums. Everything went fine until I wanted to "sudo" something from the Desktop User account terminal. I use Skype a lot and preferred to use the repos to get it loaded. Into synaptic where it asked me for the password. I entered the password and I was rejected. Ok, maybe I typed it in wrong. Tried again. The third time I checked in an editor to make sure I wasn't in all-caps. Third time OUT!
Switched user to root and there were no problems. Enabled the partner repos, installed Skype, as well as all the other stuff I use to run my home office. I have missed something, I know I have - perhaps a setting somewhere in the user permissions. I don't want to have to switch user every time I have to make changes to the system. Alternatively, if it's better practise to just leave my system as it is for security purposes I'm not running a server, but I'd like to have my system as secure as reasonably possible without elevating my problem to "paranoid security" level.......

Ubuntu :: Cannot Use 'sudo' Command Either With Root Or User Passwords
Apr 19, 2010I was wondering if someone had a logical reason and therefore complete, hopefully that makes total sense, for why when I install Ubuntu I cannot use the 'sudo' command either with root or user passwords. Even if I try to edit the permissions for sudoers, I still recieve an error message that says access is denied and so as the root user on my pc I don't understand why I can't put my name in the sudoers file or use the sudo command with the correct password.

I then logged in as root (su) and was able to navigate to the file and make changes as root. Am I missing something? How would I edit the sudoers file such that this password would work? Or is there another way to log in to the sudo group to make these changes? How do I set sudo passwords?

View 5 Replies View RelatedGeneral :: Make Sudo Ask For The Root Password?
Jul 9, 2010When I run sudo as a normal unprivileged user, it asks for my password, not the root password. That's often convenient, but it reduces the amount of information someone would have to have in order to run commands as root. So how can I make sudo ask for the root password instead of the invoking user's password? I know it'd be done with a line in /etc/sudoers, but I can never seem to properly parse the BNF grammar in the man page to figure out exactly what to write.
View 4 Replies View RelatedGeneral :: Execute Root Command Without Sudo?
Jan 24, 2010On my ubuntu I have a command pm-suspend, which puts the computer to sleep. It has to be run with sudo. Since it is inconvenient to be forced to type the password every time I want my computer to sleep, I thought maybe there's a way around it. Naively I thought that if I'd create a script as root, that invokes pm-suspend, and then let anyone execute that script, I could run that script as my own user and then that script would be considered run by root and hence be allowed to run pm-suspend. Obviously that didn't work. The root-check procedure in pm-suspend still found out that the original executor was someone different from root.
Still I think something similar (although slightly more elaborate) should work.I'm thinking about the process that allows the user to mount hard drives for example. Normally root is required, but it is somehow bypassed by the gnome utility mounting.

Mar 9, 2011Debugging some of my scripts after upgrading from Debian Lenny to Ubuntu 10.04. In so doing, I tripped over this "problem," the solution to which may give me a clue to others.
On a bash shell command line I created a file thusly:
sudo touch zero_file
and it lists as expected with default permissions 0644:
-rw-r--r-- 1 root root 0 2011-03-09 11:18 zero_file
But then this command fails
sudo echo abcdef >>zero_file
-bash: zero_file: Permission denied
I can place the command (minus the "sudo") in a script & run it under the auspices of sudo & it works. Am I missing something re the stdin redirection when using sudo?

General :: Changing File Permissions Works As Root But Not As Sudo
Nov 22, 2010I have a really strange problem. I have a few files in a large directory that I want to make readable by everyone. So I try this:
sudo find readme* -not -perm -o+r -exec chmod +r {} ;
and get this:
sudo: unable to execute /usr/bin/find: Success
I don't know why it says Success, because the permissions were not changed. I verified by typing this:
find readme* -not -perm -o+r -exec ls -l {} ;
and get something like
-rw------- 1 root root 536871076 Nov 22 14:06 readme_20101122200429
-rw------- 1 root root 536871892 Nov 22 14:08 readme_20101122200642
-rw------- 1 root root 293458128 Nov 22 14:10 readme_20101122200859
as a last resort, I tried:
sudo chmod +r *
and got:
sudo: unable to execute /bin/chmod: Success
and again Success really means fail. So, I gave up and logged in as root and tried:
find readme* -not -perm -o+r -exec chmod +r {} ;
This time it worked. Why?
EDIT: /etc/sudoers looks like:
## Allow root to run any commands anywhere
root ALL=(ALL) ALL
##Me
user1 ALL=(ALL) ALL
