General :: Safer No Password Sudo?

Nov 22, 2010

This is on my host machine. I'm the only one using it so it's fairly safe, but I have a very complex password that is hard to type over and over. I use the console for moving files around and executing arbitrary commands a LOT, and I switch terminals, so sudo remembering for the console isn't enough (AND I still have to type in my terrible password at least once!) In the past I have used the NOPASSWD trick in sudoers but I've decided to be more secure. Is there any sort of compromise besides allowing no password access to certain apps? (which can still be insecure) Something that will stop malware and remote logins from sudo rm -rf /-ing me, but in my terminals I can type happily away? Can I have this per terminal, perhaps, so just random commands won't make it through? I've tried running the terminal emulations as sudo, but that puts me as root.

Security :: Using Sudo Instead Of Root Be Safer?

Apr 5, 2011

Consider: [URL]

In security terms, would using sudo instead of root be safer? I'd actually prefer to use this if so; I like sudo an awful lot. (It's Mark Shuttleworth's fault)

General :: Sudo No Password

May 23, 2011

I have an old server running RHEL 5.5 and I normally just type sudo nothing else and I'm instantly root. I copied my sudoers file from here to a new server but it seems not to work cause I type sudo and it ask for usage. Is something else besides the sudoers file that prevents me from logging in with sudo only.

General :: Sudo With Seprate Password

Oct 7, 2010

Is there a way I can setup sudo with a seprate password other than root and the user password and yet I need it to pull the password from the passwd file. Ok here is why they are wanting to tie the sudo password into cyberark appliance that manages the passwords. So when the user needs to run a root command they would check out a password from cyberark. cyberark changes password from in the password file. So to restate myself is there a way to set sudo up to pull its own password from the password file and not the users or root.

General :: Sudo - Run All Commands With Password?

Feb 16, 2010

Having a problem with sudo. I'm down as a user who can run all commands as root provided I enter my password. The relevant line from my /etc/sudoers file :


user1 ALL=(ALL) ALL

There are several commands that I run quite frequently such as mount and fdisk but would like to avoid having to enter a password each time I use them. What would be the appropriate change to the sudoers file ?

UPDATE: I neglected to scroll down to the bottom of the /etc/sudoers file where there was the line :


%admin ALL=(ALL) ALL

and since user1 was a member of the admin group any predeeding lines were being overidden by this. Commenting out this line and adding


user1 ALL= NOPASSWD: /bin/mount, /sbin/fdisk

General :: Make Sudo Ask For The Root Password?

Jul 9, 2010

When 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.

General :: Sudo Su Runs Without Password Prompt?

May 25, 2011

So here's the problem. We've got the /etc/sudoers file set up so that users can run commands from /bin like "cat" or "mkdir" without entering a password. The problem is that the "su" command is also in /bin, so if they enter "sudo su", it gives them root access without a password. Here's the /etc/sudoers file:

Defaults targetpw
%users ALL=(ALL) ALL
root ALL=(ALL) ALL
support ALL=(ALL) NOPASSWD: /sbin/, /bin/, /opt/, /etc/init.d/, /elo/
support ALL=(ALL) NOPASSWD: /usr/bin/mysql

Is there a way I can deny /bin/su while still allowing the rest of the /bin commands?

General :: Sudo For A Single Command With No Password Entry

Apr 20, 2010

I wish to allow a user to use sudo to run a single command (service app status) to determine if my application app is running, in my sudoers file i have: user ALL= /sbin/service app status I understand that there is a parameter called timestamp_timeout that will set the timeout for the 'user', but requires at least 1 entry of the root password.

I wish to allow the user to do "sudo service app status" and not have to enter the root password ever(maybe once is ok), but still make the user enter the root password for all other root activities. Is there a way to prevent the password entry for this command only and no others?

General :: Specify Password For Sudo Command When Running Bg Process?

Jun 23, 2010

I'd like to start a background job using the sudo command and route its output to a file. This presents a problem because the prompt for the password doesn't work properly. It looks something like this when I try it:

Mac:server user$ sudo php crossdomain_server.php > data/crosscomain_output.txt &
[3] 30303
Mac:server user$ Password:
[3]+ Stopped sudo php crossdomain_server.php > data/crosscomain_output.txt
Mac:server user$

Basically I'm not properly prompted for the password and as soon as I type anything in my background job fails because it didn't receive the password. Is there any way to execute a sudo command by supplying the password on the same line as the command?

General :: Sudo Command Occasionally Asks For Root Password?

Sep 9, 2010

In Ubuntu 10.04, I logged in as user1 and when I open a new terminal and issue any command it is asking password.user@ubun-laptop:~$ sudo ifconfig[sudo] password for user: It is asking for password only for first time.From the next command onwards it is not asking.Can some one please tell me if it is possible to issue ONLY ONE COMMAND, in which even if the password request comes, it will automatically fill the password.Just like "ps -elf | grep NetworkManager". I am expecting any combination of commands in a single line, so that password is filled automatically IF PASSWORD IS ASKED. If password is not asked, the command must be executed.

Ubuntu :: Sudo And Login Password Recognized - Password Box Does Not Like

Apr 27, 2010

I needed to use Synaptic Package Manager to install an app, but the dialog box ("enter the Administrative Password") that pops up before you can use Synaptic doesn't recognize my password ("incorrect password). I tried typing it into a text editor and it's spelled right, caps lock not turned on or anything.

In Terminal, sudo recognizes it, and it is recognized when I log into Ubuntu. I'm the sole user, I have admin privileges, I've been doing admin things.

I just now did System > Administration > Users and Groups and got a dialog box saying

"Failed to contact configuration server; some possible causes are that you need to enable TCP/IP networking for ORBit, or you have stale NFS locks due to a system crash. See [URL] for information. (Details - 1: Server ping error:"

Moving past that, I changed my user password, and Ubuntu authenticated it.

How do you launch Synaptic Package Manager from the command line?

General :: CentOS / Sudo Doesn't Accept Root Password But Logging In As Root Works

Apr 9, 2010

I was trying to edit a file requiring root permissions, so I used sudo. I typed the root password and it failed. This happened three times, and the process was ended. 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?

Ubuntu :: Sudo Isn't Asking For Password?

Jul 27, 2010

I installed ubuntu minimal install with xorg, lxde, and lxdm During the manual install, I do remember it asking something about extra encryption on password or something like that which was "highly recommended" and I chose yes, which probably has nothing to do with my problem, which is: Whenever I run something in the terminal with sudo, it just opens without asking for password. What did I do wrong? How might I fix this?

General :: Why Does "sudo" Ask For The Same Password Again

Jan 29, 2010

A long time ago when I worked in a Unix shop the system administrator would use "su root", give the root password which only he knew, and then did work.On linux now you use "sudo". I tried it with the wrong password, but it makes no sense to me to ask for your user password a second time in a shell and give that person root access.

Ubuntu :: Ask For Root Password Instead Of Sudo?

Dec 16, 2010

When i install or upgrade the system I want to be asked for the root password instead of just the normal password for sudo. The reason for this is that the kids and so on uses my system and know my password. They do not know my root password though. I do not want them to install or mess up my system by pure fumbling, so is this possible to do. A simple change in who runs the updater/install features...

Ubuntu :: 10.04 Sudo Not Needing Password

May 4, 2010

I installed Ubuntu 10.04 as a vm in VMPlayer 3.0. My correct user password is required to log in. When I use the sudo command or enter an area that requires my password, the password box pops up as it should.

The problem is:
If I enter my actual password, it is not accepted.
But if I enter nothing, as in just hit enter, it works. It shouldn't.

That seems just a little backwards and I don't get it. I've re-installed the vm and still have the same problem.

Security :: Sudo To Root Without Password?

Jan 26, 2011

We have a couple of clusters that are running Oracle. If you're familiar with Oracle you know that it basically has to be installed as root. Something I detest. anyway, when we are building out the box, we change the root pw and give it to the DBA team to do their installs and configs. When they are done, we change the root pw (and do not give it to them), and configure sudo to allow them the rights needed to manage Oracle and their databases.

Now however, we have a different situation. The DBAs need access to uninstall and reinstall components and make modifications on an ongoing basis. Since we only support OS and hardware, not app, they are requesting permanent root access. I promptly told them no, and the politics ensued. Their manager went to their director, who went to my director, and suddenly an exception is given for his good golfing buddy. So here I am, forced to turn lose DBAs on my clusters with full root access/pw. I need a way to allow specific users (or perhaps a specific user group) the ability to become root WITHOUT sharing the root pw with them.
