I have installed Ubuntu Server 10.10 in Virtual Box in order to evaluate it for a project.I have installed Gnome and can log in fine using my password. However, whenever I am prompted for my password when doing anything SUDO I am told my password is incorrect, starting Synaptic, for example
View 9 RepliesI am suddenly not prompted for my password when I run any command as sudo on a few of my Ubuntu servers.
if I run sudo -K, the session is cleared, and I am prompted again for my password, however it saves/caches it until I run sudo -k again even if I log out and back in. I want it to prompt me for my password, as it should (and did) by default, for security.
Any ideas what could be causing this?
Here's my /etc/sudoers file code...
I have installed ubuntu-desktop and can log in fine. Whenever I start Synaptic, etc and am prompted for my password I am told it is incorrect. I reinstalled ubuntu server and tried the same thing with xubuntu-desktop and I experience the same thing.
View 1 Replies View RelatedI cannot sudo nor log into a second ssh session on my Ubuntu 10.10 server edition headless setup. Entering an incorrect password works as expected but the correct password gives errors, and on the second attempt a segfault. I recently changed my password as the old one was about to expire, that was 3 days ago, I can't find evidence that I have sudo'ed or logged in a second session since, I have been logged into it via ssh throughout all of it and I am still currently logged in. What should I do to correct this problem? I'm worried that by turning it off I will lose all access. Is the only option using a live cd to change the password?

I have a server that started out at 8.04 LTS was upgraded to 8.10 and to 9.04. When I upgraded to 9.04 sudo and ssh stopped working.
Fortunately I have a root account and can login as root or su to root.
I suspect this is the result of changes I made to nsswitch.conf and pam.conf to get winbind working.
I was hoping for a fix by upgrading to 9.10, but that didn't work. I want to upgrade to 10.04 LTS, and stay there but I think need to resolve this first.
auth.log reports failed password for ssh attempts and authentication failed for sudo. I am at a loss to determine where the problem is and how to track it down.
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: IDLmg.org/CORBA/COMM_FAILURE:1.0)"
Moving past that, I changed my user password, and Ubuntu authenticated it.
How do you launch Synaptic Package Manager from the command line?
I also have the same problem. but on 9.10. have you solve the problem? It will be wonderful if you can give some hint.

Is it possible to have your login password t be different then your SUDO password. I did a search on sudo password- Almost every post has the term in it.

View 8 Replies View RelatedI have one of those ultra reliable Ubuntu servers in the corner that I never have to logon to because it never needs anything. I needed to check up on it today and my root password would not work. I am absolutely sure I did not forget my password and because I am the only Linux guy in the office I am sure some nimrod didn't get his fingers in the machine. I attempted to enter GRUB recovery mode but when I hit ESC it says something about no disk and goes into the booting process. I attempted to use a desktop version live CD, but the file structure is unreadable, I assume due to the security of the server system. Before I rebooted it the server worked fine, Apache and PHP were working away. Now the whole thing is a 50Lb boat anchor. How can I reset the password when I cannot enter GRUB menu or use a live CD?

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?

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...

View 3 Replies View RelatedI 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.
My root filesystem recently filled up. I finally established why - that my /media directory had filled up due to the USB-attached device having been unmounted for whatever reason, and SimpleBackup tried backing up without the mount in place - thereby filling up the filesystem.
I discovered that the root directory was full when the machine tried to get updates, and couldn't. So, I went into /media and tried to delete the backup directory and file(s) that were in that directory, but it tells me that permission is denied. So I try to SUDO the same command, and it tells me 3 times in a row, "Sorry, try again", followed by "sudo: 3 incorrect password attempts".
So, how to I get root privileges back again?
Code:
name@machine:/media$ sudo rm -R FreeAgent
Sorry, try again.
Sorry, try again.
Sorry, try again.

I've read through some threads here but the problem I'm having doesn't seem to be the problem others are having.

View 5 Replies View RelatedI have to enter the root password every time I want to run
Code:
sudo vpnc
and I know that there is a way to avoid entering password every time but I can't remember what it is.
when I try to do admin tasks - e.g. setting my wireless connection to "available to all users" or updating a group's settings - it asks for "password for root" rather than asking for my password so it can sudo.I was forced to enable the root password, so I could do anything on my system ( sudo su; passwd; ) but I'd rather keep my root password locked and use sudo if possible.

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.

View 10 Replies View RelatedIt appears that Lucid has done away with the gksu prompt that used to greet you when you try to mount a partition. Is there any known way of restoring this? I have a number of partitions which I would rather have protected by a password (even though I know that booting a live cd will give anyone access to any mountable partition, no questions asked). I've had a quick look in gconf and found nothing that looks like it would control this behaviour, but it's quite likely that I overlooked something.
View 9 Replies View RelatedBefore you say you shouldn't do that bla bla bla. I know why i shouldn't.
However i have a problem with running sudo commands from a non interactive command line script run using plink.
The automated script needs to use chown and give the current user ownership of some files and folders created by another user.
I can't use things like sudo -s etc as it requires that i enter a password.
I have setup public key authorization in order to login. Do i have to give the root user a password and log in as that. I would prefer not doing this but if that is the only solution i guess i'll have too.
This is a new installation.My system login password is recognized and that same passwd is recognized by the Software Centre, but not with sudo in the terminal.

I upgraded from Super Ubuntu 2008.11 to Ubuntu 10.04.1 online ( my mistake ). Now I can boot into Ubuntu 10.04 with 2 kernel options and a failsafe. However I can only boot as a user ( rejean ) and not as su or sudo. My other problem is that I don't have a gui. I would like to do a Code:sudo dpkg-reconfigure xserver-xorgbut there is no password that works.What should I do?
