I ran a test where I login a test user several times using the wrong password to see that he gets locked out after several attempts. Now that I got the test user locked out, how do I unlock the test user? I tried passwd -u <test user>, but it says passwd: Error (password not set?).
View 4 RepliesI made the mistake of using the command 'adduser' on an already existing user. I was incrementing a name and mis-typed. Now the account refuses to recognize the users password. The user can get in.
I tried resetting the password as administrator (passwd 'user'), but when the user tries, the new password isn't recognized.
I tried expiring the account password (passwd -e user). The user gets prompted for a new password, but the new password still doesn't get recognized.
I unlock the root usr accout, but how can i log it on?
View 3 Replies View Relatedi use ubuntu 10.04, is there a way to set two passwords for 1 user account
View 2 Replies View RelatedI started up my computer and suddenly, I saw that there was a new user account. I didn't create it and no one else uses my computer (let alone has access to user account creations). It was called dtc. It didn't seem to have any privileges and the only file in its home folder was called Examples. Should I worry that I might have some kind of malware? I deleted the user and the folder (and it came back after a while). It's main group is dtcgrp. The User ID is 1004.

View 8 Replies View RelatedI am a new Linux user and have a question about the administrative authentication. When I am logged in as a user and I need to do something that requires root privileges the little password window comes up and I enter the root password. My question is how long are the root privileges granted for?I noticed that a few minutes after finishing checking out the firewall configuration tool and closing the window that I was still able to re-enter the fire wall tool and other administrative tools. How do I log out of the root privileges without logging out and then back into my account?
View 2 Replies View RelatedI've written an article on my site which lays out steps for installing Wine and running it under its own, separate user account, so that Windows applications cannot access personal files (particularly those in your home directory).[URL}..i'm hoping that there are people on this forum who know Ubuntu inside-out, as I'd like to know how effective the described method is at trapping Windows applications so that they cannot read or write personal files or directories.
The way I understand it, once the process is running under user account wine, it's stuck with the access privileges of user wine. But are there ways in which a rogue application could break out of this prison and gain access to whatever it wishes? I'm guessing that such behaviour would mean someone customising Windows software to recognise Linux, and that such a thing is very unlikely, but I'm still interested to hear what gurus of the Ubuntu internals think of this method.

I want to save time and trigger various software that always should start up on boot, while leaving the computer unattended during startup (extra important and practical for remote control boots), by enforcing a 'screen lock' so that no-one can see what happens behind the login screen without entering the login credentials.

View 2 Replies View RelatedI want to jail Skype into its own process and not the one I login with. That way, if a hacker breaks in, it's limited to this process and only the limited functionality that that user account has. The thing is this -- thousands of Linux guys run Skype, but Skype is hardly ever updated or have security patches, and we run it all the time. It seems like an easy avenue for an exploit. As well, my iptables firew all blocks input connections that I have not established, but Skype is an established connection. How do I create a Bash script that launches Skype under a separate user account?

View 3 Replies View RelatedDeviating from Ubuntu standard, for compatibility with another system in our network (an intradisk NAS with restricted admin features) I have to stick with user IDs below 1000 (namely 501, 502, ...)
In the Ubuntu logon screen, the related users are not shown - and thus cannot be selected for unlocking a session that was locked due to inactivity.
Do you think there is a way of accessing different user data from another account which I have set up.
Ie. user 1 = account has messed up
user 2 = account works fine
access user account 1 home directory from user 2 work space?
Apache is run as www as is all the files/folders. People are uploading via FTP, scp, so the problem is if I chmod so everyone can read, then rsync as a user it works until new files are added which then my ; if rsync fails with a permission denied. Now I can add a chmod in the script so everyone can read, but since www can already read, I figured I would just change my script to use www. I added the ssh key to his authorized_keys file, but when I try to just ssh in I see this in the secure file;
server sshd[29539]: User www not allowed because account is locked
sshd[29539]: Failed none for invalid user www from ip port 54983 ssh2
Now I read a few places already saying I need to add a password to the account, etc. but before I jump and try all I read, 1st major one, will this now break apache? Will this affect any startup things, etc. and .... will that unlock that user for ssh in or is there another preferred method?
I think this counts as a security question. I didn't know where else to place this.It's really preventing me from doing some things, such as setting up the Empathy IM program for chatting and whatnot, and this default keyring really haulting any progress I can make on that front. It also pops up when I'm just booting up the laptop. My brother set the password and then forgot, so he tried all of these passwords and it would never work. It always pops back up several moments later and reiterates its question. It goes away when I click on 'Deny', but now I can't follow that same route when trying to set Empathy IM Client up. I would like to either do away with this password requirement, or just change it to something I can easily remember

When lauching gdmsetup I can't unlock it to change settings. nothing happens when clicking on "lock" button
the same problem in Ubuntu Software Center 2.0.7. nothing happens when I pull "Install"

there are no authorization window in admin-shares too
It started when I have changed the type of ubuntu login - I have changed from gdmsetup settings from "password" to automatic authorization.
I checked the the PolicyKit Agent. It seems to working (and autostarting) with such command:
/usr/lib/policykit-1-gnome/polkit-gnome-authentication-agent-1
So I was testing to see what would happen if I tried to open a root shell in recovery mode, WITHOUT having first activated the root-user account (I only installed the system two days ago). I used my ordinary password and was expecting to see something like "Invalid password" or some such message. To my surprise, I got a root prompt. Thinking that this may just be how it works with recovery mode, I tried logging out of my X session and logging back in as root, thinking (or at least hoping) that it wouldn't work. But it did.
