Ubuntu Security :: When Try To Edit Password Via System>Administration>Users And Groups, It Doesn't Work?
Jan 2, 2010
I recently was able to network 2 computers at home and I wanted to make my password more secure. When I try to edit my password via System>Administration>Users and Groups, it doesn't workI am able to edit my user settings. When I change my password I enter my old one and it accepts my new one. Problem is when I try to install programs, login and do other things it only accepts my old password. How can I change my password?
After installing VirtualBox, add yourself to the Vboxusers group in System -> Administration -> Users and Groups.Then re-boot your computer!Otherwise you will spend hours (like me) wondering why your USB devices are not available in your guest VM.I just did a complete install on a new, larger hard drive and had forgotten this simple fact. Doh!
So i have a fresh install of the server edition of Karmic, i'm running the Xfce desktop. When I attempt to manage users and groups through the GUI, I am prompted for what I think is the root password, the reason I say this is because the account I am currently logged in has sudo privileges and it does not accept that password at all, but I read that by default the root account is 'locked,' (to be honest it was so long ago since I last installed Ubuntu I completely forgot if it is or isn't, my current desktop installation has su access) is it asking for the root password? why doesn't my current user account password work if the root account is 'locked'? I can perform all other administrative tasks with sudo no problem.
the funny thing is, I have the exact same setup in a virtual machine, the same problem happens, except for some strange reason after changing the password on the only account (besides root), the password required to administer users and groups stayed the same after the change. (at the time of installation I just put both the user and root password the same and now that it is setup), i'm now ready to change the passwords. except now I read that the root account is locked by default, but this strange problem occurs.
I have a remote directory shared over NFS called tech with perms set as 0750 and owner set to root:tech. I have 2 groups: tech, and techAdmin. tech can read and execute within tech/. techAdmin can read, write, execute. I have 4 users: user1, user2, user3, user4. user1 and user2 is a member of techAdmin, user3 and user4 are members of tech. simple so far...but wait here's the problem. If user1 creates a file inside tech, user2 cant read or modify it because user1 owns it. Here's a few sites that reference this problem:
I did a fresh install on this computer, ubuntu 10.10 server then put desktop on top of it.
I can run sudo -i, enter password, gain root access, but when i click system -> administration and it asks for my password, it always says my password is wrong.
I ran update manager, and my password worked fine there.
When i click system administration and run a task, the password screen looks different
Little more digging shows, it only occures on screens that use the login type of,
Enter the administrative password:
It doesn't even give me options for what user to use. And I am using the account created on install.
I have a Samba File Server that can authenticate users in my Windows AD to log into the server. Anyways, I have a good amount of Windows Admins on staff but our org wants to cut budget so our first "slash" as it were is cutting down the actual Windows based File Servers.So my question is, now that I have this test server up and authenticating for logins using Windbind....is there a way I can get system-config-samba to "see" winbind users and groups so that file servers can still be "point and click" for my Windows Admins?
what happened to the Security tab that used to be located in System/Administration/Log in Window I'm trying to figure out how to get a Live USB to boot to my user name and password.
have recently encountered an issue in fedora 14 whereby upon entering the root password the users and groups and authentication utilities do not run. (system/administration/users and groups) They used to run fine.
I have installed Rubrica 2.0-1.1 via the Synaptic Package Manager. I am using Ubuntu 9.10.
For some reason the groups do not seem to work at all. I add a group and some weird characters show up in the groups window. When I assign a group to a person it saves the info in the xml file but the groups window is still empty and doesn't show any groups?
I need to be able to capture a users password when they login. I am well aware of the security issues with this and I'm ok with this.
We run a call center and I am working on migrating from windows to Kubuntu for the callers. It's policy that all callers must report their password to me, so I already know of everyone's password. There has to be some variable/script that I can "hack" to get the password they typed in to the login screen.
What I'm trying to do is that when a user logs in in for the first time, their profile is automatically created and set up. Setting up network drives, email, pidgin (which the password is stored in plain text anyway, so forget about security on that one), web apps, etc.
Trying to find information on How to capture a users password and all have been responded with the usual lecture on why you shouldn't do this. So I've heard it all before and I know of the risks. Like I said, I already have the callers password on file. If I could capture it, I wouldn't have to manually setup each profile every time we get a new caller, which is often since turnover is quite high in call centers.
How to allow users to change their password in chrooted ssh as long as the modifications in the shadow file in the chrooted environment will not be applied on the system itself ?
I use the following method for preventing the users from changing their passwords , is there any other method other than this ?ls -l /usr/bin/passwd-rwsr-xr-x 1 root root 37140 2010-01-26 12:09 /usr/bin/passwdso we need to remove the suid for that command as follows :- chmod u-s /usr/bin/passwdnow normal users won't be able to change their own passwords - and only the root user will be able to do it for them.
I want the users to access servers via ssh public key only. By default they don't know their initial password and do need to change that when performing administrative tasks.For changing their passwords without knowing the old they need to switch to root for this special case.The only case it seems I don't have control is that users can not only change their password but also the password of other peoples. Does someone sees a solution (without apparmor/selinux and special /usr/bin/passwd.sh) to restrict users to only change their password?I miss the feature of using environment variables in sudoers file.
I've set up a user account for friends & colleagues that does NOT require a login password. Unfortunately, in this OS some things don't work unless you login -- sudo Must regular users have AND use Root's password?
For some reason, right click on gnome menu in the panel and clicking "edit menus" doesn't work (nothing happens).Does anyone know a command in terminal that should bring the dialog up, so I can see if any errors take place
Today I have installed Linux SUSE 11.2 . At installation, I was asked for user-name and password. I edit this correctly.
At the end of the installation, the system reboots until the mask 'user name' and 'password' will be displayed. When I edit my user-name and the password the system said, that the login is not correct.
First, I think, I have forgetten my password an do a new installation of Linus SUSE 11.2 . Whatever, the same problem ist still there.
I don't know if this is Just my Machine, or not. But here is it:
Ubuntu 10.01 Acer Aspire 7740
When the computer is locked. I can smiply go to switch users. when the list of users logins are shown all i have to do is click on my user name and it allows me into my account without typing in a password. I can lock the computer manually or wait for it to time out it doesn't matter. the switch users method allows me to bypass the password protection.
First: When I try to edit my brightness it doesn't work at all. I can turn the LED on/off but when I do up down it brings up the status bar and nothing changes. Asus K60IJ T4400 is my laptop.
The other 'problem' is the MP3 codec? How do I install this? I'm trying to use my Mp3 files in Rhythm box but can't find out how. =[Why does it have to be different ;(
when i would mount a drive (internal, external, ntfs) in 9.10 it would ask for the root password. now 10.04 doesn't do that. how can i go back to that scenario?
I am logged in with the account i created with ubuntu back in 10.4 but i cant do anything with the users and groups management tool any idea's what might be wrong? It also doesnt ask to escalate provilages when i run it which i suspect is part of the issue.
I have cross posted as it is not really a wireless network problem (wireless networking works fine) but a wireless security problem (WEP and WPA security kill wireless networking).I am not total sure which forums it should be in.From original post in networking and wireless forum:I am having a heap of issues with wireless and hopefully the following will help someone out there in guru land help me fix this problem.It seems to be more then a simple computer to wireless security problem. This is long, get a cuppa and a cumfy seat and yes this did take me the better part of 1/2 a day to complete all this testing
I volunteer my various machines and time to try and fault find the issue on all machines to help the developers to fix this problem on mine and I can document everything. Hopefully this will help someone fix wireless security on Linux once and for all.
I'm running 10.10 64-bit and have configured it for root graphical login for administration of the system. When I log in as root, I can run all menu items in System -> Administration with the exception of Users and Groups. When I try running this, the application starts, but I only get an animated spinning disk that doesn't stop, can't modify the users properties and I can't close the application unless I go to System -> Administration -> System Monitor -> Processes tab , highlight users-admin and click End Process.
how one professionaly would solve the security and administration for the multiple webadmins, but firstly I give some general information.I spent 2 days searching and there are alot of good guides but I dont see my specific questions answered, not so I can understand them atleast.I have Ubuntu 10.10 64bit server edition installed.I am educating myself and am new to linux but use vmware and have installed Gentoo multiple times and a copy of Ubuntu server. This server is going to be setup on the 64-bit 10.10 Ubuntu virtual machine.
I run apache on a non standard port(82).I just installed unity to play around with it and while I was playing with it I installed prixfixe through software center to edit the menus.While prixfixe was installing my computer was acting very slow which was odd, but not completely unusual.During this time I ran ps aux which showed that my apache server was taking up most of the processing power.I was about to stop my web server,but I waited just in case the web server was updating a few things (I run ampache).
My computer finished installing the software and then I ran some command with sudo (I can't remember what the command was), but it threw back some message saying "setid blabla". I restarted my computer and when I got to my gdm my normal user account did not show up. There were no accounts and the restart/shutdown buttons didn't work.Now I'm running on a livecd and checking out my apache access logs, apache error logs,and kernel logs,but nothing looks out of place..
Imported users and groups (UIDs 500 and above) from Redhad to Ubuntu 9.10 by appending users to the passwd, shadow and group files. Users and groups appear to work, but they do not show in the Users/Groups GUI. Is that because they do not start at a UID 1000 and up? What are my options to make them visable?
I upgraded from 8.04LTS to 10.04LTS desktop. I can do sudo as root at the terminal, but I can't pass authentication trying to add a user (System->Administration->Users and Groups).
Here is what I got: An error occurred while checking for authorizations: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. You may report this as a bug.
I recently tried installing a new version of VirtualBox PUEL version, after uninstalling an earlier version. But the major issue I have now is that I can no longer modify my User Settings. Clicking on the "Autnenticate" icon gets me a failure notice: "System policy prevents modifying the system configuration", with details reading "Action: org.freedesktop.systemtoolsbackends.set". Hovering over this link says to click on the link to edit the file, but nothing happens. Searching the file system tells me this file does not exist. Prior to this episode with VirtualBox, I had no trouble modifying Users and Groups. I was able to remove a group from the command line, but the cannot get the GUI authorization to work. I have searched the forums and bugs for similar problems, and, although there appear to be a number of similar issues, no where can I find any clear information on how this system is supposed to work, or what I need to do to correct the problem.
