Debian :: Add Users With A Standard Password?
Feb 7, 2010
I have to add my students as a user to a class-server to have them work on some TCP/IP-related questions. The server is Debian Lenny.
It would be easy if I could make some kind of script to add them, even with a standard password like 'abc123'. I want to show them the way FTP uses clear-text passwords as opposed to SFTP. Or the differences between telnet and ssh.
I know something about scripting with bash, but how can I add the same standard password to each user, without having to type it for everyone?

At the RHEL prompt, I entered the standard user's username/password combo. Linux displays a message box stating:"Your account has expired; please contact your system administrator."Next, I entered "root" in the username field and entered the root password (which expired also--keep in mind that passwords are set to expire after x days). Linux displays a message box stating:"You are required to change your password immediately (password aged)."When prompted to "Enter current UNIX password", I entered the new password (was that the right thing to do?); Linux displays a message box stating:"The change of the authentication token failed. Please try again later or contact the system administrator."I rebooted the system and got into command line mode; somehow I logged in as "root" (don't know exactly how, but needed to change the password there). At the "#" prompt, I type "passwd root"; Linux displays the message "Changing password for user root", followed by the message "passwd: Authentication information cannot be recovered.

Is it possible to switch users in Debian without entering a password, as in Ubuntu Maverick? I already tried adding a nopasswdlogin group but it did not work, even though the "don't ask for password on login" entry in the login manager is no longer greyed out. Replacing gdm3 with gdm also did not work.

I need do a small interfaz, it works under bash. I read the user name and password from the terminal then i need validate this data.
My principal dude is:
how look in the /etc/passwd file a user and passwd?
The problem is the password is encrypted and i need compare with the data I read.
Only I can use BASH because it is school homework.

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.

I need to create a script that returns a list of the users who have never changed their password from /etc/shadow.
As I know on linux there is a command "chage" used for find last password change. Any idea about solaris command?

Just wonder is it possible to install non .deb package through the standard procedure of make config etc in Debian, or better not even attempt it.I need to use several engineering, mathematics packages, Matlab, Maple and Ansys,I have been told to use Fedora, but I would prefer to use Debian, as all my computers run on Debian and its stability etc is well known, not to mention the nice people in the forum, Bugs, Evil etc, well known icons.

I'm trying to enable a non standad vertical refresh rate of my crt in squeeze/gnome under the radeon driver, which does work under lenny and fglrx out of the box without any additional manual configuration. I already tried adding the VertRefresh option to xorg.conf under the Monitor Section, but that didn't worked out so far. One strange thing is that if i look into the Xorg log file i can see a line which sais as if the driver can see the possible refresh rates, but still in gnome i cant set those refresh rates to be active
# /var/log/Xorg.0.log|less
(II) RADEON(0): Ranges: V min: 50 V max: 160 Hz, H min: 30 H max: 85 kHz, PixClock max 180 MHz
These are probably only the rates which my crt can handle, but still im unable to set 1024x768x100Hz because the max i get is 85Hz for that resolution.

Whenever I want to look at an image on the command line I use Kview, but what I want to use is the standard one you get when you click on an image file in windows mode. For me it's called visionneur d'image cos I'm using linux at my university in France.

During the installer specifically in 'tasksel', I'm given a few options. I generally de-select every possible option but what exactly is under the package group name 'Standard System'?ScreenshotObviously when I de-select 'Standard System', basically my installation of 'netinst' is almost immediately completed and I'm asked to reboot. How can I see or find out what exactly am I omitting from the system?

I'm a newbie running Ubuntu 9.10. I have two users (wife and me), and each user's screensaver is set to lock so that on wakeup, we get to choose which user's desktop to go to. However, Ubuntu requires a password, so this is pretty tedious.I'd like to switch users without entering any password. I know about this trick that works for the boot login, but it doesn't deal with multiple users.Is it possible to set empty passwords for users in Ubuntu, or skip the password in other ways?(I'm expecting real Linux users to suggest that passwordless users must not get any rights and there be an admin user with a strong password.

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/passwd
so we need to remove the suid for that command as follows :- chmod u-s /usr/bin/passwd now 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 am using Mandriva 2010.2 KDE. When I try to change my password, using the Welcome>About Me>Change Password, I am asked to type in my current password, after I press OK, the dialogue box just seems to hang, nothing happens, the computer does not freeze, just the password dialogue box kind of stops responding.

My company has policy that user accounts expire once a month and they also get locked out if they re-try login more than 3 times (pam_tally). It gets very annoying every time they come and ask to get password changed.How do I let users change their own password? Also let the system email them every day for two weeks before password expiration and until they change their password?

How can I prevent users from changing their own password? I was surprisingly unsuccessfull in finding a solution for this on google. Lots of stuff about hardening ssh access or dealing with password aging using "chage" but nowhere could I find an answer for my question.

A dutch site explains that the standard flash player in synaptic, Gnash and SWF, are so called "wrong flash players".
Translated into English:
Look whether the "bad packets" swfdec and gnash may already be installed. These may interact with Adobe Flash Player disturbing.

I am wondering how websites like banks are able to determine if you have previously used a certain computer to access the website, even if your router's IP address may have changed and your system's cookies have been cleared. I have users that need to access our HTTP intranet from outside locations. Those locations will have dynamic IP addresses most of the time, so I can't just "allow from [ip]" in my Apache proxy configuration. Originally we considered a VPN, but determined that a VPN will be overkill to access just an internal website, since we do not want external users to have permission to the rest of the network, only the website.I currently have it working over HTTPS with basic authentication against an internal LDAP server, but I want a little more security for such an important website.
crappy diagram:
[user]-->(internet via https)-->[apache gateway]-->(intranet)-->[http server]
