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.
I am on ubuntu server and its joined to an W3k Domain thru winbind/samba. However everything works fine and Windows and Local users can login to the machine without any problem. However when I wanted to create a local user X and change his password I couldn'tIt created the local user X but I could not change the password. Here are the outputs:
I have no fracking clue what my password is and I want to create multiple user accounts. I have no idea whether or not I need to re-install the OS or what..nor can I even begin to imagine how to do so without a CD drive..I should also note I didn't start her up myself.
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 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.
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.

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 been asked by my professor to add the list of users to a linux server (not sure of the OS type I think he said debian) but anyway. He gave me this script to add users.
Code: #!/bin/bash # Script to add a user to Linux system if [ $(id -u) -eq 0 ]; then read -p "Enter username : " username read -s -p "Enter password : " password egrep "^$username" /etc/passwd >/dev/null if [ $? -eq 0 ]; then echo "$username exists!" exit 1 else pass=$(perl -e 'print crypt($ARGV[0], "password")' $password) useradd -m -p $pass $username [ $? -eq 0 ] && echo "User has been added to system!" || echo "Failed to add a user!" fi else echo "Only root may add a user to the system" exit 2 fi
I need to see if I can get this script to read a file that list the usernames and their passwords using the pipe command (or some similar command) so I can just do it in one batch. I've done some searching but there are so many vairiations of the code that I've confused myself. Also, I'm not too familiar with linux, it's been a few years since I've used it but in the prior script, I need to add the users to an existing group named "forensics". Which line would I change/add in order to do this?
I am changing the password of a truecrypt file container. This takes around 1 minute. Why?
time truecrypt --text --change /tmp/user1.tc --keyfiles= --new-keyfiles= --password=known --new-password=known --random-source=/dev/null"
If I use strace I see that it basically does not do anything: it simply reads lots of random data from /dev/urandom (even if i specified /dev/null as random source) and finally changes the password:
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.
regarding the file permissions of /etc/passwd in fact it has permissions like rw-r--r--so it says others have only read only permissions but my questions is if others has read only permissions on /etc/passwd file.how they are able to change their password i.e others are able to change their passwords then how it is possible.
I have bits and pieces but I'm wondering if anyone could post a step by step way to add a user using vipw? It seems handy to know. And am I correct in saying that the user added with vipw could then be added to a group using vigr?
I am running an updated Lenny. Just discovered that as user I am able to add new users via gui: System > Administration > Users and Groups. I was under the impression adding new users was restricted to root. Is this is a bug, and if so who do I report this to?
Basically if you go through System > Administration > Users and Groups then I do not get prompted for a password, I cannot see the root account, nor can I add/modify other accounts.
I understand that Ubuntu has now moved away from allowing the root account desktop access which is ok by me even though it's very much in line with something Apple would do. (odd that this comes right after Ubuntu went all apple style with the default theme too.) However, I would like to add other accounts to the machine, for my wife and anyone else i choose for example. Anyways, pushing the "add" button does nothing. Thankfully the "help" button did work which allowed me to do the following workaround.
I managed to get around this by working through the command prompt, open terminal:
user> sudo -i type in your password root> users-admin
This allows the addition of accounts, also seems it allows the root account to be enabled though I haven't bothered to test it. The one thing I'll say is that it runs VERY SLOW!
I want to add users from the command line, I know I can use the adduser for individual users, but if you have 50 or more there must be another way. I'd rather not use the GUI.
i'm working on a small servermanagement app in php to manage the ubuntu server. Someone told me I have to use the shell_exec() command in php to execute the commandlines in ubuntu.
I did a ping test wich works... PHP Code:
[code]....
But I can't seem to add any users. When I list my user using "users" command in ubuntu, I only see my loginname. How do I add users using php?
I have recently installed CentOS on my server and I am trying to install a Teamspeak server as well as a web server using ISPConfig. But, for installing a Teamspeak server I wanted to create the user account "teamspeak" to run it so my files under root are not accessible for security reasons. I was wondering if there was a way of creating the user teamspeak with a disabled login, I know in Ubuntu to do this you do: adduser --disabled-login teamspeak
I have server 9.04 and joined thru winbind to Windows Domain and subversion installed.Windows AD users can use their own credentials to join and everything is working fine.However the group svn which is used to access the repos in /etc/groups has some users.However I would like to add the domain users group to the svn group but the domain users contains Space. And /etc/groups does not happend to read the space any ideas on how to add "domain users" to the svn group in /etc/groups
I was just trying to add new ssh users for tonight session and really messed up badly. I first installed package ibsh (iron-bars shell). I didn't know how to use it so I just went to a new user account and added ibsh at the end of his .profile. (I wrote
Code: sudo gedit /home/username/.profile which I suspect is the problem, I should have written Code: gksu gedit /home/username/.profile ??)
Well graphical logging became impossible in my own account until I did the following in my own account:
Code: chmod 777 .profile chmod 777 .ICEauthority
But desktop is still empty. I have restarted the system. I cannot use Firefox (it works without output for 10 sec and then dies). Chromium says something like "Problems due to not being able to update profile" but works. (I cannot see any files on desktop. But if I do places > desktop I can see them.) All the mentioned files had -------- for permissions so I did:
Code: chmod 777 ~/Desktop/*
How to get my system back to normal. I think I got botched up permissions. If I create new user accounts, I get several error messages in these accounts.
I currently have an LDAP database on my Suse 10.2 server for managing authentication and controlling emails for my Cyrus email server. I use this setup to provide email functionality to my web and email hosting clients, as well as DNS functionality, and it uses the default LDAP database that was setup when OpenLDAP was initially configured. Email support is working wonderfully, I might add. I also tested and verified the use of an email lookup directory in two different email clients (Outlook and Evolution) so that I can tell one of my clients how to lookup the email address of users who are setup in the LDAP server, and it works beautifully.
However, I'd also like to be able to allow my clients to build a shared contact database that can also be used in their email clients so that they can share them among all of their users. Ideally, I would need to be able to allow each client to have their own database of shared contacts, and I assume this would be done by creating a new LDAP database for each client company (i.e. group of users) that can contain the list of shared contacts for any of that client's users. When they configure their email client directory settings, they would enter the base path to their database in order to retrieve their shared contact database entries.
In my web searches, I've found plenty of CRM solutions on the web that claim to provide this type of functionality, but I believe that OpenLDAP contains everything I need to make this work without adding another layer of software to the server solution. (I subscribe to the "Keep it Simple, Stupid!" approach whenever possible.) Essentially, I need to have People entries in a client's LDAP database that are NOT email users on the system. The fields in the standard people schema are all the fields they would need - as long as I can figure out how best to add these non-user entries in the LDAP database. Are there any potential difficulties in creating additional LDAP databases expressly for this purpose?
Are there any tricks to adding contact entries into a client's LDAP database without them also being current email users on the server, so that those entries can be retrieved through an Email Client directory lookup? I will also want to provide an easy method for my client users to add new entries to their LDAP contact database, most likely through a web interface for them that could then issue LDAP commands on the server based on the input fields for the new contact. (I don't believe this is possible from within the email client itself.) Is there any reason this could not be done with the proper configuration? What should I be aware of as I setup this contact management web interface? Is there a better way for non-technical client users to manage this list of shared contacts?
I installed and configured LDAP server and client on RHEL5 successfully. Problem is that when I add more than one user on server and clients, It shows error 'invalid user'.When I run the command:-#chown -R user:users /home/user, It shows error 'invalid user'. by step for adding and modifying more users in ldap servers.
