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 just want to prevent from now on from all users maybe even root from adding other users to groups like wheel for example. I also want to know how can I prevent from all users to create new groups or add users to new one.real
is it possible to authenticate users logins by a database (postgres, mysql)?for instance: -user types username, pasword, at login screen -OS then connects to server with database and checks if the user is valid. if so, is it feasible to add a time lock function for each user? in the sql, postgres table ? for instance user sandra can only log onto the computer for 1hr at 5pm
I have to set up a box which can manage all the logins in our company and has the feature to manage every possible permission with as much comfort as possible. We are using Linux and AIX therefore my Boss is willing to switch from our Windows DC to a Linux DC. And here lies the problem, I don't really know what is needed to set the Box up to manage the Unix, Samba and LDAP accounts with one tool maybe?
I would like to know which Software exactly is needed and how to manage to get the thing to work together with a security aspect. I configured a Samba DC with LDAP, Kerberos and TLS but it looks like I overdid it because Kerberos is not able to manage the things we need in a manner that the other Admins in my Company would get things done in a short time.
Therefore I would like to get listed all the Software needed and maybe some How Tos how to get thing working, because I am losing my nerves on this matter. In the last 3 weeks I have set up several test boxes but every time something doesn't work. My biggest Problem is to get Samba and LDAP to work together with TLS or another security scenario.
I am new to CentOS, and am having a problem with authentication.The system accepts the login if the first 8 characters of the password are correct, regardless of the length of the password.My root password is 15 characters, but entering the first 8 my login is approved, which is a bit of a security concern.I think this may be something I am missing in the PAM configuration.I've experienced the behavior on SSH as well as Webmin.
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'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'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 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 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.
we are using firefox-3.0.15 from the CentOS-Repository and the adobereader plugin from the adobe-repository. We have a curious problem with adobereader-plugin in firefox.When a pdf document is displayed via the plugin, i.e. within a tab in firefox, all input fields are disabled. I cannot enter a search string or fill in fields. The cursor and page up/down keys are also disabled. But when I configure firefox to open pdf documents with the external acroreader, everything works fine.
Additional notes:* We are just migrating from SuSE. Some user profiles are working as expected without problems. Unfortunately, I was not able to figure out the important files: I traced all of firefox' file operations on the user profiles, but there are no significant differences between working and non-working profiles (I just compared filenames, not content).* the same adobe-plugin works with firefox 3.0.15 from mozilla.org* I also set up a clean i386-Centos 5.4 from original CD, SELinux disabled, updated and created standard user. I only added the adobe-repository. The same effect, no search avaible.
I'm running 64-bit 10.04, upgraded from 9.10. The problem I am experiencing is that any user accounts aside from my main account are problematic. This includes any accounts I add, as well as the GDM guest session.The specific problems that I have thus far experienced are as follows:
1. The desktop loads often improperly. In the latest instance of this the graphics on the right side top panel were randomly chopped-up, leaving parts of my clock on either side of the volume control, among other things. 2. If I make ANY customizations to the desktop at all, the desktop takes nearly a full minute to load on log-in. 3. Flash videos don't work properly on Firefox. Sometimes they only play after refreshing a page, often they will not load at all. Also, attempting to load or play a flash video will sometimes causes Gnome or Firefox to crash. 4. (And this is the one that REALLY has me stumped) Whenever I log into my main accountant after logging out of another account, the IBus control appears in my system tray.However, when I open the IBus preferences the associated check box is (and has always remained) unchecked.Not sure where to go with this one. More than anything, the IBus bug makes me unsure of where to even begin looking for the problem.
I have Ubuntu 10.04.2 (Linux 2.6.32-33-server on x86_64) with OpenLDAP 2.4.21 and Webmin1.550. I converted my ldap database from another system with the older style schema (OpenLDAP 2.3.3 with slightly older Webmin version 1.480) and no longer use slapd.conf, but the newer slapd.d format.
It all works fine except for one thing. When I add a new user, it lets me type in the additional LDAP fields:
But when I click the Create button, all the fields get jumbled together in the Title/Position box with a diamond question mark delimiting the fields:
Modifying existing users (which have the Additional fields displaying correctly) also has the same result - it moves the fields all into the one Title/Position box with the diamond shapes with question marks inside between each entry. Is it a problem with my schema files? I tried reverting to the older shema files and slapd.conf and it still did the same thing on the new system. I am really at a loss.
Here is also the output of ldapsearch for that user (host and samba ids are sanitized):
Previously added users that show the fields properly have "description:" and then the field listed for each Additional LDAP field. Also shouldn't the "title" be visible in plain human readable text here? - it looks like it encrypted it somehow - similar to a password hash. The older system works fine and the fields are all readable and in their proper locations. But the new system just doesn't work right.
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.
I've installed rubygems on ubuntu, but it has a known issue that the rubygems' bin/ directory is not in the PATH. I know about exporting the PATH variable, and adding it to .bashrc, but I'd like to configure it so that every user has it on his PATH, even if he tries to run it with sudo. Where should I export the PATH variable then?
I can't get CentOS to stop seeing my drives as a fakeraid, even though I disabled the raid settings in the bios. Therefore, I can't install. Previously, this box was running Vista 64 bit. I have an nVidia mainboard and two 500 GB sata drives. The mainboard offered raid support, so I enabled it. Windows saw the drives as a single raid0 drive and installed on it flawlessly. Never had a problem. Two days ago, I finally got off my horse and decided to get rid of windows and install CentOS. I left the raid intact, installed CentOS on the fake raid. Upon rebooting, GRUB wouldn't load. Booted up a live disk, fdisk saw the drives separately but couldn't read data from them.
Tried a second install, same problem. Wiped out the the data on the drives using gparted. Tried a third install, same problem. Did some research, found out that my raid was really a fakeraid and that a better option for my needs is a softraid. Disabled the fakeraid in the bios. Booted up the installer. It still loads the nvidia /dev/mapper driver. It still sees the drives as a fakeraid. Wiped out the drives using gparted. Booted up the installer. Still sees the drives as a single /dev/mapper/nvidia_lkjwer drive. Installed Ubuntu to see if I'm crazy, or if it's centOS. Ubuntu installed w/o a problem (on a single drive). Enabled, disabled, tweaked every freaking possible bios setting. Still sees the drives as a fakeraid.

So far, I've been able to get my Box (Centos 5.3) authenticate users through LDAP. My next plan was to automount their home directory from our NAS device.But I'm struggling getting autofs talking to the LDAP Server.My Config Files:
