Ubuntu Installation :: Restore Users & Passwords?
May 4, 2011
I upgraded from 10.10 to 11.04 (32 bit) with a clean install as the "upgrade" option in update manager failed. I'm setting up the system again and want to restore the backup I took prior to upgrading, however due to the upgrade I don't want to just re install everything. The following have been backed up
/etc
/home
/usr/local
/var
Now there are various things that are different such as firefox 3.x has become firefox 4 Open office is gone, long live LibreOffice, my proprietary Nvidia drivers don't seem to be trusted yet, all the repositories will be different etc. I will re install all the applications fresh from the software centre, but I would like to restore all the users and passwords and their home directories,
So I don't I want to restore /etc or /usr/local en masse. I guess /var is not worth restoring either /home gets me their files but how do I restore the users and passwords? (there are about 8 registered users some of whom have different privileges) and the user ID need to be the same as they all access a NAS through nfs)

I am trying to set up Ubuntu like I had on my windows PC. I have my account, my wifes account and my kids account. I want passwords set for both myself and my wife but I don't want the kids to be required to have a password to log in. When setting up Ubuntu, it looks like it was all or none. I have dabbled with Linux off and on for years and am sure there is a way to set this up but I have no idea how.

I have done some searches and none of them tell me how to recover or where/what the file name is for the Mozilla passwords. I was able to recover the bookmarks. orrupted my system doing the 9.4 to 9.10 upgrade and I am trying to rebuild the user one piece at a time.I also need to know how can i recover my mail from Thunderbird. Basically I have set up a new user and am trying to move stuff over from the old user one piece at at time until I can figure out how to fix the old user.

Was:
Code:
password requisite pam_cracklib.so try_first_pass retry=3
password sufficient pam_unix.so md5 shadow nullok try_first_pass use_authtok
password required pam_deny.so
Become:

I'm configuring a CentOS 5.4 workstation. I have been able to apply most of the security that is required. I have met all but one logging requirement. How do you get the count of old passwords associated with users? I don't need to see their passwords just how many times they have changed them. I have set remember to 24 in the /etc/pam.d/system-auth file. I don't know where the file is that contains this information.

Sitting at the console, I log in with any user name and NO PASSWORD IS REQUESTED. I get logged in automatically without entering the user's password.
I did:
passwd joeuser
To change his password and still he goes right in without being asked for a password!
Possibly related- 10 days ago, my smtp server was breached as a spam relay. The username they cracked was deleted. I added fail2ban for postfix. The logs show no further intrusion.

On other editions of ubuntu server I had no problem saving multiple users and passwords with htdigest but now it seems it is only possible to save one user and password.
Code:
sudo htdigest -c /etc/apache2/passwords directory user
When I add a second username and password for the same directory it overwrites the first.

I have an old server running CentOS 5. The encription method used was the default MD5 for the shadow file. I would like to migrate the server to Debian Squeeze which uses SHA512. I have already copied the passwd, group and shadow file with the user accounts information but the Debian machine doesn't let the users login. I have already looked in the pam files to make it accept the MD5 encryption without any luck. how can i migrate the users without resetting their passwords?

Is there a way to use kerberos (or baring that a trusted CA) to allow users to ssh across machines in an environment isntead of having to manage the hash keys per user/server? I'm using kerberos+ldap to log folks in and get their settings but I'd like to take it a step further. I've been reading a lot but still can't quite get it all to come together.
Do I need to create a SPN for each host to do this? Sorry if I am asking a dumb question, I am returning to the *nix fold after a decade+ in the Microsoft world, be gentle with me.

I am using squid + dansguardian for web and content filtering. And it is working fine. I am forcing users to use proxy through browser configuration. Now I am planning to add another layer to controlling access using ncsa_auth program. I know it is not the most secured but I am fine with it. Plain passwords are fine with me.
I will be giving users some default passwords but I want some program for allowing users to change the passwords for the respective users if they want. Is there any perl script or something web based for the purpose that anyone is using or know of?

Im trying to set up a Proxy server on my CentOS server and I have been looking at Squid, however I wondered if there is a proxy server that will support having authenticated users and passwords in a MySQL database?I wanted to do this so I have good control over who is connected through my proxy.

I'm planning to centralize users and passwords and also create controls for user access to some equipment, for example, Linux Servers, Switches, routers and firewalls. In case of failure of the link between the ACS and AD or equipment to the ACS, this device would use local username and password.
At the moment, my AD structure is a Microsoft, Cisco ACS servers and Linux Standalone. I wish that both linuxs servers and network equipment were authorized by Cisco ACS on the accounts that are in Microsoft AD.
The configuration of the Cisco ACS to use the AD is done and no problems, the network equipment is OK too, but am having difficulties configuring the server for this solution.

I am looking for ideas for getting windows users into an ldap server. I am currently running a Linux server for my department and need to create an LDAP server which mirrors the username/password information for all of us as they are stored in the windows server here. I have the openldap server up and running on Ubuntu 8.04 and it works great; I now need to find some way to import user info into this from windows. I've seen discussions of using ldifde.exe to export the AD users into an ldif file. Is this the simplest way to go about it?
Our Linux server is currently providing us with much needed services using apache, and apache is authenticating using LDAP to our windows server (Using our windows username / password is required functionality). This windows server has some problem which causes it to delay for inordinate amounts of time between authentication requests and responses. The situation is such that this problem will not be addressed by IT staff. However, I have control over the Linux server so I am looking to just mirror the windows server on an LDAP server of my own. I could get away with updating the passwords in the Linux server.

I wonder if it is possible to have two passwords for one user account in 9.10. I have a long login password (5 words about 45 characters with spaces caps). I would like to set a shorter password for Authentication, sudo, etc. While retaining the original for logging in.In short:Have long password to login to computer.Have short password for everything after login.

Don't worry, I know - that title probably makes this question seem way more complicated than it actually is. Here's the situation: I have a server running SLES10 with a samba share set up on it. I created a username in Samba and Linux for myself, can access the share, permissions are fine, yadda yadda. Now I want to give about 100 more people access to it.
I have active directory running which users log into and I'd like them to be able to use their active directory passwords to authenticate to the share, rather than have me create 100 individual Samba/Linux accounts. In the future the AD server will be changing over to server 2008 but I'll cross that bridge when I get there. It would be equally effective if I could pull AD passwords from AD and "auto-create" the associated Linux/Samba users. Any ideas or could someone point in the right direction?

this is just weird. Did a fresh install from the alternate CD, including deleting original Win XP partition. Installation went just fine. Building this for my wife, so when asked for user name and password, entered those for her. As required, enteressword, then re-entered for verification. When setup completed, I tried to login, but absolutely could not. System recognizes the keyboard, responds to enter key, enters dots in the PW box as I'm typing but only returns Authentication Failed.
Thinking I must have mistyped the PW both times, I reinstalled. This time, I created my user name and password; the one my hand muscles know so I don't even have to think about it. Get to the end, reboot and, I can't log in!Does anybody have any idea what's going on here? I'd truly love to find out; my wife is getting restless

My Mythweb is asking for authentication but none username/password will work. It just prompts for authentication over and over again. I've found few configurations regarding authentication:
in /etc/apache2/httpd.conf I have following lines:
<Directory "/var/www/mythweb">
Options Indexes FollowSymLinks
AuthType Basic
AuthName "MythTV"
AuthUserFile /etc/apache2/httpd-passwords
require user user1 user2
[Code]...
none of the username/paswd pairs in Authuserfile are working? Can there be yet another file / configuraton somewhere? How do I know which one apache is using right now?

I downloaded a driver for my printer today and I opened it in the terminal. Then a window popped up saying "This opporation requires root (administrative) privileges. Please enter the administrative password below:" I typed in the same password that I use when authorizing the installation of programs from the Ubuntu Software Center and I tried it multiple times. Each time, it rejects the password. I even tried downloading something else from the software center, just to make sure the password was correct, but the system had no problem with the password when downloading from the software center. So, is my software center password different from my administrator password?

I installed Ubuntu Lucid Lynx a while ago. but then upgraded it to 10.10
I don't have the CD with me right now and i need to fix some mistakes of mine (being a n00b to ubuntu) urgently i.e. i can't wait for morning. Is there anyway i can rollback to the time when my ubuntu installation was in mint condition?
One more thing. Let me tell you my mistake. Almost a month ago i installed Apache2 on my Laptop (for LAMP). and now i have to install Apache Tomcat for JSP development. but the problem is that the files made by Apache2 and the PHP5 installation i made are not removed with

So now the apache2 files are superseding the Apache Tomcat. hence i cannot distuinguish between apache2 or apache tomcat when i goto:
Code:
So if anyone has a way of ridding my laptop of this disease without complete overhaul, please post your replies here.
Until then, I will have to defect back to Windows.

I just installed Win7 (I need it for work -.-") and, of couse, it installed its boot loader and I can't boot F13 any longer. The question is, how do I restore GRUB from a F13 live installation media without destroying Win7?
I remeber trying something like that a couple of years before when I had the same issue:
Unfortunatelly, that doesn't work and at the next boot I am stuck with Windows again how to restore grub from a F13 live CD?

I have installed Kubuntu on a usb stick. I installed version 9.04 from a disk that came with linux magazine. After installation I can only boot pc if the usb stick is plugged into pc before I turn it on. I then gat a menu with 5 options. The first is Kubuntu and the last is Windows XP. If I try to boot my pc without the usb stick plugged in I get a GRUB error message.
I think this is the GRUB menu which means that it must have amended the Master Boot Record. If I try to boot my pc without the usb stick plugged in I get a GRUB error message. This is generally a minor inconvenience and a great security measure. My worry is that I am notorious for losing usb sticks. If I lose this one I wont be able to boot pc. Is there a way to remove GRUB and restore the MBR?
