Fedora :: Upgrading - System Not Allowing Users Login

Jan 30, 2011

I upgraded my Fedora Core distribution from 12 to 14. Everything worked fine, except for SQUID which refused to upgrade. I then went to rescue and installed SQUID using yum and then restarted the upgrade. It did finally upgrade the system and then asked for a reboot. Well, when I selected the new kernel option in the GRUB options, since I also have Winduhs, it gave a kernel panic. I tried booting into the older kernel and it worked. Now I see the users that are there in the system in the Graphical GUI login greeter screen. But none of the users get authenticated. I used the rescue option and removed graphical login and changed boot level to 3. I also enabled the root user. In the rescue mode, if I do a startx, everything works fine.

I logged off rebooted the system. When I login, I see the version is shown as Fedora Core 14, but the kernel was still the older one with Core 12. I again went to rescue and checked out GRUB and saw that it had no initrd for the new kernel. I created a initrd image with the mkinitrd command and then added it to grub. I again rebooted. This time it shows the correct kernel, but still the system does not allow any of the users to login. All the Logins fail. I have tried going to rescue and going to the system using 'chroot /mnt/sysimage' and doing a startx for Graphical. Everything works, but only with the Rescue mode in the DVD. The normal boot/login sequence does not work.

Incidentally when I do a 'yum distro-sync', I get something like this :

---> Package dialog.i686 0:1.1-9.20080819.fc12 set to be downgraded
---> Package dialog.i686 0:1.1-11.20100428.fc14 set to be erased
---> Package diffstat.i686 0:1.51-1.fc12 set to be downgraded
---> Package diffstat.i686 0:1.51-2.fc14 set to be erased
---> Package diffutils.i686 0:2.8.1-25.fc12 set to be downgraded
---> Package diffutils.i686 0:2.8.1-29.fc14 set to be erased

It still seems to believe its a Fedora Core 12 system. Another information is that when I leave rescue mode and do a normal boot without installation media, it starts doing some SELinux relabelling and reboots. Any pointers on how I can get the system working. I am able to work with the rescue mode way, with any user, as it does not ask for any password. I can even do startx and work on the GUI. All my data is also there. I just am unable to get the user authenticated using normal boot/login. I have tried using passwd -d username, but it gives an error :
passwd: libuser initialization error: could not open configuration file `/tmp/libuser.ElY0r9': No such file or directory
In fact, I am now in rescue mode only when I am writing and sending this.

My GRUB file is :
default=4
timeout=25
splashimage=(hd0,9)/boot/grub/splash.xpm.gz

Ubuntu Installation :: Allowing Normal Users To Upgrade The System?

Sep 11, 2010

Here's what I want to do: install ubuntu on a laptop and then create a normal user so that the user could install the normal upgrades without using the root account (or getting root privileges via sudo).

I know that this can be done by adding the user to the admin group, but this has (at least) two bad side effects:

1. The user can use sudo to gain root access. (And then do everything: install or remove programs...)

2. The update-manager doesn't seem to appear in the panel. (In stead it opens in the background.)

I could easily make a script that downloads and installs the upgrades automaticly, but I'd like to give the user a chance to choose when to do all this. So that it's not done for example when the user is using slow mobile connection.

Fedora Security :: Admin Users Without GDM Login?

Jul 26, 2010

I need to create a number of internal Linux users for admin purposes. I do not want these users to appear on the initial console login page just after Fedora boots up, as users who can attempt to log in, and I do not want to allow these users to log in directly. I merely want these users to be accessed via su, just like the root user.

Fedora Installation :: Domain Users Logged Out On Login Using Winbind - Samba

Nov 12, 2010

Have recently setup Samba on a fresh install of Fedora 14 so that I can use it as a workstation in a Windows 2003 (win2k3) domain.

The install of Samba seems to have worked as I can connect to the Domain using ADS and kerberos. selinux and firewall have been disabled until I have it working 100%

The problem lies when i try to login to Gnome or TTY. It begins to create the home directory for the domain user logging in but after a certain process Fedora logs the user out of the system.

Have looked through several log files (/var/log/messages, log.winbindd, log.winbindd-dc-connect) but am unable to debug it any further.

Have posted the config files below which shows the Fedora machine is successfully connected to the domain as it lists its groups, users and validates logon credentials - it just won't logon!

Where i can go about debugging. Also if you need additional configs.

Software :: Allowing User To Change Their System Account Password From Intranet?

Jan 10, 2011

I have configured httpd web server to allow each of the system users to have their own web page (using UserDir directive).At the same time I have configured ftp server to allow the users to upload their html files to the web server.With above set up my users need not have any knowledge of linux; they can work from any windows PC on the network.There is no problem in the above.However, now I need to allow my users to change their passwords. The point here to note is that the users should be able to do this even from windows PC on the network. One of the way is to configure a telnet server (or sshd). But I find that the windows PC does not have telnet client.The other idea is that I should put a php script on the server which would take user name and password from the web page and then change the password. I don't know how can the system account password be changed through script - I will have to check this out.

General :: SSH Login - For Additional Users After Password-less Login Setup

Feb 10, 2010

I've set up password-less login for user1 on a Ubuntu machine to login automatically into a Fedora box using the publickey authentication method. Everything is working smoothly. Now, there is a user2 on Fedora but he does not have an account on Ubuntu.

I tried to login as user2 from Ubuntu to but got the following error :

Code:

Predictably neither scp or sftp work either. I have several questions as a result.

1.Is the SSH server rejecting user2 login because I am inadvertently using user1 keys (as I am logged in as user1) ?

2. Do I need to have a user2 account on Ubuntu and public/private key authentication setup with Fedora for user2 to be able to login ?

3. Is there a method I can use to password login as user2 from Ubuntu to Fedora (even though there is no user2 account on Ubuntu) AND still keep password-less login for user1 or do I have to have password-less login for both ?

At present the only way to access the user2 account from Ubuntu is to SSH using the user1 account and then su to user2.

Fedora Servers :: Postfix With System Users

Oct 28, 2009

Alright I have read through and tried many different tutorials but a VAST majority of them are with virtual users. This is my own personal email server so virtual users is unneccessary when I can just use the users personal mailbox.

My postfix main.cf there are 2 things I am unsure of. 1) For system users which local_recipiant_maps do i use? 2) What should mynetworks be?As I have been testing it out through telnet I can send mail but it doesnt get to my test email (a gmail account) and when i try to send an email locally it seems that everything works fine but the mail doesnt get there, and the error i am getting is that it cant find the user.

Fedora :: Switch Between Users Cause System Freeze Up

I just get upgraded from F10 to F12. I am having problem with switching between users. The system would freeze up and the mouse would move unresponsively, could not restart system with Ctrl-Alt Del. When it freeze up, it doesn't give error anyway on next start.I suspect the problem is doing with Web browser, If one user using browser and switch to other user without logoff, it will freeze up when other using login.It seem working on following contion.

1. It seems ok when all users quit using browser,and it doesn't matter how many times you switch between users.

2. delete all other users and operate as only one user

Red Hat / Fedora :: Creating Web Page For Users With Restricted Shell To Change System Pw?

Feb 3, 2011

I have a box that's used as an SFTP server. All users have restricted shell so they can only use SFTP to send and receive files. But it makes it hard to have them change their passwords. I thought that if we had a web page set up where the user could enter their username, old password, new password and confirmed new password, that this would be the easiest solution.

Fedora :: Allowing A Service To Interact With Desktop?

May 27, 2010

I'm using the Java Service Wrapper to create a service in Linux. This Java Application has no main GUI, but if certain error message occur then it displays a warning box allowing the user to know. If I log into root and install the application everything works fine. But, if I log into a none root user graphically and then do a su - to get to root the service will not start. This is the command I'm using inside the service (/etc/init.d/rc.d/backup) to start the application

Code:
export DISPLAY=:0.0
/home/pulse/backups/bin/backup start -Djava.awt.headless=true

If I take out the "export DISPLAY=:0.0" the service will start fine, but when an error occurs the warning box doesn't pop up.
