Ubuntu Security :: Bad Login Protocols - Graphical Login For Gnome Sizes Itself To Accommodate A User's Exact Password Length

Dec 14, 2010

I'm seeing really bad user login format under a standard installation and am wondering why ubuntu does this as default. I have noticed that the graphical login for gnome sizes itself to accommodate a user's exact password length. This indicates to me that somewhere on the unencrypted part of a standard installation with user encryption contains at least some indication of the content of the password length which seems a security flaw even if not a complete hole, it majorly reduces the number of attempts a cracker would have to cycle through.

And that's assuming that *only* the length is contained. Furthermore it seems that it would be MUCH better to simply display the number of characters entered into the pw field and allowing the gui to expand itself from an fixed size as the field is filled out so the the user still receives visual feedback for entering characters. Either a simple character count display should be entered into the field or a 10 dot to new line so that one can visually quickly count the number enter by multiplying from a 10base graphical observation.

Ubuntu :: GDM Login/switch User Screen Blank - Autologin Works

Jan 5, 2011

I've run into a strange problem with GDM that I haven't managed to find a solution for yet, either by trying myself or googling, and I have run out of good ideas. I'll just infodump here about the problem and what I've tried etc;

I installed Ubuntu on a new PC a few weeks ago, setting it up with autologin for my mom and a separate user for myself, using the on/off-icon menu in the top-right corner to switch to my own user and back as needed, and logging the user out when done. This worked quite well.

However, a few days ago, this stopped working; logging out or trying to switch now leaves me with a blank black screen, without even a mouse pointer (but not off, the backlight is on).

EDIT: To clarify, this is an issue that only affects the GDM login screen, but that affects it whenever it is used, wether it is on boot (when not set to autologin), after logging out, or when trying to switch user.

At this point, I can usually use Ctrl-Alt-F1 to get a textmode login, and Ctrl-Alt-F7 to get back to the auto-logged in session (assuming I tried to switch, not logout).

I can't think of anything specific I did or installed around then that should be related in any way...

I tried disabling autologin and restarting gdm, which left me with the same black screen (which is still there after rebooting), instead of the expected login window. I managed to re-enable autologin by manually editing the /etc/gdm/custom.conf file, so that it would at least work for mom.

I've also tried to change which user is auto-logged in, thinking it might be a problem with my user account, but both users get an automatic session just fine when I restart gdm.

I thought it might be a problem with the video driver, but that's not the case - if I run zenity --info as root with DISPLAY set correctly, the dialog box appears on the screen just fine. It has no borders or titlebar (there's no windowmanager), and is apparently without keyboard focus, so since there's no visible mouse pointer I can't click the OK button... But since it appears, X is apparently up and running just fine, just has nothing to display other than a black background.

I tried purging and reinstalling gdm and gnome-session(-bin|-common), but that didn't help any.

Running ck-list-sessions after trying to switch indicates that there's a new session there, with session-type = 'LoginWindow', so it appears to think everything's fine.

Enabling debug output in the /etc/gdm/custom.conf file did get me some more debug output in the gdm logs, but it didn't really tell me anything, there weren't any obvious problems that I could see.

After some looking around, I've guessed that it's supposed to be running gdm-simple-greeter, which I assume would display a login box; trying to run it manually doesn't work though (it's missing some environment variables, and trying to add them based on the abovementioned debug output doesn't really help).

Red Hat / Fedora :: Login - Error "no Profile For The User Can Be Found And It Couldnt Create Per-user Gnome Configuration Directory"

Aug 8, 2010

I have a network set up that has been working for around a year with no problems but has now developed a login problem. The system was set up with a main server with all users on it and another PC located elsewhere that people could log onto using there personal login and password that then gained access to the account on the main server. This remote PC has now got the problem. When you try to log onto an account it comes up with the message "your session has lasted less than 10 seconds. If you have not logged out yourself this could mean there is a installation problem or that you are out of disk space."

Error message says that no profile for the user can be found and it couldnt create per-user gnome configuration directory. I can log on as root onto the remote PC as it is obviously a local account but all the account on the main server are not accessible. From the root account I can see that the connection to the server is OK and I can actually log into the accounts on the server using the failsafe session so the physical network is OK.

I never built or designed this set up and to be honest I normally work with windows so its all a bit strange to me. Both PC's run Centos 5. I have checked the messages log and there doesnt seem to be any indication of a problem. Just that it stopped connecting from the remote PC. The accounts are all active on the main server itself and have no problems being accessed.

Fedora :: F13 - Cannot Login As NIS User By Using Gnome Or GUI

Sep 24, 2010

I have a problem concerning about NIS. I have set-up a NIS client, but I am not able to login as NIS-user by using GNOME or KDE login GUI. However, I was able to login as NIS-user by using a terminal that's open from a local account or root. Also the NFS seems working as well. This problem only occur on my new FC13 pc, and I don't have this problem on my FC10 pc. Both of my FC13 and FC10 PC have the same NFS and NIS setting.

Ubuntu :: 11.04 With GNOME 3 Won't Login The User?

May 2, 2011

I was eager to try GNOME 3 in Ubuntu 11.04 (because I wasn't very satisfied with Unity, like almost everybody around) so I installed it using this guide:http://news.softpedia.com/news/How-t...4-194085.shtmlAfter rebooting the system (to finish the installation), I've got an error message while trying to login:Quote:Could not update ICEauthority file /home/<username>/.ICEauthorityI've googled for some time and found different 'solutions', however none of them seems to be working.What can be done with a system like this? I'm not able to login, how can I downgrade the system?

CentOS 5 :: Gnome-login Configuration - Restore User Profile?

Nov 20, 2009

Last night I started my computer and loaded my CentOS 5.2 partition (Windows 7 on the other partition). I was able to login to my account, but was given a gnome error that the panel buttons (i.e. weather, cpu monitor etc) could not be loaded. I then went to restart the computer (probably not the smartest thing to do) and was given some file errors upon shutdown that were related to /dev/VolGroup00/LogVol00. After restart I was taken to a shell and ran fsck manually. It seemed to find a lot of bad blocks, so I repaired the /dev/VolGroup00 system and restarted. At this point CentOS seemed to boot normally, but upon loading of the login screen I get the error: Configuration not correct The configuration file contains an invalid command line for the login dialog, so running the default command. Please fix your configuration.

I cannot even log in as root. I get the error /usr/bin/gnome-session: error while loading shared libraries: libgnome-desktop-2.so.2: cannot open shared objects file: no such file or directory. I then went to a shell and ran: sudo yum install libgnome-desktop-2.so.2, but the package was already installed and up to date, so there was nothing to do. I am therefore stuck at this login screen with pull-down menus and tabs where I can change the configuration, add/remove users etc. So, my question is this: How do I restore my user profile so I can login....and if anyone has some insight, what caused this to happen in the first place? I should also mention, this all happened after plugging the computer into a new internet connection. No clue if that's even relevant.

Fedora Networking :: Pam_mount Not Mapping Network Drives On Gnome User Login?

Nov 18, 2010

Have been configuring fedora 14 to connect to a windows domain server and have been successful so far....am now on mapping network drives when the user logs in via the gnome gui.

If there is a better method of mapping network drives on login

After reading up on PAM_MOUNT and using that for mapping drives on login I have been able to successfully map them, but it doesn't do this automatically on gnome login.

Problem is as follows: It works when i connect / login using the terminal but requires me to enter the password once (even when i logged into the user account on gnome).

How I want it to work:I would like the mapping to occur when i login via gnome so that i dont have to open a terminal once logged in to gnome to map the network drives. I would like it to login without having to type the password again as the user is already logged in

Config Files:

#--- ~/.pam_mount.conf.xml ---#
<?xml version="1.0" encoding="utf-8" ?>
<pam_mount>
<volume fstype="cifs" server="GRA.GI" path="apps" mountpoint="/mnt/GRA.GI/apps"/>
</pam_mount>

General :: Login As Other User Using Shell Doesn't Load The Profile For That User?

Dec 11, 2009

I am using the sudo command to log on locally as another user by the following command:

sudo -u theotheruser -s
or
sudo -u theotheruser sh

As I see it, this initiates a new shell with the mentioned other user.However, this doesn't load that users profile from his home directory.Is there a way to automatically read the users profile when login in with selected command? I am mostely interested in getting a working prompt when logged in.

General :: Nagios 3.2.3 - Blank White Screen After Login

Jun 6, 2011

I'm relatively new at Linux, and I am trying to get Nagios to work correctly. I'm running CentOS if that matters. I think I followed the directions here correctly, but all I get is a blank white screen after I login. The documentation page works fine, but I don't see anything on the main http://localhost/nagios page. I have looked at other solutions to this problem (adding the correct path to the open_basedir in /etc/php.ini) and that still did nothing. Any Way to decode my httpd logs... Any time I refresh, I get these four errors from /var/log/httpd/error_log:

General :: After Booting Logging Into The User A/c - Gives A Blank Screen With The Desktop Wallpaper

Jan 8, 2011

I just put on my Linux PC now and after booting logging into the user a/c, it just gives a blank screen with the desktop wallpaper - no menu's or anything, so there's pretty much nothing I can do. I know I had removed the menu and replaced it with the dock (awn dock or something).

However, I can log in as root and root works fine (so I'm doing the update at the moment).

Coming back to my question, I used to know an Ubuntu command which I put in as sudo (terminal)and it used to work like a magic command which would literally restore and repair my linux installation - I even used it when I bought a new system and transferred my linux hard drive from my previous machine to the new one and this one command actually setup and prepared my linux installation to work smoothly in my new PC - just one command after connecting my h/drive in the new PC.

General :: Blank Screen And No Login After FC12 Installation On Dell E6410

Jun 3, 2010

I am trying to put FC12 on a new Dell E6410 (laptop) with video "00:02.0 VGA compatible controller: Intel Corporation Device 0046 (rev 02)". I used the Live disk and successfully installed, but then I updated. Thereafter when I boot I get a black screen. I cannot even get to the login.

Unfortunately I really do not know where to start to try to trouble shoot. (I can get into run level 3 on the latest kernel). Also the issue seems to come about from kernel 2.6.31.5 to kernel 2.6.32.12 since the blank screen issue does not arise in the former. For now I switched the order of these kernel in GRUB so the older one boots first and this seems to work.

Although the blank screen is my most pressing issue, I am having others too (synaptic mouse, wifi, suspend, internal camera). Well, hopefully once I can run the newest kernel these issue will disappear.

General :: Red Hat 5 - Login - Asking Me For A User Name At The Terminal

Oct 28, 2010

I am using red hat 5. It is asking me for a user name at the terminal. I do not understand what it is asking of me. A user name was never established during installation of the program. it did ask for a root password during installation which i provided. At the terminal i did try typing "root" for the log in and the actual root password for the password. It gave me administrative access.

However, i don't know the correct command that will take me to the desktop. For windows i simply typed in win or exit to go to the main windows desktop. Linux is foreign to me... can anyone help? I would be greatful for the advice. I am a windows junky from way back.

General :: User Login Not Working

Aug 9, 2010

Talk about being thrown in at the deep end! I am not used to linux systems but I have inherited a linux based internet setup that I need to take care of.Two machines (both have centOS 5) are networked and one is accessing the /home directory so people can log onto their personal home folder.The log in screen on the second machine usually just requires the individual to input their username and password and it automatically accesses their folder on the other machine.At the moment it doesnt and comes back with an error saying that the session lasted less than 10 seconds. Looking at the error message it is saying that the profile was not found and couldnt create per-user gnome configuration directory.

I am able to log in to the local root user on the machine and I can see the networked drive and even access the home directory.looking thru the network setting I see that the other machine seems to be acting as a samba server?? and is connected with SFTP?Any idea how to fix this problem as I have a load of guys sharing 1 PC for internet access in the middle of the atlantic Ocean on a ship!
