In our cluster of RedHat4 & 5 machines, if someone locks the computer and walks away no body can use it. Is there a feature in RedHat5, Gnome, KDE etc that would allow for the option of switching users at the lock screen, so more than one person can be logged in
View 11 RepliesI have a problem with Switch User on a newly installed Ubuntu 10.04 on Asus Eee 1101ha.When I try to use Switch User, I just get to the Lock Screen of the currently logged in user, where I'm asked to enter a password.There is also "Switch User" button on the Lock Screen - the screen gets black and then gets back to the same Lock Screen. Login Screen is not displayed.

View 6 Replies View RelatedIs there a way to set Linux to automatically log in to a specific user account and at the same time lock the screen? I want to save time and trigger various software that always should start up on boot, while leaving the computer unattended during startup (extra important and practical for remote control boots), by enforcing a 'screen lock' so that no-one can see what happens behind the login screen without entering the login credentials.

I've also tried uninstalling gnome-screensaver as was mentioned in another thread when I searched, but no joy there so far.
View 9 Replies View RelatedI'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).
I must to give ssh connection to own customer. So I want to lock ssh user on own home directory. It is not necessery to reach other folders. I know that ftp user can lock on own folder but I don't know how to lock ssh user.

This seems to most commonly occur with .mp4 files, but also occurs with .avi. I have gotten this problem while playing videos in Totem Movie Player, VLC, and Banshee. My system has 4GB of Ram and Intel Dual Core T4200 processor (2.00 Ghz).

A simple integrated card, but should be enough for watching videos. Perhaps a driver upgrade is what I need.

View 2 Replies View RelatedAll servers mentioned below run OpenSuSE, either 10 or 11.I am currently working on a few scripts that are meant to be used as part of a continuous integration setup. I am trying to keep these scripts reasonably secure, and so I have made sure that all the servers run these scripts only as a specific user (user1) that has permissions to basically nothing else. The problem I am currently running into is that I need to start and stop tomcat as user1 but this user doesn't have permissions to the tomcat rectory (only tomcat has execute permissions). I have a temporary workaround in place while I work on the scripts (I have an SSH key in place that allows me to SSH from user1o tomcat without a password and execute my commands that way) but it is not very secure. I have tried adding the following line to /etc/sudoers:
Code:
tomcat localhost = NOPASSWD: /opt/tomcat/bin/startup.sh, /opt/tomcat/bin/shutdown.sh
but it doesn't work as I expected it to. I tried a few different syntaxes for that line,

I am using Ubuntu 9.10, GNOME.
It's very disturbing when making a Kiosk application, every time the lock screen and screensaver shows up, also many popup + battery or updates shows up.

USB driver bug exposed as "Linux plug&pwn" or this link.Two choices [GNOME, Fedora 14]:
1 - use the gnome-screensaver
2 - use the "switch user" function [gnome menu -> log out -> switch user]
So the question is: which one is the safer method to lock the screen, if a user leaves the pc? Is it true, that using the [2] method is safer?Why do i think this? - The gnome-screensaver is just a "process", it could be killed. But if you use the log out/switch user function, it's "something else". Using the "switch user" function, could there be a problem like with the gnome-screensaver? Could someone "kill a process" and presto...the lock is removed?Could the GDM [??] "login windows process" [e.g.: a picture of it] get killed and the "lock" gets owned?
p.s.: if the [2] method is safer, then how can i put an icon on the GNOME panel, to launch the "switch user" action by 1 click?

View 2 Replies View RelatedI'm trying to get my screen to turn off whenever I lock my screen. I know that in Power Management, there's an option to turn off the screen after a set amount of time, and I know about xset dpms force off, but the former doesn't allow me to turn off the screen from the logout menu, and the latter only turns the screen off for a short amount of time (1 minute or so. The screen just turns back on by itself).
Is there a script I can modify to change what happens when "Lock screen" from the logout menu is selected, or is there a script I can add to the panel to lock the screen and then turn the monitor off (and turning it back on when I shake the mouse or something)?

View 1 Replies View RelatedWhat happens is that I resorted to deleting my .kde directory after my kid destroyed my profile where title bar, menu, konsole get broken. After deleting, I login again thus regenerating the .kde directory. To avoid my kid from messing my desktop, I tried to lock it. It does not lock.
It just need a KDE full restart perhaps since when I login the other day, it now works.
I'm updated to Slackware current for almost a month already and have not played a lot on KDE desktop (busy programming stuff).
However, on day I tried to lock the desktop in KDE to avoid the kid from destroying my cool desktop setting, but it didn't lock. Cool, so I tried screen saver and add an option to lock the screen.
When I test screen saver, it displays. But when I wait for 1 minute(I set it that way), it doesn't fire up. Not even after 15 minutes which I think the default.
It usually work before (several months ago) using the lower version of KDE. It is just last Saturday that I noticed it.
I tried to dig the profile management but I could not find anything relevant there.
I work for a local community college, and we currently have web kiosks set up around the college. They have fairly old hardware and are currently running windows XP. However, with all the group policies and scripts required to lock them down, it can take 10+ minutes for the students to log in(we want authentication for someone to be able to use them).
Now, I have managed to get a few test computers to run fedora with openLDAP authentication and LTSP giving them a desktop with firefox. Now, the problem is that we don't want the user to be able to do anything but run firefox and, on some of them, print. I have been using gnome, gconf, and sabayon(not the distribution, the user profile tool) to attempt to lock down the desktop. However, anyone can just right click the gnome menu and add back in everything i disabled. While they wouldn't be able to do much harm, the point is that if they want to do work, we want them to go to our computer labs, instead of the kiosks. The kiosks are just for looking things up or getting on their e-mail.

View 9 Replies View RelatedI am trying to disable accounts after 5 unsuccessful login attempts. I am following the guidelines in this article:

This is on an Oracle Enterprise 5.4 box, which is essentially RHEL 5.4 Here is what my /etc/pam.d/system-auth looks like:
--------
#%PAM-1.0
# This file is auto-generated.
# User changes will be destroyed the next time authconfig is run.
[code]....
Unfortunately, the account does not seem to be locked or disabled. As root, runninng 'su test2 -c <some-command>' always sucessfully runs <some-command>, and leaves the failed attempt count at 6. /etc/shadow does not have an * or ! anywhere in the encrypted password for the 'test1' user.
What am I doing wrong? I thought that with the max attempts set to 0 in faillog, that the deny= parameter would be used. I thought I should be using su <user> -c <command> from the root account to test if the disable feature is working.
