Is it possible to prevent the disclaimer from being displayed as soon as one logs into a terminal? I am referring to the six standard terminals.
I searched the contents of /etc and googled without much success.
my linux system doesn't have X only console login possible. i would like to deny all user to login from any sources, local machine, remote console (putty, winscp) etc. except root.
i've found something about /etc/security/access.conf and i've put:
+ : root : ALL
- : ALL : ALL
but still users other then root are able to login (via putty for example).
New to Linux in the last year, used Debian Wheezy off and on for a time - trying to build a system up from a minimum net-install, just to learn more about it.
I have a niggling little problem - either of understanding or configuration. I started with the min install and installed X using apt-get or aptitude. Then installed JWM, which I would start from the console via startx. I really liked this setup, since it was simple and I knew what was going on. This was all on Wheezy.
After the upgrade to Jessie (via dist-upgrade), I would get messages popping up "on top of" the console login when I booted. Stuff like "b43-loading firmware …" would pop up on screen while I was typing my login/password. This was kind of disconcerting (seemed like something must be misconfigured) but didn't effect functionality at all.
Eventually I decided to try a display manager, since that would (I thought) avoid the whole console login process and thus the weird overlapping messages. I installed LightDM through aptitude and it works great, but the console login is still displayed first (briefly, maybe 3-4 seconds) before the LightDM greeter takes over the screen.
It is there just long enough to confuse the unwary, who start typing their login name only to have the screen replaced by the LightDM login screen and have to start over. Obviously this isn't a big deal (everything works fine), but since the whole point of this project was to understand, I'm very curious if this is normal behavior (videos I've seen of folks installing Debian seem to show boot messages jumping straight to the DM without showing:
Debian GNU/Linux … tty1
debian login:
or if I've neglected to configure something that would allow boot directly into LightDM or hide the text console while LightDM loads or … something.
When I try to log in the screen just flicker and I get back to the kdm login.
If I use console login it just turn black and after a while it get back to console and no protocol specified shows up together with xinit: giving up.
If I use root there is no problem and I can get into the desktop so it must be a user configuration problem or.....
I have been using my system for couple of weeks, and normally update software when the icon is displayed on top bar (gnome). Last couple of days there were updates for X, and I am not sure whether that is the cause of my problem. Once bootup, I get the login screen. When enter the password the login screen keep coming back. there is no error about any password issue, or anything. It keeps prompt me to enter the password.
I could login back the following way.
1. ctrl + alt + F1 , and login with the same username/pwd as for X
2.change to root
3.pkill gdm3
4.exit from root to user privilege
5. startx
The system starts X correctly and no login screen is displayed. I could use the system as usual.
The only thing I did custom to my system was upgrading to the latest kernel (2.6.38) using the source. This was to get support for my hardware, but that was about a month ago. I do not see anything in /var/log (X, demesg etc).
I installed 2.6.38 from backports. It boots OK, and among the start-up messages it says it has started kdm, but then it offers only a console login prompt, no GUI. I assumed (perhaps optimistically?) that newer kernels would be backward-compatible, and that any dependencies on other software would be enforced by the package mechanisms. Running amd64, Squeeze, KDE.

I have a ATI Mobility Radeon X1400 card on ThinkPad T60. Everything was working on 8.10, and I decided to install 10.04 and now it doesnt work.
I wanted to disable root logins in console, so I searched for that. I found that if I change root's bash to "/sbin/nologin" in "/etc/passwd", root user will not be able to login. So I did that. But when I wanted to use sudo command, it didn't show me root bash, but it only do the same thing as logging in as root in single user mode (shows message that this account is disabled). So, how I can disable root logins, but keep enabled sudo command for standard users?

View 3 Replies View RelatedI am using Arch Linux and want to disable console messages which are displayed when the kernel boots. I have tried the quiet and loglevel=2 options in /boot/grub/menu.1st as given below:
kernel /boot/vmlinuz26 root=/dev/disk/by-uuid/c6dbfcdc-fcd8-498e-9182-f3bddc4f05ff ro loglevel=2

Any ideas where I am going wrong?
I have my headless server, and just plugged a spare monitor into it, opened up screen, ran htop on it, so I can see the system status, but the screen keeps shutting off after so long. The only way to "wake it up", is to use a local keypress (which means I have to hook a keyboard back up to it). I have already tried 'setterm -powersave off -powerdown 0', but it didn't affect it any. Is there any way to disable this powersaving mode?
View 3 Replies View RelatedI run a custom build of linux running kernel 2.6.24 and busybox. At the moment I'm investigating a kernel panic. The problem is that after 10 minutes the screen is blanked, i.e. it is still on but has been turned black. If you press a key then the command prompt is shown once again, but if the kernel has crashed then this won't work and any info about the panic is inaccessible. So I'd like to prevent the display being blanked. I've tried booting with 'apm=off' and 'apm=off acpi=on' kernel parameters but neither had any effect.
View 5 Replies View RelatedI have a webserver that I run myself utilizing CentOS 5.3. I added a postfix server just to send outgoing mail to people who are part of my webpage. I do not do any email exchange so I can actually receive email on the server, only send (if someone can help me out with that I'm willing to listen).Basically I want to add a disclaimer to the bottom of every email that gets sent out, no matter who sends the email, stating the the email is sent from an unmonitored email account so don't reply to the email. I followed the steps listed here [URL].. even though it was for Fedora 8 it seemed to do what I needed it to do. For some reason no matter who I send email with the disclaimer does not show up. I am doing masquerading so when the email gets send it shows it comes from my domain, not localhost.localdomain because most webservers block it assuming it is spam mail.

View 2 Replies View RelatedI'm trying to debug a game with gdb. The game runs in fullscreen and causes a segmentation fault and then gives control back to gdb. However, since the game is in fullscreen, the gdb session can't be viewed. So, at this point I did CTRL-ALT-F6 which blanks the screen and gives me a console to login with. I do this and determine the PID of the game process and kill it. This should remove the x-window the game was using and leave the gdb session on my gnome-terminal. I then exit the console login, which leaves me at a console login prompt.
Now is the problem. How do I return back to my gnome-terminal gdb session, ie, how do I recover from my console login? Via email, somebody informed me that CTRL-ALT-F9 works for him, but it does not for me. In fact, I've tried CTRL-ALT-<every function key> and nothing works for me. The only thing for me to do at this point is to kill the power.
(BTW, the game must be debugged in fullscreen because the problem goes away when not in fullscreen.)
I'm running openSUSE 11.3 32-bit.
I"ve started using Ubuntu 11.04 with my Intel iMac. Today I was playing EDuke32 on Ubuntu then the game got freezed, so I tried Ctrl+Alt+F1 and it worked. I just logged in the console and typed;
sudo reboot
This actually didn't work, so;
/usr/bin/sudo /sbin/reboot
This worked.
After rebooting, I tried log in with the GUI login screen. However I just cannot login. After I input my password and press enter, login screen goes black out and comes back to the login screen. I also tried to log in from console (Ctrl+Alt+F1), and it worked. I can log in.
I am using kubuntu 10.04..i am a new guy here..
i unfortunately removed all my files from /home folder..
rm -rf ~ /. picasa / (ya..i know..)
As some of the files were really important i tried recovering data using foremost..i used the command
foremost -i /dev/sda1 -o /mnt/foremost
After execution of this command it prompted a process..it was downloading something..and i left the computer for an hour or so..when i return there was nothing on screen..so i reloaded the system..And after that when i try to login i get the error
"xsession: warning: unable to write to /tmp; xsession may exit with an error"..so when i googled for it i found its because there is no memmory in my /root ..so i tried login via console (tried ctrl+alt+f1..after the login screen appears..when i type ctrl+alt+f1 i get a black screen)..but nothings happening...
but the problem is when i type (ctrl+alt+f1) i am getting a black screen only...and just a cursor blinking..nothing else..ctrl+alt+f1-f6 give me the same result..and when i try (ctrl+alt+f7) it goes back to the screen with the error....how can i login to console now...
Just loaded Lenny, mostly with defaults. I'd like to go back to a command-line login for the console attached to the machine. Of course, I'd like to be able to 'startx' whenever I do want the GUI up.

On the console I can switch the ttys and enter my login credentials. After that I see the GNU/Debian Linux welcome message an no prompt. The system seems to hang. I'm able to switch the tty again and login with the same result. (I tried that three times now and I start running out of ttys.) A search on the Internet suggested some ressoucre shortage. How could I release some resoucres than? How could I further investigate the situation before just trying a hard power off?
I have Ubuntu 9.10 and I want to activate the login screen by console. I know I can do it graphically:
System -> Admin -> Login Screen
But I need to do this through line console.
Is there anyway I can automatically login to console without having to provide username and password as soon as I boot into the machine?
