difference b/w a login shell and a non-login shell ?
I know that when we use su - <username> we are getting a login shell & when we use su <user-name> we are getting a non-login shell.
Do we get any additional privileges when we have a login shell compared to a non-login shell ?
I'm hoping someone can help me out.I made configurations changes to/etc/pam.d/system-auth and /etc/pam.d/login. When these files are configured the way they are, I can't login and/or I can't login in the GUI interface and a terminal. Contents of /etc/pam.d/login
Code:
#%PAM-1.0
#line added per security guide

I recently did a fresh install of Ubuntu 10.10 64-bit. After installing the ATI drivers, I had to tweak GRUB to get the nice splash screen back during boot. Then, I installed drivers for my TV Tuner (Hauppauge 2250). The card works fine. However, my boot now goes splash screen to a terminal login for around 10 sec where system messages also show up to the GUI Login screen. I was wondering if there was anyway to return to a normal boot.
View 3 Replies View RelatedI 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.
So I've got this home file server, and I want to display certain stuff using:
top
who
a tcpdump of snort logs, scrolling in real time
I want it to display on the screen using a split terminal screen, so all of the information shows on one display, but I do not want it to be vulnerable to a local attacker. Is there any way I can have these things start up at login, but prevent that user from doing anything other than viewing this information?
I'd like to change the login thing on the left of the terminal: [james@xxxxxx home]$ But can't figure out what it's called to do a search, so figured I'd ask all in one! What is it called, and how do I customise it in bash_profile ?

I waited a good 5minutes or so, but nothing happened and I could do anything. I had no choice but to do a hard shutdown. After I turned the netbook back on everything seemed normal. It went to the login screen and everything, but after I click on my username and type in my password I just get a terminal in the top left portion of my screen.

View 6 Replies View RelatedI have been running 10.04 since the launch after upgrading from 9.10. Today when I logged in as normal, instead of taking me to the desktop I get a white console on the top left corner with the normal login background. I typed 'sudo X' but it says the server is already active for display 0. Please advise what I can do. I am reasonablyew to Linux so apologies if this has been discussed before (but I couldn't find any info here or on google).

View 9 Replies View RelatedI enabled auto-login on my netbook without considering that my /home partition is encrypted, so now I can't log in. Is there any way I can disable auto-login without using the GUI?EDIT:I was able to get around this by going to a TTY, logging in, then killing X and starting GDM again. Still, this is not acceptable. Subscribe to the bug here, if you agree with me.

View 2 Replies View RelatedI am aware of how to run scripts on startup, but I don't know how to do the following everytime ubuntu starts up:
1. automatically open a new terminal window (I know how to do this)
2. automatically run a specific script in that terminal (I want to leave this terminal open indefinitely)
I've seen lots of posts all over the Internet that advise users to check the "Run command as a login shell" checkbox in GNOME Terminal under Edit->Profile Preferences->Title and Command.
This makes gnome-terminal run bash/csh/tcsh/ksh as a login shell, which it does not do by default. In turn, running gnome-terminal as a login shell sources the system and user login scripts. This sets up things like colored ls etc.
It seems like gnome-terminal should be a login shell by default. Why isn't it? I've never seen a good explanation of why gnome-terminal isn't a login shell. The "Run command as a login shell" checkbox must be unchecked by default for some good reason, right?
I am new to Ubuntu and been trying to download some software not in the Software centre but when I go to terminal and I enter the command text I get prompted for my password ( it automatically has my login name) but the flashing cursor will not allow me to enter any text ,it just keeps on flashing but then it tells me I have entered incorrect password, What can be the problem ? The keys are not connecting with the terminal window it appears.

View 4 Replies View RelatedI have a 'special script' in my .bashrc file, which I want to be performed only at Login. When I open a terminal (through a gnome launcher <gnome-terminal> as the command) it unfortunately sources .bashrc.
Hence the opening of the terminal runs the 'special script' again.
How can I instruct .bashrc not to do something except when and only when I am logging in? I found a segment of code which is supposed to do what I want but I am not sure of how it works.
Code:
Will this work to put my 'special script' in to ensure that it only runs when it is a login script and not when it is a simple launcher terminal opening?
So when I write my password in a terminal the letters occur in clear not ***(star). what shall I do that enetering the password to work right.I want to say if I push key f for example the system to show me one *.I know it's easy but really I forgot .

View 2 Replies View RelatedI recently set up a family computer for a friend, and now his son is "experimenting" with the terminal (randomly entering commands). since he could accidentally do something bad, I am supposed to prevent him from using terminals, but only as hi user.

View 9 Replies View RelatedI've had a couple Ubuntu 8.04 servers hang hard with no terminal response.
After a given time the terminal login screen will go blank automatically. I'd like to prevent that from happening in order to hopefully catch any messages that get output to the screen before these hangs occur. Currently when the server hangs, I can mash the keyboard all I want, the screen stays blank.
I've tried 'setterm -powersave off -blank 0', but that doesn't seem to hold after logout.
When I login, all I get is a terminal in the upper left-hand corner of the screen with the wallpaper in the background.
I uninstalled what I thought were random orphaned packages relating to evolution (evolution-data-common, etc..) Turns out that this uninstalls gnome-panel as well, although it didn't warn me. Reinstall gnome-panel and it will reinstall the required packages (you can still run synaptic from terminal!)
I can boot up ubuntu but it's just showing the default background, the login prompt won't come up. What do I do? Startx doesn't work in the terminal (ctrl-alt F1), it gives an error. I can log in as root (recovery mode) and startx works and the desktop comes up though.
