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

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 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.

A few minutes ago I was using google chrome when suddenly the scroll-lock indicator on my keyboard turned on... I pressed the scroll-lock key, but nothing happened, the light remained. I opened a terminal and ran "top" to find what processes were running when I was automatically logged out. I logged back and checked the logs and found the following entries in my auth.log:
Code:
CRON[2971]: pam_unix(cron:session): session opened for user root by (uid=0)
CRON[2971]: pam_unix(cron:session): session closed for user root

2) i can use recovery mode boot and log into terminal as root(startx is not working from this terminal..
I login as normal user. I can 'su root' fine - password authenticates. However, If I try to run System->Administration->Users/Groups, when it asks for root password, it is rejected. When I run updater, it reports failure to authenticate, but doesn't even ask for root password beforehand. Is there a cached password someplace?

I didn't use Ubuntu for a long time for this issue.
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.
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 ?

View 4 Replies View RelatedI'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.
My desktop won't come up automatically now on a hard disk of mine (see below for the Ubuntu version history). It does boot up with Grub etc; then the Ubuntu load up bar thing with the timer spinning around [I hope you can understand this technical language!] goes through ok but then instead of getting the user interface with the little boxes to enter my login and password, the whole screen is in black (as if it's in Terminal mode). This black screen then asks me for my login and password: when I entered them, it said:
Starting up......loading, please wait
19 + 0 records in
19 + 0 records out
kinit: [followed by a load of technical stuff and a series of numbers]
kinit: trying to resume from /dev/disk/ by-uuid/9b [then a whole series of numbers]
kinit: no resume image, doing normal boot.

the other day I was playing around with various GDM themes for the login screen without realizing that they're not really supported in the newest version of Ubuntu (10.10). Somehow though, I managed to install one of these themes (not sure how I got it working), and now I want to restore it back to the default login interface. how to go about this without screwing something up.
View 1 Replies View RelatedI've updated my ubuntu from 10.10 ==> 11.04. Now I can't login using graphical inerface. System is loading but it stops right before I should see screen with login credentials. When I use ctrl+alt+del it's going to reboot properly, the same when i push the power button it's shutting down. System works fine in failsafex mode so I can assume there's a problem with xserver etc. Using Nvidia 9500GS.
