Fedora :: Root Login Works At Shell - Auth Error When Running Admin Tools
Jan 25, 2011I 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?

Jul 26, 2011I work with a text mode debian6.0 and when I was testing some commands, I changed default shell to ash. System replied that it has not ash shell.so I thought the shell did not change. But when I start the system again and enter root password, I see a message like "can not execute ash. No such file or directory" and then system return to login page again. Root is the only user on that system.

General :: Login Shell And Consequent Subshells
Jun 13, 2010When we are asked for password while booting Linux, is that the login shell ? If yes, we can't seem to be able to do anything in that shell besides typing the password. (Is it in this that the contents of /home/.profile file gets executed ? in a sigle PC)
When we click on the terminal icon for the first time, are we opening a subshell of something or a new shell altogether? If on repeatedly clicking on the terminal icon, new shells are being launched, not sub-shells, then why does export seem to work with the new shells, though its supposed to work for subshells ?

Ubuntu :: Make A Shell Script Run With Root AND Non-root Priveledges?
Jul 28, 2010I have a bit of a dilemma.
I'm using XFCE and it doesn't by default lock the screen before hibernating. I see this as a bit of a security risk, and as I can't hibernate while the screen is locked, I'm a bit lost as to how to achieve this.
I've begun editing /etc/acpi/hibernate.sh, here's what I have so far code...
If I run with sudo, the system hibernates, but gnome-screensaver will not fire. I can verify this by trying "sudo gnome-screensaver-command --lock". The screen goes black, but is not locked. The screen locks properly without sudo.
So the only solution I can see is to edit /etc/acpi/hibernate.sh in such a way that gnome-screensaver-command runs under the current user, and pm-hibernate is called as root.
Also, when I click the HIBERNATE button in XFCE, how does it call pm-hibernate under root without prompting me for a password? I normally wouldn't be interested in such things, but as it seems relevant to my problem I'm a little more eager to learn

General :: Disable - Non-root Shell Command To Find If A User Account Is Enabled Or Not?
Aug 10, 2011Is there a non-root shell command that can tell me if a user's account is disabled or not? note that there is a fine distinction between LOCKING and DISABLED:
LOCKING is where you prepend ! or * or !! to the password field of the /etc/passwd file. On Linux systems that shadow the passwords, this marker flag may be placed in /etc/shadow instead of /etc/passwd. Password locking can be done (at a shell prompt) via password -l username (as root) to lock the account of username, and the use of the option -u will unlock it.
DISABLING an account is done by setting the expiration time of the user account to some point in the past. This can be done with chage -E 0 username, which sets the expiration date to 0 days after the Unix epoch. Setting it to -1 will disable the use of the expiration date.
The effect of locking to to prevent the login process from using a supplied password to hash correctly against the saved hash (by virtue of the fact that the pre-pended marker character(s) are not valid output character(s) for the hash, thus no possible input can ever be used to generate a hash that would match it). The effect of disabling is to prevent any process from using an account because the expiration date of the account has already passed.For my situation, the use of locking is not sufficient because a user might still be able to login, e.g. using ssh authentication tokens, and processes under that user can still spawn other processes. Thus, we have accounts that are enabled or disabled, not just locked. We already know how to disable and enable the account - it requires root access and the use of chage, as shown above.To repeat my question: is there a shell command which can be run without root privileges which can output the status of this account expiration info for a given user? this is intended for use on a Red Hat Enterprise 5.4 system.The output is being returned to a java process which can then parse the output as needed, or make use of the return code.

General :: How To Disable Root Login (Not Over SSH)
Nov 26, 2010I have already disabled root login over the ssh by modifying /etc/ssh/sshd_config. But how would I disable root login on a server itself. We have implemented LDAP in our environment and our security guide states that root login must be obtained by first logging into the host using his/her own regular userid then gaining root privileges by using the SU.

General :: Unable To Login As Root While To Use The Su Command?
Apr 3, 2011I have a Linux machine which I set up for my personal use at home. I installed Fedora Core 11 a long time ago, and recently I noticed that I am not able to log in as root (I didn't realize this issue until recently since I always have been logging in as a user account that I created during the FC11 installation).When I login as a user account instead of root, I can use the su command with the password I set up for the root account. Even when I'm in GUI mode and try to make changes to the system from the user account, the GUI asks to enter the root password, and I type the password I set for root and it works. However, if I boot the machine and try to log in the system as root, password that I set up is rejected.
I'm very puzzled with this problem because with my limited knowledge on Linux system, I thought the root password and the su password are the same (i.e. when you install Linux OS, you set the root password, and you use the same password for using the su command). I do not know exactly when this problem started, but the only thing that I can think of as a cause of this issue is that I once changed the root password from GUI using System > Administration > Root password since the system one time complained about the low security strength of the root password.
