Security :: Sudo Non-user/non-root Password?
Feb 19, 2010Stumped on this one. I'm trying to set up limited sudo authority on a desktop with some sensitive user data, and as an extra precaution I wanted to configure sudo to use a password other than the user's or the root's. I'm not sure how to do this. From the manual, we have a few options, such as "runaspw" or "targetpw", but none seem quite what I'm looking for.For instance, "runaspw" could be used if I created a user for nothing other than sudo(ing) purposes, but it requires you set "runas_default", which means that said user would have to have authority to execute said commands in the first place. This is workable, but seems like a lot of extra configuration for each specific command that I want to run, as well as creating some issues with simply commands such as "shutdown" or "reboot". Also, "targetpw" can be used in conjunction with a sudo(ing)-only user if I set an alias, but, again, this isn't quite what I am looking for.
Ultimately, what I am really concerned about in this situation are keystroke loggers, so I would prefer to avoid repeated entering the user or root password when performing administrative tasks. Also, I would prefer not having to create a sudo(ing)-only user as mentioned above to prevent a comprimised password resulting in an attacker being able to log into my system.

Jul 12, 2009I'm not necessarily gonna do this, but I have to know. Is there a way to make the system not complain about every single freaking password you try to use? Make it so that any regular user could make "hello" their password without complaint? Like I said, I won't necessarily do it, but I have to know if it can be done.I did some searching and found the su -c "passwd username" trick, which is working for right now (I have root access but a user account I made for a friend doesn't)... it's just irritating when it won't even let him use something like "snuh123" because it seems to think it's based on a (reversed) dictionary word. Any use of a dictionary word, even with other chars, fails

Feb 22, 2010I 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?

Sep 20, 2010I want to use root password instead of adding my user to the list of sudoers,In Arch wiki ander Root password:Users can configure sudo to ask for the root password instead of the user password by adding "rootpw" to the Defaults line in /etc/sudoers: but that did not work for me. it asks for root password.Why do I want to do that:
1. I want to do that, I like sudo more than su -c 'some_command'.
2. sudo enables bash completion, su -c does not.
3. I don't want to add my user to sudoers list.
I found many users Suggesting alternatives and lowering the important of my need for this, when I asked this question in anther please.

Fedora Security :: Root Login Via Ssh 12 Password Authentication?
Jan 27, 2010Can't seem to do it, wondering if anyone knows how? Normally there's something in sshd_config that can be switched to true or yes to allow root login but I can't see it in fedora 12.I can login via root at a terminal no problem, just not via ssh, I get access denied every time. Also, I need to login using password authentication.I've done: 227169 but that's just for GUI which I don't really need since I rarely ever log into the GUI.I have also searched through here and mostly only found info such as above, how to enable root login for GUI, or billions of posts about how logingin as root is bad but I cannotswer to my question.DISCLAIMER: Please do not reply to this thread if all you can contribute is the question of why I need root or to put some message telling me I can do everything using su, etc, etc. Please only contribute if you can answer my question. A: My machine and a valid quesiton. B: Spirit of Linux is open, not restrictive

View 3 Replies View RelatedFedora Security :: Suddenly Root Password Invalid For Su Command?
Apr 9, 2011I have recently installed Fedora 14 on a new computer we presented as a gift to my sister-in-law. She is new to Linux. Although I've used Fedora since Core 1, I'm no expert on security issues, and this baffles me. She's doesn't know how to change the root password, so why doesn't it work any more? She discovered the problem when attempting a yum update from a terminal.(1) How could the root password have gotten changed? How likely is it that someone got onto her system through ssh, made a lucky guess on her root password, and then changed it? Are there robots that do this?
(2) The firewall is enabled. I have it set up as follows: (a) under "Trusted Services," only ssh is checked (I need to be able to get in remotely this way); (b) under "Trusted Interfaces," I have eth0 checked (I need to be able to use VNConto her desktop).Question: Are these settings giving ample protection? What settings would be recommended to protect her system while at the same time allowing me to access it through ssh and VNC?

Oct 26, 2010I no longer have access to my root desktop. On a session I attempted to change the root username but i apparently assigned it a wrong directory that does not exist. When I rebooted with my new root username, i was instead recognised as a simple user (no root privileges). I tried the console to change to "old" root but root password is not accepted and there is no way to access to sudoer files. it seems that inserting a new username requires root privileges and i am back to square one. Simply logging with old root username and password after restart gives me a blank screen with nothing on it and cannot even reboot.

Red Hat :: Cannot Change Root Password (let Alone Standard User's Password)?
Jan 6, 2009At the RHEL prompt, I entered the standard user's username/password combo. Linux displays a message box stating:"Your account has expired; please contact your system administrator."Next, I entered "root" in the username field and entered the root password (which expired also--keep in mind that passwords are set to expire after x days). Linux displays a message box stating:"You are required to change your password immediately (password aged)."When prompted to "Enter current UNIX password", I entered the new password (was that the right thing to do?); Linux displays a message box stating:"The change of the authentication token failed. Please try again later or contact the system administrator."I rebooted the system and got into command line mode; somehow I logged in as "root" (don't know exactly how, but needed to change the password there). At the "#" prompt, I type "passwd root"; Linux displays the message "Changing password for user root", followed by the message "passwd: Authentication information cannot be recovered.

Apr 17, 2009Being able to reset the root password by booting into single usermode by editing grub. This is a MAJOR flaw. I know it makes no real difference against internet bourne attacks, but even so I must say I found it shocking. The only way I've found to stop this is to encrypt the entire HDD, so noone could get into single user mode without first knowing the encryption key/password.
