Fedora Security :: Disable Logging In As Root In Console?

Feb 22, 2010

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?

Fedora Security :: Root Login Via Ssh 12 Password Authentication?

Jan 27, 2010

Can'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

Fedora Security :: Log Files Empty - System Does Not Allow Root To Login ?

Feb 2, 2010

For a month or so now, I have been enabling ssh and opening port 22. I cron'ed the start and stop commands to leave them open only a few hours a day. After a bit, I checked my logs to find that some IP or another was attempting to brute force my root account.

I took little real threat by the offense.

(1) my system does not allow root to login and

(2) it would cut them off sooner than later when my system issued the stop command.

fast forward

Today I log in to find that all of my log files, as viewed from the gnome log file viewer, were empty of entries from about noon yesterday and prior.

Though I haven't noticed anything at all out of the ordinary with my system, I would like to get more opinions on the matter. Would there be any conceivable way that this was an automatic system routine, a clean up action of something? Additionally, if I was indeed the victim of a hack, what can I do to further protect my system (keeping in mind that I do want to access my system via ssh from time to time)?

General :: How To Disable Root Login (Not Over SSH)

Nov 26, 2010

I 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.

Code:
# lsb_release -a
LSB Version: :core-3.1-ia32:core-3.1-noarch:graphics-3.1-ia32:graphics-3.1-noarch
Distributor ID: EnterpriseEnterpriseServer
Description: Enterprise Linux Enterprise Linux Server release 5.2 (Carthage)
Release: 5.2
Codename: Carthage
[root@~]# uname -a
Linux TomcatServer 2.6.18-92.el5 #1 SMP Fri May 23 22:17:30 EDT 2008 i686 i686 i386 GNU/Linux

Ubuntu Security :: Cannot Disable Auto Login?

Jan 22, 2011

I have tried everything to disable automatic login from the login screen (gdm). I've changed my password, I've changed the settings in System -> Admin ->Login Screen, and I've edited /etc/gdm/custom.conf (gdm.conf doesn't exist, but I created it just in case!).No auto login is set up, but I can't get it to ask for my password. This is affecting my ability to switch sessions, as I can't switch sessions without clicking on my name in gdm, and because it's set to auto login,

How do I disable showing Usernames? I want to be prompted for BOTH un and pw. If it is necessary I could just change it so that it boots into a fullscreen terminal so that you would have to input "startx" and then username and password. Or I could just change it through gui or 3rd party software.

Security :: Disable First Level Login Via Putty

Sep 4, 2010

Is there anyway I can disable an account from being logged in via Putty, but permits someone else to "su" into the account? For example, an application is being run as "app_account". Because there will be multiple people administering this application and the password is shared for this "app_account", I want to disable 1st level login for it. I want to make it such that only the permitted people can "su - app_account", once they have logged into their personal account. How can I do this? If I set app_account's shell to /sbin/nologin, the users are also not allowed to do "su - app_account".

Security :: SSH Time Out On Login Attempt From Remote Box: Command Needed To Check Port 22?

Dec 1, 2010

I have set up a user to login remotely to our Red Hat 5 server via SSH. A rule in our department firewall enables this user to login from a single static ip address. The ssh port on our server is 22. I am able to login to port 22 from locations within our department firewall. Our administrator says the firewall configuration is unchanged. The remote user had been successful logging in. But now the remote user gets a Connection Timed Out message, before being asked to authenticate by the server.

I regenerated security keys, but the remote user still gets the connection timed out message. (I can login locally with the new keys). I suspect either a firewall or an authentication problem--inclining a firewall problem. Am I correct? Is there a Linux command to check whether port 22 is available or blocked, prior even to authentication, for login from the user's remote location?

Ubuntu Security :: Using Root As Daily Login?

Jan 22, 2011

It's my personal computer, no other users, no one else in the house. I'm behind a separate stand alone firewall (Checkpoint device). I'm the admin on my machine and I'm going to enter sudo, or login as root, every time I need it anyway.

There's no way that having to switch to root is going to make me stop and think about what I'm getting ready to do. In fact it's quite the opposite. If I'm in the midst of troubleshooting, I'm preparing to enter a command that I think is going to work, and I get "Permission denied"... The aggravation is more likely to reduce my logical thinking, and I'll immediately switch to root and type it anyway.

I DO understand the rational of setting users (even admin users) to a lower permission level. However I don't understand the lack of a command to make a user PERMANENTLY root equivilent. Switching back and forth is a waste of time. AND it means that I now have to deal with two home directories... /root and /home/user. Having to type sudo, or su to switch to root, does not protect my system. It only aggravates.

Security :: Able To Locally Login As Root With ANY Password ?

Jan 20, 2010

Found a major security hole in one of my more crucial linux servers today. (Only locally) I can use the user name "root" and any string for the password. So I can literally type "poop" as the password and the server lets me in. I know how to set root password settings for SSH and sudo, but where are settings located for local access that would allow something like this?

Ubuntu Security :: SFTP/SSH Alternative To Root Login?

Oct 20, 2010

On my Ubuntu 8.04.4 LTS webserver I desperately want to disable the Root account. But at the moment I am unable because I prefer to use Nautilus/Dolphin on my home laptop for SFTP. The graphical interface also helps when comparing multiple config files at once, something that being limited to NANO or PICO would make extremely painful. The problem is that if I don't use ROOT I can't perform any SSH or SFTP actions with a graphical interface, because I can't use SUDO without the terminal. Does anyone else leave root enabled? I have a non-standard port, disabled password authentication in favor of ssh keys, and I have a tarpit configured
