Aug 9, 2010I've recently installed 64bit version of ubuntu 9.10 but the GDMsetup doesn't seem to be working as it was in 9.04 i mean to say when you type gdmsetup at console the login window pops up where i can check the check-box "Allow local administrator log in" under security tab. to enable login as root. since it is not working i've to type password every time when i install a package or create a folder in root directory or mount a drive which is quite irritating how can i login as root in gui mode etc... also is there some syntax which i can put into /etc/gdm/custom.conf so i can log in as root....
View 2 Replies View RelatedUbuntu Security :: Using Root As Daily Login?
Jan 22, 2011It'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.
Ubuntu Security :: SFTP/SSH Alternative To Root Login?
Oct 20, 2010On 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

Security :: Able To Locally Login As Root With ANY Password ?
Jan 20, 2010Found 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?

Be warned if someone actually does manage to login as root on your computer or server.
Edit .bash_profile for root. How do I do this?
Code:

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.

Feb 2, 2010For 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)?

Apr 22, 2010we are trying to make a policy decision whether to go with SSH user/passwd or PPK secure key ? our servers are hosted remotely by a hosting service. we were wondering which of these two models are more secure.e.g. i would tend to think that user/passwd with account lockouts upon failed attempts would be more secure because the other option exposes your server in case someone sneaks the PPK file or steals your whole computer.however, what makes me doubt myself is that Amazon Web Services EC2 cloud hosting uses PPK by default (although an instance's SSH config can be change to accommodate logging in but they don't endorse it).

Security :: Deleted File Stripes / Log Into A Passwd Less Acct?
Jul 2, 2010I work for a seismic company that has recently experienced a security issue. Because we have an isolated network that is used for HPC work we have a very open security structue ie password less accounts rsh rlogin etc. We had, seemingly,a user that has maliciously deleted another user's files but I still haven't figured out how. So far I have been able to prove that this user has remotely logged into another host under that user's account... or at least that their workstation did. The /var/log/message file shows logins from their workstation as that user multiple times durring the times that these files were being deleted. There are wildcard searches for these files in the history in this host. There is a vi session initiated on this host for a file called delme (delete me) and then a chmod +x for this file. and then a deletion of this file (rm delme). Funny things: this user has no business in this acct. this user was bounced off the other host (permission denied) when trying to log into the other host and then as root logged into the other host as the other acct. repeatedly... ie. rsh -l xxx (permis den) then as root rsh -l xxx (logged in) why not su xxx and then rsh? password less acct?! why use root privs (which they sholuld not have) to log into a passwd less acct? Can't see any remote logins to their workstation from elsewhere. can't find smoking gun. no execution of delme script or any other rm /*/xxx/* sort of command that proves when file deletion of striped files happened?!
changing root passwd soon.need proof that no remote logins to a CentOS 5.3 workstation could be responsible.
Could mean someone gets fired.how can I be sure that no other users logged into this machine and then into another machine for sure?
