Ubuntu Security :: Root User Built-in Protections?
Jan 30, 2010
Any Linux machine (except PCLOS) that I log into as root user seems to not start networking. I haven't tried sudo /etc/init.d/networking restart , to see if it does start, because anytime I DO this, it's for 'local' work. How about default root user configuration settings???

Having trouble adding a regular user with ssh access on Hardy 8.04. I can ssh into root, but not into the newly created regular user with the same ~/.ssh/authorized_keys
Code:
sshd_config has:
AllowGroups sshlogin
AllowUsers user root
[code]....
what could be preventing ssh login to ~user? And yes I would like to disable root ssh access, but it would be nice to be able to ssh into user first

How do I add root permissions to my user account?
I want full permissions for all computers in my house, without having to get up and go to the other room and change permissions for the file, folder, drive, directory, computer, etc., then go back to the other room again.
I just created a partition, as THIS user, THIS machine, rebooted, and cannot create a folder on the partition I just created. UGH. No more of this stuff... I guess at the very least, I'll still have to log onto each machine for this?

I am trying to run su as a non privileged user to log in as root. However, this only works when I make /etc/shadow world readable. I have /lib/security/unix_chkpwd as a setuid root executable
I use the following pam-file for su:
Code:
# Begin /etc/pam.d/su
auth sufficient pam_rootok.so
auth required pam_unix.so
account required pam_unix.so
session optional pam_mail.so
[Code]...

i want to know the risk with auto mounting flash drive as a root user,if for example there is a Usb Flash drive inserted into the system and we login into root unknowingly, and this flash drive contains an autorun script which calls a new script that can place viruses in your system, since you are in the root it will not even prompt for password and if the script is fast enough you will not even see it executing.

Can the audit daemon (auditd) be run by a non-root user? I'd like to create a special user who only run the audit daemon. Is that possible?

Senario is we have a system where root has authorised keys set up so that it can do a passwordless ssh to $WORKSTATION. I then need to run a script on $WORKSTATION as user "bob" and NOT as user "root". I do not want to set up user "bob" to be allowed passwordless ssh so any ideas how I can do this?I have tried variations of (as user "root"):ssh $WORKSTATION "su - bob; ./my_script"

Stumped 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.

My understanding is SELinux adds type enforcement to standard Linux. This means that both the standard Linux and enhanced SELinux access controls must be satisfied to access an object. Which means that thing that is prevented to do in the normal standard Linux will be also prevented in the SELinux System? Does SELinux make it possible to run a non-root software to bind to a port < 1024? something that standard Linux won't allow? If not, what other suggestions do you have for allowing a program to run as non-root but able to bind to privileged ports? I know all about using the port re-direction such as ipchains, iptables.

In our group we use NIS and have a group set up called netadmin which is given root privileges on each machine. Each machine also has a localuser called localuser created and used during installation. When logged in as a member of netadmin, attempting any action that requires root privileges (e.g. installing software in Ubuntu Software Center) results in a prompt asking for localuser's password, not the current user's password.
Does anyone know the cause? Configuration issue or Ubuntu issue? We can get around it.

I'm using Gnome and I'd like to still have the ability to reboot/shutdown from one particular account as well as root. How would I modify the chmod command to add this ability?Also, I have a few users who just will hold the power button in to shutdown the machine. How can I keep them from doing this?// Pruned from the vintage 2007 Prevent a non-root user from shutting down, rebooting or suspend the system thread. Please create new threads instead of resurrecting ancient ones.

I 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.

want to run VirtualBox with root permissions. Trouble is that only when run as root i can access attached USB devices inside of a virtual machine, otherwise, these a greyed out).Now running VirtualBox as a root user also changes the configuration folders, making all my virtual machines already defined disappear. I also don't want to copy all to the root configuration folders. Is there a way to give the VirtualBox root permissions but without actually running the application as a root user. Is it possible to do without changing the permissions of the non-root user, i.e. i don't want my user to have all root permissions, due to security considerations.

A friend of mine has told me to set a root password and use root (f.e. switching to su in terminal and work with root rights instead).Is there any way to unset the root password? I know how to use sudo now.

Prelude: OpenSUSE 11.2 (2.6.31.8-0.1-desktop), installed Novell client 2.0 SP2 (novell-client-2.0-sp2-sle11-i586.iso).
I found that if any usual user is logged into a NDS-tree, then _local_ root has full access to user's network shares, including the user's home directory located on remote Netware-server. Is it by design or
have I missed something? Nevertheless in windows local admin has no access to network resources mounted of any other user. If you runas shell (as admin) then admin in principle can't "see" network shares which were mounted (connected) by other users - they are accessible ("visible") per session.

I am using mint 8 for a 2 weeks, I am noob to linux but I like Mint than any other linux distro which is great alternative to windows. I have a problem regarding password reseting.
1. My laptop automatically get logged in without asking user name and password.
2. I tried to change password for newly created user and root user using graphical way but it does not work.
2. I can perform administrator task using only OEM user which is default inbuilt user of mint.
How can make my laptop to ask password when mint get booted? How to change password for other users?

Having read on the forums about some of the dangers of running Wireshark as root, I would like to know if anyone can suggest some alternative packet sniffers/network analyzers which will offer similar results but without the security issues. I am using Karmic Koala on a Fujitsu Siemens laptop with wireless router (firewall enabled)
