Security :: Sudo Asking For Password When It Shouldn't?
May 9, 2011I have a RHEL 5.5 system set up with two users in the sudoers file to run certain commands without a password prompt.I do not have "Defaults requiretty" in the sudoers file.However, for both users, when I issue: sudo -l, it prompts for a password and logs in /var/log/secure:sudo: userx: no tty present and no askpass program specified
View 2 Replies View RelatedSecurity :: Sudo To Root Without Password?
Jan 26, 2011 We have a couple of clusters that are running Oracle. If you're familiar with Oracle you know that it basically has to be installed as root. Something I detest. anyway, when we are building out the box, we change the root pw and give it to the DBA team to do their installs and configs. When they are done, we change the root pw (and do not give it to them), and configure sudo to allow them the rights needed to manage Oracle and their databases.
Now however, we have a different situation. The DBAs need access to uninstall and reinstall components and make modifications on an ongoing basis. Since we only support OS and hardware, not app, they are requesting permanent root access. I promptly told them no, and the politics ensued. Their manager went to their director, who went to my director, and suddenly an exception is given for his good golfing buddy. So here I am, forced to turn lose DBAs on my clusters with full root access/pw. I need a way to allow specific users (or perhaps a specific user group) the ability to become root WITHOUT sharing the root pw with them.
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.

Fedora Security :: Cannot Open /var/db/sudo After Sudo Package Upgrade?
Sep 16, 2010A day ago I finally got around to upgrading the PackageKit installation that had been sitting for a week and a half, so I found a new upgrade for sudo available - the one that gives the sudoreplay command, I forget which version number it is exactly. When I try to use the sudo command I get this notice in my terminal:Code:Can't open /var/db/sudo/me/1: Permission deniedI didn't get it before. What do I have to do to make it open? I'm using SELinux in enforcing mode if that helps.
View 1 Replies View RelatedUbuntu :: Sudo And Login Password Recognized - Password Box Does Not Like
Apr 27, 2010I needed to use Synaptic Package Manager to install an app, but the dialog box ("enter the Administrative Password") that pops up before you can use Synaptic doesn't recognize my password ("incorrect password). I tried typing it into a text editor and it's spelled right, caps lock not turned on or anything.
In Terminal, sudo recognizes it, and it is recognized when I log into Ubuntu. I'm the sole user, I have admin privileges, I've been doing admin things.
I just now did System > Administration > Users and Groups and got a dialog box saying
"Failed to contact configuration server; some possible causes are that you need to enable TCP/IP networking for ORBit, or you have stale NFS locks due to a system crash. See [URL] for information. (Details - 1: Server ping error: IDLmg.org/CORBA/COMM_FAILURE:1.0)"
Moving past that, I changed my user password, and Ubuntu authenticated it.
How do you launch Synaptic Package Manager from the command line?

View 9 Replies View RelatedDebian Configuration :: When User Is Admin Root Password Is Still Needed
May 7, 2015I'm using Debian Jessie Cinnamon right now. I've got 1 user account on my machine--fred--as well as root, of course. "fred" is an administrator, and many times that is enough for root priviledges, for example, I can install packages via apt or dpkg. However, I cannot access "Users and Groups", or install packages via GDebi, with my password. For that, I have to have the root password.
I know that it is possible to let the admin account handle everything and not even need root--for example, Mint and (I believe) Ubuntu do it this way. I don't know how, though.
Code: Select allgroups fred
fred : fred cdrom floppy sudo audio dip video plugdev netdev lpadmin scanner bluetooth
I did disable the root account by Code: Select allsudo passwd -l root to see if it would make any change. Nothing different happened except that I now can't use GDebi or access "Users and Groups" since the root account and therefore password is inactivated. Not a big deal to get it back, though.
OpenSUSE :: Update Applet - Su / Root Password Always Needed (GNOME)
Apr 30, 2010I have a minor problem with my "Update Applet 2.28.0" in Gnome. It occurs when I want to make the applet do one or more suggested update(s). It always asks me for the password of superuser/root: "Authenticate : Authentication is required to update packages. [...]". I think under my installation before (11.1 maybe updated from an older version) I could tell the automatic/semi automatic updater to remember the su password (in YaST or in the authentication dialog?).
In the help manual on my computer (and in the internet) there is the possibility to make the updater remember the password via policy kit: ("Access to all privileged operations is controlled via PolicyKit." See: GNOME Documentation Library : gnome-packagekit Manual : Introduction) I could not find any policy kid or any other possibility to give to the automatic updater (or its user) that privilege permanently (=to remember authorization). I think on a system with more (real) users this could be a real problem (not just an inconvenience).
Fedora Security :: Terminal Equivalent Of "sudo" Is It Still Sudo/KDEsudo
May 29, 2010I am new to fedora (been using debian based distro's for the longest time). With the new release I decided to give FC13 (The kde 64 bit spin) a try. I told it to wipe my entire hdd and encrypt the partitions. The partition manager made a few LVM partitions which I assume are encrypted.
The problem I am having is that if I attempt to use an application that would normally need root access to run, I am not prompted to enter my root password. Instead, I am required to logout and log back in as root. Is there a way to make it so that FC13 will prompt me to enter in my root password so I do not need to log in and out? Or is there something Different I should have done during the install process? Also, what is the terminal equivalent of "sudo" in fedora, or is it still sudo/KDEsudo
I also have not used SE Linux before. Do I need to manually enforce the permissions for my applications and generate my own profiles for it, or is that done automatically?

Security :: SSH Time Out On Login Attempt From Remote Box: Command Needed To Check Port 22?
Dec 1, 2010I 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?

May 4, 2010I installed Ubuntu 10.04 as a vm in VMPlayer 3.0. My correct user password is required to log in. When I use the sudo command or enter an area that requires my password, the password box pops up as it should.
The problem is:
If I enter my actual password, it is not accepted.
But if I enter nothing, as in just hit enter, it works. It shouldn't.
That seems just a little backwards and I don't get it. I've re-installed the vm and still have the same problem.
Ubuntu Security :: Generate Password / Encryption Keys For Password
Oct 22, 2010I know this has probably been asked too many times here but I need to secure my emails. Personal matters of course. But yeah. I use the program "Password and Encryption Keys" to generate a key to sign my emails with but I do not know what to do. To be blunt, I'm stupid when it comes to this. IF not, steps in creating a key? and giving it (my public key) to the significant other? Finding where both keys are? Implementing it into Thunderbird?

View 5 Replies View RelatedUbuntu :: Sudo: 3 Incorrect Password Attempts
Feb 7, 2010My root filesystem recently filled up. I finally established why - that my /media directory had filled up due to the USB-attached device having been unmounted for whatever reason, and SimpleBackup tried backing up without the mount in place - thereby filling up the filesystem.
I discovered that the root directory was full when the machine tried to get updates, and couldn't. So, I went into /media and tried to delete the backup directory and file(s) that were in that directory, but it tells me that permission is denied. So I try to SUDO the same command, and it tells me 3 times in a row, "Sorry, try again", followed by "sudo: 3 incorrect password attempts".
So, how to I get root privileges back again?
Code:
name@machine:/media$ sudo rm -R FreeAgent
Sorry, try again.
Sorry, try again.
