Security :: Login Password Upon Starting?

Jan 19, 2011

I installed linux system into a USB stick, but it never asks me to enter login password (i am the default user "root") when booting. I checked the settings in "User and Group" panel, and found everything there is OK. What additional settings should I make to this problem?

Ubuntu Security :: Bad Login Protocols - Graphical Login For Gnome Sizes Itself To Accommodate A User's Exact Password Length

Dec 14, 2010

I'm seeing really bad user login format under a standard installation and am wondering why ubuntu does this as default. I have noticed that the graphical login for gnome sizes itself to accommodate a user's exact password length. This indicates to me that somewhere on the unencrypted part of a standard installation with user encryption contains at least some indication of the content of the password length which seems a security flaw even if not a complete hole, it majorly reduces the number of attempts a cracker would have to cycle through.

And that's assuming that *only* the length is contained. Furthermore it seems that it would be MUCH better to simply display the number of characters entered into the pw field and allowing the gui to expand itself from an fixed size as the field is filled out so the the user still receives visual feedback for entering characters. Either a simple character count display should be entered into the field or a 10 dot to new line so that one can visually quickly count the number enter by multiplying from a 10base graphical observation.

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?

Security :: The Login Password Echoed - How To Correct It

Nov 25, 2010

Kernel 2.6.21.5, Slackware 12.0
GNU bash 3.11.17

Being in a text console (VT, that is, the screen with 25 x80 chars), say tty1, and just after booting linux, I logged in as usual,typing my password.What happened then astonished me. In Slackware distros, a small quotation from some book is written on screen just after typing the correct password. Well, after typing my password, I could see it split into two halves instead of the quotation.

Security :: SSH Login Without Password Not Working As Expected?

May 5, 2010

There is this one server running CentOS5.4 Final which has certain application like Bugzilla. I have setup ssh on it and setup is for password less authentication. Have also setup PasswordAuthentication to no. So with password authentication should succeed. But it is. Though password less authentication is working fine, but I am also able to login using password.

Code:

RSAAuthentication yes
PubkeyAuthentication yes
PermitEmptyPasswords no
PasswordAuthentication no

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

Second off, I'm trying to capture a user password on login (through gdm) such that I can re-use it for a service like Kerberos or AFS. The idea is that the user has to log in only once, and then I renew the tickets and tokens until they log out again. If there's a better way to do this

Ubuntu Security :: Home Folder Encryption Using Login Password

Mar 20, 2010

When installing the latest Distro of Mint (I believe this is not much different, if at all, from Ubuntu as far as this goes) I chose to have my Home folder encrypted using the login password. This was a function of the installation. What I was wondering about was how secure this was and if I should maybe use something to do a better encryption or not.

Security :: PAM Module - Allow A User To Connect To A Server Via SSH With Any Login Name Or Password

May 5, 2010

My goal is this: Allow a user to connect to a server via SSH with any login name or password without checking to see if that account exists on that server. Their account would be captured by a universal account say, 'generic_user', and then they would be directed to one of my python scripts with the username and password they supplied for initial login. At this point my script would capture their SSHD process ID and allow/deny their existence based upon a MySQL/Subscription check.

The part I'm having trouble with is with PAM and allowing the user to login with any credentials and be successfully authenticated under the generic account. Beyond that, everything is great.

Security :: REDHAT Missing Functionality - Force User To Change Password On Login?

Mar 16, 2011

I have now been trying to find an answer for the following for a while and can't seem to get anything.On previous linux distros we had the option available "passwd -e" which allowed us to force the user to change their passwords upon the next login.s functionality however seems to be excluded from latest linux distros (currently using RHEL 5.4)...Does anybody know how the same effect can be achieved and perhaps any idea on why this option was removed as it was great for securing passwords

Is that correct?

OpenSUSE Network :: Login Uses Local Password Instead Of Nis Password?

Jul 2, 2011

I have setup a nis server and client. At first I didn't have a local user defined on the client. The client then used the user and passwords from NIS, so that was ok.

The problem then is, that when the server is down, I couldn't login to my client anymore. So I created a local user with the same name on the client but with a different password (after I shut the nis server down, if nis server was on, I couldn't create a local user with the same name). I then edited etc/nssswitch.conf as follows:

Code:
# (like no NIS server responding) then the search continues with the
# next entry.
#
# Legal entries are:
#
# compat Use compatibility setup

[Code].....

If NIS server is on: client has to login with the nis password If NIS server is down: client has to login with the local password (as fallback)

However the actual behaviour is that I can only login with the local password now. The NIS pasword doesn't seem to be used anymore.

Ubuntu :: Sudo And Login Password Recognized - Password Box Does Not Like

Apr 27, 2010

I 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?
