View 9 Replies View RelatedUbuntu Security :: Bad Login Protocols - Graphical Login For Gnome Sizes Itself To Accommodate A User's Exact Password Length
Dec 14, 2010I'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.

Jan 22, 2011I 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,

Or I could just change it through gui or 3rd party software.

Jul 12, 2009I'm not necessarily gonna do this, but I have to know. Is there a way to make the system not complain about every single freaking password you try to use? Make it so that any regular user could make "hello" their password without complaint? Like I said, I won't necessarily do it, but I have to know if it can be done.I did some searching and found the su -c "passwd username" trick, which is working for right now (I have root access but a user account I made for a friend doesn't)... it's just irritating when it won't even let him use something like "snuh123" because it seems to think it's based on a (reversed) dictionary word. Any use of a dictionary word, even with other chars, fails
View 6 Replies View RelatedSecurity :: Disable First Level Login Via Putty
Sep 4, 2010Is 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".

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.

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?

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.

View 2 Replies View RelatedSecurity :: PAM Module - Allow A User To Connect To A Server Via SSH With Any Login Name Or Password
May 5, 2010My 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.
