View 2 RepliesI 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?
my linux system doesn't have X only console login possible. i would like to deny all user to login from any sources, local machine, remote console (putty, winscp) etc. except root.
i've found something about /etc/security/access.conf and i've put:
+ : root : ALL
- : ALL : ALL
but still users other then root are able to login (via putty for example).
When I start my ubuntu linux system it automatically logs into a user (not root) in graphical mode and it does not asking for any password. when I try to go to the command prompt the password is required. How do I give password for my user. The provider installed the system and not me..
View 5 Replies View RelatedI've updated my ubuntu from 10.10 ==> 11.04. Now I can't login using graphical inerface. System is loading but it stops right before I should see screen with login credentials. When I use ctrl+alt+del it's going to reboot properly, the same when i push the power button it's shutting down. System works fine in failsafex mode so I can assume there's a problem with xserver etc. Using Nvidia 9500GS.

View 5 Replies View RelatedI have a Linux mail server (Fedora). This server was set up long before i joined this organization. Now I have these issues I would request assistance:
1. I am not able to access the Graphical User Interface(gui) on this machine. Startx does not work. I have also tried using combination keys alt+ctrl+f...keys but no progress. As a result am not bale to do some tasks.
2. The clamav that is on the machine has since become outdated. Efforts to update it to latest versions have failed. How do i get to update clamav and protect my system?
3. Because of not being able to access the gui as well as the inability to update clamav have led to my server apparently sending spam mail which in turn have led to my public ip being black listed in a number of sites. Now how can i secure this server so that it stops sending the spam mail and hence avoid future blacklisting?(NB am using postfix and the server sits behind a router which connects to the Internet)
4. I have observed that the server has some iptables rules set but everytime the server restarts the rules stop. I have to manually restart them again to run. How do I sort this?

View 2 Replies View RelatedI am working with ubuntu (linux) and have to create a graphical user interface. The GUI is a 2-D plot that have to plot a point. The point ( x and y co-ordinates) are not hardcoded, and are coming from another file (another piece of code written in c / python). I was thinking to use Glade with c/python to create this. But, I am not sure how to start with this.
View 4 Replies View RelatedIt used to be that this was a service that could just be disabled in System>Preferences>Startup Services, but this is no longer the case it seems. I've tried tinkering with the runlevels in gdm.conf, but haven't had any success with it so far. I've tried commenting out the startup code in the gdm.conf as well. Also no luck.
Most of what I've found are older guides for Karmic and earlier, so if anyone has a more up-to-date solution for how to disable the gdm so I can auto-login to a terminal in Lucid
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.
I have already disabled root login over the ssh by modifying /etc/ssh/sshd_config. But how would I disable root login on a server itself. We have implemented LDAP in our environment and our security guide states that root login must be obtained by first logging into the host using his/her own regular userid then gaining root privileges by using the SU.

View 5 Replies View RelatedPlease let me know what configuration need to be made so that root user
will not be able to log in via gui.
I am aware that taking out tty? from /etc/securetty would result in root not able to log in via CLI modes.
Similarly what is the configuration needed to make that work in GUI.?
I was reading /usr/share/kde4/config/kdm/kdmrc and see this 3 lines:
# Allow root logins?
# Default is false
#AllowRootLogin=false
this doesn't mean that root can't login in a graphical mode? (I can login as root)

Is there a non-root shell command that can tell me if a user's account is disabled or not? note that there is a fine distinction between LOCKING and DISABLED:
LOCKING is where you prepend ! or * or !! to the password field of the /etc/passwd file. On Linux systems that shadow the passwords, this marker flag may be placed in /etc/shadow instead of /etc/passwd. Password locking can be done (at a shell prompt) via password -l username (as root) to lock the account of username, and the use of the option -u will unlock it.
DISABLING an account is done by setting the expiration time of the user account to some point in the past. This can be done with chage -E 0 username, which sets the expiration date to 0 days after the Unix epoch. Setting it to -1 will disable the use of the expiration date.
The effect of locking to to prevent the login process from using a supplied password to hash correctly against the saved hash (by virtue of the fact that the pre-pended marker character(s) are not valid output character(s) for the hash, thus no possible input can ever be used to generate a hash that would match it). The effect of disabling is to prevent any process from using an account because the expiration date of the account has already passed.For my situation, the use of locking is not sufficient because a user might still be able to login, e.g. using ssh authentication tokens, and processes under that user can still spawn other processes. Thus, we have accounts that are enabled or disabled, not just locked. We already know how to disable and enable the account - it requires root access and the use of chage, as shown above.To repeat my question: is there a shell command which can be run without root privileges which can output the status of this account expiration info for a given user? this is intended for use on a Red Hat Enterprise 5.4 system.The output is being returned to a java process which can then parse the output as needed, or make use of the return code.
