View 2 Replies View RelatedUbuntu :: Grub Trouble_Unable To Input Password?
Jul 25, 2011I know there is a similar thread but my problem is different from the other one I read.In the other thread, the grub terminal would not accept the password the person would enterIn my case it literally wont let me type my password or anything at all! It asks me to input my password but no matter how many times I press a key nothing happens.Possibly important details: I am following a guide to change the boot order on grub while running the Ubuntu OS and using the terminal. But the issue is the same, I have tried accessing the root mode but it would not let me type my password there either.

Sep 27, 2009I have just installed Fedora 11 64bit on a new hard disk, using Intel 975BX2 motherbord, 3Gbyte RAM, 320Gbyte hard disk etc., USB mouse and keyboard. The installation went fine, but when I enter the password for the boot (I assume GRUB was installed) it fails to recognise the password. Do this three times and the boot segment ??? fails to initialise.
I recall a linux magazine i buy indicating that you have to copy and paste the password manually after installation, but i cannot recall the article date. Is this a problem - the password protection for the GRUB boot loader does not work at installation time when using the graphical interface ?. I did not use any odd characters - basic letters and numbers.
OpenSUSE Install :: Password On The Grub Bootloader On 11.2 Box?
May 23, 2011I'm trying to install a password on the Grub bootloader on my 11.2 box. I ran yast2 bootloader then clicked on bootloader options, then the checkbox for using a password, and then typed in my password twice. It isn't working. I've tried various different passwords to see if something was throwing it off like special characters or too many characters but no matter what I do I can't use the password to unlock the bootloader on bootup. It just tells me that I entered the incorrect password.

Jul 29, 2009I am new to Fedora. I know my top probably already been posted somewhere but I just could not find it. I just installed Fedora 11. But my root password does not work (I guess was my fault to type wrong in the first place or some type of short term memory lost). I looked at the root password recovery procedure which involves select single user at GRUB page when booting. But for some reasons, Fedora 11 does not boot into GRUB. I tried Alt+CTRL+F1, F1 or Shift, none of those gives me Grub screen.

View 1 Replies View RelatedDebian Installation :: Squeeze - Change Grub Password And Console Font Size?
Nov 5, 2010I'm trying to do is protect the computer against housemates. The standard procedure I do with Lenny:
1. Password protect BIOS.
2. In BIOS, always boot from hard drive. Disable booting from any other device such as USB or CD-ROM.
3. Password protect Grub (v1) using the "password --md5 $1$9MuaA/$5TDLgvmcEiCWNr5W9VaMK1" syntax in my menu.lst file.
With the above precautions in place, [I think] the only way to gain root access to the system is to take the case lid off and proceed to do stuff physically (like set jumpers and/or take out the hard drive). Am I correct? My reasoning for this is, the computer boots -> must boot from HD -> must load Grub -> must go to default menu item since others are protected, and cannot command prompt in Grub without password.
Anyhow, In Squeeze, I was a bit disappointed to find out, after doing a bit of Google-research, that Grub v2 (which is standard on Squeeze now) does not easily support password protecting the Grub menu. Am I correct? Will this issue perhaps be addressed in the Squeeze final release? Is this feature dumb anyways because the Grub password is of no use (i.e. my paragraph above is complete horseradish)?
Another thing I would like to do is change the console font and size back to something more "normal" or "classic", not some crazy tiny font that's only found in totally bleeding edge Linux distrubutions <gasp!>. I found that the Squeeze console font (e.g. when I type Ctrl+Alt+F1) is wicked tiny. I wanna change it to "normal". Grub v2 password and console font config?
Fedora Security :: Reset The Root Password By Booting Into Single Usermode By Editing Grub
Apr 17, 2009Being able to reset the root password by booting into single usermode by editing grub. This is a MAJOR flaw. I know it makes no real difference against internet bourne attacks, but even so I must say I found it shocking. The only way I've found to stop this is to encrypt the entire HDD, so noone could get into single user mode without first knowing the encryption key/password.

View 9 Replies View RelatedUbuntu :: GRUB 2 : Difference Between 'grub-pc', 'grub-efi' And 'grub-coreboot'?
Jan 6, 2010I would like to know if there is any differences on how to install and to configure GRUB 2 in the different architectures (BIOS/IBM PC-Compatibles, EFI/MacIntel and Corebbot)? Does the Ubuntu installer automatically recognize the different architectures and install the appropriate GRUB 2 package ('grub-pc', 'grub-efi' or 'grub-coreboot' according to the arch)? Or does it just install 'grub-pc'? Is the location of GRUB 2's configuration files different depending on the arch of the computer? Or are they all located in '/boot/grub/', '/etc/grub/default' and '/etc/grub.d/', no matter the arch of the computer? Are the files' structure and options to configure GRUB 2 ('/etc/grub/default' and the scripts in '/etc/grub.d/') different depending on the arch of the computer?

Jan 3, 2010I'm just slightly confused here, but... what the? Why does installing grub-doc remove BOTH grub-pc, and grub-common? So basically it seems like by installing grub-doc, I have uninstalled grub totally (yes, it is still there as the bootloader, but i have no way of updating it now!) from my system. What's the conflict between grub-doc and grub-pc, such that grub-pc has to be removed?

View 4 Replies View RelatedUbuntu :: Change Root Password - Typing A Password, No Characters Show Up?
Mar 9, 2010I'm really new to Linux so this will probably sound like a pretty naive question to most users, but how do you change the root password?To install Java, I have to type # su into Terminal,which then asks for the password.What's weird is that when I start typing a password, no characters show up. I don't know if this is supposed to happen or not.I've found a bunch of different sites on the Internet that explain how to change the root password, but none of them seem to work for my specific work station.
I've got Ubuntu 9.10 64 bit. In the GRUB boot menu, I can choose to boot normal or in recovery mode (I'm led to believe older versions don't have this option).I've tried typing # sudo passwrd into Terminal, but I already have a root password set up apparently, so I can't change it there.

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?

Ubuntu :: No Administrator Password - VLC Install Blocked By Password Prompt

View 5 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?
