    MBR protection

    Has anybody had problems install Linux over winders with MBR protection?

    I think you can turn it off in the bios.

    New hard drive solves the problem

    Wildheart, we just installed a new HD but I would like to know if MBR protection would bork a Linux (Ubuntu) install.

    Ya it will stop you from writing your boot loader. turn it off for the install.

    Thnx Wildheart

    We were sure that was the problem. If we need that drive later, I will remember the MBR/BIOS solution!!!!!

    Next problem, Full time root privilege in Ubuntu, need to change/move stuff and it won't let me!

    open up a root terminal and use the "mv" and "cp" commands

    like mv /mnt/dir/file.file /dir/to/move/to
    or cp /mnt/dir/file.file /dir/to/copy/to

    or type "passwd root" in root terminal and set a root password.
    then go to System-administration-login screen setup then there's a setting in here to let root log in to Gnome. Then you Could move the stuff with a gui.

    Fatal,

    there is a way to add your user to the "wheel" group and then in one of the files, you can specify whether or not this user is allowed to be a superuser based on the groups (IE: if I'm a member of wheel then I have root privileges via sudo)

    Let me see if I can find it.

    Fatal,

    as root type: visudo
    and hit enter

    Look for a line that looks like:
    Code:
    # Same thing without a password
    # %wheel        ALL=(ALL)       NOPASSWD: ALL
    UNCOMMENT the %wheel line (remove the #)

    Exit and save (should be the escape key, then a :x)

    Now you need to add yourself to the wheel group.

    Code:
    usermod -g wheel USERNAME
    ie: usermod -g wheel FatalError

    That should do the trick

    You should now be able to run anything root can run as your normal user by typing sudo infront of it.

    Cool, way cool

    Rootise, That was a nifty fix.

    I found another that adds a root login at the login screen. Ubuntu hides this feature from the non-geeks like me. Well you can guess what would happen if
    us mere mortals were to get into the "works".

    I am either going to start living on 3rd shift or you have to stop sleeping!

    I am starting to do the Apache, PHP, MySQL thing in preparation for Moodle.
    Living on the line, command line that is! w00t

    And I owe it all to the f00.

    heh, let me know if you need any help with that.

    I could do it in my sleep and I have some suggestions on how it should be done now. (especially when you compile apache and php).
