COMMAND

    /dev/zero

SYSTEMS AFFECTED

    SunOS (from Sparc1 to Sparc10)

PROBLEM

    Walter  Hafner  posted  about   following  "/dev"  problem.    Try
    following:

        cat /dev/zero > /dev/keyboard

    No special rights required.   Anything from a Sparc1 to  a Sparc10
    under SunOS is dead.

SOLUTION

    These sorts of things are easily taken care of with /etc/fbtab  on
    SunOS4  and  /etc/logindevperm  on  Solaris2.   Any   framebuffer,
    keyboard, mouse, audio  device, etc should  have an entry  here to
    prevent these sorts of pranks.

    In your  /etc/fbtab make  sure you  have the  keyboard set to 0600
    permission under the line:

    # Uncomment the following entries to enable window system security
    /dev/console    0600    /dev/kbd:/dev/mouse
