pam_securetty -- Limit root login to special devices
     __________________________________________________________________

DESCRIPTION

   pam_securetty is a PAM module that allows root logins only if the user
   is logging in on a "secure" tty, as defined by the listing in the
   securetty file. pam_securetty checks at first, if /etc/securetty
   exists. If not and it was built with vendordir support, it will use
   %vendordir%/securetty. pam_securetty also checks that the securetty
   files are plain files and not world writable. It will also allow root
   logins on the tty specified with console= switch on the kernel command
   line and on ttys from the /sys/class/tty/console/active.

   This module has no effect on non-root users and requires that the
   application fills in the PAM_TTY item correctly.

   For canonical usage, should be listed as a required authentication
   method before any sufficient authentication methods.
