Thank you. It is realy hard to understand, but I think I essentially know it. It seems the relationships among standard streams, terminals, TTYs, clients and servers are actually complicated.

SECURETTY(5)						     Linux Programmer's Manual						      SECURETTY(5)

NAME

       securetty - file which lists terminals from which root can log in

DESCRIPTION

       The file /etc/securetty contains the names of terminals (one per line, without leading /dev/) which are considered secure for the transmis-
       sion of certain authentication tokens.

       It is used by (some versions of) login(1) to restrict the terminals on which root is allowed to login.  See login.defs(5) if  you  use  the
       shadow suite.

       On  PAM	enabled  systems,  it  is  used  for  the  same purpose by pam_securetty(8) to restrict the terminals on which empty passwords are
       accepted.

FILES

       /etc/securetty

SEE ALSO

       login(1), login.defs(5), pam_securetty(8)
