<H2>DESCRIPTION</H2>
|
|
|
|
The file
|
|
<I>/etc/securetty</I>
|
|
|
|
contains the names of terminals
|
|
(one per line, without leading
|
|
<I>/dev/</I>)
|
|
|
|
which are considered secure for the transmission of certain authentication
|
|
tokens.
|
|
<P>
|
|
|
|
It is used by (some versions of)
|
|
<B><A HREF="/cgi-bin/man/man2html?1+login">login</A></B>(1)
|
|
|
|
to restrict the terminals
|
|
on which root is allowed to login.
|
|
See
|
|
<B><A HREF="/cgi-bin/man/man2html?5+login.defs">login.defs</A></B>(5)
|
|
|
|
if you use the shadow suite.
|
|
<P>
|
|
|
|
On PAM enabled systems, it is used for the same purpose by
|
|
<B><A HREF="/cgi-bin/man/man2html?8+pam_securetty">pam_securetty</A></B>(8)
|
|
|
|
to restrict the terminals on which empty passwords are accepted.
