<H2>DESCRIPTION</H2>
|
|
|
|
<P>
|
|
|
|
<DD>pam_ftp is a PAM module which provides a pluggable anonymous ftp mode of access.
|
|
<P>
|
|
|
|
This module intercepts the user's name and password. If the name is
|
|
<I>ftp</I>
|
|
or
|
|
<I>anonymous</I>, the user's password is broken up at the
|
|
<I>@</I>
|
|
delimiter into a
|
|
<I>PAM_RUSER</I>
|
|
and a
|
|
<I>PAM_RHOST</I>
|
|
part; these pam-items being set accordingly. The username (<I>PAM_USER</I>) is set to
|
|
<I>ftp</I>. In this case the module succeeds. Alternatively, the module sets the
|
|
<I>PAM_AUTHTOK</I>
|
|
item with the entered password and fails.
|
|
<P>
|
|
|
|
This module is not safe and easily spoofable.
