NAME
pam_ftp − PAM module for anonymous access
module
SYNOPSIS
|
pam_ftp.so [debug] [ignore] [users=XXX,YYY,...] |
DESCRIPTION
pam_ftp is a PAM module which provides a pluggable anonymous ftp mode of access.
This module intercepts the user´s name and password. If the name is ftp or anonymous, the user´s password is broken up at the @ delimiter into a PAM_RUSER and a PAM_RHOST part; these pam−items being set accordingly. The username (PAM_USER) is set to ftp. In this case the module succeeds. Alternatively, the module sets the PAM_AUTHTOK item with the entered password and fails.
This module is not safe and easily spoofable.
OPTIONS
debug
Print debug information.
ignore
Pay no attention to the email address of the user (if supplied).
ftp=XXX,YYY,...
Instead of ftp or anonymous, provide anonymous login to the comma separated list of users: XXX,YYY,.... Should the applicant enter one of these usernames the returned username is set to the first in the list: XXX.
MODULE TYPES
PROVIDED

EXAMPLES
Add the following line to /etc/pam.d/ftpd to handle ftp
style anonymous login:
#
# ftpd; add ftp−specifics. These lines enable
anonymous ftp over
# standard UN*X access (the listfile entry blocks access to
# users listed in /etc/ftpusers)
#
auth sufficient pam_ftp.so
auth required pam_unix.so use_first_pass
auth required pam_listfile.so \
