pam_ftp is a PAM module which provides a pluggable anonymous ftp mode
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.
Print debug information.
Pay no attention to the email address of the user (if supplied).
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.
Add the following line to /etc/pam.d/ftpd to handle ftp style
# 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 \
onerr=succeed item=user sense=deny file=/etc/ftpusers
