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
Only the auth module type is provided.
Return Values
- PAM_SUCCESS
The authentication was successful.
- PAM_USER_UNKNOWN
User not known.
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)
