pam_ftp - PAM module for anonymous access module
2. SYNOPSIS ▲
pam_ftp.so [debug] [ignore] [users=XXX,YYY,...]
3. 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.
4. OPTIONS ▲
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: \fBXXX,YYY,...\fR. Should the applicant enter one of these usernames the returned username is set to the first in the list: XXX.
5. MODULE TYPES PROVIDED ▲
Only the auth module type is provided.
6. RETURN VALUES ▲
The authentication was successful.
User not known.
7. 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)
