Special Forums Cybersecurity One accout for FTP other to TELNET Post 23753 by Perderabo on Friday 28th of June 2002 10:18:00 AM

Don't open three threads to ask the same question. I deleted the other threads.

To create an account that can be used only for ftp, I would make the shell "/usr/bin/true". Yeah, you can still telnet in, but you can't do anything and you will disconnect immediately. For such a user to be able to use ftp, "/usr/bin/true" must be added to the file "/etc/shells".

To create an account that can be used by telnet, but not ftp, give this user a regular shell like ksh. Then add it to the file /etc/ftpd/ftpusers. This file, which is badly named, is a list of users who cannot use ftp.

And sure, both users can be in the same group if you want.

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
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) # 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 SEE ALSO
