NAME
ftpusers - list of users that may not log in via the FTP daemon
DESCRIPTION
The text file ftpusers contains a list of users that may not log in
using the File Transfer Protocol (FTP) server daemon. This file is used
not merely for system administration purposes but for improving secu-
rity within a TCP/IP networked environment. It will typically contain a
list of the users that either have no business using ftp or have too
many privileges to be allowed to log in through the FTP server daemon.
Such users usually include root, daemon, bin, uucp, and news. If your
FTP server daemon doesn't use ftpusers then it is suggested that you
read its documentation to find out how to block access for certain
users. Washington University FTP server Daemon (wuftpd) and Profes-
sional FTP Daemon (proftpd) are known to make use of ftpusers.
FORMAT
The format of ftpusers is very simple. There is one account name (or
user name) per line. Lines starting with a # are ignored.
