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 adminis
tration purposes but for improving security 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 priviledges 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 dae
mon 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 Professional 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.
