ftpusers - list of users that may not log in via the FTP daemon
The text file ftpusers contains a list of users that may not log in using the File Trans-
fer Protocol (FTP) server daemon. This file is used not merely for system administration
purposes but for improving security within a TCP/IP networked environment. It will typi-
cally 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 Professional FTP Dae-
mon (proftpd) are known to make use of ftpusers.
The format of ftpusers is very simple. There is one account name (or username) per line.
Lines starting with a # are ignored.
passwd(5), proftpd(8), wuftpd(8)
