NAME

6       ftpusers - list of users that may not log in via the FTP daemon
7

DESCRIPTION

9       The  text  file  ftpusers  contains a list of users that may not log in
10       using the File Transfer Protocol (FTP) server  daemon.   This  file  is
11       used not merely for system administration purposes but also for improvā€
12       ing security within a TCP/IP networked environment.
13
14       The ftpusers file will typically contain  a  list  of  the  users  that
15       either  have  no  business  using ftp or have too many privileges to be
16       allowed to log in through the FTP server daemon.   Such  users  usually
17       include root, daemon, bin, uucp, and news.
18
19       If  your  FTP  server daemon doesn't use ftpusers, then it is suggested
20       that you read its documentation to find out how  to  block  access  for
21       certain  users.   Washington  University FTP server Daemon (wuftpd) and
22       Professional FTP Daemon (proftpd) are known to make use of ftpusers.
23
24   Format
25       The format of ftpusers is very simple.  There is one account  name  (or
26       username) per line.  Lines starting with a # are ignored.
