FTPUSERS(5)                Linux Programmer's Manual               FTPUSERS(5)
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 also for improv-
       ing security within a TCP/IP networked environment.
       The ftpusers file 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
       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
       username) per line.  Lines starting with a # are ignored.
FILES
       /etc/ftpusers
