NAME         top

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

DESCRIPTION         top

       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
       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 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.
