FTPUSERS(5)                Linux Programmer's Manual               FTPUSERS(5)



NAME
       ftpusers - list of users(1,5) that may not log in(1,8) via the FTP daemon

DESCRIPTION
       The  text  file(1,n)  ftpusers  contains a list of users(1,5) that may not log in(1,8)
       using the File Transfer Protocol (FTP) server daemon. This file(1,n) is used
       not  merely  for system administration purposes but for improving secu-
       rity within a TCP/IP networked environment. It will typically contain a
       list  of  the  users(1,5) that either have no business using ftp or have too
       many privileges to be allowed to log in(1,8) through the FTP server  daemon.
       Such  users(1,5) usually include root, daemon, bin, uucp, and news.  If your
       FTP server daemon doesn't use ftpusers then it is  suggested  that  you
       read(2,n,1 builtins)  its  documentation  to  find  out how to block access(2,5) for certain
       users. Washington University FTP server  Daemon  (wuftpd)  and  Profes-
       sional 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.

FILES
       /etc/ftpusers

SEE ALSO
       passwd(1,5)(5), proftpd(8), wuftpd(8)
