NAME
      ftpusers - file listing users to  be  disallowed  ftp  login
      privileges
 


SYNOPSIS
      /etc/ftpusers
 


DESCRIPTION
      The /etc/ftpusers  is an ASCII file  that  lists  users  for
      whom ftp login privileges are disallowed. Each ftpuser entry
      is a single line of the form:
 
 
      name
 
      where name is the user's login name.
 
      The ftp server, in.ftpd(1M), reads the ftpusers file. If the
      login name of the user matches one of the entries listed, it
      rejects the login session and sends  the Login incorrect and
      Login failed error messages.
 
      The ftpusers file has the  following  default  configuration
      entries:
 
 
      root
      daemon
      bin
      sys
      adm
      lp
      uccp
      nuucp
      listen
      nobody
      noaccess
      nobody4
 
      These entries match the default  instantiated  entries  from
      passwd(4).  The  list  of default entries typically contains
      the superuser  root  and  other  administrative  and  system
      application identities.
 
      The root entry is included in /etc/ftpusers  as  a  security
      measure  since  the  default  policy  is  to disallow remote
      logins for this identity. This policy is also set in the the
      default value of the CONSOLE entry in the /etc/default/login"
      file.  See login(1). If you allow root login  privileges  by
      deleting  the  root  entry in /etc/ftpusers, you should also
      should modify the security policy in  /etc/default/login  to
      reflect  the site security policy for remote login access by

      root.
 
      Other default entries are administrative identities that are
      typically  assumed by system applications but never used for
      local or remote login, for example  sys  and  nobody.  Since
      these  entries  do  not  have a valid password field instan-
      tiated in shadow(4), no login can be performed.
 
      If a site adds similar administrative or system  application
      identities  in  passwd(4) and shadow(4), for example, major-
      domo,  the  site   should   consider   including   them   in
      /etc/ftpusers for a consistent security policy.
