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

SYNOPSIS
       /etc/ftpd/ftpusers

DESCRIPTION
       The  ftpusers  file 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 attempt.

       The ftpusers file has the following default configuration entries:

	 root
	 daemon
	 bin
	 sys
	 adm
	 lp
	 uccp
	 nuucp
	 smmsp
	 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 applica-
       tion identities.

       The  root  entry  is included in the ftpusers file as a security measure since the default
       policy is to disallow remote logins for this identity. This policy  is  also  set  in  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 ftpusers, you should also 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 instantiated 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, majordomo, the site should consider including them in the ftpusers
       file for a consistent security policy.

       Lines that begin with # are treated as comment lines and are ignored.
