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	disal-
       lowed. 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 at-
       tempt.

       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 application 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 iden-
       tity. 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	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 lo-
       gin, for	example	sys and	nobody.	Since these  entries  do  not  have  a
       valid  password	field  instantiated in shadow(4), no login can be per-
       formed.

       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.
