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
       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 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 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 mod‐
       ify the security policy in /etc/default/login to reflect the site secu‐
       rity 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 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.
