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