ftpusers - list of users that may not log in via the FTP daemon
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.
The format of ftpusers is very simple. There is one account name (or
username) per line. Lines starting with a # are ignored.
/etc/ftpusers
passwd(5), proftpd(8), wuftpd(8)
