FTPUSERS(5) Linux Programmer's Manual FTPUSERS(5)
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 also for
improving security within a TCP/IP networked environment.
The ftpusers file 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
username) per line. Lines starting with a # are ignored.
/etc/ftpusers
passwd(5), proftpd(8), wuftpd(8)
