FTPUSERS(5) Linux Programmer's Manual FTPUSERS(5)NAMEftpusers - 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 con‐
tain 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 dae‐
mon. 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 Profes‐
sional 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.
