FTPUSERS(5) Linux Programmer's Manual FTPUSERS(5)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 username) per line. Lines starting with a # are ignored.
FILES
/etc/ftpusers
