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.
