9 The text file ftpusers contains a list of users that may not log in us‐
10 ing the File Transfer Protocol (FTP) server daemon. This file is used
11 not merely for system administration purposes but also for improving
12 security within a TCP/IP networked environment.

14 The ftpusers file will typically contain a list of the users that ei‐
15 ther have no business using ftp or have too many privileges to be al‐
16 lowed to log in through the FTP server daemon. Such users usually in‐
17 clude root, daemon, bin, uucp, and news.

19 If your FTP server daemon doesn't use ftpusers, then it is suggested
20 that you read its documentation to find out how to block access for
21 certain users. Washington University FTP server Daemon (wuftpd) and
22 Professional FTP Daemon (proftpd) are known to make use of ftpusers.
