ftpusers

/etc/ftpusers is used by proftpd(8); the file contains a list of users who are not allowed to use the ftp command. For security reasons at least users like ``root'', ``bin'', ``uucp'' and ``news'' should be listed in this file. Blank lines and lines beginning with `#' are ignored.

Note: a lines with `#' in the middle is not a comment. Don't put `#' after a name to comment it; use another line, or things will silently fail on you.

/etc/ftpusers might contain the following entries:

#
# /etc/ftpusers
#
root
bin
uucp
