NAME

DESCRIPTION

If the ftpusers file does not exist, all users are denied access.

A “\” is the escape character; it can be used to escape the meaning of the comment character, or if it is the last character on a line, extends a configuration directive across multiple lines. A “#” is the comment character, and all characters from it to the end of line are ignored (unless it is escaped with the escape character).

The syntax of each line is:

userglob[:groupglob][@host] [directive [class]]

These elements are:

userglob

matched against the user name, using fnmatch(3) glob matching (e.g, ‘f*').

groupglob

matched against all the groups that the user is a member of, using fnmatch(3) glob matching (e.g, ‘*src').

host

either a CIDR address (refer to inet_net_pton(3)) to match against the remote address (e.g, ‘1.2.3.4/24'), or an fnmatch(3) glob to match against the remote hostname (e.g, ‘*.NetBSD.org').

directive

If “allow” or “yes” the user is allowed access. If “deny” or “no”, or directive is not given, the user is denied access.

class

defines the class to use in ftpd.conf(5).

If class is not given, it defaults to one of the following:

chroot

If there is a match in /etc/ftpchroot for the user.

guest

If the user name is “anonymous” or ‘ftp'.

real

If neither of the above is true.

No further comparisons are attempted after the first successful match. If no match is found, the user is granted access. This syntax is backward-compatible with the old syntax.

If a user requests a guest login, the ftpd(8) server checks to see that both “anonymous” and “ftp” have access, so if you deny all users by default, you will need to add both “anonymous allow” and “ftp allow” to /etc/ftpusers in order to allow guest logins.
