NAME
ftpusers, ftpchroot -- tnftpd(8) access control file DESCRIPTION
The ftpusers file provides user access control for tnftpd(8) by defining which users may login. 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 /private/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 tnftpd(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 /private/etc/ftpusers in order to allow guest logins. /private/etc/ftpchroot The file /private/etc/ftpchroot is used to determine which users will have their session's root directory changed (using chroot(2)), either to the directory specified in the ftpd.conf(5) chroot directive (if set), or to the home directory of the user. If the file does not exist, the root directory change is not performed. The syntax is similar to ftpusers, except that the class argument is ignored. If there's a positive match, the session's root directory is changed. No further comparisons are attempted after the first successful match. This syntax is backward-compatible with the old syntax.

NAME
ftphosts - FTP Server individual user host access file SYNOPSIS
/etc/ftpd/ftphosts DESCRIPTION
The ftphosts file is used to allow or deny access to accounts from specified hosts. The following access capabilities are supported: allow username addrglob [addrglob...] Only allow users to login as username from host(s) that match addrglob. deny username addrglob [addrglob...] Do not allow users to login as username from host(s) that match addrglob. A username of * matches all users. A username of anonymous or ftp specifies the anonymous user. addrglob is a regular expression that is matched against hostnames or IP addresses. addrglob may also be in the form address:netmask or address/CIDR, or be the name of a file that starts with a slash ('/') and contains additional address globs. An exclamation mark (`!') placed before the addrglob negates the test. The first allow or deny entry in the ftphosts file that matches a username and host is used. If no entry exists for a username, then access is allowed. Otherwise, a matching allow entry is required to permit access. EXAMPLES
You can use the following ftphosts file to allow anonymous access from any host except those on the class A network 10, with the exception of 10.0.0.* IP addresses, which are allowed access: allow ftp 10.0.0.* deny ftp 10.*.*.* allow ftp * 10.0.0.* can be written as 10.0.0.0:255.255.255.0 or 10.0.0.0/24.
