LEARN ABOUT NETBSD
ftpusers
FTPUSERS(5) BSD File Formats Manual FTPUSERS(5)NAME
ftpusers, ftpchroot --ftpd(8) access control file
DESCRIPTION
The ftpusers file provides user access control for ftpd(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 /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.
/etc/ftpchroot
The file /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.
FILES
/etc/ftpchroot List of normal users who should have their ftp session's root directory changed by using chroot(2).
