The
file provides user access control for
ftpd(8)
by defining which users may login.
If the
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_pton3)
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.conf5.
If
class
is not given, it defaults to one of the following:
chroot
If there is a match in
Sx /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.conf5
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
,
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).
