Wed May 9 02:04:08 UTC 2001 lukem
* released 1.1
Sat Apr 28 07:13:57 UTC 2001 lukem
* released 1.1 beta 1
* determine if crypt() and getusershell() need declarations
Wed Apr 25 06:27:08 UTC 2001 lukem
* update to NetBSD-current 2001/04/25:
- update copyrights
- remove superfluous byte_count update in send_file_list
- use own code instead of bothering with glob() to do ~
expansion in pathname; there's no need to support glob
wildcards in this case when it's not expanded here in the
non-~ case
- As threatened, handle OOB commands from within ftpcmd.y.
This involved changing the yacc syntax to be line-oriented,
rather than having it run against the entire input at once,
and adding a flag to struct tab, to indicate if or not
it's acceptable for a command to occur OOB.
Tue Apr 17 08:20:09 UTC 2001 lukem
* look for <arpa/nameser.h>
* pull in <arpa/nameser.h> for INADDRZ, IN6ADDRSZ and INT16SZ,
and define if missing
* don't bother trying to use if_indextoname() in ip6_sa2str()
(fixes problems on MacOS X)
* remove unused sverrno in warnx() and errx()
Fri Apr 13 16:02:40 UTC 2001 lukem
* improve test for long long support so that it's only enabled
if printf supports %ll or %q and they do the right thing.
use %q instead of %ll #if HAVE_PRINTF_QD
* added NEWS file
* support S/Key with add support for --with-skey
* pull up changes made in NetBSD in ftpcmd.y revision 1.61:
make checkportcmd address family independent, and correct
IPv4 case. PR 12558.
Sun Apr 8 03:35:55 UTC 2001 lukem
* release 1.0
Thu Apr 5 14:08:25 UTC 2001 lukem
* search for lockf and flock, and use the first found (in that
order) to lock the pid files
* pull up fix to glob.c from rev 1.21 of NetBSD's __glob13.c:
- Fix sentinel for the buffer in globtilde. It was off
by x 2. Noted by Theo.
Thu Mar 29 16:57:17 EST 2001 lukem
* release 1.0 beta 4
* merge ftpd from NetBSD-current (20010329):
- don't leak globbed memory.
* only look for setproctitle in -lutil if fparseln wasn't found in it
* only REPLACE_FUNC(fparseln) if it wasn't found in -lutil
* always compile in local glob; it's the best way to ensure that
various security issues are fixed
* update glob(3) to netbsd-current (20010329), adding support for
GLOB_LIMIT and fixing various buffer overflows.
* support --enable-builtinls (default) and --disable-builtinls
Sun Mar 18 10:14:17 UTC 2001 lukem
* detect if d_namlen exists in struct dirent, and use in
fts_open() appropriately
Sun Mar 18 08:30:01 UTC 2001 lukem
* released 1.0 beta3
* use inbuilt ls source
* autoconf improvements:
- replace missing fts_open, strmode, user_from_uid
- detect if optreset exists, and only use if it does
- fix AC_MSG strings (remove comma's from the messages)
* fixes to inbuilt ls:
- revert part of previous
- add rcsid
- remove stat_flags; flags_to_string is unused (i.e, ignore -o)
- conditionally support S_IFWHT
- hardcode blocksize to 1K
- remove support for nsec comparison in time sorting
Sat Mar 17 12:02:51 UTC 2001 lukem
* generate cat manpages
* merge ftpd from NetBSD-current (20010317):
- make sure we do not return stray " at the end of stirng,
like bla"\0. From: "William C. Allen" <allenwc@home.com>
- ensure replydirname() do not truncate the names.
From: Paul Janzen <pjanzen@foatdi.harvard.edu>
- don't support t(erabyte) as a suffix in strsuftoll()

initialized and could contain trash.
- fix redundant declarations.
- comment or delete text after CPP directives.
- consistently use syslog priorities
* improve detection of working glob(), including requiring GLOB_LIMIT.
don't bother explicilty looking for glob.h; the test above will
detect that.
* update replacement glob() to support GLOB_LIMIT
* look for setproctitle in -lutil as well
* pull in <paths.h> if it exists, but still check each _PATH_xxx and

INSTALLATION INTRODUCTION
-------------------------
This file describes how to compile and install lukemftpd on your
system.
============================================
= =
= NOTE: You will need an ANSI C compiler. =
= =
============================================
For most systems, execute the following to compile and install
lukemftpd:
./configure
make
make install
Preformatted manual pages for ftpd(8), ftpd.conf(5), and ftpusers(5) are
also installed. If you wish to install the sources, ensure that your system
has up-to-date mandoc macros. groff ships with this macro suite,
but it has bugs. Try:
ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-current/src/share/tmac/
for a more recent version.
CONFIGURATION OPTIONS
---------------------
lukemftpd is configured using an `autoconf' generated `configure'
script. `configure' supports the following options:
* The standard `autoconf configure' options, including:
--prefix=PREFIX install architecture-independent files in PREFIX
[/usr/local]
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[same as prefix]
--srcdir=DIR find the sources in DIR [configure dir or ..]
BSD or GNU make may be required for this to work.
* Specific options:
--enable-ipv6 Enable IPv6 support (if your OS supports it)
--disable-ipv6 Disable IPv6 support (even if your OS supports it.)
[default: enabled].
--with-socks Compile with SOCKS firewall traversal support.
--with-socks5[=PATH] Compile with SOCKS5 firewall traversal support.
--with-socks4[=PATH] Compile with SOCKS4 firewall traversal support.
--with-skey Compile with S/Key authentication support.
The following environment variables can be set to override various
compiler related settings.
CC=compiler specify name of the C compiler (default: gcc or cc)
CFLAGS=flags specify flags to C compiler (default: -O -g or just -O)
LDFLAGS=flags specify flags to linker (default: none)
This can be achieved with:
env CC="compiler" CFLAGS="flags" LDFLAGS="flags" ./configure
============================================

============================================
PLATFORM SPECIFIC NOTES
-----------------------
The following platforms & compilers have been tested:
- Irix 6.5
- Compiler: /usr/local/bin/gcc
version: egcs-1.1.2
Configure with:
./configure --disable-builtinls
as the in-built ls code doesn't appear to work due to
problems in the fts routines.
- Linux 2.4 kernel with glibc prior to 2.2
Configure with:
./configure --disable-ipv6
as glibc before 2.2 doesn't correctly support sin6_scope_id.
- NetBSD 1.5 (i386)
- Compiler: /usr/bin/cc
version: egcs-1.1.2
- Solaris 2.6 (sparc)
- Compiler: /opt/SUNWspro/bin/cc
version: WorkShop Compilers 5.0
- Tru64 5.0
- Compiler: /bin/cc
version: Compaq C V6.1-011 on Digital UNIX V5.0 (Rev. 910)

WHAT IS LUKEMFTPD?
------------------
`lukemftpd' is what many users affectionately call the enhanced ftp
server in NetBSD (http://www.netbsd.org). The `lukem' comes from
the account name of the NetBSD developer who wrote most of the
enhancements: Luke Mewburn <lukem@netbsd.org>.
This package is a `port' of the NetBSD ftp server to other systems.
The enhancements over the standard ftp server in 4.4BSD (and derivatives)
include:
* command line options:
+ allow override of directory used by anonymous ftp (-a)
+ optional change of directory for configuration files (-c)
+ check whether a user would be granted access (-C)
+ specify email address for display messages (-e)
+ change hostname advertised as (-h, -H)
+ specify data port to listen on (-P)
+ keep track of the number of users logged in (-q, -Q)
+ permanently drop privileges (-r)
+ specify version advertised (-V)
+ log wu-ftpd style `xferlog' entries to syslog (-X)
* % escape sequences in files displayed to users (/etc/motd,
/etc/ftpwelcome, ...)
* IPv6 support (from the KAME project).
* ftpusers(5) control of who may log in, and optional
specification of a "class" to be associated with the
specified user or group.
* ftpd.conf(5) to control various configuration options on
a per-class basis. The following options are supported:
+ address to advertise in PASV and LPSV responses
+ check the PORT command for validity
+ specify the directory to chroot(2) to
+ automatic in-line conversions (e.g, `.tar.gz'
retrieval of directories)
+ display a file the first time a directory is entered
+ specify the home directory of the session (for "cd ~")
+ limit the maximum number of concurrent sessions
+ limit the maximum size of an uploaded file
+ set the default timeout and restrict the maximum
timeout that a user may request
+ deny user from running the CHMOD, DELE, MKD, RMD, RNFR
and UMASK commands
+ specify the motd(5) file to display upon login
+ specify a glob(3) pattern of files to notify a user
of the existance of once a directory is entered
+ enable/disable the use of PASV and EPSV connections
+ limit the ports that PORT and LPRT may bind to
+ limit the transfer rate of transfers
+ limit the characters that may be used in an uploaded
filename
+ set the umask
+ deny user from running APPE, STOR and STOU as well
as CHMOD, ...
* In-built copy of ls(1) to implement LIST (unless disabled
out with --disable-builtinls), so that /bin/ls does not need
to exist inside the ftp tree.
* Virtual servers can be supported with a combination of
ftpd(8) flags and support in the invoking inetd(8) program
(such as that in NetBSD).
* Optional S/Key authentication (if configued with --with-skey).
Features present in NetBSD's ftpd but not yet available in lukemftpd:
* logging active sessions to utmp(5) (-u, -U)
* logging completed sessions to wtmp(5) (-w, -W)

dnl
dnl Written by John Hawkinson <jhawk@mit.edu>. This code is in the Public
dnl Domain.
dnl
dnl This test is for network applications that need socket() and
dnl gethostbyname() -ish functions. Under Solaris, those applications need to
dnl link with "-lsocket -lnsl". Under IRIX, they should *not* link with
dnl "-lsocket" because libsocket.a breaks a number of things (for instance:
dnl gethostbyname() under IRIX 5.2, and snoop sockets under most versions of
dnl IRIX).
dnl
dnl Unfortunately, many application developers are not aware of this, and
dnl mistakenly write tests that cause -lsocket to be used under IRIX. It is
dnl also easy to write tests that cause -lnsl to be used under operating
dnl systems where neither are necessary (or useful), such as SunOS 4.1.4, which
dnl uses -lnsl for TLI.
dnl
dnl This test exists so that every application developer does not test this in
dnl a different, and subtly broken fashion.
dnl
dnl It has been argued that this test should be broken up into two seperate
dnl tests, one for the resolver libraries, and one for the libraries necessary
dnl for using Sockets API. Unfortunately, the two are carefully intertwined and
dnl allowing the autoconf user to use them independantly potentially results in
dnl unfortunate ordering dependancies -- as such, such component macros would
dnl have to carefully use indirection and be aware if the other components were
dnl executed. Since other autoconf macros do not go to this trouble, and almost
dnl no applications use sockets without the resolver, this complexity has not
dnl been implemented.
dnl
dnl The check for libresolv is in case you are attempting to link statically
dnl and happen to have a libresolv.a lying around (and no libnsl.a).
dnl

Internet File Transfer Protocol server
.Sh SYNOPSIS
.Nm
.Op Fl dHlqQrsuUwWX
.Op Fl a Ar anondir
.Op Fl c Ar confdir
.Op Fl C Ar user
.Op Fl e Ar emailaddr
.Op Fl h Ar hostname
.Op Fl P Ar dataport
.Op Fl V Ar version
.Sh DESCRIPTION
.Nm
is the Internet File Transfer Protocol server process.
The server uses the
.Tn TCP
protocol and listens at the port specified in the
.Dq ftp
service specification; see
.Xr services 5 .
.Pp
Available options:
.Bl -tag -width Ds
.It Fl a Ar anondir
Define
.Ar anondir
as the directory to
.Xr chroot 2
into for anonymous logins.
Default is the home directory for the ftp user.
This can also be specified with the
.Xr ftpd.conf 5
.Sy chroot
directive.
.It Fl c Ar confdir
Change the root directory of the configuration files from
.Dq Pa /etc
to
.Ar confdir .
This changes the directory for the following files:
.Pa /etc/ftpchroot ,
.Pa /etc/ftpusers ,
.Pa /etc/ftpwelcome ,
.Pa /etc/motd ,
and the file specified by the
.Xr ftpd.conf 5
.Sy limit
directive.
.It Fl C Ar user
Check whether
.Ar user
would be granted access under
the restrictions given in
.Xr ftpusers 5
and exit without attempting a connection.
.Nm
exits with an exit code of 0 if access would be granted, or 1 otherwise.
This can be useful for testing configurations.
.It Fl d
Debugging information is written to the syslog using a facility of
.Dv LOG_FTP .
.It Fl e Ar emailaddr
Use
.Ar emailaddr
for the
.Dq "\&%E"
escape sequence (see
.Sx Display file escape sequences )
.It Fl h Ar hostname
Explicitly set the hostname to advertise as to
.Ar hostname .
The default is the hostname associated with the IP address that
.Nm
is listening on.
This ability (with or without
.Fl h ) ,
in conjunction with
.Fl c Ar confdir ,
is useful when configuring
.Sq virtual
.Tn FTP
servers, each listening on separate addresses as separate names.
Refer to
.Xr inetd.conf 5
for more information on starting services to listen on specific IP addresses.
.It Fl H
Equivalent to
.Do
-h
`hostname`
.Dc .
.It Fl l
Each successful and failed
.Tn FTP
session is logged using syslog with a facility of
.Dv LOG_FTP .
If this option is specified more than once, the retrieve (get), store (put),
append, delete, make directory, remove directory and rename operations and
their file name arguments are also logged.
.It Fl P Ar dataport
Use
.Ar dataport
as the data port, overriding the default of using the port one less
that the port
.Nm
is listening on.
.It Fl q
Enable the use of pid files for keeping track of the number of logged-in
users per class.
This is the default.
.It Fl Q
Disable the use of pid files for keeping track of the number of logged-in
users per class.
This may reduce the load on heavily loaded
.Tn FTP
servers.
.It Fl r
Permanently drop root privileges once the user is logged in.
The use of this option may result in the server using a port other
than the (listening-port - 1) for
.Sy PORT
style commands, which is contrary to the
.Cm RFC 959
specification, but in practice very few clients rely upon this behaviour.
See
.Sx SECURITY CONSIDERATIONS
below for more details.
.It Fl s
Require a secure authentication mechanism like Kerberos or S/Key to be used.
.It Fl u
Log each concurrent
.Tn FTP
session to
.Pa /var/run/utmp ,
making them visible to commands such as
.Xr who 1 .
.It Fl U
Don't log each concurrent
.Tn FTP
session to
.Pa /var/run/utmp .
This is the default.
.It Fl V Ar version
Use
.Ar version
as the version to advertise in the login banner and in the output of
.Sy STAT
and
.Sy SYST
instead of the default version information.
If
.Ar version
is empty or
.Sq -
then don't display any version information.
.It Fl w
Log each
.Tn FTP
session to
.Pa /var/log/wtmp ,
making them visible to commands such as
.Xr last 1 .
This is the default.
.It Fl W
Don't log each
.Tn FTP
session to
.Pa /var/log/wtmp .
.It Fl X
Log
.Tn wu-ftpd
style
.Sq xferlog
entries to the syslog, prefixed with
.Dq "xferlog:\ " ,
using a facility of
.Dv LOG_FTP .
These syslog entries can be converted to a
.Tn wu-ftpd
style
.Pa xferlog
file suitable for input into a third-party log analysis tool with a command
similar to:
.Dl "grep 'xferlog: ' /var/log/xferlog | \e"
.Dl "\ \ \ sed -e 's/^.*xferlog: //' > wuxferlog"
.El
.Pp
The file
.Pa /etc/nologin
can be used to disable
.Tn FTP
access.
If the file exists,
.Nm
displays it and exits.
If the file
.Pa /etc/ftpwelcome
exists,
.Nm
prints it before issuing the
.Dq ready
message.
If the file
.Pa /etc/motd
exists (under the chroot directory if applicable),
.Nm
prints it after a successful login.
This may be changed with the
.Xr ftpd.conf 5
directive
.Sy motd .
.Pp
The
.Nm
server currently supports the following
.Tn FTP
requests.
The case of the requests is ignored.
.Bl -column "Request" -offset indent
.It Sy Request Ta Sy Description
.It ABOR Ta "abort previous command"
.It ACCT Ta "specify account (ignored)"

.El
.Pp
The following non-standard or
.Ux
specific commands are supported by the SITE request.
.Pp
.Bl -column Request -offset indent
.It Sy Request Ta Sy Description
.It CHMOD Ta "change mode of a file, e.g. ``SITE CHMOD 755 filename''"
.It HELP Ta "give help information."

.El
.Pp
The following
.Tn FTP
requests (as specified in
.Cm RFC 959 )
are recognized, but are not implemented:
.Sy ACCT ,
.Sy SMNT ,
and
.Sy REIN .
.Sy MDTM
and
.Sy SIZE
are not specified in
.Cm RFC 959 ,
but will appear in the
next updated
.Tn FTP
RFC.
.Pp
The
.Nm
server will abort an active file transfer only when the
.Sy ABOR
command is preceded by a Telnet "Interrupt Process" (IP)
signal and a Telnet "Synch" signal in the command Telnet stream,
as described in Internet
.Cm RFC 959 .
If a
.Sy STAT
command is received during a data transfer, preceded by a Telnet IP
and Synch, transfer status will be returned.
.Pp
.Nm
interprets file names according to the
.Dq globbing
conventions used by
.Xr csh 1 .
This allows users to utilize the metacharacters
.Dq Li \&*?[]{}~ .
.Sh User authentication
.Pp
.Nm
authenticates users according to five rules.
.Pp
.Bl -enum -offset indent
.It
The login name must be in the password data base,
.Pa /etc/pwd.db ,
and not have a null password.
In this case a password must be provided by the client before any
file operations may be performed.
If the user has an S/Key key, the response from a successful
.Sy USER
command will include an S/Key challenge.
The client may choose to respond with a
.Sy PASS
command giving either
a standard password or an S/Key one-time password.
The server will automatically determine which type of password it
has been given and attempt to authenticate accordingly.
See
.Xr skey 1
for more information on S/Key authentication.
S/Key is a Trademark of Bellcore.
.It
The login name must be allowed based on the information in
.Xr ftpusers 5 .
.It
The user must have a standard shell returned by
.Xr getusershell 3 .
If the user's shell field in the password database is empty, the
shell is assumed to be
.Pa /bin/sh .
.It
If directed by the file
.Xr ftpchroot 5
the session's root directory will be changed by
.Xr chroot 2
to the directory specified in the
.Xr ftpd.conf 5
.Sy chroot
directive (if set),
or to the home directory of the user.
However, the user must still supply a password.
This feature is intended as a compromise between a fully anonymous account
and a fully privileged account.
The account should also be set up as for an anonymous account.
.It
If the user name is
.Dq anonymous
or
.Dq ftp ,
an
anonymous
.Tn FTP
account must be present in the password
file (user
.Dq ftp ) .
In this case the user is allowed
to log in by specifying any password (by convention an email address for
the user should be used as the password).
.Pp
The server performs a
.Xr chroot 2
to the directory specified in the
.Xr ftpd.conf 5
.Sy chroot
directive (if set),
the
.Fl a Ar anondir
directory (if set),
or to the home directory of the
.Dq ftp
user.
.Pp
The server then performs a
.Xr chdir 2
to the directory specified in the
.Xr ftpd.conf 5
.Sy homedir
directive (if set), otherwise to
.Pa / .
.Pp
If other restrictions are required (such as disabling of certain
commands and the setting of a specific umask), then appropriate
entries in
.Xr ftpd.conf 5
are required.
.Pp
If the first character of the password supplied by an anonymous user
is
.Dq - ,
then the verbose messages displayed at login and upon a
.Sy CWD
command are suppressed.
.El
.Sh Display file escape sequences
.Pp
When
.Nm
displays various files back to the client (such as
.Pa /etc/ftpwelcome
and
.Pa /etc/motd ) ,
various escape strings are replaced with information pertinent
to the current connection.
.Pp
The supported escape strings are:
.Bl -tag -width "Escape" -offset indent -compact
.It Sy "Escape"
.Sy Description
.It "\&%c"
Class name.
.It "\&%C"
Current working directory.
.It "\&%E"
Email address given with
.Fl e .
.It "\&%L"
Local hostname.
.It "\&%M"
Maximum number of users for this class.
Displays
.Dq unlimited
if there's no limit.
.It "\&%N"
Current number of users for this class.
.It "\&%R"
Remote hostname.
.It "\&%s"
If the result of the most recent
.Dq "\&%M"
or
.Dq "\&%N"
was not
.Dq Li 1 ,
print an
.Dq s .
.It "\&%S"
If the result of the most recent
.Dq "\&%M"
or
.Dq "\&%N"
was not
.Dq Li 1 ,
print an
.Dq S .
.It "\&%T"
Current time.
.It "\&%U"
User name.
.It "\&%\&%"
A
.Dq \&%
character.
.El
.Sh Setting up a restricted ftp subtree
.Pp
In order that system security is not breached, it is recommended
that the
subtrees for the
.Dq ftp
and
.Dq chroot
accounts be constructed with care, following these rules
(replace
.Dq ftp
in the following directory names
with the appropriate account name for
.Sq chroot
users):
.Bl -tag -width "~ftp/incoming" -offset indent
.It Pa ~ftp
Make the home directory owned by
.Dq root
and unwritable by anyone.
.It Pa ~ftp/bin
Make this directory owned by
.Dq root
and unwritable by anyone (mode 555).
Generally any conversion commands should be installed
here (mode 111).
.It Pa ~ftp/etc
Make this directory owned by
.Dq root
and unwritable by anyone (mode 555).
The files
.Pa pwd.db
(see
.Xr passwd 5 )
and
.Pa group
(see
.Xr group 5 )
must be present for the
.Sy LIST
command to be able to display owner and group names instead of numbers.
The password field in
.Xr passwd 5
is not used, and should not contain real passwords.
The file
.Pa motd ,
if present, will be printed after a successful login.
These files should be mode 444.
.It Pa ~ftp/pub
This directory and the subdirectories beneath it should be owned
by the users and groups responsible for placing files in them,
and be writable only by them (mode 755 or 775).
They should
.Em not
be owned or writable by ftp or its group.
.It Pa ~ftp/incoming
This directory is where anonymous users place files they upload.
The owners should be the user
.Dq ftp
and an appropriate group.
Members of this group will be the only users with access to these
files after they have been uploaded; these should be people who
know how to deal with them appropriately.
If you wish anonymous
.Tn FTP
users to be able to see the names of the
files in this directory the permissions should be 770, otherwise
they should be 370.
.Pp
The following
.Xr ftpd.conf 5
directives should be used:
.Dl "modify guest off"
.Dl "umask guest 0707"
.Pp
This will result in anonymous users being able to upload files to this
directory, but they will not be able to download them, delete them, or
overwrite them, due to the umask and disabling of the commands mentioned
above.
.It Pa ~ftp/tmp
This directory is used to create temporary files which contain
the error messages generated by a conversion or
.Sy LIST
command.
The owner should be the user
.Dq ftp .
The permissions should be 300.
.Pp
If you don't enable conversion commands, or don't want anonymous users
uploading files here (see
.Pa ~ftp/incoming
above), then don't create this directory.
However, error messages from conversion or
.Sy LIST
commands won't be returned to the user.
(This is the traditional behaviour.)
Note that the
.Xr ftpd.conf 5
directive
.Sy upload
can be used to prevent users uploading here.
.El
.Pp
To set up "ftp-only" accounts that provide only
.Tn FTP ,
but no valid shell
login, you can copy/link
.Pa /sbin/nologin
to
.Pa /sbin/ftplogin ,
and enter
.Pa /sbin/ftplogin
to
.Pa /etc/shells
to allow logging-in via
.Tn FTP
into the accounts, which must have
.Pa /sbin/ftplogin
as login shell.
.Sh FILES
.Bl -tag -width /etc/ftpwelcome -compact
.It Pa /etc/ftpchroot
List of normal users who should be
.Xr chroot 2 ed.

.Sh STANDARDS
.Nm
recognizes all commands in
.Cm RFC 959 ,
follows the guidelines in
.Cm RFC 1123 ,
recognizes all commands in
.Cm RFC 2228
(although they are not supported yet),
and supports the extensions from
.Cm RFC 2389 ,
.Cm RFC 2428
and
.Cm draft-ietf-ftpext-mlst-11 .
.Sh HISTORY
The
.Nm
command appeared in
.Bx 4.2 .
.Pp
Various features such as the
.Xr ftpd.conf 5
functionality,
.Cm RFC 2389 ,
and
.Cm draft-ietf-ftpext-mlst-11
support was implemented in
.Nx 1.3
and later releases by Luke Mewburn <lukem@netbsd.org>.
.Sh BUGS
The server must run as the super-user to create sockets with
privileged port numbers (i.e, those less than
.Dv IPPORT_RESERVED ,
which is 1024).
If
.Nm
is listening on a privileged port
it maintains an effective user id of the logged in user, reverting
to the super-user only when binding addresses to privileged sockets.
The
.Fl r
option can be used to override this behaviour and force privileges to
be permanently revoked; see
.Sx SECURITY CONSIDERATIONS
below for more details.

may have trouble handling connections from scoped IPv6 addresses, or
IPv4 mapped addresses
.Po
IPv4 connection on
.Dv AF_INET6
socket
.Pc .
For the latter case, running two daemons,
one for IPv4 and one for IPv6, will avoid the problem.
.Sh SECURITY CONSIDERATIONS
.Cm RFC 959
provides no restrictions on the
.Sy PORT
command, and this can lead to security problems, as
.Nm
can be fooled into connecting to any service on any host.
With the
.Dq checkportcmd
feature of the
.Xr ftpd.conf 5 ,
.Sy PORT
commands with different host addresses, or TCP ports lower than
.Dv IPPORT_RESERVED
will be rejected.
This also prevents
.Sq third-party proxy ftp
from working.
Use of this option is
.Em strongly
recommended, and enabled by default.
.Pp
By default
.Nm
uses a port that is one less than the port it is listening on to
communicate back to the client for the
.Sy EPRT ,
.Sy LPRT ,
and
.Sy PORT
commands, unless overridden with
.Fl P Ar dataport .
As the default port for
.Nm
(21) is a privileged port below
.Dv IPPORT_RESERVED ,
.Nm
retains the ability to switch back to root privileges to bind these
ports.
In order to increase security by reducing the potential for a bug in
.Nm
providing a remote root compromise,
.Nm
will permanently drop root privileges if one of the following is true:
.Bl -enum -offset indent
.It
.Nm
is running on a port greater than
.Dv IPPORT_RESERVED
and the user has logged in as a
.Sq guest
or
.Sq chroot
user.
.It
.Nm
was invoked with
.Fl r .
.El
.Pp
Don't create
.Pa ~ftp/tmp
if you don't want anonymous users to upload files there.
That directory is only necessary if you want to display the error
messages of conversion commands to the user.
Note that if uploads are disabled with the
.Xr ftpd.conf 5
directive
.Sy upload ,
then this directory cannot be abused by the user in this way, so it
should be safe to create.

.Dt FTPD.CONF 5
.Os
.Sh NAME
.Nm ftpd.conf
.Nd
.Xr ftpd 8
configuration file
.Sh DESCRIPTION
The
.Nm
file specifies various configuration options for
.Xr ftpd 8
that apply once a user has authenticated their connection.
.Pp
.Nm
consists of a series of lines, each of which may contain a
configuration directive, a comment, or a blank line.
Directives that appear later in the file override settings by previous
directives.
This allows
.Sq wildcard
entries to define defaults, and then have class-specific overrides.
.Pp
A directive line has the format:
.Dl command class [arguments]
.Pp
A
.Dq \e
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
.Dq #
is the comment character, and all characters from it to the end of
line are ignored (unless it is escaped with the escape character).
.Pp
Each authenticated user is a member of a
.Em class ,
which is determined by
.Xr ftpusers 5 .
.Em class
is used to determine which
.Nm
entries apply to the user.
The following special classes exist when parsing entries in
.Nm "" :
.Bl -tag -width "chroot" -compact -offset indent
.It Sy all
Matches any class.
.It Sy none
Matches no class.
.El
.Pp
Each class has a type, which may be one of:
.Bl -tag -width "CHROOT" -offset indent
.It Sy GUEST
Guests (as per the
.Dq anonymous
and
.Dq ftp
logins).
A
.Xr chroot 2
is performed after login.
.It Sy CHROOT
.Xr chroot 2 ed
users (as per
.Xr ftpchroot 5 ) .
A
.Xr chroot 2
is performed after login.
.It Sy REAL
Normal users.
.El
.Pp
The
.Xr ftpd 8
.Sy STAT
command will return the class settings for the current user as defined by
.Nm "" .
.Pp
Each configuration line may be one of:
.Bl -tag -width 4n
.It Sy advertise Ar class Ar host
Set the address to advertise in the response to the
.Sy PASV
and
.Sy LPSV
commands to the address for
.Ar host
(which may be either a host name or IP address).
This may be useful in some firewall configurations, although many
ftp clients may not work if the address being advertised is different
to the address that they've connected to.
If
.Ar class
is
.Dq none
or no argument is given, disable this.
.It Sy checkportcmd Ar class Op Sy off
Check the
.Sy PORT
command for validity.
The
.Sy PORT
command will fail if the IP address specified does not match the
.Tn FTP
command connection, or if the remote TCP port number is less than
.Dv IPPORT_RESERVED .
It is
.Em strongly
encouraged that this option be used, espcially for sites concerned
with potential security problems with
.Tn FTP
bounce attacks.
If
.Ar class
is
.Dq none
or
.Sy off
is given, disable this feature, otherwise enable it.
.It Sy chroot Ar class Op Sy pathformat
If
.Ar pathformat
is not given or
.Ar class
is
.Dq none ,
use the default behaviour (see below).
Otherwise,
.Ar pathformat
is parsed to create a directory to create as the root directory with
.Xr chroot 2
into upon login.
.Pp
.Ar pathformat
can contain the following escape strings:
.Bl -tag -width "Escape" -offset indent -compact
.It Sy "Escape"
.Sy Description
.It "\&%c"
Class name.
.It "\&%d"
Home directory of user.
.It "\&%u"
User name.
.It "\&%\&%"
A
.Dq \&%
character.
.El
.Pp
The default root directory is:
.Bl -tag -width "CHROOT" -offset indent -compact
.It Sy CHROOT
The user's home directory.
.It Sy GUEST
If
.Fl a Ar anondir
is given, use
.Ar anondir ,
otherwise the home directory of the
.Sq ftp
user.
.It Sy REAL
By default no
.Xr chroot 2
is performed.
.El
.It Sy classtype Ar class Ar type
Set the class type of
.Ar class
to
.Ar type
(see above).
.It Xo Sy conversion Ar class
.Ar suffix Op Ar "type disable command"
.Xc
Define an automatic in-line file conversion.
If a file to retrieve ends in
.Ar suffix ,
and a real file (sans
.Ar suffix )
exists, then the output of
.Ar command
is returned instead of the contents of the file.
.Pp
.Bl -tag -width "disable" -offset indent
.It Ar suffix
The suffix to initiate the conversion.
.It Ar type
A list of valid filetypes for the conversion.
Valid types are:
.Sq f
(file), and
.Sq d
(directory).
.It Ar disable
The name of file that will prevent conversion if it exists.
A file name of
.Dq Pa \&.
will prevent this disabling action
(i.e., the conversion is always permitted.)
.It Ar command
The command to run for the conversion.
The first word should be the full path name
of the command, as
.Xr execv 3
is used to execute the command.
All instances of the word
.Dq %s
in
.Ar command
are replaced with the requested file (sans
.Ar suffix ) .
.El
.Pp
Conversion directives specified later in the file override earlier
conversions with the same suffix.
.It Sy display Ar class Op Ar file
If
.Ar file
is not given or
.Ar class
is
.Dq none ,
disable this.
Otherwise, each time the user enters a new directory, check if
.Ar file
exists, and if so, display its contents to the user.
Escape sequences are supported; refer to
.Sx Display file escape sequences
in
.Xr ftpd 8
for more information.
.It Sy homedir Ar class Op Sy pathformat
If
.Ar pathformat
is not given or
.Ar class
is
.Dq none ,
use the default behaviour (see below).
Otherwise,
.Ar pathformat
is parsed to create a directory to change into upon login, and to use
as the
.Sq home
directory of the user for tilde expansion in pathnames, etc.
.Ar pathformat
is parsed as per the
.Sy chroot
directive.
.Pp
The default home directory is the home directory of the user for
.Sy REAL
users, and
.Pa /
for
.Sy GUEST
and
.Sy CHROOT
users.
.It Xo Sy limit Ar class
.Ar count Op Ar file
.Xc
Limit the maximum number of concurrent connections for
.Ar class
to
.Ar count ,
with
.Sq 0
meaning unlimited connections.
If the limit is exceeded and
.Ar file
is given, display its contents to the user.
If
.Ar class
is
.Dq none
or
.Ar count
is not specified, disable this.
If
.Ar file
is a relative path, it will be searched for in
.Pa /etc
(which can be overridden with
.Fl c Ar confdir ) .
.It Sy maxfilesize Ar class Ar size
Set the maximum size of an uploaded file to
.Ar size .
If
.Ar class
is
.Dq none
or no argument is given, disable this.
.It Sy maxtimeout Ar class Ar time
Set the maximum timeout period that a client may request,
defaulting to two hours.
This cannot be less than 30 seconds, or the value for
.Sy timeout .
If
.Ar class
is
.Dq none
or
.Ar time
is not specified, set to default of 2 hours.
.It Sy modify Ar class Op Sy off
If
.Ar class
is
.Dq none
or
.Sy off
is given, disable the following commands:
.Sy CHMOD ,
.Sy DELE ,
.Sy MKD ,
.Sy RMD ,
.Sy RNFR ,
and
.Sy UMASK .
Otherwise, enable them.
.It Sy motd Ar class Op Ar file
If
.Ar file
is not given or
.Ar class
is
.Dq none ,
disable this.
Otherwise, use
.Ar file
as the message of the day file to display after login.
Escape sequences are supported; refer to
.Sx Display file escape sequences
in
.Xr ftpd 8
for more information.
If
.Ar file
is a relative path, it will be searched for in
.Pa /etc
(which can be overridden with
.Fl c Ar confdir ) .
.It Sy notify Ar class Op Ar fileglob
If
.Ar fileglob
is not given or
.Ar class
is
.Dq none ,
disable this.
Otherwise, each time the user enters a new directory,
notify the user of any files matching
.Ar fileglob .
.It Sy passive Ar class Op Sy off
If
.Ar class
is
.Dq none
or
.Sy off
is given, disallow passive
.Sy ( PASV ,
.Sy LPSV ,
and
.Sy EPSV )
connections.
Otherwise, enable them.
.It Sy portrange Ar class Ar min Ar max
Set the range of port number which will be used for the passive data port.
.Ar max
must be greater than
.Ar min ,
and both numbers must be be between
.Dv IPPORT_RESERVED
(1024) and 65535.
If
.Ar class
is
.Dq none
or no arguments are given, disable this.
.It Sy rateget Ar class Ar rate
Set the maximum get
.Pq Sy RETR
transfer rate throttle for
.Ar class
to
.Ar rate
bytes per second.
If
.Ar rate
is 0, the throttle is disabled.
If
.Ar class
is
.Dq none
or no arguments are given, disable this.
.Pp
An optional suffix may be provided, which changes the intrepretation of
.Ar rate
as follows:
.Bl -tag -width 3n -offset indent -compact
.It b
Causes no modification. (Default; optional)
.It k
Kilo; multiply the argument by 1024
.It m
Mega; multiply the argument by 1048576
.It g
Giga; multiply the argument by 1073741824
.It t
Tera; multiply the argument by 1099511627776
.El
.It Sy rateput Ar class Ar rate
Set the maximum put
.Pq Sy STOR
transfer rate throttle for
.Ar class
to
.Ar rate
bytes per second,
which is parsed as per
.Sy rateget Ar rate .

is
.Dq none
or no arguments are given, disable this.
.It Sy sanenames Ar class Op Sy off
If
.Ar class
is
.Dq none
or
.Sy off
is given, allow uploaded file names to contain any characters valid for a
file name.
Otherwise, only permit file names which don't start with a
.Sq \&.
and only comprise of characters from the set
.Dq [-+,._A-Za-z0-9] .
.It Sy template Ar class Op Ar refclass
Define
.Ar refclass
as the
.Sq template
for
.Ar class ;
any reference to
.Ar refclass
in following directives will also apply to members of
.Ar class .
This is useful to define a template class so that other classes which are
to share common attributes can be easily defined without unnecessary
duplication.
There can be only one template defined at a time.
If
.Ar refclass
is not given, disable the template for
.Ar class .
.It Sy timeout Ar class Ar time
Set the inactivity timeout period.
(the default is fifteen minutes).
This cannot be less than 30 seconds, or greater than the value for
.Sy maxtimeout .
If

.Dt FTPUSERS 5
.Os
.Sh NAME
.Nm ftpusers ,
.Nm ftpchroot
.Nd
.Xr ftpd 8
access control file
.Sh DESCRIPTION
The
.Nm
file provides user access control for
.Xr ftpd 8
by defining which users may login.
.Pp
If the
.Nm
file does not exist, all users are denied access.
.Pp
A
.Dq \e
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
.Dq #
is the comment character, and all characters from it to the end of
line are ignored (unless it is escaped with the escape character).
.Pp
The syntax of each line is:
.Dl userglob[:groupglob][@host] [directive [class]]
.Pp
These elements are:
.Bl -tag -width "groupglob" -offset indent
.It Sy userglob
matched against the user name, using
.Xr fnmatch 3
glob matching
(e.g,
.Sq f* ) .
.It Sy groupglob
matched against all the groups that the user is a member of, using
.Xr fnmatch 3
glob matching
(e.g,
.Sq *src ) .
.It Sy host
either a CIDR address (refer to
.Xr inet_net_pton 3 )
to match against the remote address
(e.g,
.Sq 1.2.3.4/24 ) ,
or a glob to match against the remote hostname
(e.g,
.Sq *.netbsd.org ) .
.It Sy directive
If
.Dq allow
or
.Dq yes
the user is allowed access.
If
.Dq deny
or
.Dq no ,
or
.Sy directive
is not given, the user is denied access.
.It Sy class
defines the class to use in
.Xr ftpd.conf 5 .
.El
.Pp
If
.Sy class
is not given, it defaults to one of the following:
.Bl -tag -width "chroot" -offset indent
.It Sy chroot
If there is a match in
.Sx /etc/ftpchroot
for the user.
.It Sy guest
If the user name is
.Dq anonymous
or
.Sq ftp .
.It Sy real
If neither of the above is true.
.El
.Pp
No further comparisons are attempted after the first successful match.
If no match is found, the user is granted access.
This syntax is backward-compatable with the old syntax.
.Pp
If a user requests a guest login, the
.Xr ftpd 8
server checks to see that
both
.Dq anonymous
and
.Dq ftp
have access, so if you deny all users by default, you will need to add both
.Dq "anonymous allow"
and
.Dq "ftp allow"
to
.Pa /etc/ftpusers
in order to allow guest logins.
.Ss /etc/ftpchroot
The file
.Pa /etc/ftpchroot
is used to determine which users will have their session's root directory
changed (using
.Xr chroot 2 ) ,
either to the directory specified in the
.Xr ftpd.conf 5
.Sy 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.
.Pp
The syntax is similar to
.Nm "" ,
except that the
.Sy 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-compatable with the old syntax.

is not available?
- IF_NAMESIZE not available on darwin
fix internalls (actually fts) on IRIX
enable utmp stuff (need to make it portable)
enable wtmp stuff (need to make it portable)
enable kerberos support once its fixed?
add getenv(3) to replace putenv(3) cruft?
