ftpd200 --- FTP server program for Minix 2.0
|
||||
written by Michael Temari <Michael@TemWare.Com> release 2.00 2005-02-25
|
||||
|
||||
Full download: <a href="/pub/contrib/ftpd200.tar.Z">ftpd200.tar.Z</a>
|
||||
|
||||
Ftpd is the File Transfer Protocol (FTP) server.
|
||||
|
||||
Important: Release 2.00 incorporates an improved mechanism to restrict
|
||||
execution of commands on the server. This is done through use of a
|
||||
shell script, ftpdsh. Any earlier ftpd version in use on a system
|
||||
accessible from the Internet should be upgraded at least to version 1.01,
|
||||
version 2.00 is preferable.
|
||||
|
||||
Installation: unpack the tarball in /usr/local/src or another directory
|
||||
of your choice:
|
||||
zcat < ftpd200.tar.Z | tar xvfp -
|
||||
|
||||
The ftpd200 directory will be created. Read the Makefile to see how
|
||||
the program is compiled and installed:
|
||||
|
||||
make (or make ftpd) -- compiles the binary
|
||||
make install -- installs /usr/bin/in.ftpd, and ftpdsh. Also installs
|
||||
setup.anonftp script.
|
||||
make installman -- installs new ftpd.8 man page in /usr/local/man/man8
|
||||
|
||||
The shell script setup.anonftp sets up and verifies configuration for
|
||||
anonymous ftp. If you provide anonymous ftp you are letting anyone in
|
||||
the whole wide world execute a program on your computer. You want to
|
||||
make sure it's set up correctly so outsiders can't mess with things
|
||||
they shouldn't.
|
||||
|
||||
This file is included as README in the source directory. For more
|
||||
notes on compiling and installing, also please see the file README2.

README2: additional notes on compiling and installing ftpd.
|
||||
|
||||
Note that the Makefile install options will replace files in /usr/bin
|
||||
and /usr/man that were installed with the Minix distribution. If you
|
||||
are not sure you want to do this you can either rename the original
|
||||
in.ftpd binary, the anonftp.* scripts, and the ftpd.8 man page to
|
||||
prevent them from being replaced, or you can edit the Makefile to
|
||||
change the directory values:
|
||||
BINDIR= /usr/local/bin
|
||||
MANDIR= /usr/local/man/man8
|
||||
ASW's practice is to rename binaries with a suffix that indicates the
|
||||
original distribution from which they were obtained, i.e., in.ftpd.203
|
||||
for the version distributed with Minix 2.0.3, or with a date code or a
|
||||
version number.
|
||||
|
||||
If you are sure you want to replace the original ftpd provided with your
|
||||
distribution you may want to copy the contents of the unpacked tarball
|
||||
to the main directory tree, in this case /usr/src/commands/ftpd, so that
|
||||
a new version will be compiled if you do a general recompilation of all
|
||||
commands using "make all" or "make compile" in /usr/src. ASW's practice
|
||||
is generally to make a directory in /usr/local/src for new versions of
|
||||
major programs.
|
||||
Also note that if you create a new man page where one did not exist
|
||||
previously you will need to run makewhatis to rebuild the whatis
|
||||
database, i.e.:
|
||||
makewhatis /usr/man
|
||||
or
|
||||
makewhatis /usr/local/man
|
||||
|
||||
Important: the scripts for setting up and maintaining an anonymous ftp
|
||||
installation haven't been checked for a long time, I would appreciate
|
||||
comments.

.SH DESCRIPTION
|
||||
.B Ftpd
|
||||
is the DARPA Internet File Transfer Prototocol
|
||||
server process. The server uses the TCP protocol
|
||||
and listens at the port specified in the ``ftp''
|
||||
service specification; see
|
||||
.BR services (5).
|
||||
.PP
|
||||
The ftp server currently supports the following ftp
|
||||
requests; case is not distinguished.
|
||||

|
||||

|
||||
.PP
|
||||
The remaining ftp requests specified in Internet RFC 959 are
|
||||
recognized, but not implemented.
|
||||
.PP
|
||||
The ftp server will abort an active file transfer only when the
|
||||
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 RFC 959.
|
||||
.PP
|
||||
.B Ftpd
|
||||
interprets file names according to the ``globbing''
|
||||
conventions used by
|
||||
.BR csh (1).
|
||||
This allows users to utilize the metacharacters ``*?[]{}~''.
|
||||
.PP
|
||||
.B Ftpd
|
||||
authenticates users according to two rules.
|
||||
.IP 1)
|
||||
The user name must be in the password data base,
|
||||
.BR /etc/passwd ,
|
||||
and not have a null password. In this case a password
|
||||
must be provided by the client before any file operations
|
||||
may be performed.
|
||||
.IP 2)
|
||||
If the user name is ``anonymous'' or ``ftp'', an
|
||||
anonymous ftp account must be present in the password
|
||||
file (user ``ftp''). In this case the user is allowed
|
||||
to log in by specifying any password (by convention this
|
||||
is given as the client host's name).
|
||||
.PP
|
||||
In the last case,
|
||||
.B ftpd
|
||||
takes special measures to restrict the client's access privileges.
|
||||
The server performs a
|
||||
.BR chroot (2)
|
||||
command to the home directory of the ``ftp'' user.
|
||||
In order that system security is not breached, it is recommended
|
||||
that the ``ftp'' subtree be constructed with care; the following
|
||||
rules are recommended.
|
||||
.IP ~ftp)
|
||||
Make the home directory owned by ``ftp'' and unwritable by anyone.
|
||||
.IP ~ftp/bin)
|
||||
Make this directory owned by the super-user and unwritable by
|
||||
anyone. The program
|
||||
.BR ls (1)
|
||||
must be present to support the list commands.
|
||||
Also,
|
||||
.BR crc (1)
|
||||
must be present to support generating crcs using the site command,
|
||||
.BR tar (1)
|
||||
and
|
||||
.BR compress (1)
|
||||
must be present to support on-the-fly generation of .tar and .tar.Z archives,
|
||||
.BR gzip (1)
|
||||
must be present to support gzip compression, and
|
||||
.BR sh (1)
|
||||
must be present to support
|
||||
.BR ftpdsh (8)
|
||||
which also must be present.
|
||||
.BR ftpdsh controls which binaries can be used.
|
||||
These programs should all have mode 111.
|
||||
.IP ~ftp/etc)
|
||||
Make this directory owned by the super-user and unwritable by
|
||||
anyone. The files
|
||||
.BR passwd (5)
|
||||
and
|
||||
.BR group (5)
|
||||
must be present for the
|
||||
.B ls
|
||||
command to work properly. These files should be mode 444. They can (and
|
||||
should) be stripped down versions so as not to reveal names of users who
|
||||
are not owners of files in the ~ftp/pub directory tree.
|
||||
.IP ~ftp/pub)
|
||||
Make this directory mode 755 and owned by the super-user. Create
|
||||
directories in it owned by users if those users want to manage an
|
||||
anonymous ftp directory.
|
||||
.IP ~ftp/pub/incoming)
|
||||
Optionally create this directory for anonymous uploads. Make it mode
|
||||
777. The FTP daemon will create files with mode 266, so remote users
|
||||
can write a file, but only local users can do something with it.
|
||||
.PP
|
||||
The script
|
||||
.B setup.anonftp
|
||||
can be used to create or check an anonymous FTP tree.
|
||||
.SH "SEE ALSO"
|
||||
.BR ftp (1).
|
||||
.SH BUGS
|
||||
The anonymous account is inherently dangerous and should
|
||||
avoided when possible.
|
||||
.ig \" Minix doesn't have privileged port numbers (yet?)
|
||||
.PP
|
||||
The server must run as the super-user
|
||||
to create sockets with privileged port numbers. It maintains
|
||||
an effective user id of the logged in user, reverting to
|
||||
the super-user only when binding addresses to sockets. The
|
||||
possible security holes have been extensively
|
||||
scrutinized, but are possibly incomplete.
