.Sh DESCRIPTION
|
||||||
|
.Nm Ftpd
|
||||||
|
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 d
|
||||||
|
Debugging information is written to the syslog using LOG_FTP.
|
||||||
|
.It Fl l
|
||||||
|
Each successful and failed
|
||||||
|
.Xr ftp 1
|
||||||
|
session is logged using syslog with a facility of LOG_FTP.
|
||||||
|
If this option is specified twice, the retrieve (get), store (put), append,
|
||||||
|
delete, make directory, remove directory and rename operations and
|
||||||
|
their filename arguments are also logged.
|
||||||
|
.It Fl T
|
||||||
|
A client may also request a different timeout period;
|
||||||
|
the maximum period allowed may be set to
|
||||||
|
.Ar timeout
|
||||||
|
seconds with the
|
||||||
|
.Fl T
|
||||||
|
option.
|
||||||
|
The default limit is 2 hours.
|
||||||
|
.It Fl t
|
||||||
|
The inactivity timeout period is set to
|
||||||
|
.Ar timeout
|
||||||
|
seconds (the default is 15 minutes).
|
||||||
|
.El
|
||||||
|
.Pp
|
||||||
|
The file
|
||||||
|
.Pa /etc/nologin
|
||||||
|
can be used to disable 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,
|
||||||
|
.Nm
|
||||||
|
prints it after a successful login.
|
||||||
|
.Pp
|

The ftp server currently supports the following ftp requests.

.Tn UNIX
|
||||||
|
specific commands are supported
|
||||||
|
by the
|
||||||
|
SITE request.

|

|

.Pp
|
||||||
|
The remaining ftp requests specified in Internet RFC 959
|
||||||
|
are
|
||||||
|
recognized, but not implemented.
|
||||||
|
MDTM and SIZE are not specified in RFC 959, but will appear in the
|
||||||
|
next updated FTP RFC.
|
||||||
|
.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.
|
||||||
|
If a
|
||||||
|
STAT
|
||||||
|
command is received during a data transfer, preceded by a Telnet IP
|
||||||
|
and Synch, transfer status will be returned.
|
||||||
|
.Pp
|
||||||
|
.Nm Ftpd
|
||||||
|
interprets file names according to the
|
||||||
|
.Dq globbing
|
||||||
|
conventions used by
|
||||||
|
.Xr csh 1 .
|
||||||
|
This allows users to utilize the metacharacters
|
||||||
|
.Dq Li \&*?[]{}~ .
|
||||||
|
.Pp
|
||||||
|
.Nm Ftpd
|
||||||
|
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 USER
|
||||||
|
command will include an S/Key challenge. The client may choose to respond
|
||||||
|
with a 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 not appear in the file
|
||||||
|
.Pa /etc/ftpusers .
|
||||||
|
.It
|
||||||
|
The user must have a standard shell returned by
|
||||||
|
.Xr getusershell 3 .
|
||||||
|
.It
|
||||||
|
If the user name appears in the file
|
||||||
|
.Pa /etc/ftpchroot
|
||||||
|
the session's root will be changed to the user's login directory by
|
||||||
|
.Xr chroot 2
|
||||||
|
as for an
|
||||||
|
.Dq anonymous
|
||||||
|
or
|
||||||
|
.Dq ftp
|
||||||
|
account (see next item). 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 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).
|
||||||
|
.El
|
||||||
|
.Pp
|
||||||
|
In the last case,
|
||||||
|
.Nm ftpd
|
||||||
|
takes special measures to restrict the client's access privileges.
|
||||||
|
The server performs a
|
||||||
|
.Xr chroot 2
|
||||||
|
to the home directory of the
|
||||||
|
.Dq ftp
|
||||||
|
user.
|
||||||
|
In order that system security is not breached, it is recommended
|
||||||
|
that the
|
||||||
|
.Dq ftp
|
||||||
|
subtree be constructed with care, following these rules:
|
||||||
|
.Bl -tag -width "~ftp/pub" -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).
|
||||||
|
The program
|
||||||
|
.Xr ls 1
|
||||||
|
must be present to support the list command.
|
||||||
|
This program should be mode 111.
|
||||||
|
.It Pa ~ftp/etc
|
||||||
|
Make this directory owned by
|
||||||
|
.Dq root
|
||||||
|
and unwritable by anyone (mode 555).
|
||||||
|
The files
|
||||||
|
.Xr passwd 5
|
||||||
|
and
|
||||||
|
.Xr group 5
|
||||||
|
must be present for the
|
||||||
|
.Xr ls
|
||||||
|
command to be able to produce owner names rather than numbers.
|
||||||
|
The password field in
|
||||||
|
.Xr passwd
|
||||||
|
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
|
||||||
|
Make this directory mode 777 and owned by
|
||||||
|
.Dq ftp .
|
||||||
|
Guests
|
||||||
|
can then place files which are to be accessible via the anonymous

|
||||||
|
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.
