-.Dd August 4, 2005 -.Dt FTPD 8 -.Os -.Sh NAME -.Nm ftpd -.Nd -Internet File Transfer Protocol server -.Sh SYNOPSIS -.Nm -.Op Fl 46DdHlQqrsUuWwX -.Op Fl a Ar anondir -.Op Fl C Ar user -.Op Fl c Ar confdir -.Op Fl e Ar emailaddr -.Op Fl h Ar hostname -.Op Fl L Ar xferlogfile -.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 4 -When -.Fl D -is specified, bind to IPv4 addresses only. -.It Fl 6 -When -.Fl D -is specified, bind to IPv6 addresses only. -.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 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 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 D -Run as daemon. -.Nm -will listen on the default FTP port for incoming connections -and fork a child for each connection. -This is lower overhead than starting -.Nm -from -.Xr inetd 8 -and thus might be useful on busy servers to reduce load. -.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 -Equivalent to -.Do --h -`hostname` -.Dc . -.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 L Ar xferlogfile -Log -.Tn wu-ftpd -style -.Sq xferlog -entries to -.Ar xferlogfile . -.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 -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 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 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 -Don't log each concurrent -.Tn FTP -session to -.Pa /var/run/utmp . -This is the default. -.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 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 -Don't log each -.Tn FTP -session to -.Pa /var/log/wtmp . -.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 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: //' \*[Gt] 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

-(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. -.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. -.Pp -.Nm -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. diff --git a/contrib/lukemftpd/src/ftpd.c b/contrib/lukemftpd/src/ftpd.c deleted file mode 100644 index 8b06649..0000000 ---

-.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 Ns 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 , -unless the -.Sy private -directive is set for the class. -.Pp -Each configuration line may be one of: -.Bl -tag -width 4n -.It Sy advertize Ar class Op 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 -.Ar host -not is specified, 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, especially for sites concerned -with potential security problems with -.Tn FTP -bounce attacks. -If -.Ar class -is -.Dq none -or -.Sy off -is specified, disable this feature, otherwise enable it. -.It Sy chroot Ar class Op Sy pathformat -If -.Ar pathformat -is not specified or -.Ar class -is -.Dq none , -use the default behavior (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 specified, 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 denyquick Ar class Op Sy off -Enforce -.Xr ftpusers 5 -rules after the -.Sy USER -command is received, rather than after the -.Sy PASS -command is received. -Whilst enabling this feature may allow information leakage about -available accounts (for example, if you allow some users of a -.Sy REAL -or -.Sy CHROOT -class but not others), it is useful in preventing a denied user -(such as -.Sq root ) -from entering their password across an insecure connection. -This option is -.Em strongly -recommended for servers which run an anonymous-only service. -If -.Ar class -is -.Dq none -or -.Sy off -is specified, disable this feature, otherwise enable it. -.It Sy display Ar class Op Ar file -If -.Ar file -is not specified or -.Ar class -is -.Dq none , -disable this. -Otherwise, each time the user enters a new directory,

hidesymlinks Ar class Op Sy off -If -.Ar class -is -.Dq none -or -.Sy off -is specified, disable this feature. -Otherwise, the -.Sy LIST -command lists symbolic links as the file or directory the link -references -.Pq Dq Li "ls -LlA" . -Servers which run an anonymous service may wish to enable this -feature for -.Sy GUEST -users, so that symbolic links do not leak names in -directories that are not searchable by -.Sy GUEST -users. -.It Sy homedir Ar class Op Sy pathformat -If -.Ar pathformat -is not specified or -.Ar class -is -.Dq none , -use the default behavior (see below). -Otherwise, -.Ar
