DESCRIPTION

ftpd is the DARPA Internet File Transfer Protocol server. It expects to be run by the Internet daemon

(see inetd (1M) and inetd.conf (4)). inetd runs

ftpd when a service request is received at the port indi-

cated in the

ftp service speciﬁcation in

/etc/services (see services (4)).

Options

ftpd recognizes the following options and command-line arguments.

-a Enables the use of the conﬁguration ﬁle

/etc/ftpd/ftpaccess

. (see ftpac-

cess(4)).

-A Disables the use of the conﬁguration ﬁle

/etc/ftpd/ftpaccess

. (see ftpac-

cess(4)).

-B size Sets the buffer size of the data socket to size blocks of 1024 bytes. The valid range

for size is from 1 to 2097151 (default is 56).

Note: A large buffer size will improve the performance of ftpd on fast links, but

may cause long connection times on slow links (for example, X.25).

Note: If the buffer size needs to be set to any value other than multiples of 1024

bytes, use "B" immediately after size without any space. The size value will be

taken in terms of bytes. For example, to set the buffer size to a value equal to

"1500", use -B 1500B.

-c ctrlport

-C dataport Overrides the control and the data port numbers respectively that is used by the

daemon. Normally, the daemon determines the port numbers by looking in

/etc/services (see services (4)) for "ftp" and "ftp-data". If there is no

/etc/services entry for "ftp-data" and the -C

option is not speciﬁed, the dae-

mon uses the port just prior to the control connection port. The

-c and -C options

are both available if running as a standalone daemon. Otherwise, only the -C

option can be used.

-i Logs all the ﬁles received by ftpd server to xferlog (see xferlog (5)). This option

is overridden by the /etc/ftpd/ftpaccess

ﬁle. (see ftpaccess (4)).

-I Enables the use of RFC931 (AUTH/ident) to attempt to determine the username on

the client.

-K Applicable only in a secure environment based on Kerberos V5. Causes access to be

denied if network authentication fails. See sis (5).

-l Causes each FTP session to be logged in the syslog ﬁle.

-L Logs all commands sent to the ftpd server to be logged to the syslog. The -L

option is overridden by the /etc/ftpd/ftpaccess ﬁle (see ftpaccess (4)). If the

-L option is used, commands will be logged to syslog by default.

-m number_of_tries

Speciﬁes the number of tries for a bind() socket call.

-M locale Specify the locale (see locale (1)) that ftpd should use. The default locale for ftpd

is C. This may create a problem when handling some multibyte characters which

are locale speciﬁc. In this case, use the -M option to specify the appropriate locale.

Note: usage of this option may result in increased memory usage, decreased per-

formance, and will process characters which belong to the speciﬁed locale only.

-n nice_value Sets the nice value for an ftpd process. When using this option, make sure that

the nice clause in /etc/ftpd/ftpaccess ﬁle (see ftpaccess (4)) is not set.

ftpd(1M) ftpd(1M) -o Logs all files transmitted by ftpd to xferlog (see xferlog (5)). It logs outgoing This option is overridden by the files from the ftpd server. /etc/ftpd/ftpaccess file (see ftpaccess (4)). -p The default action of ftpd does not allow usage of reserved ports as the originating port on the client’s system i.e., the PORT command cannot specify a reserved port. This option allows the client to specify a reserved port.
PAGE 3
ftpd(1M) ftpd(1M) AUTH SSL command. This flag is provided for clients that expect a 334 response for an AUTH SSL command. By default, this flag is not set. certsok Configures ftpd to NOT check the CA certificate and CRL certificate for the FTP client presented certificate. HP recommends to not enable this flag. This flag is provided only for debugging purpose. By default, this flag is not set.
PAGE 4
ftpd(1M) ftpd(1M) needpass ftpd requests a password even if the FTP client certificate has been successfully verified. cipher=OPTION Specifies the cipher suite to be used during TLS negotiation. The default cipher suite used is: ALL:!ADH:RC4+RSA:+SSLv2:@STRENGTH config=file Specifies the ftpd TLS configuration file. The -z flags and -z options can be specified in this file (without the -z prefix) instead of specifying them on the command line. The configuration file does not have a default value.
PAGE 5
ftpd(1M) ftpd(1M) Supported Commands The ftpd server currently supports the following commands. The commands are not case sensitive. Therefore, uppercase and lowercase commands are interpreted as equivalent.
PAGE 6
ftpd(1M) CCC ENC MIC PROT PBSZ ftpd(1M) Clear command channel Privacy protected command Integrity protected command Data channel protection level (level "C" only) Protection buffer size (has no effect) These commands are described in draft 8 of the FTP security extensions. SITE Command The following non-standard or HP-UX specific commands are supported by the SITE command: Command A UMASK IDLE CHMOD HELP NEWER MINFO GROUP GPASS EXEC fA Description Change umask. (e.g., SITE UMASK 002) Set idle-timer.
PAGE 7
ftpd(1M) ftpd(1M) Optionally, a system administrator can permit public access or "anonymous FTP." If this has been set up, users can access the anonymous FTP account with the user name anonymous or ftp and any non-null password (by convention, the client host’s name). ftpd does a chroot() to the home directory of user ftp, thus limiting anonymous FTP users’ access to the system. If the user name is anonymous or ftp, an anonymous FTP account must be present in the password file (user ftp).
PAGE 8
ftpd(1M) ftpd(1M) number is useful for programs; the text is useful for users. The number must conform to this standard, but the text can vary. The first digit of the message indicates whether the reply is good, bad, or incomplete. Five values exist for the first digit. The values and the interpretations of the values are: 1 The requested action is being initiated; expect another reply before proceeding with a new command. 2 The requested action is complete. The server is ready for a new request.
PAGE 9
ftpd(1M) ftpd(1M) filename filename.tar filename filename.tar.Z Tar filename before transmitting Tar and compress filename before transmitting Also, the FTP server will attempt to check for valid e-mail addresses and notify the user if invalid e-mail addresses are found. For users whose FTP client will hang on "long replies" (that is, multiline responses), using a dash as the first character of the password will disable this "long replies" feature.
