| NAME
| |
| smtp-sink - parallelized SMTP/LMTP test server
| |
|
| |
|
| SYNOPSIS
| | ==Menjalankan== |
| smtp-sink [options] [inet:][host]:port backlog
| |
|
| |
|
| smtp-sink [options] unix:pathname backlog
| | Pertama-tama sinkronkan waktu di kedua mesin |
|
| |
|
| DESCRIPTION
| | ntpdate pool.ntp.org |
| smtp-sink listens on the named host (or address) and port. It takes
| |
| SMTP messages from the network and throws them away. The purpose is to
| |
| measure client performance, not protocol compliance.
| |
|
| |
|
| smtp-sink may also be configured to capture each mail delivery transac-
| |
| tion to file. Since disk latencies are large compared to network
| |
| delays, this mode of operation can reduce the maximal performance by
| |
| several orders of magnitude.
| |
|
| |
|
| Connections can be accepted on IPv4 or IPv6 endpoints, or on
| | Setup SMTP listenser di port 25 (misalnya di localhost) |
| UNIX-domain sockets. IPv4 and IPv6 are the default. This program is
| |
| the complement of the smtp-source(1) program.
| |
|
| |
|
| Note: this is an unsupported test program. No attempt is made to main-
| |
| tain compatibility between successive versions.
| |
|
| |
|
| Arguments:
| | smtp-sink -c localhost:25 1000 |
|
| |
|
| -4 Support IPv4 only. This option has no effect when Postfix is
| |
| built without IPv6 support.
| |
|
| |
|
| -6 Support IPv6 only. This option is not available when Postfix is
| | Bisa menggunakan postfix untuk mengirim atau dengan smtp-source. |
| built without IPv6 support.
| |
|
| |
|
| -8 Do not announce 8BITMIME support.
| | time smtp-source -s 20 -l 5120 -m 100 -c 100 -f sender@example.com -t recipient@example.com localhost:25 |
| | |
| -a Do not announce SASL authentication support.
| |
| | |
| -A delay
| |
| Wait delay seconds after responding to DATA, then abort prema-
| |
| turely with a 550 reply status. Do not read further input from
| |
| the client; this is an attempt to block the client before it
| |
| sends ".". Specify a zero delay value to abort immediately.
| |
| | |
| -b soft-bounce-reply
| |
| Use soft-bounce-reply for soft reject responses. The default
| |
| reply is "450 4.3.0 Error: command failed".
| |
| | |
| -B hard-bounce-reply
| |
| Use hard-bounce-reply for hard reject responses. The default
| |
| reply is "500 5.3.0 Error: command failed".
| |
| | |
| -c Display running counters that are updated whenever an SMTP ses-
| |
| sion ends, a QUIT command is executed, or when "." is received.
| |
| | |
| -C Disable XCLIENT support.
| |
| | |
| -d dump-template
| |
| Dump each mail transaction to a single-message file whose name
| |
| is created by expanding the dump-template via strftime(3) and
| |
| appending a pseudo-random hexadecimal number (example:
| |
| "%Y%m%d%H/%M." expands into "2006081203/05.809a62e3"). If the
| |
| template contains "/" characters, missing directories are cre-
| |
| ated automatically. The message dump format is described below.
| |
| | |
| Note: this option keeps one capture file open for every mail
| |
| transaction in progress.
| |
| | |
| -D dump-template
| |
| Append mail transactions to a multi-message dump file whose name
| |
| is created by expanding the dump-template via strftime(3). If
| |
| the template contains "/" characters, missing directories are
| |
| created automatically. The message dump format is described
| |
| below.
| |
| | |
| Note: this option keeps one capture file open for every mail
| |
| transaction in progress.
| |
| | |
| -e Do not announce ESMTP support.
| |
| | |
| -E Do not announce ENHANCEDSTATUSCODES support.
| |
| | |
| -f command,command,...
| |
| Reject the specified commands with a hard (5xx) error code.
| |
| This option implies -p.
| |
| | |
| Examples of commands are CONNECT, HELO, EHLO, LHLO, MAIL, RCPT,
| |
| VRFY, DATA, ., RSET, NOOP, and QUIT. Separate command names by
| |
| white space or commas, and use quotes to protect white space
| |
| from the shell. Command names are case-insensitive.
| |
| | |
| -F Disable XFORWARD support.
| |
| | |
| -h hostname
| |
| Use hostname in the SMTP greeting, in the HELO response, and in
| |
| the EHLO response. The default hostname is "smtp-sink".
| |
| | |
| -H delay
| |
| Delay the first read operation after receiving DATA (time in
| |
| seconds). Combine with a large test message and a small TCP win-
| |
| dow size (see the -T option) to test the Postfix client
| |
| write_wait() implementation.
| |
| | |
| -L Enable LMTP instead of SMTP.
| |
| | |
| -m count (default: 256)
| |
| An upper bound on the maximal number of simultaneous connections
| |
| that smtp-sink will handle. This prevents the process from run-
| |
| ning out of file descriptors. Excess connections will stay
| |
| queued in the TCP/IP stack.
| |
| | |
| -M count
| |
| Terminate after receiving count messages.
| |
| | |
| -n count
| |
| Terminate after count sessions.
| |
| | |
| -N Do not announce support for DSN.
| |
| | |
| -p Do not announce support for ESMTP command pipelining.
| |
| | |
| -P Change the server greeting so that it appears to come through a
| |
| CISCO PIX system. Implies -e.
| |
| | |
| -q command,command,...
| |
| Disconnect (without replying) after receiving one of the speci-
| |
| fied commands.
| |
| | |
| Examples of commands are CONNECT, HELO, EHLO, LHLO, MAIL, RCPT,
| |
| VRFY, DATA, ., RSET, NOOP, and QUIT. Separate command names by
| |
| white space or commas, and use quotes to protect white space
| |
| from the shell. Command names are case-insensitive.
| |
| | |
| -Q command,command,...
| |
| Send a 421 reply and disconnect after receiving one of the spec-
| |
| ified commands.
| |
| | |
| Examples of commands are CONNECT, HELO, EHLO, LHLO, MAIL, RCPT,
| |
| VRFY, DATA, ., RSET, NOOP, and QUIT. Separate command names by
| |
| white space or commas, and use quotes to protect white space
| |
| from the shell. Command names are case-insensitive.
| |
| | |
| -r command,command,...
| |
| Reject the specified commands with a soft (4xx) error code.
| |
| This option implies -p.
| |
| | |
| Examples of commands are CONNECT, HELO, EHLO, LHLO, MAIL, RCPT,
| |
| VRFY, DATA, ., RSET, NOOP, and QUIT. Separate command names by
| |
| white space or commas, and use quotes to protect white space
| |
| from the shell. Command names are case-insensitive.
| |
| | |
| -R root-directory
| |
| Change the process root directory to the specified location.
| |
| This option requires super-user privileges. See also the -u
| |
| option.
| |
| | |
| -s command,command,...
| |
| Log the named commands to syslogd.
| |
| | |
| Examples of commands are CONNECT, HELO, EHLO, LHLO, MAIL, RCPT,
| |
| VRFY, DATA, ., RSET, NOOP, and QUIT. Separate command names by
| |
| white space or commas, and use quotes to protect white space
| |
| from the shell. Command names are case-insensitive.
| |
| | |
| -S start-string
| |
| An optional string that is prepended to each message that is
| |
| written to a dump file (see the dump file format description
| |
| below). The following C escape sequences are supported: \a
| |
| (bell), \b (backspace), \f (formfeed), \n (newline), \r (car-
| |
| riage return), \t (horizontal tab), \v (vertical tab), \ddd (up
| |
| to three octal digits) and \\ (the backslash character).
| |
| | |
| -t timeout (default: 100)
| |
| Limit the time for receiving a command or sending a response.
| |
| The time limit is specified in seconds.
| |
| | |
| -T windowsize
| |
| Override the default TCP window size. To work around broken TCP
| |
| window scaling implementations, specify a value > 0 and < 65536.
| |
| | |
| -u username
| |
| Switch to the specified user privileges after opening the net-
| |
| work socket and optionally changing the process root directory.
| |
| This option is required when the process runs with super-user
| |
| privileges. See also the -R option.
| |
| | |
| -v Show the SMTP conversations.
| |
| | |
| -w delay
| |
| Wait delay seconds before responding to a DATA command.
| |
| | |
| -W command:delay[:odds]
| |
| Wait delay seconds before responding to command. If odds is
| |
| also specified (a number between 1-99 inclusive), wait for a
| |
| random multiple of delay. The random multiplier is equal to the
| |
| number of times the program needs to roll a dice with a range of
| |
| 0..99 inclusive, before the dice produces a result greater than
| |
| or equal to odds.
| |
| | |
| [inet:][host]:port
| |
| Listen on network interface host (default: any interface) TCP
| |
| port port. Both host and port may be specified in numeric or
| |
| symbolic form.
| |
| | |
| unix:pathname
| |
| Listen on the UNIX-domain socket at pathname.
| |
| | |
| backlog
| |
| The maximum length the queue of pending connections, as defined
| |
| by the listen(2) system call.
| |
| | |
| DUMP FILE FORMAT
| |
| Each dumped message contains a sequence of text lines, terminated with
| |
| the newline character. The sequence of information is as follows:
| |
| | |
| o The optional string specified with the -S option.
| |
| | |
| o The smtp-sink generated headers as documented below.
| |
| | |
| o The message header and body as received from the SMTP client.
| |
| | |
| o An empty line.
| |
| | |
| The format of the smtp-sink generated headers is as follows:
| |
| | |
| X-Client-Addr: text
| |
| The client IP address without enclosing []. An IPv6 address is
| |
| prefixed with "ipv6:". This record is always present.
| |
| | |
| X-Client-Proto: text
| |
| The client protocol: SMTP, ESMTP or LMTP. This record is always
| |
| present.
| |
| | |
| X-Helo-Args: text
| |
| The arguments of the last HELO or EHLO command before this mail
| |
| delivery transaction. This record is present only if the client
| |
| sent a recognizable HELO or EHLO command before the DATA com-
| |
| mand.
| |
| | |
| X-Mail-Args: text
| |
| The arguments of the MAIL command that started this mail deliv-
| |
| ery transaction. This record is present exactly once.
| |
| | |
| X-Rcpt-Args: text
| |
| The arguments of an RCPT command within this mail delivery
| |
| transaction. There is one record for each RCPT command, and they
| |
| are in the order as sent by the client.
| |
| | |
| Received: text
| |
| A message header for compatibility with mail processing soft-
| |
| ware. This three-line header marks the end of the headers pro-
| |
| vided by smtp-sink, and is formatted as follows:
| |
| | |
| from helo ([addr])
| |
| The HELO or EHLO command argument and client IP address.
| |
| If the client did not send HELO or EHLO, the client IP
| |
| address is used instead.
| |
| | |
| by host (smtp-sink) with proto id random;
| |
| The hostname specified with the -h option, the client
| |
| protocol (see X-Client-Proto above), and the pseudo-ran-
| |
| dom portion of the per-message capture file name.
| |
| | |
| time-stamp
| |
| A time stamp as defined in RFC 2822.
