  Alias      => 'ftp',
  Username   => 'test',
  Password   => 'test',
  RemoteAddr => 'localhost',
  Events     => [ qw( authenticated put_ready put_error put_closed
                      get_begin get_data get_done size ) ]
);

# we are authenticated
sub authenticated {
  $poe_kernel->post('ftp', 'command', 'args');
}

# data connection is ready for data
sub put_ready {
  my ($status, $line, $param) = @_[ARG0..ARG3];

  open FILE, "/etc/passwd" or die $!;

  my ($error, $param) = @_[ARG0,ARG1];

  warn "ERROR: '$error' occured while trying to STOR '$param'";
}

# data connection closed

}

# file on the way...

DESCRIPTION

Client module for FTP

CAVEATS

Untested.

METHODS

spawn

Alias - session name

Username - account username

Password - account password

LocalAddr - unused

LocalPort - unused

RemoteAddr - ftp server

RemotePort - ftp port

Timeout - unused

Blocksize - unused

Events - events you are interested in receiving. See OUTPUT.

INPUT

cd [path]

cdup

delete [filename]

dir

get [filename]

ls

mdtm [filename]

mkdir [dir name]

mode [active passive]

noop

pwd

rmdir [dir name]

site [command]

size [filename]

type [ascii binary]

quit

put_data

After receiving a put_ready event you can post put_data events to send data to the server.

put_close

Closes the data connection. put_closed will be emit when connection is flushed and closed.

OUTPUT

Output is for "simple" ftp events is simply "event". Error cases are "event_error". ARG0 is the numeric code, ARG1 is the text response, and ARG2 is the parameter you made the call with. This is useful since commands such as size do not remind you of this in the server response.

Output for "complex" or data socket ftp commands is creates "event_begin" upon socket connection, "event_data" for each item of data, and "event_done" when all data is done being sent.

Output from put is "put_error" for an error creating a connection or "put_ready". If you receive "put_ready" you can post "put_data" commands to the component to have it write. A "put_done" command closes and writes. Upon completion, a "put_closed" or "put_error" is posted back to you.

BUGS

Active mode not supported

Error checking assumes a closed socket is normal. No way around this.

Lack of documentation
