t.p.f.FTP(object, basic.LineReceiver, policies.TimeoutMixin) : class documentation

Called when a connection is made.

This may be considered the initializer of the protocol, because it is called when the connection is completed. For clients, this is called once the connection to the server has been established; for servers, this is called after an accept() call stops blocking and a socket has been received. If you need to send any greeting or initial message, do it here.

Called when the connection is shut down.

Clear any circular references here, and any external references to this Protocol. The connection has been closed.

Called when the connection times out.

Override to define behavior other than dropping the connection.

Override this for when each line is received.

Parameters

line

The line which was received with the delimiter removed. (type: str)

Return a port for passive access, using self.passivePortRange attribute.

First part of login. Get the username the peer wants to authenticate as.

Second part of login. Get the password the peer wants to authenticate with.

Request for a passive connection

from the rfc:

   This command requests the server-DTP to "listen" on a data port
   (which is not its default data port) and to wait for a connection
   rather than initiate one upon receipt of a transfer command.  The
   response to this command includes the host and port address this
   server is listening on.

This command causes a list to be sent from the server to the passive DTP. If the pathname specifies a directory or other group of files, the server should transfer a list of files in the specified directory. If the pathname specifies a file then the server should send current information on the file. A null argument implies the user's current working or default directory.

This command causes a directory listing to be sent from the server to the client. The pathname should specify a directory or other system-specific file group descriptor. An empty path implies the current working directory. If the path is non-existent, send nothing. If the path is to a file, send only the file name.

Parameters	path	The path for which a directory listing should be returned. (type: str)
Returns	a Deferred which will be fired when the listing request is finished. (type: Deferred)

This command causes the content of a file to be sent over the data transfer channel. If the path is to a folder, an error will be raised.

Parameters	path	The path to the file which should be transferred over the data transfer channel. (type: str)
Returns	a Deferred which will be fired when the transfer is done. (type: Deferred)

call when DTP connection exits
