twisted.pair.tuntap.TuntapPort

Implements interfaces: twisted.internet.interfaces.IListeningPort

A Port that reads and writes packets from/to a TUN/TAP-device.

Method	__init__
Method	__repr__	Undocumented
Method	startListening	Create and bind my socket, and begin listening on it.
Method	fileno	File Descriptor number for select().
Method	doRead	Called when my socket is ready for reading.
Method	write	Write the given data as a single datagram.
Method	writeSequence	Write a datagram constructed from a `list` of `bytes`.
Method	stopListening	Stop accepting connections on this port.
Method	loseConnection	Close this tunnel. Use `TuntapPort.stopListening` instead.
Method	connectionLost	Cleans up my socket.
Method	logPrefix	Returns the name of my class, to prefix log entries with.
Method	getHost	Get the local address of this `TuntapPort`.
Method	_openTunnel	Open the named tunnel using the given mode.
Method	_bindSocket	Open the tunnel.

Inherited from FileDescriptor:

Method	writeSomeData	Write as much as possible of the given data, immediately.
Method	doWrite	Called when data can be written.
Method	writeConnectionLost	Indicates write connection was lost.
Method	readConnectionLost	Indicates read connection was lost.
Method	loseWriteConnection	Undocumented
Method	stopReading	Stop waiting for read availability.
Method	stopWriting	Stop waiting for write availability.
Method	startReading	Start waiting for read availability.
Method	startWriting	Start waiting for write availability.
Method	stopConsuming	Stop consuming data.
Method	resumeProducing	Resume producing data.
Method	pauseProducing	Pause producing data.
Method	stopProducing	Stop producing data.
Method	_postLoseConnection	Called after a loseConnection(), when all data has been written.
Method	_closeWriteConnection	Undocumented
Method	_isSendBufferFull	Determine whether the user-space send buffer for this transport is full or not.
Method	_maybePauseProducer	Possibly pause a producer, if there is one and the send buffer is full.

Inherited from _ConsumerMixin (via FileDescriptor):

Instance Variable	producer	`None` if no producer is registered, otherwise the registered producer.
Instance Variable	producerPaused	A flag indicating whether the producer is currently paused. (type: `bool`)
Instance Variable	streamingProducer 0	A flag indicating whether the producer was registered as a streaming (ie push) producer or not (ie a pull producer). This will determine whether the consumer may ever need to pause and resume it, or if it can merely call `resumeProducing` on it when buffer space is available.
Instance Variable	streamingProducer	`bool` or `int`
Method	registerProducer	Register to receive data from a producer.
Method	unregisterProducer	Stop consuming data from a producer, without disconnecting.

Inherited from _LogOwner (via FileDescriptor):

Method _getLogPrefix Determine the log prefix to use for messages related to applicationObject, which may or may not be an interfaces.ILoggingContext provider.

def __init__(self, interface, proto, maxPacketSize=8192, reactor=None, system=None):

overrides twisted.internet.abstract.FileDescriptor.__init__

Parameters reactor An IReactorFDSet provider which this descriptor will use to get readable and writeable event notifications. If no value is given, the global reactor will be used.

def __repr__(self):

Undocumented

def startListening(self):

from twisted.internet.interfaces.IListeningPort

Create and bind my socket, and begin listening on it.

This must be called after creating a server to begin listening on the specified tunnel.

def _openTunnel(self, name, mode):

Open the named tunnel using the given mode.

Parameters	name	The name of the tunnel to open. (type: `bytes`)
	mode	Flags from `TunnelFlags` with exactly one of `TunnelFlags.IFF_TUN` or `TunnelFlags.IFF_TAP` set.
Returns	A `_TunnelDescription` representing the newly opened tunnel.
