twisted.protocols.socks.SOCKSv4

Known subclasses: twisted.test.test_socks.SOCKSv4Driver

An implementation of the SOCKSv4 protocol.

Instance Variable	logging	If not `None`, the name of the logfile to which connection information will be written. (type: `str` or `None`)
Instance Variable	reactor	The reactor used to create connections. (type: object providing `twisted.internet.interfaces.IReactorTCP`)
Instance Variable	buf	Part of a SOCKSv4 connection request. (type: `str`)
Instance Variable	otherConn	Until the connection has been established, `otherConn` is `None`. After that, it is the proxy-to-destination protocol instance along which the client's connection is being forwarded. (type: `SOCKSv4Incoming`, `SOCKSv4Outgoing` or `None`)
Method	__init__	Undocumented
Method	connectionMade	Called when a connection is made.
Method	dataReceived	Called whenever data is received.
Method	connectionLost	Called when the connection is shut down.
Method	authorize	Undocumented
Method	connectClass	Undocumented
Method	listenClass	Undocumented
Method	makeReply	Undocumented
Method	write	Undocumented
Method	log	Undocumented
Method	_dataReceived2	The second half of the SOCKS connection setup. For a SOCKSv4 packet this is after the server address has been extracted from the header. For a SOCKSv4a packet this is after the host name has been resolved.

Inherited from Protocol:

Method

logPrefix

Return a prefix matching the class name, to identify log messages related to this protocol instance.

Inherited from BaseProtocol (via Protocol):

Method

makeConnection

Make a connection to a transport and a server.

logging =

If not None, the name of the logfile to which connection information will be written. (type: str or None)

reactor =

The reactor used to create connections. (type: object providing twisted.internet.interfaces.IReactorTCP)

buf =

Part of a SOCKSv4 connection request. (type: str)

otherConn =

Until the connection has been established, otherConn is None. After that, it is the proxy-to-destination protocol instance along which the client's connection is being forwarded. (type: SOCKSv4Incoming, SOCKSv4Outgoing or None)

def __init__(self, logging=None, reactor=reactor):

Undocumented

def connectionMade(self):

from twisted.internet.interfaces.IProtocol

overrides twisted.internet.protocol.BaseProtocol.connectionMade

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.

def dataReceived(self, data):

from twisted.internet.interfaces.IProtocol

overrides twisted.internet.protocol.Protocol.dataReceived

Called whenever data is received.

Parameters data Part or all of a SOCKSv4 packet. (type: bytes)

def _dataReceived2(self, server, user, version, code, port):

The second half of the SOCKS connection setup. For a SOCKSv4 packet this is after the server address has been extracted from the header. For a SOCKSv4a packet this is after the host name has been resolved.

Parameters	server	The IP address of the destination, represented as a dotted quad. (type: `str`)
	user	The username associated with the connection. (type: `str`)
	version	The SOCKS protocol version number. (type: `int`)
	code	The comand code. 1 means establish a TCP/IP stream connection, and 2 means establish a TCP/IP port binding. (type: `int`)
	port	The port number associated with the connection. (type: `int`)
