XEP-0065: SOCKS5 Bytestreams#

class slixmpp.plugins.xep_0065.XEP_0065(xmpp, config=None)[source]#

activate(proxy, sid, target, ifrom=None, timeout=None, callback=None)[source]#: Activate the socks5 session that has been negotiated.

close()[source]#: Closes all proxy sockets.

deactivate(sid)[source]#: Closes the proxy socket associated with this SID.

default_config: ClassVar[Dict[str, Any]] = {'auto_accept': False}#: The basic, standard configuration for the plugin, which may be overridden when initializing the plugin. The configuration fields included here may be accessed directly as attributes of the plugin. For example, including the configuration field ‘foo’ would mean accessing plugin.foo returns the current value of plugin.config[‘foo’].

dependencies: ClassVar[Set[str]] = {'xep_0030'}#: Some plugins may depend on others in order to function properly. Any plugin names included in dependencies will be initialized as needed if this plugin is enabled.

description: str = 'XEP-0065: SOCKS5 Bytestreams'#: A longer name for the plugin, describing its purpose. For example, a plugin for XEP-0030 would use ‘Service Discovery’ as its description value.

async discover_proxies(jid=None, ifrom=None, timeout=None)[source]#: Auto-discover the JIDs of SOCKS5 proxies on an XMPP server.

get_network_address(proxy, ifrom=None, timeout=None, callback=None)[source]#: Get the network information of a proxy.

get_socket(sid)[source]#: Returns the socket associated to the SID.

async handshake(to, ifrom=None, sid=None, timeout=None)[source]#: Starts the handshake to establish the socks5 bytestreams connection.

name: str = 'xep_0065'#: A short name for the plugin based on the implemented specification. For example, a plugin for XEP-0030 would use ‘xep_0030’.

Internal API methods#

The internal API is used here to authorize or pre-authorize streams.

authorized_sid (0065 version)#

jid: JID receiving the stream initiation.
node: stream id
ifrom: who the stream is from.
args: Iq of the stream request.
returns: True if the stream should be accepted, False otherwise.

Check if the stream should be accepted. Uses the information setup by preauthorize_sid (0065 version) by default.

authorized (0065 version)#

jid: JID receiving the stream initiation.
node: stream id
ifrom: who the stream is from.
args: Iq of the stream request.
returns: True if the stream should be accepted, False otherwise.

A fallback handler (run after authorized_sid (0065 version)) to check if a stream should be accepted. Uses the auto_accept parameter by default.

preauthorize_sid (0065 version)#

jid: JID receiving the stream initiation.
node: stream id
ifrom: who the stream will be from.
args: Unused.

Stanza elements#

class slixmpp.plugins.xep_0065.stanza.Socks5(xml=None, parent=None)[source]#

add_streamhost(jid, host, port)[source]#

interfaces: ClassVar[Set[str]] = {'activate', 'sid'}#: The set of keys that the stanza provides for accessing and manipulating the underlying XML object. This set may be augmented with the plugin_attrib value of any registered stanza plugins.

name: ClassVar[str] = 'query'#: The XML tag name of the element, not including any namespace prefixes. For example, an ElementBase object for <message /> would use name = 'message'.

namespace: str = 'http://jabber.org/protocol/bytestreams'#: The XML namespace for the element. Given <foo xmlns="bar" />, then namespace = "bar" should be used. The default namespace is jabber:client since this is being used in an XMPP library.

plugin_attrib: ClassVar[str] = 'socks'#

For ElementBase subclasses which are intended to be used as plugins, the plugin_attrib value defines the plugin name. Plugins may be accessed by using the plugin_attrib value as the interface. An example using plugin_attrib = 'foo':

register_stanza_plugin(Message, FooPlugin)
msg = Message()
msg['foo']['an_interface_from_the_foo_plugin']

plugin_attrib_map: ClassVar[Dict[str, Type[ElementBase]]] = {'streamhost': <class 'slixmpp.plugins.xep_0065.stanza.StreamHost'>, 'streamhost_used': <class 'slixmpp.plugins.xep_0065.stanza.StreamHostUsed'>, 'streamhosts': <class 'slixmpp.xmlstream.stanzabase.multifactory.<locals>.Multi'>}#: A mapping of the plugin_attrib values of registered plugins to their respective classes.

plugin_iterables: ClassVar[Set[Type[ElementBase]]] = {<class 'slixmpp.plugins.xep_0065.stanza.StreamHost'>}#

The set of stanza classes that can be iterated over using the ‘substanzas’ interface. Classes are added to this set when registering a plugin with iterable=True:

register_stanza_plugin(DiscoInfo, DiscoItem, iterable=True)

New in version 1.0-Beta5.

plugin_overrides: ClassVar[Dict[str, str]] = {}#

A map of interface operations to the overriding functions. For example, after overriding the set operation for the interface body, plugin_overrides would be:

{'set_body': <some function>}

plugin_tag_map: ClassVar[Dict[str, Type[ElementBase]]] = {'{http://jabber.org/protocol/bytestreams}streamhost': <class 'slixmpp.plugins.xep_0065.stanza.StreamHost'>, '{http://jabber.org/protocol/bytestreams}streamhost-used': <class 'slixmpp.plugins.xep_0065.stanza.StreamHostUsed'>, '{jabber:client}stanza': <class 'slixmpp.xmlstream.stanzabase.multifactory.<locals>.Multi'>}#: A mapping of root element tag names (in '{namespace}elementname' format) to the plugin classes responsible for them.

sub_interfaces: ClassVar[Set[str]] = {'activate'}#: A subset of interfaces which maps interfaces to direct subelements of the underlying XML object. Using this set, the text of these subelements may be set, retrieved, or removed without needing to define custom methods.

class slixmpp.plugins.xep_0065.stanza.StreamHost(xml=None, parent=None)[source]#

get_jid()[source]#

interfaces: ClassVar[Set[str]] = {'host', 'jid', 'port'}#: The set of keys that the stanza provides for accessing and manipulating the underlying XML object. This set may be augmented with the plugin_attrib value of any registered stanza plugins.

name: ClassVar[str] = 'streamhost'#: The XML tag name of the element, not including any namespace prefixes. For example, an ElementBase object for <message /> would use name = 'message'.

namespace: str = 'http://jabber.org/protocol/bytestreams'#: The XML namespace for the element. Given <foo xmlns="bar" />, then namespace = "bar" should be used. The default namespace is jabber:client since this is being used in an XMPP library.

plugin_attrib: ClassVar[str] = 'streamhost'#

register_stanza_plugin(Message, FooPlugin)
msg = Message()
msg['foo']['an_interface_from_the_foo_plugin']

plugin_multi_attrib: ClassVar[str] = 'streamhosts'#

For ElementBase subclasses that are intended to be an iterable group of items, the plugin_multi_attrib value defines an interface for the parent stanza which returns the entire group of matching substanzas. So the following are equivalent:

# Given stanza class Foo, with plugin_multi_attrib = 'foos'
parent['foos']
filter(isinstance(item, Foo), parent['substanzas'])

set_jid(value)[source]#

class slixmpp.plugins.xep_0065.stanza.StreamHostUsed(xml=None, parent=None)[source]#

get_jid()[source]#

interfaces: ClassVar[Set[str]] = {'jid'}#: The set of keys that the stanza provides for accessing and manipulating the underlying XML object. This set may be augmented with the plugin_attrib value of any registered stanza plugins.

name: ClassVar[str] = 'streamhost-used'#: The XML tag name of the element, not including any namespace prefixes. For example, an ElementBase object for <message /> would use name = 'message'.

namespace: str = 'http://jabber.org/protocol/bytestreams'#: The XML namespace for the element. Given <foo xmlns="bar" />, then namespace = "bar" should be used. The default namespace is jabber:client since this is being used in an XMPP library.

plugin_attrib: ClassVar[str] = 'streamhost_used'#

register_stanza_plugin(Message, FooPlugin)
msg = Message()
msg['foo']['an_interface_from_the_foo_plugin']

set_jid(value)[source]#
