pybitmessage.network.tcp module¶
src/network/tcp.py¶
-
class
Socks4aBMConnection(address)[source]¶ Bases:
network.socks4a.Socks4aConnection,pybitmessage.network.tcp.TCPConnectionSOCKS4a wrapper for TCP connections
-
state_proxy_handshake_done()¶ State when SOCKS4a connection succeeds, we need to send a Bitmessage handshake to peer.
-
-
class
Socks5BMConnection(address)[source]¶ Bases:
network.socks5.Socks5Connection,pybitmessage.network.tcp.TCPConnectionSOCKS5 wrapper for TCP connections
-
state_proxy_handshake_done()¶ State when SOCKS5 connection succeeds, we need to send a Bitmessage handshake to peer.
-
-
class
TCPConnection(address=None, sock=None)[source]¶ Bases:
network.bmproto.BMProto,network.tls.TLSDispatcherTodo
Look to understand and/or fix the non-parent-init-called
-
antiIntersectionDelay(initial=False)¶ This is a defense against the so called intersection attacks.
It is called when you notice peer is requesting non-existing objects, or right after the connection is established. It will estimate how long an object will take to propagate across the network, and skip processing “getdata” requests until then. This means an attacker only has one shot per IP to perform the attack.
-
handle_close()¶ Callback for connection being closed.
-
handle_connect()¶ Callback for TCP connection being established.
-
handle_read()¶ Callback for reading from a socket
-
handle_write()¶ Callback for writing to a socket
-
sendAddr()¶ Send a partial list of known addresses to peer.
-
sendBigInv()¶ Send hashes of all inventory objects, chunked as the protocol has a per-command limit.
-
set_connection_fully_established()¶ Initiate inventory synchronisation.
-
state_connection_fully_established()¶ State after the bitmessage protocol handshake is completed (version/verack exchange, and if both side support TLS, the TLS handshake as well).
