Fixes Bitmessage#373
Fixes Bitmessage#79
Fixes#4
Needs to be turned on in the config file (keys.dat) by adding "upnp =
true" into the main section
It needs some cleanup (e.g. if you have multiple routers, it will not
correctly handle failure of one of them)
Python < 2.7.9 does not support anonymous SSL server through
ssl.wrap_socket, so we have to disable it. Works fine as client.
Try to prefer secp256k1 curve (again, requires python >= 2.7.9)
Added global variable Header - a compiled Struct to pack/unpack headers so as to avoid repeatedly compiling the same format string
Add a new method CreatePacket to simply and efficiently construct a packet that is ready to be sent
Modify assembleVersionMessage to use CreatePacket
It will now listen on an IPv6 socket if possible or fall back to IPv4
if that doesn't work. It will no longer filter out all IPv6 addresses
and instead it will only filter out those that point to the local
network.
It looks like the DNS bootstrapping should just automatically work
because getaddrinfo already returns IPv6 addresses from the AAAA
record.
In order to convert from the ASCII representation of IPv6 addresses
and back we need inet_ntop and inet_pton. Python 2 doesn't currently
provide these for Windows so instead this patch provides a hot patch
to the socket module which wraps WSAStringToAddress and
WSAAddressToString using ctypes.
If this option is specified in keys.dat then Bitmessage will connect
to the host specified there instead of connecting to the hosts in the
list of known nodes. It will also stop listening for incoming
connections and the timing attack mitigation will be disabled.
The expected use case is for example where a user is running a daemon
on a dedicated machine in their local network and they occasionally
want to check for messages using a second instance of the client on
their laptop. In that case it would be much faster to catch up with
the messages by directly downloading from the dedicated machine over
the LAN. There is no need to connect to multiple peers or to do the
timing attack mitigation because the daemon is trusted.
The host is specified as hostname:port. Eg, ‘192.168.1.8:8444’.
