A packet parsing and manipulation library for the SMB2 protocol.
See Microsoft's [MS-SMB2]
It supports authentication via NTLM using the ruby ntlm gem
This gem has not yet been released, but when it is, do this:
Add this line to your application's Gemfile:
gem 'smb2'And then execute:
$ bundle
Or install it yourself as:
$ gem install smb2
dispatcher = Smb2::Dispatcher::Socket.connect("192.168.100.140", 445)
client = Smb2::Client.new(
dispatcher: dispatcher,
username:"administrator",
password:"P@ssword1",
domain:"asdfasdf"
)
client.negotiate
client.authenticate
tree = client.tree_connect("\\\\#{dispatcher.socket.remote_address.ip_address}\\Users")Now you can open files on the connected share. Tree#create is intended
to behave like Ruby's
File.open:
# read/write by default
file = tree.create("Public\\file.txt")
file.read # => <full contents of file.txt>
file.write("\nAppend a new line to file.txt")Or with a block, the file will be closed when the block returns:
data = tree.create("Public\\file.txt") { |file|
file.read
}sock = TCPSocket.new("192.168.100.140", 445)
neg = Smb2::Packet::NegotiateRequest.new(
# This is necessary until I can figure out how to set a default for
# `rest` fields
dialects: "\x02\x02".force_encoding("binary"),
)
nbss = [neg.length].pack("N")
sock.write(nbss + neg.to_s)
# Grab NBSS size
size = sock.read(4).unpack("N").first
data = sock.read(size)
neg_response = Smb2::Packet::NegotiateResponse.new(data)Smb2 is released under a 3-clause BSD license. See LICENSE.txt for full text.
