Here's the code I'm playing with. Note that it is broken and has many
problems including not correctly reading the messages received. But it
will give you an idea on how things could work...
import sys
import os
import socket
import struct
msg_error = 0
msg_nop = 1
msg_read = 2
msg_write = 3
msg_dir = 4
msg_size = 5
msg_presence = 6
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
print s
s.connect(('kuro2', 9999))
payload = '/'
#payload = '/bus.0'
#payload='/10.B7B64D000800'
print 'payload:', payload
smsg = struct.pack('iiiiii',
socket.htonl(0), #version
socket.htonl(len(payload) + 1), #payload length
socket.htonl(msg_dir), #type of function call
socket.htonl(258), #format flags
socket.htonl(0), #size of data element for read or write
socket.htonl(0), #offset for read or write
)
print 'len(smsg):', len(smsg)
print 'smsg:', smsg
s.sendall(smsg)
smsg = payload + '\x00'
print 'len(smsg):', len(smsg)
print 'smsg:', smsg
s.sendall(smsg)
log = open('/tmp/ow.log', 'w')
data = s.recv(24)
print
print 'len(data):', len(data)
print 'data:', data
try:
data1 = s.recv(67)
data = data + data1
data2 = ' '
while len(data2):
data2 = s.recv(67)
data = data + data2
except socket.error:
pass
log.write(data)
log.close()
s.close()
print
print 'len(data):', len(data)
print 'data:', data
#version, payload_len, type_of_call, format_flags, size_of_data,
offset, payload = struct.unpack('iiiiiis', data)
version, payload_len, type_of_call, format_flags, size_of_data, offset
= struct.unpack('iiiiii', data[:24])
version = socket.ntohl(version)
payload_len = socket.ntohl(payload_len)
type_of_call = socket.ntohl(type_of_call)
format_flags = socket.ntohl(format_flags)
size_of_data = socket.ntohl(size_of_data)
offset = socket.ntohl(offset)
print
print 'version:', version
print 'payload_len:', payload_len
print 'type_of_call:', type_of_call
print 'format_flags:', format_flags
print 'size_of_data:', size_of_data
print 'offset:', offset
if payload_len:
print 'payload:', data1
for idx in range(0, len(data1)):
print idx, ord(data1[idx]), data1[idx]
sys.exit(0)
