1.
Yes! I myself noticed that, but your 2nd version looks
a bit more verbose.
2.
This all means... what? ONLY send() vs sendall() matters?
Sometimes send() really sends ALL and my version works too!
I must give it a thorough testing!
3.
See how it looks in SQL Server Profiler (it's its utility for
tracing client/server events) WHEN I started 5 copies of .vbs.

Btw, without s2.shutdown(1) those vbs' do NOT disconnect from
the server (see DISCONNECT events on the gif).
The latest python version:
==============================
import socket, thread
sqls_host, sqls_port = '127.0.0.1', 1433
proxy_host, proxy_port = '127.0.0.1', 1434
# How I tested it:
# sqls_host, sqls_port = 'www.google.com', 80
def VB_SCRIPT(s2, cn):
while 1:
data = cn.recv(4096)
if not data:
s2.shutdown(1)
return
s2.sendall(data)
print 'VB_SCRIPT:' + data + '\n'
def SQL_SERVER(s2, cn):
while 1:
data = s2.recv(4096)
if not data: return
cn.sendall(data)
print 'SQL_SERVER:' + data + '\n'
s1 = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s1.bind((proxy_host, proxy_port))
s1.listen(5)
while 1:
cn, addr = s1.accept()
s2 = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s2.connect((sqls_host, sqls_port))
thread.start_new_thread(VB_SCRIPT,(s2, cn))
thread.start_new_thread(SQL_SERVER,(s2, cn))
The vbs text:
==============
Set cn = CreateObject("ADODB.Connection")
cn.Open _
"Provider=sqloledb;Data Source=127.0.0.1,1434;" & _
"Network Library=DBMSSOCN;Initial Catalog=pubs;" & _
"User ID=qwe;Password=asdasd;"
cn.Execute _
"select 'AAAAAAAAAAAAAAA';" & _
"waitfor delay '00:00:02'; raiserror('XXX',10,1) with nowait;" & _
"waitfor delay '00:00:02'; raiserror('YYY',10,1) with nowait;" & _
"waitfor delay '00:00:02'; raiserror('ZZZ',10,1) with nowait;" & _
"select 'BBBBBBBBBBBBBBB';"
cn.Close
Set cn = Nothing
