Hi Arno,

I went back over everything you provided for me and I finally got it! I have
it working now.

Thanks so much,

Hi Francois,

Thanks very much for your offer. I'd like very much to see your
proxy/tunnel.
Please email it to me.

 Subject: Re: [twsocket] NNTP / SMTP / POP3 proxy/tunnel
 
  I want to build a simple NNTP proxy. However, I only need to
 intercept the
  POST command and then grab the message. I've done this and I've found
 it
  easy to accomplish. Do you think this slight variation of socketspy
 is
  actually useable, or do I need a more robust proxy? I was unable to
 find a
  NNTP proxy in Delphi/Cbuilder anywhere. I do like the simplicity of
  socketspy. I could build on it if I should need more in the future.
 
 I wrote a SMTP/POP3 proxy server with HTTP tunnelling. You could use
 similar
 code in your NNTP proxy. Initially I wanted to implement NNTP the same
 way
 but had no time to do it yet.
 
 The goal of my application (OverbyteGateway and OverbyteGatewayServer
 as I
 named the beast) is to allow someone to use standard SMTP/POP3 client
 such
 as Windows Mail Client within an organization where only HTTP is
 allowed
 with the help of a second program running on another computer. Any
 computer
 or server is OK. I even use a dynamic IP by the way of DynDNS service.
 
 Instead of starting from SocketSpy I started at a higher level. I mean,
 SocketSpy works at the TCP level, not knowing anything about what is
 transported while the code I wrote understand SMTP and POP3 commands.
 This
 makes things easier as soon as you must intercept some specific
 command.
 
 When I said understand SMTP and POP3 commands, I don't mean complete
 command implementation. Since my proxy is mainly a tunnel, one side of
 the
 tunnel (client side) listen for POP3/SMTP commands, roughly decode it,
 encapsulate it into a HTTP request, send the the server side which in
 turn
 send it to the actual external SMTP/POP3 server. The code was fairly
 easy to
 write. Actually I implemented only the commands used by Windows Mail
 Client
 which I use. Other client program could require other commands altough
 it is
 likely not.
 
 I have not yet had time to publish this code. It probably need some
 cleaning
 and some commenting. Anyway, if you or someone else want it, I can
 build a
 zip file and email it. No waranty and no commitment to support it
 altough I
 will do my best to answer questions in twsocket mailing list. The
 license is
 almost the same as TWSocket: you can use it freely for whatever legal
 you
 want but you cannot claim you wrote the code. You must include a notice
 in
 your software (source code, about box and documentation) that you used
 my
 code, with clear reference to me and my website.
 
 And by the way, you can buy consulting or custom developement from me
 if you
 want me to customize that code for you, or private email support if you
 don't want to talk in public about your project. Email me for prices.

 Subject: Re: [twsocket] SocketSpy to C++ Problem

 Richard,

  I was looking over my project and see that the processmessages loop I
  said allows the program to complete successfully is enabled. To allow
  the error this needs to be commented out. It's at the end of
  WSocketServerClientConnect.

 I removed these lines.
 However it works (basically) with the changes posted in my previous
 message with latest ICSv7 and C++ Builder 2007.

I'm not sure which changes you refer to. Do you mean not sending a banner?
I've looked at the archives in case I missed a message. It looks like I
didn't, but I'm not sure what you're referring to. I think I've somehow
missed something.

 Tested with NNTP and HTTP (8 local clients). But since you use
 LineMode there's a problem with binary data because DataAvailable
 might not trigger when LineEnd is not received. Use LineMode only
 if the protocol is 100% line-based.

My purpose for translating socketspy was to just get it working in C++. My
intentions are to create a component that does what socketspy does, but it
will be used strictly with NNTP. Sorry I didn't mention that. I know the
logging to a richedit dramatically slows the redirection. That's just for
testing.

I want to build a simple NNTP proxy. However, I only need to intercept the
POST command and then grab the message. I've done this and I've found it
easy to accomplish. Do you think this slight variation of socketspy is
actually useable, or do I need a more robust proxy? I was unable to find a
NNTP proxy in Delphi/Cbuilder anywhere. I do like the simplicity of
socketspy. I could build on it if I should need more in the future.

 There's also a bug with shutting down the local client.
 After a call to ShutDown(1) it is no longer allowed to send data,
 however there might be still data in component's send buffer, so
 in order to avoid a socket exception and to make sure the local
 client gets everything add a flag to your client class and handle
 event OnDataSent, something like:

Thanks so much for this info, I'll sure fix that immediately.

Richard

 void __fastcall TSocketWin::ClientDataSent(TObject *Sender, WORD
 ErrCode)
 {
   [..]
   if (client-closeflag)
   client-Shutdown(1);
 }

 and

 void __fastcall TSocketWin::RemoteSessionClosed(TObject *Sender, WORD
 Error)
 {
[..]
if (client-AllSent)
client-Shutdown(1);
else
client-closeflag = true;
 }

[twsocket] SocketSpy to C++ Problem

2011-01-22 Thread Richard Christman

Hi All,

My apologies. When the list sent my message to me, there was no attachment.
I'm going to try again in case I screwed this up. If it arrives without it
please tell me how I'm to include my project. 



I have done a cbuilder translation of Mr. Mestdagh's SpocketSpy program.
But, I have a problem. When I run the program and try to connect with a
server, I get this immediate error:

An unknown response was received in response to a request for information
from the news server 'SocketSpyC++ Local TCP Proxy'

Under the details button of the error dialog, I get:

SocketSpyC++ Local TCP Proxy

Configuration:
   Account: SocketSpyC++ Local TCP Proxy
   Server: 127.0.0.1
   Protocol: NNTP
   Port: 119
   Secure(SSL): 0
   Code: 800ccca0

I don't have any idea what the problem is. First, while trying to debug, I
put a popup messagebox at the end of the WSocketServerClientConnect
procedure to take a look at a variable. What I discovered was that
messagebox being open allowed the program to actually connect and go further
before error. After that, I replaced the messagebox with an
Application-ProcessMessages() loop as a test. I was amazed that after that,
the program ran completely and reliably--everytime. It works just great, but
I haven't tried more than 1 connection because of the ProcessMessages loop. 
Though the loop has been helpful, I doubt it is the appropriate fix for
this.

My socketspyc project is attached. Please have a look. The ProcessMessages
loop is at the end of the WSocketServerClientConnect procedure.

Richard Christman

Hi Arno,

I took out the banner and still the error. I took out banner and
bannertoobusy (individually and both together) and neither made difference.

I also commented out all logging last week and no difference from that
either.

 Do not send a server banner:
 
 void __fastcall TSocketWin::ListenBtnClick(TObject *Sender)
 {
if (ListenBtn-Tag == 0)
{
NNTPLog-Clear();
   WSocketServer-Banner = ; //== !
 
 
 Make sure this one doesn't AV :
 void __fastcall TSocketWin::Log(AnsiString Msg)
 {
while (Msg.Length()  (Msg[Msg.Length()] == '\n' ||
 Msg[Msg.Length()] == '\r'))
Msg.Delete(Msg.Length(), 1);
log-Add(Msg);
