RE: Proxomitron reduces RWIN to 32768
Sorry the review took us so long.
But I think most people will understand.

Patches are at

http:// rapidshare.de/files/8168374/N45RWIN.zip.html


Evidently rapidshare.de changed the 45 day policy and deleted the file.

For now, N45RWIN.zip has been uploaded to

N45RWIN.zip ReadMe is:
Quote:***********************The Problem*******************************************
If you are reading this then you probably know that Proxomitron can set RWIN to 32768.
http://prxbx.com/forums/viewtopic.php?t=641
http://groups.yahoo.com/group/prox-list/message/22257

To test your Operating System, go to http://www.speedguide.net/analyzer.php
Check the value of RWIN, with and without using Proxomitron.

Windows XP SP2 or Server 2003 with Proxomitron probably show 32768.
Windows 95, 98, 98SE, or 2000 with Proxomitron probably do not.
When Proxomitron uses another local proxy like
Browser -->Proxomitron-->Proxy-->ISP
the "correct" RWIN is probably shown.

***********************The Patches*******************************************
There are patches that may return control of RWIN to Windows at
http://wind.prohosting.com/proxmine/cgi-bin/uploader/ .
Our Japanese friends have been using them for approximately a year.
A translation of the ReadMe in PmU_0341.zip is below.

N45jRWIN.exe and N45mRWIN.exe use the same method the Japanese patches use.
They also add a disclaimer to Proxomitron's "About" screen.

To install a patch:
Make a backup copy of the Proxomitron exe.
Execute N45jRWIN.exe to alter the *June* version of Proxomitron Naoko 4.5.
Execute N45mRWIN.exe to alter the *May* version of Proxomitron Naoko 4.5.
Visit the "About" screen and verify the info.

Report problems caused by the patch to your favorite Proxomitron forum or the Prox-List.

I read the readme.txt and checked the referred article on a Japanese BBS.
They said it fixes the RWIN limit.
http://web.archive.org/web/2004113021481...092672987/

This is the patched address...

*Naoko 4.5 June
FILENAME Proxomitron.exe
0000D581: 04

*Naoko 4.5 May
FILENAME Proxomitron.exe
0000D521: 04

In detail they said this patch changes the argument of SetSockOpt.
Original Proxomitron uses this value...
nOptionLen : 04

And this patch changes...
nOptionLen : 00

I am not programmer so I don't know what that means.

> Can it be used on the original exe?

Yes. But the exe filename should be "Proxomitron.exe"

> Who is the author?

That is anonymous BBS so I can't find out who the author is.

Thanks,
count_b
[/Letter]

The SetSockOpt command can be used to set the "receive window size" on a per-socket basis.
For reasons still unknown, the command does that on some but not all Windows systems.
Setting nOptionLen to 0 nullifies the socket option and returns control of RWIN to Windows.

***********************A Request*********************************************
Everybody should be very careful. Proxomitron is not our program.
If a patched exe got loose and caused trouble, Scott would likely catch the blame.
Do not share or distribute patched EXEs.
