IIS6 cgi (exe) issues

#1 08-06-2008, 09:12 AM

Greetings --

I am having trouble getting an application set up on IIS 6 properly.
I have created a website with a virtual directory. The virtual
directory is set to "Scripts and Executables" for execute permissions
(the files are .exe).

There is no MIME type set for .exe. There is no mapping that I can
tell. I have set a web service extension up for these files (I even
set to "Allow All Unknown CGI").

Yet when I try to access the page (IE7) I get a blank page. Here is
the output of a test script:

HTTP/1.1 200 OK
Connection: Close
Content-Length: 101
Content-Type: text/html; charset=ISO-8859-1

<html>

<head>
<title>Test Page</test>
</head>

<body>

<h2>Testing...</h2>

</body>
</html>

Any suggestions????

Is the CGI EXE launched by IIS via a request, or launched by your test
script?
- If it is the former, then please provide the exact response, in
bytes. The vdir requires "Scripts and Executables"
- If it is the latter, then please indicate how your test script is
capturing the EXE output and then stream it as a response. The vdir
only requires "Scripts"

David -- You are everywhere! Thanks for keeping up with me, I'm just
trying to get this resolved by any way possible. I'll have the byte
response momentarily, but first I wanted to post something I captured
using FileMonitor (part of the MS System Internals suite of apps).

333 10:00:41 AM w3wp.exe:1920 OPEN C:\Program Files\Key Systems\GFMS
\exe\test_IIS.exe SUCCESS Options: Open Access: 001000A1
334 10:00:41 AM w3wp.exe:1920 READ C:\WINDOWS\system32\config\system

\exe\test_IIS.exe SUCCESS

You can see where IIS tries to grab a file called
"test_IIS.exe.Config" -- could this be the problem? Why is it looking
for that file?

Thanks!

And here is what I'm getting back from IIS:

HTTP/1.1 200 OK
Server: Microsoft-IIS/6.0
Panic: Can't create C:\WINDOWS\TEMP\pdk-IUSR_ENGIN-SERVER
\5f4010392d26de2972604a5df777f946\perl58.dll
X-Powered-By: ASP.NET
Date: Thu, 07 Aug 2008 14:40:40 GMT
Connection: close

So yes, this appears to be an issue related to this specific
application (which is a compiled perl script) -- but I don't
understand why, on the same server, it executes in Apache2.x/IIS5, but
not IIS6?

Thanks for all of your help!

Well, I managed to resolved the strange perl58.dll error by deleting
the existing file. Once that happened (it must have been a
permissions issue with that file) I no longer get that error.

Now I get the 502 Error from IIS along with the "Incomplete HTTP
Headers" message.

The problem continues to be your CGI script and its invalid
assumptions of a proper HTTP response that a CGI should generate.

It may run on Apache 2 or IIS5, but it hardly means it is correct.
Maybe those web servers have looser security checks and requirements
of CGI/1.1 specification...
