[Apache]Redhat 9 CGI error

[Verwijderd]

Ik zit met een vervelend probleem en ik kom er maar niet achter waardoor het veroorzaakt word.

Ik heb een server met RedHat 9 geinstalleerd. Dit is een server voor intern gebruik om php en CGI files te testen in een Apache omgeving. php gaat prima echter met CGI krijg ik continue een error, het maakt niet uit hoe simpel het cgi-scriptje ook is.

Ik heb al via google gezocht en kwam een aantal mogelijke oorzaken tegen, echter geen van de geboden (mogelijke) oplossingen werkt bij mij.

Ik heb een aantal test scriptjes gemaakt om te kijken waar het evt. fout ging, echter ik krijg continue dezelfde nikszeggende melding

HTML:

Server error!

    The server encountered an internal error and was unable to 
complete your request. 

    Error message:
    Premature end of script headers: hello.cgi 

    If you think this is a server error, please contact the webmaster 

Error 500

Ik weet dat het pad goed staat in het scriptje, de rechten van de directory en het script staan goed (755), perl is geinstalleerd mod_cgi is geinstalleerd. En in de httpd.conf kan ik ook niks raars ontdekken

Wie o wie kan mij helpen (ook in de error_log van apache staat niks bijzonders)

hier is mijn apache conf.

Kijk eens in de logfiles van apache

Zo te zien gaat er iets fout bij de headers versturen.
Probeer hetvolgende C++ proggie eens, dat werkt i.i.g.

C++:

#include <iostream>
using namespace std;

int main()
{
   cout << "Content-Type: text/html" << endl << endl;
   cout << "<b>Testje</b>" << endl;

   return 0;
}

Compileren met g++ -Wall testje.cpp -o testje

ok gedaan moto (uitgevoerd via console) en ik krijg idd uitvoer te zien in de console. Wat ik nog vergeten was te vertellen is dat als ik de cgi scripts uitvoer via de console het wel lukt, ik krijg dan allemaal html output the zien in de console (dus wat je normaal in je browser zou moeten zien).

Ja.. leuk voor je, maar werkt dat c++ programma wat ik gaf ook via je browser ?

Ik had namelijk precies hetzelfde probleem als jou, aangezien ik vergeten wat een lege regel na de header te geven

Verder valt er weinig over te zeggen, zonder je logfiles entries enzo..

[Verwijderd]

yup je c++ progje doet het ook via de browser echter zoals ik al zei over de logfiles daar staat dus niks in waar je hier iets aan hebt, de error melding m.b.t. de cgi files is hetzelfde als wat je krijgt te zien in je browser, nl. dit dus:

code:

[Mon Sep 15 14:20:28 2003] [error] [client 192.168.10.242] 
Premature end of script headers: hello.cgi
[Mon Sep 15 14:20:46 2003] [error] [client 192.168.10.242] 
Premature end of script headers: hello.cgi

OK, volgende stap : strip die hello.cgi tot het meest minimale, probeer het dan te draaien, mocht het niet werken : Laat de source -code hier eens zien (graag tussen [code=perl] [/code] of [code=c] [/code] zetten )

maximaal gestript:

Perl:

#!/usr/bin/perl

exit;

Je moet in CGI in elk geval een content type meegeven, bijv. "Content-Type: text/html", met daarachter 2 keer een "end of line"

Zo doet hij het dus wel..
Je was de lege regels na de header vergeten.
