alright...i know this is not game related but i need some help concerning perl basically i''m trying to get my perl script to post some text to and html file, when i access it from command line, it works, but when i have it executed through the web it doesnt work (i''m running slackware 9.1, kernel 2.6.4, apache, 1.3.29) this is my code:

#!/usr/bin/perl -w
#
require "cgi-lib.pl";

&ReadParse (*input);

$file=''/usr/local/apache/htdocs/index.html'';
open(INFO, ">>$file");

print INFO ''<table cellspacing="1" cellpadding="5" border="0" bgcolor="#000000"
print INFO ''<tr bgcolor="#EEEEEE" ><td height="130" width="100" align="center"

print INFO ''<td rowspan="2" width="870"  valign="top" >'';
$sFormInput = $input{''TextPost''};
print INFO $sFormInput;
print INFO ''</table>'';
print INFO ''
'';

close(INFO);
 

this is my error log entry when i have it run through the web: print() on closed filehandle INFO at /usr/local/apache/cgi-bin/newpost.pl line 10 print() on closed filehandle INFO at /usr/local/apache/cgi-bin/newpost.pl line 11 print() on closed filehandle INFO at /usr/local/apache/cgi-bin/newpost.pl line 13 print() on closed filehandle INFO at /usr/local/apache/cgi-bin/newpost.pl line 15 print() on closed filehandle INFO at /usr/local/apache/cgi-bin/newpost.pl line 16 print() on closed filehandle INFO at /usr/local/apache/cgi-bin/newpost.pl line 17 [Sun Mar 21 13:32:10 2004] [error] [client 192.168.2.154] Premature end of script headers: /usr/local/apache/cgi-bin/newpost.pl what''s wrong with my code? Or should i chmod index.html to another user...if so...which user? and what chmod command should i give?

You should check for errors generated by open, cause it definitely looks like the file isn''t opened properly.

open(INFO, ">>$file") or die("failed to open file: $!");

$! is a variable containing an error message.

i know for sure the file exists. when i execute the perl script from command line, index.html gets updated. I tried the "or die("failed to open file: $!") " didnt make a difference

Does your cgi process have the proper permissions to open /usr/local/apache/htdocs/index.html?

this is my error message...

Internal Server ErrorThe server encountered an internal error or misconfiguration and was unable to complete your request.Please contact the server administrator, root@P100Server.mtmc.phub.net.cable.rogers.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.More information about this error may be available in the server error log.Apache/1.3.29 Server at P100Server.mydomain.org Port 80 

how do i set permision?

That is not the error message related to the script, it''s an error message related to the fact that webserver failed to execute the script properly. Check the server log file for the error messasge from the script itself.

And permissions are set by chmod. Check the man pages.

chmod can be used to give global, user or group permissions to write to the file. You can use chown to change the user or group associated with the file.

er....i''m still a bit of a linux newb

i tried chmod +x index.html
i even tried (under /usr/local/apache) chmod 755 htdocs

no change in the error message

Check who''s the owner of the file you''re trying to write to. If it''s not "www" (assuming that''s the user the web server is running as), and that file does not have write permissions, the web server is not allowed to open the file for writing.

As I said, check the web servers error log to see what the error message from the script is. If it says something about permission denied, then I fairly sure this is what''s wrong.

And also, the script must output a content type header before anything else is outputted. That is what "premature end of script headers" is about.

print "content-type: text/html\n\n";
