hello perlmonks, everybody!

I am currently working on a intranet website in our company and still learning on web and perl programming.

I have a website on a unix apache2 server with perl installed and there's an FTP option in my webpage to get archive files from an ftp server.

I use perl cgi NET::FTP module, with username,password provided at script and filename from the html form.

To check if my cgi perl ftp script runs at unix, i hardcoded the username/password/target file at ftp server and run it and works fine (can get the target file).

But when i try to run my cgi perl ftp script (with username/password/target file hardcoded) thru my website, i get error 500 Internal Server Error then i check the error logs and shows me below.

"...Cannot open Local file "target_file": Permission denied, referer: 
+http://www.???.com/get_FILE.html
"...malformed header from script. Bad header=retrieving file from serv
+er: get.cgi, referer: http://www.???.com/get_FILE.html

My cgi perl ftp script with username/password/target file hardcoded:

#!/usr/bin/perl -wT

use Net::FTP;
print "retrieving file from server\n";
$ftpobj = Net::FTP -> new ("100.eee.yyy.xxx");
$ftpobj -> login("user","pass");
$ftpobj -> cwd ("target_directory");
$ftpobj -> get ("target_file");
$ftpobj -> quit;
print "file size ",-s "target_file"," bytes\n";

Can you help me out guys? I've put the permissions to 777 of the script and the directory but still same error "permission denied... :(

Thanks!
