Hi, all. I use FC5 linux to develop CGI program. The config file of Apache are defaule and I put my script on /var/www/cgi-bin/ folder. I do not modify any config file in FC5 and shutdown the firewall. But I find I can not use the IO::socket module in the apache web environment. The script is below: 
#!/usr/bin/perl
use strict;
use warnings;

use IO::Socket;

my $pop3 = IO::Socket::INET->new(
            PeerAddr => "pop3.163.com",
            PeerPort => 110,
            Proto    => 'tcp',
            Timeout  => 20 );
print "Content-type: text/html\n\n";
print "Result: ";
print $pop3;

The permission of the script file is 755, and the path of the file is /var/www/cgi-bin/test_socket.pl

When I run the script in command line. It print the result:

Content-type: text/html

Result: IO::Socket::INET=GLOB(0x9314838)

But I run it in apache by the URL: http://192.168.0.200/cgi-bin/test_socket.pl . It only print:

Content-type: text/html

Result:

It seem that the value of the $pop3 is undef. So the use of IO::Socket is failed on apache.

Why have this problem. How can I get the rignt result?
