Perl代码获取ip地址

Question

我想获取访问者的ip地址记录。我可以用PHP做到这一点，但是当我尝试这个Perl代码（Perl中的新手）时，当访问者访问我的网站时，它只记录我网站的主机IP地址（在这种情况下为三脚架），如下所示：19Apr11 20:25 ：35 10.126.24.9。但那不是我想要的;我想要访客的IP地址？我在这里做错了什么？感谢

#!/usr/bin/perl 
# For logging IP address of visitors. 
# This is stored into the cgi-bin folder and called from the index.htm file 
# using <img src="cgi-bin/script.pl"> 
# Specify location and name of log file to be maintained. 
my $LogFileLocation = "iplog.txt"; 
# Directory must exist and have correct permissions. 
use strict; 
my ($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) = localtime; 
my @mon = qw(Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec); 
$year += 1900; 
$year = substr($year,-2); 
$mday = $mday < 10 ? "0$mday" : $mday; 
$hour = $hour < 10 ? "0$hour" : $hour; 
$min = $min < 10 ? "0$min" : $min; 
$sec = $sec < 10 ? "0$sec" : $sec; 
my $address = $ENV{X_FORWARDED_FOR} || $ENV{REMOTE_ADDR} ||""; 
open W,">>$LogFileLocation"; 
print W "$mday$mon[$mon]$year $hour:$min:$sec\t$address\n"; 
close W; 
# end of script

use CGI; ## load the cgi module 

print "Content-type: text/plain; charset=iso-8859-1\n\n"; 
my $q = new CGI; ## create a CGI object 
print $q->remote_host(); ## print the user ip address
