How to do a public socket proxy to access google?

What is our goal?

1. Access google

2. Access google

What should we prepare for it ?

1. A vps in Sigapore (Ubuntu)

2. A Linux server inside (CentOS)

In Linux Server:

ssh-keygen -t rsa

cat ~/.ssh/id_rsa.pub -> copy the content to VPS's ~/.ssh/authoirzed_keys

check.php

#!/usr/bin/php

<?php

// 程序使用csp.pl 通过socket proxy 192.168.50.247 9999 检测www.youtube.com是否可以打开

$lineNum=system('perl csp.pl | wc -l');

if ($lineNum==1) {

    system('echo `date` 停止运行 >> result');

    system("ps aux | grep ssh | grep 9999 | awk '{print $2}' | xargs -i kill -9");

    system("nohup ssh -ND 0.0.0.0:9999 root@sigapore.myciscolab.net&");

}

elseif ($lineNum>1000) {

    system('echo `date` 正在运行 >> result');

}

else {

    system('echo `date` 状态异常 >> result');

}

?>

csp.pl

#!/usr/bin/perl

use strict;

use LWP::UserAgent;

my $ua = LWP::UserAgent->new(

   agent => q{Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; YPC 3.2.0; .NET 

   CLR 1.1.4322)},

   );

   $ua->proxy([qw/ http https /] => 'socks://192.168.50.247:9999'); # Tor proxy

   $ua->cookie_jar({});

   my $rsp = $ua->get('http://www.youtube.com/');

   print $rsp->content;
