Question

我想使用proxy / socks throw ssh服务器，我在这里找到了很好的例子How do you proxy though a server using ssh (socks…) using php’s CURL?，但是示例不起作用，这是我的代码。

<?php
$connection = ssh2_connect("64.246.126.25", 22);
if(ssh2_auth_password($connection, "ubnt", "ubnt"))
{
    if ($tunnel = ssh2_tunnel($connection, "127.0.0.1", 9999))
    {
        $url = "http://checkip.dyndns.com/";
        $agent= 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.0.3705; .NET CLR 1.1.4322)';
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_HEADER, true);
        curl_setopt($ch, CURLOPT_USERAGENT, $agent);
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_PROXY, "127.0.0.1:9999");
        curl_setopt($ch, CURLOPT_PROXYTYPE, CURLPROXY_SOCKS5);
        $result = curl_exec($ch);   
        echo $result;

    }else{
        echo "Tunnel creation failed.\n";
    }
} 
else
{
    echo "failed!";
}
?>

当我执行此脚本时，我有错误响应：

Warning: ssh2_tunnel() [function.ssh2-tunnel]: Unable to request a channel from remote host in /home/domain.com/ssh2/index.php on line 7
Tunnel creation failed.

我会搜索此错误并尝试修复，但无法解决问题。

任何人都可以帮助我？

似乎ssh_tunnel不能正常工作，ssh_tunnel会请求＆＃34; $ connection＆＃34;执行到指定ip / port的隧道。

在您的代码中，我假设您正在尝试创建一个本地端口，该端口侦听cURL请求作为代理，但基本上您要求ssh服务器连接到自身（127.0.0.1）。

正如您在我的示例中所看到的，通往Google的隧道只是您可以通过其发送流请求的流

$connection = ssh2_connect($sshServerIP, 22);
ssh2_auth_password($connection, $sshServerUser, $sshServerPass);
$sock = ssh2_tunnel($connection, "google.com", 80);
fwrite($sock, "GET /? HTTP/1.0\r\n\r\n");
$body = "";
while (!feof($sock))
$body .= fgets($sock);
echo $body;

您可以在通过以下方式请求隧道到您的IP /端口之前打开本地端口：

$localsock = socket_create_listen(0);
socket_getsockname($localsock, $YourInternetIPaccessible, $openedPort);

然后你的代码会有这些变化：

$connection = ssh2_connect("64.246.126.25", 22);
if(ssh2_auth_password($connection, "ubnt", "ubnt"))
{
    if ($tunnel = ssh2_tunnel($connection, $YourInternetIPaccessible, $openedPort))
    {
        $url = "http://checkip.dyndns.com/";
        $agent= 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.0.3705; .NET CLR 1.1.4322)';
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_HEADER, true);
        curl_setopt($ch, CURLOPT_USERAGENT, $agent);
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_PROXY, "127.0.0.1:$openedPort");
        curl_setopt($ch, CURLOPT_PROXYTYPE, CURLPROXY_SOCKS5);
        $result = curl_exec($ch);   
        echo $result;

    }else{
        echo "Tunnel creation failed.\n";
    }
} 
else
{
    echo "failed!";
}

PHP ssh2_tunnel：使用proxy / socks抛出ssh服务器？
