我想使用代理/袜子抛出ssh服务器,我从这里找到了很好的例子 你如何使用php的CURL使用ssh(袜子...)代理服务器? 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 $result;
}else{
echo "Tunnel creation failed.'n";
}
}
else
{
echo "failed!";
}
?>
当我执行此脚本时,我有错误响应:
Warning: ssh2_tunnel() [function.ssh2-tunnel]: Unable to request a channel from remote host in /home/domain.com/ssh2/index.php on line 7
Tunnel creation failed.
我会用谷歌搜索此错误并尝试修复但无法解决问题。
有人可以帮助我吗?
似乎
ssh_tunnel不是那样工作的,ssh_tunnel会请求"$connection"执行到指定IP/端口的隧道。
在您的代码中,我假设您正在尝试创建一个本地端口,该端口将 cURL 请求作为代理侦听,但基本上您要求 ssh 服务器连接到自身 (127.0.0.1)。
正如您在我的例子中看到的那样,通往 Google 的隧道只是一个流,您可以通过它发送流请求
。$connection = ssh2_connect($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;
在请求通往您的 ip/端口的隧道之前,您可以通过以下方式打开本地端口:
$localsock = socket_create_listen(0);
socket_getsockname($localsock, $YourInternetIPaccessible, $openedPort);
然后进行以下更改的代码:
$connection = ssh2_connect("64.246.126.25", 22);
if(ssh2_auth_password($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!";
}
