使用 PHP 的 telnet 连接

Question

我需要编写一个 PHP 脚本来远程登录到路由器，运行命令并获取结果。有人知道 PHP 中的 telnet 连接库吗？

更新：这个请求（很明显）是很久以前的。最后，我不得不编写自己需要的客户端库。这个库（以及更多模块）的代码是开源的，可以在github 上找到。 谢谢大家的回答。

Answer 1

Nicholas Hall 的 Github 上有一个可用于 PHP telnet 连接的可爱类： https://github.com/ngharo/Random-PHP-Classes/blob/master/Telnet.class.php

Answer 2

使用 stdin/stream_select 和阻塞流为您提供 20 行 telnet 类似客户端

<?

$socket = fsockopen("192.168.52.1", 8000);

if(!$socket)return;
stream_set_blocking($socket, 0);
stream_set_blocking(STDIN, 0);

do {
  echo "$ ";
  $read   = array( $socket, STDIN); $write  = NULL; $except = NULL;

  if(!is_resource($socket)) return;
  $num_changed_streams = @stream_select($read, $write, $except, null);
  if(feof($socket)) return ;


  if($num_changed_streams  === 0) continue;
  if (false === $num_changed_streams) {
      /* Error handling */
    var_dump($read);
    echo "Continue\n";
    die;
  } elseif ($num_changed_streams > 0) {
    echo "\r";
    $data = fread($socket, 4096);
    if($data !== "") 
      echo "<<< $data";

    $data2 = fread(STDIN, 4096);

    if($data2 !== "") {
      echo ">>> $data2";
      fwrite($socket, trim($data2));
    }
  }

} while(true);

Pear::Net_Socket: http://pear.php.net/package/Net_Socket 为一个简单的 PHP telnet bot 或会话扩展这个类。

Answer 4

<?php

$file = 'somefile.txt';
$remote_file = 'readme.txt';
// set up basic connection
$ftp_server = '127.0.0.1';
$ftp_user_name = 'Till';
$ftp_user_pass = 'Kcp05';
$conn_id = ftp_connect($ftp_server);
// login with username and password
ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
// upload a file
ftp_nb_put($conn_id, $remote_file, $file, FTP_ASCII);
// close the connection
echo "$file sent to $ftp_server as $remote_file\n<br/>";
ftp_close($conn_id);


// finished copying the input.dat to the till now, just need to execute the print command.
// That will copy somefile.txt in the same folder as this .php file to the ftp server root dir.


$header1=chr(0xFF).chr(0xFB).chr(0x1F).chr(0xFF).chr(0xFB).chr(0x20).chr(0xFF).chr(0xFB).chr(0x18).chr(0xFF).chr(0xFB).chr(0x27).chr(0xFF).chr(0xFD).chr(0x01).chr(0xFF).chr(0xFB).chr(0x03).chr(0xFF).chr(0xFD).chr(0x03).chr(0xFF).chr(0xFC).chr(0x23).chr(0xFF).chr(0xFC).chr(0x24).chr(0xFF).chr(0xFA).chr(0x1F).chr(0x00).chr(0x50).chr(0x00).chr(0x18).chr(0xFF).chr(0xF0).chr(0xFF).chr(0xFA).chr(0x20).chr(0x00).chr(0x33).chr(0x38).chr(0x34).chr(0x30).chr(0x30).chr(0x2C).chr(0x33).chr(0x38).chr(0x34).chr(0x30).chr(0x30).chr(0xFF).chr(0xF0).chr(0xFF).chr(0xFA).chr(0x27).chr(0x00).chr(0xFF).chr(0xF0).chr(0xFF).chr(0xFA).chr(0x18).chr(0x00).chr(0x58).chr(0x54).chr(0x45).chr(0x52).chr(0x4D).chr(0xFF).chr(0xF0);

$fp=pfsockopen("127.0.0.1",23);

echo "Telnet session opening ...";

sleep(4);

fputs($fp,$header1); 
sleep(4); 

fputs($fp,"Till\r");
sleep(2); 
fputs($fp,"Kcp05\r"); 

sleep(2);
fputs($fp,"notepad\r"); 

sleep(3);

echo "Telnet session closing ...";

fclose($fp);

?> 

这对我有用。第一部分将ftp文件上传到服务器，第二部分将lo到telnet服务器，并执行一个可以使用您刚刚通过ftp上传的文件的程序。刚刚测试过了。
