PHP中的ssh2_exec無法正常工作

Question

我正在嘗試將php中的exec命令發送到遠程服務器（aerohive）。 但是exec命令什么也沒做。

我已經安裝了ssh2擴展，並且身份驗證也可以正常工作。

這是代碼：

        if (!function_exists("ssh2_connect"))
        die("function ssh2_connect doesn't exist");

    if (!($con = ssh2_connect("myipadresherenotshowingtoyouguys", 22))) {
        echo "fail: unable to establish connection\n";
    } else {
        // try to authenticate with username root, password secretpassword
        if (!ssh2_auth_password($con, "blablabla", "blablabla!")) {
            echo "fail: unable to authenticate\n";
        } else {
            // allright, we're in!
            echo "okay: logged in...\n";

            // execute a command
            $command = 'ssid "Wentzo test2" hide-ssid';
            if (!($stream = ssh2_exec($con, $command))) {
                echo "fail: unable to execute command\n";
            } else {

                $stream2 = ssh2_exec($con, $command_save);
                // collect returning data from command
                stream_set_blocking($stream, true);
                $data = "";
                while ($buf = fread($stream, 4096)) {
                    $data .= $buf;
                }

                fclose($stream);
            }
        }
    }

檢查文件php.ini是否確實禁用了功能disable_functions
