使用phpseclib和net_ssh如何使用$ssh-> exec su到root

所以我需要执行一个命令但它只会运行,如果我su到root(或sudo)但我似乎无法弄清楚如何将命令发送到su到root

(我可以使用loginuser登录并执行其他命令)

http://phpseclib.sourceforge.net/ssh/examples.html

我的代码如下

<?php
include('Net/SSH2.php');

$ssh = new Net_SSH2('255.255.255.255',22);
if (!$ssh->login('loginuser', 'fakepassword')) {
    exit('Login Failed');
}

echo $ssh->read('[prompt]');
echo $ssh->write("su\n");
echo $ssh->read('Password:');
echo $ssh->write("rootfakepassword");
echo $ssh->read('[prompt]');
echo $ssh->exec('cc get_wireless_status');
?>

我也尝试使用exec命令做大致相同的事情而没有运气

有什么建议？

当前版本的代码(不起作用)

<?php
    include('Net/SSH2.php');

    $ssh = new Net_SSH2('255.255.99.74',22);
    if (!$ssh->login('loginuser', 'password')) {
        exit('Login Failed');
    }

    echo $ssh->read('loginuser@intranet:/home/login >');
    $ssh->write("su\n");
    echo $ssh->read('Password:');
    $ssh->write("rootpassword\n");
    echo $ssh->read('intranet:/home/login #');
    $ssh->write("cc get_wireless_status\n");
    echo $ssh->read('[prompt]');
?>

腻子文本的登录

login as: loginuser
loginuser@255.255.99.74's password:

这应该工作：

<?php
    include('Net/SSH2.php');

    $ssh = new Net_SSH2('www.domain.tld');
    if (!$ssh->login('username', 'password')) {
        exit('Login Failed');
    }

    echo $ssh->read('username@username:~$');
    $ssh->write("su\n");
    echo $ssh->read('Password:');
    $ssh->write("password\n");
    echo $ssh->read('username@username:~#');
    $ssh->write("cc get_wireless_status\n");
    echo $ssh->read('[prompt]');
?>
