Set variable from dropdown menu

[Nucleus]

I am using the below to sent ssh commands through a web interface. For example, to get the hostname of a Linux computer:

 

index.html

<form action="phpseclib/hostname.php" method="get" target="_blank">

    <select name="clients">

        <option value="SelectClient">Select Client</option>

        <option value="192.168.0.51">Client001</option>

        <option value="192.168.0.52">Client002</option>

        <option value="192.168.0.53">Client003</option>

    </select>

    <input type='submit' />

</form>

 

hostname.php

<?php

include('Net/SSH2.php');

include('variables.php');



$ip = $_GET['clients'];

$ssh = new Net_SSH2('$ip');

if (!$ssh->login($user, $pass)) {exit('Login Failed');}

echo $ssh->exec('hostname');

?>

 

In hostname.php if I set the $ip variable manually, everything works as expected. But when I use

$ip = $_GET['clients'];

I get a message saying "Login Failed"

 

When I echo $ip I correctly get the IP Address of the dropdown selection.

 

What I'm I doing wrong here?

 

Thanks

This fixed it

 

<?php

include('Net/SSH2.php');

include('variables.php');

 

$ip = $_GET['clients'];

$ssh = new Net_SSH2($ip);

if (!$ssh->login($user, $pass)) {exit('Login Failed');}

echo $ssh->exec('hostname');

?>
