ניסתי משהו כזה:

PHP קוד:

<?php
if (isset($_POST["send"]))
{
$sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
socket_set_nonblock($sock);
socket_connect($sock,$_POST['server'], 22);
socket_set_block($sock);
switch(socket_select($r = array($sock), $w = array($sock), $f = array($sock), 5))
{
        case 2:
                echo "[-] Connection Refused\n";
                break;
        case 1:
                echo "[+] Connected\n";
                break;
        case 0:
                echo "[-] Timeout\n";
                break;
}
}
?>
<FORM action="<?php echo $_SERVER["PHP_SELF"]; ?>" method="POST">
<TR>
<TD><INPUT type="TEXT" name="server" size=15 maxlength=50 value="<?php echo $_POST["server"]; ?>"></TD>
<TD align="right"><INPUT type="SUBMIT" name="send" value="בדוק"></TD>
</TR>

תראו בעצמכם מה זה מחזיר לי:
