Hallo to all,
I have write a little script for connecting to cisco router BUT I have a
problem: I have to send to router all the commands and then I have to read
the output.
If I send a command1 and read the output for command1 the script works
well,
If I sent command1 , I send command2 and then I read output for command1
and command2 it works well.
If i send command1 and then I read the output for command1 then send
command2 I can't read the output for the command 2.
Why?
How can I do?
Thank you in advance,
Mario.

P.S. following the script and the password



================================ SCRIPT ================================
<?
include "router.php";

$r=new Router();

$r->connect('router_address', $errno, $errstr);

$r->login($myLogin,$myPassword);


$o=$r->runCommand('sho ver'); //<==== works
echo '<pre>';
var_dump($o);
echo '</pre>';

$o=$r->runCommand('sho int descr'); //<==== don't works

$r->disconnect();

?>



==================================== Class ==========================================
