ssh2 extension

[ochi]

hello, I really can't understand ssh2 extension... It just works "sometimes":

 

$con = ssh2_connect("xx.xx.xx.xx", 22) or die ("Error, address + port");
$autent = ssh2_auth_password($con, 'user', 'password') or die ("Error, user + password");
$stream = ssh2_exec($con, 'ps -ax') or die("executing");
stream_set_blocking($stream, true);     
$output = stream_get_contents($stream,-1);
echo $output; 
fclose($stream); 

 

But $output is empty.

 

The most weird is that if I write:

 

$stream = ssh2_exec($con, 'mplayer rtsp://localhost/sample.mp4') or die("executing");

 

It works!

 

Thank you for your help!
