how to telnet to a switch that without a username prompt?

[sayabaobao]

Hello all,
I am using perl net::telnet to login remote switches by
$t->open($device);
$t->login($username, $password);
and everything goes on very well.

The problem is that now I have to telnet another switch that doesn't have a username prompt...which means only $password is needed when login...
but so far as i know that both username and pw are parameters of Telnet.pm login()....How can I login such kind of switch?

Thanks a lot!

You can avoid using login(). Try using waitfor() method to wait for the prompt and print the password:

$t->open($device);
$t->waitfor('/password: $/i');
$t->print($password);
##
$t->print('y');
