The telnet login fails if the user has no password

[lovecreatesbea...@gmail.com]

The telnet login fails if the user has no password. I mean the user is
not prompted with the ``Password:'' string and log in, as shown in
below case 2.

$cnn->login($user, $pass);

It works in case 1. How can I make a script work with both cases?

Thank you.

CASE 1:

$ telnet 192.168.4.30
Trying 192.168.4.30...
Connected to 192.168.4.30.
Escape character is '^]'.

login: guest
Password:
[guest@BS2000e-1 ~]$ exit
logout
Connection closed by foreign host.
$

CASE 2:

$ telnet 192.168.5.10
Trying 192.168.5.10...
Connected to 192.168.5.10.
Escape character is '^]'.

login: guest
[guest@BS3000e-0 test]$ exit

logout
Connection closed by foreign host.

I sincerely hope you have good firewalls, if you are allowing telnet
logins without a password.

As it says in the docs, if ->login doesn't do what you want, use ->print
and ->waitfor instead.

Thanks, I just read it. Does ->print display password on terminal and
anybody sees it? Does the ->login work this way also?

Why ask? Both of those are questions you can answer yourself by
trying the methods.
