To telnet or to netcat... that's the question

Friday, 31 August 2012

Hi. If I do:

        # telnet 127.0.0.1 5038

        Trying 127.0.0.1...
        Connected to localhost.localdomain (127.0.0.1).
        Escape character is '^]'.
        Asterisk Call Manager/1.0

        Action: Login
        ActionID: 1
        Username: youwanna
        Secret: uwanna

... And asterisk responds:

        == Manager 'youwanna' logged on from 127.0.0.1

But if I use nc and do...

        # nc 127.0.0.1 5038 << EOF
...
 Action: Login
 ActionID: 1
 Username: youwanna
 Secret: uwanna

 EOF         Asterisk Call Manager/1.0

... Asterisk responds:

        == Connect attempt from '127.0.0.1' unable to authenticate

Notice the TEXT is EXACTLY THE SAME (pasted in both cases) tried 762753 times or something
less. Tcp port.
Why is that difference? Is nc sending a different string sequence or what?

TIA...
