\000 in "octets" attribute?

Hi,

Hm, what exactly do you mean?

This is the behaviour I described as fine (the \000 is kicked since it is the 
last character, and what remains is a completely empty attribute), and what 
your colleague would probably describe as bad: he thinks, the \000 should be 
sent in the packet.

Actually, I don't think that Calling-Station-Id is on the wire at all, since 
empty attributes are supposed to be suppressed. And that's why the packet 
arrives on the server without this attribute:

>         User-Password = "b"
>         NAS-Port-Type = xDSL
>         MS-CHAP-Challenge = 0x00
>         NAS-IP-Address = 127.0.0.1
>         Stripped-User-Name = "ppp1"
>         Realm = "example.com"

Since you _want_ the \000 to be sent, I don't see why it "seems to work here"? 
Maybe the only thing that would really give clarity about what is really 
happening is a pcap capture with ethereal or similar.

Greetings,

Stefan
