Public bug reported:

Binary package hint: chillispot

The way chillispot prepares a hash for the "Message-Authentifactor" is not 64 bits proof.
As a result the 32 bytes string hash is only filled with 8 bytes (as

wrong field reported sniffing the wire with wireshark :
Message-Authenticator: DF09B19E000000000000000000000000

good one, obtained with radtest and radclient :
Message-Authenticator: 9A67B23A03BDC920A49E0F59413023B8

As you can see the string is truncated.  Then the radius server reject
the authentifaction request asap with that error :

Wed Sep  9 12:48:00 2009 : Error: Received packet from 127.0.0.1 with
invalid Message-Authenticator!  (Shared secret is incorrect.) Dropping
packet without response.

tried with Ubuntu 8.04 server AMD64, Ubuntu 9.04 server AMD64.

all is working fine on Ubuntu server 9.04 i386, on a 32 bits system.
