  That's pretty bad.

  I don't mean the error messages.  I mean the formatting.  It's completely unreadable.

  The error message is pretty clear.  The EAP session is *supposed* to finish very quickly.  i.e. less than a second for all packets.  Each packet is supposed to be sent very quickly after the reply to the previous packet.

  That's not happening here.

  Instead, the packet which is producing the error is coming 30 seconds after the previous reply.  There's simply no good reason for that.

  What else is going on?
