[Dibbler] Change lease configuration "on-the-fly"?

[Keshi LI (gmail)]

Hello, all:
I use dibbler-server 0.7.1 Linux to test a DHCPv6 client implementation of
our gateway.

I would like to test the following statements of RFC3315:

18. DHCP Client-Initiated Configuration Exchange

18.1. Client Behavior

18.1.8. Receipt of Reply Messages

   -  Add any new addresses in the IA option to the IA as recorded by
the client.
   -  Update lifetimes for any addresses in the IA option that the
client already has recorded in the IA.
   -  Discard any addresses from the IA, as recorded by the client,
that have a valid lifetime of 0 in the IA Address option.

My question is how can I make dibbler-server change the lease
configuration "on-the-fly" without restarting the dibbler-server?

I have tried the following:

1. My client exchanges Solicit, Advertise, Request and Reply with
dibbler-server and my client enters BOUND state

2. I modify in /etc/dibbler/server.conf the value of valid lifetime or
address in IA_NA option for my client

3. My client enters RENEWing state and sends Request

4. I expect that dibbler-server send Reply with updated IA_NA,
however, dibbler-server sends Reply with Status Code (NoBinding)


Any help would be apprieciated.


Regards

Keshi
