[RADIATOR] Radiator with Windows Server 2008 DHCP

Hi Alan,

Just run a test using Wireshark on the DHCP end and all I get is the
confirmation of 4 DHCP DISCOVER packets being received by the DHCP
server and then no response. Presumably this means that Radiator is
attempting to make a connection 4 times with each one failing for some
reason?

Cheers,

Richard

Hi Alan,

I don't quite follow what you mean regarding the PoolHint?

Also, I can confirm that the DISCOVER packets are being received at the
DHCP server as they appear in the Windows Firewall logs. Will get
Wireshark out and test where they go from there in a bit.

Cheers,

Richard

Hi,

>       <AuthBy DYNADDRESS>
>       AddressAllocator dhcpallocator
>       PoolHint 255.255.255.240
>       </AuthBy>

from the manual:

Note: the PoolHint supplied in the AuthBy DYNADDRESS clause must be a
subnet
definition that is understood by the DHCP server for the purposes of
address allocation


goodies/addressallocatordhcp.cfg  has a nice example config to look
at....  I find
if you are having issues and make no progress just looking at the
RADIATOR
debug logs, then look at the other end - see what your DHCP server is
bleating
about and check with eg wireshark, tcpdump or snoop, that traffic is
going
between the hosts involved!
