Question about logging Option 82

[Andre Schubert]

Hi,

i do it in a similar way. But you may have a problem if the client get a lease from the subnet
10.0.0.0/24 and should then be switch to 192.168.70.16/28.
Another solution could be to patch dhcpd so that either logging statements
gets executed before dhcpd logs DHCPDISCOVER ... no free leases or
that dhcpd logs the needed informations directly within DHCPDISCOVER ... no free leases.

Best Regards,
Andre
