While it is possible to generalize a DHCPDISCOVER message, I think it would be of limited use since many networks filter DHCP/BOOTP requests unless it is from a certain MAC address (or range). It would be interesting if Nmap/Nping can support a "template" scripting format where additional options can be defined, or where users themselves can define their own protocol using this very template format. (Have a default option set if nothing is specified (e.g. Requesting Client MAC = 00:11:22:33:44:55 if nothing is set, but allow additional options to be parsed and defined for a specific template - maybe something like --payload dhcp type discover sMac 00:AB:CD:EF:AB:CD vendorClass "MSFT 5.0"). In addition, I think reusing Wireshark's dissector filters might also be helpful (e.g. defining all the required options for a payload in a payloads file (e.g. for DHCP), and then allow the user to override the defaults for a certain payload - e.g. bootp.hw.mac_addr=001122334455) On Fri, Sep 30, 2011 at 11:45 AM, David Fifield <david () bamsoftware com>wrote:

If so, how?Can you suggest a good BOOTP probe? It sounds like a good one to add to our nmap-payloads file. http://nmap.org/svn/nmap-payloads David Fifield
