During the ping probe effectiveness research, we found that UDP probes
that have a payload work better than those without, and probes with a
payload specific to the protocol work better still. As well as being
more effective for host discovery, meaningful payloads sometimes allow a
port to be classified as open rather than open|filtered.

I have in a branch code that sends protocol payloads for ports 53, 123,
137, 161, and 1434.
      svn co --username guest --password "" svn://svn.insecure.org/nmap-exp/david/nmap-payloads
The payloads are taken from nmap-service-probes. They are:

53: DNSStatusRequest "\0\0\x10\0\0\0\0\0\0\0\0\0"
123: NTPRequest 
137: NBTStat "\x80\xf0\0\x10\0\x01\0\0\0\0\0\0\x20\x43\x4bAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA\0\0\x21\0\x01"
161: SNMPv3GetRequest 
1434: Sqlping "\x02"

This could also be useful for Nping in UDP mode. I'll add it to the TODO
list. I could add a flag, something like --proto-payload, that adds
those payloads based on target port numbers. What do you think?
