I am working on writing two NSE scripts to detect the versions
of DB2 and Oracle.  As I cannot seem to find decent documentation
for either I have been working with packet captures.  While I am
familiar with send hex within normal nmap probe, I am not so sure
when it comes to lua.

Does anyone have any pointers on this?  I am not looking for anything
detailed, just one or two lines sending something as simple as FF FF FF.


I think the hextobin() function in the packet library is what you're looking
for.  From packet.lua:

Parse specifically printed hex string as binary
Only bytes [a-f0-9A-F] from input are interpreted. The rest is ignored.
Number of interpreted bytes _must_ be even. *The input is interpreted in
pairs*.

hextobin("20 20 20")         -> "   "
hextobin("414243")           -> "ABC"
hextobin("\\41\\42\\43")     -> "ABC"
hextobin("   41   42    43  ")-> "ABC"


Thanks much,

Tom
