Thanks for the use of hook pointer. I'm able to retrieve the data 
elements directly from the hook, but I am still struggling for feeding 
this data into a table. All the searching I find only speaks of feeding 
data in from a file. I can't find any source for how to feed this "live" 
data into a table.


hook Notice::policy(n: Notice::Info)


if ( n$sub == "remote" && n$note == Scan::Port_Scan || n$note == 
Scan::Address_Scan && n$sub == "remote")


local ssrc= n$src;

local sts= n$ts;

local snote = n$note;

print ssrc, sts, snote;
