Re: [NSE] nmap timing info for scripts

["Eddie Bell" <ejlbell () gmail com>]

Just hacked this up. Maybe we could add it to stdnes.lua along with
Thomas's patch. At least this way script could be uniform in their
timing policies with an option to deviate if needed.

 -- Get standard timeout duration based on nmap's current timing level
 -- Duration ranges from 20 seconds for T0 to 1 second for T5
 function get_timeout()
         t = { 20000, 15000, 10000, 5000, 3000, 1000 }
         return t[nmap.timing()+1]
 end

Called like this

sock:set_timeout(stdnse.get_timeout())
