Adds the passed arguments to the Nmap scan queue.

Only prerule, portrule and hostrule scripts can add new targets.

Parameters

  • ...:
  • targets: A variable number of targets. Target is a string that represents an IP or a Hostname. If this function is called without target arguments then it will return true and the number of pending targets (waiting to be scanned).

Usage:

local status, err = target.add("192.168.1.1")
local status, err = target.add("192.168.1.1","192.168.1.2",...)
local status, err = target.add("scanme.nmap.org","192.168.1.1",...)
local status, err = target.add(table.unpack(array_of_targets))
local status, pending_targets = target.add()

Return values:

  1. True if it has been able to add a minimum one target, or False on failures and if no targets were added. If this function is called without target arguments then it will return true.
  2. Number of added targets on success, or a string error message in case of failures. If this function is called without target arguments then it will return the number of targets that are in the queue (waiting to be scanned).
