NSE(lua)

Usage

Same lines.
--script <NSE FILE>
--script=<NSE FILE>

Using NSE

$ nmap 192.168.0.1 --script <NSE FILE>

$ nmap 192.168.0.1 --script=<NSE FILE>

Use NSE with nse arguments

$ nmap 192.168.0.1 --script nse --script-args <ARGUMENTS>

Use NSE with nse arguments file

$ nmap 192.168.0.1 —-script nse --script-args-file <FILE>

Use NSE Arguments Script

$ nmap -sC --script-args 'user=foo,pass=",{}=bar",paths={/admin,/cgi-bin},xmpp-info.server_name=localhost’

nmap.registry.args = {
  user = "foo",
  pass = ",{}=bar",
  paths = {
    "/admin",
    "/cgi-bin"
  },
  xmpp-info.server_name="localhost"
}
