Subject: Threading methods & args

Well, this is my simple port scanner
Instead of actually Threading the scan it just prints:
"C:\Users\admin>C:\Ruby193\bin\ruby.exe
C:\Users\admin\Desktop\port-scanner.rb
choose host:"
 why ?



require 'socket'

def scanner
  print "choose host: "
  arg1 = gets.chomp
  print "choose starting port: "
  arg2 = gets.to_i
  print "choose ending port: "
  arg3 = gets.to_i
  while arg2 <= arg3
    begin
      s = TCPSocket.new(arg1, arg2) # arg1 = host, arg2 = sport, arg3 =
eport
      if s
        puts "Port #{arg2} is open!"
      end
    rescue
      puts "Port #{arg2} is closed!"
    end
    arg2 += 1

  end
end

Thread.start {scanner}
