Network Scanning

Network ping sweeping

required net-ping gem

  1. gem install net-ping
  1. #!/usr/bin/env ruby
  2. # KING SABRI | @KINGSABRI
  3. #
  4. require 'net/ping'
  6. @icmp = Net::Ping::ICMP.new(ARGV[0])
  7. rtary = []
  8. pingfails = 0
  9. repeat = 5
  10. puts 'starting to ping'
  11. (1..repeat).each do
  12.   if @icmp.ping
  13.     rtary << @icmp.duration
  14.     puts "host replied in #{@icmp.duration}"
  15.   else
  16.     pingfails += 1
  17.     puts "timeout"
  18.   end
  19. end
  21. avg = rtary.inject(0) {|sum, i| sum + i}/(repeat - pingfails)
  22. puts "Average round-trip is #{avg}\n"
  23. puts "#{pingfails} packets were dropped"

Port Scanner

If you got what we’ve represented in Ruby Socket section, then here we wrapping up and do some application depends on it.
scanner.rb

  1. #!/usr/bin/env ruby
  2. #
  3. # KING SABRI | @KINGSABRI
  4. #
  5. require 'socket'
  6. require 'thread'
  7. require 'timeout'
  9. host = ARGV[0]
  11. def scan(host)
  12.   (0..1024).each do |port|
  13.     Thread.new {
  14.       begin
  15.         timeout(3) do                    # timeout of running operation
  16.           s = TCPSocket.new(host, port)            # Create new socket
  17.           puts "[+] #{host} | Port #{port} open"
  18.           s.close
  19.         end
  20.       rescue Errno::ECONNREFUSED
  21.         # puts "[!] #{host} | Port #{port} closed"
  22.         next
  23.       rescue Timeout::Error
  24.         puts "[!] #{host} | Port #{port} timeout/filtered"
  25.         next
  26.       end
  27.     }.join
  28.   end
  29. end
  31. scan host
