karpg

KARPG is a cli ARP packet generator.
KARPG uses self designed command line parser , usgin strong regex and some string processing functions.

This project is under development.

commands

There are some functions you can issue in this program to create & maintain your arp message :

create an ARP message :

    YOUR_ARP_MESSAGE_NAME = ( arp_fields* )

       arp_fields is : (  opcode = value | hlen = value | plen= vlaue | 
                          htype = value | ptype = value | sip = vlaue | tip = vlaue |
                          smac = vlaue | tmac = value )

if you do not specify any arp_fields in paranthesis , some default values are given to above fields in ARP message : opcode = 1 hlen = 6 plen= 4 htype = 1 (Ethernet) ptype = 0x0800 (IPv4) sip = 0.0.0.0 tip = 255.255.255.255 smac = 00:00:00:00:00:00 tmac = ff:ff:ff:ff:ff:ff

but these values can be changed easily by issueing create function again on that message name :

ex: 
  create a message with name (mess1) and with default fields
        >>  mess1=()
        
  change some values: 
        >>   mess1=(sip=192.168.10.1 , htype=2 , opcode=2)

or you can simply create a message with your initial fields:

    ex
        create a new message with name (mess2) and with default fields   
             >> mess2=(opcode= 2 , sip =192.168.10.1 , tmac= 01005e010000)

checking message contents :

  Another useful command is ( show MESSAGE_NAME ) which prints out fields of that message
  
  ex 
     >> show mess2
     OUTPUT: 
      (opcode: 2 , heln: 6 , plen: 4, htype: 1,
      ptype: 2048, smac: 000000000000, tmac: 01:00:53:01:00:00, sip: 192.168.10.1 , tip:255.255.255.255)

see which interface was set:

 you can check the current selected interface in program by ( show int or show interface ).

 by default no interface is selected
 
 ex 
    >> show int
    OUTPUT:
      Interface = Not set
      
      
    >> show int
    OUTPUT:
      Interface = vmnet1

send an ARP message

   This function is for sending . This version of KARPG does not support parser for send , 
   so it simply asks you interactively for some informations.
   
   defaults:
    smac: mac address of selected NIC
    tmac: ff:ff:ff:ff:ff:ff
    count: 1
   
   ex
      >> send
          message: mess1
          smac :[d for default] d
          tmac :[d for default] d
          count :[d for default] 12

setting interface :

 Another useful command is (setint) , which sets an interface for you.
     ex:
          >> setint vmnet1
          OUTPUT:
            interface {vmnet1} was set as default interface
