 Resolv v0.9.9a          /      \	
=========================.______.================================

This Software has been tested in the following plataforms:

 + OpenBSD 2.9 
 + FreeBSD 4.1 
 + Debian GNU/Linux 2.2

If beams to work well this program in other systems I thank in
advance to you. 


  Information
=:-----------:= 

Resolv allows to solve the names of a direction or a rank of directions IP,
allowing to maintain a " map " of the names that it has assigned each
host that comprises of a certain network. 

The System's Administrator commonly assigns host a name that has
relation with the operating system that it has installed or by the task
that carries out in a certain network; for example: 

 red -> 202.72.112.0-25

	202.72.112.0 -> mail.red-ejemplo.com
	202.72.112.1 -> cisco.red-ejemplo.com
	202.72.112.2 -> www.red-ejemplo.com
	202.72.112.3 -> user10.adsl.red-ejemplo.com
	...
	...
In this example it is possible to be identified that one of hosts is to
router Cisco and another one is used for mail server, etc. 

And it is possible that with this information, the attacker will do
massive  attacks to one or several networks.

'Resolv' tries to serve as a network analisis tool, available  for the 
system's administrators or users  who wish to prove and
to identify ways of obtaining of information in one or several networks.


  Features
=:---------------:=

 + With Resolv we can send the results to a file. 
 + Do Search of patterns in the host names.
 + Posibilidad de indicar un rango de direcciones IP como un solo argumento.
 + Logs the result to a text file.
 + Searching of patterns in the host names.
 + Obtaining of list of IP address from a text file.
 + To Search of multiple patterns in a text file.
 + Launching the process number of Resolv in background.
 + Statistical Report of the scanning.
 + Run programs when pattern would be found.


   Examples
=:---------:=

 + To resolve the name of the following ip adrress:
	
	# resolver 192.168.1.2

 + To Scan  one or several networks.

	# resolver 192.168-170.0-10.0-255

 + To Scan  one or several networks by using ranks of ip address and
   get the canonical name if the host had one.

	# resolver -a 192.168-170.0-10.0-255

 + To search one spefic patten in the list of hostname of one or 
   more networks:
   < por defecto todas las concordancias se logean en el fichero pattern>
	
	# resolver -s cisco 192.168-170.0-10.0-255

 + To search multiple patterns in the hostnames in one or more 
   networks:
   <por defecto todas las concordancias se logean en el fichero pattern>

	# echo "ftp" >> lista_patrones
	# echo "www" >> lista_patrones
	# echo "mail" >> list_patrones

	# resolver -x lista_patrones 192.168-170.0-10.0-255
	
 + To extract one or more ip adrress from one text file:
	
	# resolver -l lista_direcciones_ip
 
 + To log the result to text file

	# resolver -f salida -a 192.168-170.0-10.0-255

 + Run nmap when "ftp" pattern would be found

	# resolv -s ftp -e "nmap%s-P0%s-p%s21%s%i" 192.168.1.0-255
