Documentation - Free Security Scanner For Network Exploration & Security Audits.
The Nmap project tries to defy the stereotype of some open source software being poorly documented by providing a comprehensive set of documentation for installing and using Nmap. This page links to official Insecure.Org documentation, and generous contributions from other parties. The primary documentation for using Nmap is the Nmap Reference Guide. This is also the basis for the Nmap man page (nroff version of nmap.1). It was rewritten from scratch in late 2005 and is meant to serve as a quick-reference to virtually all Nmap command-line arguments, but you can learn even more about Nmap by reading it straight through. We have been overwhelmed by offers to translate the man page to other languages. The links above go to the HTML guide. Installation is made easy by the detailed Nmap Installation Guide. One of Nmap's most exciting new features is the Nmap Scripting Engine, which extends Nmap's functionality using the simple and efficient Lua programming language. Uh-oh!

Dhcp Explorer - Discover DHCP servers on your LAN
Dynamic Host Configuration Protocol (DHCP) is a client-server networking protocol and uses the same two IANA assigned ports for BOOTP: 67/udp for the server side, and 68/udp for the client side. A DHCP server provides configuration parameters specific to the DHCP client host requesting, generally, information required by the client host to participate on an IP network. DHCP also provides a mechanism for allocation of IP addresses to client hosts. DHCP server is a useful tool that automates the assignment of IP addresses to hundreds of workstations in your network. The server maintains a pool of IP addresses that you use to create scopes.
Seguridad Informática
Background Hispasec was founded at the end of 1988 with the launching of "una-al-día" ("One-Per-Day") which is considered to be the first daily service of technical information about IT security in Spanish language. It was created by a group of specialists with the aim of divulgation of the necessity of IT security for users of new information technologies. The success obtained by "One-Per-Day" and the rest of public actions implemented by Hispasec (i.e. analysis, comparatives, new developments, etc.) originated in a practically spontaneous way a demand of service by professionals and companies. Our lab, Hispasec Sistemas, was created in year 2000 in order to attend this demand. Keeping track of the original path, the new direction adopted by Hispasec Sistemas makes possible to maintain and reinforce the public and free services given to the community but also to attend the increasing demand of professionals and companies. Philosophy Security, our reason for being
Nslookup
Es un programa, utilizado para saber si el DNS está resolviendo correctamente los nombres y las IP. Se utiliza con el comando nslookup, que funciona tanto en Windows como en UNIX para obtener la dirección IP conociendo el nombre, y viceversa... Por ejemplo: Al preguntar quién es «es.wikipedia.org» se obtiene: nslookup es.wikipedia.org Server: 192.168.1.1 Address: 192.168.1.1 Non-authoritative answer: Name: es.wikipedia.org Address: 66.230.200.100 Al preguntarle quién es "66.230.200.100" se obtiene: > 66.230.200.100 Server: 10.1.232.18 Address: 10.1.232.18:53 Non-authoritative answer: 100.200.230.66.in-addr.arpa canonical name = 100.200.230.66.rev.wikimedia.org. 100.200.230.66.rev.wikimedia.org name = rr.pmtpa.wikimedia.org.
