Recently went closed source, but is still essentially free. A very versatile tool, once you fully understand the results.Īlso,You can learn how to perform a simple Nmap scan by reading this article. Nmap is free and open source.Can be used by beginners (-sT) or by pros alike (packet_trace). It may be used to discover computers and services on a computer network, thus creating a 'map' of the network.Nmap runs on most types of computers and both console and graphical versions are available. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use,and dozens of other characteristics. It was designed to rapidly scan large networks, although it works fine against single hosts.Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. Nmap (Network Mapper) is a free open source utility for network exploration or security auditing. I think everyone has heard of this one, it recently had a version 5 release. Its been a while since I have posted about some hacking tools and with increasing number of emails asking me to do an article on it,I finally decided to cover it up.Hacking tools are developed by some really good coders out there to ease out many complex tasks which have to be done manually and took painstakingly great deal of time and effort.All these tools provided here are free of cost,are tried hands on and are being actively developed by community,and if not,their alternatives are provided.To summarize it up,these are the 7 must have tools for every hacker out there.
