In which scenario is this needed? And can it be dynamic or static in respect of security issues the manual mentions? In this case I have to build tunnels or something to all clients to get them one and the same network IP. Arrange that all clients come at the gateway with a local IP all in one /24 network so netmap translation becomes straitghtforward. netmap several networks to same size networks? (like local/26 get public/26 and that several times until I run out of addresses? Yet again, all addresses also to be set as IP on the public interface? scr-nat each local IP to public IP? Do I need to set this public IP in public interface of my router? (ip/address) I red all the manuals and some post but still have some items in need of clarifications: What is now the best scenario and where to look at. Now I have obtained a /24 address range (254 addresses) that I can use to give clients fixed public IP's. Up to now all these addresses where scr-natt'd to one IP assigned to me by ISP. Presently I have clients coming in at my LAN port with about 14 different networks. Want to start making money as a white hat hacker?

In future posts, I will explore more of its capabilities and show you how to write your own Nmap scripts. The Nmap scripting engine is a powerful item in our arsenal of hacking tools that can be tailored to a multitude of tasks. Ruby on Rails is very popular open-source web design framework that is behind millions of database driven web apps, so this vulnerability is likely to still be out there in thousands of websites. Note that this script is designed to find the CVE2013-0156 vulnerability, which is a vulnerability in Ruby on Rails. nse (nmap scripting engine), so we can find the scripts by using the Linux locate command with the wildcard *.nse. Step 2: Find the Nmap Scriptsįrom the terminal, let's look for the Nmap scripts. You can't really have a security/hacking platform without Nmap. If you aren't using Kali, but instead one of the many hacking/security distributions such Buqtraq's Black Window, Security Onion, BackTrack, or another, no problem-Nmap is built into ALL of them. Step 1: Fire Up Kali & Open a TerminalĪs usual, let's start by firing up Kali and opening a terminal. In this tutorial, we will look at the scripts that have been shared and are built into Kali (we will write scripts in a future tutorial), and will examine how to use them to do thorough recon on our target, to increase the possibility of success, and reduce the possibilities of frustration. More sophisticated and accurate OS version detection.It allows users to write their own scripts and share these scripts with other users for the purposes of networking, reconnaissance, etc. The Nmap scripting engine is one of Nmap's most powerful and, at the same time, most flexible features. I have done a couple of tutorials on using Nmap, but one thing I have not covered is the scripting engine built into it. Although I discourage the use of Windows for hacking, Nmap does have a version for Windows with a nice GUI called Zenmap. Although it is not perfect, it is excellent for active reconnaissance. Nmap is one of the few tools that every hacker should be conversant in. If you aren't willing to do that, you will never be successful in this field of endeavor. Long before we ever begin the hack, we have spent hours, days, and maybe months doing reconnaissance. There is NO SILVER BULLET that succeeds under all circumstances. I know I have said it before, but bear with me as I say it again for the newcomers. Experienced and expert hackers know that 70-80 percent of a good and successful hack is dependent upon successful and accurate reconnaissance. Novice hackers often jump into a hack/exploit without doing proper recon and either fail or get caught. Those of you who have been reading my posts here for awhile know how much I emphasize good reconnaissance.
