Few words on Wireless network topology. Each Wireless network has two major components, either stations (STA) or access points (AP). Wireless network operates in one of two modes: ad-hoc (peer-to-peer) or infrastructure mode. In the ad-hoc mode each client (STA) communicates directly with other clients within the network. In the infrastructure mode each client (STA) sends its communication requests to a central station, which is the Access Point (AP). The access point acts as an Ethernet bridge. A client and an access point must establish a relationship prior to exchanging data. Once established the client-access point relationship could be in any of the following three states: Be first to comment this article | Add as favourites (53) | Read more... |

If you have heard a little bit about computer history or have read old-time hackers talk about their favorite machines, such as in the Jargon File [http://www.tuxedo.org/~esr/jargon/], then you probably have this vague idea of the pool of primordial soup embodied in the operating systems of the past. PDP-10, MULTICS, VAX, VMS, TOPS-20, CP/M, blah blah blah....what is all this? In order to really know ones stuff computerwise, many sources, mostly reflecting an older viewpoint, say that you should know about all of this stuff. Today, one can navigate the Internet in all of its depth without knowing a thing about VMS, the topic at hand. For a few reasons, however, I still think its worth having at least some familiarity with for the well-rounded hacker.

Local hacking is, what I myself call, the way of gaining access to a computer while actually sitting at it. This article is a short listing of my experience in this area. When will we need the advantage of Local access Let me take some examples. At the school i am currently attending, each student have a laptop. This laptop is borrowed from the school but the student may take it home with him or her every day of the year. I suppose i don't even have to mention that with a bit more than 200 laptops in circulation there is quite some problems from time to time.That is why the school has a technician who repairs computers and, from time to time, Ghost's them (Norton Ghost).

One of the first phases of a network penetration test or vulnerability assessment is typically to perform a network port scan to identify all the active services. There are a large number of port scanning tools and techniques available to do this and it is not the purpose of this article to discuss them. This article focuses on some of the tools and techniques that can be used to determine whether there is an Oracle TNS listener active on any of the identified listening ports. [The Oracle Transparent Network Substrate (TNS) protocol defines the communication protocol used between the database server and the database client applications. The TNS protocol provides an application interface to all industry-standard networking protocols e.g. TCP/IP. An example of a TNS enabled application is SQL*Net.]

This article (supposedly) serves to instruct the reader into the methods and workarounds when dealing with DNS takeovers and spoofing. Unfortunatley, there seems to be some confusion within circles as to the difference between DNS takeovers and spoofing. This document trys to answer these questions. Also, please note that I am not trying to instruct anybody in the In's and Out's of the DNS system itself, and I assume that you at least know what DNS is used for, and how to setup a simple DNS domain. If you don't know, read some DNS tutorials that you'll find anywhere (using your internet best-buddy, google.com), and check out the RFC's for DNS. Also, I haven't really tried this with MS systems (Such as Windows NT or Wnidows 2000), if anybody does, please feel free to drop me a note and let me know how it went/what you found and I'll include the details in the next revision of this document and give you credit. Otherwise, I'll have to do it myself, and I'm a lazy little prick at the best of times.
