These Internet Messengers are safe and useful as long as you limit your friendship with known people. However, it is not possible always.

However, we can find the layer 3 address of a chat contact if we try hard. This tutorial gives an outline to trace the actual location of a messenger contact.

This article is about certain tools which can tell you the status of Yahoo Messenger chat contacts whether they are online, offline or invisible.

Gtalk is one of the popular product from Google and most of the Internet users use it as their favorite Internet Messenger. This guide tells a simple method to detect any contact who appears to be offline but actually in invisible mode. I strongly recommend you to select Go Off the Record option before trying this trick but it is not necessary. If the user is chatting from Gmail, this trick may not work.

Select the button Never save chat history


Save changes

Start Ad-hoc Network To Share Internet and Files

There are two modes of networking; infrastructure mode and ad hoc mode. In infrastructure mode, we use a central device like router or Access Point to connect all devices. This central device share Internet and files among devices connected to it. If you establish a direct connection between two devices without a router or AP, it is called an ad hoc network. In ad hoc mode, we can share the Internet and data between computers. That means in an AD-Hoc network, there is no base station to control and coordinate the packet flow. Here packets are flowing from one computer to another directly and can be compared with walkie-talkies because participating devices communicate directly with each other without any third party devices.


Create Ad hoc Network
Windows support ad-hoc networking. For example, if you want to share a broadband connection on your laptop with other computers in your home, you can simply do it by establishing an ad-hoc connection. Once you have created such a network on y…
