The Wonder that Wi- Fi is!!!!!

Hi friends, This is the first time that I had a practically experienced the wonder of Wi-Fi systems. It so happens, that one of my friends have set up a Wi-Fi Spot in their Home using a Broad Band Modem, a Wireless router, three Desktops and a Laptop. He has 2 Computers on Windows and 2 on Linux, that too different versions, one running on Fedora Core and the other on Knoppix Linux. It's just marvelous how these things connect to each other all having different OS. Can U believe it, I was accessing Internet from Linux and simultaneously sharing application and files with my Friends over the LAN. I could even share data with the Laptop & that too Wirelessly..Stop Marvelling and Start Feelin Well if you want to know more about Wi-Fi and want this kinda setup in your Home then follow the link http://www.geocities.com/sudipnandy2008. You may also mail him at sudipnandy@gmail.com . Well if you want to learn more than what he knows then you better take a free networking course online or spend money into some round the corner Training Centre ....

Technical Troubles Concerning VOIP

Hi I welcome you all Tech Savvy people:
Many of you by now must have used VOIP to talk to relatives in foreign countries but this what I got unearthing a Magazine about the security Problems.
VOIP is used by many portals and claiming to give you access Voice over Internet absolutely free or at Dirt cheap rates thus making it very easy for people to talk to relatives and Friends in other nations. Well this is where the problem lies.

Explanation:
The VOIP's work in an enviorenment where Terminal computers called as Nodes access the System via low level local host Servers and this access is called Network Protection Access(NPA) which was absolutely safe just a few years back. But the sudden booming demands for faster and Secure Network Access by various sources like
Wired Networks over Intranet, Remote Networks over Internet
Wireless Networks all require safe and sound network access. What the customer doesn't realise is the trouble which an IT company has to undergo to keep Hackers and Viruses at Bay for the Benefit of Users. Potentially every node accessing the Network is a Platform as well as a System Bug which can anytime gain access to the System via Secure Line Connection but it is the Job of IT Professional to stop unauthorized access. Thus the sudden demand of VOIP's potentially make every node untraceable as VOIP does not access the system through Secure Line Server and use hell of a Bandwidth to be used into talking thus creating a Secure connection via Port 80. The (NPA) thus can't protect the Servers and the Client's on the other ports connected in the Server secure connection as the Local Host Servers are not used for Firewalls and Spam Filtering. So next time you use VOIP think about the Havoc you may create to the Mother System......
