What is NAT 2008-03-09 09:50:00 NAT stands for Network Address Translation. It is actually a service which your router preforms for your local PC-s.Why it does that? Because every computer must have its own IP address. Local addresses (ones in your home network) are usually 192.168.1.X (where X can range form 1-255) and they all need to connect to the internet. How they accomplish that? They connect to the gateway which can be actual PC or ADSL modem configured to be in a router mode, which is connected to the internet. Because you have only one line, you can have only one internet connection and consequently you can get only one external IP address at a time. This is what gateway is for.It connects to the internet and gets its external IP address and then it redirects all computers in a Local Area Connection to the outs
MSN messenger worm(s) 2008-03-08 16:09:00 Why i chose to write about this worm? Simple. Because i'm tired of it... seriously, when you keep getting 2-4 new conversation windows every minute, and each of them spits out the infamous "Check out my pictures" message, you can either do something about this or uninstall messenger.... permanently.First to explain that "worm(s)" from the title:Yes, unfortunately there are multiple mutations of this worm, and infection spreads faster than ever because of naive and inexperienced PS users. Typically infected computer sends messages and/or some file through MSN messenger. You will get a message saying something like "hey check out these pics of mine", which is followed by a link or a file which user can accept and download to his PC. Just decline the file and everything will be fine, if you
Potentially dangerous filetypes 2008-03-12 11:55:00 First of all: why potentially? Because these filetypes are common on a tipical system and some of you may already know this, some of you don't but not all file types can pose a threat to your system, and even those that can, are most usually clean (in fact vast majority of them are needed for proper system operation). File types that can potentially pose a threat to your system are the ones which contain executable code, or some metadata that involves internet.So you have two groups:System executable codeSome scripting language code or metadata informationGroup one: system executable codeFile types in this group are the ones containing machine code, system executes these at its lowest level by basically loading them in the memory and jumping to the first instruction. These file types pose Read more:dangerous
Try Firefox 2008-03-17 11:13:00 Some of you may remember that damn annoying spyware called "Cool Web Search", if you had it, you know how much pain in the ass it is (redirecting your homepage, trying to connect to internet if PC was disconnected, and generally slowing entire system down). I tried a whole dozen methods of removing it but to no avail because each time i started Internet explorer i would get it again. Then i remembered an article in one PC magazine, about firefox, the new browser (for that time) that is far more secure than internet explorer. I immediately installed it.. and kept using it ever since :)What's so special about firefox you might ask. Why a computer giant like microsoft can't make their own web browser (internet explorer) more secure than some open source one (firefox)? Ever heard of ActiveX? Read more:Firefox
