I was on skype the other day and someone i had added a long time ago skyped me and i knew he streamed (That is when i added him, whilst watching him) and so i checked to see if he was streaming before i answered and sure enough he was with my skype on the screen. I ignored it and watched to see his reaction and he did it again once the skype call failed, i ignored it and same again. Then when he did it again i answered but stayed silent, he went onto his start menu and oppened an app which came up with loads of numbers and i hung up the call because it alarmed me. Someone in the chat then said 'I see your ddosing someone, need help?' and he then said 'the call was too short so i couldn't do it, your lucky this time' (Call time was about 15 seconds). This has really alarmed me so i am asking if anyone knows a safe and free way to defend against any future attacks from this person and any other people who may try and ddos me, i do not really understand what ddosing actually is, what they do, how to protect against it or the dangers of it. If anyone could hep me out i would really appreciate it! Thanks Guys, last time i had a problem you guys were all really helpful so hopefully i can feel safe again soon

P.S. Sorry if this is in the wrong place, i dont know much about computing so i do not know what this is classed as

DDOS - Distributed Denial of Service.

Causing so many repeated requests to a server that legitimate traffic cannot get in.

You have a server. Be it a Skype client, or a web store. Something publicly accessible.
I have a botnet of 50/100/10,000 zombie PC's. (I don't really, but just for discussion's sake)

I can cause them to attempt to connect to your server, or request some data, at such a frequency that legitimate traffic cannot get through. Your server is overwhelmed.
If it is a webstore, a few hours, or day or two of that will cause you significant monetary losses.

Defense? On a home scale, nothing really, except choose your contacts wisely.
On a corporate scale? Detect the pattern, and automatic fail over to another server with...

They were just pulling your chain. DDOS stands for Distrupted Denial of Service. Basically, it's an attempt to flood your computer with worthless information causing information that is needed to be lost. But, in general it requires a few computers to be sucessful in order to generate the required amount of worthless information. You can't do it over skype however.... simply running a bunch of numbers across the screen doesn't count lol Also, most routers will protect against a DDOS along with internet service providers...

So i do not need to worry? Is it a danger? What could he have done if I hadn't of hung up? Just so i know that if he tries again there is absolutely nothing he can do

As far as 'absolutely sure'? Hey...it's not MY system/network.
I'd just leave him alone. He'll forget about you after the next Mt Dew.
