TL; DR:

Right, the basics you need to know in order to do this successfully:
Note: The chances of you getting caught ( and consequently arrested) for this are minscule however it is always possible that you could. This is why we are going to use a vpn.

What does a VPN do?
A VPN essentially masks your own IP, and replaces it with the IP of the tunnel you are connecting through. Thus making it very difficult to trace you back – not impossible however.

Paid VPN’s (SAFE):

(WE DO NOT RECOMMEND!!!) Free VPN’s:

ProXPN – http://proxpn.com/
This is a free VPN trial. Sign up on the website using FAKE information apart from the email address which you will need to use to verify the account. Use http://10minutemail.com for a temporary email address.
Once it is downloaded, follow the install procedure and then connect to the VPN network – during the trial version you have to use a Miami IP. Using the internet becomes painstakingly slow and you WILL disconnect from the irc after connection.

PrivateTunnel – http://privatetunnel.com
Same setup as for ProXPN, however the trial has a day limit. Slightly faster however.

DoSing the servers:

http://www.hping.org/download.php – Windows/Linux
Easy to use system, when it has downloaded for your appropriate OS please install and choose to use either tcp or udp packets.

http://ha.ckers.org/slowloris/ – Linux
This script is a http DoS script, you MUST have perl installed.

http://hoic.99k.org/ – Windows.
Much like hping, this is more powerful than LOIC and very easy to use, install and it should be clear from there.

Thinking of Splashing out?
PAID VPN PROVIDERS:

Version corta:

LOIC ES PARA GAYS. PILLATE  UNA VPN PARA OCULTAR TU IP. UTILIZA HPING3, SLOWLORIS O SLOWPOST PARA ATACAR.
