pinged and syn flooded to death..my pc is about shot and i need a solid defense if there is any please let me know. and to set my impression right..i'll say i only know half the basics and in the process of learning...thanks

I hope you have a firewall set up. First thing is to set it to ignore ping requests. Good Idea in general because it will decrease the number of random ports scans.


Here are some ragistery tweaks. I take no reponsibility if they destroy your box.

hkey_local_machine \system \currentcontrolset \services \tcpip \parameters \synattackprotect=1 REG_DWORD

hkey_local_machine \system \currentcontrolset \services \tcpip \parameters \tcpmaxconnectresponseretransmissions=2 REG_DWORD

hkey_local_machine \system \currentcontrolset \services \tcpip \parameters \tcpmaxdataretransmissions=3 REG_DWORD

hkey_local_machine \system \currentcontrolset \services \tcpip \parameters \enablepmtudiscovery=0 REG_DWORD

Microsoft has a decent article whiich is where I got the reg hacks.

Are these attacks on a personal machine or company webserver?

I always found the best way to avoid DDOS is not to piss ppl off, I dunno always worked for me

Your connection can only handle so much traffic, even if you're dropping it. Sometimes there is no defense at the endpoint and steps need to be taken in the core routers of your ISP.

MpR uses the approach that I do, don't piss people off.
