Preventing DDoS attacks

[Robbie]

Hey guys,

My dedicated server has been undergoing many DDoS attacks by a main competator,

I got told by John to post in this forum so here is the message he told me:

This is something that you would need to troubleshoot on your end, as we don't have layer 3 hardware between you and InterNAP -- the traffic just goes right through. If you'd like more information on how to take a traffic dump and apply firewall rules to mitigate the attack, please make a post here: http://www.nfoservers.com/forums/viewforum.php?f=44.

Thanks,
John
Founder/President

So if you guys know how to intergrade DDoS protection or firewall settings for my server let me know please!

Information:

O/S: Centos 64bit

- Thanks

While the attack is in progress, please run a command like this:

Code: Select all

tcpdump -X -n -c 100

That will give me output that I can use to suggest an iptables firewall rule to mitigate your specific attack.

just waiting for the attacks to happen again!
