Hello people!
I want to set up a network and simulate DDos attacks on it. I don't have 500 computers to upload sub7 to, so are there any alternatives?
What I want to investigate is if there are any types of routers or network infrastructure that will stop or minimize the damages of DDos attacks.
Any suggestions?
Yup, get a couple of dozen machines and install linux on them. Login/Su as Root, then issue the command: ping -f -s 65507 your.tar.get.host
The -f command under linux causes a flood of pings. It does not report the time it takes for the packet to answer back, it doesn't care. It's basically there just to flood the network with packets, in order to see where any faults may lie.
The -s 65507 part sets a packet size of 65507 bytes (the largest permitted by the ping program).
This will simulate a small ICMP on Windows-based DoS of about 25-35 machines (my estimation). If that doesn't read clear enough: a dozen linux boxes using ping -f -s 65507 is roughly equivalent to 25-35 windows boxes using ping -l 65500 -t -w 0
Other than that, there's nothing really easy to do it with.
That's a good piece of advice! :) I guess I could borrow a load of old pc's from somewhere. It's not gonna be easy borrowing a big enough car, though.... ;)
A linux box running LaBrea will reduce the total amount of traffic sent at you by 80% in my tests. It just depends on the type of DDos you run into. Just an FYI
