I know this is a slightly odd request but it’s for a project I’m working on to create a traffic generator to simulate DDOS (distributed denial of service) attacks to public websites which have been plaguing the internet especially lately. I have an IXIA packet generator which can manipulate any UDP/TCP packet but it costs a lot of money to maintain that equipment in software maintenance etc… I think I should be able to create a couple of simple scripts in ruby to simulate a SYN attack by opening let’s say 200,000 port 80 requests to a web server in my lab, and want to be able to do this from several different machines using the same spoofed source IP address. Based on my experiences with real case studies, I am finding that this takes place on an every day basis to many sites on the internet causing their routers, firewalls and webservers to crash due to receiving too many packets/second and not necessarially due to exceeding bandwidth. The people who are performing these attacks are sourcing their IP’s from places in the middle east and many times, send an extortion letter to the company demanding money in exchange for a promise to stop taking down their website and denying service to paying customers…it’s a huge problem on the internet today. There isn’t much publicity regarding these types of attacks because companies are trying to keep it as low key as possible to prevent from loosing customers. The horror of it is, it has been reported that 90% of companies receiving extortion letters actually pay these people! Back to my original question…any assistance to help me create this type of free open source packet generator would be greatly appreciated. thanks jackster ---

Maybe you want to have a look at scruby first. [http://sylv1.tuxfamily.org/projects/scruby.html](http://sylv1.tuxfamily.org/projects/scruby.html) It’s simple to add new dissectors and has a good documentation. Greets, Sandor Szücs ---

Thanks alot Sandor…Scruby looks like exactly what I was thinking of…I’m going to give it a shot. jackster Sandor Szücs wrote: > Hi, > > On 27.02.2008, at 15:22, jackster the jackle wrote: > > > Back to my original question…any assistance to help me create this > > type of free open source packet generator would be greatly > > appreciated. > > Maybe you want to have a look at scruby first. > > [http://sylv1.tuxfamily.org/projects/scruby.html](http://sylv1.tuxfamily.org/projects/scruby.html) > > It’s simple to add new dissectors and has a good documentation. > > Greets, > Sandor > Sz�cs
